The Investigative Process

Investigators involved in child maltreatment cases must determine if a crime has occurred. If a crime has occurred, officers must determine who is responsible, if any actions on law enforcement's part are necessary to protect the child, and if criminal prosecution is warranted. To answer these key questions, investigators must complete a number of tasks to collect necessary information.

Interviewing the Reporter

The investigator must have certain information prior to initiating the investigation. An adequately trained officer or CPS caseworker may have already obtained the necessary information. If not, or if some additional clarification is necessary, the investigator should contact the reporter directly.16

The more comprehensive the information provided by the reporter, the better able investigators are to determine the appropriateness of the report for law enforcement or CPS intervention and the better able they are to determine the level of risk to the child and the urgency of the response needed. Information gathering should focus on demographic information about the child and family; information about the alleged maltreatment; and information about the child, the parents, caretakers, and the family as a whole.

Demographic Information17

Demographic information serves two primary purposes: to locate the child and family and to assist in the assessment of risk to the child. Each State defines the scope of demographic information to be collected. In general, officers should gather information regarding:

  • The child's
    • name, age (date of birth), sex, and race; and

    • permanent address, current location, and school/day care attending.



  • The parents'/caretakers'
    • name, age (date of birth), and race; and

    • permanent address, current location, place of employment, and telephone number(s). (If the person alleged to have maltreated the child is a caretaker other than the child's parents, the above information should be gathered for both the parents and caretaker.)



  • The family composition
    • names, ages (dates of birth), sexes, race, and location of all children in the family;

    • names, ages (date of birth), and location(s) of other children in the alleged offender's care (if the offender is not the birth parent, e.g., a babysitter);

    • names of other relatives and nonrelatives living in the home;

    • names, addresses, and telephone numbers of other relatives and their relationship to the child; and

    • names, addresses, and telephone numbers of other sources of information about the family.


  • The reporter's name, address, telephone number, and relationship to the child/family.

Information Regarding the Alleged Maltreatment

Investigators should obtain information about the type(s), nature, severity, chronicity, and the location(s) where the alleged maltreatment took place.

  • The types of maltreatment. This refers to physical abuse, sexual abuse, neglect, and/or emotional abuse.

  • The nature of the maltreatment. This refers to information regarding the specific characteristics of the maltreatment.
    • physical abuse: burns, beatings, kicking, biting, etc.;

    • neglect: abandonment, withholding of needed medical care, lack of supervision, lack of adequate food or shelter, emotional deprivation, failure to register or send to school, and failure to thrive;

    • sexual abuse/exploitation: fondling, masturbation, oral or anal sex, sexual intercourse, pornography, and forcing the child to engage in prostitution;

    • emotional abuse: constant berating and rejecting treatment, scapegoating a particular child, and bizarre/cruel/ritualistic forms of punishment (e.g., locking a child in a dark closet, tying a child to a bedpost, or constantly belittling and demeaning a child); and

    • parental/caretaker acts/omissions such as accidental versus intentional/premeditated, disregard for the child's age or condition, and instruments used.


  • The severity of the maltreatment. It is important to obtain information from the reporter regarding the emotional and physical injury to the child.
    • extent of the physical or emotional effects on the child (e.g., second- and third-degree burns on half of the child's body, withdrawal, suicidal behavior, and excessive fear); and

    • location of the injury on the child's body.



  • The chronicity of the maltreatment. Information gathering should focus on:
    • whether there have been prior incidents of abuse or neglect;

    • how long the abuse or neglect has been occurring; and

    • whether abuse or neglect has increased in frequency or remained relatively constant.



  • The location of the incident. It is important to ascertain the setting where the actual abuse or neglect occurred (e.g., home, school, supermarket).

Information Regarding the Child

To effectively evaluate the level of risk to the child and determine the urgency of the response, officers should obtain the following information from the reporter.

  • The child's physical and emotional condition. This relates to the child's current condition and should consider any ongoing disabilities the child may have.

  • The child's behavior. For example, does the child exhibit extremes in behavior?

Information Regarding the Parent(s)/Caretaker(s)

If the reporter has the information, it is important to gather as much information as possible about the parents/caretakers. Knowledge of the parents'/caretakers' emotional and physical condition, their behavior, history, view of the child, child rearing practices, and quality of their relationships outside the family helps to determine the level of risk to the child.

  • The parents'/caretakers' emotional and physical condition (e.g., do the parents/caretakers misuse drugs/alcohol? Are the parents/caretakers physically ill or incapacitated?).

  • The parents'/caretakers' behavior (e.g., do the parents/caretakers engage in violent outbursts? Do the parents/caretakers engage in bizarre irrational behavior?).

  • The parents'/caretakers' history (e.g., were the parents/caretakers traumatized or victimized as children? Do the parents/caretakers have a history of trouble with the law?)

  • The parents'/caretakers' view of the child (e.g., do the parents/caretakers view the child as
  • The child rearing practices (e.g., do the parents/caretakers have unrealistic expectations of the children? Do they use verbal and physical punishment as the first response to misbehavior?).

  • The parents'/caretakers' relationships outside the home (e.g., do the parents/caretakers have friends and what is the quality of those friendships?).

Information Regarding the Family

CPS caseworkers need to gather as much information as possible about family characteristics, dynamics, and supports.

  • The family characteristics (e.g., is this a blended or single parent family? Is there inadequate family income?).

  • The family dynamics (e.g., is spouse abuse occurring? Is there marital conflict or poor communication? Is the family characterized by disorganization or chaos?).

  • The family supports (e.g., are extended family accessible and available? Is the family connected in the community?).

Gathering this indepth information is essential because it helps to determine how quickly an investigation must begin. It enables officers to identify the victim(s), the parent(s)/caretaker(s), and the offender and determine how to locate them so that the initial investigation can be conducted. It also identifies other possible sources of information about the family that will help evaluate the possibility of past, current, or future abuse or neglect. Finally, it will assist the investigator in accurately and effectively planning the approach to the investigation.

Field Interviews

Physical Neglect

While neglect allegations are the most common form of child maltreatment reported to child protection agencies, criminal investigation and prosecution occurs in only a small minority of the cases. Allegations of physical neglect normally involve the care the child receives in his/her home. The first step in such an investigation is to visit the home, generally on an unannounced basis. The neglect may involve environmental hazards, a lack of supervision, abandonment, malnutrition, failure to provide medical care, or other factors. The officer investigating possible environmental hazards in the home should examine the living conditions with the permission of the occupant or, in extreme cases, under the authority of a search warrant. The investigator must draw a distinction between poverty, a dirty house, poor housekeeping and clutter, and true environmental hazards to the child. The distinction is best made by separating poverty or life style factors from those conditions that will adversely affect the child's health and safety. Significant amounts of human or animal feces; exposed live electrical wires; extreme rodent and insect infestation; rotting garbage; and structural damage to the house, exposing the child to the risk of illness or injury, may independently or collectively constitute child neglect.

Unless law enforcement officers find clear and present danger requiring immediate action, they will rarely act independently in cases of child neglect. CPS staff are often in a better position to work with parents to reduce the risks to the child without unnecessary removal from the home. In fact, under Federal law, Public Law 96-272 (and many parallel State laws), the juvenile or family court requires CPS agencies to demonstrate that they attempted reasonable efforts to prevent out-of-home placement. Some communities have many options for avoiding foster care placement in neglect cases. These include intensive family preservation programs, day care, teaching homemakers, parenting classes, and traditional counseling. For some neglectful parents the answer is financial aid, with CPS referring them to income maintenance and job search programs. Law enforcement officers generally lack access to those services and consequently are handicapped in neglect investigations unless CPS is involved.

There are situations in which law enforcement may determine that independent action is required. These include times when CPS is not accessible and when:

  • very young children are left unattended and no one can contact a responsible adult caretaker;

  • the adults are under the influence of drugs or alcohol and their actions or inability to act constitute a clear threat to the child's safety (i.e., Driving-Under-the-Influence (DUI) or Driving-While-Intoxicated (DWI) or actual and threatened use of firearms); or

  • the adult caretakers are/have been arrested and no responsible caretaker is available to care for the children.

A child neglect investigation includes a visit to the child's home or place where the neglect is alleged to have occurred to determine the physical conditions present. The investigation should include an interview with the caretaker(s) to determine their perception of the situation and to assess their ability and willingness to care for the child. The investigation may include securing medical assessments of the child, particularly in cases where malnutrition, failure to provide medical care, or improper physical care is alleged. A combination of medical exams and psychological or developmental assessments may also be useful, particularly when neglect is alleged to adversely affect the development of small children or in cases of emotional neglect. The CPS caseworker generally arranges for these assessments.

Physical Abuse

Criminal prosecution of physical child abuse is more common than prosecution of neglect, and the role of law enforcement becomes clearer. The first step after conferring with the complainant is to interview the child. The investigator, preferably acting as part of a team with CPS staff, can explain to the caretaker that the agency received a call concerning the child and that they would like to talk to the caretaker about the child's condition. It is important to avoid using the term child abuse at this stage as it has different meaning for different people and can elicit intense feelings resulting in parental resistance in the interview. Some parents may admit to disciplining their children in a way that accidentally caused severe injury. In reality, much physical abuse, if not most, is the result of the offender's efforts to discipline the child and a failure to control the situation, his/her temper, or the force used. However, caretakers rarely view what they have done as abuse.

Interviewing the Alleged Victim

After explaining the reason for the visit, investigators should ask to see the child. One of the investigating team members should explain, if the child is old enough to understand, why they are there and what they will be doing. Depending on the allegations and/or the child's age, the investigator will need to visually examine the child for signs of obvious trauma. Investigators should document any injuries noted and, if possible, photograph areas of injury or of questionable physical findings. The child should be interviewed outside the presence of the caregiver. The investigator is interested in such issues as:

  • establishing the child's developmental level;

  • the child's explanation of any injuries;

  • who the child perceives as his/her caretakers;

  • how the child is disciplined;

  • how other children in the home are disciplined;

  • how often have the victim and/or siblings been injured in the past;

  • what type of weapon or implement was used, and where it is now;

  • if they bled after the assault, where their clothing is now, or any other item that might have been stained;

  • who else saw the incident; and

  • whom the child told of the incident.

If the investigator finds the child has sustained life threatening or severe injuries, the first priority is securing emergency medical attention for the child.

Interviewing the Caretaker

After talking with the child and assessing the presence of obvious physical findings, the investigator should talk with the caretaker(s). The caretaker should be asked for his/her explanation of any injuries. Again, the investigator should make an initial assessment of the match between the injuries and the explanations the child and adult caretaker(s) provide. The investigator should remain nonjudgmental and matter-of-fact during this stage, since some people who physically abuse their children fail to recognize the impropriety of their actions and will openly acknowledge what has happened. If they recognize that the officer disapproves of what they have done, they will attempt to cover up their actions. In cases of significant injury, however, such resistance can be expected. If CPS staff are present, they may need to talk with the caretaker(s) about their background and current living situation to assess the risk of future abuse.

The investigator may find that there have been a number of persons caring for the child during the period of injury, and the child may not be willing or able to identify the person responsible for the injury (due to trauma or age). In this case, the officer should obtain details about who has recently cared for the child, for what time periods, and if anyone else was present, building a chronology of care so the investigator knows the transition points between these caretakers. Names, addresses, and telephone numbers should be secured. If any of these caretakers are present, the investigator should discuss the injuries with them as well. If there is any question about who is responsible for the abuse, all caretakers should be asked what signs of injury they observed, when they first noticed them, and when was the last time they knew those injuries were not present. Investigators should also determine what they know of the other caretakers' actions, of any past history of injury to this or other children in the home, or other relevant factors.

Interviewing Other Children

If other children are under the care of the same people, the investigator should talk with these children and perform, as appropriate, a screening for signs of physical injury. Other children should be asked about any injuries noted, as well as their observations about the injury on the alleged victim. Even if no sign of abuse is present in these children, they may be able to provide valuable information about family interactions, such as how discipline is handled, by whom, whether it varies from child to child, etc.

Medical Examination

When there is evidence of injury in cases of physical abuse, it is advisable to secure a medical examination of the child as soon as possible. The physician can document any injuries and treat any conditions present. The physician can also check for injuries with little outward manifestations such as internal bleeding, old fractures, or shaken infant syndrome. The doctor can also assess the developmental level of smaller children. Perhaps the most valuable role of the physician (after the treatment of any injuries) is to assist in the assessment of the match between the injuries noted and the explanation offered. For example, if the parents say that a 1-month-old child pulled himself up in his crib and tumbled out, the physician can explain the implausibility of the story based on child development and show that the injuries sustained are not consistent with a fall but the result of violent shaking.

Crime Scene

While the order of these steps may vary by necessity, the law enforcement agency may wish to seek physical evidence to substantiate any criminal charges. Using either a consent to search or a search warrant, the officer will be interested in the instrumentalities of the crime, such as the rod, coat hanger, bed board, belt, etc., used to inflict the injuries; blood-stained items such as children's clothing; and the exact location where abuse occurred to possibly photograph blood splatters on wall/floor/furniture, etc.

Interviewing the Alleged Perpetrator

In the event a possible or alleged perpetrator is not the caretaker already interviewed, the officer should interview the subject. The interview of this person should be postponed until the investigator can get a clear idea of what has happened (unless the delay exposes children to undue risks). The interview should parallel the caretaker interview, seeking information nonjudgmentally, which will generally yield the best results. Again, the officer is not seeking an admission of responsibility for "abuse," but seeking an acceptance of responsibility for the injuries sustained.

Sexual Abuse

Due to the nature of child sexual abuse, law enforcement and CPS are strongly encouraged to approach the allegation of sexual abuse as an investigative team. This will reduce the number of interviews the child must experience and improve the investigative outcomes of both agencies. Prior to initiating the field investigation, investigators must make several key decisions.

  • Who will take the lead in interviewing the alleged victim, siblings, or other child victims or witnesses?

  • Who will be present during the interviews?

  • Will the interviews be audiotaped or videotaped?

  • Where will the interviews take place?

  • Who will interview nonoffending adults?

  • Who will interview the alleged perpetrator(s)?

Interviewing the Alleged Victim

Once the aforementioned decisions have been reached, the investigators should proceed with the field investigation. Generally the first step, after clarifying necessary information with the complainant, is to interview the alleged victim. For the most part investigators should seek to arrange this in a neutral setting and away from the place where the abuse may have occurred. The location of the interview should de-emphasize the "power" of the alleged perpetrator. For example, if the child is alleged to be abused by his/her father, then an interview in the family home is generally ill-advised because of the sense of power the child may perceive from the perpetrator, even if he is not home. However, the location should be in a place where the child can feel comfortable. Consequently, a busy police station may also be unwise. Many investigators have had success interviewing children at school, at a CPS interview room, or in a special room at the law enforcement agency. If the abuse occurred outside the home by a nonfamily member, the child's natural home may be the best location. The actual interview should be conducted consistent with the "Special Considerations for Interviewing Children" chapter of this manual.

Because of the nature of sexual abuse, the victim interview plays a far more critical role than in other forms of maltreatment. In sexual abuse cases, the investigative interviewer must be extremely thorough. The investigator must:

  • Develop an understanding of the child's developmental level and vocabulary.

  • Determine what, if anything, of a sexual nature the child says happened.

  • Establish whether the incident appears to be sexual in nature or can be reasonably explained by normal caregiving activities.

  • Determine how the incident fits into the normal pattern of care by the alleged perpetrator.

  • Establish the date of the last event as accurately as possible.

  • Determine if this abuse has happened before. If so, determine when and how often.

  • Determine how the child was introduced to the activity; what transitional behaviors preceded the sexual interaction. Determine if elements of progression were present (i.e., moving from less intrusive to more intrusive forms of sexual activity).

  • Determine whether the child believed that the sexual interaction was to be kept a secret and how that was communicated.

  • Establish if there were subtle or overt bribes, enticements, or threats used in the engagement process.

  • Determine what forms of coercion or pressure were employed to maintain secrecy.

  • Determine what the perpetrator did before the incident; the events that transpired immediately before the incident; what the perpetrator said before, during, and after the event; and what happened after the incident.

  • Establish whether the child can provide explicit details of the sexual interaction.

  • Determine what the child remembers, including sensory details of the event. Find out if the child heard any sounds. Establish what the child saw from his/her perspective.

  • Determine whether any physical items were used in the abuse that might become the object of a search and seizure.

  • Establish if the child was wearing any clothing that may have become stained or torn and is it available.

  • Determine if photographs or videotapes were made.

  • Find out if any weapons were used or suggested by the perpetrator.

  • Determine whether there are any idiosyncratic details that lend authenticity to the child's account.

  • Establish if the child sustained physical injury as a result of the sexual activity.

  • Find out who else was present and who may have any knowledge of the events.

  • Determine if any other children were present or if the victim is aware of others who may be victims.

  • Find out whom, if anyone, has the child told of the incident, in part or whole.

  • Establish the role the nonoffending parent played and how he/she reacted to the disclosure.

Interviewing Other Children/Siblings

After interviewing the alleged victim, the investigator should also talk with any other children identified as possible victims or witnesses for information about sexual activity directed at them or for any corroborating or conflicting information that they can provide. The child witnesses may not have direct knowledge of the incident, but may be able to confirm that the victim told them of the incidents long before the disclosure to adults. These other children may confirm elements of the victim's statement, such as seeing the perpetrator leaving the victim's room, hearing the victim's cries, or simply confirming the household routine that allowed the perpetrator to be alone with the victim as the child alleged.

Interviewing Other Adult Witnesses

Any adult witnesses who can shed light on the allegations should be interviewed for much of the same information as described above: what did they see, what were they told, and how did they react.

Interviewing the Nonoffending Spouse

In intrafamilial cases, the nonoffending parent, most commonly the mother, will be the next family member interviewed in depth. Frequently, this is the most difficult interview for the investigator. The primary goals of the officer's interview are:

  • To learn what the nonoffending parent believes has happened and to provide corroborative evidence to support or refute the child's statement.

  • To assess the capability and willingness of the nonoffending parent to protect the child in order to provide the child with a supportive environment. This is necessary for the child to heal and to enhance his/her ability to handle the challenges that the criminal justice system demands of the survivor of sexual abuse.

This interview, like that of the victim's, should be conducted in a neutral setting if possible. Only the interviewer and the parent should be present. Because of the nature of some of the questions the officer asks the parent (such as the concern about spousal violence or quality, quantity, and type of sexual activity engaged in with the offending spouse), the element of privacy should be maintained.

During the early stages of the interview, the investigator should convey an attitude of concern for the nonoffending parent and the child. No guilt or recriminations should be indicated by the interviewer. The interviewer should reassure the parent as much as possible that there is a legitimate investigative necessity for not only this interview but for specific questions that will be asked. The attitude of the interviewer should be that of seeking the truth and discovering what actually happened.

In general, the investigator wants to determine what the parent knows about the sexual abuse. The investigator should tell the parent only what is absolutely necessary about the child's disclosure. The investigator should not reveal anything during this interview that should not be repeated to the perpetrator. It is frequently best to use generalities, at least in the initial stages of the interview. There are a number of possible reactions to such information ranging from anger and grief to total disbelief and hostility. The interviewer might find it necessary to give the parent several minutes to ventilate and express his/her feelings before bringing the interview back on track. Some nonoffending parents will be very concerned about what will happen to them as opposed to the child's immediate well-being. While taking note of this attitude, the interviewer can make it clear that this will be discussed at a later time.

It is necessary for the investigator to determine how much of the child's statement the parent can corroborate. As in all interviews, it is frequently best to let the parent talk about his/her knowledge in a flowing narrative style, and then go back to ask specific questions at the end of this parent's recitation. Specifics to be covered should include:

  • Can the parent confirm any behavioral indicators?

  • Does the parent recall any times when the sexual activity could have taken place?

  • How long has the nonoffending parent known about the allegation?

  • How did the parent become aware of the allegation?

  • If the child disclosed, does the nonoffending parent believe the child? If so, why? If not, why not?

  • What action has he/she taken since the child revealed the incidents?

  • What statements has this parent made to the child concerning the allegations?

This information is extremely important in assessing the cooperation of the parent, his/her ability to influence the future cooperation of the child, and his/her desire and ability to protect the child from further abuse.

Other circumstantial evidence that this parent could provide to enhance the credibility of the child's statement includes a description of household routine; for example, which parent is the primary disciplinarian; who controls the finances; and what is the child's daily routine. These can be explored early in the interview in a manner that gives the nonoffending parent a chance to talk about nonsexual and less threatening matters first. The investigator needs to obtain all possible details during this initial interview. Once the nonoffending parent has had a chance to think about possible consequences of the situation or talks with the molester or other family members, he/she might be reluctant to expand on any statements that verify the child's account.

Once the investigator has an understanding of the family dynamics, he/she can move to the more sensitive issues:

  • What is the nonoffending parent's relationship to his/her spouse (the offender)?

  • Is there a history of violence between the alleged offender and family members?

  • Is the nonoffending parent physically afraid of the alleged offender?

  • What is the sexual relationship between the parents (i.e., frequency of sexual activity, type of sexual activity, does the alleged offender have the spouse engage in actions such as shaving the pubic area, wearing "juvenile" clothes, or speaking or acting like a child)?

  • What sort of material does the suspect read or collect (soft-core pornography, hard-core pornography, child development literature, general sexuality literature, "detective" magazines, etc.)?

  • What is the suspect's relationship with children other than the victim?

  • Is there a history of arrest for any family members? If so, for what?

  • Have there been any hospitalizations or psychiatric treatments for any family members? If so, where and for what reasons?

  • Is there substance abuse by family members? The investigator should keep in mind that substance use/abuse by the alleged offender may be used by the defense as a mitigating factor in establishing the defendant's lack of responsibility. Substance use/abuse by the nonoffending parent might be critical in his/her inability to protect the child in the past and future. Substance abuse by the child might be a behavioral indicator of abuse.

  • Does the nonoffending parent know the background of the suspect (i.e., was the offending spouse sexually or physically abused as a child)?

  • Were there any prior marriages or children by other individuals? Does this parent know their names and current locations?

  • What is the employment history of the offender?

  • What is the military history of the offender?

  • What is the nonoffending parent's relationship with his/her children, particularly the victim?

If the nonoffending parent is appropriately concerned, believes the child, and is supportive of the goals of the investigation, this parent can be enlisted as an ally with the investigator to help the child. If this parent does not believe or support the child or demonstrates a hostile, punitive, or rejecting attitude toward the child, then he/she cannot be considered properly protective of the victim. Out-of-home placement of the child should be discussed with CPS staff in these situations.

The interviewer should be aware of the services such as temporary shelters, financial assistance, medical and psychological assistance, etc., that are available for the nonoffending spouse and children. It is preferable to have this information in written form, which can be left with the nonoffending parent.

If possible, end the interview on a positive note, giving the nonoffending parent a card with the investigator's name and telephone number. Let the parent know that if he/she needs any assistance or thinks of anything that would help the child to feel free to call. The investigator should prepare the parent for further intervention of the criminal justice system, such as the possibility of preliminary hearings, grand jury proceedings, videotaped interviews, medical examinations, etc. The interviewer should attempt to address any concerns and answer any questions that the parent has at this time.

The law enforcement investigator should remember that if circumstances warrant, charges can be brought against the nonoffending parent for either complicity in the sexual abuse itself or failure to protect the child. This should be discussed with the team and the prosecutor, if appropriate.

Interviewing Parents in Out-of-Home Abuse Cases

In out-of-home abuse cases where the perpetrator is not a family member, parents are interviewed after the child has been interviewed. Investigators are interested in what the child has told the parents concerning the assault(s) and in physical or behavioral indicators that they may have observed. In cases where the offender is someone known, the investigator wants to explore the parents' relationship with the offender, how they first met the offender, what the offender told them he/she was doing with their child, and how the offender responded to particular questions the parents asked concerning activities with the child.

It is important to confirm whether or not the parents believe the child and what plan they can develop to prevent further abuse. Investigators should offer parents an explanation of the steps in the investigative process and discuss the possibility that the child may recant the disclosure. Parents should be instructed not to question the child about the abuse but be prepared to discuss it if the child brings it up. Investigators should give parents a name and number to call if they have problems during the investigation or think of further details relevant to the case.18

Medical Examination

Generally the next step in the investigative process is to arrange a medical examination, as appropriate. Some controversy exists as to which children should be physically examined. Advocates for exams for all alleged victims argue that the exam may provide evidence of genital trauma, venereal disease, or the presence of sperm even in cases where no abuse was disclosed by the child or the abuse was minimized by the victim. Another reason offered for examining every child is that it will assure the child victim that he/she is unharmed and allay any fears that they have been damaged. Other researchers suggest that requiring a child who has not been abused and denies any contact to undergo a genital exam is very stressful in its own right and may unnecessarily traumatize the child.

Evidence of sexual assault can be medically detected in only a minority of cases. Muram, for example, reported that only 45 percent of the cases studied revealed clear evidence of sexual assault among cases in which the perpetrator confessed.19 Other researchers concur. Such findings are not surprising, given the nature of sexual abuse. Most incidents of exposure, fondling, forced masturbation, or oral sex would not be expected to leave medically detectable evidence. For this reason, the terms chosen by the physician for the exam report can be very powerful. A child disclosing a history of fondling to the examiner may be described on the report as having "no evidence of sexual abuse," subtly undermining the child's statement. The same physician may just as accurately phrase the results as, "consistent with the child's statement, no abnormal medical findings."20

Physicians and nurses specializing in child sexual abuse know ways to minimize the child's discomfort. Those working with the child should describe clearly, in terms the child will understand, what is going to happen, perhaps using anatomically detailed dolls. The child should be given as much control as possible over the exam. The examiner should conduct a general physical exam in a head-to-toe fashion, paying no more attention to the genitalia than is necessary. Tools such as colposcopes or special magnifying medical cameras may allow the examiner to see and record on film important findings.

The examiners should swab for sperm as appropriate to the case, which may include swabs of the mucus lining of the nose (where semen may have been aspirated after oral sex), vagina, rectum, or as indicated. Body orifices should be examined for trauma, unusual characteristics, or foreign bodies. Pregnancy testing may be appropriate, and venereal disease screening is often indicated. The body should be examined for teeth marks and signs of physical abuse.

The physician should take a thorough history from a child who is old enough to communicate verbally. This will help the examiner to focus the exam. In addition, statements made by physicians are admissible in many civil proceedings and, at times, in criminal trials.

In taking the assault history, the physician should ascertain the time lapse since the assault and the kind of sexual contact (e.g., oral, anal, vaginal, whether or not ejaculation took place, and whether or not a condom was used). The number of assailants, use of force or weapons, or injuries secondary to force/restraints/escape should be explored. The physician needs to question the child concerning post-assault symptoms such as pain, bleeding, bruises, loss of consciousness, nausea, or vomiting. An example of a question a physician could ask is: Did the child have any post-assault activities, such as bathing or douching, defecation, urination, eating or drinking (which would be important in cases of oral assault), or was the clothing changed? The physician should try to document any prior sexual contact the child has had.

The investigator should request legible copies of all medical reports and notes. The investigator should confirm how evidence collected during the exam will be handled to ensure the chain of custody. All samples should be labeled with the name of the victim and identification number and with the signature of the person(s) responsible for collecting and processing the sample. The evidence should be maintained in a locked environment and signed over only to representatives of law enforcement or the prosecutor.

Crime Scene Search

A primary objective of every law enforcement investigation of child sexual abuse should be to avoid having the child victim testify in court. Building a case so strong that the defendant will want to plead out rather than go to trial is one way to accomplish this goal. The presence of physical evidence is a key determinant toward this end. The investigator should view every case, no matter what the relationship between the offender and the child, as a case which he/she is preparing for vigorous prosecution. If, after the interview with the child, the investigator feels that this is a potentially valid complaint, the officer should proceed with the investigation, just as he/she would with any other criminal investigation.

One of the most important points to keep in mind in these cases is that corroborative evidence is extremely critical; all attempts should be made to secure any evidence that supports any statement that the child has made.

The investigator should also keep in mind standard investigative crime scene procedures and use these in all possible circumstances.

The following rules of evidence should be followed:

  • Recording. Officers should note the position and the condition of the evidence and its relation to other evidence. Also, they should note the date and time the evidence was collected, who found it, who collected it, how it is marked, etc.

  • Preservation. Officers should use: proper collection techniques, placing the evidence in a proper container; and marking the evidence.

  • Chain of evidence. Officers must list everyone who handles evidence.

  • Evidence of violence. Officers must look for weapons. The assailant with a weapon often leaves traces of his/her weapon or uses a weapon found at the scene and leaves it. Officers should note and photograph the victim's wounds and damaged clothing. Blood is important to note at the scene, as are signs of forced entry. These factors can help prove the element of force or lack of consent on the victim's part, which may be an issue at trial.

  • Stain evidence. Officers must look for many stains including: blood, semen, perspiration, saliva, etc.

  • Minute and latent evidence. Evidence collectors must always search for fingerprints and vacuum for hairs and clothing fibers, if practical. For example, in an incest situation, if pubic hairs are discovered in the prepubescent child's bed, the investigator may also want to search for underwear recently worn by perpetrator and not washed to check for pubic hairs. These should be sent to the lab for comparison.

  • Specific places to search.
    • Officers should search the bathroom for evidence, because the suspect may have bathed or washed the child.

    • Investigators should search for semen in the area where the assault occurred.

    • Officers must mark sheets or other fabrics on which a sexual assault took place on the exposed side, and they should then be folded. Fabrics that are not frequently washed, such as bedspreads, may show ejaculate long after the assault has taken place and should be submitted to the lab.



  • Evidence left. Investigators should collect articles of clothing left, stains, fingerprints, weapons, etc.

  • Articles taken. Officers should look for small items such as locks of hair, barrettes, panties, or pubic hairs which may have been taken by the offender as a souvenir or remembrance of the sexual activity.

  • Background evidence. During the interview, the investigator should ask the child about furniture, wallpaper, ceiling fixtures, anything that would be difficult for the offender to remove or change. The collectors should search for such evidence and record it with either photographs or videotapes. The child's ability to relate this information shows accuracy of memory. This may be important evidence in a court hearing.

  • Instrumentalities of the crime. Investigators should look for cameras, condoms, sexual devices, or any items that the child indicated were used in the commission of the sexual assault.

  • Lures. Officers should search for toys, games, stuffed animals, etc., that the perpetrator may have used to entice the child into the situation or into the location where the assault occurred.

  • Child erotica. Investigators should look for any material relating to children that is sexually arousing to an adult, such as child sketches, fantasy writings, diaries, and sexual aids. There is one important distinction between child pornography and child erotica. Although both are used for sexual arousal and gratification of the individual, child pornography has the added and more important dimension of effect on the child portrayed.

  • Child pornography. Officers should look for any visual or print medium depicting sexually explicit conduct involving a child. Child pornography is photographs or films of children being sexually molested. The sexually explicit conduct can include sexual intercourse, bestiality, masturbation, sadomasochistic abuse, and lewd exhibition of the genitals or pubic area. The child(ren) visually represented in child pornography have not reached the age of consent. This is in effect a crime scene photograph of actual child abuse. Mere possession of child pornography is a crime in many States and now is considered a crime in certain circumstances under Federal law. In 1990, Congress passed P.L. 101-647, which included a provision in Title III, section 323 that amended 18 USC 2252, making possession of three or more items of child pornography a Federal crime if anything used to manufacture the pornographic material crossed State lines, the film or photographic paper was made in another State, or the camera was made in another State or country. In addition, the use of the mail to send child pornography is a separate Federal offense. Officers discovering child pornography should contact postal inspectors and the Federal Bureau of Investigation if a Federal violation appears to be present. This can lead to increases in investigative personnel assigned to the case, charging in multiple jurisdictions, and an enhanced period of incarceration.

  • Adult pornography. Officers should look for the use of adult pornography. There are several uses in child sexual abuse. In some instances, the offender may need the adult pornographic material to arouse himself to complete the sexual abuse of the child. In other situations, the material is shown to attempt to arouse the child so that the sexual abuse can take place. Or the material is shown to the child to lessen his/her inhibitions and to give the child some ideas as to the sexual activities he/she would "enjoy" engaging in. When an investigator discovers quantities of adult pornography on the premises, he/she should seize the adult material and compare the scenes in the commercially produced magazines and videotapes with the sexual activity with the child(ren) to determine if the same or similar poses were used with the child victim(s).

  • Homemade pornography and albums. Investigators should seize child pornography or child erotica or simply a collection of nonsexual pictures of children such as school photographs. The nonsexual photographs may help identify other victims.

  • Personal letters and diaries. Officers should examine all correspondence found at a residence to determine the type of correspondence. Investigators should also search for diaries, which might summarize sexual encounters the perpetrator has had or even list names and ages of sexual partner(s) and a brief description of the type of sexual activity. Thus a diary may be helpful in determining other victims that this offender has abused.

  • Audiotapes. Officers should examine any audio cassettes. Some offenders will have the children talk onto cassette tapes. During these sessions, the children are encouraged to talk about the sexual acts they might perform or that they have performed before. In addition, sometimes the sexual abuse itself may be recorded on audiotape.

  • Home computers. When a home computer is present in the home of an alleged offender, the investigator should determine if it is being used to contact others of like interest. Computers are also used to store information concerning the pedophile's photographic collection and his/her victims to facilitate retrieval. Should the investigator find a home computer and believe that it has been used for this purpose, the computer should be seized (both hardware and software) for further evaluation. Care should be taken during shut down and removal so as not to erase any data.

  • Cameras. Investigators should seize still cameras and/or video cameras and recorder(s) if the child has related that he/she was photographed or was shown sexually explicit movies. All equipment used should be seized as well as undeveloped film found at the location. The video camera and recorder should be seized as well as all videotapes on the premises. These videotapes should be reviewed for content, despite the labeling on the outside of the cassette. The investigator should consult with the prosecutor to determine if a separate search warrant will be needed to view all the videotapes. Some agencies also seize any televisions used to show the videotapes to the child.

The investigator should be creative in the search. The search warrant should be broad enough to include items that might not be considered sexual, but which the child may have mentioned in the statement as used by the offender to entice the child, help consummate the crime, or record the crime.

Investigators must also consider the possibility of obtaining a legal consent to search when interviewing a nonoffending spouse in an intrafamilial case.

As mentioned earlier, if the investigator believes that such items may be destroyed or hidden after the child is interviewed, the investigator should take immediate steps to secure this evidence. This may involve contacting the prosecutor to expedite the issuance of a search warrant or sending officers to the location where it is believed this material is housed to secure it until such time as a search warrant can be obtained. The investigator should consult with the prosecutor regarding what circumstances would be considered exigent where the items could be seized without a search warrant. Telephone search warrants might be used in jurisdictions where they are permitted.21

Interviewing the Alleged Perpetrator

If the identity of the offender is not known, the investigator should conduct normal investigative procedures to ascertain identity. This means neighborhood canvases, all points bulletins, a check of local jails, hospitals, etc., that have had recent inmate releases, strangers in the neighborhood, and suspicious vehicles that may have been reported.

If possible, the timing of the interview with the offender should be selected carefully. Many sexual abuse cases have been lost or jeopardized because investigators moved too rapidly to interview the offender before they were fully conversant with the facts of the case. The investigator must keep in mind that the offender is, in many cases, not likely to cooperate with him or her unless the offender is convinced that the investigator has strong evidence to prove the abuse. However, in some cases consideration should be given to interviewing this individual early in the investigation where the element of surprise can work to the investigator's advantage. The offender, if unaware of the investigation, will not have prepared an alibi, retained an attorney, or destroyed physical evidence, all of which is possible if the investigator does not act swiftly. This should be evaluated on a case-by-case basis.

There is no one style of interviewing a suspected child sexual assault offender. Just as there are different types of offenders, there are different techniques that will work with various offenders. Adolescents, for example, account for a significant number of offenders, and the interviewing style and procedure must be adjusted, consistent with local procedure. As stated earlier, the primary objective of any investigation is to collect enough corroborative evidence so that it will not be necessary to have the child testify in court. Therefore, the interview with the suspected offender should be handled in a timely and skilled fashion. It is preferable that only one investigator be present during the interview. As in interviews with the child victim, the offender will often feel inhibited about his/her behavior if other persons are present. It is desirable that this interview be conducted in a room with a two-way mirror and, if possible, videotaped for the record.

The principal psychological factor contributing to a successful interrogation is privacy, being alone with the person under interrogation. In providing privacy during interrogations, it is advisable to select a quiet room with none of the usual police surroundings and with no distractions within the subject's view.

In cases where a suspect has given an alibi, it should be checked if at all possible before the interview begins. Any known inconsistencies in the alibi will assist the officer. Moreover, an alibi check may actually establish the innocence of the suspect. However, many other circumstances may point to his/her guilt. A background check should be done before the interview to determine if there are any prior arrests for crimes of a similar nature. The number of times he/she has moved or the number of jobs the suspect has held may point toward the fact that in prior communities and in prior places of employment there was some problem that might have stemmed from the individual's sexual preference.

The officer should avoid creating the impression that he/she is an investigator seeking a confession or conviction. It is far better to appear in the role of one who is seeking the truth. The neutrality of this position will give the investigator an advantage and may lull the suspect into being overconfident.

The interrogator should dress in civilian clothes rather than in uniform during an interrogation. Otherwise, the subject will have before him/her a constant reminder of police custody and the possible consequences of an incriminating disclosure. The investigator should avoid inflammatory words or expressions such as "rape," "pornography," "abuse," and "confess your crime." It is much more desirable, from a psychological standpoint, to employ milder terminology like "touch," "caress," and "tell the truth." The investigator should keep in mind that some offenders do not view their activities with children as criminal. They may not regard the fondling of children as a criminal assault, and they may not regard the photographs of children in the nude or engaged in sexual activity as pornography. The investigator should maintain and use nonjudgmental language.

A subject should be treated with decency and respect, regardless of the nature of his/her offense. This behavior on the part of the interviewer may well be the turning point of the interrogation and may make the suspect feel comfortable enough with the interrogator to give a full confession and, in fact, admit to crimes of which the interviewer had no prior knowledge. It has been noted by a number of investigators that once a child molester begins talking, he/she frequently details each and every episode of sexual assault that the offender can remember. A sympathetic, understanding attitude in an interrogation is far more effective than a threatening approach.

Because of the coercion issue, the interviewer should avoid, at any time during the interview, making any promises to the offender about the possible effect a confession would have on the prosecution of the case. To promise an offender anything at this time, including probation or a diversionary treatment program, is promising something the law enforcement officer cannot carry out. If the offender stands by his/her constitutional rights not to make a statement and the investigator then advises the offender that he/she will not be considered for diversion or treatment programs if he/she does not confess and he/she subsequently confesses, this confession may well be held as having been coerced and be considered inadmissible in a court hearing. Therefore, the investigator should work hard to establish rapport with the offender so that the offender wants to try and please or brag to the investigator about the activity.

In dealing with a suspect whose guilt is definite or reasonably certain, the interrogator will usually disclose his/her belief in the suspect's guilt and attempt from the onset to secure a confession or incriminating statement. If the interview with the child was videotaped, it might be useful to show the offender all or part of the tape. In some instances, this has persuaded offenders to make a full confession.

During the interview with the suspect, investigators should:

  • Display an attitude of confidence in the subject's guilt.

  • Point out some, but by no means all, of the circumstantial evidence indicative of the subject's guilt.

  • Sympathize with the subject by telling him/her that anyone else might have done the same thing under similar circumstances.

  • Reduce the subject's guilt feelings by minimizing the seriousness of the offense. It is also helpful to tell the subject that the interrogator has heard many people tell about sexual activities far worse than any the subject can relate. The conduct itself should be discussed as though it were actually normal.

  • Suggest a less revolting and more acceptable motivation or reason for the offense than that which is known or presumed. An offender should always be offered an opportunity to save face by letting him/her base the initial admission of guilt upon a motivation or reason for the act. To secure the initial admission of guilt, the interrogator should suggest such possible reasons, motives, or excuses. The important point is to have the subject place him/herself at the scene or to connect him/herself with the event in some way. Following a partial admission, the interrogator can then point out that the circumstantial evidence negates certain explanations. The inconsistency between the subject's original denial of the crime and his/her present admission will deprive him/her of a possible defense.

  • Remember, the main objective of the interview in many instances is to have the subject place him/herself at the scene or in contact with the victim.

  • Display understanding and sympathy because it may urge the subject to tell the truth. Urge the subject to tell the truth for the sake of his/her own conscience, mental relief, or moral well-being as well as for the sake of everybody concerned, and also because it is the only decent, honorable thing to do.

  • Seek an admission of lying about some incidental aspect of the occurrence. Once a subject has been caught in a lie about some incidental detail, he/she loses a great deal of ground. As he/she tries to convince the interrogator he/she is telling the truth, he/she can always be politely reminded that he/she was not telling the truth just a short while ago.

  • Ask the subject a question regarding some detail of the offense rather than seek a general admission of guilt; getting an admission on seemingly insignificant details will sometimes lead the accused into a confession.22

Mental Health Information

As with medical findings, the opinions of mental health professionals will sometimes be introduced into child abuse investigations. Extreme caution should be exercised when mental health professionals are called upon to offer an opinion about whether this child was abused by this perpetrator, particularly if based on the assessment of the alleged offender. Various psychological tests and/or clinical interviews by a trained professional may yield information about the individual's predisposition to commit abuse or factors which may contribute to abuse, such as a history of victimization, immaturity, sexual arousal toward children, a tendency toward violence, or a loss of self-control. (It should be recognized that defense expert witnesses may argue that the lack of such known risk factors makes the individual innocent of any criminal charges.) Both arguments overstate the role of the mental health professional. The time for such input is when sentences are being determined, when the court is considering incarceration versus community-based alternatives.

While not appropriate evidence, the insight of mental health professionals can be helpful in child maltreatment investigations. Mental health therapists can best assess the impact of the abuse and the investigation on the child. They can provide insight into the ability of the child to testify and explain the developmental reasons for a child's actions. Their clinical training may help determine the credibility of a child's statements or how the investigator should proceed in interviewing the principals involved. State child abuse statutes abrogate professional privileges of confidentiality. Consequently, mental health professionals must share relevant information regarding a particular case.
