The Municipal Police Institute, Inc. (MPI) is a private, nonprofit charitable affiliate of the
Massachusetts Chiefs of Police Association. MPI provides training and model policies and
procedures for police agencies. This policy is an edited version of MPI Policy 2.07 “Sexual
Assault Investigations.”
GENERAL CONSIDERATIONS AND GUIDELINES
Sexual assaults are one of the most difficult crimes that police officers are called
upon to investigate. It is imperative that officers involved in this type of investigation
show the utmost compassion for the victim as well as possess an understanding of the
trauma the victim may have endured. An investigator possessing the delicate balance
of patience with and sympathy for a victim will be more apt to solicit the cooperation
needed from a victim necessary to successfully prosecute this crime. A skillful and
professional interview can provide the information necessary to apprehend the suspect
and the evidence necessary to obtain a subsequent conviction.
Officers should be knowledgeable of the "first complaint" exception to the
“hearsay” rule and its importance in rape and other sexual assault cases. The first
person told of a sexual assault by the victim may testify in court to the statements
concerning the sexual assault made to that person by the victim as well as why the
statements were made at that particular time.i
Because police officers and investigators often qualify as "first complaint"
witnesses, it is especially important for them to document every detail of the victim's
account of the attack so that the officer or investigator will be able to testify accurately
and effectively at any subsequent court proceeding. Qualified sexual assault
counselors, may not disclose certain information without written authorization from the
victim.ii

Policy & Procedure Page 2 of 8
It is the Policy of the Lexington Police Department in responding to the report of a
sexual assault to:
Minimize the traumatic experience suffered by the victim;
Thoroughly investigate, with the goal of a speedy apprehension and ultimate
conviction of the assailant;
Reduce the opportunity for the crime of sexual assault to occur by educating the
public in preventive measures (See Department policy 45A – Crime
Prevention);
Cooperate with local social service agencies, hospital personnel and community
groups in sexual assault prevention programs; and
Impress upon the public that the role of the police in investigating reports of
sexual assaults or attempted sexual assaults is to provide a professional
response.
DEFINITIONS
Rape: Sexual intercourse or unnatural sexual intercourse by force or threat of
force against the will of the victim.iii
Sexual intercourse: penetration of the victim, regardless of degree.
Statutory Rape: Sexual intercourse or unnatural sexual intercourse with a person
under the age of sixteen. No person under the age of sixteen is legally capable of
consenting to sexual intercourse.iv
Unnatural Sexual Intercourse: Oral or anal intercourse.
First Complaint: An exception to the hearsay rule, which may be applied only in
sexual assault cases.v
1. This doctrine replaces the “fresh complaint” exception.
2. The first person told by the victim of an alleged sexual assault may testify
about the fact of the “first complaint” and the circumstances surrounding
the making of that first complaint including:
a. Observations of the victim during the complaint;
b. Events or conversations that culminated in the complaint;
c. Timing of the complaint;
d. Other relevant conditions that might help a jury assess the veracity of
the victim’s allegations or assess specific defense theories as to why
the complainant may be making a false allegation.
3. Testimony from additional complaint witnesses is not admissible. There
may only be one First Complaint witness.

Policy & Procedure Page 3 of 8
PROCEDURES
A. Preliminary Investigation
1. Introduction
a. The first officer at the scene of a reported sexual assault shall:
i. Identify himself/herself as a police officer by name and rank;
ii. Express concern for the well-being of the victim;
iii. Obtain/render any necessary medical attention; and
iv. Be careful of word usage - do not use words or phrases that could
add to the victim's emotional state.
b. A sexual assault victim is often in a state of shock or severe
emotional distress requiring sympathetic attention.
c. Victim interviews shall be conducted by an officer who is trained and
certified to investigate sexual assaults (if such officer is available).
A victim of sexual assault who is male shall, whenever possible, be
initially interviewed by a male officer. Likewise, a victim of sexual
assault who is a female shall, whenever possible, be initially
interviewed by a female officer.vi
i. Keeping in mind the First Complaint witness rule, it may be best
to advise the victim that the Department has specially trained
officers to conduct this type of interview. If immediate
examination is not necessary the victim may be given the option
of waiting until a sexual assault investigator is available to conduct
a detailed interview.
ii. Should the interview start before the arrival of a trained
investigator, the officer should seek to continue the interview until
the arrival of the investigator. The officer should then remain and
continue to take notes as additional questions are asked. The
officer is the First Complaint and should remain so he/she can
fully document the interview.
iii. Employees answering the phone or tending to walk-in customers
in the lobby should ask why the person has come to the lobby. If
told that it is a sexual assault, the employee should immediately
cease any questioning other than that of a first aid/first responder.
A qualified officer should be summonsed to begin an interview as
a potential First Complaint witness.
d. Depending on the severity of the act, the Commanding Officer
should immediately make notification to the following members of
the command staff:
i. Chief of Police
ii. Captain of Operation
