- Suspect Rape Kit: performed by crime scene officer or investigating officer, seized and conveyed to crime lab; contains 7 envelopes for packaging evidence, goal is to find trace evidence deposited by the victim

- Interviews should be professional and complete, while being sensitive to the victim's emotional and mental state
-
Best Way to Identify Evidence at Crime Scene:
- Have the victim remain at the crime scene if no medical emergency
- If a medical emergency exists, have the victim conveyed to the hospital
- Attempt to interview the victim to determine any items that need to be secured as evidence

-
Process for Locating Evidence:
- Residential structures and other buildings: walk around the entire structure, locate point of entry and exit, and look for property or items belonging to the victim or suspect
- Vehicles: entire vehicle and area around the vehicle is a crime scene, look for evidence around the vehicle
- Outside areas: have the victim point out the area where the assault occurred, rope off the area, and search extensively
-
Reasons for a Complete and Thorough Report:
- For the benefit of follow-up investigators
- Facts documented for future use
