Rape Kit
In a sexual-assault case, forensics technicians collect evidence from the most intimate parts of a survivor’s body. Assembling a rape kit involves a head-to-toe exam and includes swabs of any place the perpetrator may have left DNA in the form of semen, saliva, hair or skin cells. The victim is also extensively photographed and interviewed. The entire process can take up to four hours.   Brent Humphreys for TIME
