The clothing you wore at the time of the rape will be kept. I don't want to report the assault. Collecting evidence gives you the option of pressing charges later. Reporting the crime may be the last thing on your mind right now but an avenue you may wish to pursue later. The physical evidence improves the possibility of conviction.
Evidence is lost with time.
Collecting evidence is best done within 12 to 18 hours after the assault. Samples of hair from your head and pubic area will be collected as well as material from under your fingernails. Procedures will be explained to you, step by step. Tests for gonorrhea and syphilis are routinely done. Medication will be offered to you to protect against the risk of these diseases.
