Physical evidence of a criminal sexual assault must be collected from the alleged victims person within 72 hours, though evidence can often be obtained from towels, sheets, clothes, etc. for much longer periods of time. If you believe you have been a victim of a criminal sexual assault, you should go to a medical facility capable of providing collection of medical/legal evidence in cases of sexual assault, and has specially trained staff to do so before washing yourself or your clothing. Anaheim Regional Medical Center (714-774-1450) is the only hospital in Orange County that performs Sexual Assault Exams. You can contactyour local law enforcement agency ora crisishot-line for assistance.Having the evidence collected in this manner will help keep all options available, but will not obligate you to any course of action. Collecting evidence can assist the authorities in pursuing criminal charges, should you decide later to exercise it. If you have changed clothing since the assault, bring the clothing you had on at the time of the assault with you to the hospital in a clean, sanitary container such as a clean paper grocery bag or wrapped in a clean sheet (plastic containers do not breathe, and may render evidence useless). If you have not changed clothes, bring a change of clothes with you to the hospital, if possible, as they will likely keep the clothes you are wearing as evidence.
