Collection Procedures for a Sexual Assault Case
Procedures for collecting DNA evidence from a sexual assault case:
- If the assault occurred on a bed, collect the top surface of bed linen, which may hold stains, hairs, or fibers.
- If wet stains are visible, use a permanent marker to discretely mark the location of the wet stain and document your actions.
- Package evidence in paper to promote drying, but take care to avoid folding garments together to prevent the inadvertent transfer of stains to unstained portions of the garment.
