Collecting Stains on the Victim
Procedures for collecting stains on the victim are:
- Use new sterile swabs (moistened with distilled water, if the stain is to dry) to swab the stain
- Allow swabs to air-dry
- Package in labeled paper
If the stain is dried in the hair, use new or sterile scissors to trim the strands of hair. Packaging should include documentation with reference points that explain the exact location of the stain on the victim.
