What is the recommended action for a glass with a visible bloody handprint at a crime scene?

• A. Leave it at scene
• B. Photograph only
• C. Transport to lab for analysis
• D. Store in evidence locker

Answer: (C)

Biological evidence needs careful collection and lab analysis to preserve DNA and other trace information. A glass with a visible bloody handprint is a potential DNA source, so the best action is to have it collected and sent to a forensic laboratory for analysis. This ensures the sample is protected from contamination, properly packaged, and documented so its integrity and chain of custody are maintained. While photographing the item and scene is important for documentation, it cannot substitute for actual lab testing. Leaving the glass at the scene or simply storing it without proper collection risks loss or contamination of valuable evidence.
