What is the recommended method for collecting rape evidence?

• A. All clothing should be removed and placed in a single plastic bag.
• B. Only blood-stained items should be collected.
• C. Clothing should be left on the body and not bagged.
• D. All outer and undergarments must be removed and packaged separately in paper bags.

Answer: (D)

Proper collection of clothing in sexual assault evidence focuses on preserving trace materials and preventing contamination. The best approach is to remove all outer and undergarments and package each item separately in paper bags. Removing every garment ensures that any trace evidence on the fabric—fibers, semen, saliva, skin cells—can be captured, not overlooked by leaving items on the body. Packaging each item separately prevents cross-contamination between garments and preserves the integrity of the evidence for analysis. Paper bags are preferred over plastic because they allow moisture to evaporate, reducing the risk of mold and DNA degradation; they also help keep items dry and clearly separated, which is important for accurate testing and maintaining the chain of custody. In practice, the clothing should be labeled, placed in separate bags, and handled with care to avoid altering any potential evidence.
