Question

At the scene of the crime, the evidence collector found a damp, bloody shirt. the evidence collector quickly wrapped the shirt in a paper bindle. he inserted the paper bindle with the shirt into an evidence bag. the bag was sealed with tape, and the collector wrote his name across the tape. the csi also picked up three cigarette butts and put them into a plastic evidence bag, which he sealed and labeled. an evidence collection log was completed and taped to each of the evidence bags. what did he do incorrectly?

Answer 1

The evidence collector stored the three cigarette butts together as the same piece of evidence. All evidence is supposed to be stored separately to prevent cross contamination of any DNA evidence it might contain. Each cigarette butt should have gotten its own evidence bag.
