Forensic Files

Purr-fect Match (7x7)

Air date: Feb 12, 2002

A woman vanished from her home on Prince Edward Island. Her abandoned car was found in a field; inside, the windows were spattered with blood. During the search for her body, police found a plastic bag containing a pair of sneakers and a bloody leather jacket. On the jacket were white hairs that investigators discovered had come from a cat. Forensic testing on a cat had never been done before anywhere in the world. This case made history: It was the first time that animal DNA was used to solve a crime.
