Crime Scene Investigation: applications of DNA Forensics

    In this investigation, several patches of bloody snow was found near the last sighting of a person who disappeared and subsequently was determined to have been murdered. DNA testing showed that the blood stains were not human, but rather from a moose (left) and an otter (right).

    Commerical forensic testing of questioned animal products is available from "The Helix & Primer" DNA Sequencing Service at Memorial University.
