Forensic Leech Solves Oz Case
Eight years ago Peter Cannon tied up a 71 year old woman in her remote Tasmanian home and stole several hundred dollars in cash. Unbeknownst to Cannon, a terrestrial leech (probably Philaemon grandis, endemic to the island) that had finished feeding on him, dropped off while he was in the midst of theiving.
The case remained unsolved until forensic experts extracted DNA from the leech gut contents, and matched fingerprinting profiles to those on record for Cannon. Cannon promptly plead guilty when faced with the incriminating match.
