Here's an absolutely infuriating story from Radley Balko. He has uncovered some deeply disturbing video of forensic scientist Michael West using a dental mold to place bite marks on a 23-month old corpse.
Those bite marks were then used to positively "identify" her alleged killer - who is now on death row. They were the only physical evidence linking him to the killing.
This wasn't the only time West "found" bite marks during autopsy that other examiners "missed."
In fact, this is probably only the tip of the iceberg. This video was taken in 1993, and both West and the other examiner involved are still practicing today. In the article, Radley Balko casts some more light on the horrifying records of these two men.
