DNA testing can prove innocence … it can also prove guilt. Test results confirm Kenneth Charron’s DNA matches the DNA investigators recovered from the home of a deaf St. Louis woman who was raped in 1985. Charron is already serving a life sentence for raping and robbing the victim. He was convicted in 1986 on the testimony of the victim and her mother, who both identified Charron in photos and in line-ups. His challenge of his conviction was backed by the New York-based Innocence Project, which uses DNA testing in a bid to free those who have been wrongfully convicted. Prosecutors say this DNA evidence proves Charron is a rapist and a liar.
