Forensic Files

In 1986, Gary Dale Larson was stabbed to death in his Edmond, Oklahoma home and then the killer sexually assaulted Larson's girlfriend Janet Haynes. Hayne's story seemed farfetched: The perpetrator was wearing only underwear and gloves broke into the house, stabbed Larson to death, then raped and terrorized her for hours afterwards. But, the evidence at the scene supported her story, and investigators turned for help to the FBI and their criminal profilers. The case remained cold until 2004, when Jonathan Scott Graham was arrested in the same neighborhood where Larson was murdered and footprint and DNA analysis placed Graham at the scene of the murder.
