 GRAFTON, Ohio -- A con for almost as long as he was a cop, former Mansfield police Lt. Charles Oswalt broke his silence on the eve of a decision on his freedom. He flatly denied responsibility for one of the area s most notorious killings. "I didn t commit the crime, so I m not going to admit to it. I can t show remorse for a crime I did not commit," Oswalt said in an exclusive interview with the News Journal on Wednesday at Grafton Correctional Institution. It s the first time he has talked publicly about the killing since taking the stand in his aggravated murder trial in June 1988. Oswalt, 59, was to be released from prison Monday after serving more than 15 years for the 1988 death of Margie Coffey, 32, of Butler. He was sentenced to 10 to 25 years in prison on charges of voluntary manslaughter and abuse of a corpse. He successfully appealed a 1998 parole decision requiring he serve another 10 years, leading to a June hearing to consider his release. Psychic Kathlyn Rhea has worked extensively with law enforcement around the world, and her accuracy has been well documented. Her clues led police to the murdered body of Margie Coffey.
