Morrow County prosecutors say their investigation into a man's murder is not over, even after the killer pleaded guilty. They're giving another look to Joseph Rosella's beating death after Cory Kelly claimed he killed the man on the orders of Rosella's wife. Kelly made the statement yesterday before he was sentenced to 14 years in prison on voluntary manslaughter charges. Prosecutors say Rosella's wife has been a person of interest from the beginning.
