Ed was found guilty of involuntary manslaughter, but was also deemed mentally ill, in the March 1993 murder of his wife. According to state police in Meadville...Mary Gingerich was last seen with family members including her father. But investigators also say the circumstances in this case remain unclear and custody is an "unresolved issue."
