Lt. Nancy Alvarez of the Monroe County Sheriff's Office said Tuesday her investigators are trying to find medical examiner's records for Richard Sills. Sills was shot to death in the home he shared with his wife, Betty, in Big Coppitt, Fla. in 1965.
At the time, police said he died from a self-inflicted gunshot wound. Police said his wife was the only other person in the room.
His wife hasn't been charged with any crime in his death. But 76-year-old Betty Neumar was recently charged in North Carolina with trying to hire a hit man to kill another husband.
A telephone message left for Neumar's attorney was not returned.
