A Dekalb County Alabama man who was a suspect in the death of his first wife, and also in the disappearance of his second wife and her eleven year old daughter, has been sentenced to a prison term of 10 years on a weapons charge. U.S. District Judge Sharon Blackburn handed down the maximum prison term possible after hearing testimony that 39 year old Barry Whitton told a fellow jail inmate that he had killed three people in the past, and threatened to kill many more. Whitton pleaded guilty last September to a federal charge of being a Felon in Possession of Firearms, but he hasn’t been charged in his first wife`s death, or with the disappearance of his second wife and step-daughter. Investigators found a total of five firearms while searching Whitton`s home in connection with those disappearances. Whitton was a suspect in the death of his first wife, Michelle, and in the disappearance of his second wife, Kimberly, and step-daughter, Haleigh Culwell, who have been missing since June 21st of 2007.
