A former Texas justice of the peace convicted of theft says he voluntarily submitted to a gun residue test as part of the investigation into the weekend killings of a Texas prosecutor and his wife.
Eric Williams said Wednesday he's cooperated with law enforcement and hopes authorities find who fatally shot Kaufman County District Attorney Mike McLelland and his wife, Cynthia. The couple's bodies were found in their home Saturday.
The slayings happened two months after assistant prosecutor Mike Hasse was gunned down outside the Kaufman County Courthouse.
Investigators haven't named any suspects in either case.
Williams says he has no hard feelings toward McLelland's office, which prosecuted Williams for theft last year. He says he understands authorities investigating the deaths need to conduct a thorough process of elimination.
