The Livingston County Sheriff's department is re-opening a 29-year-old cold case.  Robert and Marcia Edwards were found shot in the head in their rural Pontiac home in 1983.  Sheriff Marty Meredith hopes updated technology can help them catch the couple's adopted son, who was accused of the murders.

Joe Edwards hasn't been seen since the murders but Meredith says they've gotten a DNA sample from one of his immediate family members.  They hope the DNA helps them find a match.  Edwards would be 47-years-old.  The case was featured on the TV show "America's Most Wanted" three times between 1988 and 1998.  Anyone with information on the case should call the sheriff's department at 815-844-2774.
