YORK, S.C. (AP) -- Investigators are still looking for a second suspect in the killing of a 79-year-old lawyer a year after he was found dead outside his York home.
Authorities say Melvin Roberts was beaten in the head a year ago Friday, then strangled to death by someone who tightened a zip-tie around his neck.
York Police Chief Andy Robinson told The Herald of Rock Hill that his detectives spend a couple of hours a week following leads in the case.
Roberts' girlfriend has been charged with murder and is awaiting trial.
But prosecutors say evidence at the scene pointed to someone else helping. Footprints were found heading into the woods behind Roberts' home and DNA on the zip-tie doesn't match Roberts, his girlfriend or 50 other suspects who have been tested.
