Henry Lee Lucas confessed to Adam's murder, but he later recanted his confession. He stated that Adam's body would never be found. I don't know if I believe that Lucas was the killer or not, but the Walshes do. Lucas never served time for Adam's murder. The man confessed to many murders across the U.S.; he traveled with a mentally-challenged man named Otis O'Toole. Lucas confessed to many heinous crimes, including murder, rape, and cannibalism. Who knows what was the truth and what were lies. He was a psychopath. I'm pretty sure he's dead now, and good riddance. I do wish the Walshes had gotten definate closure on their son's murder, though.
Sorry I don't have any links for this information. I'm at my computer at work and can't access a lot of places.
