This was one of the standout segments for me. It concerned a Peru immigrant named Enrique Elizarbe, who was murdered in his workplace around Washington, D.C. in early 1985 by a coworker named Roland Wheeler. I think this was in a factory or plant or something. Roland had beat Enrique to death with a crowbar indoors, then tried to make it look like Enrique had been attacked outside and he tried to help him. What I am wondering was what was the possible motive here? It was interesting to learn how a tiny fleck of green paint and a nail in a boot solved the case. At the end, it had a close-up of a disturbing, angry picture of Roland Wheeler for what seemed like forever. Totally senseless crime.
