We know who but why?

Peter Gioe is one of those mystery victims. Other than he was an importer there is nothing else known about him. Somebody however, wanted him out of the way and succeeded in this quest back on this date in 1925. It appears that Peter was set up by somebody he knew because as he pulled up in front of a building and was getting out of his car, two men emerged from a doorway and shot him in the head killing him.
