Around 1965 I was a young patrolman working the midnight shift, and we began finding bodies, 5 in all, spaced over a period of two or three months, all had been murdered and dropped off in the same area. All had been strangled, but the medical examiner said that before they died the killer had played tic tac toe on their bodies with a sharp knife. All the victims were what in those days we called "smokehounds", or bums, today they are called homeless. Evidently the killer was picking them up, taking them somewhere, and killing them after torturing them, and then dropping them off. We never got close to solving the case.
