I am an old guy who has been fascinated by serial killers from the 40's on. One of them said from jail, I think the guy from Santa Clara, "Don't start; you won't be able to stop." And he talked about enjoying his time in jail reliving the experiences. Ken Hansen who killed the three boys in Chicago in 1955 and maybe the two sisters a month later, was caught 40 years later because he bragged to a friend about the killings. The boys, 11-13 were naked, strangled abused and discarded a day and a half after they were killed. The examining police found that there was a pedophile ring or club in the area. Do you think he might have been selling time with them? One guy killed a girl a half block from where we lived and we had two young daughters. We were terrified. It had been so easy to do.
