Thank you, Mad Men, for this:
From Wikipedia:
Richard Franklin Speck (December 6, 1941 – December 5, 1991) was a mass murderer who systematically tortured, raped, and murdered eight student nurses from South Chicago Community Hospital on July 14, 1966.
And, this:
In May 1996, Chicago television news anchor Bill Kurtis received video tapes made at Stateville Prison in 1988 from an anonymous attorney. Showing them publicly for the first time before a shocked and deeply angry Illinois state legislature, Kurtis pointed out the explicit scenes of sex, drug use, and money being passed around by prisoners, who seemingly had no fear of being caught; in the center of it all was Speck, performing oral sex on another inmate, sharing a huge pile of cocaine with an inmate, parading in silk panties, sporting female-like breasts (allegedly grown using smuggled hormone treatments), and boasting, “If they only knew how much fun I was having, they’d turn me loose.” The Illinois legislature packed the auditorium to view the two-hour video, but stopped the screening when the film showed Speck performing oral sex on another man.
From behind the camera, a prisoner asked Speck why he killed the nurses. Speck shrugged and jokingly said, “It just wasn’t their night.” Asked how he felt about himself in the years since, he said, “Like I always felt … had no feeling. If you’re asking me if I felt sorry, no.” He also described in detail the experience of strangling someone: “It’s not like TV … it takes over three minutes and you have to have a lot of strength.” John Schmale, the brother of one of the murdered student nurses, said, “It was a very painful experience watching him tell about how he killed my sister.”
Portions of the tapes were later broadcast on the A&E Network’s Investigative Reports. The same airing of Investigative Reports included interviews with people who believed Speck was not taking hormones, wearing panties, etc. voluntarily, and he’d instead been forced to by other inmates — this may have been his way of surviving his time in prison.
