Speck was one sick puppy. His was as crime of criminal insanity. He was just a garden variety sociopath. Un-succesful in his dealiings with family, life, career, etc.
He was a loser and he projected his unhappiness upon those unfortunate enough to be around him:
"...At 11:00 PM on July 13, 1966, Speck broke into a townhouse located at 2319 East 100th Street in the Jeffery Manor neighborhood of Chicago. It was functioning as a dormitory for several young student nurses, some of whom were Filipinos. Armed with only a knife (the Illinois Supreme Court opinion recounting the facts of the case reports that the defendant appeared at the door of the townhouse holding a gun<5>) — he raped then killed the young women, including Gloria Davy, Patricia Matusek, Nina Schmale, Pamela Wilkening, Suzanne Farris, Mary Ann Jordan, Merlita Gargullo, and Valentina Pasion. Speck, who later claimed he was high on both alcohol and drugs, may have originally planned to commit a routine burglary.<6> Speck held the women in the house for hours, methodically leading them out of the room one by one, stabbing or strangling them to death, then finally raping and strangling his last victim, Gloria Davy. Only one woman, Cora (Corazon) Amurao, escaped because she managed to wiggle under a bed while Speck was out of the room with one of his victims. Speck may have lost count, or he may have known there were eight women living in the townhouse but had been unaware that a ninth student nurse was spending the night there. Amurao stayed hidden until almost 6 AM. When she emerged, she climbed out of her northeast bedroom window onto a ledge screaming, "They're all dead! All my friends are dead!..."<7>
"...Speck customarily refused all media requests, but granted one prison interview to Bob Greene in 1978; Speck told Greene that he read Greene's column in the Chicago Tribune. In this interview, Speck confessed to the murders for the first time publicly and said he thought he would get out of prison "between now and the year 2000," at which time he hoped to run his own grocery store business.<10> He told Greene that one of his pleasures in prison was "getting high."<10> When Greene asked him if he compared himself to celebrity killers like John Dillinger, Speck replied, "Me, I'm not like Dillinger or anybody else. I'm freakish."<10>
Speck said that when he killed the nurses he "had no feelings," but things had changed: "I had no feelings at all that night. They said there was blood all over the place. I can't remember. It felt like nothing... I'm sorry as hell. For those girls, and for their families, and for me. If I had to do it over again, it would be a simple house burglary."<10>
Speck's "final thought for the American people" was: "Just tell 'em to keep up their hatred for me. I know it keeps up their morale. And I don't know what I'd do without it..."
http://en.wikipedia.org/wiki/Richard_SpeckHe was a sick fucker and once inside became an even sicker psychopath. Please go to the Wiki page I linked and read what they were up to in the joint, if you can stand it.
We in Wisconsin had absorbed the Ed Gein murders and thought nothing could be that bad. We only had to wait a few years to witness Speck's insanity.
