Kemper’s sexual achievement

Inv. Michael Aluffi:   Did you ever have any kind of a sexual achievement while you were killing them [his victims]?

KemperYes, I’m sure it’s happened before, but the only time I actually noticed an ejaculation was as I was killing Mrs. Hallett on Saturday night, as she was dying, it was a great physical effort on my part, very restraining, very difficult, much less difficult that I made it, I went into a full complete physical spasm let’s say. I just completely put myself out on it and as she died, I felt myself reaching orgasm. In the other cases, the physical effort was less. I think with the Koo girl, in the case of a suffocation, the same thing happened. But I didn’t really notice it, because I did have sex with her right after causing her to be unconscious.

Ed Kemper mugshot – April 1973

This is probably one of the most famous pictures of Ed Kemper. This mugshot was taken on April 28, 1973, when he arrived in Santa Cruz, California, escorted by police after his arrest three days earlier in Pueblo, Colorado, where he had given himself up to local police, after the murders of his mother and her best friend.

Ed Kemper’s confession tapes

The prosecution yesterday rested its case against Edmund E. Kemper III. The state’s final evidence was a videotape showing Kemper’s lengthy confession of eight grisly murders. While the video confession was being played for the jury of six women and six men, Kemper buried his head in his hands.

His attorney, James Jackson, interrupted the proceedings to ask Judge Harry Brauer if Kemper could be excused. The judge agreed and Kemper was allowed to leave the courtroom.

Kemper’s confessions were introduced previously in the trial, but the video recording was shown to give the jury an impression of the defendant’s attitude while he was recounting the crimes for investigators last April 28, shortly after he surrendered in Colorado.
