Documenting the Co-Ed Killer case

Month: February 2023

“He would notice a girl and really stare, not just look or glance.”

Susan Swanson, Ed Kemper’s older sister

Ed Kemper and his older sister Susan Swanson discussed the Santa Cruz murders and Herbert Mullin in April 1973 before Kemper’s arrest: “Guy [Kemper’s nickname] and I discussed them one day when mom and I went to the university to borrow a movie projector so I could show a movie I had brought from home [in Montana]. There was something said about Mullin firing his attorney because he had long hair, and I asked Guy if he thought Mullin had done the co-ed slayings too. He said he didn’t because none of them were similar in any way to how his victims had been shot–then the subject was dropped. The first weekend I was there, Guy went to Turlock and picked up [Kemper’s fiancée] and brought her to mom’s. We went to San Francisco that weekend Mom, I, [Kemper’s fiancée], and Guy, and along the road he mentioned that down there, pointing to the right, was where they had found two girls propped up against something I don’t remember the exact area. We drove along the coast highway, but this was a hilly section inland, just a bit. I believe it was just south of San Jose. Another time, I commented on the girls hitchhiking and mentioned they weren’t too bright, considering what happened and the particular ones I mentioned were really dressed shabby. He said it was strange because some of the co-eds killed were very attractive girls, not hippie looking at all. I think this was mentioned at the same time the conversation about Mullin was discussed on the way to the university. The subject changed. He didn’t say or do anything strange or comment any more than anyone might comment because of what had been happening.”

“One day when we were driving from Aptos along the beach toward Santa Cruz, just sightseeing, [Kemper] pointed off toward the beach and mentioned that a girl’s head was washed up along there -no more was said, and he brought it up.”

“Several times while we were riding around while I was there he would notice a girl and really stare, not just look or glance, and I teased him that he’d better get out of that habit when he gets married or [Kemper’s fiancée] would sure get jealous. He said she’s used to it or something along that line and most of these girls were dark skinned, possibly Mexican heritage, with black hair and medium build, tending toward heavy. He also commented that he sure likes those big butts- again I just passed it off and went on to other talk.”

“As far back as I can remember, Guy has wanted to be by himself.”

When Ed Kemper was arrested in August 1964 after murdering his grandparents, his mother, Clarnell Strandberg, and his older sister, Susan Swanson, were interviewed by doctors and social workers from the Atascadero State Hospital where Kemper was imprisoned for the next five years.

Clarnell Strandberg: “She [Kemper’s older sister, Susan] was always responsible for and protective of Guy [Kemper’s nickname] while I worked. Sometimes protected him from my discipline out of misguided love. He and Sue were close until she began to mature and then Allyn, my fourteen-year-old daughter and he had a close relationship-however his needs were building and hers were normal and gregarious and outgoing and she had friends he resented.”

Susan Swanson: “As far back as I can remember, Guy has wanted to be by himself, he has seemed to be happier when there was only family. He never seemed too interested in participating in activities with other children. We seemed fairly close at times, but if something didn’t go Guy’s way he would get awfully mad, not as if he were spoiled and throwing a tantrum but mad at everyone… All kinds of things would bother him, like the way my kids would cry or when my little girl would be drooling or spitting I would never hear the end of it from Guy. Sounds of a constant coughing or crying or heavy breathing would really upset him.”

“I missed all this by forty hours.”

Susan Swanson

Some time in March 1973, Ed [Guy] Kemper and his mother went off-roading in a jeep and Clarnell injured her shoulder. Kemper’s sister, Susan Swanson, came and stayed with Kemper and his mother on April 1:

“A little vacation and also it would be a good time to go down and help mom with her stuff that she couldn’t handle with her broken shoulder. So, it was kind of a two-way visit. So, I went down the first of April and I came home on the 19th. In fact, I missed all this by forty hours, which was very shattering to me. It was a beautiful nineteen days. [Kemper killed his mother on April 21st]. During the days, Guy would sleep an awful lot, he would get up maybe at noon or two o’clock. Either that, or I understood him to be going off with friends during the day, like target practicing or something. He might leave oh, around noon or something and come back around dinner time or whatever. Some days, he’d just kind of hang around the house or be gone for a couple of hours and then he and I would do things during the day. I would take mom to school to work and then I’d come back and kind of clean up the apartment while Guy was asleep and then when he’d wake up we’d either go do something or he’d go do something and I would just, you know, drive around or sightsee, or whatever. In the evening, I would pick mom up from school and Guy most always was gone in the evening. He would go to the Jury Room a lot or go to the show, or… as far as the accuracy, whether he was really there or not, I don’t know; but he was gone in the evenings a lot, and would get home quite late- two or three in the morning. And he drank quite a bit, of beer. For breakfast, he had two large cans of beer and he seemed to be able to hold beer quite well. I mean, it would take quite a bit before you would notice any signs that he had been drinking. I never saw him drunk. I never saw him staggering. I never saw him slurring his speech or anything.

“I’ve never taken lessons in judo or karate, but I have picked up a few little things, I’m fascinated with the tournaments, watching the art. I wanted to show [Kemper] this new throw that I had just picked up on television. Well, being 6’9″, or whatever, I’m 6’1″, or 6’1/2” myself, and not any weakling, and I was going to show him how the throw goes and I couldn’t even waver him on his feet and he says, he’s standing there with his hands on his hips saying, “What are you doing? What are you trying to do?”

“I said, “Oh, I’m going to throw you.” You know. We clowned around and made little fake karate chops and say, if I came around a corner or something and he was coming around at the same time, kind of like a surprise, not to surprise each other, but just bumping into each other coming around the corner, we’d go POW POW, and a few little phony karate things and the most scary thing right now is he would make a motion like he, with his hands in a karate chop, had lapped off my head and then held his hands out like he caught it. And laughed. And I would laugh. Because it seemed so funny, you know, this karate business, ho ho, and we were just playing around with it all the time. And this motion especially now, just this WHAP, and make his hands like he’s catching my head–and I’d laugh. I can’t believe this now.”
