After Ed Kemper was imprisoned for life in 1973, some crime magazines published articles revisiting Kemper’s case in the late 1970s and early 1980s. These articles portrayed Kemper as a serial killer who used a power saw or a buzz saw to murder his victims, which is far from the truth. But a bit of research revealed that there is a link to the use of saws in Cindy Schall’s murder case: after finding the different parts of her body in different locations in and around Santa Cruz, police and a pathologist determined she had been sawed into pieces with a power saw.
Ed Kemper mainly used firearms, knives and strangulation as his murder weapons.
He shot to death both his paternal grandparents, Maude Matilda (Hughey) Kemper and Edmund Emil Kemper Sr. on their ranch on August 27, 1964 with a rifle given to him by his grandfather. Kemper also stabbed his grandmother post-mortem.
Mary Ann Pesce and Anita Luchessa were both murdered by Kemper on May 7, 1972. Pesce was stabbed with a knife and strangled to death in the backseat of Kemper’s car. Luchessa was killed in the trunk of the car in a similar manner.
Aiko Koo was choked to death by Kemper on the evening of September 14, 1972 right next to his car on a secluded road. He also raped her while she was unconscious.
Cindy Schall was fatally shot in the head by Kemper with a .22 caliber pistol in the trunk of his car on January 7, 1973.
On February 5, 1973, Kemper first fatally shot Rosalind Thorpe in the head and then Alice Liu with his pistol in his car while driving on the UCSC campus. Kemper shot Liu several times, including twice in the head.
In the early hours on April 20, 1973, Kemper snuck into his mother Clarnell Strandberg’s bedroom to bludgeon her with a claw hammer and slit her throat with a penknife.
On the evening of April 20, 1973, Kemper murdered his mother’s best friend, Sally Hallett, by strangling her to death with his arm in his mother’s apartment.

Ed Kemper’s paternal grandparents: Edmund Kemper Sr. and Maude Hughey Kemper
Edmund Emil Kemper Sr. and his wife Maude Matilda Kemper were both murdered by their grandson, serial killer Edmund Kemper III, on August 27, 1964, at their ranch in North Fork, California. They were his first victims.
Maude Matilda (nee Hughey) Kemper was born on November 19, 1897 in Topeka, Shawnee County, in Kansas. She was the sixth of seven children to her parents Henry McClellan Hughey and Violet Elizabeth (nee Dodge) Hughey. Her family moved to Los Angeles in 1910.
That’s where she met Edmund Emil Kemper Sr. a few years later, and married him on June 7, 1914. She was 16 and he was 21. They had three sons: Edmund Emil Kemper Jr. (1919-1985); Robert (1921-2018); and a third son whose name might be Raymond.
Edmund Sr. was a farmer before enlisting in the Army in 1917, and serving during the First World War. He was the third of six sons to his parents Frederick Augustus Reinhardt Kemper and Bertha Anna Haas. After the war, he worked as an electrician for the California State Division of Highways.
Maude and Edmund Sr. lived on an isolated farm in North Fork, Madera County, California, in 1963, when their oldest son, Edmund Jr., visited them with his second wife and his son Edmund III during the Christmas holidays. After the celebrations, Edmund Jr. left his son with his parents. Edmund Jr. explained his decision in 1964:
“His personality had changed so much that I was worried about him being here with my present wife, who tried very hard to be a real friend to him. I saw him one day in a brooding mood and his eyes looked like a sleepwalker. In several talks I had with him toward the last he seemed fascinated by death and war. Tried to watch Weird Tales on TV which I suppressed.”
Of his father, Kemper said, “he didn’t want me around, because I upset his second wife. Before I went to Atascadero, my presence gave her migraine headaches; when I came out she was going to have a heart attack if I came around.”
It was because of that, Kemper said, that he was “shipped off” to his paternal grandparents to live in “complete isolation” on a California mountain top with “my senile grandfather” and “my grandmother who thought she had more balls than any man and was constantly emasculating me and my grandfather to prove it. I couldn’t please her… It was like being in jail… I became a walking time bomb and I finally blew…”
Edmund Sr. and Maude’s ranch in North Fork at the time of the murders
Kemper hated living on his grandparents’ farm, but he had great admiration for his grandfather. Some people who knew Kemper believed his grandfather was the only person he ever really loved: “Well, I’d heard stories about when he [his grandfather] was younger. He was a pretty fierce guy. He was an original cowboy. He carried a .45 on his hip. He was a tough guy wrangler, and my father had told me that he back-handed him clear across the kitchen one night when he got, I guess, smart with him.”
As for his grandmother, she was a strong woman, who reminded Kemper of his own mother. She wouldn’t let him bring any friends home or get into any social activities in school. He couldn’t watch cartoons and she screened any TV shows he watched. Kemper said: “She had placed herself in the position of being, in essence, my warden. And she said if you ever want to go live with your father again, you had better do what I say.”
His grandfather bought in a .22 and taught him how to shoot it. Kemper spent hours in the bushes shooting at birds, gophers and other small animals to annoy his grandmother who didn’t want him killing animals. He disposed of the remains carefully. Edmund Sr. eventually took away the rifle at the behest of Maude, who didn’t see the point in killing things just for the sake of killing them. This punishment infuriated Kemper, as the weapon served as an outlet for his growing aggression.

Confined at home, Kemper’s anger started to simmer, and he began to transfer his hatred for his domineering mother to his domineering grandmother.
Kemper laughed as he recalled an incident with his grandmother when she left him home alone one day but took his grandfather’s .45 automatic with her in her purse, because she was afraid he might “play” around with it in her absence. His grandparents were going to Fresno on a monthly shopping trip. He recalled: “I saw her big black pocketbook bulging as she went out the door and I said to myself, ‘Why that old bitch, she’s taking the gun with her, because she doesn’t trust me, even though I promised I wouldn’t touch it.’” He said he looked in his grandfather’s bureau drawer and “sure enough the gun was gone from its usual place… I toyed with the idea of calling the chief of police in Fresno and telling him ‘there’s a little old lady walking around town with a forty-five in her purse and she’s planning a holdup’ and then give him my grandmother’s description. How do you suppose she would have talked herself out of that?”
Maude began to fear the grandson she had inherited. Possibly because she was the object of Kemper’s deadly glares, she sensed he was plotting against her.
Kemper’s mother, Clarnell Strandberg, reacted in 1964: “Pressure [on Kemper] must have been building. [Maude] wrote how happy he was with his gun and dog and ‘great authors and school’ and it wasn’t until the tragedy that I was told by the father that he was beginning to worry and frightened them with his moods. I wish I had known.”
On August 27, 1964, Kemper’s grandfather was running errands at the grocery store and the post office. His grandmother was working on a short story for Boy’s Life Magazine, “Fire in the Cannon,” in the kitchen. Kemper was sitting at the kitchen table with her. They started to argue after he stared at her with the horrifying expression she had observed before. Enraged, Kemper stormed off and retrieved the confiscated rifle that his grandfather had given him for hunting. He decided to go rabbit hunting and went outside to fetch is dog, Anka, on the porch. His grandmother uttered her last words: “Oh, you’d better not be shooting the birds again.” He stopped to look in through the screen window. He had fantasized about killing her before. She was facing away from him. He raised his rifle aimed at the back of her head, and fired through the screen. Maude slumped forward on the table where she’d been typing. He shot her twice in the head and once in the back. He then wrapped her head in a towel and dragged her body to the bedroom, went to get a knife and stabbed her three times so hard, the knife bent double: “I didn’t think she was dead and I didn’t want her to suffer any longer.”

His grandfather soon returned home and Kemper went outside to greet him. Edmund Sr. nodded, smiled and waved to his grandson as he began unloading food and supplies from the truck. Kemper returned the greeting and sneaked up closer to his grandfather: “When he turned, I placed the rifle about thirty inches from the back of his head and shot him. Kemper later explained that he didn’t want his grandfather to see what he had done to his wife of fifty years and that he would be angry with Kemper for what he’d done.
Kemper dragged is grandfather’s body to the garage and washed the blood from his hands with a garden hose. He also tried to clean the blood near the truck.

Back inside the house, Kemper had a passing thought about undressing his dead grandmother and exploring her body sexually to satisfy his carnal curiosity, but he shook it from his mind as being too perverted.
He was unsure of what to do next, so he phoned his mother, who told him to sit tight while she called the Madera County Sheriff. Kemper also called the police to make sure they would come. When the police arrived, Kemper was sitting calmly on the front porch. The reason he gave for his actions: “I just wanted to see what it felt like to shoot Grandma.”

From an unsigned note from a Social Worker at Atascadero State Hospital, a maximum-security facility that houses mentally ill convicts, where Ed Kemper was imprisoned for five and a half years after killing his paternal grandparents on August 27, 1964:
“In February 1964, ward’s [Kemper’s] mother was allegedly drunk when she called ward’s father in the middle of the night and told him that ward was “A real weirdo” and that he was taking a chance in having ward stay with his [parents] and that he might be surprised if he awoke some morning to learn that they had been killed.”

From a 1973 interview with Susan Swanson, Ed Kemper’s oldest sister, where she recalled his mood in 1964, after their father left him with his parents at their ranch in the mountains in North Fork, California:
“So, after that school year, while he was fifteen, he came home to Montana for summer vacations. I spent time with him, I was living back in Helena then, I was still married – in fact, I was three weeks away from having my third child. We spent a lot of time together. He seemed, oh, I don’t know, he was… He could have fun, he could laugh, he could play and be silly and visit and stuff like that, but deep down he seemed awfully hurt. Like you know, it really sunk in that his dad didn’t want him and this still intensified his love for his father. He just kept reaching and grabbing for him. So, we took him fishing and all kinds of things and then he went back down to Madera and it was just, oh, a matter of a couple of weeks later that he killed his grandparents.”

Sara “Sally” Taylor Hallett was Ed Kemper’s last victim. She was Kemper’s mother’s best friend and a colleague of Clarnell’s at UCSC. Born on October 19, 1913 in Washington, Hallett had two sons, Edward and Christopher Hallett. Kemper murdered Hallett in his mother’s apartment on Easter weekend in 1973. She was 59 years old.
After killing and decapitating his mother, Clarnell Strandberg, early on the Saturday morning before Easter, Ed Kemper spent much of the day drinking. That evening, he telephoned his mother’s close friend, Sara Taylor Hallett, saying he wanted to surprise his mother and take her and Ms. Hallett to dinner that night.
Kemper prepared for Ms. Hallett’s murder by distributing weapons around the apartment but in the end, none of them would be necessary. Soon after the phone call, Ms. Hallett arrived: “I came up behind her and crooked my arm around her neck, like this,” Kemper said, bending his powerful arm in front of himself at chin level. “I squeezed and just lifted her off the floor. She just hung there and, for a moment, I didn’t realize she was dead … I had broken her neck and her head was just wobbling around with the bones of her neck disconnected in the skin sack of her neck.”
Later that night, Kemper attempted to have intercourse with Ms. Hallett’s body.
He fled the next day in her car.
Kemper said he had to kill a friend of his mother’s “as an excuse.” In other words, Kemper said he had to provide a reasonable story for friends of his mother’s to explain her absence. If she were away on a trip with a friend, Kemper reasoned, nobody would be concerned about her absence.
At his 2017 parole hearing, Kemper gave an alternate explanation as to why he murdered Sally Hallett. He said it was revenge for ruining his mother’s holiday. The two women were supposed to go to Europe together for four weeks, but Hallett backed out at the last minute. Clarnell went on the trip by herself. At some point, during the hearing, Kemper referred to Hallett as his mother’s “lover”, but: “When [my mother] got back, she tried sharing those vacation moments with Sally, and Sally got very loud with her and rude, and told her ‘I don’t want to hear about that. I didn’t even go on that vacation, why are you bringing this up?’ So, she – that cut off that release. So, here I am at the house having heard this from my mother and she’s frustrated and I said ‘I’d like to know, I’d like you to share with me.’ So, she went and got all of her travel logs and the papers and stuff from the places that she went and she started systematically sharing this stuff with me, and then all of a sudden, she stops and she looks at me in this strange way, and she said, ‘I’m not gonna let you pity me.’ And she just walked away from the whole thing. And I said, ‘Hey, I wanted to hear this stuff…’
“I had told myself that if my mother ever dies over this stuff that I did, [Hallett]’s going with her. That’s one trip she’s not gonna miss. She’s not gonna back off on that one… I swore an oath to it. I was angry at the time… I haven’t sworn many oaths in my life and everyone that I have sworn I followed through with.”

There were moments, prior to her death, when Kemper felt like punishing his mother. Kemper told investigators he had killed his mother to spare her the suffering and shame that knowledge of his crimes would bring. He said: “There were times when she was bitching and yelling at me that I felt like retaliating and walking over to the telephone in her presence and calling the police, to say, ‘Hello, I’m the coed killer,’ just to lay it on her.”
Kemper’s testimony in court revealed his desire to punish his mother did not end with the fatal hammer blow. He cut off his mother’s head, “put it on a shelf and screamed at it for an hour … threw darts at it,” and ultimately, “smashed her face in,” he recalled for the horrified court. [Kemper supposedly performed irrumatio with his mother’s head, but that story is not verified.]
He went even further and cut her tongue out, as well as her larynx, and placed them in the garbage disposal. However, the garbage disposal could not break down the tough vocal cords and ejected the tissue back into the sink. Kemper found it rather ironic: “That seemed appropriate. As much as she’d bitched and screamed and yelled at me over so many years.”

The following is from a taped interview between suspect Edmund Emil Kemper III and Investigator Michael Aluffi, held at the Santa Cruz Jail on April 28, 1973.
Aluffi: This interview will be based around the incidents that occurred at your home last Saturday [April 21, 1973]. Is there anything that you want to tell me that led up to this incident?
Kemper: Not really.
Aluffi: Well, let’s start with the reason for it.
Kemper: That’s rather involved. The reason for it is these murders were coming to a head I felt, that I was going to be caught pretty soon for the killing of these girls, or I was going to blow up and do something very open and get myself caught, and so I did not want my mother… A long time ago I had thought about what I was going to do in the event of being caught for the crimes and the only choices I seen open is being that I could just accept it and go to jail and let my mother carry the load, and let the whole thing fall in her hands like happened last time with my grand-parents. Or, I could take her life. Well, I guess that leaves me two choices, I could either do it in the open with her knowing what was happening or I could do it when she didn’t know what was happening. Last Friday night, whatever date that was, I had decided it was the night before the killing, or the day before the killing really, I had been thinking about it for quite a while and I just started working myself up towards the act of killing her. I guess that answers the reason.
Aluffi: All right, you want to get into the actual crime?
Kemper: OK. I got home Friday night, or I got back to her home from Alameda, where I’d been working early Friday in the afternoon and I sat around the house and took care of a few business problems, you know, calling and making a couple phone calls that were unrelated to the problem, and I called my mother at work and let her know I was in town and she told me that she was going out to a dinner, some faculty dinner or something, and she’d be home late. So, I sat around and drank some beer, watched television, stayed up as late as I could and I had wished to talk to her really, before anything had happened. It was my hopes that she would go on good terms and this was impossible because, well I guess it would be good terms because we hadn’t really argued or anything when we talked on the phone. I went to bed about midnight I guess and I woke up a couple hours later. Well, let me see, that doesn’t work out right. I think I went to bed around two and she still wasn’t home and I went to bed and went to sleep. I woke up a couple hours later, around four, and she had already come home, done whatever she does when she gets home late at night and had retired for the evening. This was after I had gone to bed around 2:00 AM Saturday morning. She was in bed, reading a book and I woke up about four o’clock in the morning, two hours after I went to sleep roughly. The lights were pretty much out in the house. I didn’t see any lights on. I hadn’t heard anything and I thought, gee, it’s four o’clock and she’s still not home. So, I got up and I walked out of my bedroom, noticed her small light was on and walked into her bedroom, just as she had taken off her glasses and turned the light off. Without her turning it back on, she commented that uh, I said oh, you’re home, and she says, you’re up, what are you doing up? I said well, I just wanted to see if you were home. I hadn’t heard anything. She said, oh I suppose you want to talk. This has happened several times before, when she’d come in late and I wanted to talk and we’d talk and then she’d go to sleep. She didn’t say it in an abusive manner, it was more or less just jive and I said no. She said well, we’ll talk in the morning. I said fine, good night. She left the light out and I walked out of the room and back to my bedroom, layed down and decided at that point, I was going to wait another hour or so, until she was asleep before it happened.
Kemper: I looked at my watch. It was about a quarter after four, something like that, and I layed there in bed thinking about it and it’s something hard to just up and do. It was the most insane of reasons for going and killing your mother. But I was pretty fixed on that issue because there were a lot of things involved. Someone just standing off on the side, watching something like that isn’t really going to see any kind of sense or rhyme or reason to anything. I had done some things and I felt that I had to carry the full weight of everything that happened. I certainly wanted for my mother a nice quiet, easy death like I guess everyone wants. The only way I saw this possible was for it to be in bed, while she was asleep. The next thing was to decide how to do it. The only possible answer to that I saw was to take a hammer and hit her with it, in her sleep, and then to cut her throat. So, I waited till about 5:15 AM, I went into the kitchen and got a hammer. We have a regular claw hammer at home, picked up my pocket knife, the same one I’d used to kill Mary Anne Pesce with, opened it up, and I carried that in my right hand and the hammer in my left, walked into the bedroom very quietly.
Kemper: She had been sound asleep. She moved around a little bit and I thought maybe she was waking up. I just waited and waited and she was just laying there. So, I approached her right side, to my right on the right side of the bed, on her side. I stood there for a couple of minutes and spent most of that day, and most of that week I suppose and most of that night, trying to get myself I guess you’d say hopped up to do something like that, thinking nothing but reasons to do it and the need to do it, trying to keep everything else out of my mind. I stood by her side for a couple of minutes I suppose and about 5:15 I struck and I hit her just above the temple on her right side of the head, the side that was up from the pillow. It was above and behind her temple on the right side of her head. I struck with a very hard blow and I believe I dropped the hammer, or I layed it down or something. Immediately after striking that blow, I looked for a reaction, and there really wasn’t one, blood started running down her face from the wound, and she was still breathing, I could hear the breathing and I heard blood running into her, I guess it was her windpipe. It was obvious I had done severe damage to her, because in other cases where I had shot people in the head, I heard the same, or it had the same effect, blood running into the breathing passages, and this all happened in a few moments.
Kemper: But after I struck, I moved her over in the bed on her back and with my right hand holding her chin up, I slashed her throat. She bled profusely all over and I guess it was an afterthought, I hadn’t really thought of it, but her being my mother, and me out doing those other things, and I knew right off if I had torn everything out in the open, and my plan which I didn’t mention earlier, had been to just, well everything’s getting to an end and I could either kill her and turn myself in or I could kill her and head out with everything I had, my arsenal. This was my choice at that time. So, I decided at that time, it’s a hell of a cliché to use, but I guess what was good for my victims was good for my mother. So, after I slashed her throat, I went ahead and slashed the rest of the way around her neck and took off her head, and I guess half as much of that was to make absolutely sure in my own mind that she was dead instantly and right then, so the whole attack took maybe, less than half a minute, possibly even as little as 20 seconds…

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

Testifying as the first defense witness in Ed Kemper’s trial, Allyn Kemper, 22, revealed under cross examination that both she and her mother thought Kemper might have been involved in the death of Cynthia Schall.
Allyn Kemper testified that she asked her brother directly whether he had anything to do with the killing – one of eight of which he is accused.
“No,” she quoted him in response, “but I was afraid you might be suspicious because of that cat thing. My mother has already asked me about it, and I’d appreciate it if you didn’t bring it up again because it will just stir things up.”
The “cat thing” Miss Kemper explained, involved an incident when the family lived in Montana and her brother decapitated the family cat with a bayonet.
Under questioning by District Attorney Peter Chang, she also related that she herself was almost killed by Kemper.
That, too, happened in Montana. Kemper, she explained, had always had an interest in guns, and one day as she walked through the living room she heard a click.
As she turned, she said, a bullet from Kemper’s .22 rifle whizzed by her ear and buried itself in a bookcase.
“Oops!” she quoted her brother. “I thought it was empty.”
