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…”

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.”
