Ed Kemper is one of the most notorious serial killers in US history. Known as "The Co-Ed Killer," Kemper murdered six young women — along with his grandparents, mother and his mother's best friend — in Northern California in the early '70s.
Oxygen's "Kemper on Kemper: Inside the Mind of a Serial Killer" revisits the chilling crimes of Edmund Kemper and the traumatic childhood that led him to kill. After turning himself over to police, Kemper was found guilty of eight counts of first-degree murder in November of 1973. While Kemper spends the rest of his life behind bars, many have wondered, what happened to the rest of his family?
Living In Fear
In 2017, Kemper's half-brother David Weber (a name he used to protect his real identity) spoke out for the first time. He told the UK's Daily Mail that the family lived in fear that Kemper would one day be released from prison after he was up for parole.
"He has this control over the family, and there's still anger over what he did. So many people live in fear that he could be allowed freedom," Weber said.
Hiding The Truth
Although the details of Kemper's crimes are widely known, Weber fears that Kemper is hiding the full truth of his depravity. He believes that only Kemper knows how many victims he murdered and that the killer has kept up to "30 percent" of the truth to himself.
Kemper's crimes hit close to home. In addition to killing his mother, his first victims were his grandparents. Weber says that some members of the family are still angry and want revenge.
"There are several members of the extended family that have claimed they'd hunt [Ed] down and kill him if he ever got out. Mostly for killing my grandparents, but also for hurting so many people while destroying our whole family unit. This is while feeling zero remorse for what he did," said Weber.
Kemper asserts that his murderous streak was partly brought by a domineering mother. Kemper's mother, Clarnell Strandberg, and father, Edmund Emil Kemper II, split up when Kemper was just a boy, and he was raised by Clarnell and his two sisters.
Although it's been said that he abandoned the family when Kemper was 9, Weber denies this. Kemper II remarried and died in 1985.
Little is known about Kemper's sisters, Allyn Smith and Susan Swanson. According to Weber's interview, they have faith in their brother and believe he's a "good person who did bad things."
It appears that Swanson passed away in 2014 and is buried in Montana.
