Serial killers from California

Theodore Robert Bundy (né Cowell; November 24, 1946 – January 24, 1989) was an American serial killer who kidnapped, raped and murdered dozens of young women and girls during the 1970s and possibly earlier. After more than a decade of denials, he confessed to 30 murders committed in seven states between 1974 and 1978. His true victim total is unknown.Bundy often employed charm to disguise his murderous intent when kidnapping victims, and with law enforcement, the media and the criminal justice system to maintain his claims of innocence. His usual technique involved approaching a female in public and luring her to a vehicle parked in a more secluded area, at which point he would beat her unconscious, restrain her with handcuffs and take her elsewhere to be sexually assaulted and killed.
Bundy typically simulated having a physical impairment such as an injury to convince his target that he was in need of assistance, or would dupe her into believing he was an authority figure. He frequently revisited the bodies of those he abducted, grooming and performing sex acts on the corpses until decomposition and destruction by wild animals made further interactions impossible. He decapitated at least 12 of his victims, keeping their severed heads as mementos in his apartment. On a few occasions, he broke into homes at night and bludgeoned, maimed, strangled and/or sexually assaulted his victims in their sleep.
In 1975, Bundy was arrested and jailed in Utah for aggravated kidnapping and attempted criminal assault. He then became a suspect in a progressively longer list of unsolved homicides in several states. Facing murder charges in Colorado, Bundy engineered two dramatic escapes and committed further assaults in Florida, including three murders, before being recaptured in 1978. For the Florida homicides, he received three death sentences in two trials, and was executed in the electric chair at Florida State Prison in Raiford on January 24, 1989.
Biographer Ann Rule characterized him as "a sadistic sociopath who took pleasure from another human's pain and the control he had over his victims, to the point of death and even after." Bundy once described himself as "the most cold-hearted son of a bitch you'll ever meet", a statement with which attorney Polly Nelson, a member of his last defense team, agreed. "Ted", she wrote, "was the very definition of heartless evil."

Theresa Jimmie Francine Knorr (née Cross; born March 14, 1946) is an American woman convicted of torturing and murdering two of her six children while using the others to facilitate and cover up her crimes. She was acquitted of murdering her first husband and was also considered a suspect in the unsolved murder of her sister.

Carroll Edward "Eddie" Cole (May 9, 1938 – December 6, 1985) was an American serial killer who was executed in Nevada in 1985 for killing two women by strangulation. He was also convicted of murdering three other women in Texas and is believed to have murdered up to thirty other people between 1947 and 1980.

Angel Maturino Reséndiz (August 1, 1959 – June 27, 2006), also known as The Railroad Killer, was a Mexican serial killer suspected in as many as 23 murders across the United States and Mexico during the 1990s. Some also involved sexual assault. He had become known as "The Railroad Killer", as most of his crimes were committed near railroads, where he had jumped off the trains which he was using to travel around the country.
On June 21, 1999, he briefly became the 457th fugitive listed by the FBI on its Ten Most Wanted Fugitives list, before he surrendered to the Texas authorities on July 13, 1999. He was convicted of capital murder in Texas, and executed by lethal injection in 2006.

Herbert William Mullin (April 18, 1947 – August 18, 2022) was an American serial killer who killed 13 people in California in the early 1970s. He confessed to the killings, which he claimed prevented earthquakes. In 1973, after a trial to determine whether he was legally insane or culpable, he was convicted of two murders in the first-degree and nine in the second-degree, and sentenced to life imprisonment. During his imprisonment, he was denied parole eight times.Mullin and Edmund Kemper overlapped in their 1972 to 1973 murder sprees, adding confusion to the police investigations and ending with both being arrested, within a few weeks of each other, after the deaths of 21 people.

David Joseph Carpenter (born May 6, 1930), also known as The Trailside Killer, is an American serial killer and serial rapist known for stalking and murdering a variety of individuals on hiking trails in state parks near San Francisco, California.
