In 1975, Bundy went to jail for the first time when he was incarcerated in Utah for aggravated kidnapping and attempted criminal assault. He then became a suspect in a progressively longer list of unsolved homicides in multiple states. Facing murder charges in Colorado, he engineered two dramatic escapes and committed further assaults, including three murders, before his ultimate recapture in Florida in 1978. For the Florida homicides, he received three death sentences in two separate trials.
Bundy was executed in the electric chair at Florida State Prison on January 24, 1989. Biographer Ann Rule described 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". He once called himself "the most cold-hearted son of a bitch you'll ever meet"; Attorney Polly Nelson-a member of his last defense team-wrote: "Ted was the very definition of heartless evil."
