In 1974, Knowles went on a deadly, four-month, cross-country rampage after his fiancee dumped him on the advice of a psychic, killing between 18 and 35 people, including hitchikers, elderly women and a young mother while her 2-year-old watched.
He took a Florida trooper hostage and used the officer's patrol car to pull over another vehicle, then shot both hostages.
Knowles was finally captured by an armed civilian after crashing his car at a roadblock in Georgia. While in a police car, Knowles used a paper clip to unlock his handcuffs.
He grabbed an officer's handgun and was shot dead.
