Kaczynski, 81, who killed three people and wounded 23 others, was found dead in his cell. He terrorized America between 1978 and his capture in 1995, only after the media agreed, on the recommendation of the FBI, to publish his radical manifesto against modern society.
Samuel Little, the American prisoner who claimed to have killed more than 90 women across the country, is now considered the deadliest serial killer in US history. He was sentenced to life imprisonment without parole and held in high-security detention facilities.
