Theodore “Ted” Kaczynski, the Harvard-educated mathematician who ran a nearly two-decade-long bombing spree that killed 3 and injured 23, died Saturday (June 10) at 81.

As reported by AP News, the man branded by the FBI as the “Unabomber” died at the federal prison medical center in Butner.

Federal Bureau of Prisons spokesperson Kristie Breshears confirmed Kaczynski’s death at around 8 am Saturday morning, after being found unresponsive in his prison cell.

Prior to his transfer to Butner, Kaczynski was held in the federal Supermax prison in Florence, CO since he was sentenced to four life sentences plus 30 years for his crime spree in May 1998. He admitted to committing 16 bombings from 1978 to 1995.

In the midst of his spree, his 35,000-word manifesto, “Industrial Society and Its Future,” was published by The Washington Post in September 1995. In it, Kaczynski claimed that modern society and technology were leading to a sense of powerlessness and alienation.

However, the manifesto ultimately led to his capture, as Kaczynski’s brother and sister-in-law recognized his tone and tipped off the FBI. He was captured in April 1996.
