What happened to Ted Kaczynski
Ted Kaczynski, also known as the Unabomber, died in prison on June 10, 2023. His death was reported as an apparent suicide by hanging in the administrative maximum security facility at ADX Florence, Colorado. He had been transferred there in 2021 after earlier moves between facilities, including periods at USP Florence ADMAX and a medical center for treatment of chronic conditions. The trajectory from his 1996 arrest, through decades of litigation and solitary confinement, concluded at ADX Florence with a death that triggered standard federal autopsies and reviews.
Arrest, trial, and sentencing context
Kaczynski was arrested in 1996 and entered a guilty plea in 1998 that waived his right to trial and eliminated the possibility of a death sentence, securing life in prison without the possibility of parole. This avoided a protracted federal death penalty trial over his 17-year bombing campaign. Although removed from the death row unit at USP Florence ADMAX in 2021, his sentence remained unchanged, and he was held in protective custody at ADX Florence until his death.
Custody moves leading to his death
Between 1998 and 2021, Kaczynski was moved across several high-security federal facilities for trials, medical care, and administrative reasons. After waiving execution appeals in 2021, he was transferred to ADX Florence, the federal supermax, where Bureau of Prisons staff monitored him under specialized housing protocols. Official reports indicate he was found unresponsive in his cell and pronounced dead at the scene, marking the final institutional episode in a lifelong confinement.
