FBI agents arrested Kaczynski on April 3, 1996, at his cabin, where he was found in an unkempt state. A search of his cabin revealed a cache of bomb components, 40,000 hand-written journal pages that included bomb-making experiments, descriptions of the Unabomber crimes and one live bomb, ready for mailing. They also found what appeared to be the original typed manuscript of ''Industrial Society and Its Future''. By this point, the Unabomber had been the target of the most expensive investigation in FBI history.
After his arrest, Kaczynski tried unsuccessfully to dismiss his court-appointed lawyers because they wanted him to plead insanity in order to avoid the death penalty, as he did not believe that he was insane. In 1998, a plea bargain was reached under which he pleaded guilty to all charges and was sentenced to eight life sentences without the possibility of parole. He has been imprisoned at ADX Florence, a supermax prison in Florence, Colorado. In December 2021, the 79 year old Kaczynski was transferred to the Federal Medical Center in Butner, North Carolina.
