Unabomber in a federal medical prison by hanging himself inside his cell, according to a 911 call from the detention center.
An official called in the suicide early Saturday morning at FMC Butner, in North Carolina, noting medics were working on “a guy that was hanging,” TMZ reports.
The caller provided few details in the brief recording, only noting that there was a “crash cart” at hand in response to the hanging. A crash cart refers to a wheeled drawer that carries medical equipment for use in emergencies.
Kaczynski’s body allegedly suffered neck injuries, including a deformed trachea as a result of the hanging, sources told the outlet.
Officials said the infamous convict — who carried out a 17-year bombing spree that killed three and injured 23 others — was found unresponsive inside his cell around 12:30 a.m, but have yet to name the exact cause of death other than suicide.
Kaczynski, 81, had been moved to the medical prison in December 2021 due to his poor health after being diagnosed with late-stage cancer.
Kaczynski had in 1998 before trial — by hanging himself with his own underwear, according to reports at the time.
He had served only 25 years of his more than four-life terms sentence after he was turned in by his brother, David, who realized that his sibling was the elusive “Unabomber” after Kaczynski’s manifesto was published.
Kaczynski was an Ivy League-educated math professor who left society to live in a cabin in Montana.
He is believed to have set off his first homemade explosive at a Chicago university in 1978, and he ultimately confessed to carrying out 16 bombings between 1978 and 1995.
After receiving the tip from his brother, police captured Kaczynski at his small plywood and tarpaper cabin in the woods outside Lincoln, Montana.
The tiny home, smaller than the jail cell where he lived his final years, contained explosives, two finished bombs and a coded diary.
Despite his nearly two-decade reign of terror in the US, technophobes have embraced his anti-technology manifesto, with some dubbing him “Uncle Ted,” a phrase which trended on Twitter following his death.
Tech boss Elon Musk was among those tweeting about Kaczynski, claiming the killer “might not be wrong” about his belief technology is detrimental to society.
