In early 1996, Kaczynski demanded that his lengthy neo-luddite manifesto outlining the evils of technological society be printed by a major newspaper; he would then end his bombing campaign. The pamphlet was published by the New York Times and Washington Post, with the hope that somebody would recognize his writing style. This did indeed happen: Kaczynski's younger brother David notified authorities, who arrested him in his remote cabin outside Lincoln, Montana. David had gotten assurances from the FBI that he would remain anonymous and that in particular his brother would not learn who had turned him in. Kaczynski avoided the death penalty by pleading guilty (his lawyers were attempting an insanity defense which he rejected) and is serving a life sentence without the possibility of parole in a maximum security prison in Colorado.
