Transition to Criminal Activity

Disillusioned with technology and modern society, Kaczynski retreated to a remote cabin in Montana in 1971, where he began constructing and mailing bombs. His campaign targeted those involved with modern technological development over the next 17 years.

Publication of the Manifesto

In 1995, the Unabomber sent a 35,000-word manifesto to media outlets, demanding publication in exchange for stopping the bombings. The manifesto played a critical role in identifying linguistic patterns that assisted the FBI.
