The exhibit centers around how Kaczynski lived, how he did his deadly bomb-making work and how authorities caught him. The items featured include a hand bowed wood saw, one of which Kazcyznski used to build his Montana log cabin by hand, a Hanson model 1509 scale where Kaczynski carefully calibrated the explosives for his bomb recipes, FBI evidence bags and Kaczynski’s passport photo.
The museum paid around $2,000 for all the items as part of a May U.S. Marshals auction, said Chief Operating Officer Janine Vaccarello. The auction came out of a court order to sell Kaczynski’s items and give the proceeds to his victims.
Kaczynski got his nickname from law enforcement officials because he sent homemade bombs through the mail to universities and airlines. Between 1978 and 1996 when he was caught, his bombs killed three people and injured more than a dozen.
The Northwest Washington museum does not have the famed Unabomber manifesto, the 35,000-word manuscript in which Kacyznski assailed modern society. But the exhibit features a panel desribing how law enforcement specialists profiled Kacynzski’s style of writing — known as forensic linguistics — and when Kacynzki’s brother David stepped forward and said the writing sounded like his brother, authorities were able to crack the case by comparing samples furnished by the brother to the manifesto.
