Above is a police sketch of Theodore Kaczynski. The Unabomber was an "FBI code name given to supposedly solo anti-technology serial killer whose bombs killed three and injured twenty-three others over a 22-year period. Dubbed "Unabomber" because his first targets were related to universities (as well as airlines), the bomber managed to elude a combined investigation by the U.S. Postal Service, the FBI, and the Bureau of Alcohol, Tobacco, and Firearms, as his devices--usually sent through the mail--struck nationwide targets whose only apparent connection was to technology."
