Apparent Original Copy Of Manifesto Found In Cabin -- Typewriter, Letter From Unabomber To Paper Also Found

WASHINGTON - What appears to be the typed original of the Unabomber's 35,000-word manifesto has been found in the cabin of suspect Theodore Kaczynski, a law-enforcement source said yesterday.

The FBI crime laboratory has also tentatively linked a typewriter found in the cabin to evidence from several bomb scenes, federal sources confirmed yesterday.

Investigators found the manuscript several days ago, but word of the discovery did not leak out until yesterday. The manuscript and the typewriter comparison appear to be the "something big" that government sources had said earlier this week they had found and which had given them great confidence that Kaczynski could be charged as the serial bomber who carried on a campaign of terror for 17 years.

The manuscript was found during the search of the former math professor's Montana cabin.

U.S. News and World Report said agents told the magazine that the manuscript was indeed the original copy and was prepared on one of three typewriters removed from the cabin.

Also found with the manifesto was the original of a letter the Unabomber sent to The New York Times last year, the Times reported in editions today.

The Unabomber has sent several letters to the Times; it wasn't immediately clear which one this was, the Times said, but it was believed to be one relating to a demand that the manifesto be published.

The manuscript and typewriter were found in a "cramped loft" of

Kaczynski's tiny home, the magazine said yesterday. U.S. News and World Report was to carry an article on the discovery in its April 22 issue, on newsstands Monday.

The manifesto, entitled "Industrial Society and Its Future," was published last September by The Washington Post in cooperation with the New York Times after consultation with the Justice Department.

The Unabomber had demanded publication as his price for ceasing his string of fatal bombing attacks.

The manifesto, which attacks the dehumanizing nature of modern society, was apparently a key in identifying Kaczynski. His brother, David Kaczynski, contacted the FBI after reading the manifesto and matching it to letters sent by Theodore Kaczynski.

Before Kaczynski emerged as a suspect, investigators had said that the Unabomber, in keeping with his anti-technology philosophy, had typed out the manifesto on a manual typewriter using carbon paper to make his copies. His typographical errors, authorities noted, were not corrected in the carbon copies.

Besides the manifesto, the Unabomber wrote a number of letters, all of them signed "FC," to newspapers as well as to professors, scientists and at least one victim.

Kaczynski, a 53-year-old former University of California, Berkeley, professor, was arrested last week at the remote cabin near Lincoln and is being held on a single count of possessing bomb components.

He has not been charged with any of the 16 Unabomber attacks that killed three people and injured 23 in nine states over the past 17 years.
