“Unabomber” Theodore Kaczynski wrote a letter to a three-judge panel of the U.S. Court of Appeals complaining that the cabin where he had plotted his crimes was part of a display at the Newseum in Washington.

The convict, who is serving a life sentence with no possibility of parole, explained in the letter that the exhibit went against the wishes of his victims to reduce extensive publicity upon the case.

As reported by The Associated Press, the 10-foot by 12-foot cabin is the largest of about 200 objects included in the “G-Men and Journalists: Top News Stories of the FBI’s First Century” exhibit, which was opened two months ago. Among other displays, John Dillinger’s death mask, the electric chair in which baby kidnapper Bruno Hauptmann was executed and Patricia Hearst’s coat are also put on view.

Theodore Kaczynski wrote in the three-page, handwritten letter addressed to the San Francisco Court that he find out his cabin was at the Newseum from a newspaper ad in the Washington Post, according to the AP.

The windswept cabin was deposited in an FBI evidence facility following the “Unabomber’s” bombing spree, which ran from 1978 to 1995, killing three people and wounding 23 others.

The Harvard-trained mathematician was caught at the Lincoln, Mont., cabin more than a decade ago. Moreover, he pleaded guilty in 1998, two years after being captured, and is held in a maximum security prison in Colorado.

He was dubbed the “Unabomber” because he targeted some of his attacks at university scholars.
