A suspect in the Unabomber case is in custody, although federal officials say the man was neither arrested nor charged.
Theodore John Kaczynski was taken into custody so that he would not interfere with the search of his home -- a mountain cabin in Montana.
This F-B-I demonstration shows exactly what a one of the Unabomber's explosives can do.
The crazed intellectual's spree began at Northwestern University outside Chicago in May 1978. Most of the victims have been scientists, although airlines have also been targetted.
Three people have died and 23 more were injured in 15 subsequent Unabomber attacks.
A Theodore J. Kaczynski, born May 22, 1942 in Chicago, graduated from Harvard in 1962 and taught as an assistant professor of mathematics at Berkeley in the 1967-68 school year, according to Harvard and Berkeley records.
He resigned in June 1969.
Last September, The New York Times and The Washington Post published, in the Post, his 35,000-word treatise on the inhumanity of industrial society after he promised to stop planting bombs that kill people.
His manifesto held that industrial society should be abolished and replaced with "small, autonomous units" of no more than 100 people.
There have been no bombings or incidents since then.
