'Unabomber' Ted Kaczynski Passes Away at 81.

Ted Kaczynski, also known as the Unabomber, died at the age of 81 in his prison cell. He was responsible for a violent one-man campaign from 1978 to 1995, using homemade bombs to attack academics, businessmen, and civilians with the goal of bringing about the collapse of modern society. His actions resulted in the deaths of three people and injuries to 23 others. Kaczynski was a Harvard-trained mathematician who became a rural recluse and was eventually caught after the longest and most costly manhunt in American history.
