In papers found in his Montana cabin, Theodore Kaczynski admitted committing “nonbombing acts of violence,” prosecutors said in documents filed Wednesday.
The government did not say what the acts of violence were. Justice Department spokeswoman Leesa Brown said she could not release any information.
A federal law enforcement source who spoke on condition of anonymity, however, said the acts were serious and have never been made public.
Defense attorney Quin Denvir said the prosecution was referring to “some acts of vandalism which we don’t feel have any place in this trial,” and that Kaczynski committed when he was much younger.
“Mr. Kaczynski is on trial for allegedly committing four acts involving the placing of bombs,” Denvir said. “These vandalism acts are irrelevant.”
The government contends Kaczynski is the anti-technology terrorist known as the Unabomber who is responsible for 16 bombings - including one in Salt Lake City - over 17 years that killed three and injured 23.
Kaczynski, 55, faces trial Nov. 12 on a 10-count indictment charging him with using bombs to kill two Sacramento men and injure two others. He faces the death penalty if convicted. He also has been charged in New Jersey with the bombing death of an advertising executive. He has pleaded innocent to all charges.
