Excerpt:
Kaczynski went on trial in Sacramento, California, where the key issue was not his guilt but his sanity and whether he would be spared the death penalty. He pleaded guilty to murder in exchange for life in prison without parole in 1998.
Kaczynski, who had attended Harvard at 16-years-old and earned a Ph.D. in math at the University of Michigan, had also threatened to blow up airliners, according to the FBI.
The prosecution of Kaczynski was supervised by the now Attorney General Merrick Garland when he was a senior Justice Department official. Garland also supervised the Oklahoma City Bombing investigation before he was Attorney General.
He grew up in Chicago, where his first bomb exploded, taught at the University of California, Berkeley, where two devices were left, and had lived in Salt Lake City, which was also a target, authorities said.
