When David Kaczynski talks about his brother, he recounts a caring sibling, seven years his senior, who once attached an empty spool to a screen door at three-year-old Kaczynski’s eye level, so the youth could get back inside after playing in their backyard outside Chicago.
Most Americans remember his brother as the Unabomber, the FBI’s most-wanted man in the mid 1990s who was convicted of sending homemade bombs through the mail during a 17-year period. He killed three and injured 23 during his campaign, conducted from a secluded Montana cabin.
