Unabomber Exchanged Letters With CBS4 Investigator
DENVER (CBS4)- The FBI has requested a DNA sample from "Unabomber" Ted Kaczynski as part of its investigation into the 1982 deaths of seven Chicago-area people who took cyanide-laced Tylenol from packages that had been tampered with.
Kaczynski, who pleaded guilty in 1998 to setting 16 explosions that killed three people and is serving a life sentence in federal prison, has declined to voluntarily provide a DNA sample.
CBS4 Investigator Rick Sallinger communicated by mail with Kaczynski for some time in the late 90s. Watch his report below.
