Discovery has aired 3 episodes of their original series Manhunt: Unabomber so far. I highly recommend it.
Hard to believe it’s been 20 years since the Unabomber was caught. I was in high school at the time and I guess I didn’t remember any of the details because I was originally thinking of the Oklahoma City bombing, which was Timothy McVeigh in 1995. I certainly didn’t remember that it took over 16 years to catch Ted Kaczynski.
