The "Unabomber" terrorized the US.
Ted Kaczynski, nicknamed the "Unabomber," terrorized the United States for nearly two decades with a series of mail-order bombs.
The "Unabomber" first came to the attention of authorities in 1978 after a homemade bomb exploded at a Chicago university.
The Harvard graduate killed three people and injured 23 others before he was arrested in 1996.
Although the "Unabomber" eluded authorities for years, he was able to be caught after his brother identified his prose in his published manifesto.
Kaczynski pleaded guilty in 1998 and is serving a sentence of eight life sentences for murder.
Although the "Unabomber" was not charged with terrorism, the series of attacks it caused is considered a case of terrorism.
