Unabomber Part 1: The Biggest Manhunt in FBI History

Before Ted Kaczynski was a name on the news, the Unabomber was an anonymous figure who could vanish for years and return with a more lethal device. Part One follows the hunt from the first 1978 package bomb to the manifesto that finally made his anonymity vulnerable.

In 1978, a brown-paper parcel was found between two cars at a Chicago university. It looked ordinary. The professor named as the sender had never seen it before. Then it exploded.

That first device began a 17-year bombing campaign that moved from university campuses to an airliner, computer shops and private homes. Sixteen bombs would kill three people and injure 23, while investigators struggled with devices deliberately built from common materials and a bomber capable of disappearing for years.

What the FBI did have was strange: scrap-built components, pieces of wood, the initials F.C., a witness sketch and, eventually, a bomber who decided to start writing. Part One follows the creation of the UNABOM investigation, the long silences between attacks, the deadly return in the 1990s and the extraordinary decision to publish Industrial Society and Its Future.

Then, after thousands of bad tips, one lead arrived that pointed towards a name already inside the investigation: Ted Kaczynski.
