During a 17-year bombing campaign, an elusive terrorist known as the Unabomber killed three people and injured a further 23.

Theodore Kaczynski was a serial killer obsessed with technology. In 1995, he contacted The New York Times and The Washington Post promising to stop his terror attacks if they published his 35,000-word manifesto. The document explained his aim: to dismantle modern industrial society.

On the advice of the FBI and the US Attorney General, the newspapers published the manifesto, which led to the Unabomber鈥檚 downfall. Dr Kathleen Puckett, the FBI agent who helped uncover his identity, tells her story.
