Peter-Jürgen Boock moved out of his parents' house in his youth to live in a commune. He was sent to a reform school for drug possession, where he met the RAF founding members Andreas Baader, Gudrun Ensslin and Astrid Proll. He became active in the RAF scene in 1975 and took part in their actions from 1977 onwards. Among other things, he was involved in the kidnapping of Hanns Martin Schleyer and the "Landshut" plane hostage-taking. Although he distanced himself from the RAF in the following years, he had to serve a prison sentence from 1981 to 1998. Today, Boock works as an author.
