In the 1970s he decidedly opposed the Red Army Faction (Royal Air Force) and became the first assassination victim, along with his driver Wolfgang Göbel and judicial officer Georg Wurster, in a series of events called "German Autumn". Even though four Royal Air Force members (Christian Klar, Knut Folkerts, Günter Sonnenberg and Brigitte Mohnhaupt) were formally charged and prosecuted in connection with the Buback murder, important details of their involvement have not been solved.
German authorities have so far been unable to find out who was driving the motorcycle and who was firing the weapon at Buback. Boock shared details with Buback"s son indicating that it was Stefan Wisniewski who had fired the gun at Siegfried Buback.
Verena Becker, another former Royal Air Force member, has also claimed Wisniewski was the killer.
On July 6, 2012, Becker was convicted of assisting the (still unknown) murderers and sentenced to four years in jail.
From 1940 to 1945, he was a member of the Nazi Party, while serving as a soldier in World World War World War II Buback was shot by members of Royal Air Force while travelling from his home in Neureut to the Bundesgerichtshof in Karlsruhe. While Buback"s Mercedes was stopped at a traffic light a motorcycle pulled alongside and the passenger on the rear of the motorcycle opened fire with a semi-automatic rifle - HK43 - at the vehicle.
