On 27 June 1993, Hogefeld and Grams arrived at a train station in Bad Kleinen where a group of GSG 9 officers were waiting to arrest them (the officers had received a tip-off from a fellow GSG 9 officer who had infiltrated the RAF). According to the GSG 9 men, Hogefeld and Grams started firing at them on sight; Grams fatally shot an officer named Michael Newrzella. According to the police Grams committed suicide and fell on the train tracks. However, it was suspected that Grams did not commit suicide but was shot by GSG 9 officers. The Staatsanwaltschaft Schwerin investigated these allegations and concluded in January 1994 that they were incorrect. Grams' parents challenged this conclusion in court, but it was upheld by five different courts, including the European Court of Human Rights in 1999. Interior Minister Rudolf Seiters took responsibility for the poor conducting and postprocessing of the operation and resigned in July of the year, as well as Chief Federal Prosecutor, Alexander von Stahl.
