He was tagged as the "Hammer-Killer" for his modus operandi of killing drivers of cars and using a sledgehammer in later bank robberies in which he would use his victims" cars as getaway vehicles. On May 3, 1984, 47-year-old Siegfried Pfitzer was found dead, shot in the head, at a highway rest stop in Marbach, West Germany. His car, found a quarter-mile from his body, was linked to a bank robbery the same day in Erbstetten.
The assailant had smashed the teller window with a sledgehammer, and taken the money on the other side.
On December 21, 37-year-old Eugene Wethey was found shot dead in a rest stop near Grossbottwar. A week later, Wethey"s car was used in a bank robbery in Cleebronn by a man wielding a sledgehammer.
On July 22, 1985, 26-year-old Wilfried Scheider was found shot dead in a parking lot in Beilstein-Schmidhausen. He was shot with a Walther P5 pistol, a common police issue pistol.
The victim"s car was found at the scene of a bank robbery in Spiegelberg.
On September 29, 1985 while searching a Ludwigsburg railway station for bombs, anti-terrorist officers found a police uniform in one of the lockers. The uniform was traced to detective chief superintendent Norbert Poehlke, a veteran officer of 14 years in Stuttgart. Poehlke said it had been left there after a quick change for a family member"s funeral.
The investigation was picking up when, on October 14, Poehlke requested, and got, some sick leave.
Several days later police went to his home to ask him some questions regarding the murders and robberies. With no one answering, and fearing Poelhke had fled, the police entered the house.
Poehlke"s pistol was confirmed as the murder weapon in the murders, and the case was closed.
