The number one goal of the 27-year-old man, Stephan Balliet, who attacked a synagogue in Karlsruhe, southern Germany, was simple: “1. Prove the viability of improvised weapons.” While he killed two people outside the synagogue, his plans were thwarted when he couldn’t get inside. His guns also jammed, apparently he failed to test out his guns before his attack.
“People have been improvising weapons forever,” said Mark A. Tallman, who teaches at Colorado State University at Pueblo’s Center for the Study of Homeland Security and has written a history of ghost guns. “Making guns is relatively low technology.”
Among the guns that the killer made was a machine gun that appears to be based on blueprint designed by Philip Luty.
While German authorities have not yet confirmed the types of weapons used in the attack, some arms experts online said it was clear from images of the weapons used in the attack that at least one of the guns was built from a distinctive Luty submachine blueprint.
The killer apparently made six different guns, such as a shotgun, as well as homemade hand grenades.
The attack occurred on October 10, 2019.
