These included the West Berlin police, the Central Registry of State Judicial Administration in Salzgitter (which tracked all border fatalities) and the Arbeitsgruppe 13 August (Working Group 13 August), a West Berlin association. Within the jurisdiction of the West-Berlin police, the State Security Department was responsible for the registration of known incidents. The records distinguish between individuals who died at the outer border of West-Berlin (80 incidents), unclear incidents (with 5 possible wall victims) and border guards who were shot.
