Bruno Lüdke

Police brought in Lüdke for questioning on 18 March 1943, where he quickly confessed to murdering not only the woman but also several other victims, and was taken into custody.

[citation needed] Witnesses report Lüdke showed signs of physical abuse and he stated that "they would kill me if I didn't confess".

[citation needed] Attempts at reopening the case by members of the Kriminalrat (Detective Major) Faulhaber yielded no results.

Today most historians believe Lüdke to be the victim of a frame-up, carried out by an ambitious Kriminalkommissar (Detective Captain) Franz, the heavily censored Reichskriminalpolizeiamt, and the Nazi government, that saw people with intellectual disabilities as inferior and welcome scapegoats.

[2][3] A 1957 movie directed by Robert Siodmak, Nachts, wenn der Teufel kam (English-language title The Devil Strikes at Night), doubted Lüdke as one of Germany's worst serial killers.
