A former Nazi SS sergeant, now 94, who allegedly served at Auschwitz was charged with 3,681 counts of accessory to murder.

German prosecutors charged the man, who has not been named due to German privacy laws, on Monday.

The suspect allegedly served as a medic in an SS hospital at Auschwitz in August-September 1944. He is one of several former suspected guards at the concentration camp who have been investigated and charged in recent months under a precedent in German law set in the John Demjanjuk case, in which being a guard at a death camp was sufficient to prove complicity in murder.

Demjanjuk was convicted in 2011 for his role in the murders of nearly 30,000 Jews at Sobibor.

Last week, a past member of the SS was likewise charged as an accessory in the killings of some 170,000 people, the majority Jews, at the notorious Auschwitz Nazi camp. The man, now 93, is one of several former guards who have been investigated and charged in recent months. His name has not been revealed.

The man reportedly admitted to being stationed at the camp from early 1942, but he denies having any involvement in murder, according to the state prosecutor of Dortmund.

Investigators say the accused was involved in murders from January 1943 to June 1944 involving Jews deported from Hungary, mass shooting operations and the “selection” of ill and weak deportees on the arrival ramp for extermination, the German broadcasting agency WDR reported. He also allegedly knew that the systematic murder could not have taken place without assistants like him, according to the charge.
