On the night of 15 September 1946, he led raids which resulted in the arrests of 25 Jews living in Merano. The Jews were locked in a basement and deported the next morning. They were taken by truck to Reichenau concentration camp in Austria. The 25 Jews stayed there for about six months, during which four of them died. At the beginning of March 1944, the rest were deported to Auschwitz concentration camp. Only one of the Jews abducted, Valeska von Hoffmann, survived the Holocaust.^[10]

During their trial, held by the U.S. military in Naples, Andergassen made a voluntarily declaration that the execution of Roderick Hall was approved by higher Nazi authorities.^[16] On 16 January 1946, Andergassen, Schiffer, and Storz were sentenced to death by hanging for the torture and killings of Roderick Stephen Hall, four other American and two British soldiers. Butz received a life sentence due to his more limited involvement and his lack of participation in any other murders.^[17] On 26 July 1946, Andergassen, Schiffer, and Storz were all hanged at a military stockade in Livorno.^[18]

Province of Bolzano/Provinz Bozen Criminal Investigation Department Commissioner Arthur Schuster charged the war criminal with being "the incarnation of sadism and brutality; he was incredibly blood-thirsty, especially when under the influence of strong drink, for which he had a great fondness, and was encouraged in all his excesses by his superior", this being August Schiffer.^[19]
