A former Nazi concentration camp guard who settled in Racine, Wisconsin, after World War II and acquired U.S citizenship, was deported on Thursday to Austria for his participation in Nazi-sponsored acts of persecution during World War II, according to reports released by the US Departments of Justice and Homeland Security.

Josias Kumpf, 83, served as a SS "Death's Head" guard at the Nazi-run Sachsenhausen Concentration Camp in Germany and at the Trawniki Labor Camp in Poland.

According to DOJ documents, Kumpf also served at slave labor sites in Nazi-occupied France where prisoners under his watch built launching platforms for German V-1 and V-2 missile attacks on England.
