A federal immigration judge on Tuesday ordered the deportation of an 85-year-old German citizen who authorities said served as a Nazi concentration camp guard. The order came after Paul Henss, who lives in Georgia, failed to show up for a deportation hearing. Authorities maintain that Henss trained and handled attack dogs at the Dachau and Buchenwald concentration camps and that he aided in the Nazi persecution of Jews - a crime punishable by deportation under US immigration law. Federal immigration authorities said they were told by Henss' daughter, who lives in the Atlanta area, that her father fled the US for Germany. He entered the Waffen SS in 1941 and volunteered the following year to become an SS dog handler, serving from 1942 to 1944 at the Dachau and Buchenwald concentration camps, according to immigration court documents.
