An 85-year-old man accused of being a Nazi dog handler has returned to Germany rather than fight to stay in the US, a federal prosecutor told a judge at a deportation hearing. Paul Henss was accused of training and handling attack dogs at the Dachau and Buchenwald concentration camps. US Immigration Judge J. Dan Pelletier ordered him deported after a 30-minute hearing Tuesday conducted without Henss or an attorney on his behalf present. Henss left Friday for his native Germany, Edgar Chen, an attorney with the Department of Justice's Office of Special Investigations, told the judge. The government said Henss, a German citizen, assisted in Nazi persecution of Jews, a crime punishable by deportation under US immigration law. He acknowledged to reporters last month at his home in suburban Lawrenceville that he had trained dogs but said he fought in Russia and never set foot inside Dachau or Buchenwald.
