(HAMBURG, Germany) — From his post as a teenage SS private in a watchtower in Nazi Germany’s Stutthof concentration camp, Bruno Dey could hear the screams of Jews dying in the gas chamber. And, Dey later told investigators, the carting of their lifeless bodies to the camp’s crematorium was a daily sight. More than seven decades later, Dey went on trial Thursday on 5,230 counts of accessory to murder in Hamburg state court.
