On the night of January 20/21, 1941, during the Legionnaires' rebellion, David was kidnapped from his home by an Iron Guard squad and brought to the Bucharest Police Headquarters, where he was severely beaten and ultimately assassinated. According to the deposition of one of the squad members, he was brought by car near Pantelimon, brought out in a field and, after refusing to divulge information regarding the communist organisations, shot in the head at point blank. His body, severely mutilated, with the left arm torn out, was found only four weeks later.
