The Shin Bet security service agents who arrived at the home of the terrorist's family in Sur Baher in East Jerusalem, are now looking for clues as to the motive behind the deed. They will try to find out when was the last time Duwiyat visited a mosque, and whether he heard there unusual words of incitement against Israel. Some of the terrorists who carried out attacks in recent years of their own volition, and with no links to any organization, had been driven to take action out of deep religious feelings.
