Dr. Mallard proposes that the man who was in the store was a suicide bomber. Two men, Wahid and Malik, come to the store, telling the team that they are part of The Muslim Coalition for Peace that works there. Ziva finds the head of the suicide bomber, and Wahid and Malik tell the team that it's the head of their chapter president, Yazid, who was planning a conference. Later, back at the crime scene, DiNozzo finds an escape route through the wall, which the terrorist used. The team later finds that Ducky was right in saying their tip had died the day before and the terrorist had used a computer to digitally make it sound like the actual person to lead the team into a trap.
