One of the two chief planners of the attack, Qais Adwan, a Hamas member who was involved in numerous attacks in which a total of 77 people were killed, was killed in a shootout with the IDF during Operation Defensive Shield. In May 2002, Israeli forces arrested the other chief planner, Abbas al-Sayed. On 22 September 2005, al-Sayed was convicted of the Passover attack and also of ordering the May 2001 bombing of a Netanya mall. He received 35 life sentences for each murder victim and additional time for those who were wounded.
