Investigators worked with medical teams Saturday to reconstruct the remains of the culprits believed to have set off explosions that tore through the restaurants of the J.W. Marriott and Ritz-Carlton at breakfast time the day before. Seven were killed, plus the two suspected attackers, and 50 wounded, many of them foreigners. The method, target and type of bombs used in Friday's attacks immediately raised suspicions of involvement by the Jemaah Islamiyah terror group and Noordin M. Top.
