Police and federal agents are looking into striking similarities between yesterday's Times Square bombing and two earlier explosions to determine if there could be a serial bomber at work, the New York Times reports. The device, timing, method of delivery and suspect in the Times Square attack at a military recruitment center strongly resemble those in last year's bombing of the Mexican consulate and the 2005 bombing of the British consulate in Manhattan.
Nobody was hurt in any of the bombings, which all occurred within the same 30-minute pre-dawn time frame. Experts are looking for clues as to what kind of person or group they're dealing with. A male suspect seen cycling away is likely "a frustrated individual trying to send a message—but it is a very confused message," said a criminal profiler.
