FBI releases images of two suspects in Boston Marathon bombings DesLauriers said at a Boston news conference that investigators identified one person of interest in the past day and that the breakthrough led to a second. He appealed for the public's help in identifying the men. The photos put faces on suspected perpetrators whose identity and whereabouts have been the subject of endless, often erroneous, speculation since the remotely detonated bombs killed three people and injured 176 near the race finish line Monday. But the imagery released by the FBI , while it seemed to rule out a lone wolf, did not answer the question as to whether the bombing was a terrorist attack associated with a foreign or domestic extremist group or whether there was another, unknown agenda. The man identified by the FBI as "Suspect 1" was carrying what appeared to be a heavy dark-colored backpack. He wore dark glasses, a black baseball hat pulled low, chino pants, a white T-shirt and a dark jacket. Des­Laur­iers said he was not captured on video dropping the backpack he was carrying. "Suspect 2," wearing a white baseball hat backward and dark clothing and carrying a light-colored backpack, was videotaped setting down what the FBI believes was the bomb that caused the second blast outside the Forum restaurant on Boylston Street near the finish line. The man then walked west on Boylston, but federal officials said he remained in the general area until the bomb went off. The well-known restaurant was hosting a race-watching party at the time, and DesLauriers appealed to people who were there and who have not yet come forward to contact the FBI. Both suspects looked like typical marathon spectators. In the snippets of released video, they appeared unhurried as they moved along the street. The video showed both men walking in single file in close proximity on Boylston Street shortly before the explosions, and DesLauriers said they appeared to investigators to be associated with each other. "Somebody out there knows these individuals," said DesLauriers. He said the video and photos were posted on the FBI Web site, www.fbi.gov. Officials said traffic on the Web site reached record levels after the images were released, causing a temporary slowdown. DesLauriers said locating the suspects was the "highest priority" of investigators, but he cautioned the public not to attempt to confront or apprehend them, but to instead immediately call the FBI or police. Officials hope the photos will be seen worldwide. In the three days since the bombing, the suspects may have left the Boston area and could well have left the country, said a law enforcement official who spoke anonymously because he was not authorized to discuss the case publicly.
