Photos yield 2 possible suspects in explosions

BOSTON

Authorities have obtained clear images of the faces of two men with backpacks who they believe were acting suspiciously around the time of the Boston Marathon bombings, a potential breakthrough in the search to find who planted the deadly devices, sources familiar with the investigation said Wednesday.

A department store surveillance camera caught an image of at least one of the men leaving a backpack near the finish line, a federal law enforcement official said.

Another official briefed on the investigation said the image that shows two men is the first indication that more than one bomber may have been responsible for the attacks that killed three people and injured more than 170 at Monday’s race.

The men were singled out because of their demeanor and the way in which they reacted to the bomb blasts, said these officials, who could not be identified because they were not authorized to discuss the investigation publicly. Neither would say how close authorities were to identifying the two.

The photographic evidence adds to physical evidence already gathered at the scene, including parts of a pressure cooker probably used in the two bombs that went off as hundreds of runners were still streaming in five hours into the race.

Authorities are relying not only on extensive surveillance video but a flood of photos and videos sent in by spectators, office workers and others who were at the disaster scene near Copley Square.

“I think that this will go down in U.S. history as the most videotaped bombing in history,” said Tom Thurman, who formerly headed the FBI’s Bomb Data Center and helped investigate the 1988 bombing of Pan Am Flight 103 over Lockerbie, Scotland, and the 1993 bombing of the World Trade Center.

President Barack Obama is scheduled to speak today at an interfaith service here for the victims, 59 of whom are still hospitalized, with 10 in critical condition. The third victim killed has been identified as Lu Lingzi, 23, a Chinese national who was a Boston University graduate student in statistics.

Boston Mayor Thomas Menino and Massachusetts Gov. Deval Patrick announced that attorney Kenneth Feinberg would administer One Fund Boston, a fund set up to aid those affected by the attacks. Feinberg oversaw similar funds for victims of the Sept. 11 attacks and the 2010 BP oil spill.

The disclosures about the photos emerged on a dizzying day of conflicting reports in which a number of news agencies initially reported that a suspect had been identified and arrested, and was supposedly scheduled for a court appearance.

Hundreds of reporters and spectators gathered outside the Joseph Moakley federal courthouse near Boston’s Seaport district, which was briefly evacuated for a bomb threat, even as the FBI and the Boston Police Department denied anyone had been taken into custody.

Federal officials cautioned that the full work of building a case could take time. Law enforcement officers now have access to sophisticated software tools that can use algorithms to search video for specific patterns — colors of clothing, movement or objects, analysts say. The federal Department of Homeland Security has invested heavily in facial recognition software. But it can be tedious work.

“The qu estion that is most often asked is, is there a button we can push to make this happen as quickly as the general public thinks we can, from watching television and movies,” said Larry Compton, operations manager at Forensic Video Solutions Inc., a firm that serves as a consultant to law enforcement.

“The answer is no. These tools and techniques are really designed to focus the analysts,” he said.

The department store video can be compared with images gleaned from more than 10 trillion bytes of data gathered from other sources, including gas stations and ATM and traffic cameras to see where a person of interest might have been before and after the attack, said one retired federal agent.

But security videos are typically low-resolution and don’t offer a lot of visual detail, experts say, which helps explain why authorities have appealed to the public for photos and cellphone videos — images with much higher resolution.

“Then you can really blow it up and zoom on in,” said Lance McVickar, president of Lawdio Inc. of Fairmount, N.Y., who has also served as a video consultant in federal investigations. “And a lot of them do time-stamping....You find a picture with a bag not there and then a picture with a bag there — and then a photo of a person dropping the bag.”
