F.B.I. Releases Images of Two Suspects in Boston Attack F.B.I. Releases Images of Two Suspects in Boston Attack
(35 minutes later)
BOSTON — The F.B.I. released images on Thursday of two men they said that they would like to question in connection with the Boston Marathon bombings. BOSTON — The F.B.I. on Thursday released still and video images of two suspects in the Boston Marathon bombings — including a man who was seen setting down a backpack at the site of the second blast — and appealed for the public’s help identifying the men.
The images, taken near the finish line of the Marathon when the bombs went off, showed two men — one in a white cap and one in a black cap — that they described as suspects in the bombings, which killed three and injured more than 170 on Monday afternoon. One was seen placing a dark-colored backpack outside the Forum restaurant, the site of the second bombing, just minutes before the explosion, said Richard DesLauriers, the special agent in charge of the F.B.I.'s Boston field office.
“Today we are enlisting the public’s help to identify the two suspects,” said Richard DesLauriers, the special agent in charge of the F.B.I.'s Boston field office. “Today we are enlisting the public’s help to identify the two suspects,” Mr. DesLauriers said at a news conference on Thursday evening in Boston.
Videos and photographs of the men wanted for questioning were posted online at www.fbi.gov. In the video, both men are carrying backpacks, and wearing baseball caps, one a dark cap and one a white cap turned backward. They are walking along Boylston Street. A thin crowd could be seen watching the marathon runners, and the generally festive mood all around them was evident when a spectator in a bright blue jacket, holding several yellow balloons, walked in front of the two men.
The images were located as investigators spent hours since Monday afternoon’s attack poring over surveillance videos from stores near the scenes of the two deadly blasts, as well as footage take on smartphones and by television crews filming the Boston Marathon. “Within the last day or so, through that careful process, we initially developed a single person of interest,” Mr. DesLauriers said. “Not knowing if the individual was acting alone or in concert with others, we obviously worked with extreme purpose to make that determination.”
After a concerted effort, he said, investigators determined that a second suspect had been involved.
Both men appeared to be wearing dark-colored zippered-front jackets. The first, whom Mr. DesLauriers called Suspect 1, wore a dark-colored baseball cap with a white emblem on it and markings on the front, a white T-shirt and tan pants. Visible around the edges of his cap was short dark hair. The man he identified as Suspect 2 wore a white baseball cap backward, with dark-colored pants. He had slightly longer curly hair. The men appeared to be wearing hooded sweatshirts beneath the jackets.
Mr. DesLauriers did not characterize the appearance of the men or offer an opinion as to their possible ethnicity or national origin.
Mr. DesLauriers urged anyone who has seen the men, or who knows who they are, to call 1-800-CALL-FBI (1-800-225-5324).
Earlier Thursday, President Obama flew to Boston and told a service mourning victims of the bombings that “the spirit of this city is undaunted, and the spirit of this country shall remain undimmed.”Earlier Thursday, President Obama flew to Boston and told a service mourning victims of the bombings that “the spirit of this city is undaunted, and the spirit of this country shall remain undimmed.”
“Every one of us has been touched by this attack on your beloved city, every one of us stands with you,” Mr. Obama said in emotional remarks at an interfaith service in Boston’s Cathedral of the Holy Cross, where he mourned those who died, spoke in often personal terms about the city of Boston and ended with a rousing look forward to next year’s Boston Marathon.“Every one of us has been touched by this attack on your beloved city, every one of us stands with you,” Mr. Obama said in emotional remarks at an interfaith service in Boston’s Cathedral of the Holy Cross, where he mourned those who died, spoke in often personal terms about the city of Boston and ended with a rousing look forward to next year’s Boston Marathon.
As the president sought to console a shaken Boston, and a shaken nation, investigators continued to try to find out who was behind the attacks. Investigators have found clear video images of two potential suspects carrying black bags, one at the site of each explosion, a person briefed on the investigation said. The men appeared to capture the interest of law-enforcement officials because of their bags: crime scene investigators recovered portions of a shredded black backpack that they believe carried explosives, the person said, and they were able to determine the brand and model of the bag. The backpack carried by at least one of the men seen in the videos appeared to be similar, the person said.

In Washington, Janet Napolitano, the secretary of the Department of Homeland Security, addressed the attacks, telling a Congressional committee that the authorities are seeking to speak with “individuals” spotted in video footage.In Washington, Janet Napolitano, the secretary of the Department of Homeland Security, addressed the attacks, telling a Congressional committee that the authorities are seeking to speak with “individuals” spotted in video footage.
“We have been collecting video from a variety of sources, as you might imagine, at the finish line of the Boston Marathon,” she said. “There’s lots and lots of video. There is some video that has raised the question of those that the F.B.I. would like to speak with. I wouldn’t characterize them as suspects under the technical term. But we need the public’s help in locating these individuals.” “We have been collecting video from a variety of sources, as you might imagine, at the finish line of the Boston Marathon,” she said. “There’s lots and lots of video.

The interfaith service that Mr. Obama spoke at, “Healing Our City,” brought together Christian, Muslim and Jewish religious leaders, as well as prominent state and local leaders. Mitt Romney, the former governor of Massachusetts and Mr. Obama’s rival in last year’s presidential election, was among the dignitaries as the service.The interfaith service that Mr. Obama spoke at, “Healing Our City,” brought together Christian, Muslim and Jewish religious leaders, as well as prominent state and local leaders.

Boston’s long-serving mayor, Thomas M. Menino, who recently announced that he would not seek a sixth term, got out of the wheelchair he has been using because of a broken leg and stood at the lectern to proclaim, “We are one Boston,” adding that he had never loved the city’s people more. And Gov. Deval L. Patrick of Massachusetts said that “we will have accountability without vengeance, vigilance without fear.”Boston’s long-serving mayor, Thomas M.

Consoling a shaken public has become one of the jobs of American presidents in recent years, from the eulogy President Bill Clinton delivered at the Oklahoma City State Fair Arena after the deadly bombing of the Alfred P. Murrah Federal Building there in 1995 to President George W. Bush’s trip to see the rescue workers at the smoldering ruins of the World Trade Center a few days after the attacks of Sept. 11, 2001, to the eulogies that President Obama has delivered after mass shootings in Tucson and, just months ago, Newtown, Conn.Consoling a shaken public has become one of the jobs of American presidents in recent years, from the eulogy President Bill Clinton delivered at the Oklahoma City State Fair Arena after the deadly bombing of the Alfred P.

At a Senate hearing Thursday morning, the nation’s top intelligence official, James R. Clapper Jr., echoed President Obama’s comments earlier this week that the authorities still do not know whether the attack was a foreign or domestic plot, carried out by one or more individuals or a group.At a Senate hearing Thursday morning, the nation’s top intelligence official, James R.

In a brief interview after the hearing, Mr. Clapper, the director of national intelligence, said all of the nation’s 16 intelligence agencies are supporting the F.B.I.-led investigation, with personnel as well as analytical and technical know-how. “We will bring all the resources that they need,” said Mr. Clapper, who declined to provide details.In a brief interview after the hearing, Mr. Clapper, the director of national intelligence, said all of the nation’s 16 intelligence agencies are supporting the F.B.I.-led investigation, with personnel as well as analytical and technical know-how. “We will bring all the resources that they need,” said Mr. Clapper, who declined to provide details.
Law-enforcement officials said that they had not yet decided whether the authorities will release the video images of the two men and appeal to the public for help, but the person briefed on the investigation said that it was “more likely than not” that they would. Doing so would have advantages and drawbacks. While it could help investigators locate them, it could also alert them that they are being sought — and potentially lead to hundreds of false sightings that could eat up the time of law-enforcement officers. In Boston, Mr. Obama spoke in personal terms about the victims of the bombing and offered prayers for their families. Krystle Campbell, 29, of Medford, Mass., was “always smiling,” he said, noting that her parents were at the service. He said that his prayers were with the family of Lu Lingzi, 23, in China, who had sent her to graduate school at Boston University “so that she could experience all that this city has to offer.” And he spoke about what he called the heartbreaking death Martin Richard, 8, of Dorchester, who was killed in the blast, which also wounded his mother and sister.

If investigators in Boston can find a facial image of sufficient quality from the videos, it could provide a powerful lead. The F.B.I. has been working for several years to create a facial recognition program, and the video of a suspect or suspects could be matched against the bureau’s database of mug shots of about 12 million people who have been arrested, officials said.
If there is no match, investigators can hunt for the suspects’ images in the voluminous videos and photographs from the bombing site that were submitted by members of the public in response to an F.B.I. appeal. That is still a technically difficult task, because the software is most accurate with head-on facial images and can be thrown off even by a smile, specialists said on Wednesday.
Still, “it’s vastly superior to just watching the video,” said Al Shipp, chief executive of 3VR Inc., a company that sells video analytics software. “You can sort through years of video in seconds. That’s the game changer.”
By piecing together more images of suspects and their movements, the F.B.I. might be able to come up with a name. Even without a name, Mr. Shipp said, investigators could program multiple cameras at airports and elsewhere with the suspects’ images so the cameras would send an alert to them if someone resembling a suspect passed by.
While investigators have focused on the images of the possible suspect, they are continuing to pursue a broad range of other avenues, one law enforcement official said.
“We try not to get tunnel vision about it,” the official said, adding, “we’re working a lot of other possibilities.”
