Investigators mull releasing photos from Boston Marathon finish line

FBI investigators have been scouring video and still images taken around the finish line, where two bombs exploded during Monday's race, killing three and injuring 176. Authorities believe at least one of the bombs was a sealed pressure cooker laden with explosives and shrapnel, and may have been concealed in a backpack.
'
Investigators are believed to be weighing the advantages of releasing the photos and enlisting the public's aid in finding possible suspects and doing anything that might jeopardize the investigation. Amateur sleuths around the world have been examining widely circulated photos from the crowd, isolating on people with backpacks, but officials have warned against such speculation.

A mangled pressure cooker lid found atop a nearby building is believed to have been part of one bomb, and it and other pieces were being analyzed at an FBI lab. A battery and several pieces of shrapnel were also recovered and undergoing analysis. Fox News learned that the circuit board suspected of being used to detonate at least one of the bombs has been recovered, and that FBI investigators were also analyzing cellphone tower records to identify positive hits for signs of calls that may have been placed to trigger both explosions remotely.
Investigators believe one, or possibly two, pressure cookers were packed with explosives and shrapnel and hidden in backpacks to be left amid the crowd.

According to a FBI and Department of Homeland Security bulletin, the deadly shrapnel that caused the deaths -- including of an 8-year-old boy, and critical injuries to 17 -- included nails, BBs and ball bearings. The other device "was also housed in a metal container, but investigators could not say if that was also a pressure cooker.
Pressure cooker bombs have been used in high-profile bombings in India, Pakistan and Afghanistan, and have been touted in the Al Qaeda in Yemen's online propaganda magazine Inspire and in the "The Anarchist Cookbook."
News of the images came as President Obama plans to visit Boston on Thursday to attend an interfaith service in honor of the three people killed and more than 170 injured when twin bombs ripped through the crowd Monday at the Boston Marathon.
The president is scheduled to speak at the "Healing Our City" service. He may also meet with some of those injured, as well as the first responders who rushed toward the blast to help the scores of runners and spectators.
'
Obama has traveled four times to cities reeling from mass violence, most recently in December after the schoolhouse shooting in Newtown, Conn.
Monday's horror unfolded just before 3 p.m., shattering a festive atmosphere several hours after the legendary race began on the city's 238th annual Patriots' Day. In the aftermath, officials found bomb remnants, shrapnel and shredded backpacks believed to have concealed the deadly payloads.
'
Richard DesLauriers, FBI agent in charge in Boston, confirmed at a press conference investigators had found pieces of black nylon from a bag or backpack and fragments of BBs and nails, possibly contained in a pressure cooker. He said the items were sent to the FBI laboratory at Quantico, Va., for analysis.
'
The FBI also plans to reconstruct the devices at their headquarters in Quantico, according to MyFoxBoston.com.
Investigators are also examining if the bombs could have been assembled near the scene of the explosions, The Wall Street Journal reports, quoting a law enforcement official. The official says this possibility is being considered because transporting improvised devices over a significant distance could trigger a premature detonation.
'
Scores of victims remained in hospitals, but the death toll has not risen since Monday.
Boston Medical Center held a press conference Thursday morning and said it saw a total of 23 patients. Doctors there performed 16 operations within the first several hours and, on Wednesday, performed 13 reoperations. There were four patients released since the explosion and one remains in critical condition, the doctors said. Ten patients are in serious condition.
'
The doctors credited some recent advances to dealing with trauma from techniques used in Iraq and Afghanistan. For one, doctors and first responders used component therapy instead of a lot of IV fluids. Component therapy can be used to promote blood clotting.
Anyone with information on the bombings is being urged to call Boston authorities at 1-800-494-TIPS.
