During the 2013 Boston Marathon on April 15, 2013, two pressure cooker bombs exploded, killing 3 people and injuring 183 others.The bombs had been placed near the finish line, along Boylston Street. They detonated at 2:49 p.m. EDT (18:49 UTC), 12 seconds apart. No warnings had been given, and no one has been arrested or claimed responsibility for the bombing. The FBI is leading an investigation.
On Patriots' Day, Monday, April 15, 2013, the annual Boston Marathon began without any indications of an imminent attack. Officials swept the area for bombs twice before the explosions; one of the sweeps occurred an hour before the bombs went off. People were able to come and go freely, and carry items in and out of the area.
At 2:49 p.m. EDT (18:49 UTC), two bombs detonated on Boylston Street near Copley Square about 200 yards (180 m) apart, just before the finish line.The first exploded outside Marathon Sports at 671–673 Boylston Street at 2:49:44 p.m. EDT; the second, one block farther west at 755 Boylston Street at 2:49:57 p.m. EDT.Described as pressure cooker bombs,witch is thought to be made using Fagor Duo Stainless Steel Pressure Cooker , they were improvised explosive devices constructed from pressure cookers, explosives, bits of metal, and bearing balls placed in black nylon duffel bags or backpacks. About 12 seconds passed between the two blasts. At the time of the first explosion, the race clock at the finish line showed 04:09:43.
The bombs detonated about two hours after the winner crossed the finish line;more than 5,700 runners had yet to finish. Some runners continued to cross the line until 2:57 p.m., eight minutes after the explosions. The blasts blew out windows on adjacent buildings, but did no other structural damage.
During a news conference two hours after the bombings, Massachusetts Governor Deval Patrick said there were "only two explosive devices", the two that exploded. Initial reports conflicted over whether additional bombs were found, with numerous suspicious packages or bags initially discovered. TheBoston Police Bomb Squad initially said that they were going to perform a controlled explosion of one of the packages found, on the 600 block ofBoylston Street,but later said no devices other than the two exploding bombs were found.
Victims
The toll from the bombings was 3 people killed and 183 injured. Many of the injuries were grievous, requiring intensive care, and appeared to be "war-like injuries" of mutilation, shrapnel wounds, and amputations. The trauma surgery chief at Boston Medical Center said: “We see patients like this, with mangled extremities, but we don’t see 16 of them at the same time, and we don’t see patients from blast injuries.
Deaths
Three spectators were killed in the bombings: Krystle M. Campbell, 29, a female restaurant manager from Medford, Massachusetts; Lü Lingzi (simplified Chinese: 吕令子; traditional Chinese: 呂令子), 23, a female Chinese national and Boston University graduate student from Shenyang,Liaoning; and Martin Richard, 8, a boy from the Dorchester neighborhood of Boston.
Injuries
Ten local hospitals treated more than 170 people. At least 15 of the injured were in critical condition on April 16, including 2 children.
Many victims suffered lower leg injuries and shrapnel wounds, which indicated the devices were low to the ground. Some suffered ruptured eardrums. At least 13 of the injured suffered severed limbs.Doctors described removing "ball-bearing type" metallic beads a little larger than BBs, and small carpenter-type nails about 1 to 2.5 centimeters (0.4 to 1.0 in) long. Similar objects were found at the scene. The New York Times stated that, according to doctors, because the bombs were low to the ground, the injuries mainly affected legs and feet instead of abdomens, chests, and heads, and as a result few deaths occurred.
Responses
Rescue workers, medical personnel on hand to assist runners, bystanders, and runners rushed to help the wounded in the immediate aftermath.
The marathon was halted abruptly. Police, following emergency plans, diverted the remaining runners away from the finish line to Boston Common andKenmore Square. The nearby Lenox Hotel was also evacuated. Police closed down a 15-block area around the blast site; this was reduced to a 12-block crime scene on April 16. Massachusetts Army National Guard soldiers already on scene joined local authorities in rendering aid.Bomb squads searched the area. Many bystanders had dropped backpacks and other bags as they fled, requiring each to be treated as a potential bomb. Boston police commissioner Ed Davis recommended that people stay off the streets.
As a precaution, the FAA restricted airspace over Boston, and issued a temporary ground stop for Boston'sLogan International Airport. Some Massachusetts Bay Transportation Authority service was halted.Several cities in Massachusetts and other states put their police forces on alert.U.S. Attorney GeneralEric Holder directed that the "full resources" of the U.S. Department of Justice be brought to bear on investigating the explosions.The Navy sent one of its bomb-disposal units to Boston to help local authorities.
The Massachusetts Emergency Management Agency suggested people trying to contact those in the vicinity use text messaging, instead of voice calls, because of crowded cellphone lines.Cellphone service in Boston was congested but remained in operation, despite some local media reports stating that cell service was shut down.
The American Red Cross helped concerned friends and family receive information about runners and casualties.The Boston Police Departmentalso set up a helpline for people concerned about relatives or acquaintances to contact and a line for people to provide information.Google Person Finder activated their disaster service under Boston Marathon Explosions to log known information about missing persons as a publicly viewable file.
Due to the closure of several hotels near the blast zone, some out-of-town visitors were left with nowhere to stay; many Boston-area residents opened their homes to them.
Investigation
The Federal Bureau of Investigation, which is investigating the attack along with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), theCentral Intelligence Agency, and the National Counterterrorism Center, is treating the bombings as a terrorist attack, though no perpetrator has officially been identified.
At a press conference held at 6:00 p.m. on the day of the bombings, Boston police commissioner Edward F. Davis told reporters that no suspect was in custody. Though not treated as suspects, several people who were near the scene of the blast and the surrounding area were taken into custodyand questioned about the bombings, including a Saudi man that police stopped as he was walking away from the explosion, and detained when some of his responses to questions "made them uncomfortable". Early in the morning on April 16, law enforcement officials searched a residence in the nearby Boston suburb of Revere, the home of the Saudi man, who had been injured by shrapnel and was considered to be a "person of interest". CNN also reported that the man was found to have no connection to the attack, with an unnamed U.S. official saying "he was just at the wrong place at the wrong time."
United States government officials stated that there had been no intelligence reports that indicated such a bombing would take place. RepresentativePeter King, member of the House Intelligence Committee said: "I received two top secret briefings last week on the current threat levels in the United States, and there was no evidence of this at all.
A person who was briefed on the investigation said at least one of the devices was made from a pressure cooker packed with shards of metal, nails, and ball bearings to inflict maximum casualties and was placed in a backpack. The lid of one pressure cooker was found on a nearby rooftop. Investigators have found remains of an electronic circuit board that was possibly used in the timer of the bomb.Gun powder was most likely used in the explosive devices.
The president of Boston's City Council, Stephen J. Murphy, told reporters on Wednesday, April 17, 2013, that a surveillance tape showing a man depositing a black backpack near the location of the explosion had been discovered.
