During the annual on April 15, 2013, two homemade bombs detonated 12 seconds and 210 yards (190 m) apart at 2:49 p.m., near the finish line of the race, killing three people and injuring several hundred others, including 16 who lost limbs.

Three days later, the (FBI) released images of two suspects, who were later identified as -American brothers and. They killed an, kidnapped a man in his car, and had a shootout with the police in nearby, during which two officers were severely injured, one of whom died a year later. Tamerlan was shot several times, and his brother ran him over while escaping in the stolen car; Tamerlan died soon after.

An unprecedented for Dzhokhar ensued on April 19, with thousands of law enforcement officers searching a 20-block area of Watertown; residents of Watertown and surrounding communities were asked to stay indoors, and the transportation system and most businesses and public places closed. Around 6:00 p.m., a Watertown resident discovered Dzhokhar hiding in a boat in his backyard. He was shot and wounded by police before being taken into custody.

During questioning, Dzhokhar said that he and his brother were motivated by extremist beliefs and the and, that they were self-radicalized and unconnected to any outside terrorist groups, and that he was following his brother's lead. He said they learned to build explosive devices from an of the affiliate in. He also said they had intended to travel to to bomb. On April 8, 2015, he was convicted of 30 charges, including use of a and malicious destruction of property resulting in death. Two months later, he was sentenced to death.



The blasts (red) occurred along the marathon course (dark blue), the first nearer the finish line than the second.

The was run on, April 15, 2013. At 2:49 p.m. (18:49 ), two bombs detonated about 210 yards (190 m) apart at the finish line on Boylston Street near. The first exploded outside at 671–673 Boylston Street at 2:49:43 p.m. At the time of the first explosion, the race clock at the finish line showed 04:09:43, – the elapsed time since the Wave 3 start[] at 10:40 a.m. The second bomb exploded at 2:49:57 p.m., about 14 seconds later and one block farther west at 755. The explosions took place nearly three hours after the winning runner crossed the finish line, but with more than 5,700 runners yet to finish.

Windows on adjacent buildings were blown out but there was no structural damage. Runners continued to cross the line until 2:57 p.m.

Casualties and initial response[]

Rescue workers and medical personnel, on hand as usual for the marathon, gave aid as additional police, fire, and medical units were dispatched, including from surrounding cities as well as private ambulances from all over the state. The explosions killed 3 civilians and injured an estimated 264 others, who were treated at 27 local hospitals. At least 14 people required amputations, with some suffering as a direct result of the blasts.

Police, following emergency plans, diverted arriving runners to and. The nearby and other buildings were evacuated. Police closed a 15-block area around the blast site; this was reduced to a 12-block crime scene on April 16. Boston police commissioner recommended that people stay off the streets.

Dropped bags and packages, abandoned as their owners fled from the blasts, increased uncertainty as to the possible presence of more bombs. There were false reports of more bombs. An unrelated electrical fire at the in nearby was initially feared to be a bomb.

Emergency services at work after the bombing

The airspace over Boston was restricted, and departures halted from Boston's. Some local transit service was halted as well.

The 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 to prevent cell phones from being used as detonators.

The helped concerned friends and family receive information about runners and casualties. The also set up a for people concerned about relatives or acquaintances to contact and a line for people to provide information. activated their disaster service under Boston Marathon Explosions to log known information about missing people as a publicly viewable file.

Due to the closure of several hotels near the blast zone, a number of visitors were left with nowhere to stay; many Boston-area residents opened their homes to them.

The led the investigation, assisted by the, the, the, and the, and they named two official suspects. It was initially believed by some that was behind the attack after escalating tensions and threats with the U.S.

United States government officials stated that there had been no intelligence reports suggesting such an attack. Representative, a member of the, 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."

The father of the two suspects claimed that the FBI had been watching his family, and that they questioned his sons in Cambridge, Massachusetts five times in relation to possible explosions on the streets of Boston.[]

Emptied fireworks from Dzhokhar Tsarnaev's backpack, found in a landfill near the UMass Dartmouth campus

Evidence found near the blast sites included bits of metal, nails, ball bearings, black nylon pieces from a backpack, remains of an electronic circuit board, and wiring. A lid was found on a nearby rooftop. Both of the were manufactured by the bombers. Authorities confirmed that the brothers used bomb-making instructions found in 's magazine. After the suspects were identified, reported that Tamerlan purchased from a fireworks store in.

On April 19, the FBI, Police Department, and Sheriff's Department seized computer equipment from the apartment of the Tamerlans' sister in. On April 24, investigators reported that they had reconstructed the bombs, and believed that they had been triggered by remote controls used for toy cars.

April 18–19 shootings and manhunt[]

Release of suspect photos[]

was immediately adjacent to one of the bombs and lost both legs; he wrote while in the hospital: "Bag, saw the guy, looked right at me". He later gave a detailed description which enabled the photo to be identified and circulated quickly.

At 5:20 p.m. on April 18, the FBI released images of two suspects carrying backpacks, asking the public's help in identifying them. The FBI said that they were doing this in part to limit harm to people wrongly identified by news reports and on social-media. As seen on video, the suspects stayed to observe the chaos after the explosions, then walked away casually. The public sent authorities a deluge of photographs and videos, which were scrutinized by both authorities and online public.

MIT shooting and carjacking[]

Scenes and approximate times of events of April 18–19

A few hours after the photos were released, the Tsarnaev brothers shot Sean A. Collier of the six times in an attempt to steal his gun, which they could not get out because of the holster's retention system. Collier, aged 27, was seated in his police car near the (Building 32) on the campus. He died soon after.

The brothers then a in the neighborhood of Boston. Tamerlan took the owner, Chinese national Dun "Danny" Meng, hostage and told him that he was responsible for the Boston bombing and for killing a police officer. Dzhokhar followed them in the green Honda, later joining them in the Mercedes-Benz. Interrogation later revealed that the brothers "decided spontaneously" that they wanted to go to New York and bomb.

The Tsarnaev brothers forced Meng to use his to obtain 0 in cash. They transferred objects to the Mercedes-Benz and one brother followed it in their Honda Civic, for which an was issued. Meng escaped while the Tsarnaev brothers stopped at a gas station and ran across the street to the gas station, asking the clerk to call 911. His cell phone remained in the vehicle, allowing the police to on Watertown.

Watertown shootout[]

Shortly after midnight on April 19, police officer Joseph Reynolds identified the brothers in the Civic and the stolen SUV. A gunfight followed between the brothers and police arriving at the scene on the 100 block of Laurel St. An estimated 200 to 300 rounds of ammunition were fired and at least one further bomb and several "crude " were thrown.

According to Watertown Police Chief Edward Deveau, the brothers had an " of guns." Tamerlan ran out of ammunition and threw his empty pistol at an officer, who tackled him with help from another officer. Tamerlan's younger brother Dzhokhar then drove the stolen SUV toward Tamerlan and police who unsuccessfully tried to drag Tamerlan out of his path; the car ran over Tamerlan and dragged him a short distance down the street. Dzhokhar abandoned the car half a mile away and fled on foot. Tamerlan Tsarnaev died at 1:35 a.m. at a Boston hospital.[]

Police Officer Richard H. Donohue Jr. was also critically wounded but survived. Boston Police Department officer Dennis Simmonds was injured by a hand grenade and died April 10, 2014. Fifteen other officers were also injured. A later report by Harvard Kennedy School's Program on Crisis Leadership concluded that lack of coordination among police agencies had put the public at excessive risk during the shootout.

Only one firearm was recovered at the scene, a 9 mm pistol with a defaced serial number.

Identification and search for suspects[]

Further information: and

Records on the Honda left at the scene identified the men as two brothers whose family had immigrated to the United States seeking around 2002: 26-year-old Tamerlan Tsarnaev and 19-year-old Dzhokhar "Jahar" Tsarnaev. The FBI released additional photos of the two during the Watertown incident. Early on April 19, Watertown residents received automated calls asking them to stay indoors. That same morning Governor Patrick asked residents of Watertown and adjacent cities and towns to "". residents also received automated calls instructing them to shelter in place.

A 20-block area of Watertown was and residents were told not to leave their homes or answer the door, as officers scoured the area in tactical gear. Helicopters circled the area and teams in moved through in formation, with officers going door to door. On the scene were the FBI, the,,, the Boston and Watertown Police departments, and the. The show of force was the first major field test of the interagency task forces created in the wake of the.

The entire and most Boston taxi services were suspended, as was service to and from Boston. remained open under heightened security. Universities, schools, many businesses, and other facilities were closed as thousands of law enforcement personnel participated in the door-to-door in Watertown, as well as following up other leads, including at the house that the brothers shared in Cambridge, where seven were found

The brothers' father spoke from his home in,, encouraging his son to: "Give up. Give up. You have a bright future ahead of you. Come home to Russia." He continued, "If they killed him, then all hell would break loose." On television, Dzhokhar's uncle from, pleaded with him to turn himself in.

Post-capture celebrations in Boston's student-heavy neighborhood

David Henneberry, a Watertown resident outside the search area, noticed that the tarp was loose on his parked boat on the evening of April 19, two hours after the shelter-in-place order had been lifted. He then saw a body lying inside the boat in a pool of blood. Authorities surrounded the boat and a police helicopter verified movement through a device. The figure inside the boat started poking at the tarp, and police shot at the boat.

According to Boston Police Commissioner Ed Davis and Watertown Police Chief Deveau, Dzhokhar Tsarnaev was shooting at police from inside the boat, "exchanging fire for an hour". A subsequent report indicated that the firing lasted for a shorter time. The suspect was found to have no weapon when he was captured. He was arrested at 8:42 p.m. and taken to, where he was listed in with gunshot wounds to the head, neck, legs, and hand.

Initial reports that the neck wound represented a suicide attempt were contradicted by his being unarmed. The situation was chaotic according to a police source quoted by the, and the firing of weapons occurred during "the fog of war". A subsequent review by the Commonwealth of Massachusetts provided this more specific summary: "One officer fired his weapon without appropriate authority in response to perceived movement in the boat, and surrounding officers followed suit in a round of 'contagious fire', assuming they were being fired on by the suspect. Weapons continued to be fired for several seconds until on scene supervisors ordered a ceasefire and regained control of the scene. The unauthorized shots created another dangerous crossfire situation".

Legal proceedings[]


United States Senators,,, and, and Representative suggested that Dzhokhar Tsarnaev, a U.S. citizen, should be tried as an rather than as a criminal, potentially preventing him from obtaining. Others said that doing so would be illegal, including prominent American legal scholar and lawyer, and would jeopardize the prosecution. The government decided to try Dzhokhar in the federal criminal court system and not as an enemy combatant.

Dzhokhar was questioned for 16 hours by investigators but stopped communicating with them on the night of April 22 after Judge Marianne Bowler read him a. Dzhokhar had not previously been given a Miranda warning, as federal law enforcement officials invoked the warning's. This raised doubts whether his statements during this investigation would be admissible as evidence and led to a debate surrounding Miranda rights.

Charges and detention[]

Dzhokhar Tsarnaev in a court holding cell on July 10, 2013

On April 22, 2013, formal criminal charges were brought against Tsarnaev in the during a bedside hearing while he was hospitalized. He was charged with use of a and with malicious destruction of property resulting in death. Some of the charges carry potential sentences of or the. Tsarnaev was judged to be awake, mentally competent, and lucid, and he responded to most questions by nodding. The judge asked him whether he was able to afford an attorney and he said no; he was represented by the 's office. On April 26, Dzhohkar Tsarnaev was moved from Beth Israel Deaconess Medical Center to the at, about 40 miles (64 km) from Boston. FMC Devens is a federal prison medical facility at a former Army base where he was held in solitary confinement at a segregated housing unit with 23-hour-per-day lockdown.

On July 10, 2013, Tsarnaev pleaded not guilty to 30 charges in his first public court appearance, including a murder charge for MIT police officer Sean Collier. He was back in court for a status hearing on September 23, and his lawyers requested more time to prepare their defense. On October 2, Tsarnaev's attorneys asked the court to lift the (SAMs) imposed by Attorney General Holder in August, saying that the measures had left Tsarnaev unduly isolated from communication with his family and lawyers, and that no evidence suggested that he posed a future threat.

Trial and sentencing[]

Main article:

Jury selection began on January 5, 2015 and was completed on March 3, with a jury consisting of eight men and ten women (including six alternates). The trial began on March 4 with Assistant U.S. Attorney William Weinreb describing the bombing and painting Dzhokhar as "a soldier in a holy war against Americans" whose motive was "reaching paradise". He called the brothers equal participants.

Defense attorney admitted that Dzhokhar Tsarnaev had placed the second bomb and was present at the murder of Sean Collier, the carjacking of Dun Meng, and the Watertown shootout, but she emphasized the influence that his older brother had on him, portraying him as a follower. Between March 4 and 30, prosecutors called more than 90 witnesses, including bombing survivors who described losing limbs in the attack, and the government rested its case on March 30. The defense rested as well on March 31, after calling four witnesses.

Tsarnaev was found guilty on all 30 counts on April 8. The sentencing phase of the trial began April 21, and a further verdict was reached on May 15 recommending that he be put to death. Tsarnaev was sentenced to death on June 24, after apologizing to the victims.

Motives and backgrounds of Tsarnaev brothers[]


According to FBI interrogators, Dzhokhar and his brother were motivated by Islamic beliefs but "were not connected to any known terrorist groups", instead learning to build explosive weapons from an online magazine published by affiliates in Yemen. They further alleged that "[Dzhokhar and] his brother considered suicide attacks and striking [the Boston Pops Fireworks Spectacular] on the Fourth of July; but ultimately decided to use pressure cooker bombs (capable of remote detonation) and other IEDs." Fox News reported that the brothers "chose the prestigious race as a 'target of opportunity'... [after] the building of the bombs came together more quickly than expected".

Dzhokhar said that he and his brother wanted to defend Islam from the U.S., accusing the U.S. of conducting the and against Muslims. A CBS report revealed that Dzhokhar had scrawled a note with a marker on the interior wall of the boat where he was hiding; the note stated that the bombings were "retribution for U.S. military action in Afghanistan and Iraq", and called the Boston victims "", "in the same way innocent victims have been collateral damage in U.S. wars around the world." Photographs of the note were later used in the trial.

Some political science and public policy writers suggest that Islam may have played a secondary role in the attacks. These writers theorize that the primary motives might have been sympathy towards the political aspirations in the Caucasus region and Tamerlan's inability to become fully integrated into American society. According to the, a law enforcement official said that Dzhokhar "did not seem as bothered about America's role in the Muslim world" as his brother Tamerlan had been. Dzhokhar identified Tamerlan as the "driving force" behind the bombing, and said that his brother had only recently recruited him to help.

Some journalists and Dzhokhar Tsarnaev's defense attorney have suggested that the FBI may have recruited or attempted to recruit Tamerlan Tsarnaev as an informant.

The FBI was informed by the Russian (FSB) in 2011 that he was a "follower of radical Islam." In response, the FBI interviewed Tamerlan and his family and searched databases, but they did not find any evidence of "terrorism activity, domestic or foreign." During the 2012 trip to Dagestan, Tamerlan was reportedly a frequent visitor at a mosque on Kotrova Street in, believed by the to be linked with radical Islam.

The local district attorney said that it appeared that the killer and the victims knew each other, and that the murders were not random. Tamerlan Tsarnaev had previously described murder victim Brendan Mess as his "best friend." After the bombing and subsequent revelations of Tsarnaev's personal life, the Waltham murders case was reexamined in April 2013 with Tsarnaev as a new suspect. Both and The New York Times have reported that there is strong evidence which implicates Tsarnaev in this triple homicide.

Some analysts claim that the Tsarnaev's mother Zubeidat Tsarnaeva is a radical extremist and supporter of jihad who influenced her sons' behavior. This prompted the Russian government to warn the U.S. government on two occasions about the family's behavior. Both Tamerlan and his mother were placed on a terrorism watch list about 18 months before the bombing took place.

Victims of the bombing are remembered at Copley Square in Boston.

Numerous sporting events, concerts, and other public entertainment were postponed or cancelled in the days following the bombing. The public transit system was under heavy National Guard and police presence and it was shut down a second time April 19 during the manhunt.

In the days after the bombing, makeshift memorials began to spring up along the cordoned-off area surrounding Boylston Street. The largest was located on Arlington Street, the easternmost edge of the barricades, starting with flowers, tokens, and T-shirts. In June, the Makeshift Memorial located in Copley Square was taken down and the memorial objects located there were moved to the archives in West Roxbury for cleaning, fumigation, and archiving.

One study conducted by the Institute for Public Service at in Boston, Massachusetts, records the mental health and emotional response of various survivors, for three years following the bombing. In doing so, it reviews the kinds of aid that were available in local hospitals and gives advice as to how a person or community may be healed.

This study also mentions that after realizing the under coverage of people in the city being killed or injured on a daily basis, the city of Boston "applied for and received a grant from The Rockefeller Foundation to be part of their 100 resilient cities network and to develop a cross cutting resilience strategy".

However, there was rising online and locally in the weeks following the bombing, causing distress in the local community and leaving some afraid of going out.


President addressed the nation after the attack. He said that the perpetrators were still unknown, but that the government would "get to the bottom of this" and that those responsible "will feel the full weight of justice".

Organizers of the, which was held six days after the Boston bombing, reviewed security arrangements for their event. Hundreds of extra police officers were drafted in to provide a greater presence on the streets, and a record 700,000 spectators lined the streets. Runners in London observed a 30-second silence in respect for the victims of Boston shortly before the race began, and many runners wore black ribbons on their vests. Organizers also pledged to donate US to a fund for Boston Marathon victims for every person who finished the race.

Organizers of the 2013, which was held on April 21, 2013, donated from every late entry for the race to help victims of the bombing at the Boston Marathon. Jamie Pitblado, vice-president of promotions for The Vancouver Sun and The Province, said the money would go to One Fund Boston, an official charity that collected donations for the victims and their families. Sun Run organizers raised anywhere from,000 to,000. There were over 48,000 participants, many dressed in blue and yellow (Boston colors) with others wearing Boston Red Sox caps.

, ambassador of the Czech Republic, released a statement after noticing much confusion on Facebook and Twitter between his nation and the Chechen Republic. "The Czech Republic and Chechnya are two very different entities – the Czech Republic is a Central European country; Chechnya is a part of the Russian Federation."

Security was also stepped up in Singapore in response to online threats made on attacking several locations in the city-state and the Singapore Marathon in December. Two suspects were investigated and one was eventually arrested for making false bomb threats.

Russian reaction[]

The said special attention would be paid to security at upcoming international sports events in Russia, including the. According to the Russian embassy in the U.S., President condemned the bombing as a "barbaric crime" and "stressed that the Russian Federation will be ready, if necessary, to assist in the U.S. authorities' investigation." He urged closer cooperation of security services with Western partners but other Russian authorities and mass media blamed the U.S. authorities for negligence as they warned the U.S. of the Tsarnaevs. Moreover Russian authorities and mass media since the spring of 2014 blame the United States for politically motivated false information about the lack of response from Russian authorities after subsequent U.S. requests.[] As proof a letter from the Russian (FSB) was shown to the members of an official U.S. Congressional delegation to Moscow during their visit. This letter with information about Tsarnaev (including his biography details, connections and phone number) had been sent from the FSB to the FBI and CIA during March 2011.

Republican U.S. Senators and reported that Russian authorities had separately asked both the FBI (at least twice: during March and November 2011) and the CIA (September 2011) to look carefully into Tamerlan Tsarnaev and provide more information about him back to Russia. Russian (FSB) secretly recorded phone conversations between and his mother (they vaguely and indirectly discussed jihad) and sent these to the FBI as evidence of possible extremist links within the family. However, while Russia offered US intelligence services warnings that Tsarnaev planned to link up with extremist groups abroad, an FBI investigation yielded no evidence to support those claims at the time. In addition, subsequent U.S. requests for additional information about Tsarnaev went unanswered by the Russians.

Chechen reactions[]

On April 19, 2013, the press-secretary of the,, issued a statement that, inter alia, read: "The Boston bombing suspects have nothing to do with Chechnya". On the same day, Kadyrov was reported by to have written on :

Any attempt to make a link between Chechnya and the Tsarnaevs, if they are guilty, is in vain. They grew up in the U.S., their views and beliefs were formed there. The roots of evil must be searched for in America. The whole world must battle with terrorism. We know this better than anyone. We wish recover [] to all the victims and share Americans' feeling of sorrow.

, head of the secular wing of the, now in exile in London, condemned the bombing as "terrorist" and expressed condolences to the families of the victims. Zakayev denied that the bombers were in any way representative of the Chechen people, saying that "the Chechen people never had and can not have any hostile feelings toward the United States and its citizens."

The, the Islamist organization in both Chechnya and Dagestan, denied any link to the bombing or the Tsarnaev brothers and stated that it was at war with Russia, not the United States. It also said that it had sworn off violence against civilians since 2012.

Criticism of "shelter-in-place" directive and house-to-house searches[]

During the manhunt for the perpetrators of the bombing, Governor said "we are asking people to shelter in place." The request was highly effective; most people stayed home, causing Boston, Watertown, and Cambridge to come to a virtual standstill. According to magazine, "media described residents complying with a 'lockdown order,' but in reality the governor's security measure was a request.", emeritus director of the Center on Law, Ethics and National Security at Duke Law School, said that the shelter-in-place request was voluntary.

The shelter-in-place directive was criticized by some commentators. Michael Cohen of said that Americans have little experience with daily terrorism compared to some countries and "are more primed to … assume the absolute worst." Cohen wrote that it was not the first time dangerous murderers have been on the loose in a large American city (citing in 2013 and the in 2002), but noted that "lockdown" measures were not used in those cases. Former congressman and presidential candidate, criticized what he described as a "military-style takeover of parts of Boston" during the investigation and wrote that "this unprecedented move should frighten us as much or more than the attack itself."

's Chemi Salev wrote that "in terms of cost-benefit analysis, from the evil terrorist's point of view, the Boylston Street bombings and their aftermath can only be viewed as a resounding triumph" since the "relatively amateurish" terrorists managed to intimidate a vast number of people and got a maximum amount of publicity. Responding to Salev in The New York Times, commented that the massive manhunt operation might deter other amateur terrorists, but not hard-core terrorists such as. Douthat argued that out-of-the-ordinary measures can only be used when terrorism itself is out-of-the-ordinary: if attacks started to occur more often, people would not be as willing to comply with shelter-in-place commands, yet once a terrorist has been hunted with such an operation, it is hard to justify why such measures should not be taken the next time.

The and some news outlets questioned the constitutionality of the door-to-door searches conducted by law enforcement officers looking for Dzhokhar Tsarnaev.

Conflicting reports[]

On the afternoon of the bombing, the reported that a suspect, a Saudi Arabian male, was under guard and being questioned at a Boston hospital. That evening, Boston Police Commissioner Ed Davis said that there had not been an arrest. The Post did not retract its story about the suspect, leading to widespread reports by CBS News, CNN, and other media that a Middle Eastern suspect was in custody. The day after the bombing, a majority of outlets were reporting that the Saudi was a witness, not a suspect.

The New York Post on its April 18 front page showed two men, and said they were being sought by the authorities. The two were not the ones being sought as suspects. They were a 17-year-old boy and his track coach. The boy, from, turned himself over to the police immediately and was cleared after a 20-minute interview in which they advised him to deactivate his Facebook account.New York Post editor stated, "We stand by our story. The image was emailed to law enforcement agencies yesterday afternoon seeking information about these men, as our story reported. We did not identify them as suspects." The two were implied to be possible suspects via on the websites and.

Several other people were mistakenly identified as suspects. Two of those wrongly identified as suspects on Reddit were a 17-year-old track star and, a student missing since March. Tripathi was found dead on April 23 in the.

On April 17, the FBI released the following statement:

Contrary to widespread reporting, no arrest has been made in connection with the Boston Marathon attack. Over the past day and a half, there have been a number of press reports based on information from unofficial sources that has been inaccurate. Since these stories often have unintended consequences, we ask the media, particularly at this early stage of the investigation, to exercise caution and attempt to verify information through appropriate official channels before reporting.

The decision to release the photos of the Tsarnaev brothers was made in part to limit damage done to those misidentified on the Internet and by the media, and to address concerns over maintaining control of the manhunt.

Film adaptation[]

A film about the Boston Marathon bombing and subsequent manhunt,, was released in December 2016. Another film,, which chronicles survivor, was released in September 2017.
