During the Boston Marathon on April 15, 2013, two pressure cooker bombs exploded at 2:49 pm EDT (18:49 UTC), killing 3 people and injuring 264. The bombs exploded about 13 seconds and 210 yards (190 m) apart, near the finish line on Boylston Street. The Federal Bureau of Investigation (FBI) took over the investigation, and on April 18, released photographs and surveillance video of two suspects. The suspects were identified later that day as the Chechen brothers Dzhokhar and Tamerlan Tsarnaev.
Shortly after the FBI released the images, the suspects allegedly killed an MIT police officer, carjacked an SUV, and initiated an exchange of gunfire with the police in Watertown, Massachusetts. During the exchange, an MBTA police officer was critically injured, Tamerlan Tsarnaev was killed, and Dzhokhar Tsarnaev was injured and escaped. An unprecedented manhunt ensued on April 19, with thousands of police searching a 20-block area of Watertown.
During the manhunt, the authorities asked residents of Watertown and surrounding areas, including Boston, to stay indoors, and the public transportation system and most businesses and public institutions were shut down, resulting in a deserted urban environment of historic size and duration. Around 7 pm, shortly after the "shelter-in-place" advisory was rescinded, a Watertown resident discovered the suspect hiding in a boat in his back yard. Dzhokhar was arrested and taken to a hospital shortly thereafter.
During an initial interrogation in the hospital, Dzhokhar said Tamerlan was the mastermind. He said they were motivated by extremist Islamist beliefs and the wars in Iraq and Afghanistan, and that they were self-radicalized and unconnected to any outside terrorist groups, but that they had learned how to build explosive devices from an online magazine of the al-Qaeda affiliate in Yemen. He said that he and his brother had decided after the Boston bombings to travel to New York City to bomb Times Square. Dzhokhar was charged on April 22, while still in the hospital, with use of a weapon of mass destruction and malicious destruction of property resulting in death.
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; the second sweep occurred one hour before the bombs went off. People were able to come and go freely, and carry bags and items in and out of the area.
At 2:49 pm EDT (18:49 UTC), about two hours after the winner crossed the finish line, but with more than 5,700 runners yet to finish, two bombs detonated on Boylston Street near Copley Square about 210 yards (190 m) apart, just before the finish line. The first exploded outside Marathon Sports at 671–673 Boylston Street at 2:49:43 pm EDT. At the time of the first explosion, the race clock at the finish line showed 04:09:43. The second bomb exploded at 2:49:57 pm EDT, about 13 seconds later and one block farther west at 755 Boylston Street.
The blasts blew out windows on adjacent buildings but did not cause any structural damage. Some runners continued to cross the line until 2:57 pm EDT, 8 minutes after the explosions.
The Federal Bureau of Investigation led the investigation, assisted by the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Central Intelligence Agency, the National Counterterrorism Center, and the Drug Enforcement Administration, treating the bombings as a terrorist attack and naming two official suspects.
United States government officials stated that there had been no intelligence reports that indicated such a bombing would take place. Representative Peter 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."
Following the identification of the suspects, their father claimed that the FBI had been watching his family and questioned his sons in Cambridge, Massachusetts, five times in relation to possible explosions on the streets of Boston.

At the site of the explosion, investigators found shrapnel that included bits of metal, nails, and bearing balls, as well as black nylon pieces from a backpack. The lid of a pressure cooker was found on a nearby rooftop. Investigators also found the remains of an electronic circuit board and wiring. All evidence was sent to the FBI Laboratory for analysis. Both of the improvised explosive devices were pressure cooker bombs, manufactured by the bombers. Authorities reportedly confirmed that the brothers used bomb making instructions found in Al Qaeda in the Arabian Peninsula's Inspire magazine. After the suspects were identified, The Boston Globe reported that Tamerlan purchased fireworks from a fireworks store in New Hampshire.
On April 19, the FBI, West New York Police Department, and Hudson County Sheriff's Department seized computer equipment from the suspects' sister's apartment located in West New York, New Jersey.
On April 24, the FBI and the Department of Homeland Security released a joint intelligence bulletin which the Los Angeles Times reports to include the "preliminary analysis of recovered evidence, [for] each device". The report says investigators believe that the two homemade bombs used were triggered by long-range remote controls used for toy cars; and that investigators have finished a preliminary reconstruction of the bombs that were used during the April 15 attacks. Investigators believe that the brothers learned how to construct the bombs by consulting the radical Islamist online magazine Inspire.
In a news conference held at 5:20 pm on April 18, the FBI released photographs and surveillance videos showing two suspects—each carrying backpacks and walking nonchalantly but purposefully in single file formation—and sought the public's help in identifying them. The FBI released the photos, in part, to limit the damage by those wrongly targeted by incorrect news reports and social media speculations. Authorities later said that releasing the suspect's photos "was a turning point in the investigation, no doubt about it."
Jeff Bauman, a victim who lost both legs, was adjacent to the location of one of the bombs; upon recovering consciousness, he asked for pen and paper and wrote a note to the FBI, "bag, saw the guy, looked right at me". Bauman was later able to provide detailed descriptions to the authorities of a suspect who was seen placing a backpack beside him at the bombing scene two and a half minutes before it exploded, enabling the photo to be identified and circulated quickly.
The suspects, initially identified by the FBI as unnamed suspects 1 and 2 (or "black hat" and "white hat", respectively) from photographic and video evidence, had "acted differently" after the explosions; they had stayed to watch the aftermath and walked away "casually", rather than fleeing. Asked for assistance in identifying the suspects, the public provided a deluge of photographs and home movie records to police, which were scrutinized by both authorities and online public social networks.
Based on assistance from the public, the authorities identified the suspects as two brothers whose family had immigrated to the United States as refugees around 2002: 26-year-old Tamerlan Tsarnaev (Russian: Тамерлан Царнаев /ˌtæmərˈlɑːn ˌtsɑrˈnaɪ.ɛf/ ta-mər-lahn tsahr-ny-ef), born on October 21, 1986, and killed on April 19, 2013, and 19-year-old Dzhokhar Tsarnaev (Russian: Джохар Царнаев /ˌdʒoʊˈxɑr ˌtsɑrˈnaɪ.ɛf/ djoh-khar tsahr-ny-ef), born on July 22, 1993.[a]
