The Boston Marathon bombings were a terrorist attack during the Boston Marathon on April 15, 2013. Two bombs exploded, 13 seconds apart, at 2:49 p.m. EDT (18:49 UTC) on Boylston Street, near the finish line—killing three people and injuring 183 others.23 The Federal Bureau of Investigation (FBI) took over the investigation,4 coordinating the efforts of multiple agencies and expediting the “full resources [of the federal government] to investigate the bombings”.5
On April 18, the FBI asked the public for assistance both before and after releasing photographs and videos of two suspects.6 These were identified that day with help from the public as brothers Dzhokhar and Tamerlan Tsarnaev.
Shortly after the release of the photos, the suspects allegedly killed an MIT police officer, and carjacked an SUV forcing its driver to give the suspects money and withdraw cash from an ATM. Police were able to track the Tsarnaev brothers to Watertown, Massachusetts, where a shootout with explosions ensued around 1 a.m. on April 19. A MBTA officer was critically injured and Tamerlan Tsarnaev fatally injured, allegedly by his brother driving the car over him while trying to escape. Tamerlan Tsarnaev later died in hospital from injuries sustained.
Dzhokhar Tsarnaev was also injured but escaped and for a time eluded apprehension. An unprecedented manhunt ensued, with thousands7 of police and military personnel searching for Dzhokhar in a 20-block area of Watertown. On April 19, authorities requested all residents of Watertown and the surrounding areas, including the city of Boston, to stay indoors, and most public institutions and businesses as well as the public transportation system were shut down. By 7 p.m. that evening, a Watertown resident found the injured Dzhokhar hiding under a tarpaulin in a boat stored behind his house. Following a standoff, he was captured by police and taken to a hospital.Read more
