The '''Boston Marathon bombing''', sometimes referred to as just simply the '''Boston bombing''',<ref>{{Cite news |date=2021-03-22 |title=Boston bombing: Tsarnaev's death sentence could be reinstated |url=https://www.bbc.com/news/world-us-canada-56482800 |access-date=2024-03-19}}</ref> was an [[Islamism|Islamist]] [[Domestic terrorism in the United States|domestic terrorist]] attack that took place during the annual [[Boston Marathon]] [[2013 Boston Marathon|on April 15, 2013]]. Brothers [[Tamerlan Tsarnaev|Tamerlan]] and [[Dzhokhar Tsarnaev]] planted two homemade [[pressure cooker bomb]]s that detonated near the finish line of the race 14 seconds and {{convert|210|yd|m}} apart. Three people were killed and hundreds injured, including 17 who lost their limbs.<ref name="NYDN-5/15" /><ref name="globe-number-injured" /><ref name="cnn-what-we-know" />

On April 18, 2013, the [[Federal Bureau of Investigation]] (FBI) released images of two suspects in the bombing.<ref name="Clark Estes" /><ref name="AutoLC-4" /><ref name="AutoLC-5" /> The two suspects were later identified as the Tsarnaev brothers. Later on the evening of April 18, the Tsarnaev brothers killed an [[Massachusetts Institute of Technology Police Department#Shooting by Boston Marathon bombing suspects|MIT policeman]] (Sean Collier) and proceeded to commit a carjacking. They engaged in a shootout with police in nearby [[Watertown, Massachusetts|Watertown]] during which two officers were severely injured (one of the injured officers, Dennis Simmonds, died a year later). Tamerlan was shot several times, and his brother Dzhokhar ran him over while escaping in the stolen car. Tamerlan died soon thereafter.

An unprecedented manhuntsearch for Dzhokhar Tsarnaev ensued, with thousands of law enforcement officers searching a 20-block area of Watertown.<ref name="AutoLC-6" /> Residents of Watertown and surrounding communities were asked to stay indoors, and the transportation system and most businesses and public places closed.<ref name="AutoLC-7" /><ref name="AutoZ2-1" /> After a Watertown resident discovered Dzhokhar hiding in a boat in his backyard,<ref>"Two unnamed officials say Dzhokhar Tsarnaev, 19, did not have a gun when he was captured Friday in a Watertown, Mass. backyard.

During questioning, Dzhokhar said that he and his brother were motivated by the wars in Iraq and Afghanistan, that they were self-[[Radicalization|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 the [[Inspire (magazine)|online magazine]] of [[al-Qaeda in the Arabian Peninsula]].<ref name="AutoLC-8" /> He also said they had intended to travel to New York City to bomb [[Times Square]].

A 20-block area of Watertown was [[Cordon and search|cordoned off]], and residents were told not to leave their homes or answer the door, as officers scoured the area in tactical gear.

The brothers' father spoke from his home in [[Makhachkala, Dagestan]], encouraging Dzhokhar to: "Give up. You have a bright future ahead of you. Come home to Russia."

On April 22, 2013, formal criminal charges were brought against Tsarnaev in the [[United States District Court for the District of Massachusetts]] during a bedside hearing while he was hospitalized. He was charged with use of a [[weapon of mass destruction]] and with malicious destruction of property resulting in death.<ref name="DOJ affidavit" /> Some of the charges carried potential sentences of [[life imprisonment]] or the [[Capital punishment in the United States|death penalty]].<ref name="USC2332" /> Tsarnaev was judged to be awake, mentally competent, and lucid, and he responded to most questions by nodding.

On April 15, several people who were near the scene of the blast were taken into custody and questioned about the bombing, including a Saudi man whom police stopped as he was walking away from the explosion; they detained him when some of his responses made them uncomfortable.<ref name="AutoLC-120" /><ref name="AutoLC-121" /><ref name="Hunter" /><ref name="AutoLC-122" /> Law enforcement searched his residence in a Boston suburb, and the man was found to have no connection to the attack.

On the night of April 18, two men who were riding in a taxi in the vicinity of the shootout were arrested and released shortly thereafterafter that when police determined that they were not involved in the Marathon attacks.<ref name="AutoLC-124" /> Another man was arrested several blocks from the site of the shootout and was forced to [[Strip search|strip naked]] by police who feared that he might have concealed explosives.

Dias Kadyrbayev, 19, and Azamat Tazhayakov, 20, were natives of [[Kazakhstan]] living in the U.S.<ref name="AutoLC-127" /><ref name="AutoQU-10" /> They were Dzhokhar Tsarnaev's roommates in an off-campus housing complex in [[New Bedford, Massachusetts]], where Tsarnaev had sometimes stayed.<ref name="businessinsider" />

Phillipos, Kadyrbayev, Tazhayakov, and Tsarnaev entered the [[University of Massachusetts Dartmouth]] in the fall of 2011 and knew each other well. After seeing photos of Tsarnaev on television, they traveled to his dorm room, where Kadyrbayev and Tazhayakov retrieved a backpack and laptop belonging to Tsarnaev, while Phillipos acted as a lookout. The backpack was discarded, but police recovered it and its contents in a nearby New Bedford landfill on April 26. During interviews, the men initially denied visiting the dorm room but later admitted their actions.<ref name="businessinsider" /><ref name="usatoday" />

==== Arrests and legal proceedings ====

Police arrested Kadyrbayev and Tazhayakov were arrested by police at the off-campus housing complex during the night of April 18–19. An unidentified girlfriend of one of the men was also arrested,<ref name="AutoLC-127" /><ref name="AutoQU-10" /> but all three were soon released.<ref name="businessinsider" />

Kadyrbayev and Tazhayakov were re-arrested in [[New Bedford]] on April 20 and held on immigration-related violations. They appeared before a federal [[immigration judge]] on May 1 and were charged with overstaying their [[student visa]]s.<ref name="AutoQU-11" /><ref name="AutoLC-129" /><ref name="AutoLC-130" /> That same day, they were charged criminally with:

A federal indictment was unsealed against Khairullozhon Matanov on May 30, 2014, charging him with "one count of destroying, altering, and falsifying records, documents, and tangible objects in a federal investigation, specifically information on his computer, and three counts of making materially false, fictitious, and fraudulent statements in a federal terrorism investigation". Matanov bought dinner for the two Tsarnaev brothers 40 minutes after the bombing. After the Tsarnaev brothers' photos were released to the public, Matanov viewed the photos on the CNN and FBI websites before attempting to reach Dzhokhar, and then tried to give away his cell phone and delete hundreds of documents from his computer. Prosecutors said that Matanov attempted to mislead investigators about the nature of his relationship with the brothers and to conceal that he shared their philosophy of violence.<ref>{{cite news|url=http://www.cnn.com/2014/05/30/justice/boston-marathon-bombings-charges/|title=Massachusetts man charged with obstructing Boston bombings probe|first1=Jason|last1=Hanna|first2=Mariano|last2=Castillo|date=May 30, 2014|work=CNN|access-date=April 8, 2015}}</ref><ref name="LySentenceJune">{{cite news|first=Laura|last=Ly|url=http://www.cnn.com/2015/06/18/us/tsarnaev-friend-sentence/|title=Friend of Boston marathon bombers gets 30-month sentence|work=CNN|date=June 18, 2015}}</ref>
