2003–2007 According to Tsarnaev's immigration file, he received his visa at the U.S. consulate in
Ankara, Turkey and was admitted to the United States in 2003. After arriving in the U.S., he attended
Cambridge Rindge and Latin School, a public high school. He applied for admission at the
University of Massachusetts Boston for the fall of 2006, but was rejected. He attended
Bunker Hill Community College part-time for three terms between 2006 and 2008, studying accounting with hopes of becoming an engineer. He dropped out of school to concentrate on boxing.
2008 In 2008, Tsarnaev's mother urged him to embrace Islam because she was concerned about his drinking, smoking, and pursuit of women. She said he began to read more about it on the Internet. the mosque has condemned terrorism and would later ask Tsarnaev to stop attending because he interrupted the Friday sermon. The case was dismissed for lack of prosecution. Tsarnaev dated Katherine Russell of
North Kingstown,
Rhode Island on and off while she attended
Suffolk University from 2007 to 2010. The Tsarnaev brothers' uncle, Ruslan Tsarni, said he "had been concerned about his nephew being an extremist since 2009". Tsarni said that Tsarnaev's radicalization started not during his visit to Russia in January 2012, but much earlier in Boston after he was influenced by a Muslim convert known as "Misha". "Misha" was later identified as Mikhail Allakhverdov, a 39-year-old from
Rhode Island (of
Armenian-
Ukrainian origin, born in
Azerbaijan). Allakhverdov told
The New York Review of Books that he rejected violence, was not Tsarnaev's teacher, had not spoken to Tamerlan in three years and had never met his family members. Furthermore, he said that he had cooperated with a brief
FBI investigation that the
NYRB reported had found no ties between Allakhverdov and the attacks. while remarking that he "didn't understand" Americans and did not have any American friends. He added that he abstained from drinking and smoking, because "God says no to alcohol" and that "there are no values anymore. People can't control themselves". Rule changes disqualified all non-US citizens from Golden Gloves boxing, ending Tsarnaev's boxing career and Olympic hopes. In the spring of 2010, Katherine Russell became pregnant with Tsarnaev's child. Russell dropped out of college at the end of her junior year and married Tsarnaev on June 21, 2010, in a 15-minute ceremony in an office at the Masjid Al Quran in the
Dorchester area of Greater Boston. The couple's daughter was born in October 2010. Tsarnaev first came to the attention of Russian security forces in December 2010 when
William Plotnikov was briefly detained in Dagestan and forced to disclose his social networking contacts in North America with ties to Russia.
2011 In early 2011, Russia's
Federal Security Service (FSB) told the
Federal Bureau of Investigation that Tsarnaev was a follower of Islamic extremism. The FSB said that he was preparing to leave the United States to travel to the Russian region to join unspecified underground groups. The FBI initially denied that it had contacted Tsarnaev, but then confirmed that it had after Tsarnaev's mother talked about the FBI's contacts with her son on
RT. The FBI said that it interviewed him and relatives of his, but did not find any terrorist activity. Tsarnaev's mother said that FBI agents had told her they feared her son was an "extremist leader", and that he was getting information from "extremist sites". She said Tsarnaev had been under FBI surveillance for at least three years and that "they were controlling every step of him". The FBI denied this accusation. Tsarnaev "vaguely discussed"
jihad during a 2011 phone call with his mother that was taped by the FSB, and intelligence officials also discovered text messages in which his mother discussed how he was ready to die for Islam. In late 2011, the
Central Intelligence Agency put both Tsarnaev and his mother on its
Terrorist Identities Datamart Environment database.
Alleged involvement in Waltham triple murder Two Jewish men, Erik Weissman and Raphael Teken, as well as their roommate Brendan Mess, were killed in a triple homicide in
Waltham, Massachusetts on September 11, 2011. It was reported on April 23, 2013 that local authorities believed Tsarnaev may have been responsible for the triple homicide, and that they and the FBI were investigating the possibility. A search warrant affidavit that was partially unsealed in November 2019 provided further details about Tsarnaev's alleged connection to the crime.
2012 Visit to Russia Tsarnaev traveled to Russia through Moscow's
Domodedovo International Airport in January 2012, and returned to the U.S. in July 2012.
U.S. House Homeland Security Chairman
Michael McCaul said he believed that Tsarnaev received training during his trip and became radicalized. In an early report, Dagestan's interior minister Abdurashid Magomedov said through a spokesman that Tsarnaev "did not have contact with the [Islamist] underground during his visit". Tsarnaev's maternal third cousin, Magomed Kartashov, is a figure in Dagestan's Islamist community. Zubeidat Tsarnaeva confirmed that they "became very close." Kartashov's Islamist organization, "The Union of the Just," advocates Islam as a political system under
sharia law. Kartashov later stated the Boston bombing was "good" in that it would increase converts to Islam similarly to the attacks of September 11. According to media reports, Tsarnaev was seen by Dagestan police, who were conducting surveillance, making six visits to a known Islamic militant in a
Salafi mosque in Makhachkala founded by an associate of
Ayman Zawahiri. According to Russian investigative newspaper
Novaya Gazeta, quoting unnamed Russian security sources, Tsarnaev was linked to 23-year-old
William Plotnikov, an ethnic Russian-
Tatar Islamic militant and Canadian citizen, with whom he communicated via online social networking sites. Once in Dagestan, Tsarnaev is said to have met on several occasions with Makhmud Mansur Nidal, a 19-year-old Dagestani-Palestinian man. Nidal was under close surveillance by Dagestan's anti-extremism unit for six months as a suspected recruiter for Islamist insurgents before the police killed him. In an interview, Tsarnaev's father later said he had to force his son to return to the United States to complete his U.S. citizenship application after Tsarnaev tried to convince his family to allow him to stay in Dagestan for good.
Return to U.S. Tsarnaev returned to the U.S. on July 17, 2012, having grown a long, thick beard and wearing kohl around his eyes as a sign of his religious devotion to
Sunni Islam and the prophet
Muhammad. His life took on an "increasingly puritanical religious tone" with "Islamist certainty". After his return to the U.S., Tsarnaev created a YouTube channel with playlist links to two videos which were tagged under a category labeled "Terrorists", including one to Dagestani Islamic militant Amir Abu Dujana (Gadzhimurad Dolgatov, also known as 'Robin Hood', a commander of a small group in the
Kizilyurt district, who was killed in battle in late December 2012); the videos were later deleted.
CNN and the
SITE Institute found a screen grab of one of the videos, which featured members of the militant Islamist group
Caucasus Emirate from the North Caucasus. He frequently read extremist sites, including
Al-Qaeda in the Arabian Peninsula's
Inspire online magazine. Tsarnaev was pulled over by police in Boston,
Brookline, and Cambridge at least nine times in four years. In November 2012, Tsarnaev reportedly confronted a shopkeeper at a Middle Eastern grocery store in Cambridge near a mosque where he sometimes prayed after seeing a sign there advertising Thanksgiving turkeys. He said "This is
kuffar"—an Arabic reference to non-Muslims—"that's not right!" Also in November 2012, Tsarnaev stood up and challenged a sermon in which the speaker said that, just like "we all celebrate the birthday of the Prophet, we can also celebrate July 4 and Thanksgiving," according to Yusufi Vali, a mosque spokesman. On February 6, 2013, Tsarnaev reportedly purchased 48 mortars containing explosive powder at a store in Seabrook, New Hampshire. On April 14, 2013, the day before the bombings, Tsarnaev reportedly received electronic
IED components that were sent to him by mail; he had ordered the components online. ==2013 Boston Marathon bombing and aftermath==
