Tamerlan Tsarnaev

Tamerlan Anzorovich Tsarnaev (/ˌtæmərˈlɑːn ˌtsɑːrˈnaɪɛf/; October 21, 1986 – April 19, 2013) was a Russian-born terrorist of Chechen and Avar descent who, with his younger brother Dzhokhar Tsarnaev, planted pressure cooker bombs at the Boston Marathon on April 15, 2013. The bombings killed three people and reportedly injured as many as 281 others. He emigrated to the United States in 2004 at the age of 18. At the time of the bombings, Tsarnaev was an aspiring boxer.

Shortly after the Federal Bureau of Investigation declared them suspects in the bombings and released images of them, the Tsarnaev brothers killed an MIT policeman, carjacked an SUV, and engaged in a shootout with the police in the Boston suburb of Watertown. According to the federal indictment, during the shootout, Tamerlan was captured but died, partly as a result of his brother driving over him. A MBTA police officer was critically injured by friendly fire in the course of Dzhokhar's escape in the SUV. An injured Dzhokhar escaped, but was found, arrested, and hospitalized on the evening of April 19 after an unprecedented manhunt in which thousands of police officials searched a 20-block area of Watertown.

During his incarceration, Tsarnaev's brother allegedly said during questioning that the pair next intended to detonate explosives in Times Square in New York City. Dzhokhar reportedly told authorities that he and his brother were radicalized, at least in part, by watching lectures by Anwar al-Awlaki.
