Tamerlan Tsarnaev

Tamerlan Anzorovich Tsarnaev (October 21, 1986 – April 19, 2013) was a terrorist of Chechen and Avar descent. He and his younger brother, Dzhokhar Tsarnaev, committed the Boston Marathon bombing on April 15, 2013.

Tamerlan Tsarnaev entered the United States in the early 2000s and later became a lawful permanent resident. He attended Bunker Hill Community College and pursued a boxing career. At some point in time, he became an adherent of Islamic extremism. In 2011, Russia's Federal Security Service (FSB) warned the Federal Bureau of Investigation (FBI) about Tsarnaev's extremism and his alleged connection to underground groups in the Russian region. Later in 2011, the Central Intelligence Agency (CIA) added Tsarnaev to its Terrorist Identities Datamart Environment database.
