Boston Marathon bombing – a look back

Yahoo News

Dzhokhar and Tamerlan Tsarnaev, brothers of Central Asian origin, planted two pressure-cooker bombs along the route of the Boston Marathon in April 2013, killing three people and wounding 260.

Tamerlan Tsarnaev, 26, died days later after a gun battle with police. Dzokhar, then 19, was shot, wounded and captured.

At his murder trial, defense lawyers argued that Dzhokar had acted under the sway of his older brother, a former boxer who had embraced radical Islam and masterminded the attack. A jury nonetheless convicted him of the bombings last year. He has been sentenced to death. (AP)
