Several of convicted Boston Marathon bomber Dzhokhar Tsarnaev's relatives appeared in Boston federal court on May 4 to testify at the second phase of his trial, where a jury will determine whether he is sentenced to death for killing three people and wounding more than 260 in the 2013 bombing attack.
A family member told the court that Dzhokhar's brother, Tamerlan, had described feeling a "rage of hatred" during a visit to Russia in 2012.
Naida Suleimanova, a cousin of the brothers, said she was scared when she learned Tamerlan had adopted extremist views.
The jury must decide if Tsarnaev, 21, should be executed or given life imprisonment for his role in the bombings.
Defense attorneys have been trying to paint Tsarnaev as a secondary player in an attack conceived and led by Tamerlan, who died after a gunfight with police four days after the April 15, 2013, bombing.
Tsarnaev is a naturalized U.S. citizen. He and his brother had roots in Russia's North Caucasus region and spent part of their childhood in Kyrgyzstan.
