A federal jury has found Dzhokhar Tsarnaev guilty of carrying out the 2013 Boston Marathon bombing.
The 12-person jury took a day and half to reach their verdict but on April 8 unanimously convicted Tsarnaev of the attack that killed three people and wounded more than 260 others.
The jury convicted Tsarnaev of all 30 counts he faced, 17 of them punishable by death.
At the next phase of the trial, the jury will decide if the 21-year-old Muslim immigrant of Chechen descent should receive the death penalty or life imprisonment.
Tsarnaev kept his hands folded and stared at the defense table as the guilty verdicts were read.
His lawyers had admitted Tsarnaev's guilt at the start of the trial but said Tsarnaev was influenced by his older brother Tamerlan to participate in planting the two shrapnel-packed homemade explosive devices near the finish line of the annual Boston Marathon in 2013.
Tamerlan had learned how to make the explosives from information downloaded from the Internet.
Tamerlan Tsarnaev was killed in a shoot-out with police.
Dzhokhar was found wounded, hiding in a boat, four days after the bombing as police put Boston and surrounding areas under lockdown while the manhunt progressed.
Police found writing scrawled inside the boat where Tsarnaev was hiding that said he and his older brother had carried out the attack as revenge for Muslims killed in conflicts where U.S. troops were fighting.
During the trial, the government called 92 witnesses. Survivors recounted the grim details of the minutes after the explosions.
The father of 8-year-old Martin Richard, who was one the three people killed in the blasts, testified how he had to leave his mortally wounded son so he could get help for their 6-year-old daughter, whose leg had been blown off.
