Closing arguments begin in Boston Marathon bombing trial
Prosecutors and lawyers for Boston Marathon bomber Dzhokhar Tsarnaev have one last chance to make their case to the jury.
Closing arguments are scheduled for today in the first phase of Tsarnaev's death penalty trial.
Tsarnaev's lawyers have admitted he participated in the bombings but said his older brother was the mastermind behind the 2013 attack.
During its closing argument, the defence is expected to continue to focus on Tamerlan Tsarnaev's role.
Prosecutors are expected to remind the jury of the brutality of the attack, the three people who were killed and the others who were maimed.
If Dzhokhar Tsarnaev is convicted, the same jury will hear more evidence during a second phase of the trial to decide whether he receives the death penalty or life in prison.
