The jury will decide whether 21-year-old Dzhokhar Tsarnaev should be sentenced to death or life in prison. They are expected to begin deliberations today.
The twin bombings in 2013, carried out by Dzhokhar Tsarnaev with his older brother, Tamerlan, killed three people and left 264 others wounded. Seventeen of the counts can carry the death penalty.
Dzhokhar Tsarnaev's conviction is almost certain — given his lawyer acknowledged he participated in the deadly 2013 attack. If he is convicted, the jury will decide if Tsarnaev should be executed.
The prosecutor said the attack was a "cold, calculated terrorist act" carried out by Dzhokhar Tsarnaev. His defense argued there would have been no bombing without Tsarnaev's older brother.
The defense rested its case Tuesday in the trial of admitted Boston Marathon bomber Dzhokhar Tsarnaev. Because of holidays and judicial housekeeping duties, the trial won't resume until next week.
On the second day of Dzhokar Tsarnaev's trial, an amputee wept as she recalled seeing her foot just barely dangling from her leg. Tsarnaev could face the death penalty if convicted in the 2013 attack.
