Boston Marathon Bombing

The 2013 marathon bombing killed three people and left 264 others wounded. In April, the same jury convicted Tsarnaev of all 30 counts brought against him.

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.

A moment of silence will be observed at 2:49 p.m. ET, the time when the first of two devastating bombs went off in the crowds gathered to watch the marathon in 2013.

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.
