Defense lawyers began making their case to spare the life of Boston Marathon bomber Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv) by contrasting him with his older brother, who they said was "consumed by jihad."

Attorney David Bruck told jurors Monday that Tsarnaev was "a good kid" who was led down the path to terrorism by his brother, Tamerlan, who was later killed in a shootout with police.

The jury convicted Tsarnaev earlier this month in the 2013 bombing that killed three spectators and wounded more than 260 others. He also was found guilty of killing an MIT police officer as the brothers tried to flee.

The jury must decide whether Tsarnaev deserves the death penalty, as prosecutors have called for, or if he should spend the rest of his life in prison.
