NPR reports a jury in Boston has found 21-year-old Dzhokhar Tsarnaev guilty on multiple counts related to the 2013 bombings of the Boston Marathon. The twin bombings, carried out with his older brother, Tamerlan, killed three people and left 264 others wounded. The jury is still reading its verdict, but the counts that they have read so far are punishable by the death penalty. The jury will now weigh Tsarnaev's sentence. During the trial, prosecutors argued that Tsarnaev was cold and calculating. Tsarnaev's defense attorneys never denied that Tsarnaev participated in the bombings, but they argued that he was under the strong influence of his brother.
