After more than 14 hours of deliberation, a jury sentenced Boston Marathon bomber Dzhokhar Tsarnaev to death by lethal injection on Friday. The jury declared that Tsarnaev had “intentionally killed” the 2013 marathon victims and found him guilty of an act of terrorism on all applicable counts. Only three jurors, however, believed that Tsarnaev was “susceptible” to the influence of his older brother, Tamerlan. On April 8, Tsarnaev was convicted of all 30 counts against him — 17 of which carry the death penalty — in relation to the bombing, which killed three and injured hundreds in April 2013. Tsarnaev can still appeal the verdict.
