Boston Marathon Bomber's Life in Balance as Jury Deliberates

The jury in the Boston Marathon bombing trial on Friday heads into its third day of deliberations on whether Dzhokhar Tsarnaev is sentenced to death or to life in prison without the possibility of release.
Tsarnaev, a 21-year-old ethnic Chechen was convicted last month of killing three people and injuring 264 others by detonating a pair of homemade pressure-cooker bombs at the race's crowded finish line on April 15, 2013.
Three days later, he and his 26-year-old brother shot a police officer to death, setting off 24 hours of chaos in which the pair carjacked a Chinese businessman and hurled bombs at police, triggering a daylong lockdown of most of the Boston area while police searched for Tsarnaev.
Federal prosecutors contend that Tsarnaev, who moved with his family to Cambridge, Massachusetts, from Russia a decade before the attack, was an adherent of al Qaeda's militant Islamist ideology who wanted to "punish America" with the attack.
