Jury Reach Verdict on Boston Marathon Bomber Dzhokhar Tsarnaev
A US jury has unanimously sentenced Boston bomber Dzhokhar Tsarnaev to death for perpetrating one of the bloodiest assaults in America since the September 11, 2001 attacks.
It took the jury more than 14 hours to choose death on six of the 17 capital counts over life imprisonment for the 21-year-old Muslim former university student of Chechen descent who came to the United States as a child.
The same 12-member panel convicted him on April 8 on all 30 counts relating to the April 15, 2013 bombings, the murder of a police officer, a car jacking and a shoot-out while on the run.
Three people were killed and 264 others wounded, including 17 who lost limbs, in the twin blasts near the finish line at the northeastern city's popular marathon.
Tsarnaev went on the run and was arrested four days later, hiding and injured in a grounded boat on which he had scrawled a bloody message apparently defending the attacks as a means to avenge the US wars in Iraq and Afghanistan.
Two years later, he stood in a dark blazer with his hands clasped before him, showing no emotion as the court clerk read from the death penalty.
The court was silent during the verdict reading.
Government prosecutors called Tsarnaev a remorseless terrorist who deserves to die for inflicting carnage. The defence said he was a "lost kid," manipulated into the "heinous crime" by his radical older brother.
Prominent survivors had opposed the death penalty for Tsarnaev, a teenager at the time, fearing that lengthy appeals would dredge up their agony.
The federal sentence comes despite widespread opposition to the death penalty in the state of Massachusetts, where no one has been executed since 1947.
Survivors, including the parents of the youngest victim eight-year-old Martin Richard, crammed into the gallery to hear the verdict.
The decision caps a harrowing, more than two-month trial that saw the court relive the horror of the attacks day after day through grisly videos and heartbreaking testimony from those who lost limbs and loved ones.
The attacks shocked the relatively small northeastern city of Boston and revived fears of terrorism in the United States after the September 11, 2001 strikes on New York, Washington and Pennsylvania.
Tsarnaev's lawyers admitted his guilt but said he was manipulated into taking part by his more radical elder brother, 26-year-old Tamerlan who was shot dead by police on the run.
They deployed dozens of witnesses during a three-week sentencing phase in an attempt to save him from the death penalty.
"Jahar would never have done this but for Tamerlan. The tragedy would never have occurred but for Tamerlan," said lawyer Judy Clarke.
She appealed on the jury to consider Tsarnaev's young age, his brother's domineering influence, his parents' return to Russia in 2012, the affection of his friends and teachers, and his apparent remorse.
But government prosecutors said Tsarnaev is a callous terrorist living a double life as a pot-smoker enrolled at University of Massachusetts, Dartmouth.
They say he self-radicalised as early as high school and was captivated by the teachings of US-Yemen cleric Anwar al-Awlaki, who was killed in a drone strike in 2011, and pointed to his note justifying the attacks.
"No remorse, no apology. Those are the words of a terrorist convinced he has done the right thing," US assistant lawyer Steven Mellin said.
