On Friday, a federal appeals court vacated the death sentence for Boston Marathon convicted bomber Dzhokhar Tsarnaev, saying the judge who oversaw the case did not screen jurors adequately for potential biases. The case had rocked the city of Boston.

A three-judge panel of the 1st U.S. Circuit Court of Appeals ordered a new penalty-phase trial on whether the 27-year-old Tsarnaev should be executed.

The judges left intact the most serious death sentence-eligible convictions but ordered a new trial for the penalty phase to determine whether Tsarnaev receives another death penalty sentence or receives life in prison. 

“Just to be crystal clear,” the court said, “because we are affirming the convictions… and the many life sentences imposed on those remaining counts (which Dzhokhar has not challenged), Dzhokhar will remain confined to prison for the rest of his life, with the only question remaining being [sic] whether the government will end his life by executing him.”

A spokesperson for the U.S. Attorney’s office in Boston said they were reviewing the opinion and had no immediate comment.

“I’m not surprised,” said Ed Davis, who was the Boston Police Commissioner at the time of the bombings, regarding the ruling. “I am concerned though that the victims have to relive this incident by this ruling.” The new trial will open up the still painful wounds for those who died and the hundreds of those wounded and maimed.

Boston Mayor Marty Walsh agreed with the concerns of Davis. “I think the concern that some families have had from the very beginning was that this day was going to come, where they would have to relive another trial, and you know they shouldn’t have to relive another trial,” Walsh said. “The only thing that I’ll say is a positive… this guy will never see the light of day again. He’s going to live within those four walls. He got exactly what he deserved.”

Tsarnaev’s lawyers had said, prior to Dzhokhar’s sentencing, that he and his older brother, Tamerlan Tsarnaev, were responsible for setting off the two bombs at the marathon’s finish line. But they argued that Dzhokhar was less culpable than his brother, who they said was the mastermind behind the attack.
