BOSTON—A federal appeals court on Thursday ordered the judge who oversaw Boston Marathon bomber Dzhokhar Tsarnaev’s trial to investigate the defense’s claims of juror bias and determine whether his death sentence should stand.
A three-judge panel of the Boston-based 1st U.S. Circuit Court of Appeals did not throw out Mr. Tsarnaev’s death sentence. Defense lawyers had pushed for that while claiming bias by two people who sat on the jury that convicted him for his role in the bombing that killed three people and injured hundreds near the marathon’s finish line in 2013.
