BOSTON—Lawyers for Boston Marathon bomber Dzhokhar Tsarnaev on Dec. 27 asked an appellate court to overturn his conviction and death penalty sentence for helping carry out the 2013 attack, which killed three people and wounded more than 260 others.
Lawyers for Tsarnaev, 25, argued in a brief filed with the 1st U.S. Circuit Court of Appeals in Boston that a lower-court judge’s refusal to move the case to another city not traumatized by the bombings deprived him of a fair trial.
