In a formal filing in court late Friday, the judge in the trial of Boston Marathon bombing suspect Dzhokhar Tsarnaev declined to dismiss charges because of alleged jury pool bias.
The defense was seeking for a second time to dismiss charges because of what they say are fundamental flaws with the way jury pools are created in federal trials in Boston.
The ruling was not unexpected. The trial is scheduled to continue Monday at 9 a.m.
Three people died and more than 260 others were injured when twin bombs exploded at the finish line of the 2013 Boston Marathon.
An MIT police officer was killed in an ambush a few days later.
Tsarnaev faces 30 charges, including using a weapon of mass destruction. He faces the death penalty, if convicted.
