Lawyers for the surviving Boston Marathon bombing suspect are asking a federal judge to delay his trial until September.
Dzhokhar Tsarnaev is scheduled to go on trial Jan. 5 on multiple charges. He could face the death penalty if convicted.
In a motion filed on Tuesday, Tsarnaev's lawyers argue that the trial, as currently scheduled, would begin faster than 99 of the 119 federal capital trials held since 2004.
Three people died and more than 260 were injured when two bombs went off at the finish line of the marathon on April 15, 2013.
Tsarnaev was indicted 18 months ago. His lawyers say a September 2015 trial would be more realistic given the "extraordinary complexity and international dimensions" of the case.
Tsarnaev's brother, Tamerlan, died in a shootout with police.
