The lawyers of the alleged Boston Marathon bomber asked to delay his trial Friday until September of 2015 at the very least, according to CBS.

"We recognize that the government and many members of the public, especially in the Boston area, may want the trial to begin quickly," Dzhokhar Tsarnaev's lawyers said in a court filing, "but it is critically important that any trial be fair, which means giving both sides, not just the government, enough time to uncover and present all relevant evidence," Boston.com reported.

21-year-old Tsarnaev is one of two alleged bombers that killed three people and wounded more than 260, including 16 who lost limbs, in the April 2013 Boston Marathon bombing. His brother and accomplice, Tamerlan, was killed during the police hunt for the duo.

Tsarnaev has pleaded not guilty. If convicted, he could face the death penalty.

According to Tsarnaev's lawyers, the November 3 trial doesn't even give them half of the preparation time allotted for other defendants who face a federal death sentence, CBS reported.

The lawyers are claiming the prosecutors have been disorganized and slow in producing a "massive amount" of evidence, which the lawyers need time to evaluate. The lawyers also need time to "explore mitigating factors that could lessen [Tsarnaev's] sentence if convicted," CBS reported.

The delay for a trial request comes in the same week Tsarnaev's sister Aliana, from New Jersey, was arrested for telling a woman she has "people who can go up there and put a bomb on you."

It is unclear when the judge will make a decision on the motion.
