A federal judge has granted a request from Boston Marathon bombing suspect Dzhokhar Tsarnaev lawyers giving them more time to prepare challenges to evidence they expect to be brought against him.

U.S. District Court Judge George A. O'Toole Jr on Wednesday granted the extension from April 23 to May 7.

The defense said it needs more time to decide what evidence they will seek to suppress, or prevent prosecutors from presenting, at the trial, where Tsarnaev faces the possibility of the death penalty.

The 20-year-old Tsarnaev faces 30 federal counts in connection with the April 15 bombings, which killed three and injured more than 260.

He has pleaded not guilty to all charges and is being held without bail.  {Associated Press)
