Boston Bombing Suspect Wants Additional Lawyer

The defense team for the surviving Boston Marathon bombing suspect has made another attempt to add a national death penalty expert to its roster.

In papers filed in federal court Monday, lawyers for Dzhokhar Tsarnaev sought to add David Bruck to the defense team.

Tsarnaev's court-appointed lawyers asked in April that Bruck be added to the team, but the motion was denied.

His lawyer said in the new motion that the 19-year-old Tsarnaev now faces 17 charges which carry the death penlty, while in April he faced just two.

Prosecutors have not said yet whether they will seek the death penalty.

Tsarnaev has pleaded not guilty to 30 charges in connection with the April 15 bombings at the marathon finish line that killed three and injured more than 260.
