RICHMOND, Va. (AP) - The mastermind of the 2002 Washington, D.C.-area sniper attacks will die by lethal injection this month, Virginia officials said Tuesday.

John Allen Muhammad declined to choose between lethal injection and electrocution, so under state law the method defaults to lethal injection, Virginia Department of Corrections spokesman Larry Traylor said.

Muhammad is scheduled to be executed Nov. 10 for the October 2002 slaying of Dean Harold Meyers at a Manassas gas station during a string of shootings.

The three-week killing spree in October 2002 left 10 dead in Maryland, Virginia and the District of Columbia.

Muhammad and his teenage accomplice, Lee Boyd Malvo, were also suspected of shootings in several other states, including a killing in Louisiana and another in Alabama. Malvo is serving a life sentence in prison.

Muhammad's lawyers have asked the Virginia governor for clemency and plan to file an appeal with the U.S. Supreme Court.9
