Lawyers for John Allen Muhammad, the sniper behind a 2002 killing spree in the Washington, D.C., area will file an appeal Tuesday with the U.S. Supreme Court to try to stop his scheduled execution next week.

They had asked Virginia Gov. Timothy M. Kaine for clemency last month.

Muhammad, 48, is sentenced to die by lethal injection Nov. 10 at a Virginia prison. He is to be executed for the murder of Dean Harold Meyers at a Virginia gas station during a three-week killing spree in October 2002 that left 10 dead in Maryland, Virginia and the District of Columbia.

Muhammad and his teenage accomplice, Lee Boyd Malvo, were also suspected of fatal shootings in other states, including Louisiana and Alabama.

Malvo is serving a life sentence in prison.
