WASHINGTON (AP) -- Virginia Attorney General Bill Mims on Wednesday filed a brief with the U.S. Supreme Court opposing a stay of execution for John Allen Muhammad, WVEC.com has learned.

Muhammad was mastermind of the 2002 sniper attacks in the Washington, D.C., area that left 10 dead.

His attorneys on Tuesday asked the high court to stop the scheduled November 10 execution.

Muhammad, 48, is scheduled to die by injection at Greensville Correctional Center.

In court papers, his attorneys said the execution should be put off while the court considers whether his trial lawyer was ineffective.

Muhammad was convicted of killing Dean Harold Meyers at a Manassas gas station during a three-week spree in October 2002 that spanned Maryland, Virginia and the District of Columbia.

His trial was held in Va. Beach because of pre-trial publicity.
