WASHINGTON ( CNN ) -- Virginia prosecutors are asking a state court to set a November 9 execution date for John Allen Muhammad , convicted in a series of sniper-style shootings that terrorized the Washington area in 2002 . John Allen Muhammad was sentenced to death for the slaying of Dean Harold Meyers . In a letter dated Wednesday , Senior Assistant Attorney General Katherine B. Burnett said the November date `` has been carefully coordinated with the governor 's office to insure his availability for any clemency petition Muhammad may wish to pursue . '' Burnett enclosed a copy of a proposed execution order `` for the court 's convenience . '' Muhammad 's attorney said he will file an appeal with the U.S. Supreme Court , and will ask the governor for clemency . During a three-week period in October 2002 , police say , Muhammad and his young protege , Lee Boyd Malvo , shot 13 people , killing 10 . The two also are suspected in other shootings and murders in Tacoma , Washington , Montgomery , Alabama , and the Washington , D.C. , area . Muhammad , now 48 , was convicted of murder in the death of Dean Harold Meyers at a Manassas , Virginia , filling station . Meyers was killed by a single bullet , which became the signature of the two-person sniper team . Ultimately , Muhammad was convicted of the Meyers ' killing and of one Maryland murder , which prosecutors there said was `` insurance '' in case the Virginia conviction was overturned . Malvo was convicted of one Virginia shooting and was sentenced to life imprisonment . Muhammad 's attorney , Jon Sheldon , released the prosecutor 's letter Friday . The letter , addressed to the chief judge of the Prince William County Circuit Court , says the court must hold a hearing within 10 days of receiving the letter , and must set an execution date no later than 60 days after the hearing . Since Muhammad is not required to be at the hearing , Burnett asks that the court conduct the hearing by means of a conference call .
Justice was proposed for the convicted sniper John Allen Muhammad . Police acquitted Muhammad , Lee Boyd Malvo shot 13 people , killing 10 . Muhammad 's lawyer says he will seek clemency .
