Convicted sniper John Allen Muhammad will die by lethal injection when he is executed next month.
Virginia Department of Corrections spokesman Larry Traylor says Muhammad declined to choose between lethal injection and electrocution, so under state law the method defaults to lethal injection.
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.
In all, 10 people were killed were in four states, including Alabama and Louisiana, before Muhammad and a co-defendant moved on to Virginia, Maryland and the District of Columbia for a rampage that terrified residents of the D.C. region. Six people also were wounded.
Muhammad's teenage co-defendant Lee Boyd Malvo is serving a life sentence.
