UPDATE, 11:40AM: There are multiple, unconfirmed reports that the suspect shot himself on U.S. 66 near Front Royal.
11:20AM: New alert for suspect vehicle is being shared with officers. It's possible that the suspect switched cars north of Staunton. We've seen an unmarked police car speed north on U.S. 11 from Mount Crawford at 11:15, with lights on, so there may be some northern movement of this manhunt.
