UPDATE May 13, 2013, 9:44 p.m. Carjacking suspect John Comeau has been apprehended in Warren County, Va.
EARLIER: WASHINGTON - Fauquier County police are looking for a carjacking suspect who stole a car from a 74-year-old driver Monday.
The Fauquier County Sheriff's Department says John Comeau, 22, approached the victim at a grocery store in Marshall, Va., and asked for a ride.
The victim drove to another location in northern Fauquier County when Comeau said he needed the car. He then opened the driver's side door and pushed the driver out of the car and drove away with the driver's dog in the back seat, according to the sheriff's department.
The victim suffered a minor ankle injury. The dog was later found in Upperville, Va., just inside the Loudoun County line, the sheriff's department says.
Investigators believe Comeau was traveling to Winchester, Va., or to Pottsville, Pa. He has ties to both communities and used the victim's credit card in Winchester.
Comeau is driving a 2006, grey Honda CRV with Virginia license plates MOJOKT.
An arrest warrant for carjacking and credit card theft charges has already been filed against Comeau.
Police ask anyone who has seen Comeau to call Detective Cory Ashby at 540-422-8713 or send an email to firstname.lastname@example.org.
