Police say an unloaded shotgun was found in the vehicle. They're declining to release the soldier's identity because he hasn't been charged with a crime.
Maj. Chad Carroll is a spokesman for the First Calvary Division headquarters at Fort Hood. He said Dallas police were contacted about an AWOL soldier, but he said he was unaware of any threats. He says the matter remains under investigation by Army personnel.
Fort Hood is located near Killeen, about 160 miles southwest of Dallas. Maj. Nidal Malik Hasan is charged with killing 13 people at the Army post last month.
