Two Vancouver men were injured early Saturday when their vehicle came under fire from another motorist on eastbound state Highway 500 near Thurston Way, according to the Washington State Patrol.

About 10 rounds were fired at a 1997 Honda Civic coupe in the 2:02 a.m. incident, said WSP Trooper Will Finn. The driver, a 29-year-old man, was shot in the knee and a 32-year-old man in the front passenger seat had a grazing bullet wound to the back of his head.

The injuries did not appear to be life threatening, Finn said.

Both men were transported to PeaceHealth Southwest Medical Center for treatment, Finn said.

The incident occurred just after 2 a.m. as the Honda was heading east on the highway. The driver told investigators that an unknown type vehicle began following closely and moved to the left lane to pass before a passenger in the other vehicle fired what is believed to be a 9 mm handgun at the driver’s side of the Honda, according to Finn. He said at least eight bullets were found in the car.
