PORTLAND, Ore. -- A man suffered life-threatening injuries after he was shot in a car near Southeast 7th Avenue and Stark Street early Tuesday morning.

The victim was a passenger in the car, according to Portland police.

He and a friend were in a bar close to the shooting scene, police said. They left without incident and were driving down Stark when gunfire erupted about 2:30 a.m.
