Anchorage police say a man's ex-roommate shot him twice when an argument outside on Eureka Street, just north of Fireweed Lane, turned violent about 6 p.m. Tuesday.

The victim, a man in his early 20s whom police have not identified, was hit in the stomach and arm, according to police Sgt. Michael Kerle. Both men got back in their vehicles, Kerle said. The victim drove a short distance before getting out, stumbling down the street and collapsing on his back, the sergeant said.

The shooter sped off in a white late-'90s Chevrolet Blazer with dark tinted windows, Kerle said. He remained at large Tuesday night.

Officers spoke to the wounded man before an ambulance rushed him to a hospital, where he was in surgery, Kerle said.

"We were able to do an interview with him. He was conscious," Kerle said. "But by the time he left here, he had lost consciousness."

Kerle said officers had a first name of the shooter, but the police sergeant declined to give out any description of the man. He is still believed to be armed.

Crime scene investigators were analyzing the area of the shooting and where the victim fell late Tuesday.
