Birthday Party Shooting

PORTLAND, Ore. (AP) — Portland police say 2 young people were shot outside a birthday party.

Authorities said Saturday that a 16-year-old boy received traumatic injuries and was listed in critical condition. A 23-year-old man sustained non-life-threatening injuries.

Police say uninvited people showed up and were denied entry to the birthday party. They stayed in the area, and eventually a disturbance broke out just after midnight.

Authorities are searching for two or three people who fled after the shooting.

A 20-year-old friend of the teenage victim was arrested on a charge of unlawful possession of a firearm after police found two handguns in his vehicle. Authorities do not believe he was one of the people who injured the victims.
