PORTLAND, Ore. (AP) — Police are searching for a man who stabbed two people during broad daylight in northeast Portland.

Sgt. Chris Burley says officers who responded Friday morning found a man with a life-threatening injuries and a woman with less-severe injuries. A witness applied a tourniquet to the man before police arrived, and and both victims were taken to the hospital by ambulance.

Investigators believe the man and woman knew their attacker — a skinny man in his 20s or 30s. Officers canvassing the neighborhood failed to make an arrest, but found the likely weapon.
