A serious accident at a Southeast Portland residential intersection has claimed two lives and prompted a search for three passengers who fled the scene.

Witnesses say a Cadillac Escalade SUV sped through a stop sign at the intersection of

and plowed into a white Toyota Corolla. An emergency dispatcher said the first 911 call about the accident came in just before 5 p.m.

Both occupants of the Toyota were declared dead at the scene, Portland Police Bureau said in a press release. A passenger of the SUV was transported to a hospital. His condition was not known.

Witnesses said the SUV was going an estimated 60 MPH north on 28th, a residential street, when the accident happened. The impact sent the Toyota into a nearby utility pole. The SUV continued an estimated 100 feet and came to rest in the front yard of a home on 28th.

Police quickly began searching the neighborhood for three people seen fleeing the SUV. One suspect was described as having a limp.

One of the suspects was later apprehended, but the other two remained at large Saturday evening, police spokesman Sgt. Pete Simpson said. No description of the suspects was available, he said. "I don’t think they’re searching for the two right now," Simpson said shortly before 7 p.m.

The accident occurred near two bars with outside seating and traumatized many witnesses. Police were treating the accident as a crime scene.

They closed Southeast Gladstone Street from 28th to 29th Avenue and Southeast 28th Place in both directions. Witnesses are urged to call 503-823-3333 if they saw the accident or know the identity of those who fled.

We'll have more updates as we get them.
