Residents of duplexes in West Linn awoke to popping sounds and then yells to get out when fire swept through one of the buildings.
The duplexes are located on Ostman Road.
Tualatin Valley Fire and Rescue crews called a second alarm to get enough equipment to fight the fire and to keep it from spreading to a neighboring building.
All residents escaped safely. Firefighters rescued three cats and used a special oxygen mask to revive one of the cats.
Eight adults and three children have been displaced as a result of the fire and American Red Cross is helping them with housing and immediate needs.
Based on preliminary interviews and evidence, the investigator has determined that unattended cooking was to blame for the blaze. The fire was fed by natural gas, which added complexity to the incident.
While firefighters were still tending to hotspots at the West Linn fire at 2:42am, TVF&R responded to another fire SW 8th Street and Main Street in Beaverton. First-arriving firefighters from Beaverton Station 67 found a two-story home with fire coming out of two sides. Firefighters initially fought the fire from the outside and transitioned to an interior fire attack where heavy smoke filled the home. Though they had information that no one was inside the home, they still conducted two searches to be sure.
Firefighters contained the fire within 30 minutes were able to limit damage to the home, but the garage was a complete loss.
The resident tells KATU News that he was smoking trout in the garage and that might have started the fire. An investigator will determine the official caused.
The family's cat was killed in the fire.
