Fire investigators have been unable to determine the cause of a fire that killed one woman at Oswego Summit condominiums Aug. 29 and displaced 25 people.
Dedrea Decker, 60, was found dead on her back deck after the Mountain Park blaze, which damaged eight units in the condo complex and displaced dozens after it was initially extinguished.
Fire investigators have since determined the fire originated in the living room of Decker's condominium but said they were unable to determine its exact heat source, Deputy Fire Marshal Chaffin explained.
They are asking anyone who might have information on Decker's activities prior to the fire to come forward. Anyone with information is being asked to call the Lake Oswego Fire Department at 503-635-0275.
