Investigators still are searching for the cause of Monday's mobile home fire that killed a Kennewick woman and severely injured her daughter.
Nothing suspicious has been found, said Kennewick police Sgt. Ken Lattin, and everything appears to point to the fire being accidental.
Fire investigators, however, continue sifting through the charred rubble at 4815 W. Clearwater Ave., No. 35, to try to pinpoint an area of origin or cause of the early morning blaze.
Elvira "Elvie" Pidcock, 65, died in the fire. Her daughter, 49-year-old Aireen Upton, was able to escape the 3:20 a.m. blaze by jumping out of a bedroom window.
Never miss a local story.
Upton is in serious condition in the intensive care unit at Harborview Medical Center in Seattle, a hospital spokeswoman said Wednesday.
