A Kennewick woman critically injured in a fire last week that killed her mom is improving at a Seattle hospital.
Aireen Upton, 49, is in satisfactory condition and has been moved out of the intensive care unit, said a spokeswoman at Harborview Medical Center.
Upton escaped from her mother's burning mobile home Jan. 23 by jumping out a bedroom window. She suffered severe burns and smoke inhalation.
Elvira "Elvie" Pidcock, 65, died in the early morning blaze that destroyed the single-wide mobile home at 4815 W. Clearwater Ave. No. 35.
Fire officials still are investigating the cause. They are waiting for an opportunity to talk to Upton once she recovers to find out what she saw, said Mike Blatman, Kennewick police spokesman.
The fire appears to be accidental, officials said.
