Sargent County Sheriff Travis Paeper says she was 39-year-old Denise Luttio-Mahar. Paeper says she lived in the rental home. Luttio-Mahar called 911 and reported that there was smoke inside the house. While she was on the phone with emergency dispatch, contact was lost. She was taken to the hospital in Lisbon where she died. A man in the house managed to escape along with two dogs. One dog died in the blaze.
