The home at 653 J.H. Fauver Road near Blountville was entirely engulfed when a neighbor saw the flames after hearing what was thought to be an explosion at 2:30.
Volunteer firemen extinguished the fire and discovered the body of Lannie Mae Fauver, 61, inside the remains of the mobile home.
Fire and arson investigators from the Sullivan County Sheriff’s Office responded to the scene and will be conducting an investigation into the possible causes of the fire. The investigation is expected to take at least several days.
