Authorities were able to identify the body following an autopsy.The woman was pronounced dead at the scene of the blaze at a home in the 400 block of Roy Avenue, on the city’s southeast side. The fire was reported at 3:25 a.m. on Saturday, Sept. 5.Ross’ body was discovered after firefighters extinguished the blaze and began overhauling the scene.The body was found in the master bedroom in the home’s southeast corner, the same area where the fire appeared to have originated, Warrenton Fire Chief Mike Owenby reported.No official cause of the fire has been determined, Owenby said, though it appears to be accidental.The investigation is being handled by the state fire marshal’s office.“We do not know the cause yet,” Owenby said. “It will likely be awhile. These things take time to get completed.”When the first firefighters arrived on the scene, Owenby said flames were shooting through the roof. He said crews were able to quickly knock down the fire.Warrenton firefighters were assisted by crews from Wright City, Marthasville, Wentzville, Hawk Point and Jonesburg. Crews were on the scene for around 7 ½ hours, Owenby said.No other occupants were in the home at the time of the blaze. Owenby was unsure if the fire was reported by a neighbor or a passerby.Fatal fire
