Maryville Public Safety is no longer investigating the fire that occurred Sept. 14 at 123 S. Mulberry St. as arson.
According to Maryville Public Safety director Keith Wood, nearby cameras did not detect foul play.
Investigators originally thought the fire began on the back porch. Camera footage from a nearby resident’s house said otherwise.
“We could see the point of origin or what we had identified as the point of origin and there was nobody visible on that tape in the immediate area just prior to the fire,” Wood said.
The source of the fire is still unknown.
“We probably still have as many questions as we do as answers,” Wood said. "I can’t necessarily say how it did start but I can say how it did not start.”
Maryville Public Safety had announced the fire was being investigated as arson on Monday.
Officials responded to the fire late in the afternoon Sept. 14.
The resident was not home at the time of the fire. One family pet died in the fire, two escaped and have since been found.
A GoFundMe has been set up to support those impacted by the fire.
