Upon completing the investigation, officials said that authorities found no evidence to suggest that the fire was intentionally set.

The cause of the fire is officially undetermined and has been attributed to several possible factors inside the residence, WBNS-10 reported.

Those factors include improper use of electrical cords, alternate winter heating methods, and hoarding.

Throughout the investigation, an extensive examination of the scene and interviews with people who might have known about the incident were conducted, WBNS-10 reported.

Around 7:30 a.m. on Nov. 23, 2023, volunteer firefighters in Athens County were called to an address on Rainbow Lake Road on reports of a fire, according to a previous News Center 7 report.
