The five-alarm fire early Monday morning has been ruled accidental. According to Zanesville Fire Chief Dave Lacy, the blaze caused over $125,000 in damage. The state Fire Marshall was involved in the investigation because of the amount of damage to the Ridge Avenue Furniture and Appliances store. Lacy says his crew went through the store piece by piece to determine the cause. With stores on fire, they never rule out burglary and arson.
