Investigators with the Green Bay Metro Fire Department say the cause of a fire that sparked at Aldo Leopold Community School back in June has been deemed undetermined.
Classes are back in session for the school year, but questions still remain about what happened.
Nobody was inside the building when the fire started, but there was enough damage to affect classes for the rest of the week.
Green Bay Metro Fire Department Lieutenant Shauna Walesh said investigators deemed the cause of the fire as undetermined.
Lieutenant Walesh says there were four separate possibilities from the incident as to why the fire started, but investigators were not able able to confirm any of those.
Lieutenant Walesh said the first hypothesis was that the fire occurred as a result of combustibles being placed too closely to the kiln. The second was that the fire was a result of a malfunction of the touch pad on the kiln. The third possibility was that the fire was the result of an LED panel malfunctioning in the drop ceiling of the kiln room. The fourth hypothesis was that the fire occurred as a result of an electrical wiring malfunction in an unoccupied space.
