OCONTO, Wis. -- The cause of a fire that devastated Oconto High School is no longer a mystery.
Investigators calling it an accident. The school had to be evacuated on April 16th after the fire started in the boys bathroom spreading throughout the building.
It was a hand rolled cigarette belonging to a 16 year old student. That caused five million dollars in damage. Damage that has restoration crews working hard to get three hundred students back into their school.
It took a week to investigate now Oconto Police have found the cause thanks in part to school video and interviews a 16 year old student smoking in this bathroom then leaving it close to a toilet paper dispenser.
"A toilet paper roll that looks like what caused the main source of heat," says Fire Chief Jack Mlnarik
