OCONTO – It was a homecoming for Oconto High School students Monday morning.

They returned to the building for the first time since a fire on April 16 caused about $5 million in damage.

Classes were temporarily held at the middle school, as crews cleaned the building.

The Oconto fire chief says a 16-year-old student started the fire while smoking in a bathroom. That bathroom has been repaired.

The Oconto County district attorney has the case. It's not clear if any charges will be filed.
