Email I got from the school:
XXXXXXX Hall continues to be closed to all activity. Afternoon classes in that building, including the 1:00 p.m. classes, have been cancelled due to an ongoing arson investigation.
An update to this situation regarding evening classes will be sent at 4:00 p.m. today.
Individuals who have personal items in the building that they need to retrieve should contact one of the police officers posted at the building.
