it's pretty spooky because you can see the gym lights are on, and when the wall gets wrecked you can also see it's probably late in the morning or sometime in the afternoon. with the lights being on, that probably means it was being used that day.
for all we know, that school's classes were somewhere in a basement or got sent home a few moments earlier
