SANTA FE, N.M. (AP) — Vandals set fires and torched furniture inside Pojoaque High School.
The fires set off the school's sprinkler system and that flooded a building for more than six hours.
Damage forced a two-day shutdown of the school, which isn't scheduled to resume classes until Friday.
A smoke alarm went off. However, authorities say it didn't alert fire dispatchers, allowing the sprinklers to run all night, dumping thousands of gallons of water.
