The last day of school marked a first for Owatonna High School seniors.
Firefighters say curtains in the school auditorium caught fire. They describe it as "minimal" smoke, fire, and water damage. The water damage was caused because sprinklers went off inside the school.
"Sprinkler systems are huge," said Owatonna Fire Chief Mike Johnson. "In this case, the sprinkler system saved the school."
As graduating senior Nash Dushek put it, "oh that was a very interesting last day."
Johnson says they're still investigating the cause of the fire. Several tweets suggested the fire may have been part of a senior prank, but Dushek doesn't think that's the case.
"It wouldn't be a senior prank to do that," he said. "Owatonna has so many more morals and so much better standards than that. I don't believe anybody would do that."
So chalk this up to one more memory for the senior class legacy - just like their t-shirts say.
"It said end with a legacy," described Nash, "so we really made our mark i guess, a memorable last day."
Johnson said he believes Owatonna High School will be back in session Thursday for underclassmen.
