According to Mike Stangel, building operations manager for the Green Bay Area School District, an intrusion alarm went off around 1:40am. The alarm company came to the school and noticed smoke instead of an intruder.
It took firefighters a few hours to get the fire under control. Heavy smoke could be seen pouring from the rooftop and could be smelled blocks away.
"On arrival, police department and fire department crews did report heavy smoke showing to the point that it was completely obscuring the street," Battalion Chief Rob Goplin said. "We made an interior attack and we did locate a fire in the gymnasium."
Stangel confirmed the fire started at the end of the bleachers, where no wires or any combustibles were located. School officials and law enforcement are reviewing security cameras to see if anyone was inside the school at the time of the fire.
"It's pretty shocking. I'm saddened really," recent Preble graduate Brittany Rupp said as she watched crews go in and out of the school. "A lot of great things happened in these halls and I'm just wondering how or why this would have happened and it's just kind of scary and sad at the same time."
Stangel says there is no sprinkler system in the gym section of the building.
The Brown County Fire Investigation Unit is on scene to find out what sparked the blaze.
All activities at Preble High School are cancelled for Friday, according to the school district. Any further information about the school and activities would be released as soon as possible.
"We will be informing you as soon as we can," Barbara Dorff told Local 5's Wendy Fleury. "Give us maybe a couple of days to figure out what is going on, but we will definitely, absolutely communicate with our families and if it's possible to do that through social media, through the media, through text messages, whatever, we will be communicating but we need their patience too because it's going to take us some time."
