FOND DU LAC, Wis. (WBAY) - The Fond du Lac School District says only about a quarter of students at Fond du Lac High School showed up to class Monday after word spread of a social media post warning there would be a shooting (see related story).
Tuesday, things were back to normal with school safety at the front of people's minds.
"I think students, especially with the leadership some of the Florida students have shown, are really taking that active measure of saying they're our ears and eyes of the school," Principal Matt Steinbarth said. "They know what's going to happen before any teacher, any administrator knows, so they're taking it upon themselves to make sure that they're safe and that their classmates are safe as well."
Fond du Lac authorities say a number of students brought the Snapchat post to the attention of teachers and parents.
Investigators were able to track it back to Arkansas by working with the social media company.
Police say a 16-year-old boy who used to have ties to the area admitted writing the Snapchat post. Police later arrested three Fond du Lac boys who attend Fond du Lac High School, saying they concocted a plan with the Arkansas boy to get a day off from school.
Investigators found no evidence the boys planned any violence, but the Fond du Lac boys were referred to juvenile authorities on a charge of Party to the Crime of Making a Terrorist Threat. Police are working with Arkansas authorities on possible charges against the teen there.
"In this case again, it proved you bring those serious allegations or those serious concerns about a social media post forward we're going to investigate it, we're going to find out who sent that post, and we're going to hold them accountable," Assistant Police Chief Steve Klein said.
The school district and police hope this is another reminder that posting on social media can have a lasting impact.
