Multiple law enforcement agencies, including the Missouri State Highway Patrol, are now investigating three different false reports or swatting calls claiming there were active shooters at three different schools.Investigators believe the same caller with a thick, hard to understand, foreign accent made all three calls.The false reports were made about North Kansas City High School or Northtown, Smith Cotton Junior High in Sedalia and Knob Noster High School.The calls were made Monday, the same day as fatal shootings at a Nashville, Tennessee school.Clay County Sheriff’s Deputy Mathias Kerekes and North Kansas City Police Officer Jason Smith, both Northtown school resource officers, were on duty Monday when the swatting call was made to the non-emergency line of the North Kansas City Police Department claiming a mass shooting was underway in a school bathroom.The school was put on a “lock and teach” meaning nobody could leave the rooms they were in.Kerekes and Smith quickly determined the call was a hoax and the “lock and teach” lasted only six minutes.“It's definitely frustrating just because it kind of scared us a little bit. You know, we were just doing our work and then we get the announcement,” said Breck Brown, a Northtown student.“It's sad that we have to have to have things like that happen. Issues like that happening during school hours is just not something I want to worry about when I'm coming here to learn every day,” said Jackson Baehr, a Northtown student.Even though the lockdown only last six minutes, it prompted a large response from the Clay County Sheriff’s Office.“It was pretty easy to determine that it wasn't legitimate. But we sent every resource we had as fast as we could just regardless,” said Sarah Boyd, Clay County Sheriff’s Office spokeswoman. “We’re over 400 square miles in Clay County and all of our deputies who were not on a call were in North Kansas City, the very southern part of our county. So, if someone needed us up in Holt, for instance, that would take quite a while for response time,” she added.The swatting call also prompted Northtown Principal Drew White to send an email to families explaining what happened.White noted there was a similar swatting incident at the school in September.“Unfortunately, these type of hoax incidents are becoming common in schools. I know this is frustrating for our entire school community, and I am frustrated, too. However, just as we do with any report, we must take all concerns seriously and act to ensure students’ safety,” White wrote in the email.Investigators also say the swatting call Knob Noster High School came right as the Smith Cotton Junior High School scene in Sedalia was being cleared.Unlike the school shooting scene in Nashville, the Missouri schools threatened with the swatting calls all have armed school resource officers.“I think it's important to have somebody here that makes the students feel safe. It helps the parents feel safer about their kids,” Baehr said.But Melissa Furgurson, a parent of a Northtown student said the email about this latest swatting incident bothered her.“It really takes a sick person to do that because it's really nothing to joke about,” she said.Under Missouri law, a swatting call in a class “E” felony punishable by up to four years in prison and a $10,000 fine.
