INDIANAPOLIS (WISH) — Mooresville Schools says the discovery of a police training device on school grounds, not a violent threat, is what prompted an e-learning day on Thursday. The school district said around 6:45 a.m. that it was shifting to e-learning due to a “threatening situation.” Less than two hours later, it posted a statement on Facebook to explain what happened. “This morning’s situation involved a suspicious item found on the Mooresville High School campus,” the district said in a statement. “It has been determined the item was part of Wednesday overnight training from the Morgan County Sheriff’s Office.” The item was left behind when officers left for an urgent call. Custodial staff discovered the item early Thursday morning and notified administrators. “We are incredibly thankful to the school custodial staff for their daily campus checks and their immediate alert,” Mooresville Schools said. “We are also thankful to our Mooresville Schools Police Department for their immediate response. We do not regret taking full measures to keep students safe and will always do so.” All Mooresville students will remain on e-learning on Thursday. After-school practices and activities will take place as normal. Original story below. INDIANAPOLIS (WISH) — Students and teachers at Mooresville Schools are being told to stay home on Thursday due to a “threatening situation.” Instead of holding in-person classes, the district will be on an e-learning day. “All students will be on an asynchronous, non-livestream learning schedule. Students should check Canvas and Google classroom for lessons,” Mooresville Schools said on Facebook. The school district did not give any details about the threat, saying only that “school officers and administrators are working actively with law enforcement to fully assess the situation.” In the last few weeks, threats have been made against a number of Indiana schools. Richmond Police said Thursday that a 14-year-old was arrested for putting a threat against a high school on Snapchat, while two Lake County juveniles face charges for making school shooting threats. Two children, including an 11-year-old girl, were arrested on Sunday after the two made threats against various schools in central Indiana.
