A social media threat to Taylorville High School was deemed not credible after the school district and area law enforcement worked overnight Thursday into Friday to determine the threat’s authenticity.

Taylorville Police Chief Brian Hile says after investigating, they could not track the post back to a Taylorville student.

Hile says this is not an isolated incident. There was also a threat at Mattoon High School overnight and an arrest was made there.

Taylorville High School Principal Matthew Hutchison says there was extra police presence on campus today, but it ended up being a regular day at THS.

Hile and Hutchison say the biggest priority is the safety of the kids, and they treat all threats very seriously.
