HERREID, S.D. (KELO) — The Herreid School is closed Thursday as authorities investigate an incident involving a weapon.

A Sioux Falls woman is in jail charged with making terroristic threats that led to no school at Herreid.

According to law enforcement, Mercedes Klingman, 44, told authorities there was a man with a gun at the school on Wednesday. The Herreid school was evacuated and searched.

Law enforcement searched the school building and outbuildings and determined that there was no threat. Out of caution, the school district decided to cancel classes.

On Wednesday, shortly after 4 p.m. the Campbell County Sheriff’s Department contacted the Herreid School and told them of a possible threat. The sheriff’s department asked the school to immediately clear the building.

A deputy pulled Klingman over and during the stop she told him she had dropped off a man with a gun at the Harried School. According to the deputy, she then sped away. The deputy chased and clocked her at 115 miles per hour.

The report says during the chase she called 911 and again reported a man with a gun at the school. The deputy was forced to abandon the chase and head to the school.

It was later determined there was no man with a gun; the sheriff’s office believes it was a ruse by Klingman to get away.

She was later arrested in Mobridge.

On the school’s Facebook page, one parent is praising the sheriff’s department for its diligence. Other posters are expressing their anger and frustration that something like this can happen in their small, close-knit community.

Klingman is charged with felony terroristic threats, felony aggravated alluding, possession of a stolen vehicle, Reckless driving and obstructing law enforcement.
