FILER — Filer High School was placed on a soft lockdown Friday afternoon after a Snapchat message depicted a person students knew driving with a gun.

School officials were notified at 1:45 p.m. by students about the message, assistant principal Trudy Weaver said in a statement.

“While there was no articulated threat directed toward any person or any of our schools, we were concerned enough that we elected to go into a soft lockdown to ensure the safety of our students and staff,” she wrote.

Filer police investigated and the situation was resolved by about 2:30 p.m. The lockdown was lifted.

During the soft lockdown, school staff maintained constant supervision of all students, who were directed to stay indoors until they were able to secure transportation to leave campus. All students were able to leave safely.

It was the latest in a series of threats made via social media this week, affecting Magic Valley schools.

For four days, law enforcement and school officials dealt with social media threats against schools in Mini-Cassia. On Thursday, local and state law enforcement swept Declo High School after a threat mentioning a bomb at the school was posted on an Instagram account.

In Twin Falls, police are seeking a warrant for the arrest of a boy they say pulled a gun on students of Magic Valley High School at an intersection not far from campus. The incident happened after an argument between two students continued when classes dismissed, Twin Falls police said in a Friday statement.

A separate teenager, a 17-year-old, has been charged with conspiracy to commit aggravated assault, police said. Authorities would not disclose the names of the people involved.

Jerome police announced Friday a social media threat toward a Jerome High School student was false and “no actual, serious threat was present.”
