Lone Tree student arrested for threat against school, sheriff says

Johnson County deputies arrested a 16-year-old student following reports of a social media threat against a Lone Tree school.

According to a news release, the sheriff’s office was contacted by Lone Tree Community School officials at approximately 7 a.m. Wednesday about a threat sent by a student via social media. The sheriff’s office did not provide details about the threat or what social media platform was used.

Deputies responded to the school, and as a result of their investigation a 16-year-old student was taken into custody. The sheriff’s office said the student, who is not being named, is being held at the Linn County Juvenile Detention Center on a charge of first-degree harassment.

The investigation is ongoing, the sheriff’s office said.

Johnson County Sheriff Lonny Pulkrabek said school was in session Wednesday, but the threat was reported before classes began. The school was put on partial lockdown — all the all the doors except for the main entrance were locked, so students and staff would funnel in through one entrance, he said.

Pulkrabek said officers will remain on campus until classes let out. The school is releasing students early on Wednesday ahead of the Thanksgiving holiday. The elementary, middle and high schools share the same building.

In a statement to parents, Superintendent Ken Crawford said, “Quick efforts by Lone Tree staff and Johnson County law enforcement concluded this incident almost immediately. At no point during the investigation did the school district or law enforcement believe students were in danger.”

Crawford encouraged students and parents to “continue to follow the ‘If You See Something, Say Something’ protocol and report suspicious activity when they see it.”


“It is reassuring to have a community that works together with the school and law enforcement to ensure the safety of everyone,” he said.
