Unfounded bomb threat to Columbine High sends 23 schools into lockout

National News

DENVER (KUSA) – All students and staff at Columbine High School are safe after someone threatened the school Thursday morning — causing it and 22 other nearby schools to be placed on a lockout.

Around 9:20 a.m. Thursday, a caller claimed to have “multiple explosive devices” inside the school and be hiding outside of the school with a gun, according to Mike Taplin with the Jefferson County Sheriff’s Office.

Columbine, site of the horrific 1999 massacre, was placed on lockdown for a short time. 22 other schools in the Jefferson County area were placed on lockout while police searched.

“So far we’ve not found anything to validate any of the claims made in the threats,” Taplin said in a press briefing just after 1:00 p.m.

All 23 schools remain on lockout status, meaning no one can enter or exit the schools.

Police will remain on scene as the investigation is ongoing. Taplin assured that staff and students are safe.

“Unfortunately we receive many threats throughout the year regarding Columbine High School,” Taplin said. “We respond to each of those threats appropriately.”
