Reports of a possibly armed person at Elk Grove High School prompted authorities to place that campus on lockdown during the afternoon of May 21. Investigators later learned that the perceived gunman was actually a student who used an open stapler to act out a movie scene.

The lockdowns at Elk Grove High and nearby Florence Markofer Elementary School were soon lifted.

“We take all threats seriously – this was reported as a perceived threat and we responded,” said Xanthi Soriano, the spokesperson for the Elk Grove Unified School District.

The lockdown started shortly after classes were dismissed at noon. Soriano said that a school official initiated the lockdown and prompted campus security and law enforcement to respond.

She noted the challenge of having the lockdown after class dismissal – she said that students who remained at the campus were told to stay. Students at Joseph Kerr Middle School were also redirected back to their campus at Elk Grove Boulevard.

Elk Grove police officers as well as officers from outside law enforcement agencies arrived at the campus that’s near the corner of Valley Oak Lane and Elk Grove-Florin Road. They performed a “precautionary sweep” of the campus while the investigation commenced. The Elk Grove police used their Facebook page to tell people to avoid the area.

The lockdown was reportedly lifted at 12:44 p.m. after investigators contacted the student who carried the stapler and determined there wasn’t a threat.
