Witness interviews were continuing, the sheriff’s office said. Investigators said there was no threat to the public.

Parents were directed to go to Bennett High School to reunite with their children. All children had been reunited with their parents by about 7 p.m.

School canceled Wednesday after shooting scare

School and all activities were canceled for Wednesday because of the “severity of the incident,” according to Bennett School District 29J.

The district said after the report of shots fired, the school responded immediately.

“The school went into a secure situation immediately to protect students during the volleyball game and after-school activities. We appreciate our family’s patience during the situation as we were following protocols given to us from law enforcement,” the district said in part in a statement to the school community.
