First responders in Washington and Benton counties in Washington state held a multi-regional active shooter response drill at Farmington High School. The drill included police, fire and agencies from across the region, including staff from the high school.

Participants held a tabletop scenario where everyone discussed a slow walk-through to respond to a situation, defining roles and responsibilities, before participating in the live drill.

The live drill was a response to a situation involving an active shooter or an "aggressive person."
