COLFAX, WA – Multiple local agencies will take part in an active shooter mass casualty training exercise at Colfax High School on Wednesday, June 18, 2025. The training is scheduled to run from 9:00 a.m. to 3:00 p.m. and will involve emergency responders from across Whitman County.

Organized by the Whitman County Department of Emergency Management, the drill is a joint effort involving school officials, ESD 101, fire and EMS personnel, law enforcement agencies, and Whitman Community Hospital.
