On Feb. 20, 2018, Jackson Memorial Middle School in Ohio was the scene of a fatal, self-inflicted, shooting involving a 13-year-old male student. This immediately made the middle school, and all Jackson local schools go into lockdown mode. Fire, EMS and law enforcement agencies converged on the scene and began operations. The initial intelligence reported that this was the first step in a planned mass school shooting. The event went from a suicide to a large-scale operation. This class will explain the course of events of handling the school shooting emergency to all skill levels. Lessons learned will be examined, with each layer of the event, as they unfolded.
