Oskaloosa Elementary And Emergency Services Continue Training For Worst Case Members of the Oskaloosa Police Department, Mahaska County Sheriff’s Office, The Oskaloosa Elementary, and Mahaska Health Emergency Services recently conducted a drill at the elementary school. Oskaloosa, Iowa – Tragic events are often broadcast to our television sets or we see the horrific images on our computer screen. To think that those images and events could be in our local community seem impossible, but local officials continue to train in the event the unthinkable happens locally. Oskaloosa Elementary Principal Mike Dursky said that the school recently partnered with area emergency responders to hold a hallway clearing drill.
