(KAIR)--The Doniphan County Sheriff's Office, following a mock disaster drill Thursday, is sending its thanks to volunteers, Troy High School, and others, who worked to make the effort possible.

According to a release, the mock drill revolved around an active shooter scenario at the high school, with volunteers serving as victims who called an emergency service phone number which connected them to dispatch, with dispatch then relaying the information to first responders, who were provided with little information in advance of the drill. Using the information given to dispatch by volunteers, those "first responders developed a plan to eliminate the possible threat inside the school and form a plan to extract injured victims out of the school and away from any more danger."

The training also involved officers searching for the shooter inside the school, leading up to the first responder response.

The training concluded with a Life Star Air Medical Service landing on the football field to transport a mock, injured victim to the hospital.

The release, issued by the Doniphan County Sheriff's Office, closes by saying that due to the support from those involved, "first responders were able to train together to be able to better serve" the County.
