A Mercer County, KY, deputy is out of surgery and stable in the intensive care unit after he had a heart attack during an active shooter response training Saturday.

According to WTVQ-TV News, Deputy Bill Cruce dropped to the ground in the middle of the drill.

First responders present to participate in the training quickly came to Deputy Cruce's aid.
