A 19-year-old Air Force Reserve Officer Training Corps cadet died in an accident involving a HUMVEE during a training exercise on Friday at Saylor Creek Range in Idaho, officials from the Mountain Home Air Force Base said Sunday. 

"Today we lost a member of our Air Force family. We express our deepest sympathies to the families and friends of all the individuals," said Col. Ernesto DiVittorio, 366th Fighter Wing commander. "Our thoughts and prayers are with them."

MacKenzie Wilson, an Air Force ROTC cadet at Oregon State University who is originally from Alaska, was pronounced dead at the scene.
