A community in Utah is in mourning after its mayor, Brent Taylor, was killed in Afghanistan while he was deployed with the National Guard. It was his fourth tour of duty. With two months left in his year-long tour, the 39-year-old died Saturday after one of his Afghan trainees shot and killed him in an insider attack. The killer was in turn shot and killed. His body is scheduled to arrive in the U.S. Monday night. Brent leaves behind a wife and seven children. He is an American Hero.
