Tyler Poulson, a 21-year-old man, was riding with his brothers in South Jordan, Utah when he became offended by one of them using profanity.
Tyler had just returned from an LDS (Latter-day Saints) mission, and threatened that he would exit the moving vehicle if the profanity continued. One of the men told Poulson to, not thinking he would.
The truck was going about 35 mph when Tyler just opened the door and jumped out. He was pronounced dead at the scene.
