NASHVILLE (AP) - Jason Aldean's tour bus struck and killed a man on a highway in southwest Indiana early yesterday. Knox County Sheriff Michael P. Morris says the bus hit a man identified as Albert Kennedy of Vincennes, Indiana. Kennedy was pronounced dead at the scene. Morris says only Aldean and his driver were on the bus at the time, and no charges will be filed. He says the accident was "unavoidable" and Kennedy was known to walk or bike along that road. Aldean tweets that in all the years he's been touring, nothing prepares anyone for something like this to happen. He says he's praying for Kennedy's family and asks fans to do the same.
