One fan died and three more were injured when a Toyota collided with a group of concert-goers at the Trail Ends campground in Huntsville after Adkins came off stage at the venue's Full Throttle event on Saturday night (23May15).

Billy Carson, 42, of Scott County, Tennessee was detained by police and charged with criminal homicide and reckless endangerment. Reports suggest he became embroiled in a fight at the venue before he allegedly drove his car into the crowd.

Tony Farrell, 52, was taken to hospital but later died of his injuries. His son was among those hurt.

Carson's bail has been set at $500,000 (£321,500) and he is set to be arraigned on Wednesday (27May15).
