New audio released following Nolan Wells disappearance doesn't show 'anything nefarious': retired FBI agent

A retired FBI agent says that new audio released following Nolan Wells' disappearance and death doesn't show "anything nefarious." Wells, 18, went missing July 4 after a boat trip with friends to Horn Island, a barrier island off Mississippi's Gulf Coast. Crews searched the area for two days before a National Parks Service ranger found his remains on the island's northwestern tip on July 6. Wells' friends returned to the mainland that afternoon without him. Jackson County Sheriff John Ledbetter
