Three people have been charged with threatening a judge, a witness and local officials connected to the investigation into the death of Nolan Xavier Wells, an 18-year-old found dead after a July Fourth boat trip with friends to an island off Mississippi's Gulf Coast. None of the three appear to know Wells, his family or the boating group, or be part of the investigation. The threats came amid rampant speculation and scrutiny of the investigation, deepened in part by uncertainty surrounding Wells' final hours, distrust of law enforcement and the state's long history of racist violence. The teenager, who was Black, had traveled to the uninhabited island with a group of friends from high school, all of whom were white. He did not return with his friends to the mainland that evening. His body was found two days later off the island's coast.
