Nolan Xavier Wells, an 18-year-old who was found dead after a July 4 boat trip with his friends to a Gulf Coast island, was remembered in Mississippi. The service began Monday with a prayer from the Rev. Al Sharpton, followed by speeches from Wells' parents, who described their son as a warm, gentle presence and role model to his younger siblings. Wells' death has sparked national attention and calls for a deeper investigation. Wells, who was Black, traveled by boat to the island with his friends, who are white. He didn't return with them to the mainland. His body was found two days later. The investigation remains ongoing.
