Civil rights leader Rev. Al Sharpton has offered a $50,000 reward for information leading to an arrest in the death of 18-year-old Nolan Wells, who was found dead following a Fourth of July trip with friends. The teenager's family and their lawyers say elements of the case are "not adding up" and have launched their own independent investigation, adding pressure on authorities to explain the circumstances of his death.

Sharpton made the announcement in connection with an NAACP event, where the family's attorney is expected to release the autopsy findings. Wells's parents have publicly questioned the official account of what happened during the trip, and the case has drawn wider attention amid calls for greater transparency from investigators.
