A Jackson, Mississippi grand jury returned a unanimous, “no true bill” in the death of 18-year-old Nolan Wells. The jury determining there was not enough evidence to find anyone criminally responsible for the death of the black teen who was last seen partying with friends on an island off the Mississippi coast on the Fourth of July.   Instead, the grand jury found that Wells’ death was consistent with drowning, but his official cause of death remains undetermined. Wells’ attorney said “Nolan’s family will not rest until we know what happened to him, and neither will we.”
