Nolan Wells’ death is still under investigation, but a rescuer who helped search for the missing football player believes the dangerous waters around Mississippi’s Horn Island could explain what happened. Brian Trascher, national vice president of the United Cajun Navy, told The U.S.

Nolan Wells disappeared during a Fourth of July trip to Mississippi's Horn Island. His body was found two days later.

GPS data from the Mississippi Department of Marine Resources, obtained by CBS News, tracks the movements of the boat that carried Nolan Wells to Horn Island on July 4.
