Police say a suspect has been charged with second-degree murder in the death of former New Orleans Saints defensive end Will Smith, who was shot and killed Saturday night. New Orleans Police Department spokesman Tyler Gamble on Sunday identified the suspect as Cardell Hayes, 29. Gamble said the investigation was ongoing but did not release further details. Authorities say Hayes killed Smith after the two argued following a traffic accident in New Orleans late Saturday. Smith, 34, was pronounced dead at the scene. Police say Smith's wife was also shot and taken to a local hospital for treatment.
