Surveillance footage taken late Saturday in New Orleans’ Lower Garden District may offer some clues in the shooting death of former New Orleans Saints defensive end Will Smith. The footage show a Mercedes SUV trailing a Hummer, until the latter vehicle stops abruptly. The Mercedes pulls up quickly, too, possibly hitting it from behind. Both vehicles are a standstill briefly, until the Hummer starts to pull over; the Mercedes, though, goes around and drives off. A short distance away and a short time later, according to police, an altercation occurred between Smith, in a Mercedes G63 SUV, and Cardell Hayes, in a Hummer H2. This time, it was the Mercedes that was rear-ended, police said. Hayes didn’t drives off after rear-ended the Mercedes and which led to Smith being dead and his wife shot in the leg.
