(MCT) — Nick Viverito says he and his best friend William "Chris" Pettry were enjoying the Florida evening, laughing and socializing with other Bears fans who had traveled to Jacksonville for Sunday's game.

They briefly chatted with a man and his wife and another woman waiting for seats at the Irish restaurant and bar.  The man and the women went inside and, a little later, Pettry also left to buy a round of drinks. He never came back out.
