Four others who were at the game and fled from police in a vehicle after the shootings, authorities said, have been identified as Michael Mack, 27; Tyrell Dorn, 28; Shahid Dixon, 27, all of Atlantic City, and Vance Golden, 26, of Pleasantville. One of those men — police have not said who — threw a gun out of that vehicle and onto the roadway as it neared Atlantic City, authorities said. The gun was recovered by police, and the four have been charged with unlawful possession of a weapon and with being certain persons not to possess a weapon.
