Store clerk fatally shoots masked gunman By BILL MILLER Star-Telegram Staff Writer A clerk fatally shot a masked gunman in an exchange of gunfire at an east Dallas convenience store late Tuesday, police said. Anthony Jerome Davis, 17, died at 12:43 a.m. at Baylor Medical Center of Dallas, said Senior Cpl. Janice Crowther, a Dallas police spokeswoman. The shooting occurred at 9:32 p.m. Tuesday in the 300 block of St. Augustine Road, Crowther said. ``Apparently, this man came into the store wearing a mask,'' Crowther said. ``The store clerks realized immediately that they were about to be robbed, so they took cover behind the counters. ``The man said, `Don't run,' and fired a shot at one of the clerks.'' The clerk got his own gun, Crowther said, and fired back at Davis, fatally wounding him. Crowther declined to give the clerk's name because he has not been charged with a crime. She noted, however, that the case would be reviewed by a Dallas County grand jury, which is routine.
