Two detectives, including the undercover who fired the first bullet in the 50-shot barrage that killed Sean Bell, told their story yesterday to the Queens grand jury that will decide if any of the five officers involved in the sensational case should be indicted.
Det. Gescard Isnora's appearance, plus that of Det. Marc Cooper, sets the stage for the much anticipated testimony tomorrow of Det. Michael Oliver, who fired the most shots, 31, reloading his weapon in the process.
