More information about yesterday's bloody shooting on E. 91st. Street: The victim was a 21-year-old Duane Reade employee who was walking with a male friend when her ex jumped out at them. The berserk 24-year-old began pistol-whipping his onetime love in the face, a witness told the NY Post. "This guy comes out of nowhere with a pistol in his hand and starts beating her with it," he said. "The guy she was with got into a scuffle with this other man, trying to get the gun out of his hand. The gunman breaks away, gets a few feet away and then fires two shots...I don't see any blood at first, but her head started leaking and she started crying and screaming." The woman, who was hit in the arm and in the head, is still in stable condition. Both she and her ex-boyfriend live in the Bronx.
