CNN) -- Panicked customers rushed to the exits when a gunman opened fire Tuesday at a mall outside Portland, Oregon. Some people huddled behind store counters and hid behind racks of clothing. The mall's Santa dropped to the ground.
A witness told CNN he tried to help a wounded woman who was lying on the ground by a cell phone store.
"She had apparently been shot in the chest, and I couldn't get her turned over to help her," said Antonio Charro, who had been shopping at the mall with his daughters. "There was no one around. She wasn't breathing."
