A swimmer was attacked by a shark off of Camp Pendleton's San Onofre Beach Saturday evening. The victim was airlifted to Scripps Memorial Hospital in La Jolla, said Camp Pendleton Sgt. Asia Sorenson. The incident was reported shortly before 6:30 p.m., Sorenson said. "We can confirm it was a shark bite, but the extent of injuries is unknown at this time," Sorenson said. Sorenson said only that the victim is a civilian, but that she could not confirm the age, sex or identity of the victim. The Orange County Register quoted a state park aide who said that the victim was a female who was wading in the water near a surf spot called "Church" off of Camp Pendleton campgrounds. The aide, Travis Lara, said the woman was bitten "on her glute and down her thigh." A report by NBC 7 San Diego quoted a witness, Hunter Thompson, who helped bring the woman to shore on a surfboard, saying she was bitten from her hip to her leg.
