Six months after a sea lion snatched a little girl off a dock, it’s happened again. Three people have been attacked by aggressive sea lions at the same location. One victim is 56-year-old Christian Einfeldt, who was swimming at the popular Aquatic Park Cove in San Francisco. He says a 400-pound sea lion bit him on the arm. Christian was hospitalized last week and had two surgeries. He's also receiving shots just in case the sea lion has rabies.
