Killer whale kills.

"The trainer was explaining different things about the whale and then the trainer that was down there walked away from the window. Then Telly (the whale) took off really fast in the tank and he came back, shot up in the air, grabbed the trainer by the waist and started thrashing (her) around. He was thrashing her around pretty good. It was violent."

ADDED: Theme park visitors were sitting there eating dinner — "Dining with Shamu" — next to a window to the whale's tank. Imagine biting into your food — thinking you're in this lovely, desirable environment — and seeing the whale swimming around with the dying woman in its mouth.
