Reasons Why the Killer Whale Attacked Its Trainer

After animal trainer Dawn Brancheau was drowned by a killer whale in front of an audience, experts have several theories on why the animal has attacked and killed its own trainer.

•    Killer whales are naturally playful animals and the one that killed the trainer may have been bored inside the aquarium.
•    Something or someone might have agitated the animal, causing it to drag Brancheau under water.
•    The animal has experienced severe stress, probably causing it to snap.
