In the renowned US theme park "Sea World", Dawn Brancheau, a professional trainer, was killed on Wednesday by a killer whale while playing with it from a poolside platform.  

The 12,000 pound sea animal snatched Brancheau with its jaws and dragged her underwater, where she died.  

A whale expert insists that because of killer whales' high level of intelligence, the attack must have been "pre-medidated and intentional".

It's the third death linked to this particular killer whale.
