If you're going to post about the other killings, at least get your facts straight. You post it like it's something he's done several times, like it's nothing new.
He was new whale at the aquarium, with two other female whales in the same tank. One of them being pregnant. When the accident happened, and the trainer fell into the tank.
The second death was the cause of the person's stupidity. He got into 55 degree water at night. There was nothing to show that Tili did anything to the guy to cause his death. I hope that was the last thing on his "life's to do list"... because it sure was a stupid one (to fulfill in that way).
This death is right now considered an accident. They're not releasing much information. And no one gets into the tank with Tili like the other whales. It happened during Dine with Shamu, so I'm sure there's witnesses to it, but don't expect them to be talking or to see video of something like this.
