i'm surprised it took as long as it did. >> first tonight, a six ton killer whale has lived up to his name killing an experienced trainer at seaworld orlando today. >> a tourist at an earlier show said the animal seemed agitated. >> trainers complained the whales weren't operating. >> the whole show, the main show was a disaster that day. >> there were whales chasing each other. and eventually the trainers decided that they had to stop the show because they couldn't get the whales under control. >> tilikum was in the back pool set up to do a dive shamu performance with dawn. >> likely she saw what had gone on during the main show, and so she had probably felt more pressure to do a good show. when you watch the whole video, you can see that tilikum is actually really with dawn in the beginning of the video. there's a couple of behaviors she asked him to do where tilikum jumps right in and does exactly what she asks him to do.
