that's why all our interactions are very carefully thought out, especially our water work interaction. wow! >> you big dork! especially our wart work interactions, because they're potentially the most dangerous. >> i've been expecting it since the second person was killed. i've been expecting somebody to be killed by tilikum. i'm surprised it took as long as it did. >> first tonight, a six-ton killer whale has lived up to its 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 cooperating. >> the whole show, the main show, was a disaster that day. >> there were whales chasing each other. and eventually the trainers decided 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 dine with shamu

performance with dawn. >> likely she saw what had gone on during the main show. she probably felt more pressured 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 that she asks him to do where tilikum just jumps right in and he does exactly what she asks him to do. >> there seemed to be a point in the session where things went south, to so speak. and in my humble opinion it was at that missed bridge, whistle bridge on the perimeter peck wave. >> she asked him to do a perimeter pec wave where she asks him to basically go all the way around the pool and wave his

pectoral flipper. and she blows her whistle, which is a bridge, which tells the animal that okay, you've done a good job, come back and get food. but he missed that cue. and he went all the way around the pool on this perimeter pec wave. >> my interpretation is that he didn't hear the whis gel so not only did he not hear the bridge, then he went and did a perfect behavior and came back, and what he got was what we call a three second choice which is the way to let the animal know, no, you didn't do the correct thing. you're not going to get rewarded. then we're going to move on you. can also see through the video that dawn is running out of food. >> the animals can sent when you're getting to the bottom of your bucket of fish because they can hear the ice clanging around and the kind of fishy, soupy water at the bottom. and the handfuls of fish they're getting delivered by the trainer are all getting smaller. so they know that they're coming down to the end of session.

>> when you see the difference between the beginning of the video and the end of the video, you can see that he's just not quite on his game anymore. >> there's no food left. she kept asking him for more and more behaviors. he wasn't getting reinforced for the behaviors that he was doing correctly. he probably was frustrated towards the end. >> then she walked around the perimeter of g pool. he followed her. and then continued over into the rocky ledge area where she laid down with him to do a relationship session, which is -- it's quiet time, basically. tilikum at some point grabbed ahold of her left forearm and started to drag her. and eventually did a barrel roll and pulled her in may have started as play or frustration, and clearly escalated to be very violent behavior that i think was anything but play. in the end, he basically just

completely mutilated that poor girl. >> they were gathering all the trainers at the texas park. he said, there's been an accident at the florida park, and a trainer was killed. hearing that it was dawn, i was -- i couldn't believe it. i just remember saying to myself, not dawn. it can't be dawn. he said that -- and he still has her. and i just was so disturbed by that and the reality of how powerless we are. >> laceration, abrasion, fractures, frarkss associated hemorrhages, blunt force traumas to the main body, to extremities. to see this meted out against a trainer. and i cannot fathom the reason.

it's shocking. >> a lawyer for osha asked me what i thought we'd learned. and i'm sitting in the courtroom, and i've got the kelty burn case file in one hand and dawn branscho almost 20 years apart. my answer was not a thing. they've not learned a damn thing for that thing to happen 20 years apart. britta olsen is my . i spend long hours with her checking her heart rate, administering her medication, and just making her comfortable. one night britta told me about a tradition in denmark, "when a person dies," she said, "someone must open the window so the soul can depart." i smiled and squeezed her hand.

new tonight, seaworld has confirmed a killer whale pulled a woman into the wart. she didn't fall into the tank as the sheriff's department initially reported. >> the new plan is that he grabbed her pony tail. this is a subtle way of placing the blame on dawn's shoulders. she shouldn't have had a long ponytail. if she did should have been up

in the bun. >> dawn if she was standing here with me right now would tell you that was her mistake in allowing that to happen. >> they blamed her. how dare you? how disrespectful for you to blame her when she's not even alive to defend herself? >> he grabbed her pony tail and pulled her into the water. that's as simple as it gets. >> there are photographs of plenty of other trainers doing exactly the same thing she was doing. so i knew that seaworld was lying about the fact this was her fault. >> the pony tail in all likelihood is just a tail. the safety spotter who apparently didn't actually see the take down came up with that. >> during the spotter's testimony, osha pushed him to say that he wasn't really sure thought was her pony tail that was in the whale's mouth that, he just saw her underwater and he assumed it was the pony tail. osha contends that the whale came up and grabbed on bransho's

arm. seaworld was saying it was not an aggressive move. one of seaworld's top curators said when dawn was pulled off that ledge, it wasn't necessarily aggressive behavior by the whale. >> the initial grab was not an act of aggression. this is not a crazed animal. >> the industry has a vested interest in spinning these so that the animals continue to appear like cuddly teddy bears that are completely safe. that sell as lot of shamu dolls, a lot of tickets at the gate. and that's the story line that they're going to continue to stick with for as long as they can. >> recognize that those that say this is a crazed animal that

acted out and grabbed dawn maliciously, they want to prove the theorum that captivity makes animals crazy and that is just false. >> all whales in captivity have a bad life. they're all emotionally destroyed. they're all psychologically traumatized. so they are ticking time bombs. it's not just tilikum. >> we have to separate what happened to dawn -- and as tragic as it is, no one wants to see it happen again -- can seaworld create an environment where it never happens again? yes, i absolutely believe they can. >> what if there were no seaworlds? i can't imagine a society with the value we put in marine mammals if those parks didn't exist. >> i'm not at all interested in having my daughter who is 3 1/2, grow up thinking that it's normalized to have these intelligent, highly evolved animals in concrete pools. i don't want her to think that's how we treat the kin that we

find ourselves around on this planet. i think it's atrocious. >> this hearing is expected to last all week with osha continuing to work toward this theory, that seaworld knew there was a calculated risk of injury or death but put trainers in the water with the whales anyway. why seaworld will say that dawn brancheau's death was an isolated incident. but they didn't fit. customer's not happy, i'm not happy. sales go down, i'm not happy. merch comes back, i'm not happy. use ups. they make returns easy. unhappy customer becomes happy customer. then, repeat customer. easy returns, i'm happy. repeat customers, i'm happy. sales go up, i'm happy. i ordered another pair. i'm happy.

there's something wrong, you know, with tilikum, that there's something wrong. and when you have a relationship with the animal and you -- you understand that he's killing not to be a savage, he's not killing because he's just crazy. he's not killing because he doesn't know what he's doing. he's killing because he's frustrated, and he's got aggravations. and he doesn't know how to -- he has no outlet for it. >> now tilikum is spending a

great deal of time by himself and basically floating lifeless in a pool. >> three hours now. and he hasn't moved. >> they try to sugar coat it by saying he comes out in the front pool every once in awhile. now he's doing shows. you know what he does in a show? he does a few bows and he goes back into his little jail cell. that's his life. and i feel sad for tilikum. a regal thing like him swimming around the tank with his fin flopped over like that, compared to a wild bull killer whale that size? one of the most kinetic and dynamic things you can imagine. i feel sad when i see him. >> it's time to stop the shows. it's time to stop forcing animals to perform and basically

a circus environment. they should release the animals that are young enough and healthy enough to be released. animals like tilikum who have put in 25 years in the industry should be released to an open ocean pen so they can live their lives and experience the natural rhythms to the ocean. >> this is a multimillion dollar corporation that makes its money through the exploitation of orcas. >> they're not suitable to have in captivity. >> the whales are really bored. you deprive them of all this environmental stimulation. >> i think that in 50 years we'll look back and go, my god, what a barbaric time.
