One of the other clues to Tilikum’s potential state of mind (Part 1 here) just before he killed Dawn Brancheau is his performance in the “Dine With Shamu” show that she completed with him before he grabbed her.
Trainers working with killer whales are trained to look for clues in their behavior, anything that might indicate that there is something wrong, or potential danger. These are called “precursors,” and no experts I spoke with about Tilikum’s interaction with Dawn in the “Dine With Shamu” show believed that there were any precursors or red flags that should have warned her that she might be in danger. That said, some behavioral experts I spoke with also told me that the “Dine With Shamu” show did not go that well from a performance point of view. Specifically, they said Tilikum appeared uninterested and somewhat disengaged, and did not perform well.
The primary resource when it comes to seeing Tilikum and Dawn’s work together in that show comes from a video made by a family attending the Dine With Shamu show on February 24. Here is the video, made by the Connell family, from New Hampshire. It’s a little difficult to watch, knowing what comes moments after it concludes, but it is a key to helping understand what happened that day.
[Update: WESH-TV, which is a local Orlando station has disabled the embedding for this video. Interestingly, they have not disabled embedding on the other videos on their YouTube channel. SeaWorld conspiracy theorists, you can run with this one! For those who just want to watch the video, click on the link which appears along with the “embedding disabled” message]
To the untrained eye, this looks like Tilikum putting on a pretty good show. And when Dawn engaged with Tilikum after the show, lying down next to him on the slide-out and talking to him and stroking him in what is known as a “relationship session,” it indicated that she thought he had done okay, too, as relationship sessions are partly used as a reward for good behavior (though she also had to keep him engaged while the Dine With Shamu guests headed down to the underwater viewing area).
Following the tragedy, SeaWorld employees described the “Dine With Shamu” show as “perfect,” with nothing out of the ordinary occurring. Here is trainer/spotter Jan Topoleski’s description of the show to Orange County Sheriffs Office investigators:
However, one behavioral specialist I spoke with took the time to break down the video of Dawn working with Tili and found a less than smooth performance.
