On February 24, 2010, Tilikum killed Dawn Brancheau, a 40-year-old trainer. Brancheau was killed following a Dine with Shamu show. The veteran trainer was rubbing Tilikum as part of a post-show routine when the killer whale grabbed her by her ponytail and pulled her into the water.

Who did Tilikum kill first?

Almost to the day of Dawn's death but 19 years earlier, Tilikum claimed his first victim. On Feb. 20, 1991, 20-year-old Keltie Byrne walked into SeaLand of the Pacific in Victoria, British Columbia unaware that she would never walk out again.

Who did Tilikum kill second?

See part one, part two and part three. Daniel Dukes was a troubled individual with a history of petty thefts, marijuana use, and questionable decisions but as a human being, no death is meaningless. Unwittingly, Dukes will forever be remembered as Tilikum's second victim and SeaWorld's first major incident.
