1st trainer killed by Tilikum
Trainer Keltie Byrne was killed at Sealand of the Pacific
The trainer slipped and fell into the pool with the killer whales. Sealand of the Pacific has never had trainers in the water with the orcas, so the orcas didn't know how to respond. Tilikum was one of three killer whales that tossed Keltie back in forth between their mouths. People believe that the orcas were playing. The trainer ended up drowning.
