On February 20, 1991, University of Victoria marine biology student and part-time trainer Keltie Byrne, 20, slipped and fell into the orca pool at Sealand of the Pacific. She had just finished a show with the three orcas. Since Sealand trainers stay out of the water, she was not wearing a wetsuit. One whale took her in its mouth and began dragging her around the pool, mostly underwater. A champion swimmer who had competed at the international level, she was no match for three huge orcas determined to keep her in the pool. At one point she reached the side and tried to climb out but, as horrified visitors watched from the sidelines, the whales pulled her screaming back into the pool.
"I just heard her scream my name," said trainer Karen McGee, 25, and then I saw she was in the pool with the whales. "I threw the life-ring out to her. She was trying to grab the ring, but the whale, basically, wouldn't let her. To them it was a play session, and she was in the water." McGee and other Sealand staff tried to distract the whales by throwing them fish, banging on the water with steel buckets and giving them hand and voice commands. Nothing worked. Byrne came up screaming one more time and then, as the whale swam round and round the pool with Byrne in its mouth, she finally drowned. It was several hours before her body could be recovered.
She had ten tooth marks on her body, the largest on her left thigh, but was otherwise untouched. The whales had stripped her clothes off. "It was just a tragic accident," Sealand manager Alejandro Bolz told newspaper reporters. "I just cannot explain it."
