A killer whale attacked and killed a veteran trainer in front of a horrified audience at a SeaWorld Orlando show Wednesday, Feb. 24, 2010. In this photo, the orca Tillikum is seen minutes after the incident. A SeaWorld spokesman said Tilikum was one of three orcas blamed for killing a trainer in 1991 after the woman lost her balance and fell in the pool at Sealand of the Pacific in Victoria, British Columbia. Tilikum was also involved in a 1999 death, when the body of a man who had sneaked by SeaWorld security was found draped over him.
