Tilikum -- the orca that killed someone at SeaWorld in Orlando 7 years ago -- has died.
The giant mammal died Friday. It's unclear what killed him, but he had been treated for a nagging bacterial infection.
The killer whale -- which was around 36 years old -- killed a trainer back in 2010. He was a central figure in the documentary, "Blackfish," the show which created a backlash against keeping killer whales in captivity.
Tilikum was also involved in 2 other deaths back in the '90s.
RIP
