Florida ? A SeaWorld Orlando trainer attacked by a killer whale died of drowning and blunt-force trauma to her head, neck and torso, an autopsy released Wednesday showed.

The report by the Medical Examiner’s Office ruled Dawn Brancheau’s official cause of death as drowning and traumatic injuries. Her death was ruled an accident, and toxicology tests found no drugs in her system.

The killer whale snatched the 40-year-old trainer from a poolside platform in its jaws and thrashed her around underwater, killing her in front of a horrified audience Feb. 24. It marked the third time the animal, named Tilikum, had been involved in a human death.
