On September 4th 2006 Australian zookeeper and wildlife expert Steve Irwin was tragically killed while filming an underwater documentary on the Great Barrier Reef. Steve had won global notoriety as the ‘Crocodile Hunter’, handling deadly snakes, toxic reptiles, and apex predators on programmes watched by an estimated worldwide audience of 500 million. But the world was shocked to learn that, at the age of just 44, the seemingly invincible conservationist, had been killed by a creature not known for being aggressive or dangerous – a stingray. Now, world renowned forensic pathologist Dr. Michael Hunter is investigating what led one of the world’s most iconic wildlife experts to be killed by an otherwise docile animal?
