Terrifying footage has resurfaced showing the moment a trainer was mauled to death by a grizzly bear after a 'simple routine' went horribly wrong back in 2008.
Trainer Stephan Miller tragically passed away after the bear, known as Rocky, suddenly attacked Miller after becoming disorientated while filming a promotional video at the Predators in Action facility in West Virginia.
Rocky then tried to bite his trainer on the neck and forcibly pushed him to the ground as distraught onlookers rushed to the scene to try and help distract the bear.
