In a gruesome case that shocked a nation with its brutality, a trained chimpanzee named Travis, who had previously made television appearances, mutilated a woman, Charla Nash, in the home of his owners in Stamford, Conn.
The attack wasn't the first time that Travis showed aggression, but it was undoubtedly the most violent. Nash lost her eyes, hands and most of her face in the attack, forced to undergo many rounds of surgery, including a facial reconstructive procedure.
During the attack, Travis was stabbed by one of his owners in an attempt to pry him off Nash. When officers later arrived on the scene, they shot and killed the ape. Lab tests after the attack showed that Travis's owners had given him tea laced with Xanax in an effort to calm him down earlier that day.
