Tripp Isenhour could be facing charges after an animal rights group called on the PGA Tour to punish him for killing a hawk with a golf shot. The 39-year-old player, whose real name is John Henry Isenhour III, killed the bird after becoming frustrated with its persistent squawking during the filming of his television show Shoot Like A Pro. The incident happened on December 12 at Isenhour's home course, the Grand Cypress Golf Club in Orlando, Florida, and the Humane Society of the United States (HSUS) are now urging the PGA to launch a full investigation. After becoming angry with the red-shouldered hawk, Isenhour is reported to have driven his golf cart to within 300 metres of the bird before he starting to hit shots at it. However, the bird failed to move and the American gave up and drove away.
