ASHTON, Idaho -- State fish and game officials say they are monitoring a radio-collared grizzly bear that attacked an Idaho Falls hunter near Harriman State Park. Authorities say the victim, Keith Klingler, 38, was bitten in the arm early Sunday when he and two other black bear hunters came across the grizzly. Wardens say one of the hunters fired a shot during the attack, but it's unclear whether the shot hit the predator. Klingler was taken to Madison Memorial Hospital in Rexburg and treated for injuries. The hunters were tracking bears near the Bishop Mountain area of the Harriman State Park. Official say the hunters' hounds tracked a bear, but when the hunters arrived on scene the bear charged, knocking Klingler down. The bear ran off after the shot was fired.
