SANTA ANA (AP) — A man who claimed to be Tarzan, climbed a tree and tried to reach the monkey exhibit at an Orange County zoo has been sent to a mental hospital.

John Rodenborn, 37, was ordered into a state facility Thursday after being found mentally unfit to aid in his own defense. He’s facing misdemeanor charges of possessing a controlled substance and improperly entering an animal closure.
