Record producer Christian Julian Irwin wasn't being chased by killers with dogs or by Nigerian Internet scammers, L.A. sheriff's deputies say. After going missing for five days, he was found Friday naked beside a creek in Topanga Canyon, "very delusional. He obviously suffered some mental setbacks." Irwin was taken to a hospital for psychiatric observation. Curious thing: he was found only a quarter-mile from the spot where he called a friend Sunday saying he was being pursued. Is he really good at not being found, or was the army of searchers out looking for him just incredibly unlucky?
