From this story on abcnews.com:
Utah's elusive mountain man may have inadvertently revealed his identity to two hunters, setting off a massive police operation to snare the man authorities said had roamed a vast mountainous area for six years, allegedly burglarizing and shooting up cabins. After he allegedly fired shots at a police helicopter, pointed his gun at a sheriff and led authorities on a snowshoe chase, 45-year-old Troy James Knapp's run came to an end Tuesday. "He threw his rifle down and told the deputies, 'Good job, you got me," Sevier County Sheriff Nathan Curtis told ABCNews.com. The 50-man operation, involving resources from multiple counties, was put into place after two hunters reported meeting a suspicious man on a narrow trail last Friday. The man did not identify himself, Curtis said, but told them: "I'm a mountain man."
