Mountain lion that stalked Ariz. hiker killed Authorities have killed a mountain lion that had stalked a hiker and his dog in a popular recreation area in the Santa Rita Mountains south of Tucson. Coronado National Forest spokeswoman Heidi Schewel said Sunday that the hiker had been walking with his dog on a trail Saturday when he saw the mountain lion following him. She said the hiker shouted and made himself look bigger by waving his arms - "everything that he was supposed to do," Schewel said. When the animal got closer, the hiker fired two warning shots into the air with his gun. When the lion continued to advance, he shot at it, scaring it away. Schewel said the hiker didn't know whether he hit the big cat. U.S. Forest Service officials found the incident troubling because the lion showed no fear of humans....
