Kimberly Jo Dotts, 15, was strung up in a tree and a friend clubbed her to death with a rock for threatening to reveal plans by a group of teenagers to run away to Florida, US police said. "Snitches get hurt," the friend had told the victim, according to witnesses in the town of Clearfield, Pennsylvania. Kimberly Jo Dotts' body was found by walkers on Tuesday in a clearing, known to locals as Gallows Harbour, named after a hanging carried out there in the 19th Century.
