A 16-year-old girl was found dead on the beach of Lake Bracciano near Rome by passersby Thursday morning, police said. Officers said that the body of the girl from the nearby town of Anguillara Sabazia showed no signs of violence, but most likely had suffered fractures to one arm, police said. Investigators believe she may have been at a private Halloween party organized in one of the many clubs closed for the winter in the tourist town.
