Parts of a mutilated body have washed up on the sands of Copacabana beach in Rio de Janeiro just meters from where beach volleyball athletes will compete in the upcoming Olympics. The discovery is the latest to unnerve the city as it grapples with rising crime, a recession and exhausted state finances at a time when it hoped to be celebrating the first Olympics ever held in South America. It was unclear Wednesday afternoon what conditions may have led to the mutilated body but a policeman standing guard by a security perimeter confirmed its existence to Reuters.
