A suspected rhino poacher was trampled to death by an elephant and his body devoured by lions in South Africa's Kruger National Park, officials said Monday. South African rangers have recovered the skull of the man in the vast Kruger sanctuary, which has born the brunt of much of the country's poaching  crisis. According to a park spokesman, rangers were alerted after the victim's alleged accomplices told his family that he had been crushed to death by an elephant.
