she was missing more than just a leg, says Dr Owiss Koroma, Sierra Leone's only pathologist. On examining her body he found that her tongue, ovaries, intestines, womb, fallopian tube and vagina had also been taken. Someone had removed them with surgical precision. The case, says Koroma, has all the hallmarks of a ritual killing.
These murders, carried out so that body parts can be used in black magic rituals, usually involve child victims, whose younger and healthier organs are thought to be more powerful than those of an adult.
"People use body parts for fame, wealth, or to gain power," says Ibrahim Samura, head of media for Sierra Leone's police force. The parts can be used in different ways, depending on the purpose. Tongues are thought to empower a person to speak well, for example. A juju man will say, "I need a female breast," Samura says. "It will be used as a charm or a sacrifice."

This is in modern day Seria Leone and is apparently done for powerful politicians.
