Check the ingredients label on your bar of soap: Three men have been arrested in Peru for killing at least five people and then possibly selling their body fat to European cosmetic and pharmaceutical companies. The men, part of a gang with six other men still at large, were found in the jungle near human remains and two jars of fat. They reportedly drained corpses by severing their heads and limbs then hanging up and heating the bodies in order to let fat drain. There's no actual proof of the fat being sold, though, and experts say that fat for cosmetic procedures is easily available from living patients. "I can't see why there would be a black market for fat," said one professor of plastic surgery.
