PORT HURON, Mich. - Officials are trying to track down the origins of a mummified human skeleton that a Michigan woman tried to sell on eBay. EBay spokeswoman Catherine England said the posting was removed Wednesday because it violated a policy against selling human remains. The Web site allows the sale of skeletons for medical use, but not mummified remains. "There was a bid on it for $500 from `Satans Child," Porrett said.
