Artist renderings of Jane Doe whose decapitated head was found in Western Pennsylvania is shown during a news conference in Economy PennsylvaniaBy Elizabeth Daley ECONOMY, Pa. (Reuters) – Investigators said on Monday that red balls had been placed in the eye sockets of a woman’s embalmed head found a year ago in a case that may be linked to a growing black market for body parts. Economy Borough Police Chief Michael O'Brien at a news conference appealed to the public for help identifying the woman, whose head was discovered in the woods by a child walking home in the rural town about 22 miles (35 km) northwest of Pittsburgh on Dec. 12, 2014. "There's a black market on body parts and that market is pretty extensive," Berosh said.
