Different victim. The victim being talked about having no relatives to report her missing was the woman abducted from the car and killed with the anthrax. The one who's ashes were scattered was the blonde from the basement.
Agh... see i was confused thinking that the blonde hadnt been reported missing either.
Blonde = ELizabeth
Brunette = Peta's sister
Woman in car = Peta who had no one to report her.
