A dog has sniffed out the scent of human remains at a possible mass grave site where a dad dumped the bodies of dozens of women, police have confirmed.
Lucy Studey, 53, claimed her late father, Donald Dean Studey, who was 75 when he died in 2013, was a serial killer for decades.
She says she was forced, along with her siblings, to move the human remains of women and sex workers across farmland to their house in Iowa.
