The FBI have reportedly joined a police investigation after a woman claimed her dad had killed 'up to 70' women and made her hide the bodies.
Lucy Studey posthumously accused her father Donald Dean Studey last week of slaying the young women over three decades in their hometown of Thurman in Iowa.
Speaking to US news magazine Newsweek, she said Donald had forced her to help move dozens of human remains before they were buried in land surrounding the family home.
