Passersby saw the 15-year-old on a Madison, WI street, barefoot, bleeding, and in pajamas.
According to the Associated Press, Mike Vega, who spotted the little girl, said her body was so contorted that he mistook her for an 8-year-old.
Mike called the ambulance and said that during their wait, the little girl told him her stepmother, Melinda Chritton, put her in a basement and she was able to escape through a window.
Authorities said that the victim reported her father, Chad Chritton, also mistreated her, starving her and even forcing her to eat her own feces.
