More is being learned about the lives of the 13 brothers and sisters allegedly held captive by their own parents. David and Louise Turpin bought their California home in 2013 for $350,000. Back then, it was a stylish model home for the development with four bedrooms and three baths. Cops say it became a grim and squalid prison for the children. Louise Turpin's sister, Elizabeth Flores, told ‘Good Morning America’ she was creeped out by her brother-in-law.
