INFAMOUS: The Horsch House of Horrors

It started with a parked car near Philadelphia's Liberty Bell and a woman's voice from inside: "You're going to hurt me." Within hours, investigators were at the door of a boarded-up rowhouse in the city's Olney neighborhood. What they found inside raised more questions than answers, and months later, they're still trying to separate what's real from what was staged. So our team started digging into the house, the men who lived there, and the women whose trails lead back to it.
