Ernie Lopez, Released

"You hear the door open and they say, 'Lopez. You're going home.'" Ernie Lopez walks out of prison to greet family, friends and reporters after a Texas court threw out his 2003 conviction of sexually assaulting 6-month-old Isis Vas. Joint reporting from FRONTLINE, ProPublica and NPR in "The Child Cases" raised questions about the evidence used against him.
