By the time anyone reported her missing, no one had seen 13-year-old Erica Parsons for 20 months. For years, her adoptive parents abused her, then led officers on a twisting path of lies before finally pleading guilty to her murder. For the first time, investigators in the case are opening their files – sharing video, photos and information not made public before now. WSOC’s Allison Latos gained unprecedented access and shares Erica’s life story, along with ways to help other children still in danger.
