When a forensic anthropologist named Raymond Chiu began mapping the burial patterns of unidentified remains scattered across a 200-mile stretch of the Texas-Mexico border, he noticed something that border patrol, local sheriffs, and federal investigators had each seen in pieces but never assembled whole: the bodies weren't drifting — they were being placed. Tonight, we follow the five-year obsession that turned a grid of GPS coordinates into the clearest portrait yet of an active killing corridor, and the institutional resistance that nearly buried the evidence alongside the victims.
