Ep 37. The One That Got Out

When authorities found Melissa Ramirez and Claudine Luera murdered and abandoned on the outskirts of Laredo, Texas, they came to a terrifying conclusion over the similarities between the two crime scenes: the city's red-light district had become the hunting ground of a serial killer. How many more women would become victims? In a new "20/20," ABC News correspondent John Quiñones reports on the investigation that ultimately led to one of their own, border patrol supervisor Juan David Ortiz, who was assisting on the case. "20/20" also examines key witness testimony and police body camera video, as well as unpacks Ortiz's nearly nine-hour interrogation that led to his shocking confession.
