In March of 2017, a 36-year-old Navajo woman left her aunt’s house in New Mexico after visiting Arizona, but she never made it to her destination. Five years after she went missing, her former boyfriend was arrested for the murder and dismemberment of at least three people - later saying they were ritualistic sacrifice killings whom he engaged in cannibalism with. This is the story of Tanya Begay, and horrific actions by the Tarrant County Serial Killer.
