They Had the Killer's Blood for 14 Years. Then Came the Breakthrough

In 2012, Irasema Chavez was murdered inside her Arlington, Texas apartment. Investigators had DNA from an unknown woman, surveillance footage, and a crime scene that raised difficult questions—but no name. For more than a decade, the case remained unsolved. Then, in 2026, investigative genetic genealogy gave detectives a new path forward, eventually leading them to someone who had already been connected to the investigation. This video examines the evidence, the original investigation, the breakthrough that came 14 years later, and the questions that still surround Irasema Chavez's death. Mayra Velasquez has been charged with capital murder and maintains her innocence. The allegations discussed in this video have not been proven in court.
