A Mystery Killer, Hidden DNA, and the Arrest Police Waited 14 Years For

Episode DescriptionA single drop of blood, a grainy surveillance video, and a 14-year-old mystery have led police to charge a Dallas-area realtor with capital murder. But is that enough to prove who killed Irasema Chavez? This episode examines the latest development in Chavez's 2012 Arlington apartment murder. Investigators found almost no physical evidence at the scene, yet recovered one crucial clue: a fresh drop of blood on the bedroom nightstand. Years later, DNA analysis, genetic genealogy, and a sample recovered from discarded trash allegedly connected the blood to Myra Velasquez, who was arrested and later released on $450,000 bond.You'll hear how surveillance footage captured a hooded figure entering Chavez's apartment shortly before the recording abruptly stopped, why the video has never clearly identified the killer, and how a 2016 genetic composite helped move the investigation forward. The episode also looks at Velasquez's strict bond conditions, her public claim of innocence, and the questions her defense says police still need to answer.The biggest mystery may be motive. Chavez suffered more than 100 stab wounds, and investigators initially described the crime as possibly involving a jealous or scorned lover. At the time, Chavez's relationship had ended that same day, while a 2012 tip alleged that Velasquez's husband was jealous of the friendship between the two women. Could the breakup, jealousy, or another undisclosed relationship explain the violence? With Velasquez now facing a capital murder charge, the case raises a critical question: does the DNA evidence point to the killer, or simply to someone who had previously been inside Chavez's apartment? Listen for the details behind the arrest, the evidence police have not yet released, and the unresolved questions that could shape the case in court.
