Killer Girlfriend Kills Her Friend _ Doesn_t Realize She Left DNA Evidence

A quiet apartment in Arlington, Texas, became a scene of unimaginable violence in 2012 when 22‑year‑old Irasema Chavez was found stabbed more than 100 times[reference:0]. For over a decade, the case remained cold — until a single quarter‑sized drop of blood, left behind at the crime scene, told the story police had been waiting to hear[reference:1][reference:2]. Investigative genetic genealogy led detectives to Mayra Velasquez, a 42‑year‑old real estate agent and a close friend of the victim[reference:3][reference:4]. Prosecutors allege that jealousy over the two women's relationship may have been the motive[reference:5]. Velasquez, who has maintained her innocence, now awaits trial for capital murder, her freedom held by a $450,000 bond and a GPS monitor[reference:6][reference:7]. This is the chilling story of a friendship that ended in a bloodstained betrayal.
