Trash, a drop of blood and genealogy: How Arlington police and FBI made an arrest in a 2012 killing

KERA News · July 23, 2026

Arlington police arrested 42-year-old Mayra Velasquez on July 17 on a capital murder charge in connection with the January 2012 stabbing death of Irasema Chavez, who was found dead in her Arlington apartment with more than 100 stab wounds. A drop of blood collected from the crime scene went unmatched for 14 years until the FBI's Investigative Genetic Genealogy program identified Velasquez through DNA database comparisons in 2026. Velasquez, a Dallas real estate agent, has maintained her innocence through her attorney and remains jailed without bond pending trial.
