DNA-Guided Breakthrough Lands Suspect in 2012 Arlington Murder
Arlington police and the FBI arrested Mayra Velasquez for capital murder in the 2012 stabbing death of Irasema Chavez after investigators used investigative genetic genealogy to connect a DNA sample from the scene to Velasquez. A discarded-trash DNA sample matched Velasquez, leading to the arrest in Hurst; the motive remains unclear, and Velasquez is being held without bond.
