2012 Arlington murder arrest 
What we know:
Public records show Mayra Velasquez was arrested on July 16. Velasquez has been charged with capital murder in connection to a Jan. 2012 incident.
She is being held without bond.

Dig deeper:
Arlington Police and the FBI Dallas Field Office will hold a press conference later this week to provide an update on an arrest made in the 2012 murder of 32-year-old Irasema Chavez.
Chavez was found dead at her apartment in the 2700 block of S. Collins Street on Jan. 20, 2012.
2012 surveillance footage
In 2012, Arlington Police released surveillance footage from the night before Chavez’s murder to help identify a person seen entering the apartment, but were unable to identify a suspect in the murder after pursuing multiple leads.
During their investigation, Arlington PD commissioned a generative profile of the suspect, but it did not generate any leads.
In 2024, Arlington PD and the FBI Dallas Field Office partnered on the case by using the FBI’s Investigative Genetic Genealogy program.
In early 2026, detectives made a significant break in the case, leading to an arrest in relation to the case.
What we don’t know:
It’s unclear what the break in the case was that led to the arrest, or the circumstances that led to Chavez’s murder.
What’s next:
Arlington Police and the FBI’s Dallas office will hold a joint press conference at 10:30 a.m. on Wednesday, July 22 to discuss more about the case.
