Surveillance video and DNA composites from Irasema Chavez's cold case
Surveillance video shows Irasema Chavez's killer arriving at her Arlington apartment on the night of Jan. 19, 2012. A minute passes before Chavez opens the door and lets the visitor in. Other evidence found at the scene would later reveal that the visitor was a woman.
Composites, created by Parabon Nanolabs, predict the physical appearance of Irasema Chavez's killer based on DNA left behind at the crime scene.
