Rosa Elia Barbosa, a 46-year-old Hispanic woman and clerk at a check-cashing business, was murdered at her McKinney, Texas home on March 12, 2004. Three men—Eddie Williams, Javier Cortez, and Raul Cortez—broke in intending to rob her after Javier Cortez had been watching her and believed she took cash home. When no money was found, they forced Rosa to give them the key and alarm code to her workplace; one of the intruders then shot and killed her.

Before they left, Rosa’s nephew Mark Barbosa, 25, arrived with friends Matt Self, 17, and Austin York, 18. The intruders forced the three into a bedroom and shot them. Matt Self was found alive but died at the hospital the next day; Mark and Austin were found dead at the scene by Mark’s brother Robert Barbosa.

The case went unsolved for years until Eddie Williams’s then-girlfriend Talisha Haithcox contacted police and Williams cooperated, and DNA from a cigarette butt linked Raul Cortez to the scene. Raul Cortez was convicted and sentenced to death; Javier Cortez received a federal sentence for weapons charges and Williams received a 20-year term in exchange for testimony. Anyone with information about Rosa or the crime is asked to come forward.
