Luis Medrano, a 38-year-old Hispanic man, was shot and killed on June 1, 2014, in Houston, Texas. He had been dining with his wife and daughters at Taqueria Cancun in southwest Houston when an argument with another man escalated. Security escorted the other man out, but the confrontation continued in the parking lot where the suspect returned to his car, retrieved a gun, and shot Medrano. Medrano died at the scene.

Houston police investigated and focused on evidence gathering and locating witnesses, but no arrests have been made and the suspect has not been identified. Investigators have not released a detailed description or photo of the shooter, and the case remains open. Anyone who was at Taqueria Cancun that evening or who has information is asked to come forward with tips that could help the family find answers?
