Christopher Michael Dew, 29, was shot and killed by Irving, Texas police officers on January 29, 2016, after attempting to rob a check-cashing store on Esters Road. During the robbery he took a female employee hostage and led her into the parking lot while holding her at gunpoint. Officers on scene ordered him to drop the weapon; he refused and was shot. The hostage was unharmed.

Irving police detectives, internal affairs and the Dallas County district attorney’s public integrity unit investigated whether deadly force was justified. Investigators found no evidence linking Dew to other burglaries in the Dallas–Fort Worth area, treated the robbery as an isolated incident and concluded the officers acted in self-defense and in defense of the hostage. No arrests or other suspects were identified in connection with the shooting.
