On the evening of Christmas Eve 2015 outside the Wild Horse Pass Hotel & Casino in Chandler, Arizona, retired Bakersfield police officer Frank Pascua, 52, was shot and killed after confronting a man who was attempting to steal a car. Calls had come in about a suspicious person with a gun, and Pascua intervened; he was shot multiple times and later died at a nearby hospital.

Investigators detained and then cleared a 25-year-old person of interest early in the inquiry. Attention shifted to 47-year-old John Albert Campos Sr., who was identified as the shooter and described as armed and dangerous. A federal arrest warrant was issued and the Gila River Police Department, with FBI assistance, searched for Campos after he reportedly fled the scene and allegedly hijacked another vehicle; that driver was left unharmed.

Pascua is described as having acted to stop a crime; authorities say the two men did not know each other. Anyone with information about that night or Campos’s whereabouts is asked to come forward.
