Mr. Marquez, a licensed security guard, was working and driving in the area of the above address (Rushcreek near Ella Boulevard) when he encountered a Ford Explorer SUV.  Marquez was seen inside his security vehicle and approaching the suspect when the suspect fired several shots and then fled on foot.  Witnesses saw the Explorer then flee the scene.  It is believed the suspect was a passenger in the SUV.
