Carlos Alva-Perez was 25 when he was shot and killed on the evening of September 27, 2008, in the 4900 block of Peoria Street in Denver. Police say a vehicle carrying several males and females pulled up alongside his car and a verbal exchange took place. As Alva-Perez tried to drive away, occupants of the other vehicle opened fire, one bullet striking him in the head.

First responders took him to a nearby hospital, where he later died of his wound. The suspects’ vehicle fled the scene. The Denver Police Department continued to investigate, but no arrests have been announced and no suspects have been publicly identified.

Who in the area that night might remember seeing the two vehicles or the people involved?
