Ambrosio Lizarraga, a 34-year-old Hispanic man, was found dead in a remote area of desert on the outskirts of Las Vegas on the evening of January 10, 2009. He had sustained a fatal gunshot wound to his upper torso.

Responding authorities treated the death as a homicide but were unable to identify any suspects or release descriptions of potential assailants. The investigation yielded no arrests and, over time, went cold, leaving the motive and circumstances of his final hours unresolved.

Does anyone who was in the desert outskirts of Las Vegas around January 10, 2009, or who knew Ambrosio, have information that could help investigators?
