On the late afternoon of September 17, 2009, the body of a 31-year-old Hispanic man identified as Carlos Valenzuela-Herrera was found in the Las Vegas desert after an anonymous tip led law enforcement to the scene at about 2:52 p.m. Authorities determined his death to be a homicide and investigated possible links to the drug trade, but those leads did not produce a clear breakthrough.

Key facts remain limited: the exact cause of death and the events that brought Valenzuela-Herrera to that remote location are not publicly detailed, no suspects have been identified, and no arrests have been announced. The person who phoned the tip has never been identified.

Does anyone who knew Carlos or who was in that area around mid-September 2009 have information that could help fill in what happened?
