Mario Rodriguez Hernandez, a 68-year-old door-to-door jewelry salesman who used a cane after prior strokes, was last seen March 17, 2005, leaving his home in the Town and Country Village mobile home park in Santa Ana, California around 8 a.m. He told family he was going to a scheduled appointment to sell jewelry and would be back before lunch but did not return, answer calls, or attend a planned dinner.

A week after he vanished, Hernandez’s van was located abandoned in Mission Viejo with a strong smell of gasoline inside; there were no immediate signs of foul play reported at that scene. Investigators later traced a large amount of Hernandez’s jewelry to a client, Rebeca Diaz-Nivarez, who pawned it shortly after his disappearance. Diaz-Nivarez and her son, Ricardo, were charged, convicted and sentenced to 25 years to life for Hernandez’s murder, but his body has never been found and the case remains open.

Did anyone in Santa Ana or Mission Viejo see Hernandez the morning of March 17, 2005, or recall unusual activity around the Town and Country Village mobile home park that day?
