Summary based on the NamUs case record (MP107692)
Ricardo Marquez, a 45-year-old man, went missing from Pomona, California, on January 1, 1978. Described as Hispanic with black hair and brown eyes, Marquez was last seen wearing a long-sleeved button-down shirt and blue Levi's jeans. He also had a distinguishing scar on his left cheek and an oval-shaped mole on his left shoulder. Despite efforts from law enforcement and his family, his whereabouts have remained unknown for decades.

The case has garnered limited attention, and details about the circumstances surrounding his disappearance remain unclear. Marquez's profile is listed in national missing persons databases, such as NamUs, where authorities continue to seek information from the public that could help bring closure to his case. Despite the passage of time, the search for answers regarding what happened to him continues, with family and investigators still holding out hope for new leads.

This unsolved case is one of many from the late 1970s in California, a period marked by numerous missing person reports, adding to the complexity of such investigations.
