Ricardo Marquez, a 45-year-old man from Pomona, California, was last seen on July 8, 1977. His disappearance remains an unresolved cold case with little available information about the events leading up to it. Marquez is described as a Hispanic male, standing approximately 5'8" and weighing around 175 pounds, with black hair and brown eyes. He had a linear scar on his left cheek and a distinct oval-shaped mole on his left shoulder. At the time of his disappearance, he was reportedly wearing a long-sleeved button-down shirt and blue Levi jeans.

Marquez's case has seen no significant developments over the years, and it remains an enduring mystery. Despite efforts by law enforcement and missing persons organizations, no substantial leads have emerged that could provide answers to his whereabouts. His case is part of the many unsolved disappearances in California, highlighting the difficulty in solving such long-standing cases.
