Summary based on the NamUs case record (MP34269) and 4 other sources
Richard Louis Viglizzo, a 29-year-old man from San Francisco, California, went missing on November 20, 1983. He was last seen in San Francisco and has not been heard from since that day. Viglizzo owned the Viglizzo Family Deli, and his family was also involved in Viglizzo Meats, a well-known local business producing sausages. At the time of his disappearance, Viglizzo was described as 5'7" tall, weighing 150 pounds, with brown hair and brown eyes. On the day he went missing, he was reportedly wearing a black leather jacket, blue jeans, and sneakers.

Despite the passage of decades, very few details have emerged regarding the circumstances of his disappearance. There has been no indication of what might have happened to him, and the case remains unsolved. Viglizzo's family continues to seek answers about what might have occurred, but over the years, no significant leads or evidence have been brought to light.

The San Francisco Police Department is still handling the investigation, and his case remains open. There is dental information available for comparison, but so far, there have been no confirmed discoveries linked to his disappearance. Efforts to find Richard Viglizzo have thus far yielded no results, leaving his case one of many long-term unresolved missing person cases.
