Matthew Edmond Mattioli was a 60-year-old man from Mineral Point, Missouri, when he was last seen on March 15, 2021. He was male, and public missing-person information described him as a white man with gray hair and hazel eyes, standing about 5 feet 10 inches tall and weighing around 225 pounds. The known public record of his disappearance is limited, but the central fact remained stark: after that March day in Mineral Point, his family and community were left without the answers they needed,
and his name became part of Missouri’s missing-person records while those who loved him waited for word of what had happened.
Matthew’s life was much more than the circumstances of his disappearance. He was born on May 10, 1960, in Lynwood, California, the son of Delores Palmer and Edmond Rudolph Mattioli, and he later made his home in Mineral Point. His obituary described him as a skilled mechanic and talented welder who had worked for nearly 30 years with the same company in St. Louis and was close to retirement around the time of his passing. He married Lisa Rifenburg Mattioli on July 10, 2004, and the two shared 16 years together. He was also a father, grandfather, brother, and friend, remembered as someone who loved his family, enjoyed time with them, and was known by those around him as friendly, smiling, and willing to help others.
The public information about what happened after Matthew vanished is painful and incomplete. A Daily Journal Online report stated that partial human remains found in Washington County were positively identified as Matthew Mattioli, noting that the Mineral Point man had been missing since March of the previous year. The available reporting does not provide a clear, exact public date for when the remains were found, only that they had been found “early last week” in relation to the report, so the precise discovery date remains vague from the online information available. His obituary states that Matthew departed this life on November 13, 2022, at the age of 62 years, 6 months, and 3 days.
With the identification of his remains and the publication of his obituary, Matthew Mattioli’s disappearance is no longer simply an active missing-person matter; it is a resolved case that ended in grief. What began with the disappearance of a 60-year-old man last seen in Mineral Point, Missouri, on March 15, 2021, became a long period of uncertainty for the people who loved him, followed by confirmation that he had died. The available public record does not explain the full circumstances of his disappearance or death, and it does not provide a complete timeline between the day he was last seen and the later identification of remains in Washington County. What it does preserve is the outline of a man’s life and loss: Matthew was a husband, father, grandfather, mechanic, welder, and longtime worker remembered for warmth and helpfulness, and his case stands as a somber story of a family’s search for answers, the eventual identification of their loved one, and the lasting absence left behind.Last Seen: Mar 15, 2021
