Summary based on the NamUs case record (MP31647) and 2 other sources
Mark William Cowardin, a 51-year-old man, was last seen on June 10, 2013, in Fresno, California. He disappeared under unclear circumstances, and his case remains unsolved. At the time of his disappearance, he was driving a white 2001 Toyota Corolla, which has never been located. Mark was described as 6'0" tall and weighing 180 pounds, with chin-length dirty blonde hair and brown eyes. He had a distinctive star tattoo on his right hand and a scar near his left eye.

Mark had suffered from multiple health issues, including high blood pressure and heart problems, which required medication. Prior to going missing, he had faced hardships, including being mugged while working at a casino in Reno, Nevada, which left him unable to work and eventually led to homelessness. However, he had secured a subsidized apartment in Fresno two years before his disappearance and had been working to stabilize his health.

Authorities have labeled Mark's disappearance as suspicious, and despite efforts, there have been no significant leads regarding his whereabouts. His case continues to be an open investigation, and anyone with information is encouraged to come forward.
