Summary based on the NamUs case record (MP88375) and 7 other sources
Scott Andrew Karsten, a 60-year-old man, was last seen in San Clemente, California, on October 24, 2021. He was captured on surveillance footage in the parking lot of a Walmart and a nearby gas station in the early hours of that day. At the time of his disappearance, Karsten left behind his car, wallet, and cellphone, which raised concerns among his family, who reported him missing on October 29, 2021. He was last known to be wearing a blue t-shirt, khaki shorts, and blue sneakers. Karsten has distinctive tattoos, including a Phoenix bird on his upper arm and a lion on his right arm.

Adding to the complexity of the case, Karsten had suffered a traumatic brain injury in the past, which could leave him confused or disoriented. Despite extensive efforts by his family and local law enforcement, there have been few leads in his disappearance, and his whereabouts remain unknown.

Authorities continue to investigate, and anyone with information is urged to contact the Orange County Sheriff's Office.
