Any updates on this case? Let us know!
Summary based on the NamUs case record (MP57245) and 4 other sources
Mark Leach, a 59-year-old man, went missing on November 9, 2018, in Sacramento, California. At the time of his disappearance, Leach was homeless and regularly received services from the Consultants in Educational & Personal Skills (CEPS). However, after November 9, he stopped attending these services, raising concern about his well-being. He was described as 5'8" tall, weighing about 145 pounds, with gray or partially gray hair. Leach’s case was entered into the National Missing and Unidentified Persons System (NamUs), but there have been no significant updates or leads regarding his whereabouts since his disappearance.

Efforts to locate him are still ongoing, with authorities and services such as the California Department of Justice involved in the investigation. Given his vulnerable situation, the case has been treated as serious, but little is known about what happened to Leach after he was last seen.

The Sacramento Police Department continues to encourage anyone with information to come forward.
