Mark William Allen, a 31-year-old man, was last seen on December 6, 2015, in Livermore, California. Standing at 6'4" and weighing around 260 lbs, Mark had brown hair, blue eyes, and facial hair, which was likely ungroomed. He also had a distinctive scar at the base of his spine. On the day of his disappearance, he was reportedly wearing cargo pants and a sweatshirt. Mark is known to have struggled with mental health issues and often wandered the streets at night. He had a history of disappearing for months but would typically return, which led some to initially believe his absence was voluntary.
Before his disappearance, Mark was possibly living a transient lifestyle and could have frequented shelters or religious facilities in Livermore and other areas such as Pleasanton and Dublin. His case has drawn attention because of his past pattern of leaving for extended periods, though his extended absence this time has caused concern. Mark's whereabouts remain unknown, and he has not been seen or heard from since that December day.
If anyone has information regarding his case, they are encouraged to contact the Livermore Police Department or Cody S Investigations, which is also handling inquiries related to his disappearance. Despite efforts from family and law enforcement, no substantial leads have emerged in this unsolved case.
