Summary based on the NamUs case record (MP14409) and 3 other sources
Mark Thomas Gibson, a 50-year-old man from Jacksonville, Florida, was last seen on the evening of March 12, 2008. On that night, Gibson visited the Flight 747 Liquor Store & Lounge Bar, located on Airport Road in Jacksonville, with a group of friends. His friends left the bar before he did, and Gibson has not been heard from since. His disappearance is considered out of character, leading law enforcement to suspect foul play.

At the time of his disappearance, Gibson stood 5'7" and weighed approximately 130 pounds, with brown hair and brown eyes. There have been very few clues as to what may have happened to him, and despite efforts from both the Jacksonville Sheriff's Office and the wider community, no significant breakthroughs have been reported. His case remains unsolved, and it is categorized as an endangered missing person case.

Gibson's case continues to draw attention due to the mysterious circumstances surrounding his last known whereabouts. Those who knew him insist that his disappearance was unusual, as he was not someone to suddenly go missing without communication. Despite investigations and appeals for information, Gibson’s fate remains a troubling mystery.
