Mark Harrison was 42 when he was last seen in Jacksonville Beach, Florida, on September 20, 2004, during a hurricane. The weather event complicated search efforts from the start, and he has not been heard from since.

Harrison is described as a Caucasian male with brown hair, 5 feet 4 inches tall and about 130 pounds. Few details are available about his movements or who he was with before he disappeared, and the case remains open while authorities and family continue to seek answers.

If anyone was in Jacksonville Beach on or around September 20, 2004, or has information about Mark’s whereabouts that has not been shared with investigators, please come forward.
