Mark Deon Giddens was 41 and working as a fisherman in East Baton Rouge Parish, Louisiana, in the summer of 2010. Friends and family last heard from him by phone on July 1, 2010, when he said he was in Louisiana and planned to travel to Florida, possibly circumnavigating the U.S. coast by canoe or another small boat. After that call he vanished from contact.

He is described as a white male with red or auburn hair, blue eyes, fair freckled skin, pierced ear and a small homemade tattoo on an upper arm. Height is listed between 6 feet 0 inches and 6 feet 3 inches, weight 140 to 170 pounds. He typically dressed casually in t-shirts, plaid long-sleeved shirts, jeans or cut-off jeans, steel-toed boots and a watch.

The circumstances of his disappearance are unclear. If anyone knew Mark, his travel plans, or saw him after July 1, 2010, please come forward with information.
