Robert Cohen Mathis, 54, was last seen June 11, 2011, in Springfield, Florida. He was reportedly dropped off by a friend on Elkcam Boulevard in southern Washington County. Mathis is described as 5 feet 11 inches, about 175 pounds, with gray hair and blue eyes.

On the day he disappeared he reportedly had fishing gear and a firearm with him, which led some to think he might have been preparing for a fishing trip. His daughter and other family members have pushed for answers, but investigators have not turned up significant leads and the case remains unsolved.

If anyone was in the Elkcam Boulevard area on June 11, 2011, or remembers seeing Robert Mathis or a solo angler matching his description that day, please share what was seen or where he might have been headed.
