Michael Shane Chapman, 40, was last seen on Grand Lake near Grove, Oklahoma in late January 2013. A Joplin, Missouri resident, he was known to be on the lake on January 27. His boat was recovered the next afternoon adrift near an area called Sail Boat Bridge with no sign of Chapman on board.

He is described as a White male, 5 feet 9 inches, weighing between 175 and 250 pounds, with long black hair and a long black and gray goatee. He had multiple tattoos: two on his upper chest above the nipple line, tattoos on both arms, and one on his back. When last seen he wore a black hooded sweatshirt, blue jeans, and tennis shoes.

Search teams used helicopters and boats over a 10-square-mile area, but stormy weather hampered efforts. The Grand River Dam Authority Police are handling the investigation. The main piece of physical evidence is the unoccupied boat; because Chapman has not been recovered the case remains unresolved and his fate unconfirmed.

Did anyone who was on Grand Lake that weekend or who remembers seeing an unattended boat near Sail Boat Bridge come forward with information?
