They've been searching for almost seven days.
On Sunday Slappey was sucked over a spillway at the Jim Woodruff Dam while duck hunting on Lake Seminole.
Law officers and volunteer crews from several different Florida and Alabama agencies scanned the Apalachicola River for Slappey's body.
Because the water is so cold and turbulent they expect the search to go on another couple of days.
A celebration of life service scheduled for Slappey Saturday afternoon at the First Methodist Church of Albany.
