Casey Nolan Graham, 24, was last seen in McGrath, Alaska, on December 9, 2015. His Ski-Doo Summit snowmachine was found wrecked beside an open lead of water on the main channel of the Kuskokwim River; Alaska State Troopers located the machine next to a hole in the ice. Search and rescue operations were carried out by troopers, local volunteers and members of his extended community, including former Marine Corps comrades who traveled to assist and support his family.

Initial searches found no indication that Casey had gotten out of the water, and the harsh winter conditions led authorities to a grim presumption about his fate. The discovery of the snowmachine remains the central clue in a disappearance that left family, friends and the community without closure.

If anyone was in the McGrath area on or after December 9, 2015, or has information about activity on the Kuskokwim River that day, please come forward.
