Kristopher Paul Gregory, 27, was last seen on December 7, 2017, in the remote village of Sleetmute, Alaska. A Native American man with black hair and brown eyes, he was reportedly wearing all black clothing, including black Carhartts. He was attempting to cross the icy Kuskokwim River on a snowmachine when he disappeared.

Authorities believe he likely fell into the frigid water and drowned, but his body has never been recovered. The Alaska State Troopers classify the case as Lost/Injured Missing and have kept the investigation open; searches have not produced physical evidence or witnesses. The exact sequence of events that day remains unknown, leaving his family without closure.

Anyone with information about Kristopher’s last movements or the river crossing is asked to contact the Alaska State Troopers.
