On September 19, 1993, 28-year-old Clarence W. Brush, Jr. was in a skiff on the Yukon River near Nulato, Alaska, when the small boat overturned about one mile from the village. His companion was carried downstream and rescued, but Clarence was last seen fighting the current and swimming toward shore. The skiff was later found, but Clarence was never located.

At the time he disappeared he was wearing a brown Carhartt bib, a green U.S. Army shirt, and Army combat boots; neither man had been wearing life vests. The Alaska State Troopers classify the incident as not suspicious and list him as a missing person. Extensive search efforts were conducted but did not recover him.

If anyone in or around Nulato at the time remembers the river conditions that day or saw the skiff, any information could help the Brush family and investigators.
