Michael Raymond Mark, 47, disappeared on June 3, 1994, while dip net fishing in the Copper River near O'Brian Creek outside Chitina, Alaska. Witnesses reported he accidentally fell into the river, called for help briefly while struggling, and was pulled under by the fast, frigid current and did not resurface.

He is described as a Caucasian male, brown hair and brown eyes, about 5 feet 7 inches and 140 pounds. At the time he vanished he wore Levi jeans, a heavy green outdoor-style shirt, and brown leather boots—clothing that would have become waterlogged and heavy in the turbulent water. An Alaska State Troopers helicopter searched the area but did not locate him.

The river’s swift, glacial waters left no further clues and he was not recovered. If anyone was on or near the Copper River at O'Brian Creek that day or has information about his disappearance, please share what is known.
