Susan Kim Mitter, 43, disappeared after falling into the Copper River while dip netting with others on a summer day in August 1990. The outing took place about two miles south of O’Brien Creek in the Chitina area. She was reported to the Alaska State Troopers the same day.

At the time she entered the water she wore blue sweatpants, a black sweatshirt, and black rubber boots. She was 5 feet 1 inch and about 110 pounds, with black hair, brown eyes, a scar on one breast and a scar on her right finger. The Copper River’s cold, glacier-fed waters and powerful currents, plus the remote, steep riverbank, made search efforts difficult and no sign of her has been found.

Does anyone who fished or traveled the Chitina–O’Brien Creek area in August 1990 remember that day or saw anything that could help?
