Arthur Eben Hill, Jr., 44, was reported missing from Anderson, Alaska on July 10, 2019 after being dropped off near the Nenana River that morning to go camping. When his campsite was checked later that day his twin-sized air mattress and swim trunks were gone; he was believed to have floated down the river on the air mattress. He was not wearing a life vest and was known not to be able to swim.

Arthur, known also as Art Hill and Smiley Hill, is a white male with blond or strawberry blond hair and blue eyes, about six feet tall and 168 pounds at the time. He has multiple tattoos — religious imagery on his upper right and left arms and left forearm, names on his chest, and additional tattoos on his left leg and shoulder — and scars on his left forearm, left ankle, and left leg. Despite search efforts, no sign of him has been found.

The Alaska State Troopers are handling the investigation and the prevailing theory is a mishap on the Nenana River while floating on the air mattress. Does anyone have information about Arthur’s movements that day or about people who camped that stretch of the Nenana River?
