Michael Paul Williams, a 30-year-old American Indian / Alaska Native man from the remote Yukon River village of Kotlik, was last seen on October 2, 1988. He was wearing a maroon or red nylon windbreaker, a gray hooded sweater, green camouflage army pants, white tennis shoes and glasses. Troopers were not notified until October 5, 1988, when the Alaska State Troopers opened an investigation.

Reports note that Michael was believed to have been carrying a significant amount of money when he disappeared. The sparse population and isolation of Kotlik in the Kusilvak Census Area produced few leads, and the case grew cold over the years. A NamUs missing person record for Michael was created on May 1, 2014. The investigation remains open with the Alaska State Troopers.

If anyone in Kotlik or the surrounding region remembers Michael, his movements that week, or saw someone matching his description on October 2, 1988, please come forward with any information.
