Frederick J. Sigo was 22 and a member of the Suquamish Indian Tribe when he was last seen outside his father’s home in Port Orchard, Washington, on November 26, 1986, the day before Thanksgiving. He was with an unidentified white man at that last confirmed sighting and has not been seen or heard from since.

At the time he disappeared Frederick was described as a Native American male with brown hair and brown eyes, 5 feet 5 inches tall and about 130 pounds. The case was reported to the Kitsap County Sheriff’s Office on December 13, 1986. The identity of the man seen with him and other key details remain unknown, and few significant leads or media attention have emerged.

Anyone who knew Frederick, saw him in late November 1986, or has information about the man he was with is asked to contact the Kitsap County Sheriff’s Office.
