In the fall of 1986, on the day before Thanksgiving, 22-year-old Frederick J. Sigo, a member of the Suquamish Indian Tribe, was seen outside his father's home in Port Orchard, Washington. He was in the company of an unidentified white male. This would be the last confirmed sighting of Frederick. Since that day, November 26, 1986, he has not been seen or heard from again. At the time of his disappearance, Frederick was described as a Native American male with brown hair and brown eyes, standing at 5'5" and weighing 130 pounds. The circumstances surrounding Frederick's disappearance remain shrouded in mystery, with very little information available to the public or to investigators. The identity of the man he was last seen with has never been established, and no significant leads have emerged in the decades since he vanished. The case was officially reported to the Kitsap County Sheriff's Office on December 13, 1986. Despite the passage of time, law enforcement continues to seek any information that might shed light on what happened to him. The lack of media attention on Frederick's case has made it one of the many long-standing and unresolved missing persons cases in the region. For his family and community, the years have been filled with unanswered questions and the persistent hope for closure. The investigation into Frederick Sigo's disappearance is ongoing, a cold case that serves as a painful reminder of a young man who vanished without a trace, leaving behind a void and a story with no ending.
