Heather Leigh Cook, 37, was last seen October 18, 1992, aboard the Sea Note, a 35-foot sea cucumber and urchin dive boat that reportedly rolled and sank just outside Yakutat, Alaska. Both Cook and the other crew member vanished into the Gulf of Alaska; neither body was recovered. Debris from the vessel washed up along a five-mile stretch of beach near the Awke River, confirming the Sea Note had been lost.

The Alaska State Troopers opened a case on October 20, 1992, and the official investigation concluded Heather was lost at sea after the vessel sank. Without recovered remains, the full circumstances of what happened aboard the Sea Note remain unknown.

Did anyone in the Yakutat area in October 1992 witness the Sea Note before it sank or remember details about the crew that could shed light on what happened?
