Yamada Yoshinyuky, 54, disappeared from the fishing vessel Heather Sea on February 1, 2001, about 300 miles south of Kodiak, Alaska. Crew members reported he had been feeling unwell that day, complaining of sea sickness and headaches before he was later recorded as having fallen overboard. No one witnessed the exact moment he went into the water, and the official report filed with the Alaska State Troopers states he fell overboard.

His family and colleagues were left with unanswered questions after the incident.

Did anyone on the Heather Sea or in the Kodiak fishing community have contact with Yoshinyuky in the days before February 1, 2001?
