In the spring of 1979, a young man named Marshall James McMillan, aged 19, vanished from the waters of Lakebay, Washington. On April 9th, while visiting his parents from college, Marshall and some friends decided to enjoy a day on the water. The plan was for Marshall to take his parents' small sailboat to Penrose State Park, while his friends paddled alongside in canoes. However, the weather presented a challenge, and his friends noticed that he was struggling to maneuver the sailboat in the wind. Despite the difficulties, the group of friends paddled ahead, expecting to meet Marshall at their destination. But Marshall and the small sailboat never arrived at Penrose State Park.

Concern grew as time passed with no sign of Marshall. His friends, worried, paddled back to his parents' home, hoping to find him there. When they discovered he hadn't returned, the alarm was raised. The United States Coast Guard was notified and they initiated a search of the area, combing the waters for any sign of the missing college student or his boat. The search brought a grim report from the captain of a fishing vessel who stated he had seen a capsized boat and a person in the water. Tragically, before the captain could reach the individual, they slipped beneath the surface. The sailboat Marshall had been piloting was later found adrift, its location at the time of discovery is not clear.

Despite the extensive search and the somber account from the fishing boat captain, Marshall James McMillan was never found. His disappearance left a void in the lives of his family and friends, a story without a final chapter. The case remains a sorrowful mystery, a young man on a spring outing who was last seen battling the wind in a small sailboat. The official investigation, led by the Pierce County Sheriff's Office, has kept his case open over the decades, a silent testament to a life lost to the unpredictable waters of the Puget Sound. The details of his disappearance, from the hopeful start of a day with friends to the chilling report of a capsized vessel, paint a tragic picture of what was supposed to be a simple, enjoyable outing. The overview of the case is one of a promising young man who vanished in a boating incident, with his remains never recovered, leaving his loved ones with unanswered questions and an enduring sense of loss.
