Summary based on the NamUs case record (MP95481) and 4 other sources
In the late summer of 2000, a respected physician from Honolulu, Hawaii, Dr. Eugene Marcel Ambard, vanished without a trace, leaving behind a loving family and a community baffled by his sudden disappearance. On the morning of August 24, the 68-year-old doctor, who worked at the Kaiser Moanalua Medical Center, left his residence in the Hawaii Kai neighborhood. Later that afternoon, at approximately 4:10 p.m., he was seen at a local Foodland grocery store in the same area. This would be the last confirmed sighting of Dr. Ambard. The initial concern for his welfare escalated when his Boston Whaler boat was discovered adrift in the waters off the iconic Diamond Head, its anchor dragging along the ocean floor. This discovery prompted an immediate and extensive search, but tragically, no sign of the doctor was ever found.

At the time of his disappearance, Dr. Ambard was described as a Caucasian male, standing 5 feet 8 inches tall and weighing 170 pounds, with brown hair and brown eyes. The investigation into his disappearance was handled by the Honolulu Police Department, who followed up on various leads and theories, but none led to any definitive answers about his fate. The mysterious circumstances surrounding the discovery of his unmanned boat left many to speculate, but without any evidence, the case grew cold. The Ambard family and the wider community were left to grapple with the painful uncertainty of not knowing what had become of him. For years, his case remained an open and active missing person investigation.

Years after he was last seen, a somber legal conclusion was reached, and in April of 2006, Dr. Eugene Ambard was officially declared deceased. This declaration brought a legal end to his missing person case but did not erase the enduring mystery or the pain of his loss. Dr. Ambard was remembered as a multi-talented individual; beyond his medical career at both The Queen's Medical Center and Kaiser Permanente, he had served as a U.S. Marine test pilot during the Korean War and had also been a teacher at the prestigious Punahou School. He was a skilled yachtsman, a builder of boats and fine koa furniture, and a scuba diver. His disappearance remains a profound loss to those who knew him and a lingering, unsolved case in Honolulu's history, a story without a final chapter, leaving only questions and the memory of a distinguished man who vanished from the island he called home.
