Summary based on the NamUs case record (MP67264) and 2 other sources
On October 3, 1998, 53-year-old Martin Raymond Coughlin departed from his summer home in Haines, Alaska, embarking on a flight to Seattle, Washington. He was the sole occupant and pilot of his single-engine Beechcraft Bonanza, with the tail number N4479D. At the time of his departure, Mr. Coughlin was described as being 5 feet 9 inches tall, weighing approximately 165 pounds, with blond or strawberry-colored hair and hazel eyes. He was believed to be wearing blue jeans and a t-shirt of an unknown color. His journey began without a filed flight plan, a detail that would later complicate the search for him and his aircraft.

The initial leg of his flight seems to have proceeded without any reported incident. There was a potential sighting of a V-tailed Beechcraft Bonanza, similar to Mr. Coughlin's, at the Petersburg, Alaska, airport around 2:00 PM on the day of his departure. A fuel attendant noted that a single individual exited the plane, which had wingtip tanks and was white in color, but no fuel was purchased, and the plane's identity was never confirmed. After this point, there were no further communications received from Martin Coughlin. Concern for his welfare grew when he failed to arrive at his intended destination. Ten days after he left Haines, on October 13, 1998, his family reported him overdue to the Alaska State Troopers, who then initiated an investigation.

The search for Martin Coughlin and his aircraft was extensive, coordinated by the U.S. Coast Guard and spanning from Alaska through Canada and into the Port Angeles area of Washington. A significant breakthrough in the case came on October 4, 1998, the day after his departure, when a wing-mounted auxiliary fuel tank was discovered floating in the Juan de Fuca Strait, near Chito Beach in Clallam Bay, Washington. It wasn't until after he was reported missing that this finding was connected to his case, with family members positively identifying the tank as belonging to his plane. Tragically, no other parts of the aircraft have been located, and Martin Coughlin has never been found. The prevailing theory held by investigators is that his plane crashed into the strait, and he is presumed to have drowned. The circumstances leading to the crash remain unknown, though weather data from the area on the day of the accident indicated widespread rain showers. The case remains an open missing person investigation, a painful and unresolved chapter for those who knew and loved Martin Coughlin.
