In the summer of 1996, a 33-year-old man named Thomas Leo O'Connor vanished while on a sailing trip in Michigan. On July 12th, he was a passenger on a 1990 Pursuit sailboat, traveling from New Baltimore to Alpena. The waters of Lake Huron turned rough during their journey. It is believed that at some point during the turbulent conditions, approximately 11 miles north of Port Austin, Michigan, Tom fell overboard. At the time of his disappearance, he was described as a White male, 5'7' tall, weighing between 140 and 150 pounds, with brown hair and blue eyes. He was last seen wearing a blue and white shirt, blue shorts, and tennis shoes.
The circumstances surrounding the moment Thomas went into the water remain unclear. The incident was initially reported to the Coast Guard. Two days later, the Huron County Sheriff's Office took a report and opened an investigation into his disappearance. Despite search efforts, Thomas was never located.
The vastness of Lake Huron and the unpredictable nature of its waters presented significant challenges to those searching for him.
Thomas Leo O’Connor was a 33-year-old man when he disappeared in the waters of Lake Huron near Port Austin, Michigan, on July 12, 1996. Known as “Tom,” he had been traveling as a passenger aboard a 1990 Pursuit sailboat registered as MC7699NS. The vessel was making a lengthy northbound journey from New Baltimore, on Lake St. Clair, toward Alpena when the people aboard encountered rough water. At approximately 3:10 p.m., while the sailboat was about 11 miles north of Port Austin, Thomas was apparently no longer aboard. Investigators believe he fell overboard during the difficult conditions, leaving those on the vessel facing the terrifying realization that he had vanished into the open lake.
The available public record contains very little detail about the precise moment Thomas disappeared. It does not explain whether anyone directly witnessed him fall, how much time passed before his absence was noticed, or what immediate attempts were made by the people aboard to locate him. The incident was reported to the United States Coast Guard, and the Huron County Sheriff’s Office took a formal report two days later. The broad stretch of Lake Huron north of Port Austin presented an immense and difficult search area, especially after rough water had already carried the sailboat forward. Currents, waves and the passage of time could have moved a person far from the location where he was last believed to have been aboard.
Thomas was described as a white man standing approximately 5 feet 7 inches tall and weighing between 140 and 150 pounds. He had brown hair and blue eyes. When he disappeared, he was reportedly wearing a blue-and-white shirt, blue shorts and tennis shoes. No distinctive physical feature is listed in the publicly available case information. Those clothing details would have been important during the initial search, but the circumstances offered few fixed points from which rescuers could work. Unlike a disappearance on land, there was no abandoned automobile, residence or roadway to examine for clues. The sailboat and the accounts of those aboard represented the primary sources of information about Thomas’s final known movements.
Publicly available records do not identify any suspect or suggest that another person intentionally caused Thomas to enter the water. No arrest or criminal charge has been reported in connection with his disappearance. The known circumstances instead support the belief that he fell overboard while the vessel was underway in rough conditions. At the same time, the limited public account does not reveal whether he was wearing a life jacket, whether the sailboat was under sail or engine power, or what weather, wind and wave conditions were documented at the time. Those unanswered details leave an incomplete picture of the emergency and of the efforts made to reach him before he was lost from view.
Thomas’s case is recorded in the National Missing and Unidentified Persons System as MP9906 and is investigated by the Huron County Sheriff’s Office under case number 3866-96. A DNA reference sample from his daughter was later completed and entered into the national CODIS system, providing investigators with a means of comparing unidentified remains should a possible match ever be recovered. The existence of that sample reflects the continuing effort to bring certainty to a case in which the lake never returned the person who disappeared. For Thomas’s family, the passage of decades cannot erase the suddenness of a sailing trip that became a permanent separation, or the pain of knowing that his final resting place has never been found. In overview, Thomas Leo O’Connor was a 33-year-old man traveling by sailboat from New Baltimore to Alpena on July 12, 1996, when rough water was encountered approximately 11 miles north of Port Austin; investigators believe he fell overboard into Lake Huron, and despite the reporting of the incident and the continuing documentation of his case, no confirmed trace of him has been recovered.Last Seen: Jul 12, 1996
