Glenn Barry Patterson was 30 years old when he was last known to be at Schoodic Lake in Piscataquis County, Maine, on September 30, 1989. He was a White/Caucasian man with brown hair and brown eyes, listed at about 5 feet 9 inches to 5 feet 10 inches tall and approximately 155 to 165 pounds. His identifying features included a small mole on the right side of his nose and a small scar at the outside corner of his right eye. At the time he disappeared, he was reported to have been wearing work boots, jeans, a shirt, and a red-and-black checkered jacket, and he was believed to have had a bone-handled jackknife in a holder and his wallet with him. NamUs lists him as Missing Person case MP54341, with Schoodic Lake as the place of last contact.
That day, Glenn went out onto Schoodic Lake with his friend Jeffrey Hall, who is separately listed as NamUs missing person MP54352.
The trip took place on the final day of fishing season, a detail that gives the day a quiet, ordinary purpose before it became a lasting tragedy for two families. Schoodic Lake itself is a large, deep body of water in Piscataquis County; Lakes of Maine lists it at 7,021 acres, with 32.5 miles of perimeter, a mean depth of 79 feet, and a maximum depth of 188 feet. It is a coldwater fishery, the kind of place where an end-of-season fishing trip would have made sense, but also a place where sudden trouble on the water could become difficult to resolve quickly.
The known public account of the disappearance is brief and painful. Glenn and Jeffrey went out fishing together and did not return. Their boat and various items were later found on the lake, but the two men were gone. In Jeffrey Hall’s companion case summary, the account adds that they failed to return that night and that the next day their boat was found in the lake, partially submerged. These details suggest that whatever happened unfolded on or near the water, leaving behind the vessel and belongings but no clear explanation for where Glenn and Jeffrey went or what final moments led to their disappearance.
The case has remained publicly spare, with no detailed timeline, witness account, or confirmed recovery information available in the sources reviewed. The Maine Warden Service is listed in the case data as the investigating agency, and the case was reported on the same date Glenn was last known to have contact, September 30, 1989. The available NamUs-related information also reflects that DNA reference information exists in connection with the case, including a completed maternal sample and a pending son’s sample, a reminder that even many years later, family connections remain central to the effort to identify, compare, and resolve missing person cases when possible.
For the people who loved Glenn Patterson, the known story is not only about a missing boat or a lake search; it is about a man who left for a familiar outdoor activity with a friend and never came home. He was last seen at Schoodic Lake, Maine, on September 30, 1989, while on a fishing outing with Jeffrey Hall. Their boat and belongings were found, but both men remained missing, and public sources do not provide a confirmed resolution. The case overview is that Glenn Barry Patterson, age 30, disappeared from Schoodic Lake in Piscataquis County during a final-day-of-fishing-season trip with Jeffrey Hall; the boat was later located partially submerged with items left behind, no confirmed recovery has been publicly documented in the reviewed sources, and the disappearance remains remembered through NamUs case MP54341 and the continuing hope that the unanswered questions surrounding that day may one day be resolved.Last Seen: Sep 30, 1989
