Derek J. Partridge was 47 years old when he was last known to have contact in Carmel, Maine, in Penobscot County, on November 13, 2015. Public missing-person records describe him as a White/Caucasian man with brown hair and brown eyes, standing about 5 feet 8 inches to 5 feet 10 inches tall and weighing around 230 pounds. He sometimes had a goatee, and one of his most identifiable physical features was a large dragon tattoo on his left forearm.
When last seen, he was reported to be wearing blue jeans and a sweatshirt, and he was carrying a backpack. Records also note that he had taken off his watch and wedding band before he went missing.
The available public account of Derek’s disappearance begins with a troubling change in routine. According to NamUs-based case summaries, he had quit his job and then sent a text message to a family member, or in some accounts specifically to his wife, explaining where his truck could be found. That message became one of the clearest pieces of information left behind. Four days later, on November 17, 2015, his vehicle was located in the Walmart parking lot in Palmyra, Maine. The discovery of the truck shifted attention from Carmel to Palmyra, where investigators had a more specific place to trace his last known movements.
Surveillance footage reportedly showed Derek parking his truck at the Palmyra Walmart and then walking away toward Route 2. After that moment, the public trail goes quiet. The case summaries consistently state that he has not been seen or heard from since. There is no public indication in the sources reviewed that he returned home, contacted family, or was located after walking away from the parking lot. The details that remain are sparse but deeply significant: a parked truck, a text about where to find it, a man carrying a backpack, and footage of him walking toward a road from which no confirmed public sighting has followed.
Derek’s case is listed in NamUs as MP32709, and the investigating agency is Maine State Police Troop E in Bangor. The agency case number listed in the provided public case data is SP15-104492, with the report date recorded as November 17, 2015, the same date his truck was found. Maine State Police notes that its online missing-person list is not a complete list of all missing people in Maine and directs the public to NamUs, which the state’s Office of Chief Medical Examiner uses to help track and manage missing-person case files. NamUs itself describes the system as a national repository for missing, unidentified, and unclaimed persons cases.
The public facts leave Derek Partridge’s disappearance as a painful and unresolved story centered on a brief sequence of known events in mid-November 2015. He was last seen in Carmel, left information about where his truck could be found, and the truck was later located at the Walmart in Palmyra. Surveillance then placed him walking toward Route 2, after which the confirmed public record ends. In overview, Derek was a 47-year-old man from Maine whose final known movements suggest he intentionally separated from his vehicle, but the available sources do not explain where he went afterward or what happened to him; his case remains defined by the unanswered space between the parking lot in Palmyra and the absence that followed.Last Seen: Nov 13, 2015
