Dwayne Daniel Vanvleet was a 41-year-old male who was last seen on May 4, 2024, in Waupun, Wisconsin, a Dodge County community near the Horicon Marsh. Public missing-person listings identified him as Dwayne Vanvleet, case number MP126138, and described him as 6 feet 1 inch tall and about 210 pounds, with brown hair and hazel eyes. His race and ethnicity were listed as uncertain in public case summaries, and the available public details did not describe what he was wearing or whether he had any
known distinctive physical features at the time he was last seen.
The central circumstance in the case was the discovery of his vehicle in a remote part of Horicon State Marsh. According to the case data, the vehicle was found with his keys, wallet, and phone still inside, a detail that would have deepened concern because those are the items many people rely on to move through daily life, identify themselves, communicate, and return home. Horicon Marsh itself is not a small or simple place to search; official wildlife sources describe it as a vast wetland of more than 33,000 acres, with the southern third managed by the Wisconsin Department of Natural Resources as Horicon Marsh State Wildlife Area and the northern two-thirds managed as Horicon National Wildlife Refuge.
The case was listed through NamUs as Missing Person case MP126138, with Michigan State Police identified in the provided case data as the investigating agency and with the Dodge County Sheriff’s Office also named as an agency to contact if Dwayne was located. The involvement of Michigan State Police, specifically the Jackson Post, suggests that the case was not viewed only through the place where his vehicle was found, but also through law-enforcement connections beyond Wisconsin. The publicly available missing-person summaries repeated the same core facts: Dwayne was 41, male, last seen in Waupun on May 4, 2024, and physically described as 6 feet 1 inch, 210 pounds, with brown hair and hazel eyes.
The available case data now lists Dwayne’s case resolution status as Deceased, meaning this is no longer an active missing-person case and that he was regrettably located deceased. The exact date of that recovery is not clear from the available information, so the public record, as provided, remains vague on when that final development occurred. What is clear is that the case began with a man last known to be in Waupun, moved into urgent concern after his vehicle was found in the remote marsh with essential personal belongings left behind, and ultimately ended in the confirmation that Dwayne Daniel Vanvleet did not survive. In overview, this was the case of a 41-year-old man whose disappearance on May 4, 2024, led investigators and the public to focus on the Horicon Marsh area, where his vehicle and personal effects were found, before the case was later closed after he was located deceased.Last Seen: May 4, 2024
