Mark A. Nelson, a 55-year-old resident of Potosi, Wisconsin, tragically lost his life in a single-vehicle UTV crash early on December 21, 2025, in Lafayette County.
The accident occurred around 6:30 a.m. on Wildcat Road in the Town of Darlington, where Nelson was driving a 2025 Can-Am UTV eastbound. He failed to negotiate a curve, causing the vehicle to leave the roadway and strike a tree, leading to his partial ejection and fatal injuries at the scene.
Emergency responders from the Lafayette County Sheriff’s Office, Darlington Fire, and EMS arrived promptly after a 911 call reporting the crash with injuries. Nelson, the sole occupant, was not wearing a seatbelt, a factor that contributed to the severity of the outcome in this rural, curved roadway known for challenging driving conditions. The swift response highlighted the coordinated efforts of local agencies in remote areas of southwest Wisconsin.
The Wisconsin Department of Natural Resources Wardens have taken the lead in the ongoing investigation, assisted by the Lafayette County Sheriff’s Office, focusing on factors such as road conditions, speed, and vehicle dynamics common in off-road incidents.
This probe underscores broader concerns about UTV safety in Wisconsin, where such vehicles are popular for recreation but carry risks on uneven or unfamiliar terrain. No foul play is suspected, allowing emphasis on preventive education for operators in Grant and Lafayette Counties.
