John Thomas Wallenkamp, 62, was last seen on October 27, 2021, in the Town of Arena near Blue Mounds, Wisconsin. He is a white male, 5 feet 10 inches and about 200 pounds, with red or auburn hair and hazel eyes. His vehicle was found parked at his home, which led investigators to conclude he likely left on foot; what he was wearing that day is unknown.

The Iowa County Sheriff’s Office was notified two days after he was last seen. A coordinated search followed, involving Iowa County Emergency Management, local fire and EMS teams, K-9 units, drones and ground crews working the densely wooded terrain of the Town of Blue Mounds. An Endangered Missing Person Alert was issued in November 2021 and flyers with his photo and description were widely distributed; local media covered the case and residents were asked to check properties, outbuildings and trail cameras.

The active search phase later shifted to an ongoing investigation. Little is known about the events before his disappearance, and investigators continue to ask the public for any information, no matter how small, that might help locate him. If anyone knew John Wallenkamp, saw him on or after October 27, 2021, or noticed anything unusual in the Blue Mounds area, please come forward with what was seen.
