Detailed Case Breakdown

Kim Michael Klimek Missing Person Case: Wisconsin Man Vanished Before Planned Las Vegas Trip in 1993

Kim Michael Klimek was 43 years old when he disappeared from Wales, Wisconsin, in November 1993. More than three decades later, his whereabouts remain unknown, and Wisconsin authorities continue to list him as a missing person.

Klimek was last known to be in Wales, a community in Waukesha County, on November 7, 1993. What investigators subsequently discovered created an enduring mystery: signs that he had been preparing for a trip to Las Vegas, airline tickets left behind at his residence, and his truck eventually located at an airport — with no record that he ever boarded a flight.

Kim Michael Klimek Last Seen in Wales, Wisconsin

Klimek was 43 when he disappeared. He was described as a white male with blond or strawberry-blond hair and green eyes, approximately 5 feet 11 inches to 6 feet tall and weighing roughly 195 to 205 pounds. He also had a tattoo of an unknown design on his left shoulder.

He operated a business called Perfection Drywall. According to The Charley Project, one of Klimek’s customers eventually reported him missing.

Klimek was last heard from on November 7, 1993. More than a month later, on December 10, deputies were contacted and asked to conduct a welfare check at his residence in the Village of Wales.

The Welfare Check and an Abandoned Trip

When deputies checked Klimek’s home, the residence reportedly appeared to be in order. Klimek was gone, however, and so was his truck.

Investigators found mail in his mailbox dating back to November 8, the day after his last known contact. There were also indications inside the residence that Klimek had been packing for a planned trip to Las Vegas.

But the tickets for that trip were still inside his home.

Authorities subsequently determined that Klimek never made the planned trip. His truck was eventually discovered parked at Mitchell International Airport, now known as Milwaukee Mitchell International Airport. Despite the vehicle being at the airport, investigators found no record indicating that Klimek boarded a flight.

The combination of the tickets left at home, the vehicle at the airport and the absence of a flight record has remained one of the central unexplained elements of his disappearance.

Financial and Gambling Details Reported in the Case

The Charley Project reports that Klimek enjoyed gambling and had previously lost approximately $40,000 while gambling in Las Vegas. The same source states that he reportedly owed approximately $250,000 to the Internal Revenue Service at the time of his disappearance.

Those details provide context investigators may have considered, but publicly available sources do not establish that either the gambling losses or reported tax debt caused Klimek’s disappearance.

Likewise, the discovery of his truck at the airport does not establish that he traveled elsewhere. The Wisconsin Clearinghouse specifically states that Klimek planned a Las Vegas trip but never made it and that investigators found no record of him taking a flight.

Family Never Heard From Him Again

Klimek’s family has said that they believe he would have remained in contact with them if he were able to do so. Wisconsin Missing Persons Advocacy reports that significant events occurred within the family after his disappearance that relatives believed would have prompted Klimek to contact them.

No such contact came.

There has been no publicly confirmed sighting establishing Klimek’s whereabouts after his November 1993 disappearance.

Information Could Still Help Solve the Case

More than three decades have passed since Kim Michael Klimek disappeared, but his case remains publicly listed with Wisconsin authorities.

Anyone who knew Klimek in 1993, encountered him around the time he disappeared, had information about his planned Las Vegas trip, or has knowledge concerning how his truck came to be at Mitchell International Airport is encouraged to contact law enforcement. Even information that appeared insignificant at the time could potentially provide investigators with additional context in a decades-old missing-person case.
