Kerry O’Brien-Krueger was 32 when she disappeared from her Burlington, Wisconsin home. She was last seen December 6, 1989, at the house in the 200 block of North Perkins Boulevard, where she lived with her husband and their young daughter. Her husband, Tracey Krueger, said she left very early that morning for a last-minute business trip to a trade show in Wyoming and later to drive to Chicago with a coworker to catch a flight.

That story unraveled when a coworker called to ask why Kerry had not come to work and it was discovered no trade show or out-of-state travel was scheduled. A neighbor reported an unfamiliar black car outside the Krueger home that morning but saw no one enter it. Kerry’s makeup, identification, and credit cards were left at home. The marriage had been troubled and Kerry had been considering divorce; she also had suffered a severe, unexplained illness for about six months before she vanished.

Tracey Krueger took a polygraph in January 1990 with inconclusive results, canceled a second test citing illness, and later said he had a stroke that caused amnesia for his adult life. He remains a person of interest but no charges have been filed. Does anyone have memories of Kerry, the Krueger household, or that unfamiliar black car in Burlington in December 1989?
