Details of Disappearance

Wolking was last seen leaving his girlfriend's house in the 800 block of 25th Avenue in Rock Island, Illinois at 11:00 p.m. on October 18, 1990. He is known to have arrived at his own home in the 3500 block of 44th Avenue in Moline, Illinois, but what happened after that isn't clear.

His silver and blue 1988 Chevrolet Suburban was later found abandoned in the long-term parking lot of the Quad City International Airport. Authorities determined he had not flown out of the airport.

The vehicle had front-end damage, newspapers and other items were strewn around in the interior and the trailer hitch and wheel wells were packed with mud; Wolking's loved ones said it would be uncharacteristic of him to leave his car in such a dirty condition. There were drops of his blood on all four sides of the car, inside and out. The evidence was analyzed in 2013 and authorities concluded Wolking had been run over by the truck.

Geological testing of the mud on the outside of the car indicated it came from the Poplar Grove  area. A witness came forward to support this, saying they'd seen the truck stuck in the mud behind what is now the Skip-A-Long day care center near Poplar Grove.

Wolking's family noticed before his disappearance that he had been behaving oddly. A few days before his disappearance, at a family birthday party, he paced up and down and seemed preoccupied. He also did not want to stay to deliver the gift. This behavior is uncharacteristic of Wolking.

He told people he was afraid his girlfriend's estranged husband, Cornelius Sedam, was going to kill him, and said if anything happened to him, this man was probably responsible. Sedam had been looking for information on Wolking, had found out his phone number and had called it several times leading up to Wolking's disappearance. After Wolking went missing, Sedam never called the number again. He is considered a suspect in Wolking's disappearance, but he was never charged in the case and he died in 2010 without ever speaking with police on the matter.

Investigators don't believe whoever killed Wolking acted alone. Police have a working theory of a crime: they think he arrived home and was met by one or more attackers near his residence, that a struggle took place and that Wolking was struck by his own vehicle. Investigators believe Wolking's body may be near the Poplar Grove addition in Moline, east of the area now known as Green Valley Sports Complex.

Wolking's body has never been found despite extensive searches.
