Jerry Alfred Wolking, 52, of Moline, Illinois, vanished the night of October 18, 1990, after leaving his girlfriend’s home around 11 p.m. His packed lunch, set alarm and heart medication suggested he returned home that night, but he never reported for work. On October 21 his 1988 Chevrolet Suburban was found in the Quad City International Airport long-term lot with heavy front-end damage, mud on the hitch and wheel wells, trash inside, and drops of blood on all four corners and inside the vehicle. An indentation on the hood was consistent with a person having been struck.

Forensic examination of the mud linked it to the Poplar Grove area of Moline, and Jerry’s wallet was recovered there a week later. Family reported he had been acting unusually in the weeks before his disappearance and said he feared his girlfriend’s estranged husband; that man was later considered a suspect but died without being charged. Investigators believe Jerry was assaulted after arriving home and that his body was removed, but his remains have never been found.

Anyone who knew Jerry, his movements on October 18, 1990, or who can help explain the Suburban’s condition is asked to come forward.
