Moline police on Tuesday confirmed they are pursuing leads in the missing person case of Jerry Wolking, Sr., a man last seen in 1990.
Mr. Wolking was 52 when he disappeared. Four days after he was reported missing, his 1988 Chevrolet Suburban was found in the parking lot of Quad City International Airport.
Investigators found blood inside and outside the vehicle, which also was muddy and had front-end damage. The car reportedly had not been at the airport the day before, and there was no evidence Mr. Wolking left on a flight.
On Monday and Tuesday, Moline police were at a rural Milan site with a backhoe and endloader. Moline police Lt. John Hitchcock declined to cite the exact location of the search or why it was chosen.
"Detective Mike Griffin put together a bunch of information from all of the things he has studied and through interviews and reports read," Lt. Hitchcock said. "He's done a lot of research. If there's any possible evidence, this might be the place."
Lt. Hitchcock said cadaver dogs from the Madison, Wis., also were on the scene Monday. He said Milan police also are assisting.
"We'll resume what we're doing with the search process as soon as it dries out a little bit," Lt. Hitchcock said.
"We've never closed the case," he added. "It's just Mike (Griffin) has taken an interest, and we've tried to allow him some time to go back and look at some of these cases."
Mr. Wolking's son, Jerry Wolking Jr., said he was aware Moline police were investigating his father's disappearance and that he has been cooperating with authorities.
