QUINCY (WGEM) - The Adams County Sheriff’s Office confirmed Thursday that officers are working with Illinois State Police and Springfield Police on a homicide investigation. The case involves the body of a man found in a car near where two people were arrested Wednesday in connection with a string of crimes that included carjacking and sexual assault.

Adams County Sheriff’s Office Sgt. Jake McMahon said Bradley S. Yohn, 34, of Springfield, Illinois, and Karen D. Blackledge, 32, of Quincy, were taken into custody about 2 p.m. Wednesday at 1906 Cornell in Springfield. Springfield Police released a statement Wednesday night saying that about the same time, U.S. Marshals made an arrest in an alley in the 1900 block of Cornell.

“While conducting that investigation, they observed a suspicious vehicle in the alley south of Cornell Avenue,” the statement read. “Further inspection of the vehicle revealed a deceased subject inside.”

The release states the investigation is being handled as a homicide, and the identity of the body is being withheld pending an autopsy.

Yohn and Blackledge each face two counts of home invasion, aggravated kidnapping, aggravated vehicular hijacking, residential burglary and aggravated criminal sexual assault. In addition, Yohn was charged with an additional vehicular hijacking that occurred in Adams County last week.

They are in custody in Springfield.

“Currently, we’re just waiting for the manpower to be honest to go over there and get them,” McMahon said. “There is a an ongoing investigation that the Springfield Police Department is conducting in regards to those subjects, but currently they are only being held on are Adams County warrants for their arrest.”

McMahon also said two both vehicles believed to be stolen in the case have been recovered. A blue-green pickup truck was found Thursday on North Bottom Road in Quincy, and a white sedan belonging to the woman police believe who allegedly was assaulted was found in Springfield.

“We’ve still got a lot of foot work to do on our end. Witnesses to talk to, surveillance footage to gather,” McMahon said. “We are still collecting numerous items from throughout the county.”
