GALESBURG — The identity of the body found Oct. 7 in a storage unit in Maquon could remain unknown for several more weeks after a lab was unable to find any “usable” samples from the body to match its DNA with possible family members, Detective Sgt. Brad Davis of the Knox County Sheriff’s Department said.

Davis said a forensic pathologist will now conduct several other different tests to try to confirm the identity of the decomposed body found after people complained to police of an odor coming from the storage facility. Davis said he does not have a “time frame at this point” but estimated results from those tests could take several more weeks.

“There just wasn't a usable sample from what we had,” Davis said. “We were hoping there was something they could use but there wasn't.” 

The Peoria County Coroner’s office conducted the autopsy of the body. Davis said the samples were sent from the Peoria coroner's office to a private lab and the private lab determined there was no usable DNA in the samples.

Mark Thomas, Knox County’s coroner, said information from the body’s autopsy, such as the cause of death, is not available because the case is still an open investigation.

There's no indication yet how long the body was in the storage unit. The remains were discovered Oct. 7 after Knox County Sheriff's deputies responded to a complaint about a smell coming from Roberts Self-Storage facility, 105 E 3rd St. in Maquon.

Mary Oglesby was arrested Oct. 11 and charged with one count of concealment of a death, a Class 4 felony, by Knox County State’s Attorney Jeremy Karlin in connection to the human remains found in the storage unit.

Oglesby, 50, lived across the street from the storage unit facility. Online records show she remains in custody in the Knox County Jail. 

Court records show that on Oct. 17 she was charged with two counts of forgery and two counts of possession of firearms without a requisite FOID card, all Class 3 felonies, by Knox County Assistant State’s Attorney Ashley Worby.

The charges state that on two separate occasions in May 2022 Oglesby knowingly possessed firearms belonging to the deceased individual and delivered to a buyer a bill of sale for the firearms that was purported to have been made by another person.

The new charges were cited in a decision Judge Richard Gambrell made Nov. 1 to increase Oglesby’s bond from $10,000 to $100,000. 

Court records show that Oglesby has maintained her plea of not guilty.
