Testimony by an Illinois State Police special agent during a preliminary hearing on Wednesday, May 20, revealed the brutality of Kimberly Mattingly’s death in early April north of Beecher City.


Special Agent Windy Westfall testified in Effingham County Circuit Court during the joint preliminary hearing for Christopher Glass and Aaron Kaiser, Effingham County residents accused in Mattingly’s murder and burying her body to conceal the crime. The shooting occurred on April 6.


Agent Westfall referred to interviews of the defendants she witnessed in late April where both men admitted to their roles in the killing. Westfall, who was questioned by Effingham County State’s Attorney Bryan Kibler, referred to the victim’s autopsy she attended that confirmed Mattingly suffered six gunshot wounds. Her body was then dragged on a tarp down a hill for burial in a pit. When investigators unearthed the shallow grave, it had filled with water due to heavy rainfall. The secret burial was on property owned by Kaiser’s parents, where the defendant lived.


Westfall explained Illinois State Police Region 5 investigators became involved in the case due to a missing person report filed by Mattingly’s relatives with the Shelby County Sheriff’s Department. Mattingly went missing after April 5 and the report was filed on April 8, tragically two days after the murder occurred. Relatives suspected something might have happened to the 29-year-old mother with children.


Different information and leads produced interviews with Glass, a 36-year-old resident of Mason, and Kasier, 37, of rural Beecher City. ISP investigators Sgt. Zach Nichols and Kyle Border of Zone 5 Investigations were involved in the interviews detailed by Westfall.


After Westfall’s testimony, Judge Alan Lolie found probably cause for the counts of first-degree murder and concealment of a death against Glass, and a count of concealment of Mattingly’s death against Kaiser. Those charges were filed were read in circuit court to the defendants on May 1 with both defendants in custody. Glass was arrested in Terre Haute by city and state officers there.


Lolie rejected a request from Lucas Mette, Kaiser’s attorney, to have his bond lowered from $750,000 due to his past record and his classification as a possible flight risk. Bond is set for $5 million for Glass. For release on bail, the defendants must pay 10 percent of the bond amount.


Both defendants, both shackled and wearing face masks, were returned to their cells after they were present for the hearing through a closed-circuit television connection to Effingham County Jail – a procedure common with most criminal cases this spring due to coronavirus safety measures.


Public Defender Scott Schmidt and Mette, offered not guilty to the charges for their clients and a tentative jury trial date was set for August 24 in Effingham County, pending any future motions that could push back the trial date. There will be separate trials for Glass and Kaiser; the preliminary hearing was held jointly last week.
