On Thursday, October 8, 2026, a Knox County Jail inmate assaulted a female Corrections Deputy while staff were addressing the inmate’s refusal to return to his cell.
The inmate was quickly subdued, and the deputy was transported to OSF St. Mary Medical Center, where she was treated for minor injuries and released.
David Nicholson-Klingerman, age 30, was subsequently charged with Aggravated Battery to a Corrections Officer.
The Knox County Sheriff’s Office remains committed to the safety of its staff and inmates and recognizes the dedication and professionalism of our Corrections Deputies, who face challenging situations daily.
