Final Investigations of Inmate Deaths

McHenry County Sheriff’s Office recently received the final investigations of the in-custody deaths of Sean Grendel, Randy Little, and Timothy Mumford. Each investigation was conducted by the Major Investigation Assistance Team (MIAT) and reviewed by the McHenry County State’s Attorney’s Office. In each of these cases, the State’s Attorney declined to file charges. 

We’d like to extend our gratitude to the State’s Attorney’s Office, McHenry County Coroner, and members of MIAT for their assistance in completing these investigations. 

McHenry County Sheriff’s Office empathizes with members of our community and the families affected by these losses. The Sheriff’s Office is committed to the health and safety of each inmate and is confident in our Corrections Officers’ ability to maintain a safe environment. 

The Sheriff’s Office receives guidance on best practices through the Illinois Department of Corrections (IDOC) standards and American Correctional Association (ACA) accreditation standards. The Sheriff’s Office’s own policies and procedures, as well as the training and professionalism of our Corrections Officers, ensure that these standards are met or exceeded.

In the case of any inmate death, an investigation by an independent agency is always conducted. McHenry County Major Investigation Assistance Team has been called to act as the independent agency in recent events. Details are not released until MIAT, in conjunction with the Coroner’s Office and the State’s Attorney’s Office, concludes the investigation. Information on Colton Sabo’s death is pending the conclusion of the investigation.
