The charges stem from a Jan. 29, 2021, altercation among an imprisoned woman and the correctional officers inside the Rock Island County Jail. The incident was reported to the sheriff's department supervisors, and an internal investigation was ordered on Feb. 2, 2021.

The internal investigation was concluded on Feb. 25, 2021. Rock Island County Sheriff Gerry Bustos said the investigation revealed an isolated incident, though further investigation was necessary.

On March 8, 2021, a criminal investigation was opened and the officers were placed on administrative leave. They were arrested on May 10, 2021, and were terminated by the sheriff's office on May 11, 2021.

The criminal investigation was completed by the Rock Island Police Department and State's Attorney's Office.
