Sean Grayson, the former Sangamon County, Illinois, sheriff’s deputy now facing murder charges in the death of Sonya Massey, left a previous agency following allegations of inappropriate conduct with a female detainee. Grayson was also accused of retaliating against the detainee’s boyfriend after she filed a complaint.
Invisible Institute, Illinois Public Media, and the Investigative Reporting Workshop obtained new records from the Logan County Sheriff’s Office, where Grayson worked for 11 months prior to Sangamon County, that show department officials concluded Grayson ignored internal policies during a high-speed chase, fielded at least two formal complaints about his behavior, and told him directly that they had considered firing him.
These records also include audio recordings from a November 2022 interview between Grayson and Logan County’s chief deputy which suggest the department — as well as other police departments that had employed him — were previously aware of issues with his performance and integrity as an officer.
Grayson’s relatively short law enforcement career, during which he moved between six Central Illinois police departments in just four years, has come under scrutiny in the weeks since he shot and killed Sonya Massey on July 6, 2024. Body-camera footage of the incident shows that Grayson shot at Massey three times after entering her home and telling her to drop a pot of boiling water. He has since pleaded not guilty to charges of first-degree murder, aggravated battery with a firearm, and official misconduct.
