The Illinois Prisoner Review Board has denied a medical release request from Sean Grayson, the former Sangamon County sheriff’s deputy convicted of second-degree murder in the 2024 fatal shooting of Sonya Massey. The board voted unanimously to reject Grayson’s application, a spokesperson confirmed Friday, meaning he will remain incarcerated for the duration of his 20-year sentence.
Grayson, who was diagnosed with Stage 4 colon cancer in 2023, had sought early release under the Joe Coleman Act, which allows for medical release of terminally ill or medically incapacitated inmates. A medical evaluation determined his condition was irreversible and incurable, with doctors estimating he has less than 18 months to live. However, the evaluation did not classify Grayson as medically incapacitated, as his cancer had not yet impaired his ability to perform daily tasks independently.
The board’s decision follows a letter from Sangamon County State’s Attorney John C. Milhiser, who opposed Grayson’s release, arguing that Grayson remains a danger to society. Grayson’s attorney, Mark Wykoff, had previously expressed concerns that prison conditions could worsen his health, noting the cancer had spread to his liver, lungs, and rectum by the time of his sentencing in January 2025.
Key Details of the Case
Grayson was convicted last October of second-degree murder in Massey’s killing. According to court records, Massey called 911 to report a prowler outside her Springfield, Illinois, home in 2024. Grayson, who was dispatched to the scene, entered her apartment and fatally shot her. The incident sparked widespread public attention and legal scrutiny, leading to Grayson’s conviction and sentencing.
Legal and Medical Context
The Joe Coleman Act permits medical release for inmates with terminal illnesses or conditions that prevent them from performing basic daily functions. Grayson’s application cited his terminal cancer diagnosis, but the medical evaluation did not meet the threshold for incapacitation. The board’s decision hinged on the distinction between a terminal diagnosis and the ability to function independently, as well as the state’s attorney’s assessment of public safety risks.
Grayson’s legal team has not indicated whether they plan to appeal the board’s decision. The case remains a focal point in discussions about medical release policies for incarcerated individuals with serious health conditions.
