An Illinois Prisoner Review Board has denied a request for medical release for Sean Grayson, a former sheriff’s deputy convicted in the 2024 killing of Sonya Massey in her home in Springfield. State officials said the board’s decision was issued after review of Grayson’s medical situation and his sentence. NBC News and The Guardian report that Grayson has been diagnosed with colon cancer. According to The Guardian, his attorney previously stated in January that the cancer had progressed to his liver and lungs. Grayson was sentenced to 20 years in prison for fatally shooting Massey after she called 911 regarding a possible prowler. The denial means Grayson remains in custody rather than being released early on medical grounds. The reports do not indicate any alternative release arrangement or changes to his existing sentence following the board’s decision.
