Story summary
Sean Grayson, a 32-year-old former Illinois sheriff's deputy, has died while serving his 20-year sentence for the fatal shooting of Sonya Massey, a 36-year-old Black woman. Massey was shot by Grayson in her home in Sangamon County, Illinois after she called 911 to report a prowler on July 6, 2024. The incident was captured on body camera video and sparked protests and calls for justice. Grayson was convicted of second-degree murder last year and had been diagnosed with Stage 3 colon cancer in 2023, which progressed to Stage 4 and spread to his liver, lungs, and rectum.
Grayson's death has left Massey's family feeling robbed of "true justice." Her cousin, Sontae Massey, said that the family was not notified directly about Grayson's death and had to read about it online. The family believes that Grayson should have served his full sentence, even if he was ill. In a statement, Sontae Massey said, "It doesn't feel like justice to me... Sonya should still be here. That is the loss we are still living with."
