Story summary

Sean Grayson, a former Illinois sheriff's deputy, died on Sunday at the age of 32 while serving a 20-year sentence for fatally shooting Sonya Massey, a 36-year-old Black woman, inside her home in Springfield. Grayson was convicted of second-degree murder in October and had been battling Stage 4 colon cancer, which had spread to his liver, lungs, and rectum. He died just six months into his sentence. The shooting occurred on July 6, 2024, after Massey called 911 to report a prowler, and Grayson responded to the call. Body camera video showed that Massey was apologizing moments before Grayson shot her in the face. Massey's family feels that Grayson's death does not bring them justice, as they wanted him to serve his full sentence.
