Former Deputy Sean Grayson, Convicted in Sonya Massey's Death, Dies in Prison at 32

Sean Grayson, the former Sangamon County, Illinois sheriff's deputy convicted of second-degree murder in the fatal shooting of Sonya Massey, died in prison on August 23, 2026. He was 32. Grayson's trial attorney, Daniel Fultz, confirmed the death to NBC News and CBS News, stating that Grayson died around noon on the Sunday his death was announced. The Guardian
Grayson was six months into a 20-year sentence for second-degree murder, followed by two years of mandatory supervised release under the Illinois Department of Corrections. His death follows a July 2026 denial of medical release by the Illinois prisoner review board. Grayson had been diagnosed with stage three colon cancer in 2023, which had spread to his liver and lungs. By his January sentencing, defense attorney Mark Wykoff said the cancer had progressed to stage 4, spreading to his liver, lungs, and rectum. The Guardian; CBS News
Second-degree murder, under Illinois law, refers to an intentional killing committed under a unreasonable belief that the use of deadly force was justified — distinguishing it from first-degree murder, which requires premeditation. Grayson was convicted of this charge rather than the more serious first-degree count.
The killing that led to Grayson's conviction occurred shortly before 1 a.m. on July 6, 2024. Sonya Massey, 36, had called 911 for help regarding a possible prowler outside her home. During the response, Massey picked up a pot of boiling water from her stove, prompting Grayson to back away, according to court testimony. Grayson testified that he believed Massey was going to throw boiling water on him after she said, "I rebuke you in the name of Jesus." NBC News
Grayson pointed his gun at Massey and threatened to shoot her. She apologized and dropped to the floor, but he fired three times, striking her. First Assistant State's Attorney Mary Beth Rodgers said in court that "I'm sorry" was the last thing Massey said before Grayson shot her. Grayson then declined to offer medical care, according to Sangamon County State's Attorney John Milhiser. Massey was pronounced dead at St. John's Hospital in Springfield. NBC News
The case hinged in part on body camera evidence that captured the shooting and set off protests and calls for justice. Grayson's body camera was not activated for most of the call, only turning on shortly after he pulled his weapon. The evidentiary record also included testimony from Grayson's former partner, Dawson Farley, who said he was not afraid of Massey during the call but instead feared Grayson. Farley testified that he only unholstered his gun because Grayson did. CBS News; NBC News
The shooting prompted policy changes at the state level. Illinois Gov. JB Pritzker signed the Sonya Massey Act, a law requiring stricter background checks for law enforcement hires, which went into effect at the beginning of 2026. Sangamon County officials agreed in early 2025 to pay a $10 million settlement to Massey's family. NBC News
Attorneys Ben Crump and Antonio Romanucci, representing the Massey family, issued a statement in response to Grayson's death saying his death in custody from cancer does not bring Sonya back. CBS News
The broader context here involves the intersection of accountability and prison medical policy. Grayson's conviction and the legislative response it triggered represented one avenue of reform. But his death raises questions about how the Illinois prison system manages terminally ill inmates. The prisoner review board's denial of medical release in July 2026, despite the documented progression of stage 4 cancer, reflects the high bar for compassionate release — a process that allows prisons to free inmates who are gravely ill or near death — even in cases involving severe, end-stage illness. The family's statement draws attention to the tension between institutional accountability and the perceived adequacy of that accountability when the convicted party dies before completing a sentence.
