Sean Grayson, the former Sangamon County, Illinois, sheriff's deputy convicted of second-degree murder in the 2024 fatal shooting of Sonya Massey, has died roughly six months into a 20-year prison sentence. His attorney Daniel Fultz confirmed the death, though the cause has not been officially linked to the Stage 4 colon cancer Grayson was diagnosed with before the killing.
A police deputy in Illinois shot and killed a woman named Sonya Massey in her home in 2024 after she called 911 for help. He was found guilty of murder and sent to prison for 20 years, but he died this week while still serving his sentence. His lawyers said he was very sick with cancer, but it's not yet confirmed that's why he died.
Analysis
Daniel Fultz and the question of cause
Grayson's defense attorney Daniel Fultz told NBC News his client died around noon on Sunday, roughly seven months after being sentenced in January to 20 years in prison for second-degree murder. The article does not definitively attribute the death to cancer, noting only that Grayson had been diagnosed with Stage 3 colon cancer in 2023, which another defense attorney, Mark Wykoff, said at sentencing had progressed to Stage 4 and spread to his liver, lungs and rectum. In July, the Illinois Prisoner Review Board denied Grayson medical release, a decision that becomes freshly relevant in hindsight given his death less than a month later. The Illinois Department of Corrections or the county medical examiner would typically be the parties to issue an official cause of death, and the article flags that this confirmation was not immediately available.
$10 million settlement and the Sonya Massey Act
Massey's killing in the early hours of July 6, 2024, after she called 911 to report a prowler, became a national story both because of the body camera footage showing the encounter and because of the policy response that followed. In early 2025, Sangamon County agreed to pay a $10 million settlement to Massey's family, one of the larger pre-trial payouts in an Illinois police shooting case in recent years. Illinois Governor JB Pritzker then signed the Sonya Massey Act, a law requiring stricter background checks for law enforcement hires, which took effect at the beginning of this year. The legislation is the most concrete legislative legacy of the case, though its enforcement and impact on hiring practices across the state's roughly 1,000 police departments will take time to assess.
Body camera testimony and the courtroom record
The prosecution's case leaned heavily on the deputy's own body camera footage. According to court testimony, Massey picked up a pot of boiling water from her stove, prompting Grayson to back away; Grayson testified he took Massey's repeated statement, "I rebuke you in the name of Jesus," as a threat. The body camera showed Grayson pointing his gun at Massey and threatening to shoot her before she apologized and dropped to the floor, at which point he fired three times, striking her. Sangamon County State's Attorney John Milhiser said in court that Grayson declined to offer medical care, and First Assistant State's Attorney Mary Beth Rodgers quoted Massey's final words as "I'm sorry." With Grayson's death, the appellate record on his conviction will likely be affected, as a deceased defendant's direct appeal typically becomes moot, though civil proceedings and any remaining claims could continue against other parties.
Key points
- Sean Grayson died Sunday at age 32, roughly six months into a 20-year sentence for second-degree murder, attorney Daniel Fultz said.
- Grayson had Stage 4 colon cancer that had spread to his liver, lungs and rectum, though the official cause of his death has not been confirmed.
- He was convicted of fatally shooting Sonya Massey, 36, in her home on July 6, 2024, after she called 911 to report a prowler.
- Body camera footage showed Massey dropping to the floor and apologizing before Grayson fired three times and declined to render medical aid.
- The killing prompted the Sonya Massey Act, signed by Gov. JB Pritzker, tightening law enforcement hiring background checks, and a $10 million county settlement with Massey's family.
Grayson's death before the completion of his sentence means the family of Sonya Massey may not see the full measure of criminal accountability play out through the appellate process, and civil claims tied to his individual conduct could face additional legal complexity. The unresolved question of whether his medical condition should have triggered earlier release also raises concerns about how seriously the Illinois Prisoner Review Board weighs terminal illness in similar future cases.
