Grayson was serving a 20-year sentence for second-degree murder after a jury convicted him in October 2025 . He had been incarcerated for approximately six months at the time of his death . The Illinois Department of Corrections has not released official details about the cause or manner of death .
Grayson’s attorney, Daniel Fultz, confirmed his client died on Sunday but did not immediately provide additional details about what happened . No official cause of death has been released by prison authorities, the Illinois Department of Corrections, or Grayson’s representatives .
It is not currently confirmed whether cancer caused Grayson’s death . While he had been battling advanced colon cancer for several years, officials have not established a direct connection between his medical condition and his passing .
Sean Grayson was a former Sangamon County sheriff’s deputy who became nationally known after the July 2024 shooting of Sonya Massey . He was 32 years old at the time of his death .
Before joining the Sangamon County Sheriff’s Office in May 2023, Grayson had worked for six different law enforcement agencies over four years . His record included two DUIs, a discharge from the U.S. Army for “serious misconduct,” and prior complaints .
Sonya Massey, a 36-year-old Black mother of two, called 911 on July 6, 2024, to report a possible prowler near her Springfield, Illinois, home . Grayson and another deputy responded to the call .
Body-camera footage from Grayson’s partner showed the encounter inside Massey’s kitchen . According to prosecutors, Grayson directed Massey to remove a pot of boiling water from the stove. Massey then said, “I rebuke you in the name of Jesus” . Grayson responded by threatening to shoot her in the face before firing three times . One shot struck Massey in the face, and she was pronounced dead at a hospital .
Grayson did not activate his own body camera until after the shooting . In his official report and later court testimony, he maintained that he believed Massey was going to throw the boiling water at him .
Grayson had been diagnosed with colon cancer in 2023, prior to the shooting . According to court documents and his attorneys, the cancer later progressed to Stage 4 and spread to his liver, lungs, and rectum .
In May 2026, Grayson applied for early release under Illinois’ Joe Coleman Medical Release Act, which allows seriously ill prisoners to seek release under certain conditions . His attorneys argued that his cancer was terminal, with a medical professional estimating he was likely to die within 18 months .
The Illinois Prisoner Review Board unanimously denied his request in a 3-0 vote in July 2026 . Sangamon County State’s Attorney John Milhiser had opposed the release, noting that Grayson had cancer when he committed the murder and that his condition was considered at sentencing .
Sonya Massey’s family also opposed his release. Her cousin Sontae Massey told Capitol News Illinois, “He’s a killer. I apologize that he must suffer, but he has to pay for what he did” .
A Peoria County jury convicted Grayson of second-degree murder in October 2025 . He had originally faced first-degree murder charges. In January 2026, Judge Ryan Cadagin sentenced Grayson to the maximum 20 years in prison .
The Illinois Department of Corrections has not yet released an official statement regarding Grayson’s death . His attorney did not provide information about where Grayson was being held or the circumstances of his death .
Additional details may emerge if an autopsy is conducted or if the family chooses to release further information. At this time, all information remains preliminary .
