Sean Grayson dies at 32: Former Deputy who killed Sonya Massey dies in prison
Former Illinois sheriff’s deputy, Sean Grayson.
Sean Grayson, the former Illinois sheriff’s deputy who was sentenced to 20 years in prison for the fatal shooting of Sonya Massey, has died at the age of 32 after battling advanced colon cancer.
Grayson’s attorney, Daniel Fultz, confirmed his client’s death Sunday but did not provide additional details about the circumstances. Grayson had been incarcerated for about six months and had recently sought an early medical release because of his deteriorating health.
His death comes less than a month after the Illinois Prisoner Review Board rejected his request for medical release, leaving him in custody while he battled stage 4 cancer.
The case had drawn national attention following the release of police body-camera footage showing the encounter between Grayson and Massey inside her Springfield-area home in July 2024.
Who Was Sean Grayson?
Grayson was a former Sangamon County sheriff’s deputy in Illinois who responded to a 911 call from Massey on July 6, 2024. Massey had contacted authorities after becoming concerned about a possible prowler outside her home.
Grayson and another deputy went to Massey’s residence and entered the home during the response. The encounter quickly escalated after Massey picked up a pot containing boiling water.
According to the account presented in court, Grayson moved away from Massey and made a comment about the hot water. Massey then invoked her Christian faith and said she “rebuke[d]” him in the name of Jesus.
Grayson subsequently pointed his firearm at Massey and threatened to shoot her.
Massey apologized and dropped to the floor, but Grayson fired three shots, striking her. She was taken to a hospital and later pronounced dead.
The shooting sparked widespread outrage and renewed discussions about police use of force, accountability and the treatment of Black Americans during encounters with law enforcement.
What Happened to Sonya Massey?
Sonya Massey was a 36-year-old Black woman who called police for assistance before she was fatally shot inside her home.
The circumstances of her death became the focus of a criminal investigation and subsequent prosecution of Grayson. Prosecutors argued that the shooting was unjustified and that Grayson escalated the encounter.
Grayson was ultimately convicted of second-degree murder and sentenced to 20 years in prison.
The case received national attention, particularly after body-camera footage of the encounter became public. The footage showed the interaction between Massey and the responding deputies shortly before the shooting.
The killing also generated renewed calls for police accountability and changes in how officers respond to people experiencing potentially volatile or emotionally charged situations.
Sean Grayson Was Battling Stage 4 Colon Cancer
Grayson’s health became a major issue after his conviction.
He had been diagnosed with stage 3 colon cancer in 2023, before the shooting that killed Massey. By the time he was sentenced in January, his cancer had progressed to stage 4 and had spread to his liver, lungs and rectum.
Medical evidence submitted during his request for release described the illness as “irreversible and incurable.”
A medical professional who evaluated Grayson said he was likely to die within 18 months because of the disease.
However, the assessment also concluded that Grayson was not medically incapacitated. According to the application, his condition did not prevent him from performing ordinary daily activities without assistance.
That distinction became significant in determining whether he qualified for early release under Illinois law.

Why Was Sean Grayson Denied Medical Release?
Grayson sought release under the Joe Coleman Act, an Illinois law that provides a mechanism for certain incarcerated people who are terminally ill or medically incapacitated to seek release.
The Illinois Prisoner Review Board voted 3-0 on July 31 to deny his application.
Sangamon County State’s Attorney John C. Milhiser opposed the request. He argued that Grayson’s medical condition did not eliminate the danger he posed to other people.
Massey’s family also strongly opposed his release.
The argument against release focused not only on Grayson’s medical condition but also on the circumstances surrounding Massey’s death. Prosecutors maintained that Grayson’s actions demonstrated that he remained a danger despite his cancer diagnosis.
Grayson’s Account of the Shooting
In a handwritten statement included in his medical release application, Grayson continued to maintain that Massey had attacked him with a pot of boiling water.
He described the incident as an attack and said he fatally shot Massey.
That account contrasted with the prosecution’s position and the evidence presented during the criminal case, which resulted in his conviction for second-degree murder.
The dispute over the circumstances of the shooting remained a significant part of the broader debate surrounding Grayson’s request for medical release.
Massey’s Family Opposed His Release
Massey’s relatives strongly opposed the possibility of Grayson leaving prison early.
Her mother, Donna Massey, urged the Prisoner Review Board to reject the request, arguing that Grayson should remain incarcerated for his role in her daughter’s death.
The family’s position reflected a broader concern over the possibility that Grayson could have been released after serving only a small portion of his sentence.
The board ultimately rejected his application, meaning Grayson remained imprisoned until his death.
What Happens After Sean Grayson’s Death?
Grayson’s death brings his criminal sentence to an end, but the wider legal and public consequences of the Sonya Massey case remain significant.
The case has continued to draw attention to questions surrounding police accountability, use of force, officer training and how law enforcement responds to people who call for help.
Massey’s death also became part of a broader national conversation about police interactions with Black residents and the importance of transparency when deadly force is used.
Grayson’s death does not alter his conviction for second-degree murder. He died while serving the 20-year sentence imposed following his conviction.
