Former Deputy in Sonya Massey Killing Dies in Prison
Sean Grayson, the former Sangamon County sheriff's deputy whose fatal shooting of Sonya Massey became a national flashpoint over police use of force, died Sunday while serving a 20-year prison sentence. He was 32.
Grayson's attorney, Daniel Fultz, confirmed his client's death but declined to provide additional details about the circumstances. His death came about six months into his sentence, which he began after being convicted in October of second-degree murder in Massey's killing.
Massey, a 36-year-old Black woman, had called 911 on July 6, 2024, to report a possible prowler outside her Springfield, Illinois, home. Grayson and another deputy, Dawson Farley, responded. Body camera footage of the encounter showed Massey crouching in her kitchen and apologizing moments before Grayson shot her in the face. Grayson fired three times, striking Massey, who was pronounced dead at a hospital.
Grayson, who was White, was fired after the shooting and initially charged with first-degree murder. A jury found him guilty of second-degree murder after his defense argued he feared Massey would throw hot water at him. At his January sentencing, Judge Ryan Cadagin imposed the maximum sentence: 20 years in prison.
A Cancer Diagnosis and Denied Release
Before the shooting, Grayson had been diagnosed with colon cancer. At sentencing, his attorneys said the disease had spread to his liver and lungs, and later reports indicated he had been diagnosed with Stage 4 colon cancer that spread to his liver, lungs, and in some cases, rectum. At trial, he testified he believed Massey was going to throw boiling water at him after she said, "I rebuke you in the name of Jesus," which he interpreted as a threat.
In May, months into his sentence, Grayson sought early release under an Illinois law for prisoners with terminal illnesses or serious medical conditions. The Illinois Prisoner Review Board denied his request in July. According to NBC 5 Chicago, the board's spokesperson, Liz Mitchell, confirmed the denial. State's Attorney John Milhiser had opposed the mission in a letter, writing that release "would be a miscarriage of justice" and "an insult to Sonya Massey's memory and family."
Grayson's death came less than a month after the board's decision. The cause of death was not immediately clear, though several sources reported he had been undergoing treatment and that his condition had deteriorated. His attorneys had argued at the sentencing hearing that the disease had advanced, and some outlets reported he was receiving medical care outside the prison facility, according to NPR Illinois.
Reactions from the Massey Family's Attorneys
Massey's family attorneys, Ben Crump and Antonio Romanucci, issued a statement after learning of Grayson's death. "Sonya's death was injustifiable, and she should be alive today," they said. "Sean Grayson's death in custody from cancer does not bring Sonya back. We wish his family prayers of peace, as we do for all who grieve a loved one. Sonya's family knows that pain all too well and will grieve her loss the rest of their days."
The statement was reported by multiple outlets, including NBC, CBS, Chicago Tribune, and BBC.
An Outcry That Led to Reform
The killing of Sonya Massey sparked widespread outrage and demonstrations. Then-President Joe Biden said she "should be alive today," according to the BBC. The U.S. Department of Justice opened a civil rights investigation and later reached an agreement with Sangamon County to implement new training and procedures, including enhanced de-escalation training and crisis response programs. Illinois also passed the Sonya Massey Act, which requires stricter background checks for law enforcement hires. The county reached a $10 million settlement with Massey's family.
Questions about Grayson's background also surfaced. Before joining Sangamon County, he had worked for multiple agencies across Illinois, and reports of previous DUI arrests and a military discharge raised concerns. The county maintained that he met required background checks.
Who Was Sean Grayson?
Grayson, who was 32, had been imprisoned for six months at the time of his death. A jury in October, Peoria County jury, found him guilty of second-degree murder, rejecting more serious charges. His body camera was activated until after masking, so the crucial moment was captured on his partner's camera.
He had faced particular scrutiny over his law enforcement record. Before joining the Sangamon County Sheriff's Office, he had worked for several departments in central Illinois, and his history included a federal court martial and a pair of DUI arrests. Despite the national attention, his trial focused on the incident itself, and these details were not presented to the jury.
His death has left family, legal representatives, and community members to react. While the official cause was pending, his cancer likely contributed to the cystic complications. He was found guilty of killing a woman who had reached out for help, and his story remains a painful chapter in the ongoing debate over law enforcement accountability.
