Former Deputy Sean Grayson Dies In Prison After Murdering Woman

Sean Grayson, a former Illinois sheriff's deputy who took the life of Sonya Massey while she sought help from 911, has died in prison. He passed away around noon on Sunday, just six months into his twenty-year sentence for second-degree murder. Attorney Daniel Fultz confirmed this to NBC News.

Grayson was thirty-two years old when he died. His defense attorney, Mark Wykoff, revealed at sentencing back in January that the officer had been diagnosed with Stage 3 colon cancer in 2023. The Illinois Prisoner Review Board denied a request for medical release last month despite claims from his legal team that the disease had advanced to Stage 4 and spread to his liver and lungs. Medical files obtained by Capitol News Illinois indicate an Illinois Department of Corrections professional concluded Grayson would likely die within eighteen months.

Yet, there is a strange detail in how he asked for freedom. Grayson did not list terminal illness as the reason for his request. Instead, he applied under a provision covering prisoners expected to become medically incapacitated within six months. He was convicted in October and handed the maximum twenty-year term in January for the July 2024 killing.

Ben Crump and Antonio Romanucci represent Massey's family. They issued a statement on Sunday regarding his death. 'Sonya Massey's death was unjustifiable and she should be alive today,' they said. 'Sean Grayson's death in custody from cancer does nothing to bring Sonya back.' They added that they wished prayers of peace for his grieving family but noted that the relatives know pain all too well and will mourn her loss for the rest of their days.

The tragedy began on the early hours of July 6, 2024. Massey called 911 because she believed a prowler was lurking outside her home in Springfield, Illinois. Grayson and another deputy from Sangamon County searched the property but found no intruder before entering to question her. Inside, he directed her to remove a pot of boiling water from the stove. 'We don't need a fire alarm here,' he reportedly told her.

Massey dropped to the floor after apologizing. She said, 'I rebuke you in the name of Jesus.' Grayson responded by saying, 'I'll fing shoot you right in the fing face,' and drew his gun. The other deputy stepped away from the pot just as the shooting happened. Body-camera footage showed Grayson pointing his weapon at Massey moments before firing three times. One bullet struck her in the head and killed her instantly.

Grayson did not activate his own body camera until after he fired, though the other deputy's camera captured the event. At sentencing, he apologized but later told medical officials that Massey had attacked him during their application under the Joe Coleman Act. The law allows prisoners with terminal illnesses or severe medical incapacity to seek compassionate release. It was named for an eighty-two-year-old decorated Army veteran who died of prostate cancer in prison.

Sangamon County State's Attorney John Milhiser urged the review board to keep Grayson behind bars while they considered his application. 'Critically, Grayson had cancer when he committed this murder and his medical condition was explicitly considered at sentencing,' Milhiser wrote. He argued that releasing him under these circumstances would be a miscarriage of justice and an insult to Massey's memory and family. The prosecutor also noted that Grayson remained a danger despite his deteriorating health, citing his temper and willingness to escalate minor misunderstandings into fatal encounters.

Massey was a single mother of two. Her killing triggered nationwide protests, a review by the US Department of Justice, and renewed scrutiny of police hiring practices. Sangamon County later agreed to pay her family ten million dollars to settle a wrongful-death claim. Massey's cousin Sontae Massey testified against his release, stating he lacked remorse. 'He's a killer,' the cousin said previously. 'I apologize that he must suffer, but he has to pay for what he did.
