Sean Grayson, the former Illinois sheriff’s deputy serving a 20-year sentence for the fatal shooting of Sonya Massey, died Sunday in prison at age 32, according to his defense attorney, Daniel Fultz. Grayson was convicted of second-degree murder in October following the July 6, 2024, encounter inside Massey’s Springfield-area home, where she had called 911 to report a possible prowler.
Background of the Sonya Massey Shooting and Conviction
Massey, a 36-year-old Black woman, called authorities early on July 6, 2024, prompting Grayson and another Sangamon County sheriff’s deputy to respond to her home. Body camera footage later captured Grayson directing Massey to remove a pot of hot water from her stove. As she held the pot, Massey told the deputies, “I rebuke you in the name of Jesus.” According to video evidence, Grayson threatened to shoot her, drew his handgun, and ordered her to drop the pot. Massey apologized and ducked behind a kitchen counter before Grayson fired three times, striking her in the face.
Dawson Farley, the other responding deputy, testified that he did not consider Massey a threat and only drew his own weapon after Grayson did. Grayson was fired following the shooting and initially charged with first-degree murder. Jurors convicted him of the lesser charge of second-degree murder after Grayson argued he feared Massey would throw the hot water at him. In January, a judge sentenced Grayson to the maximum 20-year prison term.
Did You Know? Before her death, Sonya Massey called 911 to report a possible prowler outside her Springfield-area home, which led to the fatal July 6, 2024, encounter documented by police body camera footage.
Medical History and Denied Release Request
Grayson’s legal team stated during his sentencing that he had been diagnosed with colon cancer prior to Massey’s killing, and that the disease had spread to his liver and lungs. In May, only months into his sentence, Grayson sought medical release under an Illinois law for prisoners with terminal illnesses or serious medical conditions. The Illinois Prisoner Review Board voted unanimously to deny his application last month.

Defense attorney Daniel Fultz confirmed Grayson’s death on Sunday but declined to provide further details. Attorneys Ben Crump and Antonio Romanucci, who represented Massey’s family in a civil settlement, issued a statement noting that Grayson’s death in custody does not bring Massey back.
In this instance, Massey’s death catalyzed both statutory reforms in police hiring and a federal civil rights agreement requiring enhanced behavioral health and crisis response training.
Policy Changes and Broad Impact
The fatal encounter drew national attention, sparked widespread protests, and triggered intense scrutiny regarding how Grayson had moved through several law enforcement agencies prior to his hiring by the Sangamon County Sheriff’s Office. In response, Illinois lawmakers passed the Sonya Massey Act, which requires law enforcement agencies to more closely review an applicant’s previous employment records before hiring an officer.

Additionally, the United States Department of Justice opened a civil rights investigation following Massey’s death and later reached an agreement with Sangamon County, its sheriff’s office and other agencies requiring changes to policing and emergency response. Those required measures included additional training for interactions with people with behavioral health disabilities and development of a mobile crisis response program.
