Sean Grayson, a former Illinois sheriff's deputy, died Sunday while serving a 20-year prison sentence for the fatal shooting of Sonya Massey, his attorney Daniel Fultz confirmed, as reported by infohub.kz.
Grayson, 32, was convicted of second-degree murder in October for the July 2024 shooting of Massey, a 36-year-old Black woman who had reported a possible prowler outside her Springfield-area home. Body camera video showed Massey crouching in her kitchen and apologizing moments before Grayson shot her in the face.
He was sentenced in January to the maximum 20 years in prison. Grayson had been diagnosed with colon cancer before the killing, and his attorneys said at sentencing that the disease had spread to his liver and lungs. In May, he sought medical release under an Illinois law for prisoners with terminal illnesses, but the Illinois Prisoner Review Board denied his request last month.
Massey called 911 early on July 6, 2024, to report someone prowling outside her home. Grayson and another Sangamon County sheriff's deputy responded. Video showed Grayson directing Massey to remove a pot of hot water from the stove. As she held the pot, Massey told the deputies, "I rebuke you in the name of Jesus." 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.
The other deputy, Dawson Farley, later testified that he did not consider Massey a threat and drew his own weapon only after Grayson did. Grayson was fired after the shooting and charged with first-degree murder, but jurors convicted him of the lesser charge of second-degree murder after Grayson argued he feared Massey would throw the hot water at him.
Massey's killing drew national attention and protests and raised questions about how Grayson had moved through several law enforcement agencies before being hired by the Sangamon County Sheriff's Office. Illinois lawmakers later passed the Sonya Massey Act, requiring law enforcement agencies to more closely review an applicant's previous employment records before hiring.
The Justice Department also opened a civil rights investigation after 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, including additional training for interactions with people with behavioral health disabilities and development of a mobile crisis response program.
