Former Illinois sheriff’s deputy Sean Grayson, who was sentenced to 20 years in prison for the fatal shooting of Sonya Massey, has died while serving his sentence, according to his attorney.
Grayson, 32, died early Sunday, August 23, 2026, his defense attorney, Daniel Fultz, confirmed to The Post.
The former deputy had been serving a 20-year sentence for second-degree murder after being convicted over the July 2024 shooting of Massey, a 36-year-old Black mother who had called police to her Springfield, Illinois, home to report a possible prowler.
Grayson had served only about six months of his sentence before his death.

Grayson had advanced cancer
Grayson had previously been diagnosed with colon cancer before the shooting that resulted in Massey’s death.
In January 2026, his attorney revealed that the cancer had progressed to his liver and lungs and subsequently sought an early medical release from prison.
However, a three-member Illinois Prisoner Review Board voted unanimously in July to reject his request.
Fultz was unable to confirm whether Grayson’s death was directly related to his cancer diagnosis.
His death brings an unexpected end to the imprisonment of a former law enforcement officer whose actions during the 2024 incident generated nationwide outrage and renewed discussions about police use of force.
Fatal encounter with Sonya Massey
Massey called 911 on July 6, 2024, because she believed there might be an intruder or prowler near her home.
Grayson and another deputy responded to the call.
Body-camera footage released during the subsequent investigation showed the confrontation that unfolded inside Massey’s home.
At one point, Massey was moving a pot of hot water from the stove when she told Grayson, “I rebuke you in the name of Jesus.”
Grayson subsequently pulled out his firearm.
Massey apologized and ducked as Grayson fired three shots, striking her in the face.
She died from her injuries.
The incident quickly attracted national attention, particularly because Massey had contacted police herself seeking assistance.
Grayson claimed he feared hot water
During the legal proceedings, Grayson and his attorneys argued that he believed Sonya Massey posed a threat because he feared she would throw or use the boiling water against him.
Prosecutors rejected his justification and argued that the use of deadly force was not warranted under the circumstances.
Body-camera footage became a central piece of evidence in the case and was widely viewed following the shooting.
The case triggered protests and renewed public debate over systemic racism, police accountability and the treatment of Black Americans during encounters with law enforcement.
The U.S. Department of Justice also conducted a review following the shooting.
Convicted and sentenced to 20 years
Grayson was convicted of second-degree murder in October 2025.
He was subsequently sentenced in January 2026 to the maximum possible prison term of 20 years.
The sentence meant that he would spend decades behind bars for the shooting that ended Massey’s life.
However, his declining health later led his legal team to seek compassionate or medical release.
The Illinois Prisoner Review Board ultimately rejected that request in July.
Grayson died roughly one month after the board’s decision.
Massey’s family responds
Following news of Grayson’s death, attorneys representing Massey’s family issued a statement expressing sympathy for his relatives while stressing that his death did not erase the loss suffered by Sonya’s family.
Civil rights attorneys Ben Crump and Antonio Romanucci said Grayson’s death did not bring Massey back.
“Sonya Massey’s death was unjustifiable, and she should be alive today,” the attorneys said in a statement to WLS.
They also extended prayers to Grayson’s family, noting that Massey’s relatives understood the pain of losing a loved one.
The attorneys emphasized that Sonya Massey’s family would continue to live with the consequences of her death.
A case that sparked national outrage
Sonya Massey’s shooting became one of the most closely watched police cases in Illinois in 2024.
The circumstances surrounding her death generated widespread anger because she had called authorities for help but was ultimately fatally shot by one of the responding deputies.
The release of the body-camera footage intensified public criticism and contributed to protests demanding police accountability.
Grayson was eventually fired from his position and prosecuted for Massey’s death.
His conviction and subsequent 20-year sentence were viewed by Sonya Massey’s supporters as an important step toward accountability.
However, her family and advocates have repeatedly stressed that no legal outcome can restore the life that was lost.
Grayson’s death closes one chapter
With Grayson’s death, the criminal case against him effectively comes to an end, although the broader questions raised by Sonya Massey’s shooting continue to resonate.
Massey was a mother, daughter and member of her community whose death became a symbol in discussions about police violence and racial justice in America.
Her family has continued to remember her while seeking accountability for the circumstances surrounding her death.
Grayson’s attorney confirmed his death but did not provide details about the circumstances or confirm whether his cancer was responsible.
For Sonya Massey’s loved ones, however, the central reality remains unchanged: Sonya Massey lost her life during an encounter with police after making a call for help.
Her death continues to prompt difficult questions about police training, accountability, the use of deadly force and the protection of vulnerable people during emergency calls.
