Sean Grayson, the former Illinois sheriff's deputy convicted of second-degree murder in the fatal shooting of Sonya Massey, died Sunday at age 32 while serving his prison sentence.
Attorney Daniel Fultz confirmed that Grayson died around noon Sunday Central Time, according to TMZ.com. While Fultz declined to provide additional details, sources close to the situation indicated colon cancer was the underlying cause of death.
Grayson had been diagnosed with Stage 3 colon cancer in 2023. His legal team later disclosed that the disease had advanced to Stage 4 and metastasized to his liver, lungs, and rectum. The Illinois Prisoner Review Board denied his request for medical release in July.
The former deputy was approximately six months into a 20-year sentence for the second-degree murder of Massey, a 36-year-old woman who had contacted emergency services to report a prowler at her Illinois residence in 2024. The fatal encounter occurred shortly after deputies responded to her home and was documented on body camera footage.
The shooting ignited widespread public anger, demonstrations, and demands for law enforcement accountability across the nation. The case drew particular attention due to the circumstances surrounding Massey's death and the body camera evidence that captured the incident.
During trial proceedings, Grayson provided testimony explaining his actions on the day of the shooting. He stated that Massey had picked up a pot of boiling water, prompting him to retreat. Grayson testified that he perceived a threat when Massey stated, "I rebuke you in the name of Jesus," believing she intended to throw the scalding water at him.
The conviction marked a significant moment in ongoing national conversations about police use of force and accountability. Grayson's death brings an unexpected conclusion to a case that had galvanized public attention and sparked intense debate about law enforcement practices and the protection of vulnerable community members who seek police assistance.
