Sean Grayson Death and Obituary

Sean Grayson, the former Sangamon County Sheriff’s deputy convicted in the fatal shooting of Sonya Massey, has died in prison at the age of 32.

Grayson’s death was confirmed by his defense attorney, Daniel Fultz, on August 23, 2026. He died while serving a 20-year prison sentence after being convicted of second-degree murder in connection with the July 2024 shooting of Massey.

According to reporting from Capitol News Illinois, Grayson had served less than a year of his sentence when he died. His attorney confirmed the death but did not immediately provide additional details about the circumstances.

Former Illinois Deputy Sean Grayson Dies in Prison

Grayson was a former deputy with the Sangamon County Sheriff’s Office in Illinois. His name became nationally known following the July 6, 2024, shooting death of Sonya Massey, a 36-year-old woman who had called 911 to report a possible prowler outside her home.

Grayson and another deputy responded to the call. Body-camera footage from the encounter later became central to the criminal case and generated widespread public attention.

Grayson was ultimately convicted of second-degree murder in October 2025 and sentenced in January 2026 to the maximum 20-year prison term.

Sean Grayson Cause of Death

At the time of the initial reports announcing his death, the official cause of death had not been disclosed.

Grayson had previously been diagnosed with colon cancer, which had progressed to Stage 4 and spread to his liver and lungs. His attorneys sought medical release because of his terminal illness, but the Illinois Prisoner Review Board denied the request.

Although his advanced cancer has been widely reported, it should not be stated definitively as the cause of his death unless an official authority or his family confirms it.
