Sean Grayson, a former Illinois sheriff’s deputy convicted in the 2024 killing of Sonya Massey, dies in prison at age 32, according to his attorney. Multiple outlets report he was serving a 20-year sentence at the time of his death.

The shooting occurred after Massey called 911 from inside her home to report a possible prowler, and Grayson fired the fatal shots. CBS News and NPR state he was found guilty of second-degree murder last October. Several outlets add that he was diagnosed with colon cancer and that his medical condition was discussed during his incarceration, including reports of a diagnosis in 2023.

Outlets also differ slightly on timing details (some cite the death occurring Sunday and shortly after noon) and on cancer-related information, but they broadly agree on the conviction, sentence length, and circumstances leading to the fatal shooting. The lawyer says the cause of death has not been publicly released, and at least one outlet notes Grayson’s request for medical release was denied in July.
