Former Sangamon County Sheriff's Deputy Sean Grayson died on Sunday while serving his 20-year prison sentence for the second-degree murder of Sonya Massey. According to multiple reports, Grayson had been battling Stage 4 colon cancer and was denied a medical release request by the Illinois Prisoner Review Board last month.

The incident occurred on July 6, 2024, when Massey called police for help with a possible prowler outside her home. Grayson and another deputy responded to the call. Body camera footage from Grayson's partner showed Massey crouching in her kitchen and apologizing moments before Grayson shot her in the face.

Grayson was found guilty of second-degree murder in October 2024, after arguing that he feared Massey would throw a pot of hot water at him. The case drew national attention and led to protests over police use of force. Illinois lawmakers later passed the Sonya Massey Act, requiring more thorough reviews of an applicant's previous employment records before hiring officers.

The Justice Department also opened a civil rights investigation following Massey's death, resulting in an agreement with Sangamon County that mandated changes to policing and emergency response procedures. These changes included additional training for interactions with individuals with behavioral health disabilities and the development of a mobile crisis response program.

The family of Sonya Massey expressed shock at Grayson's death, stating it was 'not what justice looks like.' According to Daily Mail, Massey's cousin Sontae Massey said the family struggled to accept the news and wanted to see Grayson's body. The family also criticized the initial charge against Grayson, arguing he should have been charged with first-degree murder.
