- Ex-deputy Sean Grayson dies serving 20-year prison term for Sonya Massey killing after medical release denied (foxnews.com)
Former Illinois Sheriff’s Deputy Sean Grayson has died while serving a 20-year prison sentence for the fatal shooting of Sonya Massey, his attorney confirmed Sunday. Details surrounding Grayson’s death were not disclosed.
Grayson, 32, had been battling colon cancer that had advanced to his liver and lungs prior to the shooting. In May, he requested medical release under an Illinois law for inmates with serious or terminal illnesses, but the Illinois Prisoner Review Board denied his petition last month.
The shooting occurred on July 6, 2024, when Massey, a 36-year-old Black woman, called 911 to report suspicious activity near her Springfield-area home. Body-camera footage showed Massey apologizing and appearing confused moments before Grayson fired three shots inside her home, one striking her in the head.
According to prosecutors, Grayson threatened Massey and opened fire after she briefly rose from a crouched position. His partner, Deputy Dawson Farley, testified that he did not view Massey as a threat and only drew his weapon after Grayson fired.
Grayson was fired following the incident. A grand jury initially charged him with first-degree murder, aggravated battery with a firearm, and official misconduct. He pleaded not guilty but was convicted of second-degree murder in October 2024 and sentenced to the maximum 20 years.
Massey’s death sparked national attention, protests, and scrutiny of Grayson’s prior law enforcement employment. In response, Illinois enacted the Sonya Massey Act to strengthen background checks on law enforcement applicants. Additionally, the Justice Department launched a civil rights investigation and reached an agreement with local agencies to improve policing practices, including enhanced training on behavioral health crises and the development of a mobile crisis-response team.
