The Shooting and Conviction
On July 6, 2024, Sonya Massey, a 36-year-old mother of two, called 911 to report a possible prowler outside her Springfield-area home. Former Sangamon County sheriff’s deputy Sean Grayson and Deputy Dawson Farley responded. Body-camera footage captured Grayson ordering Massey to move a pot of boiling water, threatening to shoot her, and then firing three shots that struck her in the face. She was pronounced dead at St. John’s Hospital.
A Peoria County jury convicted Grayson of second-degree murder in October after a trial that began with first-degree murder charges. He received the statutory maximum of a 20-year prison term in January, followed by two years of mandatory supervised release.
Background and Legislative Response
Grayson’s hiring history—six agencies in four years, two DUIs, a discharge from the U.S. Army for “serious misconduct,” and prior complaints—prompted scrutiny of law-enforcement vetting practices. Illinois lawmakers enacted the Sonya Massey Act, requiring agencies to conduct more thorough background checks on applicants. Governor JB Pritzker signed the law, which took effect at the start of the year.
The U.S. Department of Justice opened a civil-rights investigation after the shooting and later reached a settlement with Sangamon County that includes revised training for encounters with individuals experiencing mental-health crises and the creation of a mobile crisis response program. In early 2025, Sangamon County agreed to a $10 million settlement with the Massey family.
Medical Release Request and Death
Grayson was diagnosed with stage 3 colon cancer in 2023; the disease progressed to stage 4 and spread to his liver, lungs and rectum. He filed a medical-release application under the 2022 Illinois law that allows terminally ill inmates to seek early release. The Illinois Prisoner Review Board denied the request in a unanimous 3-0 vote in July.
Grayson died later this year while serving his sentence. His attorney Daniel Fultz confirmed the death but did not disclose the cause. Several outlets noted that it was unclear whether cancer was the direct cause.
