Former Illinois Deputy Sean Grayson Sentenced to 20 Years in Sonya Massey Murder Case
A former Illinois sheriff’s deputy, Sean Grayson, was sentenced Thursday to 20 years in prison, followed by two years of supervised probation, for the second-degree murder of Sonya Massey. The sentencing concludes a case that sparked outrage and led to legislative changes in Illinois regarding police background checks.
Grayson, for the first time, admitted wrongdoing against Massey, a Black mother of two, during a statement in court. Massey had called 911 in July 2024, reporting a possible prowler outside her Springfield home, leading to the encounter with grayson. “I was very unprofessional that night,” Grayson said, adding, “She didn’t deserve to be yelled and cussed at and called names. Nobody deserves that.”
Judge Ryan Cadigan of the 7th Judicial Circuit Court of Illinois handed down the maximum penalty, stating that Grayson’s “bit of unreasonable rage needs to be deterred.” The judge denied a motion filed by the defense for a new trial, submitted in November.
The courtroom was filled with emotional testimony from Massey’s family. Her daughter, summer massey, described the “traumatic impacts” of her mother’s murder, stating, “it does not feel like he truly understands or cares about the damage he has caused.” Her brother, Malakai Massey, spoke of “unimaginable” pain, saying, “My soul is ripped, it’s like a part of me is really dead.”
Outside the courthouse, approximately 50 protesters chanted “say her name, Sonya Massey,” while family members inside reacted to the sentencing with shouts of “yes” and raised fists.
The conviction stemmed from jury instructions that allowed jurors to consider the lesser charge of second-degree murder instead of first-degree murder,following nearly 12 hours of deliberation in October. A second-degree murder conviction carries a penalty of four to 20 years in prison. Under Illinois law, grayson is likely eligible for day-for-day credit for good behavior, potentially reducing his sentence to 10 years. A first-degree murder conviction would have carried a sentence of 45 years to life, with no possibility of day-for-day credit.
sangamon County State’s Attorney John Milhiser argued for the maximum sentence, stating, “If the max were more we would ask for more,” emphasizing the need to “deter others from committing the same crime.”
Defense attorney Mark wykoff presented a plea for leniency, citing grayson’s deteriorating health. Wykoff revealed that Grayson was diagnosed with Stage 3 colon cancer in 2023, which has since progressed to Stage 4 and spread to his liver, rectum, and lungs. Wykoff also argued the case should be focused on the events within Sangamon County, stating it was “not a referendum on the rest of the country.”
The initial charges against Grayson followed his claim that Massey had threatened him with a pot of boiling water. However, First Assistant State’s Attorney Mary Beth Rodgers asserted that Massey had complied with Grayson’s order to drop the pot, while the defense maintained Massey escalated the situation.
Massey’s death ignited calls for justice and ultimately led to the passage of the Sonya Massey Act in Illinois, mandating stricter background checks for prospective police hires. Her father, James Wilburn, expressed relief at the sentencing, stating, “He showed no remorse…that knocked the smirk off.” Wilburn reiterated t
