SPRINGFIELD, Ill. (CIVITAS) — A former Illinois sheriff’s deputy was sentenced Thursday to 20 years in prison for fatally shooting Sonya Massey, who had dialed 911 to report a possible prowler outside her Springfield home.

Sean Grayson, 31, was convicted in October. He received the maximum sentence and has been incarcerated since the incident. During the sentencing, Grayson expressed regret, stating, “I made a lot of mistakes that night... I froze.”

Massey’s family, who lobbied for the maximum sentence, discussed the profound impact of her death on their lives, stressing that her children will grow up without their mother. Massey’s mother shared her fear and hesitation to call the police, reflecting the fear of another such incident.

Upon hearing the sentence, Massey’s relatives reacted with relief, but her daughter, Summer, remarked, “Twenty years is not enough.” The tragic event unfolded on July 6, 2024, when Massey, who faced mental health challenges, called for police assistance, fearing a prowler.

Body camera footage showed that Grayson and a fellow deputy entered Massey’s home, where the situation quickly escalated. Grayson drew his weapon after Massey, holding a pot, refused orders to set it down. He shot her, claiming fear of being scalded.

Charged with three counts of first-degree murder, Grayson ultimately received a conviction for the lesser charge of second-degree murder, which drew outrage from Massey’s family. The case raised larger questions about law enforcement interactions with individuals in vulnerable situations. A settlement of $10 million was negotiated for Massey’s family, prompting changes in local law enforcement practices and training.

Following the incident, the U.S. Justice Department initiated an inquiry that led to improved training and background checks for police candidates in the county.
