Quick Summary

Former Illinois sheriff's deputy Sean Grayson, convicted of fatally shooting Sonya Massey in her home in 2024, has died at the age of 32, according to his attorney Daniel Fultz. Grayson was six months into serving a 20-year sentence for second-degree murder and had been diagnosed with Stage 3 colon cancer that had progressed to Stage 4 and spread to other parts of his body. The cause of death is not immediately clear. Grayson's case led to the passage of the Sonya Massey Act, which requires stricter background checks for law enforcement hires, and a $10 million settlement to Massey's family was agreed upon by Sangamon County officials in 2025.

Story summary

Sean Grayson, a former Illinois sheriff's deputy, died on Sunday at the age of 32 while serving a 20-year sentence for fatally shooting Sonya Massey, a 36-year-old Black woman, inside her home in Springfield. Grayson was convicted of second-degree murder in October and had been battling Stage 4 colon cancer, which had spread to his liver, lungs, and rectum. He died just six months into his sentence. The shooting occurred on July 6, 2024, after Massey called 911 to report a prowler, and Grayson responded to the call. Body camera video showed that Massey was apologizing moments before Grayson shot her in the face. Massey's family feels that Grayson's death does not bring them justice, as they wanted him to serve his full sentence.
