Former Sangamon County Sheriff's Deputy Sean Grayson, who was convicted last year of shooting an unarmed woman, has begun serving his 20-year prison sentence with the Illinois Department of Corrections in an undisclosed location. IDOC confirmed Grayson is in their custody but won't disclose his whereabouts, citing safety and security reasons.

Why it matters

Grayson's killing of an unarmed Sonya Massey in her kitchen drew nationwide attention, following high-profile cases of police violence against Black individuals. His prosecution and conviction became national news, making him a high-profile inmate who poses unique security risks in prison.

The details

Grayson and his partner responded to Massey's 911 call about a prowler. During the encounter, Grayson drew his gun and fatally shot Massey in the head after she said "I rebuke you in the name of Jesus." Grayson was initially charged with first-degree murder but was convicted of second-degree murder. He is also battling advanced forms of cancer that require specialized medical care.

  • Grayson was sentenced on January 29, 2026.
