What to know about the murder trial of an Illinois sheriff deputy who killed Sonya Massey

The murder trial of an Illinois sheriff’s deputy charged with killing Sonya Massey, a Black woman shot in her home last year after calling police for help, is set to begin Monday. Sean Grayson, 31, responding to a call about a suspected prowler, fired on the 36-year-old Massey in her Springfield home early on July 6, 2024, after confronting her about how she was handling a pan of hot water Grayson had ordered removed from her stove. Massey's killing raised new questions about U.S. law enforcement shootings of Black people in their homes and it prompted a change in Illinois law requiring fuller transparency on the background of candidates for law enforcement jobs.
