Sean Grayson, a former police officer convicted of murdering Black woman Sonya Massey in July 2024, died in an Illinois state prison at age 32.

Grayson shot Massey during a volatile confrontation at her home after she reported a suspected intruder. He later claimed he fired because he feared she would throw boiling water on him, a statement that has not convinced the public. The incident sparked protests across the United States and prompted President Joe Biden to call for justice for Massey.

While in prison, Grayson was receiving treatment for colon cancer. His lawyer, Daniel Fultz, confirmed his death but withheld details. Medicare‑related health concerns had led to an unsuccessful appeal for early release on medical grounds.

Representatives of Massey’s family said, “Grayson’s death in custody from cancer does not bring Sonya back,” adding that the family will continue to grieve her loss. The death has returned attention to the broader debate over criminal justice, police accountability, and the conditions of inmates with serious illnesses.

Illinois authorities have been briefed by the BBC; the investigation continues to assess the circumstances surrounding both the murder and the officer’s death.
