Officer convicted in Sonya Massey killing dies in prison, closing legal chapter

Sean Grayson, the former Illinois deputy convicted of second-degree murder for shooting Sonya Massey in 2024, died in prison on August 23, 2026, at 32. He was serving a 20-year sentence. Massey had called 911 to report an intruder. Grayson's death ends the case's legal proceedings, though questions over police oversight and use-of-force training remain unresolved.
