Former Illinois Deputy Sean Grayson Gets 20 Years for Killing Sonya Massey

Jurors applied Illinois’ second-degree standard that accepts an honest yet unreasonable belief of danger.

Overview

  • Judge Ryan Cadagin imposed the maximum 20-year prison term, followed by two years of supervised release, with credit for time already served.
  • The judge denied Grayson’s motion for a new trial before sentencing, closing off his immediate bid to overturn the October conviction.
  • Grayson apologized in court, calling his actions “terrible decisions,” as his request for a six-year term citing advanced cancer was rejected.
  • Body-camera footage showed a confrontation over a pot of boiling water and Grayson’s threat to shoot before he fired three rounds that killed Massey in her home.
  • The case led to a $10 million settlement with Massey’s family and spurred reforms, including a DOJ agreement on training and data and Illinois’ Sonya Massey Act on hiring transparency.
