A former Illinois deputy has been sentenced to 20 years for fatally shooting Sonya Massey, a Black woman who called 911 for help.

Sean Grayson, 31, was convicted in October of second-degree murder. Grayson, who is white, received the maximum possible sentence and has been in police custody since being charged in the killing.

Massey’s family members, who were sitting in the court, celebrated his sentence with a loud cheer: “Yes!” The judge admonished them.

Grayson apologized during the sentencing, saying he wished he could bring Massey back and spare her family the pain he caused.

“I made a lot of mistakes that night. There were points when I should’ve acted, and I didn’t. I froze,” he said. “I made terrible decisions that night. I’m sorry.”
