Sonya Massey was a 36-year-old Black mother who called 911 on July 6, 2024.
She reported a possible prowler at her Springfield home.
Deputies responded quickly to the address in Sangamon County.
Sean Grayson and his partner searched outside the residence first.
They found no intruder and entered the home.
Officers asked Massey for identification during the interaction.
She began looking for her ID while deputies stood nearby.
A pot of boiling water sat on the stove during the exchange.
Grayson directed Massey to move away from the hot pot.

I rebuke you in the name of Jesus
twice.
Grayson immediately drew his firearm in response.
He threatened to shoot her in the face if she did not comply.
Massey apologized and ducked behind the counter.
Grayson fired three shots striking her in the head and face.
Body camera footage documented the rapid escalation clearly.
