SPRINGFIELD, Ill. (WAND) — A motion to reconsider Sean Grayson's sentence was denied Friday.

The former Sangamon County sheriff's deputy was convicted of second-degree murder in October 2025 for the police killing of Sonya Massey after she dialed 911 to report a prowler at her home. He was sentenced to 20 years in prison in January.

Grayson did appear in court virtually for the hearing. His attorney said that he plans to file an appeal with a higher court.
