Sean P Grayson worked for six law enforcement agencies in four years, with allegations of abuse of power and lying

As vigils for Sonya Massey take place across the US this weekend, a history of unethical and aggressive behavior by the officer who shot her, Sean P Grayson, is emerging. Grayson’s disciplinary file includes accusations of bullying behavior and abuse of power, according to CBS News.

Sonya Massey, a 36-year-old Black woman and mother of two living outside Springfield, Illinois, had called 911 when she thought a prowler was lurking outside her home on 6 July. Grayson and another officer from the Sangamon county sheriff’s office were dispatched and arrived at her home. Instead of helping Massey with a possible intruder, Grayson shot her in the face after she moved a pot of water from her kitchen stove at their request.

Grayson, who is white, has pleaded not guilty to charges of first-degree murder, aggravated battery with a firearm and official misconduct in Massey’s killing. He was fired last week by the Sangamon county sheriff’s office and has been jailed without bond.
