Ex-deputy who fatally shot Sonya Massey was discharged from the Army for serious misconduct

The Illinois deputy who fatally shot Sonya Massey in her home while responding to her 911 call was discharged from the U.S. Army for “misconduct (serious offense),” according to documents obtained by ABC News.

Sean Grayson, the former Sangamon County sheriff’s deputy, was discharged on February 24, 2016, after beginning service in the U.S. Army on May 5, 2014. He served for a total of one year, nine months and 19 days, Grayson’s certificate of discharge from active duty shows.

The U.S. Army, citing the Privacy Act and Department of Defense policy, said it is prevented from releasing information relating to the misconduct of low-level employees or characterization of service at discharge.

Grayson was a 91B (Wheeled Vehicle Mechanic) in the Regular Army from May 2014 to February 2016. He had no deployments and left the Army in the rank of private first class, according to an Army spokesman.

ABC News has also learned that Grayson, 30, was charged with two DUI offenses in Macoupin County, Illinois, in August 2015 and July 2016, according to court documents.

Grayson pleaded guilty to both charges. He paid over $1,320 in fines and had his vehicle impounded as a result of the 2015 incident. In 2016, Grayson paid over $2,400 in fines, according to court records.

Grayson's attorney, Dan Fultz, declined to comment.

According to employment records, Grayson was hired for his first known police job at the Pawnee Police Department in August 2020 and was fired from his most recent job as a sheriff’s deputy at the Sangamon County Sheriff’s Department after the July 6 deadly shooting of Massey, a 36-year-old unarmed Black woman and mother of two.

Grayson and a second, unnamed deputy responded to Massey’s 911 call reporting a possible intruder at her Springfield home.

Body camera footage released Monday shows Grayson yelling at Massey to put down a pot of boiling water.

The footage, reviewed by ABC News, shows Massey telling the two responding deputies “please don’t hurt me,” once she answered their knocks on her door.

Grayson responded, “I don’t want to hurt you, you called us.”

Later in the video, while inside Massey's home as she searched for her ID, Grayson pointed out a pot of boiling water on her stove and said, “we don’t need a fire while we’re in here."

Massey then poured the water into the sink and told the deputy, "I rebuke you in the name of Jesus."

Grayson threatened to shoot her, and Massey apologized and ducked down behind a counter, covering her face with what appears to be a red oven mitt. She briefly rose, and Grayson shot her three times in the face.

The footage is from the point of view of Grayson’s partner. Grayson did not turn on his own body camera until after the shooting, according to court documents.

A review by Illinois State Police found that Grayson was not justified in his use of deadly force.

Grayson, who is white, has pleaded not guilty to three counts of first-degree murder, aggravated battery with a firearm and official misconduct in Massey’s death.

The news of his discharge and DUI offenses comes days after it was revealed through Illinois Law Enforcement Training and Standards Board (ILETSB) records obtained by ABC News that Grayson worked for six law enforcement agencies over the last four years.

Grayson worked three full-time and three part-time jobs in four police departments and two sheriff’s offices over the past four years, all within the state of Illinois, according to ILETSB records.

Grayson held part-time jobs at the Pawnee Police Department from August 2020 to July 2021, the Kincaid Police Department from February 2021 to May 2021, and the Virden Police Department from May 2021 to December 2021.

He also held full-time jobs at the Auburn Police Department from July 2021 to May 2022, the Logan County Sheriff’s Office from May 2022 to April 2023, and the Sangamon County Sheriff’s Office from May 2023 to July 2024, according to IILETSB records. He moved around all six of these agencies between 2020 and 2024.

“It is clear that the deputy did not act as trained or in accordance with our standards. Therefore, Sean Grayson’s employment with the Sheriff's Office has been terminated,” Sangamon County Sheriff Jack Campbell wrote in a statement last week announcing Grayson’s termination.

The Kincaid Police Department told ABC News that Grayson was let go due to his refusal to live within 10 miles of Kincaid Village. They also said there were no allegations of wrongdoing against Grayson during his time with the department.

According to documents obtained by ABC News, Grayson left his part-time employment at the Pawnee Police Department to pursue a full-time position at the Auburn Police Department. His application to Pawnee Police Department also states that he had previously worked as security guard at Hospital Sisters Health System St. John's Hospital in Springfield, Illinois.

ABC News has reached out to the other police departments to learn why Grayson left, but has not yet received a response.
