The Ministry of Justice has launched an investigation into the murder of Sonia Messi by the police

SPRINGFIELD, Ill. (AP) – The U.S. Justice Department is seeking documents related to the shooting death of an Illinois woman in her home by a sheriff’s deputy as it investigates local authorities’ treatment of black residents and people with disabilities.

The government listed the demands in dozens of categories in a letter to the Sangamon County Sheriff’s Office dated Thursday.

“The Sheriff’s Office, along with the county agencies involved, is participating in the discussion and is committed to fully cooperating with the Department of Justice in its review,” Sheriff Paula Crouch said Friday.

Sonya Massey, a 36-year-old black woman, was killed in July when deputies responded to a call about a possible robbery at her home in Springfield, Illinois. She was shot three times during the struggle with the officer.

Sean Grayson, who is white, was fired. He has been charged with murder and other crimes and has pleaded not guilty.

The Justice Department wants to know if the sheriff’s office has strategies for responding to people in “behavioral health crises,” among many other requests.

“This incident raises serious concerns about … interactions with black people and people with mental health problems,” the government said.

Andy Van Meter, chairman of the Sangamon County Board, said the DOJ review is an important step in building public confidence in the sheriff’s office.
