The Justice Department is launching an investigation into the police shooting of Sonya Massey

SPRINGFIELD, Ill. (AP) — The U.S. Justice Department is demanding records in the shooting of an Illinois woman who was killed in her home by a sheriff’s deputy as it investigates how local authorities treat Black residents and people with behavioral health problems.

The government issued a list of demands in dozens of categories in a letter to the Sangamon County Sheriff’s Office on Thursday.

“The Sheriff’s Office, along with appropriate county agencies, has engaged in discussions and pledged full cooperation 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 officers responded to a call about a possible prowler at her home in Springfield, Illinois. She was shot three times during a confrontation with an officer.

Sean Grayson, who is white, was fired. He is accused of murder and other crimes and has pleaded not guilty.

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

“The incident raises serious concerns about… interactions with black people and people with behavioral health conditions,” the government said.

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