Prosecutors in Tulsa, Oklahoma, have filed first-degree manslaughter charges against the white police officer who fatally shot an unarmed Black man on a city street.

District Attorney Steve Kunzweiler filed the charges Thursday against officer Betty Shelby, who shot and killed 40-year-old Terence Crutcher on Sept. 16. Dashcam and aerial footage of the shooting and its aftermath showed Crutcher walking away from Shelby with his arms in the air.

The footage does not offer a clear view of when Shelby fired the single shot that killed Crutcher. Her attorney has said Crutcher was not following police commands and that Shelby opened fire when the man began to reach into his SUV window.

Tulsa police say Crutcher did not have a gun on him or in his vehicle.

“We will achieve justice in this case,” Jordan said.

Meanwhile, family members and community leaders who have viewed the footage said it clearly shows that Crutcher’s hands were in the air when he was shot.

“We saw that Terence did not have any weapon. Terence did not make any sudden movements. We saw that Terence was not being belligerent,” one of the attorneys for the family, Damario Solomon-Simmons, said at a news conference separate from one police held.

U.S. Attorney Danny C. Williams said the Department of Justice will conduct a separate civil rights investigation into the shooting.
