Officials: Tulsa police officer "reacted unreasonably," charges filed in Terence Crutcher shooting

TULSA, Okla. — Quick Facts:

The Tulsa County District Attorney filed first degree manslaughter charges against Officer Betty Shelby with the Tulsa Police Department.

Shelby shot and killed Terence Crutcher on Sept. 16 in north Tulsa. Video released showed Crutcher with his hands up.

Tulsa County DA Steve Kunzweiller said a warrant was issued for Shelby's arrest and arrangements are being made with her lawyer to turn herself in to authorities.

From the affidavit:

"Your affiant feels that Officer Shelby reacted unreasonably by escalating the situation from a confrontation with Mr. Crutcher, who was not responding to verbal commands and was walking away from her with his hands held up, becoming emotionally involved to the point that she overreacted."

Mayor Dewey Bartlett released a statement shortly after Kunzweiler's announcements:

Our Tulsa Police Department worked quickly to provide all the information to the District Attorney. I appreciate their efforts as well as the District Attorney’s usual thorough evaluation of the rules of law for which we are all accountable. These are important steps to ensure that justice and accountability prevails.

We will continue to be transparent and ensure the system carries out its responsibility to provide justice.

We also appreciate the expedited work by Governor Mary Fallin and the State Medical Examiner’s office.

Whether through peaceful demonstrations, prayer vigils or countless statements of support to the Crutcher family and the entire community, we are in this together as one Tulsa. We continue to pray together, mourn together and we will get through this together.

Shelby's attorney told FOX23 she is out of town due to death threats and will not turn herself in Thursday night.
