Shelby fatally shot 40-year-old Terence Crutcher after his SUV broke down last week.
“We reviewed the facts of the allegations, it is our responsibility to determine if the filing of a criminal charge is justified under the law,” Kurnzweiler said.
An arrest warrant was issued for Shelby and arrangements have been made for her surrender, he said.
Through her attorney Shelby has said Crutcher was behaving strangely and ignoring her commands, and she was afraid that he might be reaching for a weapon.
Multiple police cameras, including ones mounted in squad cars and in a helicopter, captured the Crutcher shooting on tape.
He walks away from Shelby towards his car.
None of the video showed whether the window was open or closed.
There was no weapon found in the car.
