The Latest on an Oklahoma police officer's fatal shooting of an unarmed black man (all times local):

5:35 a.m.

An Oklahoma police officer charged with manslaughter in last week's shooting death of an unarmed black man has surrendered to authorities.

Tulsa County jail records show that 42-year-old Betty Shelby turned herself in early Friday, hours after prosecutors charged her with first-degree manslaughter in the death of Terence Crutcher.

The records show Shelby, who is white, was booked at 1:11 a.m. and released at 1:31 a.m. after posting $50,000 bond.

District Attorney Steve Kunzweiler filed the charges Thursday afternoon against Shelby, saying the officer "reacted unreasonably" when she shot Crutcher, who did not have a gun.

1:30 a.m.

Less than a week after an unarmed black man was shot dead by a white police officer on a Tulsa street, prosecutors charged the officer with first-degree manslaughter.

That decision that may prevent unrest in a city with a long history of tense race relations.

Prosecutors wrote in an affidavit filed with the charge on Thursday that Tulsa officer Betty Shelby "reacted unreasonably" when she fatally shot 40-year-old Terence Crutcher on Sept. 16.

Phil Turner, a Chicago-based defense attorney and former federal prosecutor, says that in acting quickly, prosecutors may partly have wanted to allay outrage in the city and avoid the kind of violent protests Charlotte, North Carolina, has seen over another recent police shooting of a black man.
