Tulsa, Okla. (AP) - 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.
