The Oklahoma police officer who shot an unarmed black man last year was found not guilty of manslaughter by a jury late Wednesday.

Tulsa Officer Betty Shelby had testified in her own defense after the Sept. 16 fatal shooting of 40-year-old Terence Crutcher.

The Tulsa County district attorney charged Shelby with one count of first-degree manslaughter. Shelby pleaded not guilty.

Officers who had responded to a call said they found Crutcher acting oddly. Shelby said she responded with gunfire when he reached into his car for what she thought was a weapon. Crutcher's family and attorney said his car windows had been rolled up at the time of the incident.

Following Crutcher's shooting, officers confirmed he did not have a gun in the vehicle.

The verdict comes at a time when police shootings of unarmed African-Americans has been widely criticized as unwarranted.
