A new trial date has been set for a former Oklahoma volunteer deputy charged with second-degree manslaughter in the fatal shooting of an unarmed man.

Former Tulsa County Sheriff's Office volunteer deputy Robert Bates will go to trial April 18.

Bates was initially set for trial in February, but two judges initially assigned to preside over the trial withdrew from the case.

The case was transferred to District Judge Bill Musseman, who set the new trial date at a hearing Wednesday.

Bates is accused of fatally shooting Eric Harris in a Tulsa street in April. Bates has pleaded not guilty and says he confused his handgun and stun gun.

The shooting led to a grand jury investigation of the sheriff's office and the indictment of ex-sheriff Stanley Glanz.
