A former Oklahoma volunteer sheriff's deputy who said he mistook his handgun for his stun gun when he fatally shot an unarmed suspect last year was convicted of second-degree manslaughter on Wednesday, reports the Associated Press .
Jurors handed down the verdict in the case of 74-year-old Robert Bates, a wealthy insurance executive accused of fatally shooting Eric Harris while working with Tulsa County sheriff's deputies last year during an illegal gun sales sting. Harris, who had run from deputies, was restrained and unarmed when he was shot.
