TULSA — Attorneys for former reserve deputy Robert Bates continue to try and reverse his conviction.
We learned Friday that the Oklahoma Court of Criminal Appeals has denied a request to reconsider his conviction.
The 76-year-old was convicted for the fatal shooting of an unarmed black man.
Last month a court upheld his second-degree manslaughter conviction in the April 2015 fatal shooting of 44-year-old Eric Harris.
Bates said he mistook his handgun for his stun gun when Harris was shot during an undercover investigation.
Bates was paroled in October after serving just more than 16 months of a four-year prison sentence.
The appeals court says "no reasonable person" would believe that the use of deadly force was justified in the situation in which Bates shot Harris.
