An Oklahoma sheriff's agency where a reserve deputy fatally shot an unarmed man has found what it calls deficiencies in files of about 50 of its 128 reserve ranks, though the bulk are considered clerical in nature.
Tulsa County Sheriff's Office reserve coordinator Justin Green said Thursday many of the faults were minor, such as outdated driver's licenses or missing training certificates.
Green declined to release the review's findings, saying it was considered an ongoing investigation.
The agency's reserve deputy program has been suspended since volunteer deputy Robert Bates fatally shot a man in April. Bates, who left the agency, says he confused his handgun for a Taser and has pleaded not guilty to second-degree manslaughter.
A grand jury is also looking into allegations of wrongdoing at the agency.
