The former administrator of the McClain County jail was sentenced Wednesday to 51 months in federal prison in the 2013 death of a diabetic inmate.

"My actions should have been better than what they were, and for that, I'm truly sorry," Wayne Evans Barnes told an Oklahoma City federal judge during the sentencing.

Barnes, 56, of Norman, admitted he violated the civil rights of the inmate, Kory Dane Wilson, who needed insulin to control his Type 1 diabetes. He admitted he failed to obtain medical assistance for Wilson after being alerted of the inmate's condition.

"I live every day for Kory Wilson," Barnes told the judge. "Sincerely, his death has changed my life. ... I'm in pain all the time."
