TULSA, Okla. (AP) — An examination of records from the past two years shows that 40 jailers in the Oklahoma prison system have been fired for rules violations.

The Tulsa World reported Sunday that (http://is.gd/4DOxUe ) the Department of Correction has disciplined more than 130 employees between 2009 and mid-2011 for a wide range of offenses.

One of the most extreme examples of allowing unauthorized inmate behavior was found at Howard McLeod Correctional Center. Officials learned a prison guard had allowed inmates at the minimum-security prison to hunt wild hogs and butcher them.

The guard was suspended for a day. The hogs were trapped, not shot, and officials say the hunt didn't pose a risk to public safety.
