(Stillwater, Okla.) – A convicted killer serving a 25-year sentence for a fatal stabbing in Logan County in 2016 has been given an additional two-year prison term for hitting a detention officer while he was being held in the Payne County Jail in 2017.
    Michael Ray Chisholm, 32, of Oklahoma City, who has a seventh grade education, pleaded guilty Friday to assault and battery on a Payne County detention officer, court records show.
    According to an affidavit by Payne County Detention Deputy Thomas Harders, on March 23, 2017, jailers “were conducting a shakedown of A-Pod due to a ‘shank,’ referring to a home-made knife, being found earlier in the day.
    “While performing the shakedown, Inmate Chisholm became very agitated and aggressive towards the staff members conducting the search,” the affidavit said.
    A detention officer, who was struck in the eye, told Harders, “We were leaving the cell when (he) started stirring himself up and yelling at us. I went back to the cell to talk to him and try to calm him down.
    “I opened the cell door to speak with him face to face. While I was speaking with him, he hit me in the eye. I pushed him back to the back wall of the cell using strikes to attempt to gain control of him,” as other detention officers arrived to assist, the affidavit said.
    The officer, who was injured, had broken blood vessels in his left eye and bruising to the eye and nose region, for which he was treated at the Stillwater Medical Center emergency room, the affidavit said.
    According to Oklahoma Department of Corrections records, Chisholm has been convicted of:
    * second-degree murder for a fatal stabbing in 2016 in Logan County for which he was given a 25-year prison term in October 2017;
    * methamphetamine possession in 2014 in Oklahoma County for which he was originally given probation that was subsequently changed to a 10-year prison term;
    * cocaine possession in 2008 in Oklahoma County for which he was given a two-year prison term in 2013, of which he served about nine months;
    * stolen property possession in 2009 in Oklahoma County for which he was originally given probation that was charged to a two-year prison term in 2014, of which he served about 8 months;
    * domestic violence in 2013 in Oklahoma County for which he was given a two-year prison term in 2014, of which he served about 11 months;
    * uttering forged instruments in 2010 in Cleveland County for which he was given a five-year prison term of which he served less than two years.
