A prison counselor on Tuesday pleaded guilty in Livingston County Circuit Court to a charge of sexual conduct with a prisoner or offender.

 In exchange for John Thomas Dunn’s guilty plea, the prosecutor recommended four years in the Department of Corrections with a suspended execution of sentence. Sentencing has yet to be decided pending a sentencing assessment. Charges of sexual conduct with a prisoner, and sodomy were filed in fall 2017 against Dunn, 66, who had been employed with Corizon Health, a company with which the Missouri Department of Corrections contracts to provide medical and mental health care. The department has contracted with Corizon for more than 20 years, according to Karen Pojmann, the department’s communications director. On Tuesday, the prosecutor dismissed the sodomy charge. Chillicothe Police Detective Jon Maples investigated the case and filed a report with Livingston County Prosecuting Attorney Adam Warren in October 2017. The report states that the police department was contacted around 3:30 p.m. Sept. 22, in reference to a sexual assault by an employee of the correctional center to an offender at the center. The offender’s statement provides details into the alleged events that took place between she and Dunn. The report states that the correctional center offender said that “verbal stuff” started between she and Dunn long ago and that he had been her therapist for about five years. She stated that the physical contact probably started around Sept. 5. There are approximately 1,340 female offenders housed at Chillicothe Correctional Center.
