Following a preliminary hearing last Wednesday in Leaven-worth County District Court, Pfannenstiel pleaded not guilty to the charges and to a charge of bringing contraband into the prison. In August, authorities leveled two sex charges against Pfannenstiel, 38, a former sergeant at Lansing Correc-tional Facility. The third charge was added Wednesday before the hearing. At the hearing, a prison investigator and three inmates testified about alleged sexual encounters between the inmates and Pfannenstiel. The mayor did not testify.

After the hearing, District Judge Frederick N. Stewart set a pretrial conference for Oct. 27.
