REED CITY - Evart High School Principal Alan Kullman is charged with three counts of first-degree criminal sexual conduct with a 14-year-old female student, but police are investigating the possible involvement of other victims. Kullman was arraigned on charges Thursday in Osceola County's 77th District Court. The first-degree criminal sexual conduct charge specifies that the suspect had a position of authority over the victim, said Michigan State Police Det. Sgt. Gary Green. The statute also applies to victims between the ages of 13 and 16. Kullman's request for bond was denied because police believe he is a flight risk. Prior to his arrest on Tuesday, Kullman was staying with relatives outside of Osceola County. If convicted, Kullman could be sentenced to life in prison and would be required to register on the Michigan Sex Offender Registry. Police are investigating a few names of other potential victims, Green said. Anyone with additional information on this case is asked to call the Mount Pleasant post at (989) 773-5951. Green declined to comment on how the relationship began between Kullman and the student or about the possibility of text messages being exchanged between Kullman and the victim. He said the relationship has been going on "for several months" before the initial report was made. "A concerned parent contacted the Evart Police Department and they began an investigation into some allegations of an inappropriate relationship with a student," Green said. "Once their investigation began, they realized it was outside their jurisdiction so they contacted the State Police. We began our investigation on June 2." Kullman asked for a leave of absence on May 29. Following the arraignment, Evart Public School district superintendent Howard Hyde gave a statement to the media, saying: "I attended the arraignment today and was shocked and extremely disappointed to hear the charges. I had no knowledge of this type of conduct. The safety of our students is always our top concern. I have faith in the legal system and will wait for the outcome of this case. At that time, any necessary steps will be taken pending the results of the case." Kullman will have a pretrial conference with his attorney on Thursday. He is tentatively scheduled to appear for a preliminary examination at 1:30 p.m. June 21.
