Courtland Samuel Clark, 21, Minot Air Force Base, was sentenced on Monday to five years in prison, with all suspended but six months, and three years of supervised probation, for Class C felony possession of child pornography.

North Central District Court Judge Todd Cresap also ordered Clark to register as a sex offender and to pay $525 in court costs. Two cell phones that Clark used to download and view the child sex abuse material were ordered destroyed.

Clark will serve his six-month sentence in the Ward County Jail. Ward County Assistant State’s Attorney Tiffany Sorgen told the judge that prosecutors believe Clark will actually end up serving more of his sentence at the county jail than he would if he were sent to the state penitentiary, which has typically released inmates early.

The sentence was part of a plea deal worked out between the prosecution and the defense. Clark’s defense attorney, Erich Grant, told the judge that Clark was only 18 at the time of the offense and studies show that the frontal lobe of the brain continues to develop until about the mid-twenties. Grant said Clark was in possession of a limited number of images. A pre-trial investigation showed no real cause for concern.

Clark was recently discharged from the U.S. Air Force after he entered his guilty plea, according to statements made in court.
