BRITTON, S.D. (Dakota News Now) – A 31-year-old Britton man has been sentenced to prison for charges involving child pornography.

John Luke Dalstein pled guilty to two counts of possessing, manufacturing or distributing child pornography. He was sentenced to 10 years in prison for each of the counts with five years suspended on each count.

South Dakota Attorney General Marty Jackley and Marshall County State’s Attorney Victor Rapkoch announced that Dalstein was sentenced this week in Marshall County Circuit Court.

The defendant was arrested after a CyberTip was investigated by the state’s Internet Crimes Against Children unit, which is part of the South Dakota Division of Criminal Investigation.

“This investigation is another example of how our ICAC unit protects children from on-line predators,” said Attorney General Jackley.

DCI and ICAC investigated the case, which was prosecuted by the Marshall County State’s Attorney’s Office.
