Dist. Ct. did not err in imposing 70-year term of incarceration after defendant pleaded guilty to several counts of manufacturing and possession of child pornography that included pictures of defendant’s 5-year old and 2-year old children. While defendant argued that Dist. Ct. improperly determined that he was likely to recidivate for rest of his life, Dist. Ct. could properly conclude that defendant posed risk of future crimes that supported imposition of lengthy sentence. Moreover, instant sentence was substantively reasonable where maximum sentence was 130 years, and where circumstances indicated that defendant molested his children and posted said pictures on internet.
