A former ski instructor at a Tahoe resort has drawn a 15 year prison term, for the sexual exploitation of a minor. Judge Howard McKibben also said during the sentencing hearing in Reno Wednesday that 26 year old Stephan DeGraffenreid of Gardnerville will be supervised as a sex offender for life. He could have faced up to 45 years in prison. DeGraffenreid had been fired from his job as an assistant at the Heavenly Ski Resort before his March arrest. Degraffenreid was caught after his cellphone was found at the resort, filled with nude photos toddlers he apparently downloaded from the internet. He had also photographed toddlers in a bathroom at a rural church daycare center.
