The five year prison sentence will run concurrently with a 25-year sentence he’s already serving for drug trafficking crimes. A jury in November found Schultz guilty of prescribing as many as 20,000 narcotics pills to patients who came to his office complaining of pain.

Schultz is appealing his November conviction on the drug charges, while prosecutors are appealing his sentence for that conviction.
