An Alaska nurse practitioner and a doctor dubbed “the Candy Man” were charged Wednesday with providing millions of opioid doses to patients who did not medically require the drugs, which in turn fueled addiction and caused overdoses and deaths, officials said.

The Alaska U.S. attorney said 48-year-old Jessica Joyce Spayd and 74-year-old Lavern Davidhizar were arrested and charged separately for distributing the prescription painkillers. Federal prosecutors said the two medical professionals helped fuel the state’s opioid epidemic.

Spayd, an advanced nurse practitioner and owner of Eagle River Wellness in Eagle River, was charged with distribution of narcotic substances resulting in death. Davidhizar, a physician at Family Medical Clinic in Soldotna, was charged with distribution of a scheduled controlled substance.
