 A crooked doctor is going to prison, Michael Board reports. A federal jury has convicted an Oklahoma City doctor of stealing large amounts of controlled drugs that he claimed were for patient surgeries, but instead he kept them for his own personal purposes. 35-year-old Dr. John Nedsta of Edmond worked as a contract anesthesiologist. Some of the drugs he diverted included fentanyl, ketamine, and midazolam. He faces up to 70 years in prison when he's sentenced in about 90 days.
