WICHITA, Kan. (AP) — A Wichita doctor accused of unlawfully distributing prescription drugs has been indicted after a patient died from an overdose.

The U.S. attorney’s office says the 31-count indictment against Dr. Steven R. Henson was unsealed Thursday. The 54-year-old is accused of writing prescriptions for cash, when there wasn’t a medical need and for people other than the ones who came to see him.

Federal prosecutors say the drug scheme resulted in the death of a patient in July. Charges against Henson include unlawfully distributing the painkiller oxycodone, the anti-anxiety drug alprazolam and methadone. Methadone often is used to wean addicts off heroin.

Eight people who got prescriptions from the doctor also are charged with unlawful drug distribution.

Dr Henson’s attorney, Kurt Kerns, didn’t immediately return a phone call from The Associated Press.
