A former Clinton doctor has been sentenced to federal prison on drug charges.

Luis Barrios, 68, a former physician practicing medicine in Clinton, was sentenced today in federal court in Davenport for 18 counts of distribution of a controlled substance not for a legitimate medical purpose and outside the scope of legitimate medical practice, U.S. Attorney Nicholas A. Klinefeldt announced.

The sentencing hearing was held before Judge John A. Jarvey in U.S. District Court for the Southern District of Iowa. Jarvey denied Barrios’s request for a probationary sentence and imposed a sentence of 12 months and 1 day in federal prison followed by two years of supervised release.

On Sept. 10, 2009, an 18-count Indictment was returned against Barrios charging him with distribution of controlled substances: methadone, oxycodone, amphetamine, adderall and hydrocodone, not for a legitimate medical purpose and outside the scope of legitimate medical practice. On June 2, 2011, Barrios entered guilty pleas to all 18 counts. At the sentencing hearing, Jarvey found that Barrios’s conduct was serious because he abused his position as a physician by prescribing drugs to a vulnerable victim and did it repeatedly. Accordingly, Jarvey concluded that a sentence to prison was appropriate.

This case was prosecuted by the U.S. State’s Attorney’s Office for the Southern District of Iowa, and was investigated by the U.S. Drug Enforcement Administration, Office of Diversion Control, and the Clinton Police Department.
