A Chantilly pain clinic owner was convicted in a federal court Thursday on drug trafficking and fraud charges. A nurse practitioner at the clinic was also convicted of distributing oxycodone.

Paul Boccone, 56, the owner and president at the Chantilly Specialists pain clinic, was convicted of conspiring to distribute and distribution of oxycodone, healthcare fraud and payroll tax evasion. 

Charles Brown, Jr., 51, a nurse practitioner with the clinic, was convicted of conspiring to distribute and distribution of oxycodone.

The verdict was handed down in the courtroom of District Judge Claude M. Hilton. 

Prosecutors said that Boccone treated patients and prescribed narcotics by either forging the signatures of medical practitioners, or encouraging medical practitioners to endorse prescriptions that he wrote.

Brown, the lead medical practitioner at the clinic, prescribed large amounts of narcotics to patients who didn't need it, prosecutors said. 

Boccone, the clinic owner, faces a maximum sentence of 350 years in prison. Brown, the nurse practitioner, faces up to 160 years in prison.
