Dr. Paul Volkman operated pill mills in Chillicothe and Portsmouth
(AP) A federal judge in Ohio has sentenced an Illinois doctor to four life terms following his conviction in the drug overdose deaths of four patients.
Federal prosecutors say Dr. Paul Volkman dispensed more of the painkiller oxycodone from 2003 to 2005 than any other physician in the country.
U.S. District Court Judge Sandra Beckwith imposed the sentences Tuesday in Cincinnati, along with sentences ranging from 10 to 20 years on 13 other drug-trafficking related counts.
Prosecutors say Volkman made weekly trips from Chicago to three locations in Portsmouth and one in Chillicothe before federal investigators shut down the operations in 2006.
The 64-year-old Volkman maintains his innocence and had demanded the judge release him immediately.
