INDIANAPOLIS, Ind. (AP): Prosecutors have filed reckless homicide charges against an Indiana doctor in the deaths of three patients.

The criminal counts announced Friday by the Marion County prosecutor's office charge that Dr. John Sturman overprescribed narcotics for pain that resulted in the deaths. The patients died in 2010 and 2011, but aren't identified in court records. The prosecutor's office says Sturman was jailed in Danville, Illinois, pending extradition to Indianapolis. It wasn't immediately clear whether Sturman has an attorney or whether he was practicing medicine in Illinois.

The prosecutor's office says Sturman operated a clinic at Indiana University Hospital in Indianapolis, but lost his admitting privileges in 2012 after he failed to complete medical charting and documentation of patient visits. 

Sturman also faces 16 counts of improperly prescribing drugs.
