The doctor is accused of writing fraudulent prescriptions from her office on West 127th Street. The other suspects then sold the drugs, including the painkiller OxyContin.
Prosecutors say Dr. Diana Williamson was receiving Medicaid funding for the drugs. Her office was searched by federal investigators Thursday morning.
The defendants each are charged with one count of conspiracy to distribute and possess with the intent to distribute a controlled substance, which carries a maximum penalty of 20 years in prison and maximum fine of $1,000,000.
Williamson, co-defendant Lenny Hernandez (who reportedly recruited people to get the prescriptions from the doctor) and two others are also charged with one count of conspiracy to commit health care fraud, which carries a maximum penalty of 20 years in prison and a maximum fine of $250,000.
