WOODBURY - Authorities say two Long Island pharmacists are among four suspected leaders of a massive black market drug ring that scammed the federal government out of millions of dollars. State prosecutors say Glen Schabel, the supervisor of Moms Pharmacy in Melville, took bribes to purchase more than $274 million worth of black market HIV medications back in 2008. Another pharmacist, Ira Gross, of Babylon, is accused of brokering the deal. Moms Pharmacy then dispensed the illegally obtained drugs to HIV patients and billed Medicaid for the medication, authorities say. Prosecutors say the scheme endangered HIV patients by exposing them to drugs of unknown origin and potency. In some cases, the drugs were mislabeled or potentially expired. The two pharmacists are accused of pocketing approximately $26 million in the crime. All four defendants are facing a slew of felony charges, including grand larceny, money laundering and bribery. A spokesperson for Moms Pharmacy says it is cooperating with authorities in the investigation.
