A 25-year-old Centereach man who authorities said impersonated doctors, dentists and other prescribers to fraudulently obtain prescription medications pleaded not guilty to a 90-count indictment Tuesday.
Matthew DelPesce of 1 Gaynor Rd. was arraigned on the grand jury indictment before State Supreme Court Justice William Condon.
Among the charges are criminal possession of a controlled substance, falsifying business records, possession of a forged instrument, criminal impersonation, and misdemeanor fraud and deceit.
DelPesce was being held in county jail in lieu of $100,000 cash bail.
In a statement, Suffolk District Attorney Thomas Spota said a months-long investigation by State Police and district attorney's investigators found DelPesce "illegally acquired oxycodone and other opiates from five pharmacies" in April and May. Those pharmacies are located in Centereach, Port Jefferson Station, Commack and Deer Park.
"We found ample evidence following the execution of a search warrant at the defendant's house that DelPesce frequented emergency rooms, the offices of immediate care physicians and others with one objective -- to secure a prescription and the unique identifying physicians' credentials to prescribe controlled substances," Spota said in a prepared statement.
