Prosecutor Peter Kougasian focused on the death of one patient, Joseph Hague, who saw Dr. Stan Li for less than a year before he died.
The doctor is charged with manslaughter, criminally negligent homicide and criminal sale and possession of narcotics.
A patient testified Monday that Dr. Stan Li prescribed him half a dozen powerful medications at once and showed no concern when he complained about side effects.
A Queens doctor ran his office like a popular deli, where up to 100 patients a day would take numbers, wait their turn and then pay cash for painkiller prescriptions, a former receptionist at the clinic testified Wednesday.
Opening statements began Wednesday in Stan Li’s case. A narcotics prosecutor portrayed him as a drug dealer with a medical degree.
The charges were announced in an indictment Thursday against 58-year-old Stan Li.
