DETROIT – Four doctors, two nurse practitioners and three pharmacists are among the 19 people who have been indicted in connection with an elaborate drug scheme that went on for years, officials said. The opioid epidemic is still very much a problem in Metro Detroit, with people addicted to and dying from pain pills, heroin and fentanyl. Oxycodone, Percocet and hydrocodone are powerful pain pills that were pedaled on the streets for cash. “These people are greedy and they don’t care about the average citizen,” said Steve Dolunt, the former assistant Detroit police chief. “Average people, some people, have pain,” Dolunt said.
