A group of seven men has been arrested and indicted on 39 counts of selling “massive quantities” of fentanyl, heroin, and cocaine on Staten Island via an organized, multi-borough criminal network, the borough’s District Attorney Michael McMahon and Police Commissioner Jessica Tisch said Thursday. “We are ensuring that these predatory defendants will no longer victimize innocent Staten Islanders in the throes of addiction illness.” The district attorney’s office says the investigation was initiated after a series of fatal overdoses occurred in the Great Kills and Eltingville neighborhoods of Staten Island. “After multiple fatal overdoses on Staten Island, our investigators did what they do best: got to work and identified those responsible for harming our communities,” said Tisch. “We will not allow drug traffickers to flood our neighborhoods with these dangerous narcotics without consequence.”
