STATEN ISLAND, New York (WABC) -- Two brothers are among nine people arrested and charged in connection with a drug ring involving heroin and oxycodone on Staten Island Wednesday.The U.S. Attorney's Office said eight people were arrested on Staten Island and Brooklyn, and the other was picked up in Arizona.Prosecutors said the arrests came from a long-term investigation into heroin and oxycodone trafficking on Staten Island. The investigation started after a confidential source worked with law enforcement to buy heroin from Michael Calabria, who is charged in the case."These defendants allegedly pushed heroin and oxycodone for months, contributing to the opioid plague that has caused great suffering on Staten Island," United States Attorney Robert Capers said.****The investigation was a joint effort by federal and local law enforcement agencies."As alleged, these individuals distributed heroin and oxycodone in their own community, and by doing so they endangered the lives of those who live and work around them by contributing to the supply of highly addictive narcotics that have led to numerous overdoses and deaths," NYPD Police Commissioner James O'Neill said. "The NYPD is committed to holding accountable those who are responsible for this deadly flow of poison and ensuring they are brought to justice."Prosecutors said the ring sold heroin and/or oxycodone from September 2016 to January 2017.MICHAEL CALABRIAAge: 49Staten Island, NYJOSEPH CALABRIAAge: 52Staten Island, NYSTEPHEN DELPRIOREAge: 55Staten Island, NYDEVIDA LOMBARDOAge: 46Staten Island, NYUGO GALLOAge: 46Staten Island, NYCAROL MONFORTEAge: 57Staten Island, NYVINCENT MANISCALCOAge: 55Brooklyn, NYGLENN DEPAOLOAge: 59Staten Island, NYMARIA DEPAOLOAge: 55Staten Island, NYThe DEA said there the number of fatalities associated with heroin and oxycodone drug overdoses in New York City over the past five years has skyrocketed.
