Authorities raided a major drug production mill in New Jersey linked to 33 overdose deaths, arrested four people and recovered more than $500,000 in drugs stamped with brand names like Dunkin Donuts and Donald Trump, authorities said Tuesday.

Officials seized 70,000 individual doses and an additional four kilograms of suspected fentanyl and heroin as well as two handguns and $165,526 in cash in the takedown of the Irvington drug mill, according to the Attorney General’s Office.

George Encarnacion, 28, of Newark, is accused of running the mill in a second-floor apartment at 214 Eastern Parkway. His alleged associates include Jonathan Perez-Payano, 28, of Newark, and Nelfy Ulerio, 19, of Irvington.

They have been charged with first-degree crimes of maintaining a narcotics production facility and possession of heroin with intent to distribute, as well as a slew of second to fourth degree charges for drug and weapon possession, authorities said.

A fourth person, Steffany Castillo-Candalari, 28, of Newark, faces a second-degree charge of conspiracy to distribute narcotics and lesser charges of receiving stolen property and money laundering, according to the Attorney General’s Office.

A search of Encarnacion’s apartment in Newark recovered $137,000 in cash, five grams of heroin, a scale and packaging materials, authorities said. Perez-Payano and Castillo-Candalari, who lived in an apartment in the same building, allegedly had $28,526, a money counter and a stolen handgun loaded with hollow-point bullets.

From the Irvington apartment, authorities seized the following:

More than 1,400 bricks (consisting of 50 wax folds each) of suspected heroin/fentanyl, plus hundreds of loose wax folds of heroin/fentanyl and empty wax folds

Around four kilograms of suspected fentanyl or fentanyl mixed with heroin

A handgun

Packaging materials and 22 rubber ink stamps bearing different brands, 12 of which have been linked to 93 overdoses, including 33 fatal overdoses and 60 non-fatal overdoses

Authorities have found that a large number of overdose deaths can be traced back to a single source, too often a supplier who mixes fentanyl into heroin. Tracing the stamps in this case allowed investigators to find the mill allegedly responsible for 93 total overdoses, authorities.

Dealers use stamps with memorable names like Dunkin Donuts and Donald Trump to “build their brand” among users, Attorney General Gurbir Grewal said on a a conference call Tuesday morning.

“They’re letting people know they have the most powerful brand on the street,” he said. “They’re very protective of their stamps - it helps promote business for these unscrupulous dealers.”

Grewal also noted that although the bust took place in Irvington, the drugs seized are distributed to a much wider area - throughout New Jersey and into New York, Pennsylvania and other nearby states.

“These doses are supplying more than the demand in the Essex County area. The reach is broader and is going to all corners of our states.”

A similar arrest unfolded in March, when authorities charged 45-year-old Timothy Guest, 45, of Irvington, along with two others for allegedly operating an opioid mill out of a luxury apartment in Harrison. There, they found stamps bearing brand names linked 227 overdoses, including 84 deaths.

"We know that our state is home to far too many people struggling with addiction,” Grewal said. “But we ask that, no matter what challenges you’re facing in your life, if you see heroin stamped with these markings, please, please stay away from it. Your next fix could be your last. If you encounter any of these stamps, please notify law enforcement.”

Encarnacion, Perez-Payano, and Ulerio are being held in the Essex County Jail pending detention hearings scheduled for today. Castillo-Candalari was charged and released.
