TOMS RIVER — Investigators busted two drug trafficking networks that were importing more than $300,000 worth of heroin into the county each week, seizing guns and more than a dozen vehicles, authorities.

Police charged 36 people during the two operations, dubbed by law enforcement as "Sin City" and "Broken Rule," and seized nearly 31,000 dosage units of heroin, approximately 25 grams of raw heroin, $140,000 in cash, 14 vehicles, six firearms, including a TEC-9 assault weapon, and materials used to produce drugs, Ocean County Prosecutor Joseph Coronato said in a release.

"These simultaneous operations are incredible investigative feats," Coronato said. "Beyond the approximate street value of over $325,000 in heroin seized during operations "Broken Rule" and "Sin City", this outstanding Law Enforcement partnership has extended the reach and effectiveness of Ocean County law enforcement far beyond our borders."

In Operation Sin City, investigators discovered Jonathan Gonzalez, 32, also known as "Sin," of Pleasantville and Toms River, was managing and directing a heroin distribution network in Ocean and Atlantic counties, Coronato said. The drug ring was importing pre-packaged and uncut heroin to Ocean County for distribution.

Investigators found locations in Toms River where Gonzalez and other members in his network would prepare the heroin, the prosecutor said.

Detectives from the county's Special Operations Group had Gonzalez, Faythe Darling, 29, of Toms River, and Miasia Johnson, 21, of Barnegat, under surveillance in the evening hours of April 23 as they returned from Philadelphia with uncut heroin and packaging material, Coronato said. Investigators pulled over a vehicle they were driving in the area of Route 70 and Route 539 in Manchester and all three were arrested on drug charges.

While the car stop was going on, other Special Operations Group members and partnering law enforcement agencies served search warrants in Toms River, Barnegat, South Toms River, Brick Township and Pleasantville, Coronato said. Approximately 25 grams of raw heroin, an undisclosed number of pre-packaged heroin, cash and packaging material were seized, along with four vehicles that were used in the drug distribution network.

In a separate investigation, dubbed Operation Broken Rule, a father and son were arrested for allegedly importing heroin from Elizabeth to Ocean County, Coronato said.

During the evening hours of March 31, an investigation led Special Operations Group detectives along with members of the Union County Prosecutor's Office Narcotics Task Force and the Elizabeth Police Department to a mall in Elizabeth, Coronato said. Bertrick Artis, 45, known as "King Rule," his son Ashzon Artis, 25, and Angelique Morris, 23, of Tinton Falls, were trying to buy heroin from two Bronx, New York men, Javier Cruz, 25, and Kennin Chavez, 19.

While the arrests were happening, investigators served search warrants in Lakewood, Toms River, Lakehurst, Barnegat, the Waretown section of Ocean Township and Jackson, Coronato said.

Large amounts of heroin, cash, illegal weapons, including an assault-style firearm, and drug packaging material were seized, Coronato said. Ten vehicles used in the distribution network were also seized.

The two networks were importing more than a kilogram of heroin, or 50,000 doses of the drug, to Ocean County each week, authorities said. Heroin typically sells for $3 to $8 per dose, depending on the dealer and customer.

The investigation is ongoing and additional arrests are expected, Coronato said.
