It was the largest gang takedown in Bronx history – and detectives from the Wareham Police Department played a key role.

The takedown, the news of which broke March 11, resulted in 84 indictments of New York crew members charged with violent crimes, weapons, and drug trafficking violations, with 31 people arrested March 9, the Bronx County District Attorney’s office said.

Bronx District Attorney's office spokeswoman Patrice O'Shaughnessy said the takedown is related to the stabbing of crew member Moises Mojica in the Silver Lake Motel on Nov. 4, 2014, and that 13 of the 84 crew members were charged with conspiracy to distribute in Wareham and Bourne. She said the crew members stopped coming to the area as frequently in late 2014, following the stabbing, according to the prosecutor on the stabbing case.

"[The prosecutor] said the local dealers ... were angry because these guys were having success [selling drugs]," O'Shaughnessy said. "After that, they got nervous about selling there, and turned their sights to New Hampshire."

The attorney’s office said that in February 2015, it was found that crew members had been frequenting Wareham and Bourne, possibly to sell narcotics. In May, it was confirmed that the crew had been transporting heroin and cocaine from the Bronx to the Wareham and Bourne areas from 2012 until late 2014.

New York Drug Enforcement Agency Associate Special Agent Keith Kruskall who headed the strike force that helped make the arrests on March 9 said they began the investigation in Wareham and Bourne by "looking historically at ... phone calls, jailhouse calls, Western union transactions," and following leads from confidential sources.

"The strike force went up twice and met with [the Wareham and Bourne] police departments," Kruskall said. "They gave us intel on the targets from the Bronx, and some additional targets."

The investigation began in November 2014, when police in New York's 44th precinct began working with the New York District Attorney’s office to investigate street crews based in the 44th and 46th precincts thought to be responsible for shootings.

It was found that the crew members had been sending crack cocaine and, to a lesser extent, heroin to Manchester, New Hampshire. They were selling crack cocaine for $10,000 per week in New Hampshire, and bringing firearms from New Hampshire to the Bronx.

Wareham Police Chief Kevin Walsh said that though a few crew members were found in Wareham as recently as February of this year, they have not been coming through the area regularly since 2014.

Because the investigation is ongoing, and police are still in the process of testifying before a Grand Jury in New York City, Walsh said he cannot give more details of the Wareham Police Department's involvement at this time. However, he said is he "very proud" of the town's four detectives, and that the collaboration among the Wareham, Bourne, and Bronx police departments have created a "major chink" in drug trafficking on the Cape.

"We always say we are trying to make a dent," Walsh said. "It doesn't end all our problems, but we don't have our feet up. I am very proud we have an aggressive unit that is cooperating with everybody."

The Bronx District Attorney’s office said search warrants of the suppliers in the 46th precinct, as well as Manhattan and Bergen County, N.J., yielded nine kilograms of cocaine, four kilograms of heroin, two kilograms of the synthetic opiate Fentanyl, half a kilogram of heroin laced with Fentanyl, and 12 pounds of cutting agents. The police also seized about $260,000 in cash, seven vehicles, and 889 grams of crack cocaine. They also found 15 firearms and hundreds of rounds of ammunition.
