Cops still don’t definitively know if the powder discovered near the 33-year-old beauty was heroin, cocaine, fentanyl or a deadly cocktail of all three.

Police had been searching for the dealers in the area who may have sold the drugs believed to have killed Nolan.

These dealers] may or may not have known [they were selling] poison to this girl, but that doesn’t matter,” a source told The Post in August.

“With higher-profile cases like this poor girl in Montauk, you’re going to see more and more of these dealers getting locked up,” the source said.

Prosecutors could “seek manslaughter or [criminally negligent] homicide charges” against the drug peddlers, the same source said. “There’s a slew of possession and trafficking charges, and they could decide to get [federal authorities] involved, which would mean more time in prison if these bastards are convicted.”

The lack of details surrounding Nolan’s death is “frustrating” for her loved ones, family lawyer Arthur L. Aidala told The Post Friday, especially since they’ve not seen a full toxicology report or been given her final cause of death.

“But we know the effort is being made by the DA’s office to do what needs to be done to cross every ‘t’ and dot every ‘i’ to get to the bottom of this,” he added.

He also pushed back against speculation that the Irish designer overdosed, insisting that Nolan wasn’t known to do drugs.

“Something doesn’t make sense here,” Aidala charged. “But we’re hanging back and letting law enforcement do their job.”

Police have denied The Post’s legal request for public documents related to her autopsy and toxicology reports, claiming they are “restricted to specific entities.”
