Dark Web Narcotics Vendor: "Mamaknowsbrown" Pleads Guilty

#Dark Web Narcotics Vendor: "Mamaknowsbrown" Pleads Guilty

#The Case

Carolyn Tolin, aka "Mamaknowsbrown," a 46-year-old woman from Centereach, New York, has pleaded guilty to running a large-scale narcotics operation on the dark web. Her vendor site, MamaKnowsBrown, offered a range of narcotics to customers nationwide.

#The Operation

Tolin's operation utilized standard practices common in the dark web marketplaces, including various shipping methods such as the USPS, UPS, and notably, same-day delivery via Uber. This convenient service allowed customers to receive their orders quickly, often within hours of placing an order. To facilitate this rapid delivery, Tolin would use Uber drivers to transport packages directly to customers, often using encrypted communication to coordinate the logistics.

Each package included an overdose-warning card, which Tolin personally created. The card advised customers to keep Narcan nearby, not to use the substances alone, and warned that her batches were extremely potent and intended only for "experienced" users.

#The Bust

On March 14, 2025, law enforcement executed a search warrant at Tolin's residence, recovering large quantities of narcotics, including fentanyl, heroin, and cocaine, as well as computer equipment, packaging materials, heat sealers, scales, envelopes, and packages. Tolin was arrested and has been in custody since.

#The Charges and Sentence

Tolin pleaded guilty to one count of Criminal Possession of a Controlled Substance in the First Degree and one count of Attempted Operating as a Major Trafficker on November 20, 2025. She faces:

• Up to 15 years in prison
• 5 years of post-release supervision

#The Investigation and Prosecution

The case was investigated by the Suffolk County Sheriff's Office and the Suffolk County District Attorney's Fentanyl Task Force, and prosecuted by Assistant District Attorneys Kristin Barnes and Matthew Laube.

#Key Facts

• Tolin's operation sold over $75,000 worth of narcotics between September 2024 and March 2025.
• The operation used various shipping methods, including the USPS, UPS, and Uber.
• Tolin included overdose warning cards with each package, detailing the potency and danger of the narcotics.

Tolin's dark-web shop “MamaKnowsBrown” had “tip jar” add-ons and shipped more than 1,000 drug packages to 40 states.

#What's Next

Tolin is due back in court on January 8, 2026, and is being represented by Ian Fitzgerald, Esq. The case highlights the ongoing efforts of law enforcement agencies to combat narcotics trafficking and the importance of holding individuals accountable for their role in these crimes.
