A Long Island woman has pleaded guilty to operating a large-scale online narcotics business from her Centereach garage, prosecutors said Thursday.
Carolyn Tolin, 46, admitted to selling heroin, fentanyl, crack and powder cocaine through her dark-web vendor site, “MamaKnowsBrown,” to customers on Long Island and across the country, the Suffolk County District Attorney’s Office said in a news release.
After placing an order through her site, customers paid Tolin in cryptocurrency, which was then converted to cash, investigators said. Tolin used Uber to deliver orders to local customers, while those outside Suffolk County received shipments via USPS or UPS.
She was arrested on March 14 after law enforcement executed a search warrant at her home and recovered “large amounts” of heroin, fentanyl and cocaine in her garage.

Authorities also seized computers, cellphones, packages being prepared for shipment, packaging materials, a heat sealer, a digital scale and her “signature overdose warning cards” — a note detailing the dangers of the narcotic and suggesting users have Narcan on hand when using them.
Narcan, the brand name for naloxone, is a nasal spray used to reverse life-threatening opioid overdoses.
On Thursday, Tolin pleaded guilty to one count each of criminal possession of a controlled substance and attempted operating as a major trafficker. She admitted to selling more than $75,000 worth of narcotics from September 2024 to March 2025, Suffolk County District Attorney Raymond A. Tierney said, calling the scale of her operation “astounding.”
Tolin has been in custody since her March arrest and was remanded without bail following the plea, officials said.
She is scheduled to be sentenced on Jan. 8, according to online court records. She faces 15 years in prison followed by five years of post-release supervision.
