A Long Island woman who sold drugs on the dark web under the alias “MamaKnowsBrown” has pleaded guilty to running a nationwide fentanyl ring from her garage.
As detailed in the Suffolk County District Attorney’s press release, 46-year-old woman Carolyn Tolin has pleaded guilty to criminal possession of a controlled substance in the first degree, and attempted operating as a major trafficker. She allegedly utilized Uber, UPS, and the United States Postal Service to send drugs, including fentanyl, to customers across the country in exchange for cryptocurrency.
Between September 2024 to March 2025, Tolin sold and possessed over $75,000 worth of cocaine, crack cocaine, fentanyl, and heroin. She shipped the product both locally and nationally, with Uber utilized within Suffolk County and UPS or the Postal Service for customers outside the county.
“The scale of the operation that this defendant ran out of her Centereach garage is astounding,” said District Attorney Tierney. “I want to thank the investigators and prosecutors on this case for uncovering this sophisticated operation and bringing this defendant to justice. Let it be known, anyone distributing or possessing these dangerous poisons will be fully investigated and prosecuted.”
Inside the packages of drugs she sent out, she would include a card that warns users that her product carries a high potential to cause an overdose. The note cautioned them to have Narcan, the spray that can save the lives of anyone suffering from an opioid overdose.
When authorities searched her property in Centereach on March 14, 2025, they seized computer equipment, cellphones, packaging materials, a digital scale, her warning cards, and large amounts of various drugs. She is facing a 15-year prison sentence, followed by five years of probation.
