Riverhead, NY – Suffolk County District Attorney Raymond A. Tierney announced Thursday that Carolyn Tolin, 46, of Centereach, has been sentenced to 15 years in prison for operating a large-scale narcotics business known online as MamaKnowsBrown, which trafficked fentanyl, heroin, and cocaine to customers nationwide through the dark web.

According to prosecutors, from September 2024 to March 2025, Tolin ran an organized drug distribution network from her Centereach home. Through her dark web vendor account, she sold more than $75,000 worth of illegal narcotics, offering customers multiple shipping options and even allowing product reviews. Payments were accepted in cryptocurrency, which she later converted into cash.

On March 14, 2025, law enforcement executed a search warrant at her residence, where they recovered significant quantities of fentanyl, heroin, and cocaine, along with packaging materials, a digital scale, computers, and phones used in the operation.

Tolin pleaded guilty on November 20, 2025, to one count of criminal possession of a controlled substance in the first degree, a Class A-1 felony, and one count of attempted operating as a major trafficker, a Class B felony, before Acting Supreme Court Justice Richard I. Horowitz. She was sentenced on January 22 to 15 years in prison, followed by five years of post-release supervision.

The case was prosecuted by Assistant District Attorneys Kristin Barnes and Matthew Laube of the Violent Criminal Enterprises Bureau, with investigative work by Richard Pedigo of the Suffolk County Sheriff’s Office and the District Attorney’s Fentanyl Task Force.
