A family business in the darknet: a couple from Los Angeles laundered cryptocurrency from fentanyl sales
A federal grand jury in the Southern District of Florida has formally indicted two Los Angeles residents—44-year-old Nicholas Aguilar and 37-year-old Jessica Marcolina. According to the investigation, the couple operated a large-scale drug distribution network across the United States through the darknet, and then laundered hundreds of thousands of dollars in cryptocurrency obtained from the sale of fentanyl and methamphetamine.
Details of the Criminal Scheme
It has been established that the defendants managed seller accounts under the pseudonym HotGirlzClub on several darknet platforms. The distribution of prohibited substances via postal shipments has been ongoing since at least 2020. In just seven months of 2025, law enforcement recorded over 500 suspicious packages linked to this group.
During searches of the suspects' homes in California, large quantities of drugs, packaging materials, and forged documents in the names of identity theft victims were discovered. Additionally, inserts warning of overdose risks were seized—the prosecution considers this direct evidence that the defendants were aware of the danger of their activities.
Particular attention was drawn to a workshop equipped by Aguilar, where so-called "ghost" guns, silencers, and receivers were manufactured. During the search, two loaded pistols and a rifle were also found in his possession.
Cryptocurrency Chains and the Role of Monero
To launder their proceeds, the criminals used complex multi-step cryptocurrency transactions. Funds were transferred through a long chain of wallets to obscure the trail and conceal the ultimate owners. The U.S. Department of Justice press release explicitly states: "Aguilar and Marcolina conspired to launder cryptocurrency obtained from drug sales through transactions designed to conceal the original sources and owners of the funds."
Darknet markets remain a key link in the illegal crypto economy. According to data from the analytical platform Chainalysis, nearly $2.6 billion in on-chain flows passed through them in 2025. Bitcoin (BTC) continues to dominate, but its open blockchain allows transactions to be traced. As a result, more sellers are switching to Monero (XMR)—a privacy coin that is virtually impossible to track.
Aguilar and Marcolina have been charged with conspiracy to distribute prohibited substances and money laundering. The first charge carries a potential life sentence, while the second carries up to 20 years in prison.
Expert Commentary: This case is a vivid illustration that cryptocurrency anonymity is a double-edged sword. On one hand, Monero and mixers do complicate investigations, but on the other hand, law enforcement is increasingly using blockchain analysis to uncover illegal schemes. The market anticipates tighter regulation of privacy coins, and likely within the next couple of years, we will see new restrictions at the level of exchanges and service providers.
