MIAMI – A California duo accused of operating a darknet drug trafficking business that sold fentanyl and methamphetamine nationwide, including in South Florida, and laundered hundreds of thousands of dollars in cryptocurrency has been indicted by a Southern District of Florida grand jury. 

According to court documents, Nicholas Aguilar, 44, and Jessica Marcolina, 37, both of Los Angeles, allegedly operated vendor accounts under the moniker “HotGirlzClub” on multiple darknet marketplaces, where they conspired to distribute controlled substances — including fentanyl and methamphetamine — to customers throughout the U.S., including in Miami-Dade and Broward counties. Aguilar and Marcolina also allegedly conspired to launder cryptocurrency proceeds from the drug sales through transactions designed to conceal the source and ownership of the funds.

It is alleged that from as early as 2020, continuing through the date of their arrest, the defendants were consistently shipping parcels containing controlled substances using the U.S. Mail.  According to the complaint, in a seven-month period alone in 2025, law enforcement allegedly identified more than 500 shipped parcels believed to contain narcotics that were linked to the operation.

Searches of the defendants’ residences in California revealed distribution quantities of suspected controlled substances, drug packaging materials, printed warning labels, U.S. Postal Service (USPS) shipping supplies, a label maker, heat and vacuum sealer, a food processor containing suspected narcotics residue, electronic devices, fraudulent identification documents bearing the names of identity theft victims, and firearms. Law enforcement also recovered warning inserts identical to those included in undercover purchases. The inserts cautioned customers about the risk of overdose, advising them to “be safe until you know your tolerance for the product,” demonstrating the defendants’ awareness of the dangers posed by the narcotics they allegedly distributed.

The search also revealed that Aguilar possessed two loaded handguns and a rifle and operated an illicit firearms manufacturing operation that produced ghost guns, suppressors, and firearm upper and lower receivers.

Aguilar and Marcolina are charged with conspiracy to distribute controlled substances and conspiracy to commit money laundering. If convicted, they each face up to life imprisonment on the drug trafficking conspiracy count and up to 20 years’ imprisonment on the money laundering conspiracy count.
