Fentanyl Delivered to Your Door in the U.S.: the Network That Ships Drugs by Mail Without Going Through Mexico

“Sol Prendido” for Borderland Beat 

In Toledo, Ohio, Marcus Gaines donned his U.S. Postal Service (USPS) uniform every morning and headed out to deliver the mail. What his neighbors didn't know was that, along that very same route, he was also delivering fentanyl, heroin, and cocaine right to people's doorsteps. He charged $500 per package.

While Donald Trump has designated fentanyl a "weapon of mass destruction" and pressures Mexico with threats of military intervention, a database compiled by MILENIO—based on 36 court records made public by the Department of Justice (DOJ)—reveals that the problem has senders and recipients located right within the United States.

That’s right: the country’s postal service has become a conduit for corrupt mail carriers, gang members, networks directed from prison cells, and packages sent under fictitious names—all without U.S. authorities themselves having been able to put a stop to the problem.

The records reviewed by this publication reveal that at least 80 individuals have been prosecuted over the last 15 months for using the postal service to traffic hard drugs. The majority of these cases—six out of every ten—operated exclusively within U.S. territory, with no ties to Mexican cartels.

Deliveries span from Tennessee to Hawaii, and from Ohio to Florida. Sometimes the drugs travel concealed within books—their pages soaked in synthetic narcotics—or in packages addressed to hotel front desks, such as those at Holiday Inn Express; other times, they arrive in correspondence disguised as legal letters, or in shipments delivered by a mail carrier along his own route in exchange for $500 per package.

In July 2025, the White House itself acknowledged the magnitude of the problem: in fiscal year 2024, 98 percent of all narcotics seizures involving customs cargo originated from shipments valued at less than $800—shipments that were exempt from standard customs inspections. That universe reached 1.36 billion packages annually, circulating through both private carriers—such as FedEx and UPS—and the international postal service, where inspections were equally minimal or nonexistent.

Phantom Senders and Recipients: The Network the Government Cannot Shut Down

In its semiannual report of April 2025, the Postal Service Inspector General acknowledged that drug trafficking organizations are actively targeting postal employees because these workers have access to the Postal Service’s vast distribution network.

Gaines, the mail carrier from Toledo, is just one example—but not the only one. In October of that same year, the same agency documented the case of a female mail carrier who smuggled in 62 kilograms of cocaine, fentanyl, and heroin concealed within ordinary shipments.

The preferred method for those utilizing the mail is simple: packages bearing false names. Jose Ruben Leyva shipped fentanyl from Phoenix, Arizona, to Columbus, Ohio, using invented senders and recipients; his associate, Ontario Yarbrough, received at least five packages and tracked another 13 in the Columbus area from a house in the Hilltop neighborhood, where authorities discovered 500 grams of fentanyl, bags of white powder, weapons, ammunition, and cash.

There are many more such cases. Take, for instance, that of Justin Dupras from Massachusetts, who would fly to California, purchase cocaine, mail it that very same day, and catch a return flight home. He was arrested when he arrived to pick up the package at the Fall River post office.

Organizations are targeting postal workers because of the extensive access they have.

Torrez Drane, a 32-year-old man, engaged in a similar scheme: he made several trips to California, purchased large quantities of methamphetamine, and mailed them to Louisiana, where he personally redistributed them throughout the southern part of the state.

Of the cases revealed through U.S. Department of Justice reports, 31 were prosecuted in 2025, and five in the first months of 2026. Fifty-eight percent—specifically, 21 cases—operated entirely within U.S. territory, with no direct ties to foreign cartels.

Fentanyl or carfentanil figured in 17 of the 36 cases; methamphetamine, in 15; and cocaine, in 11. Massachusetts accounts for nine of the case files; Ohio, six; and Florida, five. The remaining cases are scattered across the country, ranging from Alaska to South Carolina, and from Idaho to Hawaii.

Court records reveal cases where drug shipments sent via the postal system originated from within prisons. Such is the case of Anthony Bravo, who coordinated a network trafficking methamphetamine and carfentanil—the latter being 100 times more potent than fentanyl—between California and Hawaii, using contraband cellphones from a state penitentiary. The shipments were sent via federal mail (USPS) and arrived in Kauai, an island in the Hawaiian archipelago.

In Florida, Mario Clifford Rivera—known as "Chuky"—a member of MS-13 (a gang designated as a terrorist organization by Trump in February 2025), also operated his fentanyl network from inside a state prison, utilizing a contraband cellphone and the U.S. Postal Service.

In Massachusetts, the H-Block gang devised a different solution to supply inmates: they soaked sheets of paper in synthetic cannabinoids, printed them with fake law firm letterheads, and mailed them as legal correspondence. Guards typically did not inspect letters from attorneys.

The same scenario unfolded in Ohio: Austin Siebert used a homemade binding machine to infuse the paper of paperback books with synthetic drugs, which he then mailed to the Grafton Correctional Institution.

Other International Shipments

While Trump has focused his attention on Mexico, Department of Justice records document other routes involved in postal trafficking. In Florida, a man named Dudzinski Poole led a 17-person organization that received fentanyl directly from China via mail; over a two-year period, nearly 400 packages were shipped from California to Florida. Poole laundered the proceeds by paying legitimate artists to organize concerts.

In Framingham, Massachusetts, four undocumented Brazilian nationals operated a clandestine pharmacy catering to the Portuguese-speaking community, importing controlled medications from Brazil via the mail.

There are also documented cases of drug trafficking via mail bearing Mexican postage stamps. Fidel Félix Ochoa, a leader of the Sinaloa Cartel  extradited by Mexico to the United States on January 20, 2025, directed mail-based distribution operations from Mexico. According to the Department of Justice, his case serves to illustrate the significant role played by the postal service within drug trafficking routes.

Federal prosecutors in Florida identify him as one of the key leaders of the Sinaloa Cartel responsible for directing trafficking and money laundering activities; they allege that he coordinated the entry of hundreds of kilograms of fentanyl and cocaine into the United States, utilizing both human couriers and the U.S. postal service itself.

There are records of other international routes in postal traffic, such as China and Brazil. 

Another individual sentenced in Texas to more than 26 years for supplying fentanyl from Mexico was Juan Manuel Navarette Robles. The Department of Justice reported that this Mexican trafficker was sentenced in East Texas to 315 months in prison—that is, just over 26 years—after pleading guilty to conspiracy to distribute fentanyl.

According to information presented in court, Navarette Robles was a high-level source for the supply of fentanyl and methamphetamine from Mexico; he trained others and directed drug distribution within U.S. territory, primarily utilizing the postal service and various hubs or receiving points.

The illicit cargo was then redistributed to Texas and other destinations. Navarrete traveled to the United States, where he was apprehended in possession of substantial quantities of fentanyl.

In Nebraska, a woman named Amy Holmdohl was awaiting her packages of methamphetamine—sent from Mexico—at the front desk of a Holiday Inn Express in Omaha.

According to data from Customs and Border Protection (CBP) released in August 2025, fentanyl seized in international mail had an average purity exceeding 90 percent—a stark contrast to the less than 10 percent purity found in fentanyl intercepted at the land border.

At least 80 people have been prosecuted for this crime over the past 15 months.

The volume of these shipments rose from 134 million in 2015 to 1.36 billion in 2024—four million packages daily, the majority of which went unchecked.

These cases involve at least 80 implicated individuals who exploited the postal infrastructure, whether through local networks, transnational operators, corrupt employees, logistics intermediaries, or schemes for the receipt and distribution of packages within the United States.
