U.S. Charges Alleged Los Rugrats Leader Carlitos Rugrats With Narcoterrorism

The United States has unsealed a major indictment against Carlos Paez Pereda, better known as “Carlitos” or “Carlitos Rugrats,” charging him with narcoterrorism, material support of terrorism, drug trafficking, and money laundering tied to the Sinaloa Cartel. Federal prosecutors in San Diego identify him as a high-ranking lieutenant and the alleged leader of Los Rugrats, an armed group working for the Mayo Zambada faction.  

The case is about more than one trafficker.

It lands directly in the middle of the Sinaloa split: Los Mayos versus Los Chapitos. And inside that fight, Paez Pereda is not being framed as some outside contractor. U.S. prosecutors allege he helped the Mayo side with fighters, weapons, logistics, and money during the war with the sons of Joaquín “El Chapo” Guzmán.  

That puts the indictment inside the orbit of Ismael Zambada Sicairos, “El Mayito Flaco,” the figure now most associated with La Mayiza after the fracture of the old Sinaloa structure. Mexican reporting has described Carlitos Rugrats as an operator for Mayito Flaco and one of the armed figures who gained weight as the Mayo faction reorganized during the conflict with Los Chapitos.  

According to the Justice Department, Paez Pereda operated a manufacturing and distribution network for methamphetamine, fentanyl, and cocaine. Prosecutors say he also enforced cartel operations in Sinaloa and Tijuana through murder, kidnappings, and armed men. They allege he controlled part of the transportation pipeline moving drugs from Sinaloa to Tijuana and then into the United States.  

That is the real weight of the case.

Los Rugrats are not being treated as just another crew with guns and a nickname. The U.S. is tying them to the fentanyl pipeline, the Mayo faction’s war machine, and the violence used to keep cartel routes open.

The indictment charges Paez Pereda with narcoterrorism, material support of terrorism, continuing criminal enterprise, international drug conspiracy, importation conspiracy, distribution conspiracy, and money laundering conspiracy. The narcoterrorism charge carries a possible life sentence and a mandatory minimum of 20 years. The continuing criminal enterprise charge also carries a possible life sentence.  

This is where the legal shift matters.

For years, the U.S. mostly went after cartel figures as traffickers. Now prosecutors are using the terrorist designation against cartel operators accused of moving fentanyl, commanding armed groups, laundering money, and supporting factional violence. The Sinaloa Cartel’s designation as a Foreign Terrorist Organization gives federal prosecutors a different weapon, and this case shows how they are starting to use it.  

The FBI has also placed Carlos Alberto Paez Pereda on its wanted list. The bureau says he is wanted for allegedly trafficking large amounts of fentanyl, cocaine, and methamphetamine from Mexico into the United States, while leading Los Rugrats for the Mayo Zambada faction.  

Treasury had already moved against him before this indictment. In September 2025, OFAC identified Paez Pereda as the leader of Los Rugrats, based in Laguna Colorada, Sinaloa, and described him as a fentanyl producer and one of the major narcotics traffickers in Culiacán. Treasury also tied him to violence against rival cartel figures.  

So the sequence is clear.

First came the sanctions.
Then the FBI wanted notice.
Now the narcoterrorism indictment.

That is pressure, step by step.

For Mexico, the case points back to the war that has been bleeding Sinaloa since the split between Los Mayos and Los Chapitos. For the United States, it points to fentanyl, cartel money, and the armed structures behind the drug flow.
