“Sol Prendido” for Borderland Beat 




In a press release, the Attorney General's Office (FGR) announced that Sergio “N” has been formally charged and bound over for trial for his alleged involvement in a crime against public health, specifically in the modality of narcotics transport.


The Federal Public Prosecutor’s Office (MPF)—operating under the Specialized Regional Control Prosecutor’s Office (FECOR) in Zacatecas—presented the formal charges against the defendant. Consequently, the presiding judge ordered the precautionary measure of justified preventive detention and allotted a two-month period for the complementary investigation.


The inquiry was initiated following the transfer of custody of the suspect by the Mexican Government’s Security Cabinet—specifically by personnel from the Secretariat of National Defense (SEDENA). This action followed the suspect's apprehension on Federal Highway 54 (Zacatecas–Saltillo section), near the community of Sierra Vieja in Villa de Cos, Zacatecas, while he was traveling aboard a cargo vehicle.


At the time of the arrest, authorities seized 651 kilograms, 154 grams, and 8 milligrams of marijuana; 1 kilogram, 12 grams, and 30 milligrams of methamphetamine; a cellular phone; and the vehicle itself.


The press release emphasized that the individual mentioned in this statement is presumed innocent until such time as a final conviction is issued by a competent judicial authority.

CJNG Narco Tunnel Discovered in San Diego Storefront, Over 1 Ton of Cocaine Seized

 "Socalj" for Borderland Beat


A nearly 2,000-foot-long tunnel stretching from Tijuana to Otay Mesa was recently discovered by law enforcement officials, leading to federal drug distribution charges announced Monday against four people.

According to the U.S. Attorney's Office, the tunnel led into a fake discount store in Otay Mesa called Buy 4 Less, which investigators have been surveilling since December due to suspicious activity.

Investigators regularly saw a group of supposed employees in and around the store, though the location "did not appear to be consistent with a normal retail location" and featured "minimal foot traffic from customers coming in and out of the Buy 4 Less store," according to the U.S. Attorney's Office.

Authorities also surveilled numerous empty suitcases leaving the store and being walked across the nearby border crossing into Mexico on several occasions.

Samuel Meléndez Carrisoza, aka El Sierra, Sentenced to 10 Years in Prison

“Sol Prendido” for Borderland Beat 





The man was arrested in 2025 during an operation in Durango where authorities seized fentanyl, cocaine, and weaponry.


The Attorney General's Office (FGR) announced that it has secured a sentence of 10 years and 10 months in prison against Samuel “N”—alias “El Sierra”—whom authorities have identified as a financial operative and second-in-command of a criminal group affiliated with the Los Chapitos faction of the Sinaloa Cartel.


According to the agency, the conviction was the result of investigations and evidence presented by the Specialized Prosecutor's Office for Organized Crime, which established his culpability in crimes related to the possession of firearms, magazines, and ammunition designated for the exclusive use of the Armed Forces, as well as the possession of narcotics with intent to distribute.


The FGR noted that Meléndez Carrisoza is required to serve his sentence at Federal Center for Social Readaptation No. 7, located in Durango.


“El Sierra” was arrested in January 2025 during an operation conducted by federal forces in the city of Durango. Authorities executed a search warrant at a property where they seized firearms, magazines, ammunition, fentanyl pills, cocaine, and other items linked to illicit activities.


According to information from the Attorney General’s Office itself, Samuel “N” was considered a financial operator and the second-in-command of “Los Deltas,” an armed cell linked to “Los Cazadores”—a group affiliated with the Sinaloa Cartel’s faction known as “Los Chapitos.”


The sentencing comes amidst federal authorities' efforts to dismantle the operational and financial structures of criminal organizations maintaining a presence across various regions of the country—particularly those involved in the trafficking of synthetic drugs.


With this ruling, the FGR highlighted the conclusion of one of the investigations stemming from operations carried out by the Security Cabinet in Durango during 2025, which aimed to apprehend alleged members of criminal groups operating in northern Mexico.

FGR Pursues Maru for Refusal to Testify in "CIA Case" and for Kidnapping Charges Filed by Corral

“Sol Prendido” for Borderland Beat 





 The "4T" administration is going all out to remove Governor Maru Campos from office.


The FGR (Attorney General's Office) warned this evening that Maru isn’t above the law.


The Governor of Chihuahua—acting in defiance—refused to testify before the FGR this Wednesday; instead, she sent a letter explaining that she is under no obligation to appear.


The FGR countered that her immunity from prosecution doesn’t exempt her from providing information regarding the case involving CIA agents who were operating in Chihuahua.


Maru is also scheduled to appear in Mexico City this Friday to be formally notified of the kidnapping lawsuit filed against her by Javier Corral; however, the Governor does not intend to appear for that proceeding either.


Morena is already moving forward with proceedings in the Chamber of Deputies to strip Maru of her immunity on charges of treason against the nation, and it appears that her days as Governor are numbered.


* The era known as the Fourth Transformation, or "4T," in Mexico is more than just a political term; it represents the transformative vision of former President Andrés Manuel López Obrador (AMLO). This vision is anchored in a series of profound and radical changes that place his administration on par with significant historical events in Mexico, such as the Independence, the Reform, and the Revolution.

Targeting The Money: OFAC Escalates Pressure Against The Chapitos

On May 20, 2026, the Office of Foreign Assets Control (OFAC) issued sanctions against individuals and entities tied to two separate money laundering networks linked to the Sinaloa Cartel and its Chapitos faction for drug trafficking and money laundering activities.

The sanctions targeted two criminal networks responsible for the illegal trafficking of fentanyl from Mexico into the United States and for laundering the proceeds through cryptocurrency exchange schemes.

The action resulted from a coordinated investigation led by the Homeland Security Task Force (HSTF), involving the Drug Enforcement Administration (DEA) and OFAC, pursuant to Executive Order (E.O.) 14059, which targets the proliferation of illicit drugs and their means of production, and E.O. 13224, which targets terrorists and their supporters. The sanctions were also coordinated with the Mexican government’s financial intelligence unit, the Unidad de Inteligencia Financiera (UIF).

 


Targeting Wholesalers and Money Laundering Networks

The first set of sanctions focused on one of the Chapitos’ principal revenue-generating operations: the laundering of proceeds derived from illicit fentanyl sales. The network was allegedly led by Armando de Jesus Ojeda Aviles, who oversaw the collection of bulk cash in the United States and the integration of those funds into the cryptocurrency ecosystem before transferring the money to Mexico through blockchain transactions.

Armando de Jesus Ojeda Aviles reportedly took control of the criminal network after the death of Mario Alberto Jimenez Castro. The organization was responsible for overseeing narcotics shipments and laundering drug proceeds generated in the United States. Ojeda Aviles’s network consisted of Mexico-based drug suppliers and U.S.-based couriers tasked with collecting bulk cash derived from drug trafficking activities.

Also involved in Ojeda Aviles’s network were Jesus Alonso Aispuro Felix and Rodrigo Alarcon Palomares, who coordinated cryptocurrency transfers tied to the laundering of drug proceeds. In October 2023, Alarcon Palomares was detained in Mexico after authorities found him in possession of weapons and ammunition.

Another figure linked to the network is Alfredo Orozco Romero, who allegedly operated as a security advisor and debt collector for unpaid drug shipments. Authorities also identified him as controlling the Mexican company Grupo Especial Mamba Negra, S. de R.L. de C.V., as well as the Chihuahua-based restaurant Gorditas Chiwas, through family members Amalia Margarita Romero Moreno and Liliana Orozco Romero.

The second sanctioned criminal network was allegedly led by Jesus Gonzalez Penuelas, who authorities claim has been involved in large-scale drug trafficking operations since 2007, including the production and distribution of methamphetamine, heroin, cocaine, and fentanyl. In 2018, Gonzalez Penuelas was indicted in the United States on international drug trafficking charges. In January 2024, the DEA announced a $5 million reward for information leading to his arrest and/or conviction.

Also sanctioned alongside Gonzalez Penuelas were Castulo Bojorquez Chaparro, Fredi Ismael Garcia Sandoval, Luis Arnulfo Moreno Zamora, Baltazar Saenz Aguilar, and Noe de Jesus Castro Rocha. According to U.S. authorities, the group coordinated drug distribution, bulk cash movement, and money laundering operations tied to drug trafficking activities.

 

 “Drowning” The Chapitos

These sanctions are significant because, unlike operations targeting sicarios or plaza bosses — who are often quickly replaceable — authorities are now focusing on the financial structure that allows the Chapitos to operate.

The operation not only targets profits generated from individual drug shipments. It also disrupts the financial operators and distribution networks responsible for moving and integrating illicit proceeds into the formal economy. Coordinating these actions alongside Mexico’s UIF could produce a more immediate financial impact by disrupting key revenue streams essential to the organization’s operations.

Replacing experienced wholesalers, money launderers, and transnational financial operators is considerably more difficult than replacing a local plaza boss or even a synthetic drug precursor brokers. For that reason, these sanctions could represent a more strategic long-term threat to the Chapitos’ operational capabilities.

The sanctions also come amid ongoing rumors that Ivan Archivaldo Guzman Salazar and Jesus Alfredo Guzman Salazar may have been involved in discussions with U.S. authorities regarding a possible surrender agreement. Regardless of whether the surrender rumors are true, the sanctions demonstrate that U.S. and Mexican authorities are increasingly prioritizing the financial and logistical infrastructure sustaining the Chapitos’ drug trafficking operations.

7 Mayors Arrested in Mexico: Harfuch Warns They Will Pursue Politicians “Regardless of Party”

“Sol Prendido” for Borderland Beat 





Seven mayors have been detained in Mexico—regardless of their political party affiliation—highlighted Omar García Harfuch, head of the SSPC, while affirming that there will be no impunity for those with ties to organized crime.


On Wednesday morning, the Secretary of Security and Citizen Protection, Omar García Harfuch, warned that there would be no impunity for political figures linked to criminal activity.


During the morning press conference held by President Claudia Sheinbaum, the official revealed that, so far during this administration, 85 public servants have been successfully detained. Prominent among those arrested are seven municipal mayors from various jurisdictions.


In a previous interview granted to *La Jornada*, the Secretary emphasized the non-partisan nature of these actions:


“Wherever there are indications and evidence against those who commit crimes—whether they are current or former public officials—they will be investigated and detained. It is also very important for the citizenry to know that this applies regardless of party or political stripe; in these cases, those involved come from every party—from across the entire political spectrum.”


**High-Impact Statistics**


Harfuch asserted that the security strategy has resulted in a 49% reduction in intentional homicides between September 2024 and May 2026. This decline—described by the Secretary as “unprecedented”—is accompanied by the capture of 54,300 individuals for high-impact crimes.


The official report details a significant financial and operational blow dealt to criminal organizations through the seizure of:


*   More than 400 tons of narcotics.

*   2,400 destroyed clandestine laboratories.

*   Nearly 30,000 seized firearms (78% of U.S. origin).


García Harfuch reiterated that the primary objective is to ensure that “there are fewer criminals on the streets and that peace increases among the population,” while maintaining vigilance over the conduct of public officials at all levels.
