"Socalj" for Borderland Beat

Zetas Founding Member 'Don Zefe' Killed; He Also Resided in US & Canada

"Morogris" for Borderland Beat

Zeferino Pena Cuellar, alias Don Zefe or El Zefe, key figure in the creation of Los Zetas, was killed this week in Nuevo Leon

Nuevo León state authorities confirmed that Zeferino Peña Cuéllar, commonly known by his alias "Don Zefe," was killed in a shootout with police officers at his estate in Santiago, Nuevo León. Don Zefe was affiliated with the Gulf Cartel during the 1990s and early 2000s and is often cited as one of the founding members of the core group that later evolved into Los Zetas under the leadership of kingpin Osiel Cárdenas Guillén. However, Don Zefe largely avoided law enforcement scrutiny and media coverage over the years up until his death and was believed to have retired for several years.

The incident occurred early in the afternoon on Tuesday, December 23, when the State Investigative Agency (AEI) reported the presence of armed men near an estate in Santiago. Upon arriving at the scene, authorities came under gunfire, resulting in a shootout.

Two men were killed during the exchange, and local media quickly reported that one of them was Don Zefe. The other victim was David Calderón, a former military officer. Investigators later confirmed that Don Zefe was suspected of managing drug trafficking operations in Nuevo Leon, reportedly under a new criminal organization he was attempting to establish in the area.

Sources consulted by Borderland Beat indicated that Don Zefe had been spending a considerable amount of time in Nuevo León since the pandemic. His activities remained largely unknown for years because he had retired for an extended period. Upon emerging from retirement, he maintained a low profile while attempting to form a new criminal organization, possibly operating as an independent drug trafficker.

CDG Chismes: El Flaco Arrest & More

 By Itzli. 


Our fourth installment of CDG chismes, where I break down the latest online news, rumors, and gossip about the Cártel del Golfo (CDG, Gulf Cartel) and try to put it in context. This time we’ll be covering stuff from March 27th until today.


Arrest of El Flako

Well I decided to change things up and get to the good stuff first rather than do things fairly chronologically seeing how writing at the end last time that “El Chive” and “El Toñín” are out of jail didn’t get much reaction. Jorge Luis “El Flaco” Chávez Hernández got arrested yesterday, news that’s important enough that major Mexican media like Milenio covered it. Some report it took place in Reynosa, others, in San Fernando. Putting it all together I believe there were searches in and around San Fernando, they found him in a safehouse, immediately took him to Reynosa to be presented and some reporters just assumed the arrest took place in Reynosa.


Alright, so unless you follow this stuff closely you’re probably wondering who “El Flaco” is, especially since some are saying he’s a regional leader of Los Zetas. If you look at all the mainstream articles, besides variation on where he was arrested they all report the same couple of facts:


  • Responsible for killing to soldiers and a Guardia Estatal officer in August 2024

  • Had a 850 thousand peso reward for information leading to his arrest


From there there’s a few more pieces of information that are in the mix, with articles picking them up piecemeal:  


  • Also known as “El Gory”

  • Leader/member of Zetas Vieja Escuela 

  • Responsible for violence in San Fernando, Méndez, Burgos, Cruillas, Santander Jiménez, Abasolo, Soto la Marina, and Aldama.

  • The August 2024 attacks happened after his wife Diana Laura “J” was arrested


Shout out to Hoy Tamaulipas for actually reshaping information by writing: “His criminal influence encompassed key municipalities such as Jiménez, Abasolo, Soto la Marina, and Aldama, later extending to Burgos, Méndez, and Cruillas after aligning with criminal cells in San Fernando and Reynosa”.


For those of you that don’t already know, I’m not a “real” journalist, as you can see they all regurgitate the government press release and call it a day. As a self proclaimed researcher I crave information and context and that’s what I openly share, so here goes.


Circumstantial evidence points to Jorge Luis Chávez Hernández being a native of the Jiménez municipality as that full name appeared on a Tamaulipas state government website in May 2013. Regardless, back in that timeframe the Aldama/Soto la Marina/Abasolo corridor was under the control of José “El Gordo Cachetes Sánchez García, who was connected to Mario “El Pelón” Armando Ramírez Treviño going back to 2010. It looks like “El Flaco” worked under him, on July 10, 2014 there were a couple of operations targeting “El Gordo Cachetes” and in the one taking place in Allende, between Abasolo and Jiménez, Jorge Luis Chávez Hernández was arrested. Reporting from that time described him as “leader of a criminal group in the Abasolo municipality”. 


About a week later Los Panteras, a group that worked under “Mario Pelón” was forced out of Río Bravo and found protection under “El Gordo Cachetes”. Thus was born the so called Centro Faction of the CDG and Víctor Manuel “El Viento” Pérez Rico, code name “Pantera 16”, took over the region after “El Gordo Cachetes” was arrested in April 2015. “Pantera 16” was leader up until his arrest in August 2018 and then under Pablo Misael “El Mezqui” Ramos Lara, code name “Pantera 24”. In August 2022 the Matamoros Faction turned against “Pantera 24” over alleged dealings with the CJNG and he joined up with the San Fernando Faction, made up of Zetas Vieja Escuela (ZVE) remnants and Los Sierras


War broke out between the San Fernando Faction and the Matamoros Faction in April 2023, two months later “Pantera 24” was arrested. It seems that “El Flaco” took his place at that point as leader of the remnant Los Panteras/Centro Faction forces that worked alongside the San Fernando Faction and we see him brought up alongside “Chuy 7” and “El Nico” by October 2023. Since then he seems to have focused on trying to recover the old Centro Faction territory that the Matamoros Faction took from them. 


As for the whole August 2024 attacks, what happened is authorities had been after “El Flaco” and it wound up that authorities caught his wife Diana Laura Jasso Orozco along with Olga Alicia Vela Medina and a child. Since she was involved in kidnappings and charging extortion, she was arrested, he got pissed and thus the attack happened.


To feed the skeptical side that feels major arrests don’t just happen out of the blue, there’s video of ZVE forces fleeing to Nuevo Leon due to San Fernando “heating up” on Tuesday, April 2nd. Besides that it looks like there was a clash between cartel forces between Soto la Marina and Aldama on Saturday, April 5th and a cartel attack against Guardia Estatal in Padilla on Sunday, April 6th.


Arrest of La Chiva

In other news, Martín “La Chiva” Elizondo Rodríguez was arrested on Friday, March 28th. Officials say that he was leader of the Matamoros Faction/Los Escorpiones in Ciudad Victoria. So this should be big news but it is being said that he’s actually a low level guy of minor importance. Menny Valdez is one of the strongest ones making these claims, pointing out that he is only being charged with weapons violations and that the true head of plaza is allegedly “K-16”


Arrest of “El Pony”

Then there’s the arrest of Fabian “Comandante Pony” Silva Aguirre in Brownsville by the United States Border Patrol. Big news? I can’t find any information about him outside the press release so it doesn't seem like he’s important but hey, an arrest is an arrest I guess.


CDN/Los Metros

The war between the Cártel del Noreste (CDN) and Los Metros continues so here’s a quick breakdown of what’s been happening:



El Truco Update

In the CDG Matamoros series I wrote about some of the rumors surrounding politician César Augusto “El Truco” Verástegui Ostos. Despite losing his campaign for governor of Tamaulipas he’s still around and involved in things. A report on March 27th claims that he had a secret meeting with the former mayor of San Fernando, Maybella Lizeth Ramirez Saldivar, as well as meetings with “Chuy 7”. It was pointed out that it would be strange for the meeting to be secret as they are both from the same political party. 


Furthermore, another member of their party, Diana Vanessa Leal López, the current mayor of Cruillas, allegedly had her home searched by members of the army on March 26th. In this version of events, “El Truco” is actually meeting with CDN members who seek to take control of central Tamaulipas and La Columna Armada/Hidalgo Faction of the CDG will potentially be attacked.


El Mante

As discussed in CDG Matamoros Part 15, Luís “La Güicha” Yañez Álvarez (his alias alternately spelled “La Guicha” and “La Wicha”) has been in charge of Ciudad Mante for this cartel. On March 27th it was reported that vehicles with armed men being spotted the day before in the city was a signal that things were heating up and separately reminded that “La Wicha” and others were formerly members of Los Zetas. 


Information is still coming out today about a federal operation targeting “La Wicha” and his second in command, Bryan “El Mulas” Castillo. Another line of rumors indicates that Cinthia Deyanira “La Negra” Garza Velázquez was arrested yesterday in Ciudad Mante. This isn’t the first time these individuals have been targeted, so maybe it’s more of the same but it’s worth noting that the former leader of Los Zetas in the area, Enrique “El Varo” Puga Cortez, has been out of jail for a year and is allegedly associated with “El Truco”...

Throwback Thursday: The Wedding That Exposed "Los Zetas".

 "Char" for Borderland Beat 

This article was translated and reposted from LA SILLA ROTA 


An album of photographs found in a house belonging to "Comandante Ardilla" revealed the close circle of "Los Zetas".




Small in stature, with a cheeky smile, a challenging look, unkempt and unshaven, this is how Salvador Alfonso Martinez Escobedo, "El Comandante Ardilla," the head of "Los Zetas" in the northeast of the country, was presented to the media by the Secretary of the Navy (Semar). It was October 8, 2012. 

The capture was important, "El Comandante Ardilla" was one of the most bloodthirsty men in the cartel.

Alleged Zetas Founder 'El Chocotorro' Reveals His Identity On Social Media, Then Removes Videos (Updated)

"Morogris" for Borderland Beat

Update: On the evening of 11 January 2024, days after this story was posted, his videos were reinstated on his YouTube channel for a few hours. They are not available again.

Several days ago, an individual purporting to be Daniel Enrique Márquez (El Chocotorro), an alleged founding member of Los Zetas, uploaded multiple long-form videos on YouTube detailing his military and organized crime background.

These long-form videos have since vanished from social media platforms after garnering attention. A handful of shorter clips remain, but the original recordings are no longer accessible.

Who is El Chocotorro? Can the man in the video be trusted with what he says? And was this individual truly the mentioned founding member of Los Zetas?

Unnamed Cartel Linked To Several Murders In Nuevo Leon

"Sol Prendido" for Borderland Beat



State Public Security Secretary Gerardo Palacios Pámanes said that those arrested after a chase and armed confrontation could be responsible for several murders.

Five men were arrested in Apodaca and authorities link them to several homicides.

After municipal and state authorities arrested five members of a criminal group with a national presence following a chase that began in Escobedo and ended in Apodaca, Nuevo León Public Security Secretary Gerardo Palacios Pámanes reported that those involved were linked to several murders in the Monterrey metropolitan area and rural areas of the state.

Outside the Government Palace after the security meeting, Palacios Pámanes detailed that the confrontation between authorities and armed civilians left two policemen injured, although not seriously, in addition to a presumed criminal with a superficial wound in the shoulder.

"Escobedo police officers yesterday at approximately 11:00 p.m. were in pursuit of a white Audi vehicle, in which armed subjects were traveling. At some point during the pursuit these subjects opened fire on our municipal colleagues," said the secretary.

He added that during the deployment of the pursuit, municipal police from neighboring areas and elements of the Civil Force were also present.

Regarding the arrest, the authority pointed out that the men had tactical vests with the initials of a cartel with national presence, in addition to the possession of long arms, ammunition and caltrops.

"There are five detainees, one of whom has a gunshot wound in the shoulder, they were carrying tactical vests with the acronym of an organized crime group with national presence," he said.

Gerardo Palacios Pámanes, Secretary of Public Security of Nuevo León.

Regarding their relationship with homicides, Palacios Pámanes did not give details on what specific events are being linked to the detainees, but they are working with the Attorney General's Office to determine this.

What was the chase and confrontation through the towns of Escobedo and Apodaca like?

The arrest of five individuals and the wounding of two police officers were the result of an intense chase and shootout between Escobedo municipal officers and alleged members of organized crime on Tuesday night on the Libramiento Noroeste.

Following the incident, in the jurisdiction of Apodaca, authorities seized a vehicle carrying weapons, tactical vests and other items.

It all began moments before midnight on the Northwest Bypass near the road to Las Pedreras, close to the Santa Martha neighborhood.

There, the officers of the Escobedo Citizen Security detected the suspicious vehicle and signaled the driver to stop, but he ignored them and the pursuit began.

The pursuit, which was joined afterwards by more police officers, advanced towards Apodaca, from west to east, while the exchange of gunfire between the law enforcement officers and the alleged thieves intensified.

Once in Apodaca, on the road to Santa Rosa, the suspects' vehicle got out of control and abruptly entered a private lot, where the five men were captured.

In the operation, Escobedo authorities used a state-of-the-art drone, equipped with an infrared camera system, capable of detecting people in the dark.

Regarding the wounded policemen, it was reported that one of them suffered a gunshot wound in one hand, and the other suffered several wounds due to the collision of one of the patrol cars.

Tense Confrontation Between Güero Palma And Protected Witness Ensues

"Sol Prendido" for Borderland Beat


In a hearing that lasted approximately six hours, the confrontation and interrogation between the alleged drug trafficker Jesús Héctor Palma Salazar and the protected witness Marcelo Peña García, code name "Julio", took place within the proceedings against the Sinaloan for the murder of a former security chief of the Puente Grande prison.

The hearing, scheduled remotely via videoconference at 10:00 a.m., began shortly before 12:00 p.m. due to logistical issues and tight security measures in the court building annexed to the Jalisco Preventive Prison Commissariat, where the witness appeared under armed protection, while Palma was behind a computer screen from a call center in the maximum security prison of Altiplano, in the State of Mexico.

The point to be clarified in the hearing convened in the Second Court of Criminal and Integral Justice for Adolescents of the First Judicial District of Jalisco (traditional mixed criminal system) was the accusation that the protected witness "Julio" made about Güero Palma, on May 17, 2023, in the sense that it was the prisoner himself who confessed his alleged responsibility in the murder of the subdirector of security of Cefereso 2, Juan Castillo Alonso, a crime that took place on the night of December 3, 2000, in the municipality of Zapopan.

Inside and outside the courthouse there was a large number of security personnel from the State Prosecutor's Office, the Federal Ministerial Police attached to the Criminal Investigation Agency, the National Guard and the military. In the parking lot of Puente Grande, in addition to the regular patrols, there were two armored vehicles in which the witness transferred from Mexico City was guarded.

Through the screen, dressed in his khaki uniform, Jesús Héctor Palma despaired at the delay. He would get up from his chair, take a few steps and sit down again; however, when the hearing began, the inmate was calm. He was virtually face to face with his accuser, who was interrogated by Güero Palma's defense attorney, José Gabriel Martín Hernández Rodríguez, in the presence of the secretary of agreements, who acted as judge by operation of law.


OBJECTIVES

Marcelo Peña García, the "star" witness to keep the accused in prison, at all times boasted about his political familiarity with drug trafficker Joaquín Guzmán Loera, El Chapo, whom he referred to as "my brother-in-law" and in each answer to the questions of Palma's lawyer sought to fix ministerial statements made during 2001 against members of the Sinaloa Cartel.

The answers of the witness "Julio" led defense attorney Hernandez to cross-examine on those topics, finding opposition to his questions from the director of Prosecution Follow-up of the Jalisco State Prosecutor's Office, prosecutor Jaime Navarro Hernandez, who argued that "they were induced or biased questions" or "they were already answered in previous statements". This situation led the litigant to complain to the judge.

One of the first questions to Peña García was "How did you see Chapo? Marcelo answered "I saw him as a person of trust in Cefereso number 2. I took care of all his personal and family matters and acted as his private secretary. I had contact with friends and associates of his criminal organization that continued to operate from prison". Prosecutor Navarro interrupted to tell the witness to concentrate on what he was being asked, not to answer more than what he was asked.

After presuming that he was Chapo's messenger and private secretary for whatever he wanted, "Julio" was asked by Güero Palma's lawyer how he entered the Cefereso, and also what name did you have as a protected witness? Despite the fact that his pseudonym or password is public knowledge, Marcelo answered "I can't tell you". For his part, Jaime Navarro told the judge "What makes you think we are going to tell you the name".

After much insistence, Marcelo finally acknowledged that his code name is "Julio". The point was important because in many ministerial declarations and preliminary investigations, "Julio" has been considered a false witness. Then, the question that mattered: How did you find out about the murder of Commander Juan Castillo Alonso and why do you accuse Güero Palma? Peña answered "Look, I used to go to Cefereso 2 a lot, before the corruption started, then there was a lot of corruption...". Prosecutor Navarro repeated to the declarant not to say more than what he was being asked.

Peña García said about the accused's alleged responsibility: "I just greeted Güero by hand when I went to visit El Chapo's family, but we coincided in the dining room with the family visit, because Palma also had a visit. Later there was closeness and friendship. Because of his criminal association, he talked to me, to plan several things, among them the murders of Juan Pablo de Tavira and Juan Castillo.

Attorney José Gabriel Martín Hernández Rodríguez asked: "When you found out about the murder, what did you do? "I informed the bosses of the crimes, I gave them details of what I heard from Güero Palma and everything about how they did it. I told them who they sent, that it was two hitmen from Nuevo Laredo," said Marcelo, who said he was the first to know about the crimes "because the hitmen from Nuevo Laredo had to report to me. Because I was the person who visited Chapo the most. Chapo told me, you have to report to me first.


PROTECTED WITNESS

The lawyer’s inquiry returned to the subject of the protected witness, questioning "Julio" since when did he have this status before the Attorney General's Office (FGR), formerly PGR. Peña García said that he was a protected witness between 2001 and 2002, without remembering the month, because he was arrested in July 2001 and then he was given that protection by law. He added that this year he asked for protection when he testified in "a hearing in the Altiplano or in Pachuca, I don't even remember, but it was this year. At this moment I don't know if I am a protected witness or not, but I had already asked for it.

For this case it is relevant to know the status of "Julio" as a protected witness, it has been said that authorities pay him more than 100,000 pesos per month and have him protected in a bunker in Mexico City. "In 2001 it was proposed to me and I accepted to be a protected witness for my safety and my family, I reaffirmed the links that my brother-in-law El Chapo had with all his illicit businesses and I was afraid", said the man from Compostela, Nayarit.

What was his involvement in those illicit businesses? This was the next question asked to Marcelo Peña, but again the prosecutor Jaime Navarro Hernández objected to the question arguing that the witness had already answered it in another statement. Güero Palma's lawyer replied to the secretary acting as judge, "What was the point of the interrogation if they don't let me ask? "He is the one who is bringing up the issue of criminal association, he is bringing up the issue of protected witness, he is bringing up the issues... How can I not ask?"

Q&A. Why was he arrested? "Well, they were looking for Chapo and since they didn't find him, they arrested me". What were your obligations as a protected witness? "Well, I had to testify everything I knew about my brother-in-law El Chapo's criminal organization. What did this criminal organization do? Jaime Navarro again refuted the questioning.

In the arguments between the prosecutor and the defense, at one point, Peña Garcia wanted to get into the discussion, the court clerk reminded him that he was a witness and had to focus on what the defense was asking him, without intervening in the debates. "Ah well, yes, miss," said Chapo Guzmán's in-law. The ruckus between the lawyer and the Prosecutor's Office official was attended by the judge, who decided to resume the hearing after the abrupt interruption.

At 4:00 p.m., Palma's lawyer asked the witness: Why do you say that my client Jesús Héctor Palma Salazar is the mastermind for the murder of Commander Castillo Alonso? Suddenly, from the other side of the screen, Güero Palma said "I don't know you", addressing Marcelo, who responded violently "I wish you had the balls to admit it. Don't play dumb ass. Have some fortitude. You said it in prison every time I came to visit".

Attorney Jose Gabriel Martin Hernandez asked the judicial authority "Please put order in the court. You are offending my client. And my client has been very polite during the entire hearing and has not offended Mr. Marcelo at any time". The atmosphere became tense in the courtroom and the secretary acting as judge decided to suspend the hearing, which will be resumed according to the agendas of both the court and the Altiplano prison, which could happen in weeks or months.


SEARCH

Jesús Héctor Palma filed an injunction since June against the indictment issued in criminal case 9/2023 for his alleged responsibility in the commission of the crime of aggravated homicide against commander Juan Castillo Alonso. The trial of guarantees continues in the Third District Court of Amparo in Criminal Matters in the State of Jalisco, with residence in Zapopan, where the interested third party, the indirect victim, Juan José Castillo Ochoa, son of the deceased, has been summoned.

The order to summon the heir of the direct victim to the trial was issued in an agreement dated July 10 of this year; however, as of this date, the person has not been located, the amparo judge also ordered an unsuccessful search in the municipalities of Zapopan, Tonala and Tlajomulco de Zuñiga, in Jalisco; Manzanillo, Colima; Nezahualcoyotl, in the State of Mexico; and in Nuevo Leon.

Due to the fact that Castillo's son has not appeared in the amparo proceeding, the federal judge ordered the summons to be served by means of edicts at the expense of the Federal Treasury, "which must contain a brief description of the claim and be published three times, seven days at a time, both in the Official Gazette of the Federation and in one of the most widely circulated newspapers in Mexico, with residence in Mexico City, Once the last publication has been made, the interested third party in question has a term of thirty calendar days to appear in court by himself or through his authorized representative or legal representative".

On the other hand, the legal team of the plaintiff Palma Salazar offered some evidence to refute the accusations made by the protected witness against his client, and requested the district judge to require the federal penitentiary authorities "the interior and exterior security protocols and procedure manuals, whether for visits by relatives or other persons, as well as for the entry of attorneys and defense attorneys; that have been established for the Federal Centers of Social Readaptation, in the period from 2000 to 2001".

Also offered was "the Planimetral Map, also called sketch, of the interior of the disincorporated Federal Center for Social Readaptation number 2, "Occidente". Logbooks for visits (family, friends and defense attorneys) found in the file of the now disincorporated Federal Center for Social Readaptation number 2, "Occidente", in relation to Mr. Marcelo Peña García, from October 2 to 18, 2000".

And finally, "Filling logs for the security elements of the penitentiary center found in the file of the now disincorporated Federal Center for Social Readaptation number 2, "Occidente", which were made from October 2 to 18, 2000, in the areas of social work, access to the communication area where the call centers and family visitation rooms are located, in addition to the logs found at the entrance of dormitory A, which is made up of modules one through four".

The amparo court reserves the right to provide the evidence offered "until such time as the interested third parties are duly summoned, that is to say that the constitutional litis is duly established and to be in a position to provide what is appropriate".

THE HOMICIDE

The murder against the former deputy director of internal security of Cefereso 2, in Puente Grande, Jalisco, was perpetrated on the evening of December 3, 2000 at his home in the Haciendas del Valle neighborhood, in the municipality of Zapopan, when he was resting. Armed men knocked on Juan Castillo Alonso's door, on Hacienda Las Gardenias street, and entered the house to shoot him four times, and he died later at the Cruz Verde Zapopan.

The murderers fled aboard a cab, which had a theft report, a unit that was abandoned in the parking lot of the Plaza San Isidro shopping center, on the highway road of the Guadalajara Metropolitan Zone.

Juan Castillo had served as head of custodians of the federal prison until February of that same year, when he resigned after many years of service in the state prison of Almoloyita, in Cefereso 1 "Altiplano", and in the maximum security prison located in El Salto, Jalisco, where he was always considered an energetic public servant, and upon the arrival of new commanders from Sinaloa, he was removed and preferred to retire.

The crime remained unsolved for 22 years by the Jalisco State Attorney General's Office (now the Prosecutor General's Office). It was the former Attorney General's Office (PGR), through the Specialized Sub-Attorney General's Office for Investigation of Organized Crime (SEIDO), which obtained a testimony that compromised Palma Salazar. The protected witness Marcelo Peña García, with the code name "Julio", was the one who testified that he knew that Güero Palma ordered the murder of Juan Castillo.

Days before the murder of the head warden, the former director of the "Altiplano" prison and former director of the Federal Judicial Police, Juan Pablo de Tavira Noriega, was murdered in a restaurant of the Autonomous University of the State of Hidalgo, a matter for which Jesús Héctor Palma, who at that time had not been in that federal prison in the State of Mexico, is also being linked. Güero Palma Salazar is currently imprisoned in that Cefereso, in Almoloya de Juárez.
