Gutiérrez’s communication highlights a public event held on June 21, 2025, in Medellín titled “A Pact for the Urban Peace of Medellín,” which was promoted by the Presidency of the Republic of Colombia. During the event, nine individuals identified as leaders of criminal organizations were brought onto a stage and presented as “peace spokespersons.”

The mayor’s letter notes that these individuals have firm convictions for various crimes, including homicide, narcotics trafficking, forced disappearance, and extortion. Among those present were Juan Carlos Mesa Vallejo, alias “Tom,” and Freyner Alfonso Ramírez García, alias “Pesebré,” both of whom are on the Specially Designated Nationals and Blocked Persons List maintained by the US Department of the Treasury‘s Office of Foreign Assets Control (OFAC).

The letter also states that the release of these individuals from the Itagüí prison was not authorized by a judge. It further alleges that the release was requested by Senator Isabel Cristina Zuleta López of the Pacto Histórico political coalition. Senator Zuleta defended her actions in a statement to W Radio, asserting that it was “inexplicable” not to include the leaders of the criminal structures in a public dialogue about urban peace, as they had been recognized by the president for such talks.

Criminal Structures and Transnational Ties

The letter details the history of criminal organizations in Medellín, from the Medellín Cartel of the 1980s to modern-day groups. It names several prominent organized crime groups (G.D.O.s), including “El Mesa,” “Los Chatas,” “Pachelly,” and “La Terraza,” stating that they continue to operate international narcotics trafficking networks.
Gutiérrez’s letter alleges that these Colombian criminal structures have alliances with international organizations such as the Tren de Aragua, Cártel de Jalisco Nueva Generación, the Sinaloa Cartel (OTCMKTS: SRBAL), and the Albanian Mafia, among others.

Information Leak at the Attorney General’s Office

In his letter, Gutiérrez also raised concerns about alleged irregularities within the Colombian Attorney General’s Office. He claims that an investigation into Juan Pablo Taborda Samora, alias “Yordi,” and Daniel Muñoz Olaya, the son of criminal leader José Leonardo Muñoz Martínez, alias “Douglas,” was compromised. According to the letter, information regarding an impending arrest operation against Daniel Muñoz was allegedly leaked, preventing his capture. This alleged leak informed “Douglas” of the ongoing investigation against his son, allowing them to evade authorities.

Subject: Submission of relevant information regarding the critical security situation and transnational criminality in Medellín, Colombia.

I, Federico Gutiérrez Zuluaga, in my capacity as Mayor of the Special District of Science, Technology, and Innovation of Medellín, identified with NIT 890.905.211-1, respectfully address you to express profound institutional concern over recent events that, stemming from the national policy of the current Colombian Government, are allegedly favoring, directly and indirectly, criminal structures that have historically affected the security of both our city and that of its international allies, among them, the United States of America.

As is widely known by the international community, Medellín has a complex history linked to organized crime. Indeed, from the 1980s, when the Medellín Cartel dominated the global drug trade, to the present day, the city has been a strategic hub for transnational criminal activities. The criminal structures that mutated from a centralized model to fragmented yet interconnected networks, such as the self-styled “Oficina de Envigado” and the current Organized Crime Groups (hereinafter G.D.O.) and Organized Common Crime Groups (hereinafter G.D.C.O.), maintain a very high criminal capacity with international reach.

Today, the 10 G.D.O.s present in Medellín and the Aburrá Valley—among them “El Mesa,” “Los Chatas,” “Pachelly,” “La Terraza,” “Robledo,” and “La Sierra”—and G.D.C.O.s such as “San Pablo” and “La Oficina del Doce,” continue to operate international narcotics trafficking networks with destinations primarily in North America and Europe. These structures maintain active alliances with cartels such as the “Tren de Aragua”, “CJNG”, “Sinaloa Cartel”, “Albanian Mafia”, “Choneros”, “Lobos”, “Cartel de los Soles”, “Maras Salvatruchas”, “Ndrangheta”, “Camorra”, among others, which demonstrates the internationalization of their criminal activities.

Despite this grave and evident reality, the current National Government of Colombia, led by President Gustavo Petro Urrego, has promoted a policy that, under the discourse of “Total Peace,” has publicly legitimized criminal leaders with serious judicial records, many of whom are apparently still active in drug trafficking, exploitation of minors and adolescents, arms trafficking, human trafficking, and other illegal revenues of transnational interest.

Thus, on this past June 21, 2025, during the public event called “A Pact for the Urban Peace of Medellín,” which was promoted by the Presidency of the Republic of Colombia, nine (09) of the top leaders of these structures¹, among them individuals included on the OFAC (Office of Foreign Assets Control) List such as Juan Carlos Mesa Vallejo (alias “Tom”) and Freyner Alfonso Ramírez García (alias “Pesebré”), were displayed on stage as “peace spokespersons,” despite having firm convictions for atrocious crimes (such as homicide, narcotics trafficking, use of minors for the commission of crimes, forced disappearance, extortionate kidnapping, extortion, and criminal conspiracy, among other crimes of extreme gravity) and even though, apparently, they continue to control their criminal structures from the penitentiary center where they are imprisoned (particularly, in the Itagüí prison – Antioquia). This event was also attended by the Minister of Justice and Law (Eduardo Montealegre Lynett), the Minister of the Interior (Armando Alberto Benedetti Villaneda), the Minister of National Education (José Daniel Rojas Medellín), the Minister of Labor (Antonio Sanguino Páez), the Minister of Mines and Energy (Edwin Palma Egea), the Minister of Cultures, Arts and Knowledge of Colombia (Yannai Kadamani Fonrodona), Senators of the Republic Isabel Cristina Zuleta López and León Fredy Muñoz Lopera, Representatives to the Chamber for Antioquia Alex Xavier Flórez Hernández and Pedro Baracutao García Ospina, the Representative to the Chamber for Valle del Cauca Alfredo Mondragón Garzón, and the former mayor of Medellín, now charged by the Office of the Attorney General of the Nation for alleged acts of corruption, Daniel Quintero Calle, among others.

Now, this public act signified a grave institutional violation. This, since it was an act of re-victimization for the people affected by these criminal groups, who have seen their victimizers legitimized in a political setting, without authorization from a Judge of the Republic to leave their place of imprisonment, even though they all currently have a final conviction (and it is being served). Likewise, the departure from the prison was supported by a request from the Historic Pact senator, Isabel Zuleta Cristina Zuleta López.

The foregoing raises serious questions about the separation of powers, due process, and the principle of equality before the law, given that, under the current legal framework, there is no legal basis for reaching an agreement with criminal structures, which does not amount to a submission to justice.

Furthermore, the foregoing occurred in a complex context, not only local but also national. This is because there have apparently been undue leaks of sensitive information and possible undue pressure in high-impact processes, namely:

In events surrounding recent procedural actions carried out by the Attorney General’s Office in the country against members of the G.D.O. “La Terraza,” among them Mr. Juan Pablo Taborda Samora, known in criminal jargon as “Yordi” (the top leader and boss of hitmen for said organization), and against Daniel Muñoz Olaya, son of José Leonardo Muñoz Martínez (alias “Douglas”), arrest warrants were issued against them for different crimes which they apparently took part in to integrate said criminal organization, who, according to the Prosecutor’s Office, are involved in money laundering and illicit enrichment. However, despite details of this operation having been filtered by irregular third parties, which could have jeopardized the success of all the captures (apparently alerting the targets before the proceedings began), and compromising the security of the Judicial Police investigators and the designated prosecutor’s office itself.

Indeed, as was evidenced in an extraordinary security meeting held in the District of Medellín this past June 17, 2025 (which included the participation of the Unit Against Organized Crime of the Attorney General’s Office, the National Police, the National Army of Colombia, the Colombian Air Force, and representatives of state intelligence agencies) and in a meeting on June 19, 2025 aimed at conducting a presentation of the balance of operational results by the National Police, it was established that there was a leak of information hours before the operation, since alias “Douglas” had been informed of a respective investigative process against his son and that his capture would be imminent.

As a result of this situation, not only would the capture of Daniel Muñoz Olaya have been prevented (by evading the action of the public force at the time of the execution of the search with (Additional text appears to be missing beyond this point.
