María Claudia Tarazona, the widow of assassinated Colombian Senator and presidential candidate Miguel Uribe Turbay, announced on October 14, 2026, that she has formally handed evidence over to federal prosecutors indicating the order to kill her husband originated inside the nation’s Congress. Speaking in a broadcast interview with Noticias Caracol, Tarazona also stated that the materials she provided to Colombia’s Office of the Attorney General (Fiscalía) suggest the funding for the June 2025 assassination came from Venezuela, and she urged authorities to investigate the killing as a potential state crime.

The explosive allegations have triggered immediate institutional and political repercussions in Bogotá. While leaders of Uribe Turbay’s conservative Centro Democrático party demanded an immediate inquiry into the legislative branch, investigative reporting notes that prosecutors have not publicly corroborated the claims, and former lawmakers from the Comunes party have pushed back against attempts to link them to the crime.

The Alleged Warnings and the State Crime Hypothesis

According to El Colombiano, Tarazona stated that she received messages on her mobile phone warning of a coordinated plot targeting her husband and potentially other presidential hopefuls from the Centro Democrático party. She told interviewers that an unnamed source provided information stating that “the money came from Venezuela and the order came from Congress.” Tarazona said she turned over names, photographs, and message logs to the Fiscalía following formal evidentiary protocols.

As reported by El Espectador, Tarazona also disclosed that she has spoken directly with Attorney General Luz Adriana Camargo Garzón regarding a line of inquiry treating the assassination as a state crime—a legal classification suggesting that officials within the national government or state apparatus could bear responsibility. Tarazona argued that attributing the assassination solely to the Segunda Marquetalia, a dissident faction of the former FARC guerrilla movement led by alias “Iván Márquez,” is “a very vague statement” that addresses only the material execution of the attack rather than the intellectual authors who ordered and financed it.

In her public remarks, Tarazona also emphasized the importance of obtaining testimony from alias “Araña,” a leader of the Comandos de Frontera armed group who was extradited to the United States by President Abelardo de la Espriella. President de la Espriella, speaking at a commemoration event for Uribe Turbay the week prior to Tarazona’s interview, publicly stated that he shared the view that the assassination constituted a state crime and pledged that the killing would not go unpunished under his administration.

Political Fallout and Disputed Links to the Comunes Party

Tarazona’s statements included an allegation from the unverified tip that a member of the Comunes party—the political organization formed by demobilized FARC combatants following Colombia’s 2016 peace accord—was connected to the plot. That claim drew sharp reactions across the political spectrum.

On October 14, Senate President Honorio Henríquez, a member of the Centro Democrático, sent an official letter to Attorney General Camargo requesting an urgent and thorough investigation into Tarazona’s disclosures. According to an official release from the Senado de la República de Colombia, Henríquez pledged the legislature’s full institutional cooperation while underscoring that the Fiscalía is the competent authority to verify the claims and determine criminal liability. “If someone from Congress turns out to be implicated, the full weight of the law must fall upon them,” Henríquez wrote, as quoted by El Espectador.

Other conservative figures echoed the call. Centro Democrático Senator Hernán Cadavid described the complaint as grave and criticized the peace agreement that granted congressional seats to former guerrillas, while former President Álvaro Uribe called for full state protection for Tarazona and a complete uncovering of the truth.

However, the allegations remain unverified leads rather than established prosecutorial findings. According to reporting by El País, as of October 15, there is no publicly established evidence implicating Comunes legislators in the assassination or linking them to the dissident guerrilla faction identified by investigators as the material perpetrators. Meanwhile, El Tiempo reported that former Comunes senators—including Julián Gallo, Pablo Catatumbo, Sandra Ramírez, and Omar Restrepo—issued a formal response pushing back against Tarazona’s statements linking their party to the assassination.

Current Status of the Criminal Investigation

While the identity of the ultimate masterminds remains the central open question in Colombian politics, prosecutors have already secured seven convictions against the operational cell that carried out the June 2025 attack.

According to case details reported by El Colombiano, six adult defendants pleaded guilty and received prison sentences exceeding 20 years: Katherine Andrea Martínez (alias “Gabriela”), Carlos Eduardo Mora González (alias “El Veneco”), Simeón Pérez Marroquín (alias “El Viejo”), Harold Daniel Barragán Ovalle (alias “Harold”), Elder José Arteaga Hernández (alias “El Costeño” or “Chipi”), and William Fernando González Cruz (alias “El Hermano”). In addition, the teenager who fired the shots at Senator Uribe Turbay was sentenced to seven years of juvenile detention.

Among those convicted, prosecutors identified Simeón Pérez Marroquín, who received a sentence of more than 22 years in prison, as a key intermediary between the operational hit squad and the individuals who ordered the assassination. Testimony from the convicted participants has enabled investigators to reconstruct the logistics of the shooting, though the Fiscalía has not yet issued an official public statement confirming whether the materials submitted by Tarazona have been authenticated or formally incorporated into a new prosecutorial indictment.

What It Means for Colombian Governance and Justice

For Colombian citizens and political observers, the controversy highlights the deep polarization surrounding the country’s security apparatus and the legacy of the 2016 peace process. An allegation that a sitting or former member of Congress helped orchestrate the killing of a prominent opposition senator—and that foreign funds from Venezuela were used—carries profound implications for institutional stability and diplomatic relations.

At the same time, legal standards require that such high-stakes accusations be substantiated through verifiable evidence in court. As Tarazona herself acknowledged in her remarks, it is now the responsibility of the Fiscalía to corroborate the tips she received and determine whether the evidence supports criminal charges against any state or legislative actors.
