Colombia’s Prosecutors Go After FARC Dissidents “Segunda Marquetalia” For Presidential Candidate Miguel Uribe Turbay Murder

So far, three people have been convicted in the killing of former presidential candidate Miguel Uribe Turbay, while arrest warrants target seven members of FARC dissident factions.

Colombia’s Attorney General’s Office is advancing its investigation into the assassination of Senator and presidential pre-candidate Miguel Uribe Turbay. On one hand, it sentenced alias “El Viejo” to more than 22 years in prison for acting as an intermediary between those who ordered the crime and the criminal network that carried out the attack; on the other, it issued arrest warrants for seven individuals belonging to a dissident faction of the FARC accused of ordering the killing.

The assassination of the Centro Democrático party senator and presidential candidate took place on June 7, 2025, in Bogotá while he was participating in campaign-related activities. The attack was carried out by a 14-year-old who fired multiple shots and was immediately captured after an exchange of gunfire with National Police officers and Uribe Turbay’s security team.

General attorney, Luz Adriana Camargo Garzón said the crime was not “an isolated act, but the result of a structured criminal operation that involved both an urban criminal network operating as outsourcing and an organized armed group” known as the “The Segunda Marquetalia.”

Miguel Uribe Londoño, a presidential candidate and the victim’s father, said in a tweet directed at President Gustavo Petro: “President @petrogustavo You harassed Miguel with your verbal abuse, making him a target for assassination. Your government failed to protect him. Your government has been tolerant of drug trafficking, and the criminals who benefited from your total peace used the Second Marquetalia to assassinate Miguel. But the masterminds behind this must continue to be sought within the Colombian government. We cannot continue to accept this violence. This is why Miguel’s legacy needs to be upheld in the Presidency, and I will carry it until the last day of my life.”

Presidente @petrogustavo.

Usted hostigó a Miguel con su violencia verbal poniéndolo como carne de cañón para que lo asesinaran.

Su gobierno no le dio protección.

Judicial developments and convictions

According to the Attorney General’s report, three individuals have already been convicted through plea agreements:

1. Simeón Pérez Marroquín, alias “El Viejo,” identified as the link between those who ordered the crime and the criminal network, was sentenced on March 20 to 22 years and four months in prison.
2. Carlos Mora González, who conducted surveillance at the attack site and transported other suspects, was sentenced to 21 years in prison.
3. Katherine Andrea Martínez, who took part in planning meetings and retrieved the weapon used (a Glock pistol), was sentenced to 21 years and two months in prison.

The 14-year-old who carried out the attack was sentenced under Colombia’s Juvenile Criminal Responsibility System.

Criminal network and FARC dissident involvement

After nine months of investigation, prosecutors established the involvement of the dissident FARC faction known as The Segunda Marquetalia as the group that ordered the crime and issued arrest warrants against several of its alleged leaders and members.

According to the statement, those targeted include Kendry Téllez Álvarez, identified as a possible mastermind; Iván Luciano Marín Arango, alias “Iván Márquez”; Géner García Molina, alias “Jhon 40”; Alberto Cruz Lobo, alias “Enrique Marulanda”; Jhon Jairo Bedoya Arias, alias “Rusbel”; Diógenes Medina Hernández, alias “Gonzalo”, and José Aldinever Sierra Sabogal, alias “Zarco Aldinever”.

They face charges of aggravated homicide, conspiracy to commit a crime, and the manufacture, trafficking, possession or carrying of firearms, accessories, parts or ammunition.

Additionally, according to El Colombiano, authorities are offering a reward of up to $5 billion Colombian pesos (around $1,4 million USD) for information leading to the capture of alias “Iván Márquez”, and $4 billion Colombian pesos ($1,2 million USD) for alias “Jhon 40” and “Zarco Aldinever”, identified as key leaders of the group.

“Wanted dead or alive”

According to El Colombiano, “the inclusion of ‘Zarco Aldinever’ on the most-wanted list has raised questions, as he had reportedly been killed in August 2025 in alleged clashes with the National Liberation Army (ELN) guerrilla group”

“He is alive; that is, we have no evidence that he is dead. For us, “Zarco Aldinever” is alive. There is no corroborated evidence regarding the rumor that he was killed by the ELN. It remains a rumor, which is why the arrest warrant was issued,” the attorney general said.

Meanwhile, the whereabouts of Iván Luciano Marín Arango, alias “Iván Márquez”, one of the former negotiators of the 2016 peace agreement who later returned to armed activity, remain unknown. He has been reported dead on several occasions, most recently in July 2023, when it was speculated he had died from gunshot wounds in Venezuela.

However, the government has not confirmed those reports. “Despite intelligence efforts by the security forces, there is no reliable information to determine his whereabouts or status,” Defense Minister, Major General (ret.) Pedro Arnulfo Sánchez said.
