Segunda Marquetalia ordered the attack last year according to trial testimony.

Revelations that former FARC leaders ordered the 2025 killing of Miguel Uribe have heightened political tensions in the run-up to the May presidential elections.

The 39-year-old Colombian senator and presidential hopeful was gunned down by a Bogotá gang hired by the Segunda Marquetalia, an armed group created by disgruntled guerrillas hiding in Venezuela, according to testimony revealed in court.

The senator was shot down by a 15-year-old assassin at an open-air political rally in the barrio of Modelia in June, 2025. Uribe died of head wounds two months later.

After months of investigations and multiple arrests, state prosecutors were last week finally able to link the local gang that carried out the hit with the armed group.

The breakthrough came during the trial of Bogotá-based gang leader Simeón Pérez Marroquín, also known as ‘El Viejo’, who admitted he had hired the local Plata o Plomo (‘Silver or Lead’) gang to carry out the killing on behalf of the Segunda Marquetalia armed group.

“The deal was that they would pay one billion pesos [US$270,000] for the senator’s death,” said Marroquín in a statement reported by magazine Semana.

Right hand man

Confirmation of involvement by an armed group founded by former FARC leaders sparked a political spat between front-runners for the upcoming presidential election.

Right-wing candidate Paloma Valencia was quick to accuse the Petro government of negotiating peace with the Segunda Marquetalia – even while the armed group was plotting the murder of Uribe.

Valencia referred to Marroquín’s statements that the hit was organized by veteran guerrilla Zarco Aldinever, the right-hand man of the group leader Iván Márquez, in early 2025.

At this time Aldinever was nominated a ‘peace manager’ by the Petro government, meaning any arrest warrants were suspended and the rebel was free to roam. This despite the collapse of peace talks with the Segunda Marquetalia at the end of 2024.

Valencia further pointed to the closeness between her main election rival Iván Cepeda and leaders of the armed group.

Old photo

“The killer of Miguel Uribe is photographed hugging Iván Cepeda,” she wrote on X, attaching  a photo of her rival with Segunda Marquetalia founder Iván Márquez.  

In fact, the photo of Cepeda dated from the 2016 FARC peace talks, explained President Petro in a strongly worded statement defending his friend and political ally.

“The photo shows Iván Cepeda’s attempt to help [the Santos government] achieve peace. At that time, the entire FARC was ready for peace,” said.

Iván Márquez was number two in the FARC at the time and widely respected for his role in the negotiations.

Petro went on to blame his predecessor, right-wing president Iván Duque, for undermining the FARC peace process that forced former guerrilla leaders like Márquez back to arms and the Segunda Marquetalia.

Following the 2016 deal, some former FARC leaders had been “entrapped by state prosecutors with fake drug charges”, he said, leading to extradition requests from the United States.

Faced with this legal pressure several top commanders, including Iván Márquez and Jesus Santrich, fled to Venezuela in 2018 before emerging on video a year later to announce their new incarnation as the Segunda Marquetalia, named after the village in the Tolima department where the original FARC first formed in 1964.

The armed group was active in drug trafficking and illegal mining along the Colombia-Venezuela border, in the departments such as Vichada and Guainía, according to a profile by InsightCrime. The leadership is suspected of hiding out in Venezuela.

Another study by Fundacion Ideas para La Paz estimated the group to have 530 armed combatants in 2025, an increase of 15% on 2024, and work mostly in the eastern plains of Colombia.

A hunt is on

In a press conference on Tuesday, Valencia accused Cepeda and other left-wing lawmakers of backing the former FARC commanders in their legal battles back in 2018, creating a chain of events leading to the creation of recycled armed group.

“Congressmen like Cepeda defended [Marquéz and Santrich] …and didn’t allow them to be extradited. If these thugs had been extradited, Miguel Uribe would be alive today,” she said.

In his own press statement Cepeda called Valencia’s comments “a dirty political game” and issued a challenge to the candidate, and her political mentor right-wing former president Álvaro Uribe, to back up the accusations in court.

“It’s infamy to accuse me or President Petro to have any type of involvement in such a deplorable deed as the assassination of senator and presidential pre-candidate Miguel Uribe,” he said.

Meanwhile this week the Colombian attorney general’s office launched a fresh hunt for the leaders of the Segunda Marquetalia, offering around million-dollar rewards for the capture of seven commanders including Iván Márquez and Zarco Aldinever.  

In fact, Aldinever was reported killed by rival armed group ELN in Venezuela during a squabble over a cocaine shipment in August last year – the same month that Miguel Uribe died – according to Colombian state forces at the time.    

This week Colombia’s Minister of Defense Pedro Sanchez walked back that claim saying no body had ever been found and that the initial report of Aldinever’s death – sent from the Segunda Marquetalia itself – could be disinformation.

“At this time, the position is clear: without a body there is no confirmation of death, and that is why all institutional resources remain active to locate him,” said Sanchez.

Underworld connections

Closer to home, the Segunda Marquetalia’s influence in Bogotá was under scrutiny after Simeón Marroquín’s testimony shed light on the murky connections with the city’s underworld.

Marroquín admitted that in previous decades he had acted as an urban operative for the FARC guerrillas, a hired gun ready to carry out orders in the city.

“I never wore camouflage, but while I was here in Bogotá, I was a miliciano. Guerrilla missions would come up, and I’d carry them out, but I was never in the ranks.”

His contacts with the FARC continued to the Segunda Marquetalia that tapped him for the Uribe killing.

Early in 2025, Marroquín was invited to a secret meeting in Cúcuta close to the Venezuelan border where, according to his testimony, Aldinever offered him one billion pesos for the crime (US$270,000) and another 600 million pesos (US$160,000) to “bribe the justice system” to deflect attention from the guerrilla group.

The motive for the killing was not clearly revealed by Marroquín, though a text message later found on his phone sent to his guerrilla paymasters talked of an “eye for an eye”, suggesting the former rebels were out for revenge.

Chilling revelation

Uribe was selected as an influential senator, scion of a right-wing political family, and popular candidate for this year’s presidential elections. He was also an easy target for assassins with his regular visits to communities where he had walkabouts to engage with local voters.

In the first few months of 2025, Marroquín worked his underworld connections to hire the Plata o Plomo gang which in turn lured the 15-year-old gunman who shot and wounded Miguel Uribe in a small park in the barrio of Modelia on June 7.

Marroquín’s account paints a picture of a loose network of petty criminals lured by cash rather than political interests, ignorant of the details of both their intended target and the paymasters behind the plot.

The middleman saw the hit as a “good business opportunity” but also a chance to rekindle his role as urban operative for a guerrilla organization.

Marroquín’s plan unraveled after the 15-year-old gunman and various low-level gang members were detained in the hours and days following the June attack, creating a trail leading to his own capture in October.

“What’s done is done”

One chilling revelation was the order from above for Marroquín to kill low-level gang members to cut links to the guerrilla masterminds. This included murdering alias Gabriela, who transported the weapon and was present on the day of the shooting.

Marroquín refused to kill Gabriela, telling investigators “I didn’t have the heart for that because she was very young.” But he did send her by bus to the city of Florencia where the guerrillas were lying in wait.

The 19-year-old never made it; police investigators, already on Gabriela’s trail, organized for the bus to “break down” some miles before Florencia. Her arrest there and subsequent interrogation lead to Marroquín’s capture and eventual exposing of the links to the Segunda Marquetalia.

Last week, during the court process, Simeón Marroquín attempted to apologize for his role in the killing of Miguel Uribe.

“There are no words to justify my actions, but what’s done is done,” he said on camera from his cell, addressing his victim’s family – Uribe was married with four children – and asking forgiveness. He was then sentenced to 22 years in prison.

How quickly Colombian investigators can find Zarco Aldinever or other Segunda Marquetalia commanders, dead or alive, or hiding in Venezuela, remains to be seen.

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.

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.

Nine months after the shooting of presidential candidate Miguel Uribe Turbay in a leafy Bogotá park, the gang behind the killing have been rounded up and are facing justice.

The masterminds, though, are still at large. Circumstantial evidence points to a political assassination called in by an ex-FARC faction called the Segunda Marquetalia. But other theories exist.

And as the country prepares for the next rounds of elections, the youthful Uribe – seen by many as a presidential hopeful – is conspicuous by his absence.

We look back at killing that rocked Bogotá in 2025, and who might be behind it.

How did the shooting unfold?

Uribe was gunned down in Parque El Golfito, a green space in bustling Modelia on the western edge of Bogotá, on June 7, during a walkabout in the barrio where he met local business owners and climbed on a beer crate to deliver an impromptu address to a small crowd.

The senator was shot at close range twice in the head by a 15-year-old gunman wielding a Glock pistol in the crowd, who then fled but was himself shot in the leg by Uribe’s protection squad and captured in a nearby street.

Uribe was hospitalized and underwent several emergency surgeries before dying from his wounds on August 11, more than two months later.

Who was Miguel Uribe?

The 39-year-old senator was nationally recognized and scion of a political family. His grandfather Julio César Turbay was president from 1978 to 1982, and his mother the journalist Diana Turbay kidnapped by the Medellín cartel in 1991 who died in a botched rescue attempt, a tragedy immortalized by Gabriel García Márquez in his non-fiction book News of a Kidnapping.

Even though he was raised as a legacy politician, and a key candidate for the right-wing Centro Democratico, Uribe nevertheless garnered support across the political spectrum for his hard work and attention to detail, more technocrat than populist, and potentially a unifying figure.

It was perhaps typical of Uribe that the day he was shot he in an unsung corner of the city meeting everyday folks.

What was the impact of his assassination?

Many mourned the loss of the young senator, married with four children.  In reality, Uribe’s death was just one of many in Colombia during 2025 with 187 social leaders and human rights defenders murdered nationwide, according to data from conflict thinktank Indepaz.

The senator’s killing had an outsized impact for several reasons. First, Bogotá, unusually for a megacity, has almost half the homicide rate than many smaller cities and some rural areas with long-running conflicts between gangs and armed groups.

Secondly, the many feared Uribe’s attack signaled a return to the 1980s when a wave of political killings – usually by extreme right-wing forces against left wing targets in cahoots with drug cartels – plagued Bogotá and many other Colombian cities.

But united condemnation of the attack quickly degenerated to finger-pointing between political factions with Uribe’s lawyer filing a complaint against President Gustavo Petro for alleged “harassment” of the senator.

Was Petro to blame?

An early theory floated by the late senator’s lawyer was that the attack was a “hate crime”, which in Colombia covers persecution for ideological views. The argument went that Petro crossed the line with his itchy Twitter finger: in their complaint the lawyer presented a 20-page document with 42 presidential tweets disparaging Uribe. 

While acknowledging that Petro was in no way linked to the physical attack, he had created a “favorable environment” for anyone with a serious grudge to take out the senator, said the lawyers, though this didn’t explain why a 15-year-old – not a likely candidate for political grievances – was coerced to pull the trigger.

And by the end of June new evidence emerged from the shooter himself. The youth didn’t even know who his target was the senator, or indeed who was Miguel Uribe.

And other pieces of the puzzle fell into place, clarifying that the shooter was hired for cash by an organized criminal gang that had planned the killing in detail.

If it was so well planned, why did they get caught?

Good question. The contract killers calling themselves Plata o Plomo (‘Silver or Lead’) left a trail of evidence starting with the wounded gunman captured with minutes of the shooting.

Next to fall was Carlos Mora, alias ‘El Veneco’, who drove the young assassin, followed a few days later by 19-year-old Katherine Martínez, alias ‘Gabriela’, who delivered the pistol.

Gabriela’s arrest gave the first clues to a wider conspiracy: the webcammer was tracked down to the regional capital of Florencia, Caquetá, a jungle department of Colombia with high presence of armed groups.

CCTV footage from Modelia placed her inside the car with the gunman, and she later confessed to transporting the gun itself.With CCTV footage, and information from Gabriela and El Veneco, other key members of the gang were soon rounded up including two other getaway drivers and a middleman for hiring the 15-year-old.

Seems like a very amateur operation…

Plata o Plomo was a loose group of criminals drawn from the Bogotá underworld, and many had worked together before. The leader was Elder José Arteaga, alias Chipi, who in a rather unlikely twist also ran a hair salon in Engativá.

When not trimming beards, Chipi was immersed in crime with a history of extortion, violence and armed robbery, and was  linked to the murder of a Mexican businessman in Medellín in 2024.

See also: Arrests made but still questions in Uribe shooting.

He was also quite ruthless: according to Gabriela, Chipi was planning to cover his tracks by killing both El Veneco and the 15-year-old hired assassin. Being captured early likely saved their lives.

Chipi himself became the subject of a national manhunt until his luck ran out on July 5. He was captured hiding in a house in Engativá by a special police unit a month after the shooting, just a few kilometers from where it took place.

So, case closed?

Not so fast. Chipi was just one link in a longer chain. According to Gabriela, now a key witness, the hairdresser  told her the murder contract was for 700 million pesos, around US$190,000.

This amount of cash pointed to a bigger player. 

In Colombia there are plenty of candidates to choose from, and no shortage of pundits to point the finger.

Examples please?

Sure. Journalist and presidential hopeful Vicky Dávila accused Iván Mordisco, commander of the Estado Mayor Central – EMC – a dissident FARC faction fighting the state in the southwest of the country. She claimed to have insider information from military intelligence that also pointed to the likelihood of more assassinations of right-wing figures.

Her theory was backed by interior minister Armando Benedetti, who also saw reason for the EMC to stir up trouble in Bogotá as revenge for the war being waged against the group in Cauca.

However, no direct evidence was presented, and that the EMC denied any involvement, calling the allegations “a media strategy”.

Petro claimed involvement by the mysterious “Board”, a mythical super-cartel fused from drug gangs, guerrillas and paramilitaries. Petro portrayed himself as another potential victim: The Board was also plotting his own assassination, he said.

Wow. Anyone and everyone could have done it.

Exactly. Pick the political flavor of your favorite conspiracy.  More fanciful pitches were that the extreme right had planned it themselves to stoke a coup against Petro – who would likely get the blame – and at the same time eliminate the popular Uribe from the candidate’s list.

Or that the extreme left wanted to take out an effective political opponent from the presidential race.

One problem for investigators was the complex networks between criminal gangs, drug cartels and guerrilla groups, partly worsened by Petro’s Total Peace plan which had split armed groups into smaller and more dangerous factions.

The Plata o Plomo gang was clearly working for financial gain. But despite capturing eight members by the end of August, the important detail of who paid them – and why – was yet to be revealed.

Maybe the gang was scared to reveal the backers?

Quite likely. In the dog-eat-dog world of Colombian crime, and where people in jail are regularly murdered, spilling the beans is not recommended. But one more key suspect was emerging:  a mysterious character known as ‘El Viejo’.

His capture came at the end of October after months of police work. Clues emerged from messages from El Viejo on Gabriela’s phone. She also confessed to transporting guns and explosives for him on various occasions in Bogotá.

Soon police had a name, Simeón Pérez Marroquín, and a place, in a remote fortified farmstead on the vast plains of Meta. A helicopter team swooped in and took him back to Bogotá.

So where did El Viejo lead?

El Viejo, the ninth capture in the Uribe case, was the most significant. While Chipi coordinated the killing on the ground, it seems El Viejo was closer to the backers.

Another key detail suggests the plot was months in the making: El Viejo was stalking Uribe in March, three months before the shooting in Modelia, and making notes on the senators movements and bodyguards.

Moreover, El Viejo, while living partly in Usme in the south of Bogotá, and on the farm in Meta, also had links to an area of Caquetá known as a stronghold of Segunda Marquetalia.

Segunda Marquetalia? Sounds more like a Cuban singer…

In fact, a recycled FARC guerrilla group named after the original rebel hideout in Tolima. Its leaders were senior commanders who abandoned the peace process in 2019 after persecution by the right-wing Duque government and threats to extradite them to the U.S.

State prosecutors accused some of drug trafficking, charges the commanders claimed were invented. According to Insight Crime, the group lead by Iván Márquez – formerly number two in the FARC – reactivated rebel units in both Colombia and Venezuela, where the group had hidden camps.

But in 2021 Colombian special forces pursued the leaders in Venezuelan territory killing three of the top commander. Further fighting in 2022 wounded Márquez, in fact he was declared dead by Colombian authorities before reappearing in a video in 2024, though he is rumoured to have suffered severe injuries.

A reason to get angry?

Perhaps. A plausible theory is that the Segunda Marquetalia was seeking revenge and targeted Miguel Uribe as a visible – and vulnerable – figure of the Colombian right wing.

Colombian prosecutors claim to have found a digital trail linking El Viejo with the “criminal circle” of Iván Márquez’s armed group. And his stalking of Uribe months before the shooting suggests a long-term plot.

And if such a plot existed, it coincided with the breakdown of peace talks between Petro’s government and the Segunda Marquetalia at the start of 2025, perhaps another spur to action.

But this evidence is yet to be tested in court.  El Viejo is jailed while awaiting trial for aggravated homicide, even while prosecutors are offering him a legal deal for information leading to the ultimate masterminds.

So will El Viejo talk?

That’s what investigators are hoping for. Two of the gang so far sentenced, Gabriela and El Veneco, have collaborated for reduced sentences, both getting 20 years in jail.

With presidential elections in May, and candidates on the stump, Colombia needs clarity.
