Trump says US killed Tren de Aragua boss Niño Guerrero: What is this feared Venezuelan gang?

On Friday, United States President Donald Trump announced that Tren de Aragua leader Héctor Rusthenford Guerrero Flores, better known across Latin America as "Niño Guerrero," had been killed in a military operation carried out in cooperation with Venezuelan authorities.

For years, the Venezuelan criminal organisation has been regarded as one of the fastest-growing transnational gangs in the Western Hemisphere.

The gang has been linked to crimes ranging from human trafficking and extortion to kidnapping, money laundering, contract killings and migrant exploitation.

Its influence expanded alongside the mass migration of Venezuelans fleeing economic collapse, allowing the organisation to establish operations well beyond its home country.

Posting on Truth Social, the US president declared, "At my direction, the United States Southern Command delivered a swift and lethal kinetic strike to successfully execute Nino Guerrero the infamous leader of Tren De Aragua, one of the most bloodthirsty Terrorist Organisations on Planet."

Trump revealed that the operation involved coordination with Venezuelan authorities. "This action was coordinated closely with our friends in Venezuela, with whom we are working very well."

The Pentagon later confirmed details of the mission. US Defense Secretary Pete Hegseth stated on X that the operation had taken place earlier in the week and that Guerrero had been killed during the strike.

According to US officials, the operation targeted a Tren de Aragua compound located in Venezuela. Trump also released unclassified aerial footage showing a small structure with a green roof being destroyed in an explosion.

Venezuela's government also confirmed its participation in the operation and disclosed that it had occurred in Bolívar state, a vast southeastern region rich in mineral resources and bordering both Brazil and Guyana.

A statement issued by Venezuela's information ministry said clashes took place with members of criminal organisations during the operation.

“During the operation, clashes occurred with members of criminal groups, resulting in the death of Héctor Rusthenford Guerrero Flores, alias ‘Niño Guerrero,’ the leader of one of these criminal organisations,” according to the statement.

The ministry stated that specialised technological assistance had been employed during the operation and that the mission relied on cooperation and intelligence-sharing between authorities from both countries.

Hegseth added, “The operation underscores the shared US and Venezuelan commitment to take the fight to narco-terrorists and deny them any safe haven in our hemisphere.”

The strike represented the culmination of years of efforts by US authorities to locate Guerrero. The State Department had previously offered rewards of up to $5 million for information leading to his arrest.

Who was Niño Guerrero?

Before becoming the head of a transnational criminal network, Héctor Rusthenford Guerrero Flores was an inmate inside Venezuela's prison system.

Authorities say Guerrero played a main role in transforming Tren de Aragua from a localised criminal group into a multinational organisation. His rise coincided with a period of political and economic turmoil in Venezuela that reshaped the country's criminal landscape.

Guerrero returned to prison in 2013 after being convicted of murder and other crimes. At the same time, Venezuela was entering a prolonged economic crisis triggered by corruption, mismanagement and declining oil prices, factors that severely weakened state institutions.

According to reports, Guerrero and several associates exploited deteriorating conditions within Venezuela's prisons to build power. Rather than remaining ordinary inmates, they gradually established control over prison operations and developed a system that governed prisoners through intimidation, violence and extortion.

Over time, Guerrero became the dominant figure within Tocorón Prison, the facility that would later become synonymous with Tren de Aragua.

From there, authorities allege he directed an increasingly sophisticated criminal enterprise while serving a prison sentence.

His influence eventually became so extensive that US prosecutors charged him in a federal court in New York with racketeering conspiracy and other offences, including allegations related to providing support to terrorists. Authorities announced those charges in December.

His criminal activities also attracted sanctions from the Trump administration, which repeatedly targeted Guerrero and other senior figures within the organisation over allegations involving drug smuggling, human trafficking and money laundering.

The pursuit of Guerrero escalated after US authorities designated Tren de Aragua as a foreign terrorist organisation and began treating the gang as a major security threat.

How did Tren de Aragua emerge from a railway project in Venezuela?

The origins of the organisation differ significantly from those of traditional drug cartels. According to reports, the group first emerged during the late 2000s around an unfinished railway project in Venezuela's Aragua state. The term "Tren" itself is linked to that railway development.

Initially, the organisation functioned as a violent labour group connected to construction activity surrounding the project. Members became involved in extortion schemes, bribery and other criminal practices associated with employment and contracting opportunities.

As authorities arrested members of the group, many ended up in Tocorón Prison, officially known as the Aragua Penitentiary Center. Instead of weakening the organisation, incarceration helped consolidate its leadership.

Between 2010 and 2013, Guerrero steadily expanded his authority inside the prison. During this period, Tren de Aragua evolved from a regional gang into a structured criminal organisation capable of coordinating activities across multiple territories.

The group's transformation accelerated after 2018.

While still imprisoned, Guerrero allegedly used the growing Venezuelan migration crisis to extend the gang's reach beyond national borders.

As millions of Venezuelans left the country, Tren de Aragua reportedly followed migration routes and established cells in strategic locations, particularly near border crossings between Venezuela and Colombia. This expansion laid the groundwork for the organisation's later growth across South America.

What made Tocorón Prison the nerve centre of the gang?

For years, the facility served not merely as a detention centre but effectively as the headquarters of the organisation.

The prison operated under what is often referred to as Venezuela's "pranato" system. Under this arrangement, prison bosses known as "pranes" exercised extensive authority within correctional facilities.

Authorities and investigators say Guerrero used this system to create a highly secure operational base from which he managed criminal activities both inside and outside Venezuela.

Reports indicate that Guerrero controlled an entire floor of the prison and was protected by bodyguards. The prison itself became notorious because of the amenities available inside its walls.

According to reports, the facility contained:

Some accounts described the prison as functioning almost like a self-contained town rather than a correctional institution.

The arrangement provided several advantages to the gang. It enabled leadership to avoid direct confrontation with law enforcement, accumulate financial resources, recruit new members from among inmates and coordinate criminal activities with limited outside interference.

The system continued until September 2023, when Venezuelan authorities launched a massive operation to retake control of Tocorón.

More than 11,000 security personnel participated in the raid. However, Guerrero and numerous senior gang members escaped before authorities arrived. Reports later suggested that gang leaders used an extensive tunnel system stretching approximately five kilometres.

The prison raid became one of the most significant anti-gang operations in Venezuela's modern history.

How did the gang spread across Latin America and beyond?

Rather than focusing exclusively on narcotics trafficking, the group built a diversified criminal portfolio and leveraged migration flows throughout the region. The mass departure of Venezuelans created opportunities for the organisation to establish footholds in multiple countries.

Authorities say gang operatives positioned themselves along migration corridors and gradually embedded criminal networks in destination countries receiving large numbers of Venezuelan migrants.

Countries including Colombia, Peru and Chile have repeatedly accused Tren de Aragua of involvement in violent crime and organised criminal activity.

The gang also expanded into other parts of South America and eventually established a presence in Europe and the United States. One of its most important strategic assets was control over illicit border crossings known as trochas along the Colombia-Venezuela frontier.

Control of these routes enabled the organisation to profit from migration while expanding recruitment and trafficking networks. According to law-enforcement officials across the region, the gang's influence eventually stretched from Panama to Brazil and throughout the Andean corridor.

What criminal activities has Tren de Aragua been accused of?

Human trafficking remains among the accusations most frequently levelled against the group. Investigators say the organisation exploited vulnerable migrants and established systems that profited from illegal border crossings.

The group has also been accused of luring women and girls with promises of employment opportunities abroad before trapping them through debt arrangements and forcing them into sexual exploitation.

Beyond trafficking activities, authorities have connected the organisation to:

One notable aspect of the gang's structure is its so-called franchise model.

According to reports, local criminal groups in countries such as Colombia, Peru and Chile could operate under the Tren de Aragua banner by paying recurring fees known as "causa."

The arrangement allowed the organisation to expand without maintaining direct control over every criminal cell. Authorities say smaller gangs were often absorbed into the network, while groups that resisted integration could face violent retaliation.

In addition, investigators have linked the organisation to "gota a gota" lending operations, a form of predatory loan-sharking targeting people who lack access to conventional banking systems.

Although the gang has been connected to narcotics trafficking, experts note that it differs from traditional cocaine-focused cartels.

According to InSight Crime, the organisation has not developed the same large-scale international cocaine trafficking infrastructure associated with some criminal groups from Colombia, Central America or Brazil.

Why did Tren de Aragua become a concern for the United States?

US authorities allege that Tren de Aragua established criminal footprints in several metropolitan areas, including New York City, Chicago and Aurora, Colorado. Investigators have accused gang members of involvement in retail theft operations, armed robberies, forced prostitution and other criminal enterprises.

According to reports, some operatives allegedly used municipal migrant shelters as locations for recruitment and criminal coordination. The organisation's growing presence prompted increasingly aggressive responses from the Trump administration.

The administration has also pursued sanctions against key leaders and adopted broader legal tools to target the group.

Authorities placed multimillion-dollar rewards on Guerrero and other senior figures while invoking wartime-style frameworks in efforts to combat the organisation's activities.

Trump repeatedly portrayed the gang as a central driver of violence and criminality affecting American communities. His administration also cited alleged connections between Tren de Aragua and the government of Venezuelan President Nicolás Maduro.

Trump has claimed that the gang coordinated its activities inside the United States with the Venezuelan government. The administration used those allegations to justify a variety of measures, including deportations of certain migrants to a maximum-security prison in El Salvador.

The US president also pursued military operations targeting vessels accused of involvement in narcotics trafficking. According to reports, more than 200 people have been killed in boat strikes carried out by US forces since the administration began targeting what it describes as "narcoterrorists."

Following Guerrero's death, Trump delivered a warning to remaining members of the organisation.

“Tren de Aragua terrorists no longer have safe haven in Venezuela or anywhere else and, under my leadership, we will find these vicious murderers and drug lords anytime, anyplace, and send them to the depths of hell where they belong.”

The death of Niño Guerrero removes the figure most closely associated with the rise of Tren de Aragua.
