The Office of Foreign Assets Control (OFAC) from the U.S. Department of the Treasury announced on Thursday that it has imposed sanctions on Hector Rusthenford Guerrero Flores, also known as “Niño Guerrero”. Guerrero, along with five other prominent leaders and members of the Tren de Aragua group, have been targeted by these sanctions.

This group, Tren de Aragua, which was identified by the State Department on February 20 as a foreign terrorist organization, originated in Venezuela and consists of thousands of members.

Hector Guerrero, aged 42, is acknowledged for expanding Tren de Aragua from a prison-based gang focused on extortion and bribery into a significant organization that poses a threat to public safety throughout the Western Hemisphere.

In addition to the sanctions, the Treasury Department is offering a reward of up to $5 million for information leading to Guerrero’s arrest and conviction.

The sanctions block the property of designated individuals in the U.S., prohibiting anyone in the U.S. from doing business with them—unless authorized. 

Violations can result in penalties, and financial institutions risk sanctions for dealing with those who are blocked. Foreign banks may face secondary sanctions.

Other suspected Tren de Aragua leaders sanctioned by the Treasury Department on Thursday include:

Yohan Jose Romero, aka “Johan Petrica”

Yohan Jose Romero, reportedly one of Guerrero’s co-founders and a close lieutenant, is allegedly responsible for the group’s illegal mining efforts in Venezuela. 

The 47-year-old is also accused of providing Tren de Aragua with military-grade weapons used to control the streets of Venezuela and fight against Colombian guerrillas. The State Department is offering a $4 million reward for his arrest and conviction.

Josue Angel Santana Pena, aka “Santanita”

Josue Angel Santana Pena, 30, reportedly served time with Guerrero in Tocoron Prison and helped direct Tren de Aragua from within the prison. 

Pena was allegedly involved in homicide, extortion, bombings, terrorism and theft.

Wilmer Jose Perez Castillo, aka “Wilmer Guayabal”

Wilmer Jose Perez Castillo, 39, is allegedly one of Guerrero’s lieutenants and the leader of a Tren de Aragua cell involved in drug trafficking and bribe collection in Venezuela. 

Castillo is accused of executing the murders of a police officer, Venezuelan military official and Venezuelan intelligence officials on behalf of Tren de Aragua. 

Wendy Marbelys Rios Gomez

Guerrero’s wife, Wendy Marbelys Rios Gomez, 45, is reportedly linked to criminal activities including money laundering, terrorism and terrorist financing.

Felix Anner Castillo Rondon, aka “Pure Arnel”

Felix Anner Castillo Rondon is believed to be the leader of a Tren de Aragua cell known as “Los Gallegos,” which operates in Chile. 

Los Gallegos is reportedly implicated in homicides, human trafficking, sexual exploitation of women, narcotics trafficking, and money laundering.
