The death of Waldemar Antonio Barrios Castillo, known as “Niño Guerrero,” a leading figure in the Venezuelan criminal organization Tren de Aragua, has prompted changes to the FBI’s Ten Most Wanted Fugitives list. Giovanni Mosquera Serrano, another member of Tren de Aragua, remains on the list and is actively sought by authorities. Tren de Aragua is a transnational criminal group responsible for various crimes, including extortion, kidnapping, and murder, with a significant presence in Venezuela, Colombia, and the United States. The FBI continues to seek information leading to the arrest of Mosquera Serrano and other key members of the organization. “Niño Guerrero’s” death signifies a disruption to the gang’s leadership, but the organization remains a threat. The updated list reflects the FBI’s ongoing efforts to dismantle Tren de Aragua and bring its members to justice. Authorities are concerned about the group’s expanding influence and its potential to commit further crimes.
