The story of the prison gang that became South America's most feared criminal brand—now spreading into the United States.

This authoritative guide is the first comprehensive book to chronicle the rise, reach, and transformation of Tren de Aragua, a Venezuelan gang born inside the infamous Tocorón prison and now operating across Latin America and beyond. From the moment it seized control of its own prison-turned-palace—complete with nightclubs, swimming pools, and a zoo—Tren de Aragua built a criminal empire like no other.

Through brutal extortion, sex trafficking, and control of migrant routes, the Tren de Aragua gang has embedded itself in communities across Colombia, Chile, Peru, and is now being tracked as far afield as the U.S. And as headlines buzz about Tren de Aragua tattoos, kidnappings, and arrests, this book offers the most detailed breakdown of the gang out there.

Structured in thematic chapters for easy access, Tren de Aragua - The Guide to America's Growing Criminal Threat reveals:

• How Tren de Aragua was incubated inside Tocorón and how it turned Venezuela’s state failure into criminal opportunity

• The gang’s sophisticated network of sex trafficking, extortion, migrant smuggling, illegal gold mining, and ketamine trafficking

• How Tocorón became the gang’s operational fortress and surreal symbol of state complicity, before its fall in 2023

• The criminal “franchise” system that allowed El Tren de Aragua to scale across borders—exporting its name, not just its people

• How to distinguish between the core gang, its franchise cells, and the copycats who use the name to terrify communities without any real ties

• How its unique criminal model functions: an opportunistic expansion strategy that feeds on mass migration, state neglect, and transnational flows

• A state-by-state breakdown of reported Tren de Aragua activity in the United States—what’s real, what’s media panic, and where the evidence is still lacking

• How governments in Colombia, Chile, the U.S. and even Venezuela differ radically in their assessment of the gang—and what that means for policy

But this book doesn’t just tell the story of a gang—it shows how Tren de Aragua reflects a larger trend: what happens when gangs replace government.

In Venezuela, where the state retreated, Tren de Aragua stepped in—governing prison cities, taxing local economies, and co-opting mass migration to fuel its growth. Where many cartels fight for territory, Tren de Aragua thrives on movement, seizing opportunity across borders and hiding in the slipstreams of humanitarian crises.

You’ll meet Niño Guerrero, the gang’s elusive leader whose iron-fisted rule turned a prison into a kingdom. You’ll follow Johan Petrica, the strategist behind the gang’s entry into illegal gold mining and smuggling. And you’ll uncover how the Venezuelan regime helped nurture the gang's rise—whether through negligence, corruption, or deliberate symbiosis.

Drawing on hundreds of sources—from law enforcement reports and frontline journalism to exclusive interviews—this is not a speculative account. It’s a briefing for those who want to understand the real dynamics of one of today’s fastest-spreading criminal threats.
