Two individuals alleged to be leaders of the Venezuelan criminal organization Tren de Aragua have been indicted by a federal grand jury in Colorado. The United States Attorney’s Office for the District of Colorado announced that Brawins Dominique Suarez Villegas, also known as “Chino San Vicente,” and Giovanni Vicente Mosquera Serrano, also known as “Jovani San Vicente” and “El Viejo,” face several charges, including conspiracy under the Racketeer Influenced and Corrupt Organizations (RICO) Act.
According to the indictment, from May 2024 through March 2025, Suarez Villegas and Mosquera Serrano engaged in racketeering activity on behalf of Tren de Aragua. The alleged crimes include robbery, extortion, kidnapping, money laundering, and offenses related to controlled substances. Both defendants are additionally charged with conspiracy to commit robbery and two counts of Hobbs Act Robbery and firearms violations connected to armed robberies at two jewelry stores in Denver in June 2024.
Other individuals are also facing federal charges linked to one of these jewelry store robberies. Newman Castillo-Delgado was sentenced on December 17, 2025, to 240 months in prison after pleading guilty to Hobbs Act Robbery and brandishing a firearm during a crime of violence related to his involvement in the June 2024 robbery at Joyeria El Ruby. During this incident, nearly $4 million worth of jewelry and gold was stolen and multiple employees were assaulted with firearms.
Suarez Villegas faces further charges including conspiracy to commit kidnapping, kidnapping, cyberstalking, and a firearms offense arising from an October 2024 case involving kidnapping, ransom demands, torture, and disfigurement of a victim in Denver. Other suspects have been charged federally for this crime as well.
The investigation involves cooperation between the FBI Denver Field Office and the Denver Police Department with support from Colombian law enforcement agencies.
In addition to these cases, earlier indictments this year charged thirty people—among them other Tren de Aragua leaders—with crimes such as drug trafficking and murder-for-hire schemes across multiple case numbers.
Prosecution is led by the Violent Crime and Immigration Enforcement Section of the U.S. Attorney’s Office for Colorado alongside members of Joint Task Force Vulcan (JTFV). JTFV began in 2019 targeting MS-13 but now also pursues Tren de Aragua activities nationally with contributions from various U.S. Attorney’s Offices across several states as well as federal agencies like FBI, DEA, HSI, ATF, USMS; international assistance has come from both Justice Department offices abroad.
This prosecution is part of Operation Take Back America—a national initiative intended to combat illegal immigration-related crime networks by pooling resources from law enforcement programs such as OCDETFs (Organized Crime Drug Enforcement Task Forces) [More information about OCDETFs](https://www.justice.gov/ocdetf/about-ocdetf) —and Project Safe Neighborhood (PSN) [Details on PSN](https://www.justice.gov/psn/project-safe-neighborhoods).
On February 20th 2025 under the Trump Administration Tren de Aragua was designated both a Foreign Terrorist Organization (FTO) [State Department FTO List](https://www.state.gov/foreign-terrorist-organizations/) —and Specially Designated Global Terrorist (SDGT).
A reward up to $5 million is being offered by the State Department’s Transnational Organized Crime Rewards Program for information leading directly to Mosquera Serrano’s arrest or conviction; tips can be submitted via phone or encrypted messaging apps through contacts provided by authorities.
“The charges contained in the indictments are merely accusations,” notes officials. “The defendants are presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law.”
