Two alleged leaders of the Venezuelan criminal group Tren de Aragua have been indicted by a federal grand jury in Colorado on multiple charges, including conspiracy under the Racketeer Influenced and Corrupt Organization (RICO) Act. 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” or “El Viejo,” are accused of participating in organized criminal activity in Colorado from May 2024 through March 2025.
The indictment alleges that Suarez Villegas and Mosquera Serrano engaged in racketeering activities such as robbery, extortion, kidnapping, money laundering, and offenses involving controlled substances. Both men are also charged with conspiracy to commit robbery and two counts of Hobbs Act Robbery and firearms violations related to armed robberies at two jewelry stores in Denver during June 2024.
Additional individuals face federal charges connected to one of these robberies. Newman Castillo-Delgado was sentenced to 240 months in prison on December 17, 2025, after pleading guilty to charges including Hobbs Act Robbery and brandishing a firearm during a violent crime related to the robbery of Joyeria El Ruby in June 2024. During this incident, nearly $4 million worth of jewelry and gold were stolen and several employees were beaten with firearms.
Suarez Villegas faces further charges for conspiracy to commit kidnapping, kidnapping, cyberstalking, and a firearms offense tied to an October 2024 incident involving ransom demands, torture, and disfigurement of a victim in Denver. Others are charged federally regarding this case.
The investigation involves collaboration between the FBI Denver Field Office, Denver Police Department, Colombian National Police GAULA ELITE unit, and DEA Bogota Country Office – Group 3.
This year alone the District of Colorado has brought additional indictments against about thirty individuals—including other alleged Tren de Aragua members—on drug trafficking, murder-for-hire plots, and firearms offenses.
Prosecution is being managed by the Violent Crime and Immigration Enforcement Section of the U.S. Attorney’s Office for the District of Colorado along with members from Joint Task Force Vulcan (JTFV). JTFV was established in 2019 initially targeting MS-13 but now also addresses Tren de Aragua activities across several U.S. districts with support from agencies like FBI, DEA, HSI, ATF, USMS; international assistance came from offices based in Bogotá.
This action is part of Operation Take Back America—a Justice Department initiative combining resources from OCDETFs and Project Safe Neighborhoods aimed at combating illegal immigration as well as dismantling cartels and transnational criminal organizations nationwide. In February 2025 the Trump Administration designated Tren de Aragua both as a Foreign Terrorist Organization (FTO) and Specially Designated Global Terrorist (SDGT).
A reward up to $5 million is offered by the State Department’s Transnational Organized Crime Rewards Program for information leading to Mosquera Serrano’s arrest or conviction. Individuals can contact the FBI at +1 281-787-9939 via text or messaging apps if they have relevant information.
“The charges contained in the indictments are merely accusations,” notes the release. “The defendants are presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law.”
