Two alleged leaders of the Venezuelan gang Tren de Aragua have been indicted by a federal grand jury in Colorado on charges that include 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,” face allegations of participating in a pattern of racketeering activity from May 2024 through March 2025.
According to the indictment, Suarez Villegas and Mosquera Serrano are accused of conducting activities for Tren de Aragua involving robbery, extortion, kidnapping, money laundering, and controlled substance offenses. They are also charged with conspiracy to commit robbery and two counts of Hobbs Act Robbery, along with firearms offenses related to armed robberies at two jewelry stores in Denver in June 2024.
Other individuals have been charged federally in connection with one of these robberies. Newman Castillo-Delgado was sentenced to 240 months in prison on December 17, 2025, after pleading guilty to Hobbs Act Robbery and brandishing a firearm during a crime of violence tied to the Joyeria El Ruby robbery in June 2024. During this incident, nearly $4 million worth of jewelry and gold was stolen and several employees were beaten with a firearm.
Suarez Villegas faces additional charges including conspiracy to commit kidnapping, kidnapping, cyberstalking, and a firearms offense related to an October 2024 incident involving ransom demands, torture, and disfigurement of a victim in Denver. Other defendants are facing federal charges connected to this case.
The investigation is being led by the FBI Denver Field Office and the Denver Police Department. Support has come from Colombian National Police GAULA ELITE unit and DEA Bogota Country Office - Group 3.
Earlier this year, the District of Colorado announced two other federal indictments charging thirty people—including other alleged Tren de Aragua leaders—with drug trafficking, murder-for-hire plots, and firearms violations.
Prosecutions are being managed 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 was formed in 2019 initially targeting MS-13 but now includes efforts against Tren de Aragua across multiple U.S. Attorney’s Offices nationwide. The task force includes agencies such as the FBI, DEA, HSI, ATF, USMS, Federal Bureau of Prisons as well as support from international offices like those based in Bogotá.
This case falls under Operation Take Back America—a Justice Department initiative aimed at combating illegal immigration and dismantling transnational criminal organizations using resources from Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN). In February 2025, the Trump Administration designated Tren de Aragua as both a Foreign Terrorist Organization (FTO) and Specially Designated Global Terrorist (SDGT).
The State Department is offering up to $5 million for information leading to Mosquera Serrano’s arrest or conviction. Anyone with information is encouraged to contact the FBI at +1 281-787-9939 via text or messaging apps.
“The charges contained in the indictments are merely accusations, and the defendants are presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law.”
Case Number: 1:25-cr-00331-PAB
