Vladimir Antonio Arévalo-Chávez

Vladimir Antonio Arévalo-Chávez, known as “Vampiro de Monserrat Criminales,” is one of the senior MS-13 figures charged in the federal case commonly described as the Ranfla II prosecution. U.S. prosecutors have portrayed him as a leader whose importance went well beyond a single clique. The indictment alleges that he served as the leader of the San Salvador Program, participated in negotiations with representatives of the government of El Salvador on behalf of MS-13, later fled to Mexico, and became a leader of the gang’s Mexico Program.

His nickname links him to Monserrat Criminales, a clique identity that should be preserved as its own canonical node rather than buried in a biography. That relationship matters because the archive is building MS-13 as a hierarchy of verifiable connections: individual people at one level, clicas and programs at another, and senior command structures above them. Arévalo-Chávez sits at the point where several of those levels overlap.

The federal indictment identifies him as a member of MS-13 and alleges that he led the San Salvador Program. Programs in MS-13 records are broader operational structures than a single local clique, and the San Salvador Program therefore deserves a separate page linked back to its confirmed leaders and subordinate or associated clicas as those are documented. The same indictment alleges that Arévalo-Chávez took part in negotiations between MS-13 and officials of the Salvadoran government. Those negotiations belong to a larger event cluster and should eventually connect to dedicated the archive pages covering truces, political negotiations and state responses to gang power.

According to the indictment, Arévalo-Chávez later fled El Salvador for Mexico to avoid law enforcement and became a leader of the Mexico Program. That makes him a particularly important bridge between the El Salvador cluster and the Mexican organized-crime network already being developed elsewhere on the archive. The Mexico Program is alleged to have helped MS-13 expand operations, obtain weapons and narcotics connections, facilitate smuggling and coordinate members across borders. A profile such as Arévalo-Chávez’s therefore cannot be understood only through one country.

His status also illustrates the international enforcement effort against MS-13 leadership. On February 22, 2023, Mexican authorities located Arévalo-Chávez together with Walter Yovani Hernández-Rivera and Marlon Antonio Menjívar-Portillo. U.S. prosecutors stated that the three were expelled from Mexico via the United States and taken into U.S. custody. Their indictment was unsealed the following day in the Eastern District of New York. The case charged thirteen alleged senior leaders with racketeering conspiracy, terrorism-related conspiracy and narco-terrorism conspiracy, while four defendants also faced an alien-smuggling conspiracy count.

the archive must preserve the legal distinction between allegation and adjudicated fact. The Ranfla II indictment describes the government’s case against Arévalo-Chávez; it does not by itself establish guilt. The public profile should therefore use formulations such as “prosecutors allege” when describing the conduct charged in that case, while treating the arrest, aliases, indictment, custody transfer and publicly documented organizational relationships as procedural or historical facts.

Within the knowledge graph, Arévalo-Chávez should link bidirectionally to MS-13, Monserrat Criminales, the San Salvador Program, the Mexico Program and the Ranfla II federal case. He should also connect to the February 2023 Mexico arrests event and to the other defendants arrested alongside him. As the El Salvador cluster expands, his profile can support additional verified links to gang-government negotiations and Mexico-based operations.

That combination of clique identity, program leadership, international movement and senior prosecution makes Arévalo-Chávez one of the strongest anchor nodes in the second layer of the MS-13 graph.
