Bolivia Holds Colombian, Seizes US$500,000

BOLIVIA · SECURITY

Bolivian police presented a Colombian suspect on Thursday with over US$500,000, four gold bars and weapons found at his home. Authorities are testing whether he belonged to a network tied to Sebastián Marset, a link they call a hypothesis.

Bolivia holds Colombian Carlos Vargas Ramírez after police found over US$500,000, gold bars and weapons at his Santa Cruz home. Bolivia’s prosecutors say police suspect he may belong to a network tied to Sebastián Marset, now awaiting trial in the United States.

Police arrested him on Wednesday, 14 October, after tracking a phone of the victim, Johan Guzmán Parada, 26. The Fiscalía, Bolivia’s prosecutor’s office, lists murder among the offences under investigation, though police say his role is not yet established.

What Police Say They Found

Police commander Adrián Álvarez presented the suspect on Thursday, 15 October, alongside Government Minister Marco Antonio Oviedo, who oversees the police. The commander said officers identified his home in the La Molina area of northern Santa Cruz, El Deber reported.

Police listed more than US$500,000 in cash dollars and over Bs 130,000 (about US$11,100), El Deber and El Día said. El Deber put the dollars at US$546,500, and El Día’s subheading gives the same figure.

Bolivian amounts here convert at the central bank’s official rate of Bs 11.68 per US$ on 15 October 2026. Bolivia dropped its fixed rate this year, which Bolivia in 2026 Explained covers, so Bs 130,000 is about US$11,100.

Four small gold bars and jewellery were also found, El Deber, El Día and Infobae said. Visión 360 also mentioned small gold bars, and none of the accounts gives a weight or value.

Police described five pistols, a precision rifle and 550 rounds, El Deber and Infobae said. The Fiscalía listed six revolvers, a rifle and about 500 rounds on Wednesday, and the two counts differ.

Why Bolivia Holds Colombian Suspect Carlos Vargas Ramírez

The Fiscalía, led by interim Attorney General José Armando Urioste, names four offences under investigation: murder, arms trafficking, weapons possession and laundering. Los Tiempos said prosecutors pursue him for arms trafficking, weapons possession and laundering; his role in the killing is unproven.

El Deber quoted Álvarez as saying the case is still being investigated to establish the suspect’s participation. El Diario says investigators are asking whether he planned the attack, as does JuanPastén.bo, citing Sierra Televisión; this is unproven.

The Killing of Johan Guzmán and the Marset Hypothesis

Johan Guzmán Parada, 26, was shot dead on Tuesday, 13 October, at a mechanic’s workshop near the city’s zoo. The Fiscalía describes a contract killing: two men arrived on a motorcycle and one entered the workshop armed and fired.

The Fiscalía says police are testing whether the suspect belonged to a criminal group tied to Marset and alias El Colla. It says the victim allegedly had ties to the same structures, and it calls both points hypotheses still to be verified.

In 2023 the government of the day described Guzmán as a pilot for Marset, El Deber recalled. Lawyer Ángel Veizaga said on Wednesday that no link between Guzmán and Marset has been proved, El Deber reported.

Who Sebastián Marset Is and His US Case

Sebastián Marset, a Uruguayan drug-trafficking suspect, was captured in Bolivia on 13 March and now faces charges in the United States. The OCCRP, an investigative reporting network, says a Virginia federal judge set his trial for 11 January 2027.

Charges there began with money laundering, and a later indictment added drug trafficking and narcoterrorism, the OCCRP said. His defence has signalled it will challenge the handover, which Marset calls an irregular rendition.

El Colla is Erlan Ivar García López, whom a former minister called a trusted man of Marset in 2023, El Deber recalled. The Fiscalía’s statement does not say whether García López faces charges or has any link to this arrest.

What It Means for US Readers

The US State Department rates Bolivia Level 2, exercise increased caution, in an advisory issued on 18 August 2026. It says express kidnappings, in which victims are forced to withdraw cash at ATMs, are uncommon and mostly occur in Santa Cruz.

Marset awaits trial in a US federal court, so any proven link to him would reach into an American case. For now it is a hypothesis from Bolivian police and prosecutors, and the official statements mention no US role in this arrest.

What Is Not Known

The accounts differ on some details: Vargas Ramírez is 42 in the Fiscalía’s account and 38 in police remarks. Weapon and ammunition counts also differ between Wednesday’s and Thursday’s lists.

The exact dollar total is unsettled: El Deber says US$546,500, while El Día’s text says about US$540,000. No weight or value has been given for the four gold bars.

Whether Vargas Ramírez fired the shots or planned the killing has not been established. Police say they are still checking whether the seized money, gold and weapons relate to the killing.

No statement from Vargas Ramírez or a lawyer for him has appeared in the coverage. The Marset link remains a hypothesis that the Fiscalía says must still be verified.

What Comes Next

El Diario said prosecutor Yolanda Aguilera will seek more checks at the workshop and summon the victim’s mother. El Deber said prosecutor Gary Flores will request pretrial detention, but no hearing date or detention order has been announced.
