In late June 2025, the arrest of Celso Gamboa Sanchez, a former Costa Rican Supreme Court justice, ex-national security minister, and former prosecutor, sent shockwaves through the nation’s political and legal establishments. Accused of ties to drug trafficking, Gamboa was detained and faced the once-unthinkable prospect of extradition to the United States. While the news made international headlines, the true catalyst for this high-stakes takedown wasn’t a sprawling, multi-year investigation by a federal agency. It was the culmination of a relentless, clandestine campaign waged by an anonymous whistleblower, ignited by a single, strategically delivered complaint to the U.S. State Department.
This is the story of how one person’s determination to expose a web of corruption victimizing an American investor set in motion a chain of events that brought the full weight of the U.S. government to bear on Costa Rica. It’s a narrative of frustration, persistence, and a high-stakes gambit that finally paid off, leading to a dramatic shift in the fight against transnational crime and official complicity in the Central American nation.
The Victim and The Conspiracy: An American’s Nightmare in Paradise
The saga begins not with secret government communiqués, but with the plight of Enzo Vincenzi, an American investor who found himself ensnared in what he has described as a sophisticated conspiracy. For years, Vincenzi’s story has been one of systematic persecution, financial ruin, and institutional betrayal, a cautionary tale for any foreigner looking to do business in a country whose idyllic image masks a darker reality.
According to extensive documentation, Vincenzi’s ordeal involved a complex web of alleged corruption implicating public attorneys, officials, and private citizens. His case, detailed in a series of exposés, paints a picture of a justice system weaponized against him. He faced fraudulent lawsuits, property theft, and threats, all while his attempts to seek redress through Costa Rican legal channels were allegedly stymied by corrupt actors. As one report and video from The AEGIS Alliance titled “The Costa Rica Conspiracy” outlines, the efforts against Vincenzi were designed to financially and psychologically break him, but he stood strong, and decided to face the injustices committed against him.
The frustration was palpable. Vincenzi even took the extraordinary step of offering a $5,000 each reward for information leading to the arrest and conviction of the corrupt officials he believed were responsible for his persecution. This was not the action of a man who had faith in the system; it was a measure meant to convey a powerful message, born from years of unanswered pleas for justice.
Watching this unfold was an individual who would become the whistleblower. This person methodically documented the injustices against Vincenzi, compiling evidence and crafting legal arguments. The whistleblower’s involvement went back to at least 2022, and in September 2024, the cloaked heroic figure had authored a detailed, 14-page criminal complaint dossier, complete with extensive photographic and video evidence, that exposed the corruption nexus at the heart of Vincenzi’s case. The dossier for the public to view is 13 pages, while the version intented only for President Rodrigo Chaves and the Costa Rica Immigration Department is 14 pages.

For over three years, the whistleblower wrote numerous criminal complaints for Vincenzi to file in Costa Rican courts, but they languished, seemingly ignored by the very institutions meant to investigate them.
The sentiment of a lone individual fighting a seemingly insurmountable system was perfectly captured by a commenter on a YouTube video discussing U.S. extradition requests from Costa Rica: “What is incredible is that a civilian without a salary or institutional support has brought to light the negligence or possible complicity of so many people involved in drug distribution, both in the private and public sectors.” – @antoniojimenez7106
This comment seemed to reflect American investor Enzo Vincenzi’s plight, however, it encapsulates the essence of the whistleblower’s long and often lonely battle, although, Vincenzi and the whistleblower were exposing corrupt public officials and attorneys, not drug traffickers specifically. With the Costa Rican system appearing impenetrable, a new strategy was needed. The fight had to be escalated to a higher power—the United States government.
The Gambit: A Two-Pronged Appeal to Washington
The whistleblower’s strategy shifted from seeking justice within Costa Rica to demanding intervention from the outside. This involved a two-stage approach, leveraging the U.S. government’s obligation to protect its citizens abroad.
Stage One: The Embassy Complaint and Building Interest
The first major move came in September 2024. Vincenzi, seeking help, visited the U.S. Embassy in San José, Costa Rica. His experience there, however, was allegedly one of neglect and dismissal, leaving him feeling abandoned by his own country. According to a formal complaint later written by the whistleblower, Vincenzi’s human rights were violated during this encounter, as embassy staff reportedly failed to provide the assistance and protection he was entitled to as an American citizen in peril.
This incident became the basis of a formal complaint sent to the U.S. State Department. But the whistleblower was playing a longer game. The complaint wasn’t just sent to the incumbent administration; copies were also directed to key figures in the presidential campaign of former and current U.S. presdent as of 2025, Donald J. Trump. This was a strategic hedge, ensuring that no matter the outcome of the 2024 election, the information would be in the hands of people with influence. While this letter didn’t trigger an immediate, overt response, it successfully placed Vincenzi’s case—and the broader issue of Costa Rican corruption affecting Americans—on the radar of incoming U.S. officials. It laid the groundwork and built crucial interest.
Stage Two: The “Ignite Letter” and a Secretary’s Sudden Detour
With a new administration in place in 2025, the whistleblower saw a new opportunity. In early January 2025, a second, more pointed formal complaint was written and completed, then dispatched to the State Department, now under the leadership of Secretary of State Marco Rubio. This, the whistleblower later clarified, was the “ignite letter”—the one that tipped the scales. Also at around the same time, Mr. Vincenzi was brutally assaulted by an alleged attacker, corrupt public attorney Yorleni Diaz’s son. (ZIP File Download HERE.)
The effect was almost immediate and highly visible. Secretary Rubio had a planned diplomatic trip to Central America, with scheduled stops that included Panama and El Salvador. Suddenly, his itinerary changed. An additional stop was added: San José, Costa Rica. For close observers, this unscheduled detour was a clear signal. A complaint from an anonymous source about the plight of a single American investor had seemingly been elevated to a matter of U.S. national interest, compelling a visit from one of the nation’s top diplomats.

The Dominoes Fall: The U.S. Response Unleashed
Secretary Rubio’s visit in early February 2025 was not merely a diplomatic courtesy. It was the harbinger of an unprecedented U.S. crackdown. In the months that followed, the promises of intervention became a reality as a formidable contingent of U.S. agencies descended upon Costa Rica. The Department of Homeland Security (DHS), the Drug Enforcement Administration (DEA), the Federal Bureau of Investigation (FBI), and even elements of the U.S. military arrived to carry out official duties. The message was unmistakable: the United States was no longer willing to tolerate a system where its citizens could be victimized and where transnational criminal organizations could operate with impunity, allegedly enabled by corrupt local officials.
The pressure mounted. The presence of U.S. law enforcement and intelligence agencies created a new political reality in Costa Rica. This pressure was instrumental in a landmark legislative change. In early June 2025, Costa Rica’s legislature passed a new law reforming Article 67 of the Law on Narcotics, Psychotropic Substances, and Related Crimes. As reported by The Tico Times, this reform opened the door for the extradition of Costa Rican nationals for drug trafficking offenses, a practice previously barred by the country’s constitution. While the law has its limitations and doesn’t cover all crimes, it was a seismic shift specifically designed to target the high-level narcotraffickers and their collaborators who had long felt untouchable.
The whistleblower had told Vincenzi just days before the law passed that more crimes continue to be committed against Mr. Vincenci, that there hasn’t been any more movement with the complaints in the courts. Not long after that, Costa Rica passed the law in early June to make criminals able to be extradited to face trial and consequences in other countries, including drug traffickers and corrupt Costa Rican officials who are able to be extradited to the U.S. to face trial. The whistleblower had gone through three years of knowing of the crimes that continued to be committed against Mr. Enzo Vincenzi before action was finally taken and they finally saw light shine through during their mission.
The new law didn’t have to wait long to be tested.
Just weeks later, in late June 2025, authorities arrested Celso Gamboa Sanchez. According to a report from Reuters, Costa Rica’s Judicial Investigation Police (OIJ) confirmed that Gamboa was detained on drug trafficking charges following a U.S. extradition request. The arrest was a stunning development, targeting a figure who had occupied the highest echelons of the country’s justice and security apparatus.
For the whistleblower and Enzo Vincenzi, it was a moment of profound vindication. Just two days before Gamboa’s arrest, the two had been on a phone call, expressing mutual uncertainty about whether their years of effort would ever bear fruit. Vincenzi had high hopes, but after so many setbacks, doubt lingered. Two days later, the news broke. The arrest was tangible proof that their campaign had succeeded. The abstract pressure applied by the complaint letter had materialized into concrete law enforcement action against one of the most powerful figures in the country.
A Glimmer of Justice and a Budding Alliance
The impact continues to reverberate. In the wake of Gamboa’s arrest and the clear signal of U.S. involvement, other wheels of justice began to turn. The Costa Rican witness protection department, which had previously been unresponsive, finally agreed to move forward with Enzo Vincenzi’s case—a decision undoubtedly made under the immense pressure of the new political climate.
The whistleblower’s actions have also fostered new alliances. In a recent Signal conversation with a person conducting extensive undercover investigations in Costa Rica, the gravity and interconnectedness of their work became clear.
“Pressure is what we are gonna get,” the undercover investigator wrote. “I will be invested and share all. Our cases are tied together closely. I’ll trust you if you trust me.”
“Yes, let’s continue to build our trust with each other,” the whistleblower replied.
The whistleblower wants it to be known that “Regardless of my differences with any current or former U.S. Administration, I did it for our country.”
This exchange highlights the new reality on the ground: a coalition of individuals, both inside and outside the system, working together against a common corrupt enemy, emboldened by the knowledge that they now have the backing of the U.S. government.
The story of the whistleblower’s gambit is a powerful testament to the impact one determined individual can have. For years, Enzo Vincenzi’s case was a symbol of systemic failure. Today, it stands as a symbol of a new precedent. The arrest of Celso Gamboa and the ongoing U.S. presence in Costa Rica demonstrate that a well-documented, strategically delivered complaint can indeed pierce the veil of sovereign impunity, especially when the rights of American citizens are at stake. The fight is far from over, but for the first time in a long time, for victims of corruption in Costa Rica, there is a tangible reason for hope. A secret complaint has ignited a fire, and the world is now watching to see what—and who—it consumes next.
