Madrid’s courts have released José Trinidad Márquez, better known as the Camaleón Criollo, after police caught him trying to swindle 120,000 euros from a local businessman. More than 20 open cases against him are pending in the city, yet the 72-year-old Venezuelan fraudster left court facing only provisional charges. Investigators and victims have grown used to the pattern.
Márquez was most recently arrested in the Chamartín district. He posed as a Pemex executive and promised lucrative contracts. The intended victim grew suspicious and alerted police before the meeting. Officers detained Márquez during the attempted handover, but he was released within two days after a brief court appearance. In economic crime cases like this, suspects are often granted provisional liberty while they await trial.
Information from ABC, Márquez is considered Spain’s most notorious and active scammer of his kind. His criminal career spans at least 35 years, longer than previously reported.
For more than thirty years, Márquez has built a reputation as Spain’s most persistent corporate impostor. His approach is straightforward: he contacts executives at industrial firms, claims to represent oil companies such as PDVSA or Pemex, and offers access to rigged tenders for shipbuilding contracts. He arranges meetings in luxury hotels, with forged documents and a polished appearance. He is always in a suit, with a convincing story. Evidence reviewed by EL PAÍS says that in 2024 alone, he targeted Samsung and Siemens. The same evidence names Mitsubishi. It also names Rolls Royce and Morgan Stanley.
Despite his lengthy criminal record, Márquez has rarely spent time in prison. Judicial sources call him a "classic" of Madrid’s courts; by the end of last year, his name had appeared in at least 20 separate proceedings at Plaza de Castilla. Convictions remain rare. His only confirmed jail time came about fifteen years ago, when he served a sentence in Estremera prison.
Spanish press reports that Márquez has impersonated an executive of PMI Holdings Petróleo España, a Pemex subsidiary, since 2021. He arranged meetings with victims in late August 2026. A potential victim alerted police on August 31, prompting a planned sting operation in Chamartín.
The Camaleón Criollo’s scams have attracted plenty of media attention. Over the years, he has tried to deceive Portugal’s largest bank. A Partido Popular deputy was another target, as was Real Madrid’s vice president. In one case, he stole the identity documents of a Móstoles resident, Domingo Galán, and used their physical resemblance to further his schemes. The Venezuelan outlet Armando.info gave Márquez his nickname, comparing him to the basic character in the film "Catch Me If You Can."
Márquez manages his personal life as carefully as his scams. Last year, he was found living with his partner and their child in a Chamartín apartment. He is often seen in the upscale Goya area of Salamanca. His ability to blend into Madrid’s business circles has allowed him to operate with surprising freedom, even as his reputation grows.
Spain’s justice system continues to process Márquez’s many cases, while economic crime laws often favor provisional release over pre-trial detention. That legal structure, together with his ability to avoid lasting consequences, leaves room for him to keep trying. The situation echoes frustrations over other high-profile legal standoffs, including those involving border tensions and political disputes reported earlier.
The Camaleón Criollo’s persistence exposes a weakness in Spain’s approach to white-collar crime. Someone with a decades-long record of deception can repeatedly walk free, reflecting both his skill and the inertia of the institutions meant to stop him. Until the courts deliver a decisive verdict, Márquez’s case remains a warning for Spain’s business elite and a reminder that the risk of fraud is a constant reality for some.
