Authorities are conducting an intensive search for Mariano Ariel Sierra, a 41-year-old tourist from Cañuelas, who disappeared in Iguazú National Park. After his personal belongings were discovered on the walkway to the Garganta del Diablo on Sunday, the Misiones Police and Prefectura Naval Argentina launched operations across jungle trails and the Iguazú River to locate him.
What was found at the scene?
Park personnel discovered Sierra’s belongings on Sunday morning along the path leading to the popular waterfall. The items included his personal identification, a cell phone, 40,000 pesos in cash, and clothing.
Investigators also recovered a water-damaged manuscript written in English, though the specific content of the document has not been released. According to local media, Sierra had been staying at a hotel in Puerto Iguazú since June 25 and was last seen entering the park on Saturday morning.
Why is the search operation complicated?
The search involves patrolling the Iguazú River and navigating various jungle sectors. According to the news portal Que Pasa Salta, the high river volume in the Garganta del Diablo area is making recovery efforts significantly more difficult, as the flow currently exceeds its usual level.
Local media report that investigators are currently operating under the primary hypothesis that the man may have jumped into the water.
What prior incidents have occurred in the park?
The disappearance follows a similar incident in early June involving a Brazilian tourist. That individual reportedly jumped into the falls to retrieve a fallen cell phone, an act captured in a viral 11-second video.
In that instance, the man, wearing a white shirt, descended into a prohibited area to recover his device before climbing back up to continue his tour. Following that event, the Iguazú National Park administration issued a statement reminding visitors that crossing installed barriers is strictly prohibited, even for retrieving lost objects or taking photographs.
What may happen next in the investigation?
The ongoing search could expand to more remote jungle sectors as authorities attempt to find further evidence.
