EIGHT MONTHS LATER — NEW INTERNATIONAL SEARCH EFFORT BEGINS FOR MISSING BRAZILIAN SIBLINGS ÁGATHA AND ALLAN

The disappearance of two young siblings in Brazil has now entered a new phase, with their family seeking help from Interpol after months of searches produced no answer.

Eight months after Ágatha Isabelly Reis Lago, 6, and Allan Michael Reis Lago, 4, disappeared in Brazil, their family is turning to international cooperation in the hope of finally finding the two children.

The siblings disappeared on January 4, 2026, in the rural area of Bacabal, Maranhão, after they went into a wooded area near the quilombola community of São Sebastião dos Pretos.

Despite an enormous search operation involving police, firefighters, volunteers and tracking dogs, the children have not been found.

Now, their case may receive international attention.

THE INTERPOL REQUEST

On September 9, the children’s mother, Clarice Cardoso, formally approached Brazil’s Federal Police to request that Ágatha and Allan be included in Interpol’s Yellow Notice system, an international alert mechanism used to help locate missing people.

The Federal Police said the request would first be reviewed before any formal submission to Interpol.

If accepted, Interpol would then determine whether to publish and share the alert with member countries.

The move represents a significant new step for a family that has spent months searching for answers.

A PHOTO FROM THE UNITED STATES REIGNITED HOPE

The latest development began after Clarice saw a photograph released by authorities in Florida following a major operation that recovered 163 children and teenagers across multiple locations.

She believed one of the children pictured looked remarkably similar to her son Allan.

The photograph gave the family renewed hope that Allan might somehow have been located outside Brazil.

Clarice went to the Federal Police seeking assistance and a possible DNA comparison.

But authorities have now made one point clear: Brazilian authorities say neither Ágatha nor Allan was among the 163 children recovered during the U.S. operation.

That does not answer the central question of where the siblings are.

It simply closes one possible lead.

THE CHILDREN DISAPPEARED WHILE PLAYING

According to Brazilian reporting, Ágatha and Allan disappeared while playing in a wooded area in the rural region of Bacabal.

They were accompanied by their 8-year-old cousin, Anderson Kauã.

Anderson was found alive three days later by people traveling along a rural road, several miles from where the children had disappeared. He had reportedly become lost after entering the forest with his cousins.

The discovery of Anderson gave investigators important information about the children’s final known movements.

But Ágatha and Allan were still missing.

A SEARCH INVOLVING HUNDREDS OF PEOPLE

The search grew dramatically.

Police and firefighters from Maranhão and other states joined volunteers in an operation that at its peak involved nearly 1,000 people.

Search teams used tracking dogs and other resources while authorities also examined waterways in the region.

Investigators searched sections of the Mearim River, including underwater areas, but no trace of the children was found.

At one point, search dogs detected indications that the children may have been near an abandoned house.

The location became one of the most significant leads in the investigation.

However, it did not provide the breakthrough the family desperately needed.

ONE OF THE BIGGEST QUESTIONS REMAINS UNANSWERED

Brazilian authorities have not publicly confirmed a single investigative theory explaining what happened to Ágatha and Allan.

The investigation by the Maranhão Civil Police remains confidential, and officials have not publicly established whether the children became lost, were taken somewhere, or what ultimately happened after they disappeared.

That uncertainty has made the case especially difficult for investigators — and agonizing for their family.

NOW THE SEARCH MAY CROSS BORDERS

The request for an Interpol Yellow Notice could expand the search beyond Brazil.

Such an alert is designed to help police forces in different countries cooperate in locating missing people.

For Clarice, the move comes after months of uncertainty and countless searches.

The U.S. lead that briefly raised hopes has now been ruled out.

But the international search is not over.

Ágatha is six years old. Allan is four.

They disappeared together.

Eight months later, their family is still waiting for the answer to the question that has haunted them since January:

WHERE ARE ÁGATHA AND ALLAN?

And now, their names may be carried far beyond Brazil — as the search for the two missing siblings enters a new international chapter.
