The Ainhoa Tomb Explosion is the failed nighttime attempt by Yolanda Berrueta to open her children’s grave with explosives. It left her gravely injured, shattered the tomb and neighboring monuments, and brought investigators to the damaged coffins inside. What began as an act driven by grief and a belief that her children’s bodies had been taken became a physical examination of the grave—and a turning point in the investigation.

Causes and Background

Yolanda had repeatedly told the priest who knew her family that her children were not in their tomb. She came to the churchyard each week, insisting that a mother could feel the absence of her children’s bodies. The priest understood the depth of her grief but rejected her claim: he had officiated at the funeral and watched the coffins lowered into the grave. To him, the burial was witnessed and settled; to Yolanda, the grave concealed an intolerable uncertainty.

The scene carries an earlier account of infant loss that sharpens the stakes without resolving them. Judge Markina had described how, when he was twelve, his three-week-old brother died unexpectedly. He remembered his mother trying to revive the baby, then grieving so intensely that she withdrew from her husband and surviving son and was admitted to a psychiatric clinic after attempting suicide. His story makes the force of bereavement legible, while the explosion shows how grief can be dismissed as delusion even when the grave itself has not been examined.

When Iriarte called Amaia Salazar, Yolanda was already in critical condition. She had tried to open the tomb of her children in Ainhoa with some kind of explosive, losing several fingers and an eye. The call interrupted Amaia’s rare, peaceful evening at home with James. She ordered Etxaide to collect her, and left to reach the cemetery.

The Attempt and Its Failure

The charge was placed in a hollow in the tombstone and connected to a length of delay cord and an old manual detonator. Investigators estimated that it contained about two hundred grams of explosive, possibly Goma-2. The family’s ownership of a mine near Almandoz raised the possibility that the material had come from mining supplies, but routine controls made a recent theft difficult: since the Madrid attacks, explosives for each blast were transported under guard, and unused material was recorded and destroyed at the site. Investigators instead suspected that the packaging belonged to old explosives, perhaps retired before those controls and forgotten somewhere Yolanda could reach them. Their age mattered. Deterioration and moisture had made the charge unreliable, but Yolanda had no expert’s eye for signs such as lost malleability or a sweating surface.

After activating the detonator, Yolanda waited. When the explosion did not follow, she approached, apparently believing that the rain-soaked ground had dampened the cord or the explosives. The charge detonated as she came near. The blast cost her two fingers outright; two others were found stuck to the opposite mausoleum. She also suffered burns and damaged eardrums, and doctors doubted that her injured eye could be saved. Though conscious, she dragged herself to the edge of the grave to check whether her children were inside.

The blast’s damage spread beyond the target. It broke crosses and columns on neighboring graves and sent planters and flowerpots flying. The slab over the Tremond Berrueta tomb, already considered exceptionally brittle, collapsed into fragments; the largest piece was less than fifty centimeters across. Blood mixed with rainwater at the foot of the grave, while the scattered debris exposed the burial chamber to the investigators arriving at the scene.

What the Open Grave Revealed

Under a blue tarpaulin, the damaged burial chamber offered a stark contrast between the orderly certainty of a funeral and the disorder left by the blast. Two old, dark adult coffins had been struck by falling stone. Nearby, a small metal-looking casket, apparently intended for ashes, lay overturned and ajar. The two small white coffins had suffered worse damage: rubble crushed one, splitting its side and exposing what investigators recognized as a baby’s hand; the other had overturned, leaving its contents displaced beside it.

The child still visible in the grave had been buried in white, but mold had darkened the clothing and blackened the baby’s face. The sight made the inspection more than a response to vandalism or an attempt to verify a burial. It placed the children’s remains directly before the investigators, while leaving open the question Yolanda had insisted upon: whether both bodies were there.

Amaia Salazar rejected the accusation that she should be satisfied by what the explosion had exposed. She told the priest that this was precisely what she had tried to prevent, and that those who claimed to care for Yolanda should have opened the grave earlier rather than leave her suffering with an unanswered fear. Her rebuke challenged the distinction the community had drawn between compassion for a grieving mother and taking her claim seriously enough to investigate.

The later evidence transformed the meaning of the blast. Recovering in hospital, Yolanda was alert and oriented despite her bandages. She acknowledged that fear and medication had led her to confuse the coffins, but maintained that she had been right about the essential fact: someone had taken one of her babies. She accepted that she herself had been responsible for the dangerous attempt, yet recognized that a peaceful inspection might have confirmed that some remains were present without revealing that the girl was missing. The explosion had cost her fingers and an eye, but the forced opening of the grave exposed a disappearance that could otherwise have remained hidden—and connected Yolanda’s claim to another mother in Elizondo whose child was also gone.

Aftermath and Narrative Significance

The explosion is not the investigation’s final image. Later, at Muniartea Bridge, Amaia watches the Baztán River run quietly after its destructive rise and wonders whether it has been cleansed and the offense washed away. At home, she collapses into Engrasi’s arms and weeps for what has been lost and violated, for death, bones, and blood. The sequence places Yolanda’s injured body and opened grave within the wider accumulation of the case’s damage: exposure brings answers, but does not undo what the search has cost.

Amaia eventually gathers herself to act again. Among the calls she makes is one to Elena Ochoa’s daughter, telling her that her mother did not die by suicide and that the letter she left helped bring the child-killing sect to the authorities’ attention. That broader resolution does not erase the explosion’s particular consequence: Yolanda’s claim was no longer only the grief-stricken assertion of a mother whom others had dismissed. The ruined tomb made the question of the missing child impossible to leave buried.
