The Infant Tomb Looted and Right Arm Taken is the clandestine excavation of a baby’s grave beneath a house in the Baztán Valley. The removal of the infant’s right arm turns a hidden burial into a crime scene and supplies a material clue that will connect the grave to a family secret.

The excavation

An unidentified person locates the grave by following the line that rainwater has drawn in the earth beneath the house’s eaves. Kneeling at the spot, the intruder takes a small garden shovel and pickaxe from beneath their clothes and chips through the compacted dark soil. The account slows over the work: the earth comes away in damp, soft clods, and the excavator removes it carefully, a few centimeters at a time, until fragments of blackened, rotting cloth emerge.

The body and the missing arm

Working by hand, the excavator uncovered a blanket that crumbled at a touch and beneath it a body wrapped in waxed cloth. Almost nothing remained of the cord that had bound the bundle, though its pressure had left a deep mark in the fabric. The excavator felt for the edge of the wrapping, found its folded layers, and tore the shroud open.

The infant lay face down, as if cradled by the earth. Its bones and the cloth were well preserved, darkened by the soil of the Baztán Valley. The excavator pressed the tiny torso against the ground and wrenched off the right arm; the small clavicle broke with a faint crack. Startled, the excavator stepped back, then gathered the bones beneath their clothes, gave the grave one last look, and pushed the earth back into it with their feet. The burial was concealed again, but the missing arm made the desecration a source of evidence beyond the grave.

The grave and the family secret

The later records make the buried infant legible as more than an anonymous victim, though they do not settle every circumstance of the child’s death. Rosario Iturzaeta’s obstetric file lists a natural twin birth in 1980: two apparently healthy girls, with no names recorded. A separate certificate identifies a newborn daughter of Juan Salazar and Rosario Iturzaeta and gives the cause of death as crib death. The distinction between the apparently healthy twins and the later death record leaves a gap that the paperwork does not explain.

That gap is widened by the family’s account. Amaia Salazar says that her mother concealed the birth from the family, that neither she nor her sisters knew of the child, and that the birth certificate contained irregularities. Her relatives recall attending a burial, but the coffin was closed and they did not see the body. Amaia argues that the conflicting explanations of the death, the concealed birth, and the bones found in strange circumstances together make the newborn’s birth and death suspicious. The identification is therefore supported by converging records and testimony, while important details remain unresolved.

The infant’s age also gives the severed arm a particular cultural resonance. Jonan Etxaide explains that a mairu-beso was believed to derive its power from the remains of a child who died before baptism, and that the relevant child had to be a fetus, stillborn, or dead in the first months of life; an adult’s arm could not qualify. In folk belief, such a child’s spirit remained between worlds and might protect the family home. The grave’s infant remains thus connect the physical evidence to a belief about vulnerable dead children, without establishing that the belief itself explains the crime.

The arm also belongs to a wider criminal pattern. Amaia Salazar links the infant remains to the murders of Johana Márquez and Lucía Aguirre, whose bodies had each been subjected to the same post-mortem amputation from the elbow, with the forearm missing. She notes that the detail in Johana’s case had been withheld from the press, while the Logroño murderer’s prison message matched another suspect’s in wording and unusual spelling. These correspondences lead her to suspect a single orchestrator whose intervention joins otherwise distinct killers and cases; the stolen arm is both a desecrated child’s remains and a clue to that concealed network.

Historical memory and the meaning of the remains

The arm’s significance rests on a folk belief that made an infant’s death before baptism—not merely the child’s age—a condition of the mairu-beso’s supposed power. Jonan Etxaide explains that the remains had to belong to a fetus, a stillborn child, or an infant who died in the first months of life; an adult’s arm could not serve the same purpose. The belief placed the unbaptized child between worlds and sometimes cast its spirit as a guardian of the family home. That tradition gives the stolen arm a ritual meaning within the investigation, but does not prove why the grave was opened or who took it.

The investigation also sets the desecration against the history of the agotes, a people whose origins remain disputed. One account traces their arrival in Navarra to medieval flight from war, famine, plague, and religious persecution; other theories describe them as Cathars, deserters, or a mixed population of outcasts brought to serve a local feudal lord. For centuries they were confined largely to Bozate and barred from living elsewhere, marrying outside their group, or running businesses. Their clothing had to carry an identifying mark, and they were made to ring a bell to announce their presence. Although they were Christians, church practice kept them apart: they had a separate baptismal font, were denied access to the altar, and in Arizkun were separated from other worshippers by a railing and directed through a smaller door. The railing was later removed as a rejection of the shame attached to that treatment. This history supplies a setting of religious exclusion for the story’s concern with sacred places and marginalized dead, but the evidence does not establish that agote persecution caused the infant’s burial or its later desecration.
