Desecration of the Arizkun Church

The Desecration of the Arizkun Church is a sequence of attacks that turns a local investigation into a collision between religious folklore, the history of the Agotes, and Amaia Salazar’s own family history. Infant bones placed in the church are first read through the legend of the mairu-beso; forensic testing then produces an unexpected genetic match to Amaia. A later assault targets the church’s long-sealed entrance for the Agotes, making the building’s architecture part of the crime’s message as well as its setting.

The first discovery and the mairu-beso

The inquiry begins with small bones found in Arizkun Church, burned at one end. Jonan Etxaide identifies them as a possible mairu-beso: in the tradition he describes, the object had to come from an infant who died before baptism. Such bones were believed to carry protective or magical powers. One account held that their smoke could drug the inhabitants of a house or even an entire village, allowing those carrying them to commit witchcraft. The object is therefore not merely a relic in the investigation; its meaning depends on the unresolved boundary between religious status, childhood death, and folk practice.

Jonan’s identification also changes the apparent scope of the crime. Inspector Iriarte observes that the remains suggest desecration not only of a church but of a cemetery as well. Jonan’s subdued response—that this is the best-case interpretation—leaves open the possibility that the discovery points to a more extensive violation. The bones make the investigation ask where they came from and why they were placed in a sacred space, not simply who broke into the church.

The Agotes and the church’s divided space

As Amaia and Jonan discuss the desecrations, Jonan sets the history of the Agotes against the present-day crime. Historians disagree about the group’s origins. Theories place their arrival in Navarre during the medieval period, possibly as refugees from war, famine, plague, or religious persecution. They may have been Cathars fleeing the Inquisition, deserters who contracted leprosy in French lazarets, or a mixture of outcasts brought to serve the local feudal lord. Their settlement was concentrated in Bozate, near Arizkun.

Whatever their origins, the Agotes were excluded for centuries. They were restricted to Bozate, barred from owning businesses or marrying outside their group, and pushed into woodworking and leatherworking, trades considered unhealthy. They were required to wear identifying marks and, in some accounts, ring a bell to announce their presence. Their treatment continued inside the church: they had a separate baptismal font, their holy water was discarded, and they were kept from the altar and made to enter by a smaller, separate door. At Arizkun, a grille once divided them from other worshippers. It was later removed because the separation had become a source of shame for local residents.

This history offers a possible context for the desecrations, though it does not by itself identify their perpetrators or settle their motive. The former Agote entrance gives the second attack a particularly pointed geography: the church’s record of exclusion is embedded in its walls, and the attacker will use that very point of division to break back into the building.

Forensic results and an unexpected kinship

The bones’ first interpretation is complicated by laboratory analysis. The police commissioner tells Amaia that Doctor San Martín’s results were repeated three times before they were presented. The remains were sufficiently well preserved to test despite having been burned at one end. The analysis identified them as belonging to a male infant, approximately nine months prenatal or one month old, and dated them to about 150 years earlier, with a five-year margin of error.

The forensic result thus fits the age requirement associated with a mairu-beso, but the routine DNA check brings a discovery the investigators did not expect. The infant’s DNA could not match a living database entry directly; instead, the sample showed a 25 percent correspondence with Amaia. The match does not, on its own, explain the relationship or establish the remains’ identity. It does, however, make the church investigation personal and turns a supposedly ancient relic into evidence of a concealed connection.

Jonan further explains why an adult bone would not qualify as a mairu-beso in the tradition: its significance rests not only on lack of baptism but on the infant’s age and the belief that a newborn’s soul remains in transit between worlds. Folk accounts also describe unbaptized dead children as household protectors. Some families were said to preserve a cradle or set a place for the dead child at the table, while avoiding giving its clothing or name to a new sibling. These beliefs supply a cultural vocabulary for the remains, but they do not resolve the case’s central forensic question: why the bones and Amaia’s DNA should be connected.

The second attack

A further assault occurs while Amaia and colleagues are waiting through the night for laboratory work. Inspector Iriarte reports that someone has driven a Bobcat forklift into the church façade, opening a breach. Another small arm has been left inside, on the altar. Unlike the earlier bones, it is unburned and somewhat different. The new remains make clear that the first discovery was not an isolated placement, while their difference cautions against treating every fragment as identical evidence.

The attack is reported at around three in the morning. Neighbours hear the impact but see no one. The forklift has been driven through the precise location of the former Agote door, where the wall is brick; its forks punch through the masonry. The old entrance is not just an incidental weak point. Its history makes the breach a violent reopening of a doorway once assigned to people whom the church kept apart.

The timing also reveals deliberate misdirection. Fifteen minutes before the church patrol is diverted, an emergency call reports a fire at the Ursua palace, a site linked to the history of the Agotes. The blaze is small: gasoline has been poured over the wooden entrance, which catches fire and is quickly extinguished by the patrol. While officers respond to that call, the church is left without its nearby guard. The paired actions—setting a fire at the palace and using heavy machinery at the church—show how the attacker exploits both local associations and police procedure.

The desecration as a crime signature

The attacks acquire further weight against the broader investigation into severed arms. In a related murder inquiry, Amaia initially considers whether an arm cut from a victim might have been removed for a ring or to prevent identification, but finds those explanations inadequate in the circumstances. Investigators note that postmortem amputation of the same arm, with the limb missing from the scene, is the recurring element that does not fit the usual pattern of domestic abuse murders. A word scratched into plaster with a toothbrush handle—TARTTALO—appears in another case and is reported again, in the same unusual spelling and handwriting, after a murderer dies by suicide in his cell.

The church remains are therefore encountered within a case in which the violent act and its added mark must be distinguished. One perpetrator may kill impulsively while another removes the arm as a trophy; investigators reason that the person who takes it must be able to recognize, profile, or follow killers. That distinction matters to the desecrations too: the bones, their placement on or within the church, and the targeted entrance are not interchangeable details but clues whose meaning depends on who put them there and what pattern they belong to.

The event’s decisive reversal is that an investigation initially framed by medieval exclusion and folk belief produces a genetic link to Amaia, then continues through a calculated nighttime assault that physically targets the church’s history of segregation. The remains invite explanations in religious and folkloric terms, but the repeated attacks, diversion, and forensic match demand a criminal account as well. Arizkun Church becomes both a violated sacred place and an evidentiary scene where the past is not safely past: it survives in the bones, the blocked doorway, and the family connection the tests bring into view.
