Baztán–Lesaka Secret Cult

The Baztán–Lesaka Secret Cult is a clandestine network organized around occult teachings, ritual offerings, and an obligation its members cannot escape. First described as a welcoming search for spirituality and tradition, it is revealed as a group that converts belonging and promised power into participation in human sacrifice. Its beliefs give the cult a rationale for treating children as offerings; its doctrine of debt makes that violence persist long after members appear to have dispersed.

Formation and Leadership

The group’s origins emerge through the account of a former member who arrived in the area after university, during San Fermín. A young woman invited him to a communal house shared by friends. At first, its residents seemed to be exploring traditional knowledge, human nature, and natural forces. They cultivated cannabis, listened to the wind and the earth, danced around a fire, and held talks for possible recruits, including local people and tourists drawn by spirituality, witchcraft, or spiritualism. The informant stayed after the summer, and says that this was when the commune began to reveal its real character.

The group’s authority centered on Xabier Markina, whom members knew as Tabese. The informant recalled him arriving unpredictably, with wealth, polished manners, and an allure that made the house’s occupants eager for his return. He presented himself as a guide to ancient witchcraft and forgotten religion, teaching that offerings could awaken extraordinary presences rooted in the region. He invoked megalithic monuments and ley lines, and claimed that people had long negotiated with powerful beings through offerings. In the former member’s account, the promised benefits began with small animal sacrifices and grew into demands for more.

The cult also made recruitment social and intimate. Its first setting was not described as an overtly coercive institution but as a community offering affection, shared purpose, special knowledge, and access to power. A later explanation of destructive sects describes how leaders identify followers’ vulnerabilities, then exploit them and rebuild their sense of importance within a group that appears to love, protect, respect, and listen to them. That account helps explain the cult’s hold on its members without making their participation uniform: some were devoted, while others, the witness said, did not know what their husbands intended.

Doctrine and Sacrificial Rules

The group’s doctrine turned sacrifice into both a means of obtaining favors and a supposed way to restore balance between hostile forces. The witness believed that actions in the house had awakened Inguma and other antagonistic forces, and interpreted later suffering—including his own son’s illness and death—as consequences of what the group had done decades earlier. These are the witness’s beliefs, not independently established supernatural facts; within the cult, however, they gave sacrifice the force of a binding obligation rather than a single criminal act.

The testimony describes a prescribed victim profile. A child had to be younger than two, a girl, and unbaptized. The witness said the group regarded the child’s soul as still in transition before the age of two, making the child a more effective offering; baptism was excluded because the cult considered it a commitment to another god. He also said that sacrifices were organized by sex and age, with victims selected in matching circumstances until a cycle was complete. The stated age rule is echoed elsewhere in the investigation: children were believed to move between worlds and to serve as vehicles for communication with spiritual realms. These ritual explanations belong to the group’s own system of meaning.

The witness described the Lesaka sacrifice as involving a child whose parents offered and killed her, with other members participating. He said she was to be sacrificed to evil and to Inguma by being deprived of air, after which her body was to be surrendered as an offering. He could not explain the purpose of that final act, and said that the child’s body was taken away. The group began to break apart within days and its members disappeared in less than a month, but the dispersal did not, in his account, end their allegiance.

Debt, Membership, and Later Connections

The cult’s most durable rule was that nobody could leave without eventually paying the debt. The former member said dispersal had been part of the agreement, not a release from it: members remained part of the group, and Inguma would collect an offering sooner or later. He had built a prosperous life after leaving, married, and had a son. When that child developed cancer, a former member encountered at the hospital offered a way to save him in exchange for another sacrifice. The witness considered the demand while facing his son’s illness, then described himself as still paying for the earlier crime. His account makes the doctrine of debt a mechanism for reaching former members through grief and fear, even after the original commune has vanished.

The later investigation finds links between this history and a wider network. Amaia Salazar tells Marina Lujambio and her father that Berasategui was connected to a grief-support group at Argi Beltz, and that parents in several cases had ties to that group and to lawyers in Pamplona. She also describes the attempted removal of a body from a funeral home, the opening of the Esparza family tomb, and the related events in Igantzi. In a separate account, a witness identifies Xabier Markina as the spiritual leader of a sectarian group established in Lesaka and Baztán in the late 1970s and early 1980s, and says members from Lesaka sometimes visited the group at Argi Beltz.

That witness identifies the Martínez Bayón family as members of the original group and says their fourteen-month-old daughter supposedly died during a trip to the United Kingdom that she never made. The investigation finds no death certificate, autopsy report, burial record, or entry for the child in her parents’ passports. The witness also identifies Amaia Salazar’s mother among those associated with the Argi Beltz group. Together, the testimony and missing records extend the inquiry beyond a single ritual in Lesaka, while leaving the precise role of every person to be established rather than assumed.

Investigation and Exposure

Amaia Salazar comes to suspect that the cult remains active, not merely a relic of events thirty years earlier. She argues that Berasategui’s death in prison and Rosario’s death were not simply their own decisions, and that the witness’s account describes a group that may now be more organized and experienced. In her interpretation, the river murders of girls represent unfinished work. Sarasola suggests that women, their families, or their partners may have incurred debts to the group, and that women unable to have children—or whose children were considered too old—could themselves be made offerings to a lesser deity. These explanations are presented as investigative hypotheses about the network, not as proof that every suspected connection is established.

The investigation also examines how the cult could make use of people whose vulnerabilities were already present. Sarasola’s account is that a destructive sect does not necessarily create a follower’s underlying pathology; rather, it can redirect a person’s obsessions and make that person a loyal servant. The group’s promise of a valued place in the world thus sits beside its demands for obedience and sacrifice. What begins as a community of believers can become a structure in which affection, status, and protection serve the leader’s purposes.

After the confrontation surrounding Jonan Etxaide’s murder, the authorities move against several points in the network. The lawyers Lejarreta y Andía are arrested, and the Foral Police search Argi Beltz in Orabidea, where early indications suggest Rosario may have hidden during her disappearance. A nurse, Hidalgo, is found dead at her home in Irurita, while Inma Herranz claims she acted under coercion. Investigators face weeks of work identifying and dating the remains of girls found around a coffin that proves empty. A search order is issued for Xabier Markina, who is identified as Tabese. The empty coffin makes the cult’s long-running logic of concealed bodies concrete: the inquiry has exposed a network, but the whereabouts of its leader and the identities of the remains still demand answers.
