Ramón Quiralte’s suicide in prison turns a suspected pattern of intimate-partner killings into a more disturbing investigation: Quiralte dies after poisoning himself, but the word he leaves behind points beyond his own crime.

The poisoning and death

Before entering the prison, Amaia Salazar had asked the judge to keep Quiralte under close surveillance. She and Jonan Etxaide hurried back after learning that Quiralte had swallowed poison and was unconscious amid vomit and blood. By the time Amaia reached his cell, he lay intubated and motionless on a stretcher. The prison doctor explained that Quiralte had mixed his dose in a cyclist’s water bottle and taken it soon after arriving in the cell. The corrosive poison had caused severe burns around his nose and mouth. Although the medical team had responded quickly, they had been unable to save him; the doctor described the self-inflicted poisoning as an especially agonizing death.

The message in the cell

The cell contained a second message alongside the evidence of Quiralte’s death. On the wall of the lower bunk, he had written TARTTALO. Amaia had to bend to see it; Jonan followed her gaze and noticed the substance before the prison doctor confirmed that Quiralte had written the word in feces. The doctor described writing with filth as a common form of protest in prison, but could not explain what this particular word meant.

The inscription turns the suicide from a closed act of violence into a possible communication. Quiralte leaves no note that explains his purpose; instead, the word is both conspicuous and opaque, carrying a meaning the prison staff cannot read. Its material matters too: a familiar prison protest practice becomes the medium for a name—or a sign—whose significance exceeds the cell.

That word had already appeared in another prisoner’s cell. Earlier, a director had reported that a man scratched an apparently senseless mark into plaster with the handle of his toothbrush. Though the wall had been painted over, the grooves remained legible in a photograph: TARTTALO. The recurrence links the two deaths through a distinctive written trace, while leaving open who authored or transmitted it and what the term signifies. Quiralte’s final message therefore supplies no simple confession; it deepens the investigation by making the same unexplained mark appear where another killer died.

The pattern behind the inscription

The word in Quiralte’s cell gained investigative weight because it had appeared in another prisoner’s cell, in the same unusual spelling and handwriting. Amaia Salazar noted that the common form used one “t,” whereas both inscriptions used two. By then she had identified three cases and suspected there might be more. The mark suggested that the deaths were connected, but the repeated spelling alone did not explain who had made it or how the cases were linked.

The missing arm supplied a second, more disturbing point of comparison. In each case, a victim’s arm had been amputated after death, and the limb was never recovered. At first, Amaia treated the mutilation in Quiralte’s case as possibly incidental: perhaps the killer had removed a hand to take a wedding ring or frustrate identification, though neither explanation made much sense in the victim’s own home. The comparison with other murders changed its significance. The amputation was not simply part of the killers’ violence; its recurrence, including the removal of the same arm, suggested a distinctive signature.

Jasón Medina’s confession sharpened the distinction between the individual killer and the person behind that signature. Medina admitted that he had raped Johana Márquez, strangled her with his bare hands, and sexually assaulted her after death. But when questioned about the missing arm, he was bewildered and did not know how it had been removed. He had left to fetch a rope so he could imitate a murder he had read about; when he returned, Johana’s arm was already gone. Amaia remembered him crying through the interrogation, his face streaming with tears and mucus, and regarded his confusion about the amputation as genuine.

That sequence made the repeated mutilation difficult to attribute to spontaneous imitation. Medina’s violence was impulsive, and the arm had disappeared while he was away, yet the person investigators called the Tarttalo had been present at precisely the right moment to take it. Amaia and her colleagues inferred that the unknown figure had already known Medina and was following him. The inference reframed the cases: the intimate abusers’ murders and the recurring removal of an arm might belong to different stages of a crime, with the second act imposed by someone who could identify and track killers. Quiralte’s death thus left investigators with a sign that connected the cases, while the larger pattern pointed toward an unseen operator.

The confession’s boundary

Quiralte had been found close by, drunk and still stained with his wife’s blood. He confessed to killing her immediately, but denied any part in the amputation. The cut ran from the elbow and had been made with something toothed yet knife-sharp, such as an electric carving knife or jigsaw. That detail made the severing look like a separate act from the killing he admitted to: the confession established his responsibility for the murder, but left the missing arm unexplained.

Amaia initially considered whether the hand had been taken for a wedding ring or to prevent identification, while doubting that either explanation made sense in the victim’s own home. Quiralte’s later death closed off the possibility of questioning him further. The suicide therefore leaves a double limit on what his confession can establish: he acknowledged the intimate violence, yet the recurring removal of an arm and the inscription in his cell point to a dimension of the crimes his admission did not resolve.
