requested a second expert report by the anthropologist Francisco Etxeberria, who revealed the existence of human bone fragments (which could correspond to 2- and 6-year-old children) in the remnants of the bonfire. A third analysis carried out by José María Bermúdez de Castro confirmed that the remains were human. As a result, Josefina Lamas was dismissed and the investigation concluded. Chain of custody questioned During the investigation of the case by the judge José Luis Rodríguez Lainz, some errors came to light in the chain of custody of the legal evidence related to the remains collected in the bonfire of Las Quemadillas. These remains were sent from Córdoba to Madrid for their study by the forensic anthropologists of the UDEV (Unit of Specialized and Violent Crimes). When Judge Rodríguez Lainz called to testify Josefina Lamas after the refutation of her preliminary report and her retraction, he proceeded to show different images of the evidence. Lamas declared the sample "number 8" missing in the photographs. The hypothetical rupture of the chain of custody of the evidence was one of the fundamental lines of the defence of José Bretón in the trial. Serafín Castro, the chief commissioner of the UDEV at that time, stated at the trial that sample number 8 could have been, for its state, "disintegrated.” Trial Bretón's trial began on June 17, 2013 in the Audiencia Provincial of Cordova with the election of a public jury, consisting of seven women and four men. Bretón denied killing the children or supplying them with pills. Ruth Ortiz said in her statement that she decided to divorce Bretón because her life was unhappy. When Bretón informed her that the children had disappeared, she knew that she wouldn’t see them again. The petrol station workers from Huelva testified in court whereas Bretón's parents and siblings refused to testify. Bretón's brother-in-law claimed that while he did not think Bretón would have killed the children, Bretón was responsible of their vanishing. Some residents around Las Quemadillas stated that they had noticed an unpleasant burnt smell, but did not see any column of smoke. Ruth Ortiz’s cousin, who had visited Bretón while he was in remand stated that Bretón had told him not once but three times that he had killed the children. Psychiatrists and psychologists who examined Bretón diagnosed that he did not suffer any mental disorder. Experts and medical examiner analysed the bone remains
