A British helicopter pilot has been sentenced to 20 years in a Spanish prison for the murder of a man he had arranged to meet for a weekend of drug-fuelled sex. Aaron Rainbow, 50, originally from Surrey, was found guilty of stabbing Oscar Tornero, 38, six times after a binge on drugs. The verdict was delivered by a jury three weeks ago, and today, trial judge Carmen Sucias Rodriguez confirmed the maximum penalty for the crime under Spanish law. In her 87-page ruling, she dismissed the defence's argument that Rainbow's drug use should be considered a mitigating factor. In addition to the prison sentence, Rainbow was ordered to pay nearly £470,000 in compensation to Tornero's family and ex-partner, with over £300,000 allocated to his daughter. During the trial, which began on October 8, Rainbow claimed he acted in self-defence, stating that he felt confused and paranoid due to the crystal meth and GHB consumed at Tornero's home in Vallgorguina, near Barcelona. He testified, "I have the feeling I have not been responsible for this," and expressed fears that Tornero was recording their encounter and that strangers were waiting outside to attack him. Rainbow recounted searching for a knife for protection before locking the door. He stated, "My instinct told me I was in serious trouble," but could not recall how many times he had stabbed Tornero. A neighbour who called emergency services reported hearing Rainbow shout, "I’ll f##king kill you," as Tornero attempted to escape the attack. The jury's 8-1 majority verdict was influenced by testimony from another man who had a similar drug-fuelled encounter with Rainbow in London just days before the murder. This individual had warned Rainbow in a WhatsApp message, "I thought you would grab a knife to kill me," highlighting a pattern of violent behaviour. The prosecution described the events leading to the murder as premeditated, stating that both men had arranged to meet for sex and drug use. After the stabbing, Tornero attempted to flee but ultimately collapsed and died from his injuries. State prosecutor Felix Martin increased the prison demand from 19 to 20 years following the jury's verdict, aligning with the private prosecutor representing Tornero's family. Rainbow's defence lawyer argued for his client's acquittal, claiming he was suffering from temporary insanity and acted out of fear. The family of the convicted pilot has likened the case to a "Netflix thriller," alleging that Spanish police mishandled the investigation and failed to examine electronic devices that could support Rainbow's claims of being watched.
