Daniel Sancho condemned to life imprisonment for premeditated murder in Thailand
A Thai judge sentenced Spanish chef Daniel Sancho to life imprisonment for the premeditated killing of Colombian surgeon Edwin Arrieta in August 2023. Evidence of premeditation, including purchases of knives and plastic before the crime, were decisive in the sentence.

Life imprisonment for Spanish chef in Thailand
Daniel Sancho, a Spanish chef and son of actor Rodolfo Sancho, was sentenced to life imprisonment this morning after being found guilty of premeditated murder by a judge at the Provincial Court of Samui. The death of Edwin Arrieta, a successful Colombian surgeon, occurred on 2 August 2023 on the Thai island of Phangan. According to lavozdegalicia.es, Arrieta's body was dismembered into 17 parts, a fact that generated unprecedented media attention in Spain, Colombia and Thailand.
The sentence was reduced from capital punishment to life imprisonment due to the accused's cooperation with the investigation. The judge highlighted the premeditated nature of the murder as the decisive factor. Sancho's defence, led by lawyer Marcos García-Montes, has already announced an appeal, although this will not prevent immediate transfer from the current prison to Bang Kwang penitentiary, known for its worst conditions. Bang Kwang, designed to hold 3,500 inmates, currently houses more than 8,000 people.
Evidence of premeditation
Evidence of premeditation proved decisive in the trial. Hours before the crime, Sancho made purchases that were interpreted as deliberate preparation for dismemberment. A receipt for 1,486.75 baht—approximately 40 euros—documented the purchase of a knife measuring 34 centimetres long and 9 wide, scourers, rubber bands, more than one hundred metres of plastic film, stainless steel mesh, several packets of bin bags in different sizes and gloves. Along with these items, he also bought fruit: watermelon, melon and grapes.
Arrieta's remains were found in a bag that was discovered by chance by refuse site workers in Koh Phangan. Thai police, the prosecution and lawyers for the Arrieta family considered that these premeditated purchases constituted proof that the murder was planned, not accidental as the defence subsequently claimed.
The defence's strategic confusion
Daniel Sancho initially confessed to the murder whilst in custody at the police station where he had reported Arrieta's disappearance. However, his defence changed his strategy for the trial, acknowledging that he had dismembered the surgeon but denying having murdered him. He argued that it was an "accident" following a lovers' quarrel.
In his subsequent version, Sancho claimed that Arrieta was keeping him as a hostage, threatening to make his homosexual relationship public if he did not comply with his demands. Sancho feared that exposure of his sexual orientation would damage both his personal reputation and his family's public image, given that his father is a well-known Spanish actor. "I am guilty, but I was his hostage," Sancho declared, adding that "he forced me to do things I would never have done."
The forensic impossibility of determining the exact cause
Despite the efforts of Thai authorities, the specific reason for death could not be confirmed conclusively. Forensic experts could not establish whether Arrieta died during a fight prior to the dismemberment or during the process itself. The lack of key body parts, such as the torso, prevented conclusive analysis.
Forensic experts considered that death could have occurred as a result of the dismemberment itself, following violent blows to the head that left the surgeon unconscious. That theory would have opened a legal avenue for Sancho's lawyers to consider self-defence, arguing that there was a previous argument in which Arrieta had made death threats against the Spaniard. However, the court considered that premeditation was proved by the purchases made before the fatal encounter.
Requirements for serving sentence in Spain
The legal team for the Arrieta family clarified one of the outstanding unknowns: whether Sancho could serve his sentence in Spain. According to Beatriz Uriarte, lawyer at Ospina Lawyers, the minimum sentence to be served in Thailand is eight years. After that period, Thailand must grant permission for Sancho to be transferred to Spain.
The case has marked a media milestone due to the multiple elements surrounding it: the extreme violence of the crime, the public status of the accused's family, Thai jurisdiction known for the severity of its laws, and the legal complexities arising from the need for international cooperation for any possible future enforcement of the sentence in Spanish territory.
