The defense of the Spaniard convicted of killing Arrieta requests that the appeal ruling be overturned.

The legal defense team for Daniel Sancho, a Spanish national serving a life sentence in Thailand for the premeditated murder of Colombian citizen Edwin Arrieta, has formally petitioned the Thai Supreme Court. The filing requests the annulment of the appellate court's previous ruling regarding the case.

This move represents the latest procedural effort by the defense to challenge the conviction and sentencing. The case remains under the jurisdiction of the Thai judicial system as the defense seeks to overturn the findings of the appeals process.
