The Esther López Case: Two Years Without Evidence and a Trial on the Horizon

On February 5, 2022, the body of Esther López was found in a ditch at the exit of Traspinedo (Valladolid), after a 23-day search involving Guardia Civil helicopters and drones that flew just 300 meters away. A plumber from Salamanca discovered the body. Since then, the investigation has identified Óscar, a friend of the victim, as the main suspect, but neither the judge nor the prosecutor has agreed on precautionary measures against him. After more than two years of proceedings, the UCO (Organized Crime Unit) has failed to build a coherent account of events, and the defense has already requested dismissal.

An Autopsy Without a Defined Crime Scene
The autopsy determined that Esther died from multifactorial shock, a combination of polytrauma, hypothermia, and alcohol and drug consumption, but could not determine whether the injuries resulted from being run over, falling, or assault. The initial forensic report from April 2022 already raised doubts about the mechanics of the injuries. The victim's coat showed traces of her own blood on a finger and under her nails, but there were no blood traces on the suspect's vehicle, a Volkswagen T-ROC, which was inspected in January 2022 without finding defects. It was only months later that the Guardia Civil began pointing to alleged damage to the car, supposedly compatible with being run over. However, expert reports by the defense, conducted by industrial engineers, maintain that the vehicle had no damage on the date of the crime and that subsequent marks did not match the injuries.

The Motive: Drugs, Gender Violence, or Neither?
One line of inquiry gaining strength in the data analysis is the possible involvement of a drug environment. According to statements collected in the case file, Esther had a conflict related to the theft of a significant amount of narcotics, which may have motivated an assault prior to her disappearance. However, this angle has barely been investigated by the UCO, which from the start focused the case as a misogynistic crime. The Delegate against Gender Violence confirmed two days after the body was found that Esther had been murdered, a statement that, for many analysts, conditioned the investigation from the beginning. Supporters of Óscar's guilt argue that Esther's saliva found on his jacket and the positions of the mobile phones during the early hours are sufficient evidence. Those defending his innocence reply that the saliva may be due to accidental contact and that cellular antennas have a margin of hundreds of meters, insufficient to place Óscar at the scene of the accident.

The Search Scandal and Missing Evidence
The location of the body was a logistical disaster. The Guardia Civil command post was installed 200 meters from where the corpse lay, and drone flights passed overhead without detecting it. A plumber trinc the case on his own found the body in the first zone he inspected. This initial failure provoked media pressure that, according to critics, led commanders to seek a quick culprit, fitting Óscar into the gender violence profile. The investigation has spent tens of thousands of euros on irrelevant analyses, such as studying the washing of the suspect's car at a car wash days later, for which no conclusive conclusions have even been presented. Meanwhile, the court has dismissed key tests that could exonerate Óscar, such as an independent expert assessment of the vehicle's damage, despite the defense providing reports from accident reconstruction experts.

A Trial Without Solid Evidence: Precedent of Other Media Cases
The prosecutor in the case has acknowledged in other causes, such as that of Dolores Vázquez, that investigators sometimes become convinced of a suspect's guilt before having proof. In that case, the accusation was based on "personal conviction" and turned out to be a mistake. In the Esther López case, the lack of a coherent account of events by the UCO, the absence of biological remains of the victim in the car or on Óscar's clothes (except saliva), and the lack of direct witnesses make many experts consider a conviction unfeasible. The defense has presented a simulation of the accident demonstrating that the T-ROC could not have caused the injuries at the estimulante ilegal claimed by the prosecution. The judge has so far refused to repeat the expert assessment, resulting in a technical tie between prosecution and defense.
