BARRA DE VALIZAS 2014 — Almost 8 Years Without Answers… Until a Backpack Revealed the Culprit
BARRA DE VALIZAS 2014 — Almost 8 Years Without Answers… Until a Backpack Revealed the Culprit

A Quiet Walk on a Summer Afternoon
Barra de Valizas is a small, serene coastal resort in the Rocha Department of Uruguay. Known for its expansive sand dunes, unpaved streets, and modest houses, it is the kind of quiet retreat families choose specifically to escape urban noise. For fifteen-year-old Argentine teenager Lola Chomnalés, visiting the peaceful resort to spend the end-of-year holidays with her godmother was a cherished tradition.
On the afternoon of December 28, 2014, Lola set out from her godmother’s house for a casual walk along the beach. She packed a pink backpack containing a few personal items: her wallet, ID, a towel, a bottle of water, a book by Julio Cortázar, and a modest amount of cash. In a seaside village celebrated for its safety, a short stroll along the coast seemed entirely harmless. However, when evening arrived and Lola had not returned, casual concern rapidly escalated into an active search.
A Community Shaken to Its Core
Local authorities, emergency responders, and dozens of resident volunteers scoured the coastline, searching the dunes and coastal paths linking the surrounding villages. For two days, desperation mounted until searchers made a heartbreaking discovery. Lola’s body was found semi-buried in a sand dune roughly one hundred meters from the shoreline, almost invisible to anyone not actively searching the area.
An autopsy revealed that she died from asphyxiation caused by pressure against the sand, bearing minor injuries from a sharp edge on her neck and arm. Notably, initial forensic reports indicated no signs of sexual violence. The brutal crime had occurred in broad daylight along a popular holiday stretch, yet no eyewitnesses had come forward. In a tight-knit community accustomed to quiet summer getaways, the absence of clear leads generated immense anxiety, leaving residents looking at one another with growing unease.
Initial Dead Ends and the Clue in the Dunes
Early investigative efforts followed standard protocols, focusing first on those closest to the victim. Police briefly detained and questioned Lola’s godmother and her husband. Having found no evidence connecting them to the crime, authorities cleared them of suspicion.
Investigators then shifted focus toward local accounts describing a suspicious man seen near the area around the time of the disappearance. A composite sketch led to the temporary arrest of a local handyman known locally as “Conejo.” However, after extensive questioning and a lack of physical evidence, he was released without charges. The investigation stall left the town shrouded in lingering tension and unanswered questions.
Days after the body was recovered, search teams made a crucial breakthrough nearby, locating Lola’s pink backpack buried in the sand. Inside, investigators found her ID card, towel, and personal belongings, though her cash was gone. Forensic specialists successfully extracted a male DNA profile from the ID card and towel. This genetic signature, belonging neither to Lola nor any early suspect, became the single most reliable piece of physical evidence in the case.
Years of Silence and Family Persistence
As months stretched into years, national media attention gradually cooled, but Lola’s family remained steadfast in their pursuit of justice. Supported by legal counsel, they maintained active court petitions, ensuring the case file remained open and pushing for further reviews.
During the ongoing proceedings, investigators pursued a parallel line of inquiry, believing more than one individual might have been involved in the crime or its subsequent cover-up. This effort focused on a local man known as “Cachila,” who was accused of accessory after the fact due to inconsistent statements regarding his movements on the day of the murder. Though initially acquitted by a trial court, an appellate review subsequently overturned the ruling, sentencing him to prison for concealment within a gender-based violence framework.
The Breakthrough in the Laboratory
While legal proceedings continued, the primary perpetrator remained unidentified for nearly eight years. The crucial breakthrough came not through traditional field interrogation, but through systematic forensic matching. A geneticist systematically cross-referenced the unidentified DNA profile from the pink backpack against Uruguay’s national penal database every time a new offender entered the system.
In 2022, an individual arrested on entirely unrelated charges provided a DNA sample that yielded a partial match—indicating a close familial relationship to the unknown individual whose profile was preserved on Lola’s belongings. Further genealogical tracing and familial testing led authorities directly to Leonardo David Sena, a man with prior convictions for sexual assault and domestic violence.
The Trial and Final Verdict
Sena was arrested in May 2022, nearly eight years after the crime took place. During legal proceedings, Sena claimed he had accidentally cut his hand while working and later stumbled upon the pink backpack abandoned in the sand, admitting to taking the cash while denying any involvement in the murder.
However, scientific evidence directly contradicted his account. Forensic experts demonstrated that Sena’s DNA was mixed directly with Lola’s biological material on her belongings, indicating direct and forceful contact rather than mere brief handling of an abandoned bag. Furthermore, employment records established that Sena’s work break aligned precisely with the estimated time window of the crime, and his self-reported location placed him in close physical proximity to where Lola was killed.
Evaluating the comprehensive physical, temporal, and location evidence, the court rejected the defense’s claims. In April 2024, the judge found Leonardo David Sena guilty of aggravated homicide, sentencing him to 27 years and 6 months in prison. Nearly a decade after a peaceful beach walk turned into a national tragedy, the combination of persistent family advocacy and forensic science finally brought the long-awaited legal resolution.
