Where Is Marta? (¿Dónde está Marta?)

What Is the Series About?

Where Is Marta? (¿Dónde está Marta?) is a three-episode Netflix documentary series directed by Paula Cons and released on 5 November 2021. It examines one of the most haunting and still-unresolved criminal cases in contemporary Spanish history: the disappearance and presumed murder of Marta del Castillo Casanueva, a 17-year-old schoolgirl from Seville, Andalusia, who vanished on 24 January 2009 and whose body has never been found. The series was the first docuseries to address the case in this format, and it topped Netflix's Spanish charts almost immediately upon release.

The Case

On the evening of 24 January 2009, Marta del Castillo Casanueva left her family home in Seville to meet Miguel Carcaño, described in reports as her boyfriend or ex-boyfriend at the time. She never returned. Her disappearance set off a wave of public anguish across Spain, and the ensuing investigation became one of the country's most scrutinized criminal proceedings.

Approximately 20 days after Marta vanished, police uncovered evidence that led to the arrest of Carcaño and a wider group of associates. In total, five suspects became entangled in the legal proceedings, which unfolded across both a juvenile court process and an adult criminal trial — resulting in what multiple sources describe as two sentences and a series of contradictory outcomes.

Miguel Carcaño confessed to involvement in Marta's death, but his account was riddled with contradictions. Over the course of the investigation and trials, he provided multiple conflicting versions of events, including different accounts of how and where Marta's body had been disposed of. Despite extensive searches — some prompted by Carcaño's own statements — her remains have never been recovered. This single fact has kept the case permanently open in the public consciousness and in the Spanish legal system.

Carcaño was convicted of murder and received the principal sentence in the case. A second defendant, known as El Cuco (Jorge Ignacio C.), was convicted of encubrimiento — cover-up — for his role in concealing the crime. Other named defendants in the broader proceedings included Francisco Javier Delgado, María García Mendaro, and Samuel Benítez; some of these defendants were acquitted. The exact length of Carcaño's prison term is not confirmed in the verified sources available, and his current incarceration status cannot be independently confirmed at the time of this writing.

The absence of Marta's body remains the central wound of the case. Without remains, key forensic questions cannot be definitively answered, and the investigation has continued to attract public and media scrutiny for more than 15 years. The family's sustained campaign to find Marta and obtain answers has made the case a defining story in Spain's recent true-crime landscape.

Production

The series was directed by Paula Cons, a Spanish filmmaker whose approach centers the documentary around the case's enduring emotional and legal complexity rather than a straightforward crime narrative. The three-episode format allows for a structured examination of the key phases: the initial disappearance and investigation, the criminal trials and their contradictions, and the unresolved aftermath.

The series is described by reviewers and by Netflix's own synopsis as the first docuseries to address the Marta del Castillo case in this format. Paula Cons frames the story through the lens of an unhealed national wound — a family still without answers, a body still missing, and a justice system that produced convictions without closure. The production incorporates reporting, archival material, and contextual analysis of the investigative gaps that have dogged the case since 2009.

Reception

Upon its release on 5 November 2021, Where Is Marta? immediately reached the top spot on Netflix in Spain, reflecting the deep and undiminished public interest in the del Castillo case more than a decade after Marta's disappearance. The case's combination of conflicting confessions, alleged cover-up, multiple defendants, and the haunting absence of a body made the documentary a natural flashpoint for audience engagement.

Critical reception highlighted both the strength of the subject matter and the unresolved nature of the story. A review on Heaven of Horror noted that the case remains without a final resolution — that despite convictions, the central question of where Marta's body is has never been answered, meaning the documentary itself can offer no conclusive ending. This ambiguity was seen by some reviewers as a limitation, but by others as an honest representation of the case's true status.

The series was also praised for being the first documentary production to examine the case with this level of depth and structure, revisiting investigative gaps and giving renewed attention to the inconsistencies in Carcaño's confessions and the conduct of the broader proceedings. Its IMDb rating is listed under title ID tt15796898 but was not confirmed in verified sources at the time of publication.

The Case Today

As of the documentary's release in late 2021 and beyond, the Marta del Castillo case remains one of Spain's most significant unresolved true-crime stories. The core tragedy has not changed: Marta's body has never been found, and no definitive account of where her remains lie has ever been verified. Miguel Carcaño's multiple and contradictory statements over the years have led investigators and Marta's family on a series of fruitless searches.

Her family has continued to speak publicly about the case, demanding that Carcaño or others with knowledge of Marta's whereabouts come forward. The Spanish public's emotional investment in the case has not waned, as evidenced by the documentary's immediate chart success upon release. The combination of a murder conviction without a body, a cover-up conviction, acquittals for other defendants, and an ongoing absence of remains means the case occupies a uniquely painful place in Spain's national memory — a story where the judicial process has run its course but the truth has not yet been fully told.
