Nora Dalmasso DNA Match: 5 Shocking New Updates That Could Finally Solve Argentina's Coldest Case

The nearly two-decade-long mystery surrounding the 2006 murder of Nora Dalmasso, a prominent socialite from Río Cuarto, Córdoba, has taken a dramatic and unexpected turn in late 2024 and early 2025. After years of legal battles, public scrutiny, and a famous Netflix documentary, a new DNA match has emerged, pointing the finger at a previously overlooked individual and seemingly exonerating the victim's immediate family once and for all. This critical piece of forensic evidence has reignited the pursuit of justice, offering a fresh path to solving one of Argentina's most notorious and complex cold cases.

The latest developments center entirely on the organic traces collected from the crime scene, specifically a DNA profile that did not belong to Nora Dalmasso's husband, Marcelo Macarrón, or her son, Facundo Macarrón. The revelation of the new suspect, Roberto Bárzola, based on this long-held genetic evidence, marks the most significant breakthrough since the murder occurred, providing the Dalmasso family with renewed hope for a final resolution nearly 19 years after the tragic event.

• Full Name: Nora Raquel Dalmasso.
• Date of Birth: January 17, 1955.
• Age at Death: 51 years old.
• Place of Residence: Villa Golf neighborhood, Río Cuarto, Córdoba, Argentina.
• Spouse: Marcelo Macarrón, a successful physician and trauma specialist.
• Children: Facundo Macarrón (son) and Valentina Macarrón (daughter).
• Date of Murder: November 26, 2006.
• Cause of Death: Found strangled with a bathrobe belt in her daughter's bedroom. She was found wearing only a Rolex watch.
• Circumstances of Death: Her husband, Marcelo Macarrón, was away at a golf tournament in Punta del Este, Uruguay, at the time of the murder. Her son, Facundo, was studying law in Córdoba City.

The shocking nature of the crime—a violent sexual assault and murder in an upscale, seemingly secure neighborhood—immediately launched a massive investigation. However, the initial handling of the crime scene and the subsequent investigative missteps led to years of speculation, misdirection, and a revolving door of suspects, turning the case into a national spectacle and a symbol of Argentina's flawed justice system.

The DNA Match That Broke the Case: Roberto Bárzola

The core of the "Nora Dalmasso DNA match" story lies in the persistent re-analysis of forensic evidence. For years, the investigation was plagued by the inability to conclusively match the genetic material found at the scene to any of the primary suspects.

The Exoneration of the Macarrón Family

Early in the investigation, suspicion fell heavily on Nora's immediate family. Her son, Facundo Macarrón, a law student at the time, was charged in 2007 with "homicide and aggravated sexual abuse." Later, the focus shifted to her husband, Marcelo Macarrón, who was charged with "qualified homicide" but was later acquitted in 2022 after a trial by jury. The new DNA evidence, which became the cornerstone of the most recent investigation, proved that the genetic profile found on the victim's bathrobe belt and hair samples did not belong to either Marcelo or Facundo, definitively clearing them of involvement in the murder.

The Identification of Roberto Bárzola

The true breakthrough occurred in late 2024 and was widely reported in early 2025. Investigators, through a renewed focus on the organic traces, identified a new suspect: Roberto Marcos Bárzola. Bárzola, a native of Río Cuarto, was identified as a 45-year-old man who worked in the area as a floor polisher and gardener. The evidence against him is significant:

• Key Evidence: His DNA profile was found to match the genetic material collected from the robe belt used to strangle Nora Dalmasso and from hair samples found on the victim.
• Connection to the Victim: Bárzola was known to have been working in the Dalmasso residence, polishing the wooden floors, in the days immediately preceding the murder in November 2006. This established a clear physical link to the property.
• Legal Status: As of mid-2025, Roberto Bárzola has been officially named as a suspect and the alleged perpetrator of the crime, with the Argentine justice system moving to formalize charges based on the DNA match.

This shocking development has shifted the entire narrative of the case, moving the focus away from the family's internal dynamics and toward a possible crime committed by someone with access to the home. The reinvestigation, nearly two decades later, utilized modern forensic science to finally provide a credible suspect.

The Long Road to Justice: Exoneration and Ongoing Appeals

The "Nora Dalmasso DNA match" is not just a forensic victory; it represents a major turning point for the Argentine justice system and the Macarrón family. The case's high profile has been maintained through continuous media coverage, a popular Netflix documentary titled The Many Deaths of Nora Dalmasso, and the family's persistent legal efforts.

The new suspect also sheds light on the initial investigative failures, where the focus on a "crime of passion" within the family may have allowed the true perpetrator to remain free for so many years. The family continues to pursue legal actions, including an appeal against the previous court decision regarding the "sole accused," demonstrating their commitment to seeing a final, conclusive verdict.
