One of the trending series this week on Netflix is the documentary “The Yara Gambirasio Case: Beyond Reasonable Doubt,” which, according to FlixPatrol, has reached the global ninth spot on the most streamed list.

In five episodes, the series tells the story of the disapparition of Yara Gambirasio, when she was 13 years old in 2010. She was coming home from gymnastics, and months later, her remains were found in a nearby field in Brembate di Sopra, Lombardy, Italy.

After the investigation found unknown DNA on her remains, it all pointed out to one man: Massimo Bossetti. But was the highly publicized investigation as flawless as it seemed? Here’s what to know about the series and the real life case.

Who is behind ‘The Yara Gambirasio Case: Beyond Reasonable Doubt’?

The docuseries was developed and directed by Gianluca Neri. It was also written by Carlo G. Gabardini, Gianluca Neri, and Elena Grillone.

What happened to Yara Gamirasio?

The docuseries tells the story of the case of Yara Gambirasio, a 13-year-old from Brembate di Sopra, who vanished on November 26, 2010. That evening, she was last spotted about half a mile from her home at the gym where she practiced rhythmic gymnastics.

After three months of intensive searches and significant media coverage, Gambirasio’s body was discovered in a nearby field. Investigators found unfamiliar DNA on her remains, prompting the largest DNA sweep in the country’s history.

Their efforts eventually led them to Massimo Bossetti, a construction worker and father of three. However, as there were some controversies regarding the DNA samples, the documentary raises some questions about the investigation led by prosecutor Letizia Ruggeri.

Was Bosetti really guilty?

Netflix‘s documentary explores whether the investigation resulted in the correct conviction, partly focusing on Bossetti’s defense during the trial. Bossetti insisted on his innocence, claiming that someone had stolen his work tools, including a knife that could have been used in the murder. He also contended that the DNA evidence was either fabricated or cross-contaminated, which the police refuted.

Additionally, he raised suspicions about a gym employee who never explained why she was crying on the night of Gambirasio’s disappearance or why she deleted some texts immediately afterward. Despite these defenses, Bossetti was found guilty and sentenced to life imprisonment on July 1, 2016. His conviction was upheld after two appeals.
