Netflix have long been known for their sheer volume of true crime documentaries but taking a spin on the format with a fictional limited series, the streamer has now released The Asunta Case.

The six-parter is a miniseries based on true events, dramatically outlining the case of 12-year-old Asunta Basterra, who was reported missing by her parents in September 2013 and whose body was found hours later next to a road outside Santiago de Compostela.

The Spanish case gripped the nation when it unfolded across many years as the investigation turned the focus onto Asunta’s adopted parents, Rosario Porto and Alfonso Basterra, a wealthy couple who adopted Asunta (born Fang Yong) at nine months old from the Hunan province in China.

Now, because of the new Netflix production, many more people will come to learn about the shocking case and will, naturally, have questions about the true story at the centre of it. Read on for everything you need to know about the story behind The Asunta Case.

On the night of Saturday 21st September 2013, Rosario Porto and Alfonso Basterra reported the disappearance of their daughter Asunta. The parents, who divorced in 2013, shared responsibilities of caring for Asunta. On that night in question, Porto had told police that Asunta was at her apartment doing homework and Porto had left her there as she went to the family’s country home in Teo parish.

When Porto returned home at 9:30pm, there was no sign of Asunta. Not being the kind of child to run away, Porto had called Basterra to see if their daughter had just gone to visit him, then the pair called some of Asunta’s friends to see if they had heard from her.

Reporting the disappearance to the police, Porto and Basterra were informed just a few hours later that Asunta’s body had been found next to a road outside Santiago de Compostela.

After days of interviews and a wake for Asunta, Porto was arrested at the funeral on 24th September after police had recovered CCTV footage that didn’t match up with Porto’s story of the night of Asunta’s disappearance.

The petrol station footage revealed that both Porto and Asunta were on their way to Teo at 6:20pm and after being confronted with the new timeline of events, Porto changed her story to explain that Asunta had accompanied her to the country home. She then said she took Asunta back to Santiago to do her homework and went out to a store, realised she left her purse in Teo and drove back to retrieve it.

After examining the CCTV footage of the surrounding areas and roads Porto claimed to have taken in this journey, the police found no evidence of her car and were led to believe that the mother and daughter had arrived in Teo around 6pm, but that Porto had left at 9pm.
