Who was Anabel Segura?

At 22 years old, Anabel Segura had her whole life ahead of her.

She lived in La Moraleja, a wealthy area in the residential district of Alcobendas municipality in northern Madrid.

Anabel was studying business at the private ICADE university in Madrid.

She was the eldest daughter of Spanish businessman José Segura Nájera, who set up his petrochemical company in Germany, where he met Anabel's mother, Sigrid Foles, before the family moved to Spain.

What happened to Anabel Segura?

On April 12, 1993, Anabel went on a run in her neighbourhood. It was something she had done several times before. She donned her tracksuit and grabbed her Walkman music player and set off. But this time, she never made it home.

As she headed out, Muñoz Guadix and Ortiz Aon pulled into the neighbourhood with a plan in mind. The friends wanted to orchestrate a kidnap for ransom in the wealthy suburb, and Anabel became their unlucky target.

The friends got out of a white van and held Anabel at knifepoint, demanding she get in.

But she didn't go without a fight. Her tracksuit and Walkman were lost in the struggle and found at the scene of the kidnapping.

The only eyewitness was a local school gardener who couldn't make out the license plate number, but he immediately called police.

Muñoz Guadix and Ortiz Aon drove around looking for somewhere to hold Anabel hostage, giving Anabel the time to try to escape. But her attempt was foiled and her kidnappers recaptured her.

They took her to an abandoned brick factory in Numancia de la Sagra in Toledo, where they strangled her and buried her nearby.

Anabel's disappearance was just the beginning of her family's nightmare.

Her kidnappers went on to pretend she was alive for almost three years to extort money from her devastated loved ones.

Anabel Segura Netflix documentary: 900 Days Without Anabel.

The new Netflix docuseries, 900 Days Without Anabel, features never-before-heard tapes by the police as they tried to negotiate with her kidnappers.

Over the 900 days, her kidnappers made 14 ransom demands for her parents.

On April 14, 1993, Muñoz Guadix and Ortiz Aon demanded 150 million pesetas ($1.46 million).

In the initial call, per the translation in 900 Days, the kidnappers told family friend Rafael Escuredo Rodríguez: "Tell him we kidnapped his daughter but she's doing fine. She doesn't need anything but her safety depends on you — on all of you."

"If you don't do like we say, or if we find out that you've warned the police, she's going to suffer," they said.

It was the start of a traumatic ordeal.

Muñoz Guadix and Ortiz Aon kept Anabel's family on a hook. In July, they sent the family a recording of "Anabel" asking her parents to save her. But in reality it was Muñoz Guadix's wife, Felisa Garcia, pretending to be Anabel in a cruel act.

According to 900 Days, Muñoz Guadix was under financial hardship after buying a house in Pantoja and that's what prompted him to suggest the kidnapping plot in a wealthy suburb.

Desperate to find his daughter, José remortgaged his home and offered to pay millions to whoever could find Anabel, according to the docuseries. He even went as far as hiring private investigators to track down leads.

Her parents borrowed money from friends, family and even acquaintances to meet the ransom. On two occasions, representatives for Anabel's families arranged to meet the kidnappers to pay the ransom but the criminals never showed up.

Anabel's disappearance shocked Spain, with community members taking to the streets to demand her release.

The suspense continued for 900 days until her body was found in September 1995.

Where are Anabel Segura's kidnappers now?

In the end, it was a local Toleda resident that recognised Ortiz Aon's voice on the ransom recordings played on the news. From here, everything slotted into place.

He called police and on September 28, 1995, Muñoz Guadix and Ortiz Aon were arrested. The pair confessed and said they had only wanted to receive a reward, not kill Anabel.

In September 1995, Emilio Muñoz Guadix and Candido Ortiz Aon were arrested and sentenced to 39 years behind bars, later increased to 43.

Garcia was also arrested for pretending to be Anabel on the tape. She was sentenced to six months imprisonment.

Ortiz Aon died in jail in 2009. Meanwhile, Muñoz Guadix was released after 18 years in 2013.

Upon his release, Muñoz Guadix described his motivation as "purely economic".

"I made a serious mistake, which I accepted from the first moment, unlike others, and that's it," he told laSexta.

"I am sorry, I am very sorry for what happened, I already said it in court, I would give ten years of my life so that this would not have happened."
