The Civil Guard Ríos decides to visit the mother's country house and there he discovers in a trash can some orange ropes like the ones found next to the corpse.

The people in charge of the case have breakfast after a long night and the investigating judge gives an irrelevant piece of information to a journalist.

A security camera footage from a gas station shows that Rosario had not left the girl at home as she had told police.

In the cells, Rosario suffers an anxiety attack and is taken to the terrace to get some fresh air, where she opens up to the Civil Guard and talks about her lover Vicente.

Back in the present day, Rosario and Alfonso's apartments are searched, neighbors and strangers crowd the street to rebuke and threaten them.

Traces of DNA found on the T-shirt worn by Asunta point to Carlos Murillo, a Guatemalan living in Madrid, but he has a solid alibi and it all seems to be due to an inexplicable error by the central laboratory of the Guardia Civil.

5 "24 hours" Agent Ríos verifies that a woman can drag a sack of Asunta's weight and goes before the judge to tell him his interpretation of the facts: Rosario returned to her lover, argued with Alfonso, who told him that she could never get rid of him because she needed him to take care of Asunta; Rosario prepares an overdose of lorazepam and dissolves it in orange juice but gives it to Asunta when she asks for something to drink; she takes her to the cottage, drowns her with a cushion, and then leaves the corpse on a dark track; when she talks to Alfonso and tells him that the girl is gone, Alfonso decides to help her pretend that it wasn't her.

The judge responds with his own interpretation: Alfonso has discovered some secret that could sink them and decides to kill Asunta; Rosario can't object.

When Asunta is taken to the scene of the crime, Alfonso crouches in the back of the car so as not to be seen by any cameras; Between the two of them, they squeeze the cushion over the girl's face.

Rosario looks up from the magazine she's reading and smiles The series is a Bambú Producciones production created by Ramón Campos, Gema R. Neira, Jon de la Cuesta, and David Orea Arribas.

Candela Peña had been called to play the role of an agent, but she asked to audition as Rosario Porto and managed to convince the producers.

Those people who provided new testimonies and a lot of information did not want to appear on camera and that led him to propose a fictionalized series.

[5] Raquel Hernández Luján of HobbyConsolas rated The Asunta Case with 80 points ('very good'), highlighting the chilling performance delivered by Candela Peña as the best thing about the series.

[15] Álvaro De Luna of Esquire cited the cast performances as the truly remarkable thing about the series, including Peña, Ulloa, Gutiérrez and Borrachero's.

[16] Álvaro Onieva of Fotogramas rated the series 7 out of 10 points, deeming it to be "well-produced, directed and acted fiction, [as well as] formally sober and well-paced", but also wondering if the true crime "justifies its existence" bringing something to the table other than a commercial justification.
