There is blood on his clothes and powder residue on his hands.

the lead investigator, Mariana Enriquez (Valentina Muhr)and her partner Bruno Duran (Mario Horton) have difficulty believing that someone with Down syndrome was capable of such a violent act. Especially since everyone who knows the young man describes him as a kind and gentle soul. Tomy was a beloved member of a foundation for people with Down Syndrome. His girlfriend, Cristina (Pia Urrutia), is the daughter of the foundation owner, Sofia (Claudia Di Girolamo).

Tommy’s brother Guillermo “Got” Ruiz (Gastón Salgado)He has a criminal past and appears to be the most likely shooter. But why should he leave his beloved brother to take the fall?

The finale shows the aftermath of Bekam’s death. Tomy is understandably heartbroken, as is Mariana, who is beginning to suspect Bruno’s corruption. She wants to continue her investigation, but her boss orders her to drop the case. Things are not looking good for Tomy as the judge wants him to go to jail and if he tried to escape he would likely get an even longer sentence.

Is Cristina moving to Spain?

Cristina is also upset that Tomy is back in police custody. Locking herself in her room and refusing to speak to her family leads Sofia to propose a rather drastic measure; She asks her husband for a job transfer across the Atlantic to Spain so that they can finally free their daughter from Tomy and the whole murder drama.

Mariana doesn’t give up on Tomy

Despite receiving a clear command, Mariana is not willing to give up saving Tomy. She calls his public defender and tells him about Zavala’s presence at the crime scene the night of the murder and the tampered evidence. After the attorney confirms the details with Tomy, he asks to see Mariana so they can better plan his defense.

Meanwhile, Mariana tricks Bruno into leaving her alone in his car, giving her enough time to place another recording device. She then interviews the mule who was supposed to help Bemm cross the border, who confirms that someone threatened him and told him not to go to the meeting point. Eventually, Mariana visits Zavala to let him know that she’s after him. While Mariana is there, the factory owner calls his lawyer and clarifies that he has no interest in speaking to her.

The next day, when Mariana tries to tell her boss about the mule’s confession, he suspends her. Her suspension didn’t last long when her recorder caught Bruno incriminating himself and the police chief as Zavala’s associates, leading to the arrest of the three men.
