The crime involved the murder of two young children and the near-fatal attack on their older sister, Erika Peña.

Diego’s relationship with Erika was marred by jealousy and frequent arguments, leading to a troubled dynamic. Eventually, Erika ended the relationship due to Diego’s jealousy and controlling behavior, including stealing her cell phone.

Around 10 AM, the secretary, Linda, finds Erika severely injured and calls the police, who then discover the bodies of the two youngest children. Erika falls into a coma, and the police investigation begins with few initial clues. They hoped Erika would provide information upon recovery. Investigators find a cigarette butt linking Diego Santoy, Erika’s ex-boyfriend, to the scene, although its relevance is initially questioned. The children’s bodies are quickly cremated, and the house is remodeled.

In this part of the video, the discussion focuses on the controversial aspects of a confrontation involving Diego and Erika, where Diego claims he wanted to give Erika a knife, which she denies. The validity of this scene is questionable due to possible editing. Diego’s manner towards Erika was affectionate, while she was hostile. Diego also had a conflicting point with Linda, Teresa Coss’s secretary, over his relationship with the children, which Linda contested due to her limited interactions with him.
Further, the video elaborates on the media’s polarized portrayal of the case, with some outlets favoring Erika’s version and others supporting Diego, leading to public support for Diego including fan clubs. Psychologists commented on Diego’s charm and the influence of his appearance and background on public perception.

Experts labeled Diego with an antisocial personality disorder, although his confrontation with Erika showed mixed expressions of regret. Diego’s trial spanned over four years, during which public support and opposition remained strong. Erika was not accused, being deemed another victim. Speculation surrounds the death of Diego’s lawyer, with theories suggesting her death might be linked to her involvement in the case.
00:40:00
In this segment, the video discusses multiple theories and developments surrounding Diego Santoy’s case. One theory posits that Santoy’s lawyer, known for handling drug trafficker cases, might have been targeted due to these associations rather than his involvement in the Cumbres murder. Other details include leaked prisoner statements about threats to Santoy’s life, accusations against the Peña Cos family, and Diego’s engagement and marriage in prison. The timeline covers Santoy’s trial and sentencing to a cumulative 138.5 years, which was later reduced to 71 years, and then capped at a maximum of 40 years per Mexican law. The segment also touches on the attempted reopening of the case in 2020 for new confrontations between Diego and Erika, which were stalled by the pandemic. Furthermore, it details the lives of key figures post-trial, reporting on Erika’s marriage, Santoy’s prison activities, and other pivotal family events, including the mysterious death of Erika’s father and the eventual destruction of the crime scene house.

In this segment, the speaker explores several theories regarding a complex situation involving multiple family members. One theory suggests Diego harmed his younger siblings to get back at Erika and planned to kill her and himself. It’s mentioned that Diego spread a rumor about having a relationship with Erika’s mother, which was intended to cast doubt. Erika’s sister, Asura, claimed she was unaware of the events, but some believe she was complicit if Erika was involved. A different theory implicates the parents in satanic rituals, allegedly using Diego to commit the crime. This theory has the least support. Linda, Teresa’s secretary, is also questioned, with doubts about her claim of not hearing anything due to her office’s location. Another theory examines the children’s paternity, suggesting they were the result of Teresa’s affair with Fernando Elizondo. Finally, there’s a theory that both Diego and Erika were partly truthful and guilty, complicating the narrative further.
