Prime Video production portrays Elize Matsunaga’s daughter’s shock when discovering crime

The recently released fictional work Tremembé, which arrived in the Prime Video catalog at the end of October 2025, brings to light the consequences of the murder of Marcos Matsunaga, which took place in the capital of São Paulo more than a decade ago. The script sheds light on the couple’s heiress, a baby just one year old at the time of the murder, who ended up being raised by her paternal grandparents, Mitsuo Matsunaga and Misako Kitano. The plot shows how the girl became aware of the family tragedy during an event at school when she was nine years old, raising profound discussions about the mental damage caused to minors indirectly involved in cases of great national repercussion.

One of the chapters details the breaking of ties caused by the arrest of the biological mother, sentenced to almost two decades in the Tremembé Women’s Penitentiary. Structured based on the literary investigations of writer Ulisses Campbell, the television adaptation delves into everyday life behind bars and the silences kept at home to spare the child. Specialists in child mental health warn that breaches of secrecy of this magnitude require immediate psychiatric follow-up to avoid permanent consequences in cognitive development.

• The shock of reality happened in the school courtyard, caused by a direct comment from another student.
• Despite the strong protection scheme set up by family members, the immense media coverage of the trial made the shielding unsustainable.
• Psychological support began shortly after the traumatic episode, aiming to offer emotional coping tools for the minor.

Tremembé’s narrative uses dramaturgical elements to recount this painful passage, combining documentary records and poetic license to encourage debate about the weight carried by the descendants of condemned people.

The episode in the school environment that transformed the girl’s childhood

Amid a celebration aimed at families at the educational institution, a classmate asked who the girl’s real parents were, who promptly pointed to Mitsuo and Misako. This innocent statement generated an immediate response from the other student, who spilled raw information about the murder committed by Elize.

That brief conversation lasting a few minutes was enough to drastically change the child’s perception of the world, pushing him into a reality that had been on the covers of newspapers and magazines across the country for years.

Legal battle tries to erase maternal records from birth certificate

Currently 14 years old, the teenager is the center of a petition filed by the Matsunaga family at the Children and Youth Court of São Paulo, which asks for the definitive exclusion of the mother’s name from her civil documents. The central argument of the action is based on the total absence of emotional and financial support since 2012, a period in which there was no type of face-to-face contact.

Legal guardians argue that this documentary change serves as a shield against social stigmas, ensuring that the young woman has the autonomy to decide on possible contact only upon reaching the age of majority. The process continues under secrecy with constant assessments, putting the teenager’s emotional stability first.

Jurists who follow the criminal scenario remember that there is favorable jurisprudence in this regard, citing heirs of other famous inmates who managed to have their family power removed for similar reasons.

The outcome of this dispute in the courts is expected to end in 2026, pending the conclusion of additional expert reports.

Details of the tragic night that destroyed the Matsunaga family

The crime took place on May 19, 2012, when Elize fired a fatal shot at Marcos Matsunaga inside the apartment where they lived, motivated by fights involving betrayal and alleged physical attacks. The corpse remained in the property for around ten hours, during which time it was dismembered and hidden in luggage, all while the daughter slept in one of the rooms.

The body parts were abandoned in a forested region in Greater São Paulo, and the wife even filed a police report reporting the businessman’s false disappearance. The farce fell apart on May 27th with the location of the remains, culminating in the shooter’s preventive arrest shortly afterwards.

The Jury Court held in 2016 sealed the defendant’s fate with a conviction for double homicide, rejecting the thesis of self-defense presented by the defense lawyers.

The long process of mental recovery after discovering the truth

The therapeutic treatment that began at the age of nine focused intensely on building one’s own identity and developing resilience mechanisms. Professionals involved in the case report a significant evolution, allowing today’s teenager to process the story of her origins without experiencing anxiety attacks.

The domestic environment maintained by grandparents is guided by discipline and affection, with strong encouragement for academic performance and sports to ensure a healthy routine.

Sources close to the family confirm that the young woman treats her legal guardians as father and mother in all everyday situations, leaving the debate about her biological parents restricted to the psychology office.

Elize’s steps outside the prison and the frustrated attempt to contact

Benefiting from the progression to the semi-open regime in 2023 and achieving greater freedom in 2025, the convicted woman began working as an app driver on the streets of São Paulo. She lives in a location monitored by the authorities and is under a restrictive measure that prohibits her from approaching the heiress.

In statements made to the press in the past, the former inmate revealed that she had written a 178-page manuscript, called Picnic in Hell, with the aim of telling her perspective of the events to her daughter.

The text, which supposedly describes a history of domestic abuse suffered during the marriage, was never published or delivered to the recipient.

How the Amazon MGM Studios adaptation portrays the prison system

Led by director Vera Egypt, the five-chapter miniseries transforms the Tremembé Women’s Penitentiary into a central stage where stories of media inmates intersect, including figures such as Suzane von Richthofen. The cast, which includes big names like Ruivarbosa, delivers intense performances in recreating the days following the convictions.

The project financed by Amazon MGM Studios used biographies written by Campbell as a backbone, altering secondary identities and chronologies to ensure the rhythm of the fiction.

Evaluations by specialized critics indicate that the production maintains around 70% historical accuracy, reserving creative licenses for the dialogues and internal conflicts of the cells.

• The first episode focuses on the shock of entering the prison system and the rules of coexistence between prisoners.
• The third chapter delves into group analysis sessions and the weight of family abandonment.
• The fifth and final act shows the transition to parole and the stigma carried by the inmates.

The launch generated a significant volume of searches and comments on digital platforms, reigniting old debates about the effectiveness of the penal system and the limits of resocialization.

The repercussion of the true crime format consolidates the tendency of the audiovisual market to revisit complex police investigations, transforming case files into products of high global consumption.
