Technical details and legal reactions regarding the defendant’s sanity

The result of the psychiatric evaluation was received by the family’s lawyers as a fundamental validation for the continuation of the severe procedural rite. The report indicates that, on June 12, 2024, the attacker had full insight into the attack carried out at the family residence, on Barueri.

The lawyer representing the girl’s father publicly stated that the technical document contains attempts to mitigate criminal responsibility by the accused’s defense. Para the legal sector, the clarity of the report allows justice to focus on the seriousness of the feminicide and the aggravating factors of the cruel means used against the minor.

Confession reveals detailed dynamics of the crime in Jardim Tupã

The accused detailed in his official statement that he returned from a trip to the coast of São Paulo on the morning of the crime, aware that the residence would be vulnerable. Ele reported that he entered the property at around 10am local time, taking advantage of the fact that the door was just closed, and found the child lying on a bunk bed.

During the interrogation, the man stated that he questioned his stepdaughter about her mother’s personal life, which allegedly started a brief argument. Ele told authorities that he “lost his mind” after being insulted by the child and looked for a knife in the kitchen to carry out the fatal attack.

According to the confessed defendant’s account, he believed that the first blow would have been lethal, but he continued the attack without offering logical explanations for the sequence of stab wounds. The expertise now released contradicts any hypothesis of an uncontrollable psychotic break, maintaining the focus on the individual’s deliberate conduct.

Post-crime behavior and attempts to conceal evidence

After the murder, the attacker demonstrated coldness by leaving the residence and returning minutes later to look for a forgotten cell phone at the scene. Câmeras monitoring equipment recorded the moment he was going through trash cans in the region, allegedly discarding objects related to the crime committed shortly before.

The man went to his workplace at a furniture store, where he changed his clothes so as not to raise immediate suspicion. Ele admitted to having thrown away the shoes used during the action, although he preserved the shoe laces for reasons that he was unable to explain during the statements collected by Polícia Civil.

• The offender worked normally after the crime in Barueri.
• Clothes were changed to hide traces of blood.
• The murder weapon was discarded in a nearby public dumpster.
• The cell phone was recovered by the defendant before his initial escape.

The police investigation managed to gather material evidence that corroborates the accused’s coldness after the act, including security images and witness statements. Essas information, added to the health report, forms the basis of the prosecution’s strategy for the conviction of qualified homicide.

History of instability and insecurity in family relationships

The defendant told investigators that he had trauma from previous relationships, marked by cases of infidelity that led him to seek religious help in the past. Ele alleged that his partner, Larissa’s mother, knew his history of emotional instability and previous suicide attempts, but that living with her children was considered satisfactory.

Despite claiming that he was not feeling well emotionally in the days leading up to the crime, the expert report was categorical in stating that such feelings did not constitute mental alienation. The aggressor reported that he had been charged by his partner with greater professional and financial responsibility, which left him thinking before deciding to return home in Barueri on June 12th.

Victim was found alone after school hours

Larissa The child should have attended school in the afternoon, but remained at the property since the mother left, which occurred at 6 am to complete her work day.

The residence, located in the Jardim Tupã neighborhood, had a gate that was not locked, facilitating Diego Antônio Sanches Magalhães’s entry without the use of brute force. The scenario found by the authorities indicated that there was no intense physical struggle, reinforcing the theory that the victim was surprised while resting in his room.

Legal proceedings and request for compensation for the family

Ministério Público of São Paulo has already requested compensation of R$ 100 thousand to be paid by the attacker to the victim’s family as compensation for moral damages. Além of financial compensation, the defendant is responsible for femicide committed with cruel means, aggravated by the fact that the victim was a minor and was under his indirect care in the domestic environment.

The process now awaits the scheduling of instruction and trial hearings, where the mental health report will be a central piece to rule out any claim of non-imputability. The prison system keeps the accused isolated for security reasons, given the nature of the crime that generated great repercussion in the metropolitan region of São Paulo.

Polícia Civil concluded the collection of testimonies from neighbors and family members, consolidating the investigation that points to the stepfather’s premeditation and coldness throughout the process. With mental illness ruled out, the legal expectation is that the defendant will face the popular jury based strictly on the facts narrated and the technical evidence collected by Instituto, Medicina Social and Criminologia.

The necroscopic analysis previously carried out by Instituto Médico Legal had already detailed the severity of the injuries to the girl’s neck and chest, confirming the brutality of the attack. Agora, with the validation of the author’s mental capacity, the case enters its decisive phase for the application of Brazilian criminal law.
