“EIGHT DAYS APART”: NEW DEVELOPMENT IN THE CASE OF SIX-YEAR-OLD TWINS MANUELA AND ANTONIA

A father lost both of his six-year-old daughters just eight days apart. Now, a newly completed psychiatric assessment has brought the case against their mother closer to its next stage in court.

The deaths of twin sisters Manuela and Antonia Pereira shocked the community of Igrejinha in southern Brazil in October 2024. Two years later, their family is still waiting for answers.

Their mother, 44-year-old Gisele Beatriz Dias, is accused of causing the girls’ deaths. Prosecutors allege that both children were suffocated, but the case has not yet been decided by a jury. Dias denies the allegations, and her defence says it intends to demonstrate her innocence at trial.

TWO LITTLE GIRLS, EIGHT DAYS APART

Manuela was found unconscious at home on October 7, 2024, and taken to hospital, where she was pronounced dead.

Eight days later, on October 15, her twin sister Antonia was also found unresponsive in her bed. Emergency responders confirmed her death at the family home.

Their father, Michel Persival Pereira, described the devastating experience of returning home and discovering that he had lost both daughters.

“I went out to work, I came back, had a dead daughter,” he recalled. “I went out to the supermarket, I came back and had another daughter dead.”

His words capture the unimaginable grief of a parent facing two losses in such a short period.

INVESTIGATORS STRUGGLED TO FIND ANSWERS

Initially, investigators considered poisoning as a possible explanation. Forensic specialists reportedly tested more than 100 substances, including pesticides, medications and other chemicals, but found no toxins that explained the deaths.

Autopsies also failed to establish a definitive cause.

Despite the inconclusive forensic findings, prosecutors allege that the twins died through suffocation. That allegation remains to be examined through the judicial process.

Suspicion reportedly intensified after a doctor who had treated Dias for severe depression told investigators that she had spoken about disturbing ideas concerning her daughters. The twins’ older sister also gave evidence to investigators.

These accounts form part of the case, but they do not replace the jury’s responsibility to examine the evidence.

A PSYCHIATRIC REPORT CHANGES THE NEXT STEP

The criminal proceedings had been suspended while Dias underwent a court-ordered psychiatric assessment.

The report, completed in September 2026 and added to the case file in October, concluded that there was no psychiatric evidence showing that a mental disorder had significantly prevented her from understanding the alleged acts were unlawful at the time.

The finding concerns whether she can be held criminally responsible if the allegations are proven. It does not establish that she committed the alleged offences.

The prosecution and defence now have an opportunity to respond to the report. The case is expected to move toward preparation for a jury trial, although no trial date has been announced in the latest reports.

“THE TWO MOST CHALLENGING YEARS OF OUR LIVES”

The twins’ aunt, Graziela Pereira, said the assessment brought the family some relief after what she described as the two most challenging years of their lives.

For their loved ones, the legal process represents a chance for the circumstances surrounding Manuela and Antonia’s deaths to be examined in court.

Dias remains in custody and continues to deny responsibility. The jury will ultimately have to assess the evidence before reaching a verdict.

Two little girls, two deaths separated by just eight days, and a family still waiting for answers: the case remains a painful reminder of the questions that can remain when a tragedy has no clear forensic explanation.
