A MUM is accused of killing her twin daughters after telling a therapist that she had “perverse ideas” about the six-year-olds.
Gisele Beatriz Dias, 44, allegedly suffocated Manuela, 6, before attacking her second daughter Antonia, 6, eight days later in Brazil.
Manuela was discovered unconscious with her mum in their family home in Igrejinha on October 7, 2024.
Eight days later, her twin sister Antonio was also found dead in her bed.
Mum Gisele Beatriz Dias was arrested following the second death.
The girls’ devastated father Michel Persival Pereira described returning home from work to discover his daughters dead.
He said: “I went out to work, I came back, had a dead daughter.
“I went out to the supermarket, I came back and had another daughter dead.”
After finding Manuela, Michel scooped her up and raced to the hospital.
He said: “I took her on my lap, ran to the hospital, shouted, I yelled, I prayed to God.”
But when his second daughter Antonia died he lost hope in saving her.
“When the paramedic said she was dead, I sat down and stayed there. I had no more strength.”
Police initially believed the girls had been poisoned – but no trace of toxins were found in their blood.
Forensics tested more than 100 substances including arsenic and pesticides – but none were present in the bodies of Manuela and Antonia.
Autopsies into their deaths remained inconclusive – but prosecutors allege that the pair were suffocated by their mother.
Fresh suspicion fell on Dias after a doctor who treated her for severe depression testified that she had spoken of having “perverse ideas” about her kids.
Her eldest daughter also told investigators she believed her mother was “fully capable” of killing the twins.
Dias had been due to stand trial in July 2025 – but the proceedings were delayed after her lawyers demanded a mental health assessment.
A psychiatrist has now concluded that Dias did not have a metal disorder that would prevent her from knowing that what she did was a crime.
The twins’ aunt Graziela Pereira said the results gave the family some relief after “the two most challenging years of our lives”.
She said: “In the same way that the girls had no choice at that moment, whoever did this to them will not have the choice either, because now she will go before a jury.”
Dias has always denied killing her own daughters and her defence intends to argue her innocence before a jury.
