The suspect, Dayane Cristina Rodrigues Machado, was arrested in Brazilian city of Sao Goncalo on June 7 following the discovery of her partner, Andre, SunUK reports.
Officers were called to the couple’s house in the neighbourhood of Santa Catarina and found the victim’s lifeless, naked and mutilated body inside.
According to them, his wife had cut off his penis and cooked it in soybean oil in a frying pan, adding that they believe the crime took place at around 4 am after the couple had argued about splitting up.
The officers seized a kitchen knife from the scene believed to be the one she used to kill her husband with and subsequently dismembered him.
Machado, who was arrested, has been charged with murder and corpse desecration.
According to news site UOL, the couple went out to a snack bar on the night of the crime and a row ensued.
However, Machado’s lawyer, Carla Policarpo, said Andre threatened her and she killed him in self-defence.
He added that Machado is remorseful, saying;
He did not accept the end of the relationship and said that if she could not be with him, she could not be with anyone.
However, Andre’s sister, Adriana Santos, says the suspect killed her brother in revenge for him cheating on her.
Relatives have since revealed that the couple constantly fought, and Machado even reported her husband to the police on one occasion.
The couple were believed to have been together for 10 years and had been separated for two years, but still continued to see each other on and off.
They have an eight-year-old son and a five-year-old daughter, and they ran a pizzeria together.
It is not clear if the children were present at the time of the crime but investigation is ongoing.
