Woman Poisoned Boyfriend To Death With Rat Poison After Discovering That He Want to Leave Her
Wane Brenda Oliveira used chumbinho, an illegal rat poison that can paralyse the respiratory system. She allegedly did the same to another boyfriend months later
A woman dubbed the “Black Widow” killed her boyfriend with rat poison – and is suspected of doing the same to another partner.
Wane Brenda Oliveira, 34, killed Edvaldo Araujo Alves on April 16, 2017, in the north-eastern Brazilian state of Bahia.
The pair had been living together for a year, and Oliveira concocted the plan after discovering he wanted to break up with her.
She took Mr Alves to a healthcare unit after the poison took effect, where he was pronounced dead.
Edvaldo’s death at the time was attributed to a massive heart attack.
He was buried, but his body was exhumed a year later after the poisoning was suspected, with coroners confirming the cause of death.
The defendant’s version of events had never satisfied Edvaldo’s family members, who had said he was unhappy with the relationship.
Months after Edvaldo’s death, the defendant was in a new relationship with Evandro Bonfim de Souza, also aged 40, whom she allegedly also later poisoned to death after discovering he wanted to leave her.
She allegedly used “chumbinho” – an illegal rat poison made with the carbamate insecticide Aldicarb.
High amounts of Aldicarb can kill humans by paralysing the respiratory system.
Despite being banned in several countries, such as Germany and Switzerland, the product is possible to purchase in three Brazilian states, including Bahia.
Oliveira was guilty of aggravated homicide in the Courthouse of Itabuna in the north-eastern Brazilian state of Bahia on Tuesday, 31st August.
The defendant, who has been in preventive custody for four years, is awaiting sentencing for the second alleged killing.
The defendant was sentenced to 21 years in prison for the first murder, and a date has not yet been set for the trial for the second alleged murder.
The defendant has been in preventive custody for four years.
During the trial, her legal defence denied the charges against her and has appealed the court’s decision.
