A woman referred to as a “black widow” after allegedly killing two of her friends with rat poison was sentenced to 21 years in prison.

Wane Brenda Oliveira was found guilty of the grave homicide of one of the dead yesterday in Itabuna, northeastern Brazil.

In 2017, she is said to have given her two friends “Chumbinho” – a rat poison made with the carbamate insecticide aldicarb – eight months apart.

High amounts of aldicarb can kill people by paralyzing the airways.

The poison is illegal in many countries like Germany and Switzerland, but it can be bought in three Brazilian states – including the one where Oliveira lives.

She was accused of killing her friends who were living with her at the time when she reportedly found out they were planning to drop her.

Edvaldo Araujo Alves, 40, died in April 2017.

His death at the time was attributed to a massive heart attack.

Months later, she began dating Evandro Bonfim de Souza, also 40, whom she allegedly later poisoned to death.

In both cases, the defendant took her victims to an infirmary after the poison took effect – where both unfortunately died.

Oliveira’s version of events had never satisfied Edvaldo’s family members, who had said he was dissatisfied with their relationship.

His body was exhumed a year later after the poisoning was suspected, leading coroners to confirm his relative’s suspicions.

Oliveira stands because of the death of Evandro Bonfim. in court



Oliveira was sentenced to 21 years in prison for the first murder, and a trial date has not yet been set for the second murder.

The defendant has been in custody for four years.

During the trial, her legal defense denied the allegations made against her and appealed the court’s decision.
