A Brazilian woman who was married to the then-Greek Ambassador Kyriakos Amiridis to her country was sentenced to 31 years in prison for planning his murder with her lover.

The BBC said Françoise de Souza Oliveira had been having an affair with a military police officer, Sergio Gomes who confessed to killing the ambassador and was jailed for 22 years.

In 2016, Kyriakos Amiridis’ charred remains were found in the boot of a burnt-out car in Rio de Janeiro but it took five years for her to be brought to trial where the judge called the crime “bestial” the report added.

Another man, Eduardo Moreira Tedeschi di Melo – a relative of Gomes – was acquitted of murder and served a year in jail for helping to hide the body. Amiridis was 59 and had been consul in Rio de Janeiro from 2001-04, and returned to Brazil as ambassador the year he was killed. He married Françoise in 2004 and the couple have a daughter.

Before his death, Amiridis had traveled from the capital, Brasilia, to the city of Nova Iguacu, north of Rio, to spend the Christmas holidays with his wife and her parents, the report added.

The victim's wife reported him missing and told police that he’d left their apartment  without explanation and driven off in a rental car, which was spotted the next day from an air search.

Investigators found blood stains on a sofa in the apartment where the couple had been staying, and it’s believed he was killed there before his body was taken away, the story said.

She had denied any role in the plot and later said she couldn't keep her lover from killing her husband and that also wasn't there when it happened, but police then said the "evidence clearly puts the Ambassador's wife as a co-author of the crime."
