The "Black Widow" is awaiting execution.. a Japanese woman poisoned 4 men in order to inherit them

The old Japanese woman, Shisaku Kakei, who killed three of her accomplices and tried to kill the fourth, is still awaiting the death penalty after losing her last chance to appeal to the courts.

According to CNN, Kakhi, who is currently 74, was convicted of killing three men with a poisonous substance, while the fourth escaped death.

The Osaka High Court had upheld the death sentence for Kakei, who became known as the "Black Widow", after she used cyanide poison to kill her wealthy, elderly romantic partners in order to inherit them and receive life insurance money.

In his ruling last June, the judge said: "She used a marriage agency to identify elderly victims to poison them one by one after making them trust her. It is a relentless crime based on clear and strong killing intent."

The serial killer was able to raise about 1 billion Japanese yen (about 8.8 million US dollars) in 10 years, but later lost most of that fortune to speculation in the financial markets.

Little is known about the woman who has become notorious in Japan. She was born in the southwestern Saga Prefecture and worked in a print shop before marrying her first husband in 1969 when she was 23.

Despite her defense team's attempt to prove that their client suffers from Alzheimer's dementia, the court rejected these arguments and upheld her death sentence.
