A woman who has been nicknamed the Black Widow due to the deaths of her lovers and spouses has admitted poisoning her fourth husband - only to then backtrack.
Chisako Kakehi is on trail for the murders of three men and the attempted murder of another in Japan. It is claimed all the murders were carried out so she could claim on insurance.
The prosecution believes the woman used cyanide to kill the men and then gained 1 billion yen (£6.87 million) over the course of 10 years. But she is said to have lost most of the money by financial trading.
The 70-year-old admitted poisoning her fourth husband, Isao, in 2013 at her trial which started this week, according to Channel News Asia.
The Asahi newspaper claimed she said: "I was waiting for the right timing as I wanted to kill him out of deep hatred."
According to reports Kakehi used dating agencies to meet men, where she said any suitors should be wealthy and childless.
Yet on Wednesday (July 12), according to Mainichi Daily, she peeformed a u-turn in court, saying: "I don't remember [what I said]."
Her lawyers have argued their client is not guilty of murdering Isao Kakehi on diminished responsibility grounds.
Last year Kyoto District Court said that according to medical records the woman has early stage dementia, but despite this was ruled fit to stand trial.
If Kakehi is convicted of murder she could face the death penalty, but she reportedly claimed "I'd be happy to die if you give me a drug now."
The criminal justice system has also been criticised as post-mortems were not carried out on the bodies as the deaths were not treated as suspicious.
The final hearing is scheduled for October and the verdict is expected to be passed the previous month.
