Kanae Kijima
, known as The Konkatsu Killer, is Japanese fraudster and serial killer, convicted for poisoning three would-be husbands and suspected of four more, spanning from 2007 to 2009. She was given her nickname for her frequenting of "konkatsu" (marriage-hunting) websites, with her case also being called with similar names (ex. Konkatsu Killings Case, etc.). Exposure. On August 6, 2009, 41-year-old Yoshiyuki Oide, from Tokyo, was discovered dead in his car, parked at a parking lot in Fujimi, Saitama. The cause of death was determined to be carbon monoxide poisoning using a yeontan, but the supposed  suicide had several inconsistencies, because of this an investigation was launched by the Saitama Prefectural Police. As a result of the investigation, they arrived at the doorstep of 34-year-old unemployed woman Kanae Kijima, who was dating Oide. It turned out that she had had several previous lovers, most of whom had died under questionable circumstances. The police determined that Kijima had been fraudulently posing as a bride, and on September 25th, she was arrested for fraud. She had also received 4.5 million yen from a 40-year-old Chiba man, who was living with her at the time  of the arrest. By January 2010, Kijima had been rearrested for seven charges of fraud, while police simultaneously continued carefully investigating the suspicious deaths. On February 22nd, she was indicted for murder. It was for the murder of 53-year-old Takao Terada in Ōme, as recounted by the Tokyo Metropolitan Police Department. However, his death at the time was considered a suicide and was not given an autopsy, resulting in a very unusual murder charge, despite the lack of evidence for the cause of death. Trials. Criminal trial. The first criminal trial was filed in the Saitama District Court , for a consolidated hearing on all cases of prosecution (three murders, six counts of fraud/attempted fraud and one theft). The judicial procedures began on January 5, 2012; the first trial on January 10th; Judgment Day on April 13th, with the lay judge trial lasting 100 days. For the three murder cases, the prosecution provided the following evidence: The prosecution said in a statement: "The night sky is spreading out of the window. When the night breaks, it becomes snow-covered. Even if you don't see when the snow has fallen, you can find that it has fallen in  the middle of the night." Using metaphors, the emphasis on accumulation of circumstantial evidence was sufficient enough to prove Kijima's guilt. On the other hand, Kanae and her defense team claimed that the bribes were voluntarily handed over to her, and their deaths were either accidental or suicide, which warranted an acquittal. The Saitama District Court, with presiding judge Kazuyuki Okuma, acknowledged the prosecutors' accusations, sentencing Kanae Kijima to death. She was the first female defendant to be given such a sentence in a lay judge trial. She appealed on the very same day. Tokyo High Court appeal. The  Tokyo High Court of Appeals also upheld the death sentence, and on March 12, 2014, dismissed Kijima's appeal. On that same day, she decided to appeal to the Supreme Court. Supreme Court appeal. Kijima married in prison after the appellate court's decision, and had her last name changed in 2016. The Supreme Court, headed by judge Yoshinobu Onuki, decided to have the first opening session on February 10, 2017. On said date, the defense court argued that "the men may have committed suicide" at an oral hearing. This was not supported by any facts, and the prosecutor dismantled , contributing to the dismissal of the appeal. On February 22nd, the judgment date was set for April 14th. On April 14, 2017, the Supreme Court Judge Yoshinobu Onuki said, "The killings are intentional and extremely malicious. The defendant has irrational excuses and shows no remorse. Thus, the death penalty is unavoidable." With this, her death sentence was officially confirmed. On May 9th, the Supreme Court dismissed allegations of prejudice against Kijima. She is the 15th woman to be condemned to death in the post-war period, and the first to be convicted by a lay judge. Since 2019, Kanae Kijima  is incarcerated on the Tokyo Detention House's death row.
