Korean man in his 20s charged with murder after killing Japanese couple for 2.5 million yen - Korean reports

In connection with the case in which the body of a couple in their 50s was discovered in Nasu Town, Tochigi Prefecture, a Korean man in his 20s who is believed to be the perpetrator has been charged with murder.
According to Japanese media, including the Yomiuri Shimbun dated the 21st, the Metropolitan Police Department issued a statement on the same day requesting that a Korean man, Mr. A (20), and a Japanese man, Mr. B (20), both have existing assets.
The police plan to add a murder charge to the charge of mutilation. A high-pressure washer was found in the garage at the scene of the murder of the Japanese couple, and the police believe that it was used to wipe away bloodstains.
They are suspected of murdering a Japanese couple who run a restaurant in the garage of a vacant house in Tokyo on the 15th and 16th of last month.
An electrical cord and a hammer with bloodstains from the victim were found. Japanese police say they killed the Japanese couple by strangling them with an electrical cord and hitting them with a hammer, then used a high-pressure cleaner and other tools to kill them.
It is believed that they were trying to cover up the scene of the murder. It is believed that this case was a "multi-stage" murder contract. Of the four arrested suspects, Mr. C (28) was paid 15 million yen to commit the murder.
After receiving 1 million yen, Mr. C, who was asked by a client to carry out the case, re-assigned Mr. D (25). Mr. D received 9 million yen and paid 2.5 million yen each to Mr. A and Mr. B as compensation.
The Metropolitan Police Department suspects that Mr. E (32), a company executive who is in a common-law marriage with the victims' eldest daughter, ordered the murders. None of the four suspects knew the victims or their parents, and they are the "executors."
The two men, A and B, did not even know each other's real names. In Japan, the problem of "illegal part-time jobs" where people commit crimes on behalf of others in exchange for high rewards has recently emerged as a social issue.
The crime occurred through an illegal part-time job system in which the crime was divided among a perpetrator, an intermediary and an executor.
