An unsolved murder case in Dengzhou, Shandong Province in the Northern Song Dynasty. There is a family named Liu in Dengzhou, Shandong Province. There is a daughter named Liu. She is 28 years old and looks very beautiful. This spring, Liu's mother was seriously ill, because her family was poor and she had no money to treat her. There is a Wang Xingren in Wangjiawan, a neighboring village. His son is Wang Xiaoliu, who is nearly 30 years old and unmarried. The reason is too ugly. Grandpa Wang heard about the Liu family and rushed to the Liu family, expressing his willingness to pay for Mrs. Liu's treatment, but on the condition that Liu would marry her son. Liu didn't want to hear the name for a long time, but if she didn't treat her illness, her mother would die. After careful consideration, Liu gritted his teeth and agreed to this marriage. After the marriage of Liu Wang and his wife, although the young couple's life is not harmonious, they have been living in peace. It's autumn harvest season in a blink of an eye. One day, it was so hot that the Wangs rested at home during the day. In the evening, Grandpa Wang arranged for his son and daughter-in-law to harvest rice in the field while the night was cool. At about midnight, Liu suddenly ran home crying. Her face was frightened. She shouted murder, murder. It turned out that Wang Xiaoliu was killed on the battlefield, with a dozen knives in his body, and his death was very tragic. Accompanied by villagers, Mr. Wang reported the case to the government office, and the government office immediately sent a section chief to investigate the case. There has been no murder in Wangjiawan for nearly 40 years, and the Wangs have no rancour in the past. Wang Xiaoliu is even more honest. No useful clues were found at the scene, and officials found nothing. Just when the case reached a deadlock, news came from the village that Liu was too ugly, and then someone was outside, and then a joint lover murdered her husband. Beautiful and ugly. It's original. After the murder, the rumor of "murdering my husband" appeared at this time, which was just in line with the public psychology. So three plus salt and five plus vinegar became peach news, which quickly sensationalized the whole Dengzhou. It wasn't a big case, but now public opinion is rampant, and if we don't solve the case, the magistrate in Dengzhou is worried that he will lose his job. So, in line with public opinion, Liu beat him to confession and sentenced him to death, which was reported to Dali Temple and forwarded to the ruling. When Dali Temple reexamined the case, it found that the evidence was insufficient, so it hit Song Shenzong. Song Shenzong thought the case was very interesting, so he called all the ministers to discuss it. When everyone was discussing, Prime Minister Wang Anshi said nothing. Song Shenzong then asked, "Mr. Fu Jie, what do you think?" ? Wang Anshi replied that it is unfair to be extremely beautiful and ugly, so the origin of the case is caused by the mismatch of marriage, so it is reasonable to reduce the sentence and spare the woman's life. Song Shenzong said with a smile, this speech is unconventional and bold. Isn't Mr. Wang's eclectic style necessary? In a word, in a word, it suits me very well. The ministers were dumbfounded, and a murder case was decided between the monarch and the minister. Whether Liu is guilty or not, whether he died unjustly, all this has become an unsolved mystery. There is also a famous unsolved serial murder case in modern history, Jack the Ripper, who killed five people in a row and wrote letters to provoke the police many times. He became famous in the media at that time, causing great panic, so that he is still one of the most famous killers in Europe and America, and his related works continue. The first murder in Jack the Ripper took place on August 7th. 1888. The deceased was a middle-aged prostitute who died miserably. She was stabbed 39 times, including 9 times in the throat. ? The second victim appeared on August 3rd1day, and the third victim was found on September 8th, all middle-aged. On September 9th, the Central News Agency received a postcard signed by Jack the Ripper, indicating that it had planned to cut off the victim's ear and give it to the police. On September 25th, the Central News Agency received another postcard from Jack the Ripper, saying that it was the murderer and would continue to kill people. On September 30th 1888, a fourth victim appeared, but due to different techniques, it is generally considered as a poor imitator. However, when the police arrived at the scene, another body appeared in Bishop's Square. The deceased was 46-year-old * * *, and the modus operandi was the same as the previous ones. The police and the media received a large number of letters claiming to be murderers, so many that it was inconclusive which ones were really written by murderers. However, with so many murders in a short time and the follow-up of the media, this case has aroused great concern, and Jack the Ripper has thus become a world-class murderer. The police speculate that there are as many as 200 suspects, and even some celebrities are involved. Of course, it was not confirmed in the end. Jack the Ripper also appeared repeatedly in western popular culture. In 20 14, a British forensic expert claimed that the real murderer was identified by identification, but it was soon questioned because his characteristic fragments as evidence were common in eastern Europeans. Although this matter is still controversial, it shows how great this case was more than 100 years ago.
