Can a policeman find out other people's crimes?

Jack The Ripper is the nickname of the murderer who killed at least five prostitutes in Whitechapel, East London, from1August 7, 888 to 1654381October 9. During the crime, the murderer repeatedly wrote to the relevant units to provoke, but never fell into the French Open. Its bold criminal methods were repeatedly exaggerated by the media, which caused panic in British society at that time. He is still one of the most notorious killers in European and American cultures.

Although it has been a hundred years since the crime, there are more and more books and related research on the case. However, due to the lack of evidence, there are different opinions about who is the murderer, and there is no intersection, which makes the case more confusing. However, Jack the Ripper's figure is constantly appearing in today's popular culture through media, rock music, toys and other items.

The location of the crime The ripper's crime was concentrated near Whitechapel in East London. It was a famous immigrant distribution center at that time, and tens of thousands of immigrants from Russia and Eastern Europe settled here. Because of the meager income, it has long been a hotbed of poverty and crime, and homeless hooligans and prostitutes live on the streets. Although Scotland Yard has established a city-wide patrol network in 1829, the weak police force is still unable to bear the security of the East District where tens of thousands of prostitutes haunt every night.

[Edit this paragraph] It was not until the 1990s, that is, 100 after the Whitechapel serial murder, that people had a more comprehensive understanding of Jack's modus operandi. So we can infer many characteristics of Jack:

First of all, he must have a considerable knowledge of anatomy.

B, considering the environment at that time (outdoor, basically no lighting, I have to be alert to the surrounding situation at any time, extremely tense time), Jack must be a skilled knife user.

C, all the victims were stabbed from right to left by a knife, which means that Jack is probably left-handed or skilled in using knives with both hands. This speculation indirectly indicates that Jack is probably an experienced doctor or anatomist.

D, it's possible that Jack didn't do it alone. This inference is widely accepted by "royal conspiracy theorists", but there is no evidence that Jack has an accomplice.

E, Jack must be a man with some physical strength.

The last one became the main flaw of the "Royal Conspiracy Theory". William Gul, a suspect in the royal conspiracy theory, is thought to have been over 70 years old when he committed the crime. Such an old man, no matter how good his anatomical skills are, his physical strength does not allow him to carry out such a laborious murder.

[Edit this paragraph] After the murder, the first message sent by the suspect was "Dear Boss" 1888. On August 7, a female corpse was found dead in Whitechapel, Eastern District. The deceased was a middle-aged prostitute, Martha Tabram. She was shot 39 times, nine of which cut her throat. At 3: 45 am on August 3 1 of the same year, another prostitute, Mary Ann Nichols, was found dead in Bucks Row near Whitechapel at the age of 43. Not only was her face bruised, some front teeth fell off and her neck was cut twice. But the most cruel thing is that the abdomen was cut open, the intestines were dragged out, and the vulva was seriously stabbed by a sharp knife.

Because there are few murders near the church, these two cases and several previous murders have attracted public attention, and some media even called them "Whitechapel murders" and thought that the same murderer had done them. This vivid description caused panic among local residents, so the police sent more plainclothes detectives to patrol here, and local residents also organized patrols to maintain law and order. This makes people believe that such cases will not be repeated.

Unexpectedly, eight days later, at 5: 45 a.m. on September 8, an old driver living at No.29 Hanbury Street took advantage of this opportunity.

A female body was found in the fence behind the rented apartment. The deceased was 47-year-old prostitute Anne Chapman. Like the previous victims, her throat was cut, her abdomen was cut, her intestines were left on her right shoulder, and part of her uterus and abdomen were cut off by the murderer. He had obvious ligature marks on his neck. It is said that he called for help before he died, but he ignored it. Because it was the first time that the murderer committed a crime near the house, it was still close to 5 am, but there was no obvious noise. This case became the most famous case committed by the murderer who will be called the Ripper in the future.

On September 27th, the Central News Agency received a letter written in red ink, covered with handprints and signed "Jack the Ripper". In the letter, he joked that he was the murderer of prostitutes and claimed that he would continue to kill more prostitutes before he was arrested. Since this letter begins with "Dear Boss", it will be called the first letter sent by the murderer in the future.

At one o'clock in the morning on September 30th, a coachman found the body of Elizabeth Strede near her home. Unlike the first two victims, the 44-year-old Swedish prostitute died of excessive blood loss from the left carotid artery. Although her throat was cut, she did not have a laparotomy. Because of the different modus operandi, some people suspect that the murderer in this case is not directly related to the first two murders by caesarean section.

When a large number of police arrived at Elizabeth Staade's morgue, Catherine Eddowes, a 46-year-old prostitute, was found dead in Mitte Square at around 1 45 am. In addition to being cut throat and laparotomy, the intestines were thrown to the right chest, and some uterus and kidneys were deprived. Since the patrol police claimed that there was nothing unusual here at 1 30, it was inferred that the deceased was killed between 1 30 and 1 45, and his abdomen was cut open. The killer's neat modus operandi made most people think that he might be a professional surgeon.

At three o'clock in the morning, a policeman searching for a suspect found a bloodstained dress near Gaszton Street, which was identified as part of the apron worn by Kathleen Erdos. On the high wall near where the clothes fell, a line written in chalk by the suspected murderer was found: "Jews are not a nation willing to be resented!" " ("Zhu Wei people will not be hacked for no reason") But another policeman remembers that "Zhu Wei people will not be hacked for no reason". Later, police chief Thomas Arnold visited the scene and read the news. He was afraid that the graffiti on the wall would be seen by passers-by after dawn, but it aroused anti-Semitic feelings and ordered it to be erased on the spot.

The day after the last victim, that is, 65438+1 October1,the Central News Agency received another postcard with the words written in red ink. In the letter, the writer called himself "saucy Jacky" and mentioned that he planned to "do two more things the next day"-generally believed to be two murders of Elizabeth Stade and Kathleen Erdos in the early morning of September 30th. In addition, the author mentioned that he planned to cut off the dead man's ear and give it to the police, which was similar to the case that Catherine Erdos' external ear was damaged. Finally, the writer left the generic name of "Jack the Ripper". In the future, this letter will be called "Saucy Jacky" by the author.

10 On June 5438+05, a letter sent to the Whitechapel Alert Committee spontaneously formed by residents around Whitechapel once again attracted everyone's attention. There is half a kidney in this letter, which is written in black ink. The screenwriter claimed to be "from hell" and said that this kidney was taken from "a certain woman" (generally thought to be Catherine Erdos), and half of it was fried and eaten by him. Different from the first two letters, this letter has no signature, and people will name it with "from hell". Compared with the first two letters, it is generally believed that this letter is most likely written by the murderer himself.

165438+1October 9, a landlord in Dorset Street sent an assistant to Mary Jane Kelly's room to collect six weeks' unpaid rent, but found the 25-year-old young prostitute dead in bed from the window: she was naked, with ligature marks on her neck, her chest and abdomen cut off, and her face, ears, nose and breasts were also cut off. It is said that she was cut off. One neighbor claimed that Kelly was alive at 8: 30 last night, that is,165438+1October 8 (although her description of Kelly's appearance was not completely correct), and another neighbor claimed that she heard a miserable female scream around 4 am that day. But what is certain is that Kelly appeared in the bar at 10 the night before the body was found.

After the murder of Mary Jane Kelly, Jack the Ripper seems to have disappeared: there is no similar murder method in London, and the media's interest in this murder has gradually faded. However, the police mobilized a lot of manpower, but failed to solve the case, which was criticized by people from all walks of life in Britain, including Queen Victoria, and led to changes in the top management of the police. 1892, the police announced that they would stop investigating the serial murders in Whitechapel.

[Edit this paragraph] Overview of the Ripper's Letters During the whole process of the Ripper's crime, the police and the newspaper industry received hundreds of letters about the case. Some letters come from people who wholeheartedly provide information to help catch the murderer, but most letters are ignored because they are considered not helpful to the case.

Perhaps among the hundreds of letters, the most attractive ones are those claiming that the murderer wrote them himself. Most of these letters are considered as scams. Many experts pointed out that "none of these letters are true", but they probably contain the real murderer. Verified by modern and present authorities, three letters are the most striking:

Letter from "Dear Boss": dated September 25th, postmarked September 27th, sent to Central News Agency, and sent to Scotland Yard on September 29th. At first, this letter was considered as a scam, but when aldous's body was found to have one ear partially cut off, this letter proved to be "cutting off the ladies' ears", which attracted people's attention. The police released this letter on June 10, hoping that someone could recognize the handwriting in the letter, but in vain. The name "Jack the Ripper" first appeared in this letter, and gained world-class notoriety after it was published. Most meaningless letters imitate the style of this letter. After the serial murder, the police announced that the letter was a scam by local journalists.

Naughty Jack postcard: postmarked 1888 10 10/0/0/0/,addressed to the Central News Agency. The handwriting inside is similar to "Dear Boss Letter". The letter mentioned that two victims (Stade and Aldous) would die near each other: "This is a double incident." . Controversially, the letter was sent before the murder was announced, and it doesn't look like it was written by a weirdo with such criminal knowledge, although the postmark was sent 24 hours before the murder, and the details behind it were also known to local residents and journalists. Later, the police station announced that it had confirmed that the letter was written by a specific reporter, who was also the author of Dear Boss's Letter.

Letter from Hell: also known as Lusk letter, postmarked 10/0/0/5, received by George Lusk of the White Church Alert Committee on 1888 10/6. When Lusko opened the small box attached to the letter, he found half a kidney in it. The doctor who kept it in the spirit of wine (ethanol) said that this is a human kidney. One of aldous's kidneys was taken away by the murderer, and the doctor thought that the kidney sent to Lusco was "like that taken by Catherine aldous", although his findings were very unreliable [1]. The author of this letter claimed that the other half of the kidney had been "fried and eaten". The story about this kidney is inconsistent: some people insist that it belongs to aldous, but others think it is just a "horrible prank, that's all."

In some places, another letter will be listed, that is, the date is 1888 September 17, which is considered as the first message using the name Jack the Ripper. Experts believe that this is a modern fake that was only put into police files in the 20th century, and it has been a long time since the ripper committed the crime. They realized that the letter had no police seal to check the date of receipt, and no early investigator had checked whether it was potential evidence. In addition, there was no mention of this letter in any police file at that time. Some people who read the letter claimed that it was written with a ballpoint pen, which was invented more than 50 years after committing crimes in Jack the Ripper.
