What are the unsolved cases in the world?

At the end of 2000, the Miyazawa family in Tokyo, Japan was killed. It was that Japan offered a reward of 20 million yuan to solve this case, which was also the highest reward case in that year, but it has not been solved so far.

On June 30, 2000, 65438+February 30, the family went to the supermarket to buy the new year's goods needed for the New Year. This is the last time people see their families. They have never been out since they got home. Grandma who lives next door doesn't answer the phone and knocks on the door. She felt something was wrong and found a spare key to open the door. As a result, she was stunned by everything in front of her, which made her more miserable. She saw her son-in-law, Gong Ze, lying on the stairs leading to the second floor, without breathing, with many knife wounds. She hurried to the second floor to see her daughter and children. When she went to her grandson's room, she saw the obvious ligature marks on his neck. His grandson was strangled alive, and then she saw her daughter and granddaughter die on the steps leading to the attic, with multiple stab wounds behind them. She immediately called the police. After investigation by the police, she found footprints and broken branches of nearby trees on the guardrail outside the toilet window on the second floor. It is speculated that the murderer should have turned into Miyazawa's house at about 12 on the afternoon of February 30, 170- 180, and initially identified a male with a height of about 170. He went to bed that night and went through the second floor. I advanced into my brother's room, strangled my sleeping brother with my bare hands, and left footprints by the bed. Father heard the noise downstairs and went to the attic to check. I happened to meet the murderer, who took it out and cut it in Gong Ze. Gong Ze kept resisting, and finally he was stabbed to death. According to the police analysis, the murderer made up several more knives after Gong Ze's death.

The murderer went to the third floor again, saw the sleeping mother and daughter, and cut them off with a knife. When the murderer got it, he found himself injured, so he went to the kitchen on the first floor to get it, and then went back to the third floor to hack the mother and daughter to death. The forensic report shows that the number of knife wounds on the mother and daughter is far more than the number of deaths, which means that the murderer cut several knives on the mother and daughter after confirming the death of the mother and daughter, which shows the cruelty of the murderer. At first, the police thought it was a burglary, but later, after leaving clues at the scene, they did find many strange doubts.

After killing the Miyazawa family of four, the murderer did not leave directly, but stayed here for more than 10 hours. First of all, he calmly found a medicine box to bandage the wound caused by the struggle of the host, left fingerprints on the band-aid and a bloody towel. During this period, he tried to stop bleeding with female sanitary napkins. According to the police analysis, the way of dressing is like a common method used by soldiers, and we have to suspect that this person has been a soldier. Moreover, he opened the refrigerator, drank wheat tea, ate two ice creams and a cantaloupe, and put them in the living room and bedroom respectively. During this period, he also turned on the computer twice, both of which took less than 5 minutes to turn on, and the second time was around 10 in the morning. Browsing records are the company where the deceased is located, as well as professional websites such as university research rooms and science and technology. He also tried to book tickets for the drama troupe, but without success. After satiated with food and drink, he ransacked all the money at home, but only took Gong Ze's wife's 1.5 million yen, but did not take away the obvious 60,000 yen in the study. What is even more incomprehensible is that he also took the New Year card prepared by the Miyazawa family. Generally speaking, the murderer will flee the scene quickly after killing, and this murderer can stay with four bodies 10 hours, eating and drinking online, which shows the psychopathic index and cruelty of the murderer. The murderer in this case left a lot of evidence and clues, including T-shirts, knives, fingerprints, blood and footprints. He didn't deliberately clean up the scene, stayed leisurely until dawn, and didn't thoroughly search the property.

Through analysis, the police believe that the murderer is a symbolic search for property, which often makes people think it is burglary. Although there are many leftovers, most of them are daily necessities, so it is difficult to check and find key evidence. According to the DNA identification of blood, it is analyzed that the father of the murderer is Asian and the mother is European. Judging from the footprints, the killer's shoes are 28 cm, while the same shoes in Japan are only 27.5 cm. The 28 cm shoes are only sold in South Korea and Britain, so the killer may be Korean, but the 28 cm shoes are 46 yards, which may be European. There is so much evidence that the case has not been solved, which means that this person has no ID card in Japan. Japan has produced many language profiles and posters about this case, hoping to solve the case, and even offered a reward as high as 20 million yen, but it has not been broken so far.

At 3pm on September 6th, 2000/kloc-0, Su Quanxi, general manager of Zhongyuan Enterprise Company in Zhang Bin Industrial Zone, came to the home of Hong Ruotan, the person in charge of the company. This is a big building, which is located in Erlin Town, Li Lu. Su Quanxi came here because the company check was due and needed Hong Ruotan's seal.

After Su Quanxi came here, he rang the doorbell and didn't respond. He felt a little incredible, so he climbed over the wall and went into this mansion to find it.

There is no one in the building. Su Quanxi found three suicide notes on the table and other places, all of which were left to Hong Ruotan's sister Hong Yuyan.

Feeling a big problem, Su Quanxi quickly called the police. After the police arrived, they made a detailed search. As a result, a brand-new incinerator that can accommodate four people was found in the small garden behind the house. There are two pairs of slippers under the incinerator and a shredder next to it.

The police tried to open the incinerator and found that the door of the incinerator was actually tied with inner wire. When the police opened the incinerator, they found two charred bodies. In addition, in the grinder, the police also found a human bone one centimeter in size.

The police also found a suicide note at the scene, which said that all three children in the family had been burned to death and all the ashes were scattered into the sea.

Mr. and Mrs. Hong Ruotan have three children, all of whom are adults. Hong Chongfu, the eldest son, is 24 years old and studied at the Institute of Physics of Chung Yuan Christian University. The second son, Hong Chongzuo, is 23 years old and works in his own company. The youngest daughter Hong, 19 years old, is still studying.

Mr. and Mrs. Hong Ruotan were in the incinerator, but did they really burn all three children to death? The police searched the big yard carefully and found no trace of the child being killed. Before committing suicide, Hong Ruotan burned almost all family information and photos.

According to the survey, Hong Ruotan's career before his death was not bad. The Zhongyuan company he founded specializes in making adhesive tapes and stickers. His big house is 3000 square meters, just like a small castle.

But this land was left by his father to his brothers because Hong Ruotan's brother had a loan relationship with him. So Hong Ruotan took the land for himself and built this mansion and high-walled compound for his family to live in.

Hong Ruotan's personality is a bit eccentric and difficult to get along with, so even his mother thinks that Hong Ruotan is a bit harsh on his brothers and doesn't want to live with him. And Hong Ruotan is meticulous and rigorous.

Hong Ruotan's first wife had already died in a car accident, and his current wife Yao listened to Hong Ruotan very much. Hong Ruotan asked Yao not to have another child after marriage, but to fully support the three children of his first wife. Yao agreed and had an operation to terminate the birth.

A few months before the bloody case, there was a big-character poster in Erlin vegetable market, pointing to Hong Ruotan robbing his brother's property. Neighbors talked about it, and Hong Ruotan's mother also told her neighbors that Hong Ruotan was not good, and her neighbors wrote to vent their anger.

But for Hong Ruotan, he is really a little wronged. His father once borrowed 3 million yuan, which was returned by Hong Ruotan. He felt that he should own the land at such a high price.

In short, the neighbors and friends outside have been gossiping, and it is widely rumored that Hong Ruotan is unfilial.

Is it because of the scandal that Hong Ruotan committed suicide with his family? Obviously not. The investigation found that Hong Ruotan was in financial difficulties.

Because of the economic depression, Hong Ruotan's company has encountered difficulties. He mortgaged the factory equipment and residential land to the bank, borrowed 260 million from the bank, 76 million from private banks, and also borrowed money from some underground banks. ...

In this way, Hong Ruotan is indeed heavily in debt.

In short, Hong Ruotan made a detailed suicide plan. He bought an incinerator and a shredder and burned all his information, hoping to leave nothing behind.

According to the investigation, after injecting anesthetic into the bedroom, Mr. and Mrs. Hong Ruotan went to the incinerator in the backyard to set up their shoes. The incinerator is automatic. After Hong Ruotan set the temperature and time, they went into the incinerator.

Then, Hong Ruotan tied the door with wire inside. At that time, the incinerator was already running and the temperature was extremely high. After a reflective struggle, Hong Ruotan, who was not in a coma, suddenly knocked down the door of the incinerator, resulting in insufficient temperature in the furnace, so that the bones of the two men were not completely burned to ashes.

Although Hong Ruotan said in his suicide note that all the children were dead, the ashes were scattered into the sea. However, the police did not find any relevant traces. The blood of three children was found in the bedroom, which was suspected to be caused by injection needles.

Could it be that Hong Ruotan controlled the child with drugs while he was sleeping, and then killed and burned him? According to analysis and reasoning, this is very possible. It's just that the only nail-sized bone found is too carbonized to detect DNA.

No one knows whether these three children are dead or not. Eight years later, the court decided to confirm the death.

Hong Ruotan's home has become a "haunted house", and various horror stories have also spread. In 2006, Hongjia Haozhai was sold and turned into a leisure farm.

I think the Nanda dismembered body case must be a famous mystery on the list!

Brief introduction of the case:

1996 65438+1October 10, a girl in a dormitory in Gulou campus of Nanjing University violated the school's regulations on the use of electrical appliances, which led to the punishment of Diao Aiqing, the person in charge of the dormitory. Diao went out to have fun in a bad mood and never returned to the dormitory. A few days later, the girls in the same dormitory saw an advertisement for recognizing the body from Nanjing Daily. The clothes described in the advertisement were very similar to those of Xi Ai Qing. Several students went to the appraisal site with the school. The deceased was identified as Xi Ai Qing, and his head was boiled red and cut neatly.

The time when the deceased was found was 1996 65438+ 10/9. A snow sweeper found a bag full of sliced meat on Huaqiao Road near nanjing xinjiekou, and found three fingers when cleaning at home, so he called the police. Later, other parts of the body were found in Shuizuogang Road and Longwangshan, all wrapped in bags and a sheet. After the body was cooked, * * * was cut into more than 2,000 pieces. The knife work was very fine, and the clothes and intestines of the deceased were neatly packed, showing the cruelty and strong psychological quality of the murderer.

Victim's situation:

Diao, female, was born in March 1976. She is a first-year student in the full-time adult education class of the Information Management Department of Nanjing University Gulou Campus, where she studies and lives. She was less than 20 when she was killed. She lived in four dormitories in the south campus of Gulou campus, which was complicated and mobile at that time. According to the memory of Diao's friends before his death, Diao is about 1.65 meters tall, with a moderate figure and average appearance. Short hair, single eyelid, slightly nearsighted eyes, reading and writing will wear glasses. There is a mole in the upper right corner of the mouth, the size of rapeseed. When you speak, your voice is a little hoarse and your speech speed is very fast. One detail is that the girl who writes this word beautifully sometimes deliberately complicates her name and calls it "Diao Aiqing".

Post-crime investigation

After the incident, the Nanjing police attached great importance to it and set up a task force to station in Nanjing University. At that time, almost all the residents nearby were investigated. The police officer involved in the investigation said: The murderer is very cruel. We found more than 2000 bodies, each of which was cut very neatly. Judging from the way the murderer dismembered the body, he should be more professional and have a certain degree of understanding of anatomical knowledge. I saw the hands and feet of the deceased with my own eyes and dismembered them neatly. The victim's head and internal organs were cooked. Because there was no DNA technology at that time, the forensic doctor could only confirm that the deceased was a woman by the characteristics of body hair and muscle fibers on the corpse.

After the case was detected, the task force launched a sea of people tactics and conducted extensive and detailed investigations. At that time, almost all police officers in Nanjing participated in the case to varying degrees. Some were transferred to the task force to participate directly, and more were investigated in their own jurisdiction. At that time, most of the places where the killers dumped their bodies were concentrated in downtown areas, as many as five or six. Anything that appears at the scene of the body dump, such as a garbage can, will be checked one by one as long as it has been emptied. According to the location where the murderer dumped the body and related investigations, it is speculated that the murderer should live near the university campus, and it is likely that he dumped the body by bicycle.

According to the murderer's dismemberment technique, Nanjing police once determined that the murderer was a doctor or a butcher, and conducted extensive investigations on those who met the conditions for committing crimes. Because the victim is a freshman, her contacts are not extensive, and the girl is introverted and simple, which brings certain difficulties to the police investigation.

The photo of the murdered girl was officially posted on NTU campus. All the students were investigated to provide witnesses who were not on the scene on the night of the incident. At that time, the media reported relevant news and explanations, the police announced a reward notice, and announced several bags and a printed sheet involved, hoping that the public would provide clues. However, the time limit for solving the case has passed and the case has not progressed.

After many years, I hope to solve the case as soon as possible.

Although it is difficult to solve the case, the police are still pursuing it. At least every time a new technology appears, the original physical evidence will be re-identified.

Although this case has been difficult to solve, according to the laws of China, it will not expire. There is only one possibility that the prosecution will fail, that is, the murderer died of other reasons. Even so, I have seen the death of the suspect, and the police opened the coffin for autopsy to confirm or deny this person.

Therefore, the future of the Nanda dismembered body case is not without a turning point. I just hope Diao Aiqing can rest in peace. Leave the rest to the police who are constantly looking for the truth in order to safeguard justice!

Tell me about one of the most mysterious disappearances in the world, the disappearance of Madeleine McCann. The disappearance caused a sensation around the world, and the investigation process was bizarre and tortuous. The little girl disappeared 12 years and was "witnessed" more than 8000 times. ...

Madeleine McCann was born in a middle-class family in Britain in 2003. On May 3rd, 2007, she spent a holiday with her parents and a family of four at Luce Beach in Algavi, a Portuguese tourist resort.

At 8 o'clock that evening, Mr. and Mrs. McCann settled their three children in the apartment of the resort, and then went to the bar Ocean Club 50 meters away to have dinner with friends. The couple take turns to go back to see the children every half hour.

At night 10 When it was Kate's turn to go back, she found the light on in the room, the door was half open, the window was open, and a twin baby was lying on the bed, but Madeleine was gone.

The McCann couple immediately reported the case. However, the Portuguese police did not immediately classify this short-lived disappearance as a formal case, and did not even block the first scene. They are still in no hurry to investigate, and the resort is not covered with cameras, so the investigation has not progressed.

A friend of Maccann's saw a man leaving with a child in pajamas on his way back to see the child around 9: 0015 that night, and then he got the magical portrait of the suspect.

Because some friends of the McCann couple are familiar with the media, they told the British media about it, hoping that many hands make light work and we can help find the children together. It is precisely because of the exaggeration of the media and the unfavorable handling of the Portuguese police that this disappearance case quickly fermented, from finding children to the contradiction between Britain and Portugal, and then became global news.

Portuguese soccer stars Cristiano Ronaldo and Paulo Ferreira, as well as British soccer star David Beckham, all appealed to the media to help find the children.

Murat lives in a villa less than 150 meters away from the crime scene. More dramatically, he has a 3-year-old daughter who looks almost like Madeleine.

His home was searched closely, and he was tried, but it was rejected for lack of evidence. Murat subsequently sued 1 1 British media for libel, and finally won the case and received 600,000 pounds in compensation.

Subsequently, McCann and his wife, both doctors, were listed as major suspects by the police. The police suspected that his wife Kate had given the child too much sedative, which led to the accidental death of the child, and then the husband disposed of and destroyed the body with a car.

Police dogs found bodies and blood smell in apartments and rented cars. Portuguese police said there were suspicious blood and Madeleine's hair in the car, and sleeping pills were detected in the hair.

But in the end, McConn and his wife were rejected because the samples were seriously polluted and no valid conclusions could be drawn. The fact is that Portuguese police tried to induce Maccann and his wife to confess with false DNA evidence. Because the Portuguese inspector in charge of this case has a black history of extorting confessions by torture and forging evidence, he also resigned after this incident.

The Portuguese police announced the end of the investigation in 2008, but McCann and his wife found new clues through detectives. Scotland Yard restarted the independent investigation on 20 1 1. At present, it has spent nearly 1 100 million yuan, read more than 40,000 documents and surveyed more than 600 people.

The police expanded the scope of investigation and found that one or more suspected pedophiles were active nearby on the day of the crime, because the police received 12 cases of suspected sexual assault and harassment of children. In addition, a group of strange men snooped around to raise money for the non-existent orphanage, which is also very suspicious ... The increase in clues brought hope for solving the case, and the police are still investigating.

Almost every year, the police synthesize Madeleine's photos to simulate what she might look like now, hoping that someone can find her. In recent years, the police * * * received more than 8,600 witness statements from 10 1 countries, thinking that they had seen "Madeleine", but it was either not true or it was too difficult to trace it across borders.

I hope Madeleine is still alive, I hope to find her as soon as possible, and I hope all the missing children can go home.

This unsolved case has a bad social impact because the deceased was not only a lovely child star, but also her parents and brother were involved in the terrible suspicion of murdering her after her death. This has brought multiple social injuries to the Ramsey couple who lost their beloved daughter, adding salt to their already painful wounds.
