Analysis of the kidnapping case in Osaka basement;

At the first time when the police found that the soles of Tianmou Meibo shoes were stained with glass residue, they tested the materials with the broken glass at the crime scene and found that they all belonged to the same material, and the luminol reaction was detected on them. In the face of conclusive evidence, Tian had to admit that he had indeed been to the crime scene, and had long found that vilen in the Orange River was killed, but the murderer was not himself.

The police think that the murderer must be wearing vilen's coat, otherwise there is no way to explain why there is blood spattered on the coat and shirt of the deceased. At the same time, the murderer probably didn't commit the crime with gloves, because there were no fingerprints on the baseball bat as the murder weapon, which means that the murderer wiped it, and in the process of wiping, the fingerprints of vilen, the owner of the baseball bat, were also wiped off. As a result, the police set their sights on Tian Zhongmeibo and Matsumoto Mountain with fingerprints on their coats. Among them, Tian Zhongmeibo had sufficient alibi during the death of the deceased, so Matsumoto Mountain naturally became the first suspect. After repeated inspections and tests by the police, ferroferric oxide and chloroform were finally detected on the sleeves and hands of Matsumoto Mountain. In the face of a lot of evidence, Matsumoto confessed to his murder. The police also figured out Matsumoto's double-room killing scheme in his statement.

Three years ago, Mibo Tanaka and vilen had an operation in the Orange River. The object of the operation was Miyamoto's father, but during the operation, Miyamoto's father was infected by the operation because of his negligence and finally died on the operating table. For the sake of the hospital's reputation, the dean chose to hide the truth about vilen, and vilen threatened to be his lover, which also explains why there are so many articles about women in vilen's family. Tian Zhongmeibo went to vilen's home in Tang Chuan at 16:00 as usual, but he was surprised to learn that vilen of Tang Chuan invited her husband Matsumoto, so he left in a hurry. In desperation, Tanaka's Shoubainian brand cigarette was left on the table of Yuanye's home in Orange River, and was seen by familiar friends when he left. Matsumoto Mountain arrives at Orange Yuan Ye's home at 18: 30. When the two discussed how to make up the advance payment that had not yet passed the hospital account, Miyamoto Yoshinori arrived at Kurokawa Yuanye's home at 20:00 with ten million yen as promised. In order to prevent things from being exposed, Matsumoto hid in the bedroom, but in the bedroom he saw the women's clothes in the closet, which he had seen his wife wear. At this time, he remembered the Shoucentennial cigarette that had just been served on the table, because Shoucentennial cigarette is a female indigenous cigarette, and it is only produced in Britain, and vilen has never been to Britain. Matsumoto seemed to understand something at this time, so after Miyamoto left, he came out of the bedroom and asked Yuanye and his wife if they had any questions. Proper relationship, but Yuan Ye of Orange River generously admitted his lover relationship with China and the United States, which made Matsumoto feel very angry and punched Yuan Ye in the face. Orange Sichuan yuan also fought back, but I didn't expect Matsumoto Mountain to faint with one punch. Seeing Matsumoto Mountain faint, Orange Chuanyuan was also a little panicked. He waited for a while, but when Matsumoto Mountain didn't wake up, he went to the kitchen to contact the water to wake him up.

When the orange river meets the water in Yuanye, Matsumoto Mountain wakes up and hears the sound of running water in the kitchen. He put on vilen's coat, picked up a baseball bat and walked to the kitchen. Seeing Yuan Ye's back to himself, Matsumoto hit him on the back of the head with his greatest strength. He leng leng, until return to absolute being, only to find that vilen has been killed by him. But Matsumoto was not in a hurry to escape. He thought of Shigeru Miyamoto, who had just come, and Tomoto Ichiro, who was locked in the basement. He came up with an idea. He first took off his coat and put it aside, then cleaned the shoes and baseball bat stained with blood, wiped off the fingerprints on the baseball bat and put it on the porch. He remembered what Oragawa told him about Toyoda Shoichiro, so he went to his bedroom and found a bottle containing chloroform. In order to prevent fingerprints, Matsumoto chose to dip a small amount of chloroform in his sleeve, then took some magnets on the table, opened the lock in the basement, climbed down, and locked the old-fashioned iron gate outside with magnets from the basement. Later, Matsumoto went to his unconscious friend Ichiro, set his watch back 1 hour, and woke him up to think it was 20:40, so that he could serve as his alibi. Later, Matsumoto Mountain asked Zhiduolang to lock the basement with a belt on the grounds of preventing Yuanye from coming in and killing them, and forged it into a double two-way secret room. After confirming that Tomoto Ichiro tied the bolt, Matsumoto pretended to be asleep. After Tomoto Ichiro fell asleep, he adjusted the time of his watch, then inhaled chloroform that had already been prepared, pretending that he was kidnapped by Yuanye in the Orange River.

At zero o'clock in the field, Meibo came home from work and found that Matsumoto Mountain was not there and could not be contacted. Anxious, he still couldn't help looking at vilen's house, but found vilen's body in the kitchen. Panicked, Tanaka realized that her husband might have killed her, so he dragged the body to the bedroom cupboard, washed the blood and put on new clothes, and took out the clothes stained with blood and threw them away. Tian Zhongmei, who has not recovered from the panic, returned to the hospital and sat in the lobby on the first floor thinking. She is afraid that her husband will kill and abscond, that her identity as a lover of Orange River and vilen will be exposed, and that her husband will also be killed. At 3: 50 in the morning, I decided to call the police.

Because of gambling, Tomoto Ichiro caused his company to be on the verge of bankruptcy, and his employees could not be paid, so he thought of his classmate Matsumoto Mountain because they had a good relationship. Under the soft touch of TomotoIchiro, Matsumoto agreed to help him and the vice president in charge of medical equipment procurement in his hospital, namely Yuanye. Thanks to Matsumoto's efforts, Tomoto signed a $70 million purchase contract with Yuanye and received an advance payment of $30 million. However, Tomoto Ichiro, who got the advance payment, did not fulfill the contract to produce medical devices, but chose to pin his hopes of turning over on gambling. In an underground gambling in June, Tomotoro lost 30 million yuan and his last hope of turning over. Because he was afraid of being urged by his creditors, Tomoto Ichiro planned to flee abroad, but because he owed a bank loan, he was restricted from traveling and had to hide in Osaka, but he was finally found by Yuanye in Orange River.

The key evidence to exclude Tomoto Ichiro:

1. tomomoto Ichiro can't leave the basement;

2. Tomoto Ichiro escaped and had no money;

3. Lack of motivation;

No fingerprints were found on the victim's coat.

Since last semester, Miyamoto Yoshinori has been crushed by vilen of Orange River, and all kinds of competitions are behind vilen of Orange River, which makes Miyamoto Yoshinori jealous of vilen of Orange River. But what really brought their relationship to a freezing point was that his father died on the heart operating table in vilen, Orange River. Although the medical malpractice certificate given by the dean said that it was caused by the patient's own disease, Miyamoto Yoshinori still thought that it must have been forged by the hospital to cover up vilen's surgical mistake. In order to get the truth and expose Yuanye's crime, Miyamoto had to pretend to agree with the medical malpractice appraisal given by the dean. This presidential election, Miyamoto Jifan thinks, is the best opportunity to find out the truth. As long as he becomes the new director of the hospital, he has the right to retrieve the surgical records of that year. That's why vilen, who has always been unconvinced by Orange River, promised to use 30 million yuan for the dean.

The key evidence to exclude Miyamoto Yoshinori:

1. Tomoto Ichiro's testimony did not mention Miyamoto Yoshio and the sound of breaking the glass;

2. Leave the cash at the scene, your fingerprints are in the box;

3. The shoes are not cleaned;

There is no fingerprint of Miyamoto on the coat of the deceased.

Pure products are sensitive to light. When exposed to light, it will react with oxygen in the air and gradually decompose to produce highly toxic phosgene and hydrogen chloride. 0.6%- 1% ethanol can be added as stabilizer. Can be mixed with ethanol, benzene, ether, petroleum ether, carbon tetrachloride, carbon disulfide, oil, etc. , 25 degrees; C 1 ml is dissolved in 200ml of water. The relative density is 1.4840. Freezing point -63.5 degrees; C. Boiling point 6 1-62 degrees; C. The refractive index is 1.4476. Low toxicity, LD50 1 194mg/kg. It's very narcotic. It may also cause cancer.

* Luminol reaction: Luminol, or luminol and photosensitizer, is a general luminous chemical reagent, which will emit striking blue light when mixed with appropriate oxidant. It is a white to light yellow crystal, soluble in water and most organic polar solvents. In forensic medicine, luminol is used to detect trace blood in crime scene, and in biology, luminol is used to detect whether copper, iron and cyanide exist in cells.

* Fe3O4: Fe3O4, chemical formula. Alias iron oxide black, magnet, magnet and black iron are all magnetic black crystals, so they are also called magnetic iron oxide. Can't be read as ldquo ferrous metal; Or ldquo iron element rdquoFe2 is not a mixture of iron oxide and ferrous oxide, but can be approximately considered as a compound of ferrous oxide and ferric oxide. This substance is soluble in acid, but insoluble in water, alkali and organic solvents, such as ethanol and ether. Natural ferroferric oxide is insoluble in acid, and it is easily oxidized into iron oxide in air in wet state. Usually used as pigment and polishing agent, it can also be used to make recording tapes and telecommunications equipment.

Blood spatter: Also known as blood spatter, it is formed when blood collides, hits and scatters around. It is common for a criminal suspect to repeatedly hit the victim with a blunt instrument. At this time, the spilled blood is often mixed with spilled blood, which is usually left by the victim, as shown in the following figure:

* Drop of blood. The blood volume is mostly 0.05-0.5ml, and the shape is directly related to the angle when the blood contacts the carrier. Drop of blood can reflect the height and direction of drop of blood. If Shangluo-shaped blood is also found outside the central scene where the body is located, it can be suggested that the criminal is also damaged or stained with blood. As shown in the figure below:

* Wipe-like blood: the shape is extremely irregular, which is more common when the victim is injured and moved or the body is dragged and moved.
