The master of crime's answer to sin

Sin answer:

Fang Linyou (Chef)

Analysis of criminal thought;

According to the traces of the scene and the clues of the suspect, the police deduced the video record played by the murderer and successfully restored the incident. Subsequently, the recent consumption records of each suspect were transferred. After careful inspection, it was found that Fang Lin had recently purchased iodine tablets and 30% concentrated ammonia water, and the police immediately arrested Fang Lin. After a long trial, Fang Linyou finally admitted his criminal facts. Chen died because of ineffective rescue.

Breakthrough point of the case: trace reasoning is restored to the scene, whether two simultaneous cases are related and whether they can be merged.

Because Chen came back from the city after receiving the information of the deceased Wang Anrui (at the same time, through the time of death of the deceased and the unanswered information), it can be concluded that Chen died indirectly because of the deceased Wang Anrui. From this point of view, the two cases are enough to merge, and the murderer may be the same person.

1. According to the clues of the deceased, it can be inferred that the deceased Wang Anrui killed Chen first, and then Chen had an accident. Wang Anrui's suspicion is that there is a key in the warehouse, and there is a shoe print with the same pattern of the deceased Wang Anrui not far from the door of the warehouse. Wang Anrui's attic window has slingshot marks.

Wang Anrui's doubts are: a cup of water containing sodium chloride; The floor has been wiped; The barefoot shoes of the deceased were messy; It is found that the indoor temperature is only 15 degrees Celsius, and the temperature in Shenzhen in June 1 1 is 23 degrees Celsius, which is too different from the outdoor temperature. The electricity meter jumped abnormally overnight, and there was a cold air circulation system at home. The combination of cold air circulation system and watt-hour meter can explain that it should have been on for a long time, not long ago. It can be inferred from the combination of the two that someone turned on the cold air circulation system for a long time and turned it off not long ago, which lowered the indoor temperature and caused the instrument to jump. The purpose of this is only one possibility-to prolong the time of death. That is, Wang Anrui was a murder, not an accident. To sum up, Wang Anrui's suspicion of arson can be ruled out. Cigarette butts: First of all, a heavy smoker who has been smoking for 20 years can't smoke only four cigarettes a day. However, according to the fact that the garbage can was not cleaned and four cigarette butts were found, there were several cigarette butts at the scene of Chen's death, indicating that the source of these cigarette butts is probably Wang Anrui.

The murderer put the cigarette butts used by Wang Anrui at Chen's scene to frame the crime. In addition, if it is really suicide, you don't have to wipe your fingerprints clean, or someone else has a key.

2. Chen crime scene: ammonia nitrogen hexaiodide was found; There are some footprints of Wang Anrui not far away; There are cracked stone fragments; The window can see the window of Wang Anrui's attic.

Nitrogen hexamine triiodide can be directly identified as the cause of fire. A charred and cracked stone was also found at the scene. You can see Wang Anrui's attic through the window, and a slingshot is found in Wang Anrui's attic. Broken stones and slingshots can show that the murderer can shoot stones at the prearranged nitrogen hexamethylene triiodide and then cause an explosion, which can cause a fire because it is located in the silk warehouse.

Through the above-mentioned fire-fighting methods, it can be concluded that the murderer has accurate shooting ability and good eyesight. A footprint was found at the scene, with uneven soil distribution, less soil at the edges and toes, and the center of gravity in the middle. It can be inferred that shoes don't fit, that is, small feet wear big shoes. In addition, there is no dust in the left window of Wang Anrui's attic. At the same time, the impression of the left slingshot bow shows that the murderer may press the wall with his left hand and pull the bow with his right hand, so it can be concluded that the murderer is right-handed or hands.

Based on the above conditions, the murderer should be an acquaintance; Accurate shooting ability; Good eyesight; Height is shorter than Wang Anrui; Right-handed or both hands.

Suspicious information analysis is as follows:

1. Zhou Youjun: Zhou Youjun often plays CS, survives in the wild and has accurate shooting ability; There is no problem with vision; By putting the used computer on the left bedside table and waiting for clues, it can be inferred that his left hand is dominant. Because the murderer may also be a two-handed person, he is suspected. However, his height is 175cm, which is similar to that of Wang Anrui, and the shoe size gap may be very small (the footprints don't match), so the suspicion of committing crimes is reduced. In terms of motivation, a month ago, it was found that his girlfriend of two years had a bad relationship with Chen, so they clashed with Chen, and they were detained by the police for fighting. However, what makes army tour even more angry is that his girlfriend has not separated from Chen, but has become more intimate. He suddenly became angry and decided to follow Chen, trying to photograph his weakness and threaten him. Because he has just moved here and is not familiar with the people around him, it can be inferred from his confession that there are few social relations near him, so it can be concluded that there are no accomplices. Because the traces of the crime scene and Zhou's information can't coincide, the hypothesis that he killed people is not established.

2. Liu Xiu: Liu Xiu is a writer who found a lot of manuscript paper-often writing, and found a cocoon in the middle finger of his right hand-which can be inferred as right-handed; Height 170cm, taller than Wang Anrui, and feet smaller than Wang Anrui, all of which meet the characteristics of the murderer. But because there are dents on both sides of the nose, you can push it out and wear glasses. Rubbing eyes and eyelids can prompt myopia and overuse of eyes; Levofloxacin eye drops and conjunctivitis further confirm their poor eyesight-conjunctivitis patients have foreign body sensation in their eyes, blink from time to time, and at the same time their eyes feel itchy, so they can't concentrate on one place to shoot accurately, which is not in line with the characteristics of the murderer. In terms of motivation, a year ago, his friend published an article about the harm of native silk to human health, which was slandered by Chen and damaged his reputation, and finally he died of depression. So he decided to move to a villa near the warehouse on the outskirts of Liuyang to collect evidence and exonerate his friends. According to the above analysis, Liu Xiu can be ruled out.

3. Fang Linyou: Fang Lin's height 170cm, shorter than the deceased, conforms to the characteristics of the murderer; He is a cook, and his right hand is thicker than his left. It can be inferred that he is left-handed. (Chefs usually copy vegetables by hand and knock on the pot by hand, which leads to more developed hand muscles and thicker hands. However, left-handed people can also become two hands the day after tomorrow, and the chef will knock on the pot with the other hand, and the right hand will be more powerful. The information implies that everyone in the club has a high IQ, and there is a sentence in the information, "However, the only rule is to keep the password of the activity content confidential", which can be inferred as a password.

4. password: take the first letter of each sentence: d (big), a (ang), r (natural), t (group), s (who) = darts, that is, darts. Because this is a professional member group extracted from the data, it can be concluded that Fang Linyou is a professional member of the darts club, and his shooting ability is accurate, which conforms to the characteristics of the murderer. To sum up, it can be concluded that Fang Lin is the most suspected criminal.
