Why didn't the police dog find the case of killing his wife in Hangzhou?

Why didn't the police dog find out about the wife murder in Hangzhou?

there are basically two possibilities for this problem.

the first possibility is that a well-trained police dog can't miss this case. In fact, it has already been discovered.

The police lied that the police dog search was fruitless, and the search in the building was fruitless. In fact, this is the cleverness of the police.

This Xu Moumou thinks that the planning is very thorough, and the police can't find any evidence, so they have to give up. In fact, from the beginning, the police found doubts from Xu Moumou's abnormal words and deeds, and inferred that the lady was probably killed, and the murderer was Xu Moumou, the pillow person. However, in order not to startle the snake, the police are deliberately busy, showing a very unprofessional and clueless appearance, which is equivalent to giving Xu a shot of stimulants, then deploying forces to step up their work behind the scenes and observing Xu's reaction. As a result, Xu Moumou is still claiming his unreliable logic. As a result, in silence, the police found the blood reaction in Xu's house, the traces of careful cleaning, the problem of water consumption, and the traces of toilet disassembly. After passing through the septic tank, I found the body fragments, and combined with other evidence, I locked Xu Moumou as the culprit.

The second possibility is that Xu has certain anti-reconnaissance ability, and used a lot of things that interfered with the police dog's search at the crime scene, such as wind oil, detergent, gasoline and diesel, which made the police dog unable to make an accurate judgment.

personally, I think the first one is probably bigger.

Therefore, whether it is news released by the police or media reports, the real suspects are often paralyzed and gradually exposed through the truth and falsehood. The case of killing his wife in Hangzhou, the "Goldbach conjecture" of the police dog's sense of smell failure.

After Xu dehumanized his wife, the police searched with police dogs, but found the victim in a septic tank in the community, and finally locked the real murderer.

In the past 2 days, why didn't the police dog find evidence of Xu's murder?

It is reasonable to say that Xu committed a crime in a small room of more than 5 square meters, which will leave clues, especially the smell of the victim. People's sense of smell is limited, so they can't solve crimes by smelling. But why do police dogs with strict training fail to smell?

The police dog is an animal with high nerve activity function, and its ability to distinguish smells is thousands of times higher than ours. After strict training, the police dog can undertake the tasks of tracking, identifying and searching drugs and explosives.

but in this case, the role of police dogs in solving crimes seems to be absent. Let's make a Goldbach conjecture with our brains wide open. There may be the following situations:

First, a police dog who performs a crime-solving task may just get sick when he goes out to the police, and his sense of smell may fail. This is just like when we humans have a cold, it is a truth that our nose can't smell. Dogs are also animals, and naturally we will catch a cold.

Second, Xu, the perpetrator, has skillful killing skills. He has worked in a duck farm for several years, and killing ducks is his own business. He shaves his hair to remove fishy smell, cuts open his belly, and eliminates odor. He is familiar with a series of actions and rarely leaves traces.

Third, on the day of Xu's crime, the water meter at home showed that 2 tons of water was used a day, which greatly exceeded the water consumption of normal people. Water can extinguish fire and eliminate odor, and the victim's odor was washed away by water without a trace.

Fourth, Xu didn't report the crime to the police until more than 3 hours later. For such a long time, he could use the methods of window ventilation, air conditioning ventilation and electric fan exhaust to eliminate the smell of the victim without leaving any trace, which made the dog helpless.

Fifth, the police may have found something when searching for the police dog, but the police didn't announce it in order not to startle the police and obtain more solid evidence. It was not until the human tissue of the victim was found in the septic tank that the suspect Xu was determined.

But this is unlikely. In the past 2 days, people all over the country have been paying attention to this case. If a police dog finds it, the police should announce the case to the public at the first time.

The above is just my guess. Of these five points, the last one seems to be the least likely, and the most likely one is the first four. I will answer here and share it with the masses who eat melons.

As the saying goes, the French Open is long and sparse.

Although the police dog didn't find Xu's wife-killing case in Hangzhou, he still couldn't escape the police's rigorous and meticulous work in solving the case, and the law will make a serious judgment on this cruel wife-killing criminal.

According to common sense, police dogs have a very sensitive sense of smell. Xu committed a crime and killed people in a house of more than 5 square meters, which will leave clues, especially the smell of the victim. People's sense of smell is limited, so they can't solve crimes by smelling. But why do police dogs with strict training fail to smell?

I think the sense of smell of police dogs is out of order for the following two reasons.

As we all know, the police dog is a kind of dog with high nerve activity. It has a strong ability to distinguish smells, which is thousands of times higher than that of human beings. Especially, police dogs who have been strictly trained can undertake the tasks of tracking, identifying and searching drugs and explosives. In many cases, police dogs have indeed found many suspicious situations. However, at the age of coming to Hangzhou this time, Jiulongquan didn't smell the smell.

First, the suspect handled the scene too cleanly, leaving no peculiar smell.

This murder of his wife and dismemberment by Xu was premeditated. He must have thought of this in advance and knew that the police dog's nose was very sensitive. If he is smelled by a police dog or found by the police, he will be exposed. Therefore, after doing the case, he made great efforts to remove the odor.

The employees of the supermarket found that Xu went to the supermarket to buy band-aid and cleaning essence from July 6th to July 7th, and these cleaning essence were undoubtedly prepared for clearing the crime scene. Cleaning essence has super cleaning function. The criminal suspect washed the crime scene many times. Under the action of chemical cleaning agent, there is no trace left at the scene. Xu will also think of other methods, such as window ventilation.

Second, when Xu did the case, he spread a plastic film on the ground. He thought of this in advance, how can he eliminate the trace?

If Xu has laid a plastic film in advance, he will roll up the film after committing the crime, then put it in a small bag, take it out and throw it away in a watertight way, so that no one will find it.

Xu did the work of slaughtering ducks. Although the human body and ducks are different in size, some body structures are basically the same, so he is very skilled in decomposing corpses. In addition, his tools for committing crimes must be very sharp.

If Xu laid a layer of plastic film on the crime scene in advance, then there will definitely not be much dirty things left at the scene, and after washing with detergent, there will be basically no odor.

Besides, after the incident, the police secretly checked Xu's water meter. He used two tons of water after July 6th. What were these two glasses of water used for? Must be flushing the crime scene. In this way, there will be no peculiar smell, and police dogs will not find it when they come.

In the case of killing his wife in Hangzhou, the police dog didn't find any peculiar smell in the suspect's house, which is really puzzling. I think the biggest possibility is that the criminal laid a plastic film when he committed the crime. If he hadn't covered this plastic film, even if he treated it cleanly, it would leave a little odor. Even if he used detergent and used a lot of water to flush something, he was not at ease. But the plastic film is different. We all know that plastic film is impermeable to water.

This Xu Moumou didn't report the crime until 3 hours later. He is deliberately stalling for time, so that the smell of the house is clean, and when the police come to the house, they can't find it. If she hadn't come to the women's unit, she would have called to ask why she didn't go to work. Xu wouldn't have reported the case yet, and he wanted to delay the time and let the odor at home disappear completely.

However, Xu did not expect that the water meter in his house exposed his suspicion of committing a crime, and the justice of heaven was long, sparse and not leaking, and he failed to escape the punishment of the law.

Personal opinion

The biggest possibility is that it was discovered at that time, but in order not to alarm the suspect, an illusory smoke bomb was put to let the suspect relax his vigilance, and then he went further to find evidence and arrested the suspect in one step!

In fact, let alone the police, even the people who eat melons will suspect that their husbands are the biggest suspects at the first reaction. In this case, before there is conclusive evidence to bring the suspect to justice, secrecy is the best way.

An article on the Internet reveals that Xu Moumou has cultivated duck flocks, including fish meal sales, and he has a set of skillful operation routines on how to depilate ducks, gut them, remove fishy smell, and make whole fish into fish powder.

due to family conflicts, Xu moumou laid hands on the person at the bedside, and used the above-mentioned relevant knowledge to dismember Ms. Lai. She cut the soft tissues of the human body, such as flesh and viscera, into pieces, passed through the sewer, and was rushed into septic tanks, bones and other tissues that were not easy to smash, and was taken out and discarded.

After the crime was completed, Xu took a window to take a breath, and the toilet where the crime was committed was treated with disinfectant and other deodorizing treatments, leaving no traces of the crime. As time passed, the human body odor left by the lady who came to the bathroom was already exhausted.

Even though police dogs are professionally trained, their sense of smell is very sensitive, which is many times higher than that of human noses. However, except for the lady's body odor in the bed, the quilt and the clothes worn by the lady in the bedroom, police dogs really failed to smell the lady's body odor in the bathroom where Xu was dismembered.

On the Internet, it was said that police dogs smelled the smell of Ms. Lai in the bathroom, but the police didn't startle her. This may not be true. If the police took the lead in locking the septic tank, it would be impossible to mobilize the police to inspect the manhole and nearby rivers in the community. It was not until July 23 that the sewage truck was transferred to take care of the septic tank in Ms. Lai's unit.

Through the washing and screening of 38 cars' excrement collected by the task force, it was found that there were suspected human tissues. Finally, after DNA comparison, it was determined that the human tissues belonged to Ms. Lai, and her husband Xu Moumou was criminally detained.

In addition, when the police visited the bathroom at the beginning, they didn't find anything unusual, so they may have really neglected that the glass glue at the bottom of the toilet in the bathroom was newly sealed.

afterwards, there was a broken foam structure of human soft tissue in the septic tank. It was confirmed by DNA comparison that it was Ms. Lai, and it was only after Xu was suspected of committing a major crime that this phenomenon was discovered in the bathroom.

The police detected that on the day when Ms. Lai disappeared, the consumption of tap water in Xu's house was 2 tons, which is definitely an abnormal phenomenon. It is estimated that the police also focused on investigating the residents in the building where Ms. Lai lived. Every household's storage room, wardrobe, refrigerator, etc. were all checked, and all the corridors, basements, corners of the roof, elevator shafts, flues, ventilation pipes and other hidden parts were searched, and no trace of Ms. Lai was found.

After all, Ms. Lai has been confirmed that she has not left Sanbao Beiyuan Community since she returned home on July 4th. It is impossible for a living person to be in into thin air inexplicably. The police must live to see people and die to see corpses. It is a pity that Ms. Lai only has fragmented human soft tissues. The perpetrator of this case is very cruel, which has exceeded the bottom line of human imagination. Xu Moumou has a very strong psychological resistance and a certain anti-reconnaissance ability. In the police and the media,

so is this stupid ratio! Just to give my son a house is like this!

the wife is the one who keeps the most company, and none of the children are. He made it himself, hurting others and himself. What a jerk and devil. < P > The smell is everywhere, and the police dogs are scared. How do you call it?

Actually, I've thought deeply about this issue, but in the end, according to the brainstorming of netizens, I'll sum it up:

1. Xu's technique is really brilliant.

If he intends to get rid of the smell of blood, he will definitely try various ways to cover it up, such as soaking it in diluted alum water, or washing powder and soap for home use, and washing it repeatedly with water several times, so that he can get it from the water consumption of Xu that day.

2. The police deliberately said that the police dog didn't smell it, so as to let the murderer off guard.

We all know that police dogs are trained professionally. If the police deliberately keep the police dog quiet, of course, they can do it. Maybe the police also suspected that Xu was the murderer, just to let Xu off guard and solve the case better.

3. Just kidding, the police dog didn't work hard.

This is not what I said. This can't be taken seriously. You know, in order to solve this case, a lot of police dogs were dispatched, and it's okay that one didn't work. It's too exaggerated to do so much.

The above is the reason why the police dog didn't find it. If there are any left, please add them.

As far as I can guess, there are two reasons:

First, it is too thorough and clean. It is estimated that Xu's dismemberment was carried out in the bathroom. The floor and walls of the bathroom should be covered with tiles. Even if it is stained with blood or dirt, it is easier to clean, and the bathroom space is narrow, so it is not difficult to clean thoroughly. After committing a crime, Xu once went to a nearby supermarket to buy detergent. After committing the crime, he must have carried out arduous cleaning of the bathroom for n times, and it is normal for the police dog's nose to smell nothing.

Second, Xu used some special bead treatment method. Xu has been planning to kill his wife for a long time, and he must have a plan for the police dog to come to the door to investigate the case. Therefore, he must have come up with a coup in advance to deal with the long-standing countermeasures. Sure enough, the police dog failed.

but cleverness is mistaken by cleverness! Xu, a demon on earth, will be severely punished by law!

The murder of a wife by Xu Moumou in Hangzhou has been planned for a long time. You want him to find the shredder and hold his daughter away. When her daughter is not at home, she always commits crimes.

All his actions are planned by Xu for a long time, and he has the ability of anti-reconnaissance. Therefore, if the police can find the body, it will prove that Mr. Xu's anti-reconnaissance ability has failed.

According to Mr. Xu's practice, he has been planning to get this property for more than ten years. At that time, he has already laid a premeditation since he asked his wife for a divorce, used domestic violence against his ex-wife, and forced her to divorce.

That's why he said that his wife's IQ is not high, which is why she knew that she wanted this woman to kill her for money. This woman was not alert at all, so Xu Moumou was sarcastic and had no IQ.

Xu moumou naturally thinks that he has a high IQ, so his high IQ and anti-reconnaissance ability can't be found by the police and naturally won't be left to the police dogs.

It's obvious.
