Detectives of Detective World

That afternoon, after learning of the two people's pranks, this murder method with the help of a "fire trigger" appeared in Yuji and Fu's mind.

The preparation he made was very simple, just went to the supermarket and bought a small bottle of oxygen.

This thing is not difficult to buy. Before the financial crisis in the 1990s, many people would buy this oxygen inhalation device. It was a popular thing at that time.

Although this thing is no longer popular after the crisis, it has not disappeared completely, and big supermarkets will still sell it.

After buying the necessary props, Yuji and Fu drove directly to the company's underground parking lot and waited patiently in the car.

With the passage of time, Yuji and Fu soon found Chieko Miyama at the back door of the underground parking lot.

He knew that their prank was about to start.

Sure enough, after a while, he heard the conversation between Miyama Chieko and Takekawa.

Soon, Toshio Takekawa walked in, and the door behind him was automatically closed and locked.

Seeing the success of Miyama Chieko's prank, Yuji and Fu also started their own plan.

He opened the car door while Toshio Takekawa was yelling at the front door.

And cigarettes were thrown away at that time.

It seems that Toshio Takekawa was in a panic and hadn't found him until this time.

It was not until he activated the "fire trigger" button and the underground garage started to sound the alarm that Toshio Takekawa noticed his presence.

After being stunned for a while, Takekawa Toshio quickly realized Kazuo Yuyoshi's plan.

He ran to Yuji and Fu's car like crazy and wanted to save, and Ji and Fu also ran to the car.

But just as Yuyoshi and his husband were about to get into the car, the life-and-death potential broke out, and Toshio Takekawa also pounced on him.

The two scuffled in the parking lot, but Toshio Takekawa was old after all, so how could he be the opponent of a man in his early thirties, Kazuo Yukichi.

Soon, Yuji and Fu broke free from Takekawa Toshio and grabbed his right arm, but the other party struggled so hard that his arm was accidentally scratched by the other party.

But that's all. After that, Toshio Takekawa didn't cause him any more trouble. He pushed it aside and immediately closed the car door and took the exhaler on the oxygen cylinder.

At this time, the fire extinguishing device on the ceiling had already started spraying a large amount of carbon dioxide gas, and Takekawa Toshio howled with despair, and went silent under the spray of white smoke.

The entire underground parking lot fell into silence. After a while, Ji and Fu got out of the car with an oxygen bottle in hand and looked at Zhuchuan's body. Then, he opened the front door with the remote control of the electronic garage door and drove away from the crime scene.

That's right, he has a remote control. After all, he was an employee of this company two days ago, so he naturally has the iron roll door key in the underground parking lot.

Although he left his post, the key of the remote control had not been returned in time, which also facilitated him to complete the trick.

When they found out, everyone would definitely think that it was because Zhuchuan, who was trapped in the underground parking lot, was too anxious, so he lost his mind and pressed the fire alarm, resulting in his death.

At that time, it would become an accident, and he would be able to get out of the crime and complete a "complete murder".

"If they don't have so many things...everything will be regarded as an accident..." Youji and Fu roared unwillingly and hoarsely in their voices: "It's all them..."

"Enough!" Tang Ze said coldly and sternly, "Have you never thought about finding a reason from yourself, an unrepentant guy?"

Being reprimanded by Tang Ze like this, Youji and Fu's complexion kept changing and finally they could only bow their heads and say nothing.

At this stage of the matter, there is no need to say more. After Yuji and her husband explained the whole process of the matter, Tang Ze let him be held down.

In the end, the guy who didn't repent and complained, Tang Ze was too lazy to say anything to the other party.

After leaving the interrogation room, Officer Mu Mu greeted him: "Thank you for your hard work. This case has really helped a lot. "Ke Soyan" is also its first appearance this time."

"I hope there will be better results in the future." Tang Ze said with a smile: "This is also the purpose of the establishment of "Science Research", to reform and optimize the search process."

"Looking forward to your performance." Officer Mumu patted Tang Ze on the shoulder: "Okay, you're busy first, I'll handle the follow-up of the case."

"Then I'll go first." Tang Ze nodded and said hello to Takagi, and drove straight off work.

When he got home, Ayako had already made dinner, and after Tang Ze finished eating, he sluggishly piled up on the sofa and clicked on the panel to start checking the rewards.

【Invisible suffocation murder case】

[Congratulations to the host for obtaining physics (3 years)]

Comment: The "Kesou Research" created by you has brought more changes to the world. With the advancement of technology, more difficult cases may become simpler due to the reforms you brought.

But on the other hand, high-tech crimes may also be more insidious, which is destined to be a long contest.

Somewhere in the world, you have been favored by fate!

Seeing this, Tang Ze couldn't help raising his eyebrows, and thoughts kept flashing in his mind.

First of all, the reward this time is not bad. Originally, physics was used to assist Tang Ze in judging some phenomena in the case more comprehensively.

And now he has become a consultant of "Science Research", and it is also good to have more knowledge in related fields.

After all, for a scientific researcher, even if you are his boss, if you don't understand the relevant fields at all, they won't particularly convince you.

This is also the common mentality of academics. After all, if I tell you that you don't understand, "the donkey's lips are not the horse's mouth", so what else is there to say.

At least you have to be able to understand and understand what the other party is saying, then at least you have the basic language.

Moreover, Tang Ze was in charge of "Science Research" not only for the establishment of this department, but his task was to integrate "Science Research" into the existing search system.

To put it simply, it is to use machine assistance that allows criminals to learn to use science and high technology to better solve cases.

The fusion of the two sides naturally requires the two sides to run in with each other. Simply standing on one side will definitely be biased.

Tang Ze just happened to know a little bit about both parties, so he was naturally the best candidate to lead the new system and integrate it into the existing search system.

And this case is obviously a good start.

The "invisible suffocation case", a puzzling case, was solved with the help of the power of "Science Research", which can be regarded as the official appearance of this newly established department.

Tang Ze also believes that this case will be regarded as a case and become a must-see for the upper-level bigwigs, and it will also let them understand how the power of science can play a role.

Even if it's just "peeping the leopard in the tube", it can still make people see the effect.

In some bizarre death cases, the actual difficulty is "don't understand".

And "kesouyan" is the place to analyze these bizarre cases and find the root cause.

And when the tricks that make people puzzled are clear, it is actually not far from solving the case.

The existence of "Science and Research" has given a clear and intuitive understanding of difficult events that were originally invisible and incomprehensible.

Although it is still a case, it makes people see the possibility of solving difficult cases more easily.

With this opportunity, Tang Ze started the next move.

A decision that is simple to execute, but easy to make.

No way, after all, the current "Science Research" is still a start-up, although it has begun to emerge, but it is not enough.

If there is no staged results, I am afraid that there will be no stronger support in the future, which is not conducive to the development of the future department.

This is also normal. After all, there are still many agencies under the Metropolitan Police Department, and everyone is fighting for funding. The more you have, the less other agencies will naturally be.

And since Tang Ze led the "Science Research", he naturally didn't want his "cubs" to be short of food.

And "Science Research" is different from the general department, it needs a lot of high-end equipment.

These funds have not been approved before. Obviously, the top bosses are still waiting and watching, so Tang Ze has to come up with the results and let them make a decision.

Not to mention that this will enable the development of "Science Research", but at least it can officially set up the department.

The current "Science Research" equipment is the old equipment of the original research institute, and many of them are used for research and cannot play a role in the search.

"If you want to do good work, you must first sharpen your tools." If you don't even have the most basic tools, you can't talk about future development.

The equipment that Tang Ze wants to purchase with this batch of funds is targeted and tends to be analyzed and tested.

And Tang Ze still has some sense of urgency, because the financial crisis is likely to break out.

Others don't know, but he has always attracted people's attention. Ayako also said two days ago that the stock market on Meijian's side has been rising like crazy.

In Tang Ze's view, this is a very bad omen, and if there is an outbreak, it will definitely be impressed.

Don't care about other Tang Ze, if the funds originally expected to be granted to "Science Research" are intercepted by the above people, then Tang Ze will really cry.

Therefore, it is necessary to produce results as soon as possible to lay a foundation for the development of "Science Research".

Tang Ze thought that the most suitable entry point was to introduce a polygraph.

I believe that many people are familiar with this thing, and they will know a little bit about it.

Although the polygraph of this day and age is very simple, it actually has a great effect.

To put it simply, it is to detect whether you are lying or not based on your physiological response and other conditions.

And the introduction of a lie detector makes it easy to see the results.

After all, in the process of wrestling with the prisoners, the "lie" can be said to run through the whole process.

Of course, there must be restrictions. For some people who are just suspicious, I am afraid they can only ask the other party to cooperate with them for testing.

Just like the "non-mandatory interrogation" they often do in criminals, it is not impossible to take the suspect back to the Metropolitan Police Department without a search warrant, but it requires the other party's consent and cooperation, and the other party has the right to refuse.

Of course, if you have a search warrant, everything is easy to say. It proves that you have a serious suspicion. Whether it is arresting or using a polygraph, the Metropolitan Police Department has the right to do so.

But in any case, if a polygraph can be introduced, it will definitely be a visible change.

As a reasoning fan in his previous life, Tang Ze was actually very aware of the power of the lie detector.

In general, the use of a polygraph is simple.

At the beginning, nine cards from one to nine are prepared, and then the tester is asked to randomly select one of the nine cards marked with numbers.

Then start with the number 1 and ask "Is the card you see an "X"?" Repeatedly.

Using this as a template, bring the question into information that only the murderer knows, such as the color of the deceased's clothes, and what similar weapon was used to kill it.

If the subject is really a prisoner, then he must know what he has done.

When the correct answer is reached, if he chooses to lie, the physiological response will be detected, resulting in fluctuations.

It may seem like magic, but it's actually based on a person's blood pressure, pulse, and respiration, etc., how a person's physiology responds when they lie.

Of course, the lie detector is not a panacea. After professional training, there are still people who can fool the machine.

It's just that people like that are too rare to see. They only target ordinary criminals, not professional spies~www.NovelMTL.com~ and Tang Ze's choice of a lie detector is actually a good starting point.

First of all, compared with those expensive machines, the polygraph is a cheap device, and the operation is also simple, and it does not require too high-end professional technicians.

And cheap means easy to spread and can be used on a large scale.

More importantly, it's easy to get grades, and it's straightforward.

The polygraph is actually very useful for ordinary guys. Don't look at the "pre-check" before starting the test, but many people can't pass the first level.

When you deny the poker card you saw, the machine directly judges that you lied, and many suspects will choose to give up resistance and confess everything at this stage.

With this, the effect is obvious.

If nothing else, at least in many cases it can save efficiency.

For example, to deal with those thieves, this thing is definitely a big killer.

Those thieves are repeat offenders, but the crimes they committed are not serious.

After the theft, the police are the first to investigate these people.

But you can't believe what they say, and you can only investigate slowly.

But if you have a lie detector, it will be much more convenient, you really can't choose to hide under the test.

For habitual thieves, this thing is a big deterrent, avoiding the possibility of their repeat offenses.

After all, they have already registered at the yamen, and they can still tell you whether to talk to the inspection, and you can say that you are not panicking.

After making up his mind, Tang Ze got up and took out his phone to call the big boss Saitama, and let him talk about his plans first.

And with the support of the big boss Saitama, I believe that the upper management can be persuaded to implement this plan soon.

Tang Ze was very much looking forward to this.
