Chapter 817 Kill him!
Chapter 817 Kill him! (4000)
That afternoon, after learning about the two people's prank, Matayoshi Kazuo came up with this murder method using a "fire trigger" in his mind.
His preparation was very simple, he just went to the supermarket and bought a small oxygen bottle.
This thing is not difficult to buy. Before the financial crisis in the 1990s, many people would buy this oxygen inhaler. It was considered a popular thing in that era.
Although this thing is no longer popular after the crisis, it has not completely disappeared. It is still sold in major supermarkets.
After buying the necessary props, Kazuo Matayoshi drove directly to the company's underground parking lot and waited patiently in the car.
As time passed, Matayoshi Kazuo soon discovered the figure of Chieko Miyama at the back door of the underground parking lot.
He knew the prank between the two was about to begin.
Sure enough, not long after, he heard the conversation between Chieko Miyama and Takegawa.
Soon, Toshio Takegawa walked in, and the door behind him automatically closed and locked.
Seeing the success of Chieko Miyama's prank, Kazuo Matayoshi also started his own plan.
He opened the car door as Tomo Takegawa yelled at the front door.
The cigarette was also left behind at that time.
Takegawa Toshio seemed to be in a panic, and he didn't notice him until this moment.
It wasn't until he activated the "fire trigger" button and the alarm started in the underground garage that Toshio Takegawa noticed his presence.
After a brief daze, Takegawa Toshio quickly realized what Matayoshi Kazuo was planning.
He ran towards Kazuo Matayoshi's car like crazy and wanted to ask for a deposit, but Kazuo Matayoshi also ran towards the car.
But just as Kazuo Matayoshi was about to get in the car, Toshio Takekawa also pounced on him.
The two of them struggled in the parking lot, but Toshio Takegawa was old after all, so how could he be the opponent of Kazuo Matayoshi, a man in his early thirties.
Soon, Matayoshi Kazuo broke away from Takegawa Toshio's grasp on his right arm, but the other party struggled so hard that his arm was accidentally scratched by the other party.
But that was all. Afterwards, Toshio Takegawa didn't cause him any more trouble. He directly pushed him aside, immediately closed the car door and put on the respirator on the oxygen bottle.
At this time, the fire extinguishing device on the ceiling had begun to spray a large amount of carbon dioxide gas, and Takegawa Toshio's desperate howl was completely silenced by the spray of white smoke.
The entire underground parking lot fell into silence. After a while, Kazuo Matayoshi got out of the car with an oxygen bottle in hand and looked at Takekawa's body. Then he opened the front door with the remote control of the electronic garage door and drove away from the crime scene.
Yes, he has a remote control. After all, he was an employee of this company two days ago, so he naturally has the key to the iron rolling door of the underground parking lot.
Although he left his job, the key to the remote control had not been returned yet, which made it easier for him to complete the ruse.
When it was discovered, everyone would definitely think that it was because Takekawa, who was trapped in the underground parking lot, was too anxious and pressed the fire alarm while out of his mind, causing his own death.
At that time, this will become an accident, and he will be able to get away with completing a "complete murder".
"If they weren't so troubled, everything would have been treated as an accident." Kazuo Matayoshi growled in a hoarse voice, "It's all them."
"That's enough!" Tang Ze said in a stern tone: "Have you ever thought of looking for the reason from yourself for the guy who refuses to repent?"
After being scolded by Karasawa, Matayoshi's expression kept changing and he could only bow his head and remain silent.
When things got to this point, there was actually no need to say more. After Kazuo Matayoshi explained the entire incident, Karasawa had someone take him into custody.
Tangze didn't bother to say anything to the guy who refused to repent and blamed others until the end.
After leaving the interrogation room, Officer Memu came over and said, "Thank you for your hard work. This case really helped a lot. This is also the debut of "Kesouyan"."
"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 the "Kesouyan", to reform and optimize the search link."
"Looking forward to your performance." Officer Megure patted Tang Ze on the shoulder: "Okay, you go ahead and I'll handle the follow-up of the case."
"Then I'll leave first." Tangze nodded and said hello to Takagi, then drove directly to get off work.
Back home, Ayako had already prepared dinner. After Karasawa finished eating, he lazily piled on the sofa and clicked on the panel to check the rewards.
[Invisible suffocation murder case]
[Congratulations to the host for obtaining Physics (3 years)]
Evaluation: The "Kesouyan" founded by you has brought more changes to the world. With the advancement of science and 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 hidden, which is destined to be a long battle.
Somehow you have been favored by fate!
Seeing this, Tang Ze couldn't help but raise his eyebrows, thoughts flashing through 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 that he is a consultant for "Kesouyan", it would be good to have more knowledge in related fields.
After all, for scientific researchers, even if you are their boss, if you don’t understand the relevant field at all, they will not be particularly impressed by you.
This is also a common mentality among academics. After all, if I tell you that you don’t understand, then what else is there to say?
At least you have to be able to listen and understand what the other person is saying, then at least you have the basic language.
Moreover, Karasawa took charge of "Kesouyan" not just to establish this department, his mission was to integrate "Kesouyan" into the existing search system.
To put it simply, it is to use machine assistance to let criminals learn to use science and high technology to better solve cases.
The integration of the two parties naturally requires both parties to work together. Simply standing on one side will definitely be biased.
Tangze happened to know a little bit about both parties, so he was naturally the best person to lead the integration of the new system into the existing search system.
And this case is obviously a good start.
The puzzling case of the "Invisible Suffocation Case" was solved with the help of the "Kesouyan", which can be regarded as the official emergence of this newly established department.
Tang Ze also believes that this case will be regarded as a case and become a must-read material for the upper-level bosses, and it will also let them understand the role that the power of science can play.
Even if it's just a "picture of a leopard", people can still see the effect.
In some bizarre death cases, the actual difficulty is "not understanding".
And "Kesouyan" is the place to analyze these bizarre cases and find the root causes.
And when the puzzling method becomes clear, the case is actually not that far away from being solved.
The existence of "Kesouyan" has given a clear and intuitive understanding of difficult events that were originally invisible and confusing. Although it is still an example, this makes people see the possibility of solving difficult cases more easily.
Taking advantage of this opportunity, Tangze took the next step.
A decision that is simple to implement, yet easily results in results.
There is no way, after all, the current "Kesouyan" is still a start-up. Although it has begun to emerge, it is not an isolated case.
If we cannot produce phased results, I am afraid that we will not receive stronger support in the future, which will not be conducive to the future development of the department.
This is normal. After all, there are many agencies under the Metropolitan Police Department, and everyone is fighting for funds. If you have more, other agencies will naturally have less.
Since Tang Ze took the lead in the "science search and research", he naturally did not want his "babies" to be short of food.
Moreover, "Kesouyan" is different from ordinary departments in that it requires a lot of high-end equipment.
These funds have not been approved before. Obviously the upper-level bosses are still waiting and watching, so Tang Ze wants to show the results and let them make a decision.
Not to mention that this will allow "Kesouyan" to develop, but at least it can formally set up the department.
The current "Kesouyan" equipment is all old equipment from the original research institute, and many of them are used for research and cannot play a role in searches.
"If a worker wants to do his job well, he must first sharpen his 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 analytical and testing equipment.
Moreover, Karasawa 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 in Meilijian has been rising like crazy recently.
In Tang Ze's view, this is a very bad sign, and if an outbreak occurs, this area will definitely be affected.
Tang Ze doesn't care about the others. If the funds originally expected to be allocated to "Kesouyan" are intercepted by the higher-ups, then Tang Ze will really cry his eyes out.
Therefore, we must produce results as soon as possible to lay the foundation for the development of "Kesouyan".
Tang Ze thought that the most suitable entry point was to introduce polygraphs.
I believe that many people are familiar with this thing and have some understanding of it.
Although polygraphs in this era are very rudimentary, they are actually very useful.
To put it simply, it is to detect and determine whether you are lying based on your physiological reactions and other conditions.
Moreover, with the introduction of lie detectors, it is easy to see the results.
After all, in the battle of wits and courage with the prisoner, "lies" can be said to run through the entire process.
Of course, there must be restrictions. For some people who are simply suspicious, I am afraid we can only ask the other party to cooperate in testing.
Just like the "non-coercive interrogations" they often do in criminal cases, it is not impossible to bring the suspect back to the Metropolitan Police Department without a search warrant, but it requires the other party's consent to cooperate, and the other party also has the right to refuse.
Of course, if you have a search warrant, everything will be easy, and it will prove that you are a serious suspect. Then whether it is an arrest or the use of a polygraph, the Metropolitan Police Department has the right to do so.
But no matter what, if lie detectors can be introduced, this will definitely be a visible change.
As a mystery fan in his previous life, Tang Ze was actually very aware of the power of lie detectors.
Generally, using a lie detector is simple.
At the beginning, 9 cards from one to nine will be prepared, and then the tester will be asked to randomly select one card from the nine cards marked with numbers.
Then starting from number 1, one by one asks "Is the card you see "X"?" Repeatedly.
Use this as a template to introduce the problem into information that only the murderer knows, such as the color of the deceased's clothes and what kind of similar weapon he was killed with.
If the subject is really a prisoner, then he must know what he has done.
When he gets the correct answer, if he chooses to lie, his physiological reaction will be detected and fluctuate.
This may seem like magic, but it is actually based on a person's blood pressure, pulse, breathing and other physiological reactions when the person is lying.
Of course, lie detectors are not omnipotent. There are still people who can deceive the machine after professional training.
It's just that people like that are too rare to see. They only target ordinary criminals, not professional espionage personnel.
Tangze's choice of polygraph test is actually a good entry point.
First of all, polygraphs are relatively cheap equipment compared to those expensive machines, and they are simple to operate and do not require high-end professional technicians.
Cheap means easy to spread and can be used on a large scale.
More importantly, it's easy to get results and it's very straightforward.
The lie detector is actually very useful for ordinary people. Although there will be a "pre-examination" before starting the test, many people can't pass this first level.
When you deny the playing card you saw, the machine directly determines that you lied. Many suspects will choose to give up resistance at this stage and confess everything.
With this, the results are obvious.
If nothing else, at least it can improve efficiency in many cases.
For example, against those thieves, this thing is definitely a killer weapon.
Those thieves are all habitual offenders, but the crimes they commit are not serious. They have been in there for a few years and then go out and continue to commit crimes. Many of them are old people and never tell the truth.
After a theft occurs, they are the first people the police investigate.
But you can't believe what they say, so you can only investigate slowly.
But it would be much more convenient if you had a lie detector. You really have no choice to hide it under the test.
For habitual thieves, this thing is a big deterrent and prevents them from committing the same crime again.
After all, they have already registered with the Yamen, and they can also test whether you are lying or not, and whether you are panicking or not.
After making up his mind, Tangze stood up and took out his phone to call Mr. Saitama to let him know his plans first.
And with the support of Mr. Saitama, I believe that we will soon be able to convince the higher-ups to implement this plan.
Tang Ze is looking forward to this very much.
