Although it was confirmed that it was homicide, Tang Ze did not feel very relaxed at this moment.
Because this case is very difficult.
As for the reason, it is naturally based on the cause of Toshio Takekawa's death.
After the autopsy of Takegawa Toshio's body, no signs of suffocation caused by compression of the chest or neck, obstruction of the mouth, nose or respiratory tract were found.
In other words, Toshio Takegawa did not die from conventional killing techniques such as strangulation, strangulation, or drowning.
After ruling out these situations, there is only one possibility.
He died of suffocation due to simple lack of oxygen.
Having no symptoms is actually a symptom.
This time, there were no wounds on the surface of the corpse, and there were no strange symptoms in the body. In other words, the corpse showed signs of acidemia and loss of amino acids, so it was determined that Toshio Takegawa died of suffocation.
This is exactly in line with the human body's death from suffocation due to lack of oxygen.
But how could a person die from lack of oxygen in a place like the crime scene?
As for the speculation that you are suffocating yourself to death, it is simply a joke. Fools all know that it is impossible for people to suffocate themselves to death. The desire to survive will definitely overcome everything in the end.
Using unknown techniques to create a hypoxic situation to kill people is the most troublesome thing.
You have no idea what specific method the prisoner used to kill him. Even if you have someone to suspect after investigation, there is nothing you can do against him.
Even if you think his murderous motive is astonishing, as soon as the other person questions "How did I kill him?" you will be speechless and unable to refute it.
Ultimately, this is a matter of confidence.
Therefore, the method of killing must be clarified. This is the basis of all reasoning.
If the method of killing cannot be confirmed, then all subsequent reasoning will be as fragile as a castle in the air.
The cause of death was not confirmed, and the case was in trouble from the beginning.
After Tang Ze conveyed the news to Officer Megure, he left work directly.
There is no way, it is already late at night, and there is no way to continue the investigation by investigating Takegawa Toshio's interpersonal relationships. We can only wait until tomorrow to see if there is any progress.
But Tang Ze had a hunch that this case might be more troublesome than imagined.
After sending the body and some items on the clothes to the "Physical Evidence Inspection Section" for detailed analysis tomorrow, Tangze left the "Kesouyan".
After returning home and resting for the night, Karasawa took Naoki Uye and Takagi early the next morning to the club where the deceased Toshio Takegawa was.
After showing the criminal certificate, Tangze and the other three were led by the front desk staff to the reception room.
Karasawa winked at the two of them, and Takagi and Uye Naoki left the room.
After a moment of waiting, a man in a suit entered the meeting.
"I am the head of the General Affairs Section, and my surname is Kujo Hiro."
The man bowed slightly towards Tang Ze. After the two exchanged greetings, the other person sat down and looked at Tang Ze: "I already knew about Minister Takekawa. I was really shocked. I didn't expect..."
"I came here this time to ask about Minister Takekawa," Tangze said.
"Um...excuse me for being rude, is this a murder case?" Kujo Hiro hesitated and asked.
"No, at the moment, we can't be sure yet." Although Tang Ze has determined in his heart that there is a high probability that this is a murder case, he still needs to hide what should be concealed.
"Is that so..." Kujo Hiro nodded and said nothing more.
"Excuse me, what kind of person is Minister Takegawa?" Seeing that the other party had finished asking the question, Karasawa immediately started to get to the point.
"Well..."
Kujo Hiroshi glanced at the ground subconsciously, then pondered for a moment and said: "He has a very strong working ability, and he also takes good care of his subordinates. Everyone also admires him."
"The information we investigated before we came here showed that Minister Takegawa was sent from a bank that has dealings with your club. Is this true?" Tang Zeying confirmed the authenticity of this information.
"Yes, it is indeed the case." Kujo Hiro nodded.
"Then his existence won't make you feel embarrassed?" Karasawa glanced meaningfully at Kujo Hiro, who had an unsightly expression: "After all, he is a person sent by Party A."
"No, how could it be possible? It's nothing..." Kujo Hiro still tried to frustrate Karasawa with his words, but his guilty expression had unconsciously betrayed his inner thoughts.
Tang Ze was not too surprised by this. The senior executives of these large companies were different from the lower-level staff. When something happened, they wanted to hide it and maintain stability, and were unwilling to get into any trouble.
This is normal. After all, dead people are not very honorable. If the news spreads, it will have an impact on the company. Naturally, we should be cautious.
Of course, Tang Ze was just asking a routine question. Seeing that the other party didn't want to say more, Tang Ze didn't force him to say thank you and said goodbye to him.
When he got downstairs, Karasawa waited for a while, and then he guessed that he saw Takagi and Uye Naoki walking out of the elevator.
Now that he knew that the top executives of these companies were always eager to protect their interests, how could Tangze not make preparations.
After leading them into the company at the front desk, Karasawa asked Takagi and Uye Naoki to go inside the company to question the employees when Kujo Hiro didn't come.
The upper-level people will conceal and say polite things against their will for their own benefit, but the ordinary employees at the lower level won't worry so much.
Good is good and bad is bad. They will tell the truth more objectively.
As expected, Takagi and Naoki Uyei received completely opposite comments from Kujo Hiro when asked at the company.
According to the members, Toshio Takegawa's reputation is extremely bad.
Because he was the representative of Party A sent by the bank, his attitude was very arrogant.
Not only did he arbitrarily instruct male members to do his personal work, but he also engaged in sexual harassment when communicating with female members.
One employee couldn't bear it and had a conflict with him, so he backhandedly forced the employee to resign.
"What is the name of this employee who had a conflict with the deceased?" After listening to the reports of the two men, Tang Ze asked: "Can you find him?"
"My name is Kazuo Matayoshi, and I have already asked for his address." Takagi looked at his notebook and said.
"Find the other party and inquire. Takagi, you take him to the well. I want to go back to the science and research."
Tang Ze looked at the time: "Some of the physical evidence left yesterday should have results. I want to go back and take a look. Let's split up."
"I understand." Takagi nodded, then drove away with Naoki Kamei.
As for Karasawa, after hearing the two people leaving, he started the car and returned to the "Kesouyan".
With the advancement of technology and the times, some methods may be unimaginable, and ordinary people may not have any contact with related fields.
And "Kesouyan" is the place to solve these phenomena. Just like what his father said, "use magic to defeat magic." There will definitely be many times when Karasawa will rely on "Kesouyan" in the future.
After Tang Ze returned to "Kesouyan", he went directly to the "Physical Evidence Examination Section".
By the way, the "Physical Evidence Inspection Section" does not have a dedicated department, nor does it have a section chief, because it is more of a laboratory than a department.
Specializes in analyzing some of the physical evidence that needs to be tested in laboratory cases.
As for what they are specifically, there are too many, and there are all kinds of weird and weird things.
For example, this time, as Tangze explained before leaving last night, the items that needed to be tested were quite messy.
Analysis of the fibers, oils, and seemingly cosmetic substances that fell on the clothes, as well as the hair that Karasawa found last night, and the skin tissue attached to the nails of the deceased.
These are all evidences that Tangze discovered using his super-olfactory sense on the deceased and need to be analyzed.
Although I don't know if it is useful, at least these things appeared on the body of the deceased.
Karasawa didn't know if it would be useful, but he needed to figure out why these things appeared on the deceased.
"Everything that has passed must have traces." Tang Ze is restoring what the deceased did during his lifetime.
However, perhaps because there were too many items that Tang Ze asked to analyze yesterday, and because there were relatively few people and hands in the laboratory, Tang Ze still had to wait a little while to get the analysis results of all the physical evidence.
Of course, the two physical evidences that Tang Ze personally found yesterday have already been examined.
First of all, the hair found on the head of the deceased was found to be type A female hair according to the instrument. It was dyed with natural ingredients for about a month.
On top of that, this woman has serious self-reflection.
Don’t you think it’s incredible?
You can even know clearly that the other party has a self-made roll.
But in fact, under the analysis of the instrument, this is nothing at all. You can clearly see images that are invisible to the naked eye.
This is the power of science. If you understand it, you will actually find that these are very simple things with the help of instruments.
And these can better assist the search.
Take the female hair found in the deceased's hair, for example. Knowing so many characteristics, are you worried about not being able to identify the owner of the hair?
After just reading these analyses, Tang Zeyou checked the analysis results of the suspected prisoner's skin tissue between the fingernails of the deceased Yingxi.
After comparison, it was found that the owner of this skin tissue had blood type AB.
After sending these two edited text messages to Takagi, Karasawa patiently waited for the analysis results of other physical evidence.
Not long after, the composition of the fibrous tissue attached to the deceased's clothes was also analyzed.
According to the staff of the "Physical Inspection Section", this fiber is often used in blankets and carpets for cars and is a very common material.
In addition, the oil stains on the clothes were analyzed and determined to be automobile oil.
When he saw these two test results, Tang Ze was sure of one thing.
The body was most likely moved!
Although the spots on the corpse did not show this before, it does not prove anything.
If the prisoner immediately moved the body and dumped it at the crime scene after killing Toshio Takekawa, it would be normal for the body spots to remain unchanged.
After obtaining these analysis results, Karasawa immediately contacted Officer Megure and asked him to formally investigate the case.
That's right, because the cause of death of this body was too vague, the case was not characterized at all last night.
Although the investigation was initially conducted as a homicide, if the circumstances are still not found, the case may be closed as an accident or death due to illness.
Now, after analyzing the attachments on the deceased, it is possible that the body was moved, which provides the basis for filing a case.
But to be honest, for Tang Ze, this has no real progress.
Although he had already determined that it was a murder, he still hadn't found out what special means the prisoner used to suffocate Takegawa Toshio to death.
With the information, Karasawa went to the Metropolitan Police Department, where Karasawa, Takagi and others needed to summarize the investigation status this morning and inform the investigators in charge of the case.
Of course, there is no need to say more about Karasawa. Takagi followed I Naoki very quickly. After receiving Karasawa's text message, he quickly found out the owner of the hair with type A blood.
This hair belonged to the lover Takegawa Toshio met with on the day of his death, but at the time of death, the other party had a perfect alibi.
"The employee who had a conflict with Takegawa Toshio was named Shinsuke Dote. We did not find him."
Naoki Kamei explained: "The other party said he was going back to his hometown today and made an appointment for us to meet tomorrow."
"Well, continue the investigation."
After listening to everyone's reports, Officer Megure nodded and said immediately: "In addition, the specific cause of death of Takegawa Toshio must be investigated as soon as possible, otherwise it will be detrimental to us in the long run."
This is of course, after all, if the method of murder is not determined, over time the case will likely be treated as an accident again.
This is a very real issue. Even if there is evidence that the body has been moved, which may be a homicide, it is not irrefutable evidence after all.
If there is no progress for a long time, they will not continue to waste energy on this, and the superiors will not allow them to continue wasting manpower and material resources on a case that has no progress.
So we can only hurry up!
It is their top priority to make new progress as soon as possible, whether it is to find evidence of homicide or to find out the murder method to confirm the possibility of homicide.
After the meeting, everyone's information has been integrated.
Although Dote Shinsuke, who seems to have the biggest motive at the moment, has not yet investigated, the other party has promised to meet tomorrow.
Of course, this does not mean that everything will be fine this afternoon. Karasawa thought for a while and finally called Aso Minoru and asked him to go with him to the club where Takegawa Toshio worked.
Karasawa also had his own considerations in calling him Aso Minoru instead of Takagi or Kamei Naoki.
If Karasawa takes Takagi and others with him, it may cause Kujo Hiro to have unnecessary associations, fearing that committing suicide will endanger the company's interests and create a defensive mentality.
In this case, they will definitely put pressure on the lower levels to keep employees silent.
But if you take the forensic doctor Aso Minoru with you, it means that you just want to explore the possible reasons for Toshio Takegawa's accidental death, which will make it easier to achieve the purpose of questioning.
Of course, you still need to have some necessary language skills~
