Not long after the call was made, Naoki Kamei hurried over.
"Senior, I'm sorry!"
As soon as they met, Naoki Kamei bowed ninety degrees to Karasawa and apologized: "I really caused you trouble!"
After all, he is a member of the scientific search and research team. Even if the people below him are punished, Tangze, as the leader, will inevitably have an impact.
If it weren't for his reputation and the fact that he recently went to Osaka for exchanges and was not in Tokyo, he, the leader, would have to bear a certain amount of responsibility for the matter involving Hisashi Kamei.
"Okay, okay, get up quickly."
Karasawa helped Naoki Kamei up and said, "What's the trouble? The matter hasn't been settled yet."
"The investigation results have come out, senior, please stop comforting me."
Hearing this, Naoki Ueijing shook his head: "It turns out that that guy Kuji is causing trouble for you, senior.
I told him that he was suitable for university teaching or research, and he insisted on joining the criminal department like me.
But it's not a bad thing now. With this blow, he can go back to doing what he is good at.
His university teacher asked me to persuade him to go back."
"Senior, when you say this, why do you feel like a bad thing has turned into a good thing?"
Koshizui Nanatsuki looked dumbfounded when he heard this: "He made a mistake and was expelled. How come the seniors and his teachers are even happier?"
"You said there are two missing, and there are my parents." Naoki Kamei sneered and said with a last strike.
Should I say they are really brothers? They can do it so easily.
"Okay, okay, just say less teasing words."
Tangze said: "Naoki, you too, don't look like you don't care. After all, this is a blow to your brother's head, and it might be a big blow."
"I know, so I plan to go to where he lives to see him later." Hearing this, Naoki Uyei also suppressed the smile on his face, with a hint of worry in his eyes.
Obviously, although he always hurts his younger brother, he still cares about him.
This mistake was so serious that even the media made a fuss about it, and it must have dealt a big blow to Hisashi Uyei himself.
In this case, you still have to worry about the other party's mental state. If you can't stand the blow and become depressed or even commit suicide, you will be in trouble.
So Naoki Kamei planned to pay a visit to see how his brother was doing.
"Then I'll go with you," Tang Ze said.
"Senior" Naoki Kamei hesitated when he heard this: "It's not necessary, the matter has been settled."
"You also said before that your brother is engaged in scientific research and is very good."
Tang Ze said: "I know this kind of person, and he must be very cautious in experiments.
So I want to investigate again and confirm the truth for myself."
"I understand." Uekai Naoki was somewhat moved when he heard this: "Thank you, senior!"
In his opinion, Tangze continued to investigate this thankless matter just because of his face.
"Then without further ado, let's set off now!"
At the urging of Nanatsuki Koshimizu, the three of them drove quickly to the apartment where Hisashi Kamei lived.
After arriving at the place, the three of them identified themselves to the apartment manager and went directly to the door of Hisashi Uyei's house.
But after knocking on the door, no one responded.
At this time, Naoki Kamei became anxious and quickly called the apartment manager to get the spare key and entered the other party's home.
"Kuji!"
All the way to the bedroom, he found the other party lying on the floor next to the tatami. Naoki Kamei rushed forward in a hurry.
After all, this scene looked like Hisashi Kamui committed suicide because he couldn't think about it. Coupled with what happened before, Naoki Kamei subconsciously started thinking in a bad direction.
But Naoki Kamei just tested his breath and pulse, and then breathed out: "I'm still breathing, I probably just fell asleep."
Having said this, Naoki Uei relaxed his shoulders, sat on the floor and kicked his younger brother: "Kuji, get up!"
Being shaken by such a shout, Hisashi Uei slowly woke up and looked at Naoki Uei with a confused look on his face: "Brother? Why are you at my house?"
"After hearing about that incident, I was a little worried about you."
Uye Naoki said: "It just so happens that senior also wants to investigate the case personally, so I came to see you.
Who would have thought that you had not responded after knocking on the door just now, so I thought something had happened.
So I quickly called the apartment manager and asked him to help open the door with the spare key."
Speaking of this, Naoki Kamei seemed to have remembered something, and hurriedly came to the door and thanked the young man standing at the door: "Mr. Administrator, thank you, it's okay."
"As long as it's okay, I'll go down first." The young administrator in his thirties smiled and waved his hand before bidding farewell to Uye Naoki.
"Kuji, come to your senses."
Seeing his brother still sitting there in a daze, Naoki Kamei kicked him: "Hurry up and make tea for the guests!"
"No, no, no." Seeing that the other person was still in a daze, Tang Ze smiled and waved his hand, "He just woke up, let him take it easy."
"I'm awake, I'm going to make tea!"
After hearing his brother's words, Hisashi Kamei reacted and quickly got up to pour tea for several people.
Several people also came to the sofa in the living room and sat down under the invitation of Naoki Kamei.
"This is the situation. Senior hopes to investigate on his own."
After sitting down, Naoki Kamei told his brother about the situation, hoping that he would cooperate.
"I see."
Hisashi Kamei showed a grateful smile towards Karasawa and the two, and then said helplessly: "But to be honest, when I got the news, I couldn't believe it myself.
To be honest, I have done a lot of research with my tutor. I am very rigorous in experiments no matter how big or small. My teacher has praised me for this many times.
When collecting evidence, I certainly did not handle the forensic tools casually.
Although there is no danger, I can't be more careful when it comes to human life.
Even if it’s a box for storing props, I always put it on a string with my house keys and never leave them.”
Speaking of this, Hisashi Kamei said dejectedly: "Rigorousness is the foundation of being a scientific worker, and I have always maintained this rigor.
But now that something like this has happened, to be honest, I have lost some confidence."
At this moment, the doorbell of the room rang again. Hisashi Kamei stood up and went to the door to look at the surveillance camera nearby. He found that the people coming were Shoji Okawara and Yamazaki Kawatani, the section chief of their forensics department.
"I've already written my resignation letter. I'm causing trouble to you two!"
After opening the door and inviting the two of them into the room, Hisashi Kamei took out his resignation letter that he had already written and pushed it in front of them.
"I'll accept the resignation letter for now."
Yamazaki Kawatani looked at Hisashi Kamei and comforted him: "Don't be too aggressive. I will also help ask the superiors to see if they can let you stay again."
"Forget it, I really feel ashamed to accept the kindness of the section chief."
Hisashi Kamei bowed his head in shame and said, "And Master Okawara, who taught me the knowledge of forensics, I'm sorry for discrediting you."
"You seem to have a cold."
Yamazaki Kawatani heard what Hisashi Kamei said, but did not answer his words. Instead, he noticed that his nasal voice was a bit thick, "Did you take protective measures when you were at the scene?"
"Well, I was wearing a mask properly at that time." Hisashi Uyei nodded.
"Where are your hands? Have you washed them properly?" Okawara Shoji then asked again.
"I'm sorry, I forgot."
Kushi Kamei's mind was in a mess and he had no confidence at all: "To be honest, I couldn't figure it out myself. I was a little dizzy because of the fever at the time, so I thought I wouldn't mess it up."
"Just tell me if you are sick." Okawara Shoji sighed: "You can't just hold on."
"Excuse me, when did you realize that you made a mistake?" Tang Ze looked at the two people and asked.
"The day after the identification results of the third case came out."
Yamazaki Kawatani heard the question from Karasawa, his immediate boss, and quickly replied: "The subordinate in charge of testing called me and asked me if the cotton swab was contaminated.
Because they found that the degree of blood infiltration seemed a little unnatural.
Then I suddenly realized that there might be something wrong when we were collecting evidence, so I asked them to investigate in private.
Finally, several on-site evidence collection personnel were investigated and the DNA of Hisashi Uyei was discovered.”
"So that's it."
Tangze nodded and then continued to ask: "I heard that cigarette butts of the same brand were found at the crime scene?"
"In this regard, although it is said to be a crime scene, it is not next to the body."
Okawara Shoji heard this and explained: "Those cigarette butts were just found nearby, and that brand is also the most common brand. It may be a coincidence."
"But it seems to me that there are no fingerprints or saliva left on all the cigarette butts?" Koshimizu Nanatsuki couldn't help but asked: "In this case, could it be a coincidence?"
"This season, there are quite a lot of people wearing gloves. If you add a filter, it can completely cause this situation."
Okawara Shoji sighed and said: "But now, there is no way to judge whether it is the message left by the murderer."
Indeed, given the current logistics problems in the Forensics Department, there is a question mark as to whether the physical evidence collected can continue to be used as evidence.
So don't expect to find new clues from the originally collected evidence. Opponents only need to say that these are questionable evidence collected by erroneous forensic investigators, which is enough to overturn the validity of these evidences.
Therefore, it is not an exaggeration to say that the previous evidence has been wiped out. Unless there is a turning point that can overturn everything before, don't even think about it.
The two people from the forensics department quickly left, while Karasawa and Koshimizu Nanatsuki stayed for a chat and left soon after. Naoki Kamei stayed, intending to spend some time with his brother and enlighten him.
.
After returning to the science search and research department, what was in front of the two of them was a silver tool box. This was the box that Hisashi Kamei must bring with him when he went out to the crime scene. It contained tools for collecting evidence.
"Jiusi said that it is locked when not in use."
Nanatsuki Koshizui wore gloves and opened the tool box as he spoke, revealing the tools inside.
Test tubes, rubber gloves, various types of evidence bags, chemical reagents
The boxes are densely packed with various props neatly arranged, and you can see the seriousness of Hisashi Uyei.
"This is the DNA swab that caused problems in this case." Koshimizu Nanatsuki took out one of the cotton swabs in a long bag and looked at it.
These cotton swabs come in single packs, and the swab sticks are very long.
After Tang Ze took out all the cotton swabs, he found a touch of green in the bottom corner of the box.
This is something that shouldn't be in the tool box because it looks like the leaves of some kind of plant.
"Are these cypress leaves?"
Seeing Karasawa's actions, Koshimizu Nanatsuki also came up and observed carefully: "Did the leaves from which crime scene fall into the box?"
"It's not clear yet." Tang Ze shook his head and said, "Let's keep it for now."
"Understood." Koshimizu Nanatsuki nodded, took out the evidence bag and put it in it.
The two of them went to the Forensic Science Department and asked Uekiji's colleagues.
"I really can't believe that Kuji would make such a mistake."
A new forensic examiner who entered the same batch was a little reserved when his immediate boss came to ask questions, but he still frankly expressed his thoughts: "To be honest, he is very stereotypical of a Virgo, pursuing perfection in everything he does, and he has a bit of obsessive-compulsive disorder.
I feel that it is precisely because of this that he was able to take first place."
"I remember you were in the same class as him, right?"
Tang Ze looked at the female forensic examiner in front of him and asked: "Then let me ask, are any of the recent crime scenes located under a cypress tree?"
"Is it a cypress tree?" The female forensic examiner recalled it carefully and then said: "There should be none."
"I understand." Tangze nodded to express his gratitude.
"Senior, where should we go next?" Koshimizu Nanatsuki asked after following Karasawa out of the room.
Tangze: "Go to the crime scene again."
Apartment in Cupido Town, Nerima Ward.
This is also the scene of the first crime this time.
"Is this bathroom the scene of the first crime?" Tang Ze said.
"Well, according to the file, the deceased was a woman living alone. Although the idea of suicide prevailed at first, there was no suicide note and no clear motive for suicide, so to be on the safe side, we called in the Science Research Institute to investigate."
Koshimizu Nanatsuki said: "When the body was found, there were glasses and empty beer cans in the living room.
After collecting DNA from the mouth of empty beer cans, DNA other than Itanium was found.”
"So the possibility of a murder case becomes stronger." Tang Ze nodded.
"I remember, the cigarette butts are downstairs." Tangze said as he came to the balcony and looked at the green belt below.
The cigarette butt is under a big tree.
"To be honest, it's really difficult to judge whether this location is related to the case."
Koshizui Nanatsuki sighed: "All I can think of is that after the murderer committed the crime, he flicked the cigarette butt from the balcony to the root of the tree downstairs."
"But I did make a new discovery."
Tang Ze looked at the green belt aside, with a smile on his lips: "Look at the trees further away."
