When they first met, Tsukidate was the one who urged him to hurry up and pack his luggage. He was a slow and dull researcher.
His height is around 180cm, which is consistent with the prisoner's witness information.
Of course, this alone doesn't mean anything. After all, although Neon is generally short, there are some who are 180cm tall.
But height is nothing.
But in addition, fungal spores were also found on the prisoner's hair.
You should know that in addition to bacteria, Tsukidate Junko also said that their laboratory also often uses shiitake mushrooms.
It is also normal for my grandson to come into contact with shiitake mushrooms in the research institute.
In addition, the prisoner is proficient in chemicals and can even prepare a killer weapon such as silver cyanide, so he also meets the conditions.
It is difficult for most people to know this chemical knowledge. Even if it is available online, the silver cyanide channel is not available to ordinary people.
And the institute happens to be the place where you can get it.
In addition, the other party had been abroad before, and the suitcase was sent back from England.
Later, Tangze retrieved Wu Sunli's information through the police system and found that he went to study and study two years ago!
The time is right again!
Two years ago, the serial murderer who killed three young girls suddenly stopped committing crimes.
At that time, the police speculated that the other party might have sensed the danger and chose to lie dormant.
In this case, fleeing abroad is undoubtedly a good way to evade search.
But the only thing he miscalculated was that even though the criminal responsible for the case had retired, he still clung to him, which triggered a series of subsequent cases.
Coupled with the death of epidermal tissue bacteria in the petri dish, every piece of information pointed the suspicion at Wusun Li.
If these clues were placed on one person alone, it would really be nothing. Two or three of them could be considered coincidences.
But if all the conditions are met, then the coincidence is no longer a coincidence, but the real number one suspect.
So when Karasawa stated his reasoning, Ayanokouji Fumimaro immediately said: "From your analysis, Isun Li is indeed the biggest suspect at present.
It is also hard for me to imagine that a researcher with a rigorous personality would let the bacteria cultivated in two petri dishes die at the same time."
"So, we got a blessing in disguise?" Qingtian Yuhua's eyes were a little dazed, and she had not yet reacted to the rapid change in the situation.
At the beginning, all the bacteria in the petri dish were dead, which meant that all the clues were lost, which was naturally considered bad news.
But unexpectedly, in an unexpected turn, Tangze Criminal used this bad news to guess that the prisoner was in the research room, and finally locked the suspect.
Although no arrests have been made yet and everything has yet to be verified, out of trust in Tang Ze, they have already believed in Tang Ze's judgment.
Under normal circumstances, since these are all indirect evidence, and when taken together they only reveal the other party's suspicion, a search warrant cannot be applied for.
After all, when a search warrant requires conclusive evidence, this kind of clue that is all speculation and has no obvious direction is obviously not recognized.
But these rules obviously do not apply in this case.
Because the impact of these serial murders is too bad.
Two years ago and now, a total of six people have died, and the Kyoto police force has been under great pressure.
Now that I heard that Karasawa had found the suspect, the superiors did not take into account the normal rules and directly issued a search warrant and asked Ayanokouji Fumimaro to lead the search.
Braving the darkness, the group soon arrived at Wusunli's home. The light from the windows revealed the news that the owner of the mansion was at home.
Seeing this, the group felt a little calmer, and then followed the plan before setting off to surround Wusunli's mansion.
Although the other party's house was slightly remote in Kyoto, it was a single-family house. Karasawa followed Ayanokouji Fumimaro and even had to go up a small flight of stairs before arriving at the other party's door.
Because the siege net had already been set up, and it was not yet certain that the other party was the murderer, Ayanokouji Fumimaro stood in front of the door and did not break the door violently, but knocked politely.
However, after knocking on the door, the room was still quiet.
But the lights were clearly on in the house, but no one responded and there was no movement.
This strange state made everyone unconsciously increase their vigilance. After Ayanokouji Fumimaro knocked on the door to no avail, he winked at Karasawa and told him to retreat, intending to violently break the door open.
"Need not."
Karasawa shook his head in a low voice, and immediately took out the [Universal Lock Picking Tool], and easily opened the door of the other party's house under Ayanokouji Fumimaro's surprised gaze.
"I'll go first!"
After the door opened, Ayanokouji Fumimaro took out his pistol and pushed the door open first, while Karasawa did not argue with him.
Although he doesn't have a gun in his hand, he doesn't need protection due to his skills. But this is Kyoto after all, so he will naturally not refuse the other party's kindness.
Ayanokouji Fumimaro entered the room cautiously, and after exploring the living room, waved to Karasawa and others.
A group of criminals entered one after another and began to perform their duties to check the bedroom, but then they all shook their heads to indicate that there was no manpower in the room.
"It's empty." Ayanokouji Fumimaro said with an ugly face: "Did this guy run away?"
"You can't make such an arbitrary decision now."
Tangze said: "Anyway, let's search the room first. If we can find air in the room, we can issue an arrest warrant directly."
Hearing Karasawa's words, Ayanokouji Fumimaro nodded repeatedly and ordered a search of the entire room.
"Police department, we have found Wu Sunli!"
Just when both of them thought they would get nothing, suddenly a middle-aged criminal ran over with a serious look on his face, "He's dead!"
"What!?"
Hearing what the other party said, Karasawa and the two were shocked. Ayanokouji Fumimaro quickly said: "Take us there quickly!"
After following the middle-aged criminal out of the mansion, the two followed each other along the fence to the back of the mansion.
Here, there is a dilapidated small door.
But this gate is different from the mansion in that it is close to the ground, and behind the gate is a space that spreads downward.
In other words, Wusunli's mansion is a two-story building, but the first floor is dug downward, and the second floor is for living.
After the group entered the room, they quickly saw the scene inside.
Unlike the rich decoration upstairs, the decoration downstairs seems very simple, even a little shabby.
However, basic facilities such as sofas and tables are still available.
Under dim lights, everyone arrived at the living room, and then discovered that the walls were covered with news reports about the "Girl Serial Murder Case."
Of course, all the murder reports that happened in the past few days are also included.
It is obviously a very consistent psychological profile of a "happy souvenir offender".
As for my hands that they wanted to grab, they just fell down in front of the table.
Tang Ze stepped forward to check and made sure that the other party was silent: "Inform the people from the scientific search and research team to come over. There is a lot of evidence here that needs to be investigated."
Ayanokouji Fumimaro nodded, then explained immediately, approached the body and asked, "Did he die from taking poison?"
"There is a bit of garlic smell coming from the mouth. It is likely that he died of poisoning caused by methionine." Tang Ze stood up and looked at the table and found a pot of barley tea placed on it.
And at the feet of the corpse, there was a broken cup.
"Did you commit suicide?"
Ayanokouji Fumimaro put away his pistol, saw the same two things, and judged: "I am afraid that after destroying the bacteria in the petri dish, he felt more and more that what he did at that time was drinking poison to quench his thirst.
Then I realized I couldn't escape, so I chose to commit suicide at home by taking poison."
“The room still smells like burned paper.”
Tangze's nose moved slightly, and he followed the smell in the air to an iron bucket in the corner. "It seems to be something like paper that was burned. Come and collect evidence personally."
Tang Ze did not touch these burned papers, but called professional personnel to come over and extract them.
Even though they are burnt black, these papers still maintain relative integrity. If they are handed over to scientific research, they may be able to find some clues.
Although Wu Sunli is already dead, in order to close the case, it is best to restore the entire case to its original state as much as possible.
After a young researcher ran over, Tangze stood up and looked around, seeing a black backpack placed on the coffee table next to him.
Karasawa put on his gloves, opened his backpack, and took out the items inside.
They were daggers wrapped in evidence bags, and the blood stains on them were not even wiped off, but just dried on them.
"The murder weapon has been found."
Karasawa's words caused Ayanokouji Fumimaro and other criminals to gather around them. Looking at the blood-stained daggers, everyone showed a look of disgust.
"I asked why I just saw a lot of weapon racks in the dance inside, but no weapons." One of the criminals said with a look of disgust: "It turns out they were placed here."
"It's really perverted fun."
Ayanokouji Fumimaro also showed the same expression: "But in this way, we can be sure that we have found the real murderer.
This serial murder case has finally come to an end."
After hearing Ayanokouji Fumimaro's words, all the criminals present showed relief, as if a heavy burden had been lifted off them.
In fact, this is indeed the case. The serial murderer from two years ago suddenly appeared and killed three people again, which suddenly put the police under tremendous pressure.
Even though Wu Sunli has died from poisoning now, the evidence has not been destroyed yet, which is enough to convict him and close the case.
However, Tang Ze still had some doubts in his heart when he looked at the dagger in his backpack.
Since he was already about to commit suicide by taking poison, why did he still need to put away these murder weapons?
This incongruity was like a tiny fishbone stuck in Tangze's throat, making him always aware of it.
However, Tangze didn't bring it up immediately. After all, everyone was celebrating the capture of the criminal, and he wasn't so ignorant as to embarrass the scene.
Of course, he would not hide his thoughts. When it was time to close the team, he went to Ayanokouji Fumimaro and explained this point.
"Are you suspecting that my Sun Li's death might not have been a suicide?"
After Ayanokouji Fumimaro heard Karasawa's words, his brows furrowed as if he could pinch the words.
"If it was suicide, why did you need to take away the murder weapons and put them in the backpack?"
Tang Ze said: "These are his collections, his precious treasures.
You and I both know how risky it is for criminals to hide a murder weapon at home. Once it is discovered, it will be irrefutable evidence.
But he still kept these murder weapons in a good collection and even bought a display stand.
In this case, it can be seen that he values these "souvenirs" in his heart.
In this case, there was only one possibility for him to wrap the murder weapon and put it in his bag.
That means sensing danger and preparing to escape.
"But this refutes his behavior of committing suicide by taking poison."
He unconsciously stroked the chipmunk's head with his fingers and said solemnly: "So you suspect that someone killed my Sunli?"
"Yes." Tang Ze nodded and said, "I do have this idea, but this is also a judgment based on on-site intelligence."
"I'll keep an eye out."
Ayanokouji Fumimaro said: "But the opinion above is definitely to end this case as soon as possible.
So I’m afraid we can only investigate later and find supporting information before we can speak out.”
"It doesn't matter. I am the murderer of six people. This is a fact."
Tang Ze nodded and said: "This case can be closed, but what we want to investigate is who killed Wusun Li."
"I always feel like there's a conspiracy behind it." Ayanokouji Fumimaro frowned unconsciously.
"Let's wait for the results of the investigation from Kesouyan." Tangze said, "Perhaps there will be some progress by then."
In the end, the two reached an agreement to continue the investigation, but not to affect the conclusion of the serial murder case.
After closing the team, the criminals from the Search Section 1 started a celebration party to reward them for finally solving this big case.
But Kesouyan is in mourning.
Because prisoners committed suicide, they had too many areas that needed to be tested and identified.
The corpse must be autopsyed, and each knife must be used to find the corresponding deceased based on the blood stains and shape on it.
Even the ashes of burned paper that Karasawa found from the bucket had to be identified.
It can be said that the workload is very huge.
The next morning, Tangze visited the members of Kesouyan with a rewarding breakfast.
Although they are not subordinates of Tokyo, they are in the same organization and have the same working conditions, so Karasawa also appreciates their hard work.
After the intense work of this group of young people, the results of the inspection of my grandson's house and the evidence in the house were finally cleared.
First, silver cyanide was found in Gosunri's room, and it was consistent with the ingredients in the package sent to Ryōichi Tamaki.
It is certain that the one who wants to kill Tamaki Ryōichi is Gosatsu Riki.
In addition, the blood stains on the five murder weapons also corresponded to six victims, and the fingerprints on them also confirmed that only Wusunli was the one.
And the hair attached to Sarutobi Yuji's clothes can also be confirmed to be Gosatsu's.
These two items can be said to be key evidence that confirms that Wu Sunli is the murderer of the serial murder case.
In other words, even if Tang Ze was worried about Wu Sunli's death, there was still someone behind it.
But at least I can be sure that it will not be the person who planned it and put the blame on my grandson Li.
