Torii asked his own question: "If they are good friends, why do they turn against each other?"

Lin Lei turned his head to look at Lu Yun and Qiao Yan, and asked, "At the beginning, you asked me why I investigated Takekoichiro's overseas travel records, do you know the answer now?"

Lu Yun and Qiao Yan both nodded, but did not speak.

This aspect of the situation made women talk about some "that", so Lin Lei no longer talked to them, but said to torii: "Between comrades, it is easy to spread a disease, you should know what it is, right?"

Torii gasped and replied in a trembling voice, "Could it be ......"

Lin Lei frowned and explained, "All this is my conjecture. So, I need to verify. Unfortunately, the result of the verification is that Ichiro Takekoichiro did secretly go abroad for medical treatment more than once, and the country he went to was Thailand. Thailand's medical level is much behind that of Yuben, and he is willing to seek the near and far, so what kind of disease he has is about to come out. ”

After being silent for a moment, Torii said: "As far as I know, because of the flood of REN demons in Thailand, the level of local AIDS treatment is relatively high in Asia.

In other words, Chuchu Chukachiro's AIDS should have been transmitted to him by Katsu Kojima - after getting a terminal illness, Chuchichu Chuichiro killed him in order to take revenge on Katsu Kojima.

Because he himself was terminally ill and his death was not far away, Ichiro Chuchiko finally committed suicide to cover up the truth of the case.

Unexpectedly, the ultimate truth of the case is that two good friends turned against each other......

The mystery of everything has been revealed.

Lin Lei finally gave Torii another look at the context of the case.

The first flaw in the case was that Ichiro Chucho fell from the roof, which was the beginning of Lin Lei's suspicion of him.

Perhaps Ichiro Chuchichu wanted to show that he was "extremely shocked" after seeing Katsu Kojima's death at that time, so he added such a "performance" to the table.

Of course, this suspicion is only suspicious, and it does not represent anything, nor does it prove anything.

The second key point is those "perverted videos" in Kojima's computer.

There are no normal OOXX videos, all of them are perverted videos, which shows that Katsu Kojima is not a normal person, and there is a high possibility of "perverted".

The third key point, which directly reveals the clues that Kojima and Takenaka may be "friends", is the investigation of the time when the two are on duty.

The two of them were on the night shift for a significantly longer period than normal, so it was very likely that the two would be "together" at night.

The most critical place is actually the most difficult mystery to explain at the scene of the crime.

All reasoning must be based on the interpretation of the crime scene.

The murderer in this case came and went without a trace, and if this problem is not solved, all reasoning will be in vain.

As with all "closed room murders", the first thing to rule out is the possibility of the deceased committing suicide!

Chuchiko Koichiro is a police officer, and he knows this very well.

There are a lot of suspicions about him, but the Hokkaido police have not tracked them down for the time being.

Once the "master" comes, his little trick of killing people is easily exposed.

AIDS is a terminal illness, and his days are numbered.

If he commits suicide, then under normal circumstances, no one will suspect that he is the murderer of the first case - this case, no matter how you look at it, is a serial murder case.

As he wished, the Hokkaido police were misled by him.

The Hokkaido police described the real culprit as "a judge from hell", and they have tacitly assumed that another murderer killed the police.

Lin Lei took out a medical record from his pocket and handed it to the torii police officer: "This is the medical record of Takekoichiro's treatment of AIDS in Thailand, and it can be regarded as a very important link in the chain of evidence." ”

There is no "murder weapon" in this case, DNA comparison and other ironclad evidence, so every link in the evidence chain is very critical and can help people restore the truth of the case.

Torii Detective took Takenakachiro's medical records, nodded and said, "The level of AIDS treatment in this book is higher than that in Thailand, but Takenakachiro is afraid of exposing his illness, so he went to a private hospital in Thailand for treatment, which is also a helpless move." ”

As Torii said, Ichiro Chugokuchi cannot be treated in his home country, and the reason is very simple and does not need to be repeated.

Lin Lei thought for a moment and said to Torii: "There is very little evidence in this case, after all, it is an old backlog - if I had been at the scene of the first crime back then, I believe I could have found ironclad evidence." Now, there's really no way - even the bodies of the dead have been cremated......"

There are usually two ways to close a case, one is perfect and ironclad, and the other is not much evidence, but after reasoning, it can connect the facts of the case, and there is supporting evidence to prove it, and if there is exclusive evidence, then the case can also be closed.

There was no trace of anyone entering or leaving the scene of Katsu Kojima and Koichiro Take's deaths, which is evidence of exclusivity......

There will be some follow-up investigations, such as how Katsu Kojima contracted AIDS and who the "upper family" made him sick, which will be left to the Hokkaido police to continue the investigation......

Everyone at the scene was silent, and everyone was in a bad mood.

Although the case was solved, no one felt joy.

At this moment, Torii Detective suddenly remembered something and asked Lin Lei, "Detective Lin, is Kagawa Mingcheng related to the case?"

Lin Lei's eyes deepened, and he didn't answer Torii's question for a long time.

Kagawa Mingcheng in the distance looked at his nose and nose at this time, bowed his head and said nothing.

After a long time, Lin Lei sighed and said to the torii guard: "There is no way to prove it. ”

Lin Lei didn't say "related", nor did he say "unrelated", but said "unprovable", which surprised Torii.

Lin Lei explained in a low voice: "I had a suspicion that Kagawa Akinari may have instigated or tricked Abe into killing the other two policemen, and then Abe committed suicide...... However, without evidence, it is impossible to find evidence. Abe is already dead, and what is reflected at the scene is either an 'accident' or a 'suicide after murder', both of which are possible, but there is no proof of death. ”

After a pause, Lin Lei continued: "Reasoning is very simple, but it is difficult to find evidence, or find a chain of evidence to prove the guilt of the suspect. ”

At this time, Lu Yun walked up to Lin Lei and said in a low voice: "Is there really no way to solve the last case?"

Lin Lei shook his head and replied: "Kagawa Mingcheng definitely did not appear at the scene of the crime, this is said that the police have investigated it countless times, unless the dead Abe comes back to testify against him......"

After a pause, Lin Lei continued: "This is just speculation. The most likely death of the last three was an accident - I'll try again, and you don't talk. ”

The place where Lin Lei and the others stood was far away from Kagawa Mingcheng, and Kagawa Mingcheng definitely couldn't hear Lin Lei's conversation.

Lin Lei walked quickly to Kagawa Mingcheng and stared at him for a long time.

Kagawa Mingcheng still lowered his head and remained silent.

Suddenly, Lin Lei said coldly: "Kagawa Mingcheng, do you know that Abe has always had the habit of writing a diary. Every day, he will write it down personally!"

Kagawa Akinari was stunned, raised his head, and blurted out: "Abe has a habit of writing a diary?"

Lin Lei stared at him coldly: "Yes." ”

Kagawa Akinari shook his head lightly and said, "Maybe, it had been several years since Abe left the welfare home, was it because of the pressure of work that he started keeping a diary?"

"Do you know what he wrote about yours in his diary?" Lin Lei continued to "cheat".

Kagawa Akinari smiled, looked up at the sky, and seemed to recall a memory: "When I was in the welfare center, I was very strict with them, I guess he would write 'a stern old man', right? I remember one time, Abe secretly played with matches, which ignited the quilt he was sleeping on, and I punished him for standing in the corridor for a whole night ...... that day."

Next, Kagawa Akinari babbled a lot about the past of the welfare center and Abe.

Lin Lei had been observing Kagawa Mingcheng's expression, and finally had his own judgment.

Kagawa Akinari should have nothing to do with Abe's death, otherwise the "acting" would be too high.

With this judgment, Lin Lei knew very well in his heart that the case could finally be closed......
