528 Infinite Reincarnation Naruto Chapter 528 (2/2)

”But, Naruto, there is no extra trauma on the deceased's body. There are no traces of trauma on the neck or face. There is only a red spot on the forehead. What is the reason other than poisoning?”

Mumu's analysis is indeed correct. There are many ways to suffocate a person, including masking, strangling, drowning, poisoning, and even putting a plastic bag on the head.

But if there is no obvious trauma, there are only two kinds of drowning and poisoning. Masking and strangulation are not much to say. Even if it is a plastic bag, it will leave a thin strangle mark on the neck.

There is no water mark on the deceased's body, and there is a red spot on the back of the neck, no matter how you look at it, there is only one possibility of poisoning.

”This is also the most cunning aspect of the murderer. He used not only to leave no evidence, but also to make an alibi for him, because the murder weapon he used will automatically and spontaneously move Tsuji Village at some point. Kill.”

”Does the murderer install any timing killing device here?”

Mumu looked left and right, as if trying to find the'precise' timing killing device, making Naruto a black line.

”Mumu, you don't need to look at it. That thing is invisible to human eyes, it is completely colorless, tasteless and odorless.”

Hearing Naruto’s words, the chubby Uncle Mumu also gave up the idea of ​​finding that thing with his eyes. He looked at a guy who was not a few years younger than himself, but looked younger than his son, and said: ”Naruto People, don't sell it anymore, just talk about it.”

”Well, the murderer did not use a poisonous needle, let alone a rope or something, but carbon dioxide, to be precise, solid carbon dioxide, which is dry ice.”

”dry ice?!”

Kudo Shinichi and Hattori Heiji were stunned at the same time, and immediately looked at someone who was wiping sweat. Obviously, they already understood.

Naruto put his computer on the desk and said, ”According to my analysis, the murderer probably used the key to open the study door after Mrs. Tsujimura left, and then put some dry ice on the desk of the deceased. Dry ice will quickly sublime into carbon dioxide in the air, which can suffocate the dead without knowing it, and dry ice will also completely sublimate into carbon dioxide, leaving no evidence.”

”Dry ice...” Uncle Mumu pinched his chin, fully demonstrating his professionalism, and said: ”But will it go so smoothly? Although carbon dioxide can make people suffocate to death, the concentration of carbon dioxide is more than 10%. How much dry ice is necessary to put it in order to threaten people’s lives? And if the room is full of carbon dioxide, you should notice an abnormality when you come in.”

”This is very simple. Because the doors and windows were locked at the time of the incident, there was only a gap in the door under the door, so the air in this room is not convective. Because the carbon dioxide is dense, it will remain around the body of the deceased. . And I checked the case of the deceased. He had three highs at the same time, that is, high blood pressure, high blood lipids, and high blood sugar. Last year, he had a heart bypass operation. For a person with three highs and heart disease, 5% The concentration of carbon dioxide is deadly enough.”

Naruto paused, took a deep breath, and continued:

”The 5% carbon dioxide concentration is not fatal for the average person, and when the door is opened, the air convections, reducing the carbon dioxide concentration in the study, and carbon dioxide is a colorless, odorless and odorless gas. It's abnormal.”

”Then the murderer is...”

”First of all, if you can get the deceased or Mrs. Tsujimura, if you have another one. Second, you can find Mrs. Tsujimura’s plan. In summary, you can be sure that the murderer must be a character inside the villa, and for a long time. Staying in this villa, can do this, except for the deceased himself and Mrs. Tsujimura, there are only two people, Mr. Tsujimura Takazen and the housekeeper Mr. Koike. And Mr. Takazen went out early in the morning, and it was. We arrived a few minutes before we arrived here, and Sachiko had been with Mr. Guishan at the time, so Mr. Guishan had no time to commit the crime. The only thing left is you, Mr. Koike, the housekeeper!”

The case can be said to be a turnaround. After experiencing the impact of the father killing the son, and the wife killing the husband, this case finally saw a change in the evil servants killing the master.

Fumio Koike's forehead was in cold sweat, and he looked at Naruto in horror, and said: ”Sergeant Uzumaki, you are just kidding, why should I kill the master? I have no motive to kill at all!”

”No! You have! Your motive for killing is in my computer!”

Naruto opened his laptop, and it showed the information that Suzaku had uploaded to his computer not long ago. It was a man in his 20s and 30s. Koike Fumio suddenly changed his face when he saw the photos on the computer. .

”He... he is not...” Tsujimura attacked and looked at the person displayed on the computer in shock.

”Mrs. Tsujimura, do you know this person?”

”Well, yes, this man is my ex-husband Kenji Yamashiro’s younger brother, Kentaro Yamashiro. However, after Kenji Yamashiro was imprisoned, Kentaro also disappeared. I wanted to give Sachiko to him, but I couldn’t find it. he.”

”Yes, the man in the photo is Kentaro Yamashiro, the true identity of Mr. Fumio Koike!”

”what?!”

Everyone feels that their nerve toughness has been tested a lot today, and the changes have impacted their nerves. This change, except Naruto himself, is afraid that no one will think of it.

Naruto looked indifferently at Koike Fumio, who lowered his head, and said, ”In order to find out the truth about your brother's imprisonment, so you went for cosmetic surgery and became like this, and under the pseudonym Koike Fumio, came to Tsujimura’s house as a housekeeper. , And it took seventeen years to do it. I think when Mrs. Tsujimura heard the truth from Tsujimura 20 years ago, you should have heard it accidentally, so you chose to kill ~ kill. Hatred, kill Tsujimura, right? As for Mrs. Tsujimura, I think you think she betrayed your brother, so you have to punish her, right?”
