Chapter 56 Section 56

"...Therefore, there are no contradictions in Sawamura's testimony. The time of returning to the izakaya after the murder is also consistent with the testimony of those present. The route to 'Green Rock Village' was checked, and no unnatural places were found. Considering the time and the surrounding conditions at the time, this matter is completely reasonable for the fact that there were no witnesses. I The report is over." Nonogaki concluded the report pretentiously, and sat back in his seat. As usual, the police held a search meeting in the conference room of the Glass Police Station.Although the leading figures are still the same old faces, their expressions are obviously different from those a few days ago.The most notable ones are Director Tomita and Criminal Police Section Chief Okamoto and others.Perhaps, they were breathing a sigh of relief for the smooth resolution of the case and not having to suffer from the cowardice of those in the county police headquarters.

Compared with the people in the police station under their jurisdiction, the expressions on the faces of the people in the first search section of the county police headquarters seem to be a little more complicated.Although the case was successfully resolved, they must have felt a little regretful that the discovery of the abandoned body case was not a homicide, but just a negligent death. Having said that, it took less than a week from the discovery of the body to the resolution of the case.For everyone, this is a happy event.Therefore, the atmosphere of the entire meeting seemed quite soft.

Although the Kawahata couple's initial confession obviously contained many doubtful points, after referring to Sawamura's confession, all doubts can be said to be resolved.Right now, both Shigeharu Kawahata and Setsuko have admitted that what Sawamura said is true.Both of them lied in order not to trouble their daughter's friends before. Now that Sawamura has surrendered himself, there is no need for the couple to continue to hide the truth. In addition, the physical evidence that proved what the couple said was true began to appear one by one.The police investigated the light truck at Sawamura's home and found a few hairs on the shelf.Although DNA identification is still being carried out, judging from the shape and nature of the hair, those hairs should belong to Masaji Tsukahara.

Later, the police found some sleeping pills identical to those that Shigeji had given to Tsukahara from the drawers in the living room of Kawahata's house.Judging from their composition, they are exactly the same as the sleeping pills detected in Tsukahara's blood.At the same time, according to the doctor who prescribed this medicine to Shigeji, Kawabata Shigeharu had suffered from mild sleep disturbance five years ago, and those medicines were prescribed by the doctor at that time. Even so, there are still unresolved doubts.That's why the accident happened. The person in charge of the identification department stood up and began to explain the situation.According to the person in charge, the appraisers have started a reproduction test in "Green Rock Village" since this morning.

"...In other words, although there is no obvious abnormality in the underground boiler, if the air intake is blocked for some reason, the boiler will show incomplete combustion. Although the suspect's memory is vague, it is impossible to determine The cause of the blocked air intake, but we suspect that maybe the cause is the cardboard boxes around the air intake. It may be that the cardboard boxes folded flat against the wall fell down and blocked the air intake. No After the complete combustion phenomenon occurs, the key to the problem lies in the concentration of carbon monoxide in the 'Kaiyuanma'. In yesterday's test, the maximum concentration was 100ppm, and the average concentration was about 50~60ppm. In addition, the boiler has combustion State monitoring skills, after the incomplete combustion state lasts for more than half an hour, the boiler will automatically stop. The test results under this condition are not consistent with the concentration of carboxyhemoglobin in the body."

"What's going on here? In that case, the situation isn't right?" Hoji, the head of the first search section, frowned dissatisfiedly. "As I said before, there may be other factors." "What other influences?" "For example, the weather of the day. If there is a strong wind that day, causing the gas in the chimney to reverse flow, the concentration of carbon monoxide will rise sharply. Indoors, the concentration may even rise to 1000ppm." "So that's how it is." Although he didn't know how much Hoji understood, he still nodded, "That is to say, it's actually like this: Although the fundamental reason lies in the suspect's personal fault, the cause of the death accident It appears, but is it the result of multiple accidents?"

"Exactly. Then we plan to continue the experiment." "Understood. Please continue." Suiji slightly raised his hand.Judging from his expression, his mood seemed to have improved again. It seems that the whole case is coming to an end.Nishiguchi, who was watching from the sidelines, thought to himself.Since the conditions that caused the accident were so difficult that the appraisers could not reproduce it, the possibility that Shigeharu Kawabata deliberately caused the accident is extremely small.Negligence of duty and abandonment of the corpse, it seems that the case is basically settled.

However, Nishiguchi always felt that he was in a panic.The reason was the conversation between him and Yu Chuan yesterday.The physicist once said that it is impossible to reproduce the experiment successfully.That being the case, will Yukawa know any way to reproduce it? Wonsan stood up and began to give a report.What he narrated was roughly the latest situation about Xianbo handsome from the Metropolitan Police Department.Hozumi started talking and laughing with Isobe beside him.The rest of the people also began to whisper.Not only them, it seems that all the investigators have lost interest in Xianbo.

After the case is resolved, after a while—— Or go to comfort Chengshi.Xikou thought to himself.Sometimes, the identity of the police can play a big role.During the trial, I can always be by her side. Thinking of this, Nishiguchi finally relaxed a little.
