Chapter 7 Chapter Seven: The Corpse Under the Lighthouse

Nishi Shinjuku 8-chome is a wonderful place.Among the super high-rise buildings, small houses like matchboxes are divided into two parts by Ome Street.Some of these small dwellings are made of concrete, and some are entirely of wood. There are also small restaurants in between. They are crowded together in a chaotic manner, like a canyon between high mountains. But the wind on this street is very strong, and the open space that seems to be encroached is constantly increasing.Real estate developers continue to buy and sell houses, and land prices continue to rise. There is no building on the land bought by someone, but it is surrounded by barbed wire and a billboard is inserted.They are like the hands of the devil, eroding this land.

Here, in a corner of the open space that has been eaten away in this way, some holes were dug for no known purpose.On weekdays, children got into the barbed wire to play in the open space, so the owner of the nearest land put a rope on the edge of the cave and wrote a warning sign of "No Entry".But because the grass here is so lush, no one can see that there are caves in it. On the afternoon of June 21, a few particularly aggressive children living nearby got into this open space again.For children, the more forbidden places are, the more interesting they are, and the more they dare to enter the places that adults are not allowed to go, the more they can show their "heroic" spirit.

The leading child named A Jian said that this time he would go into the cave to have a look.So the group of children yelled: "too terrifying!" This guy named Ah Jian suddenly became energetic: "What's so scary about this! Let me prove it to you!" After speaking, he led these children into the grass and found the entrance of the cave.Looking down from the top of the cave, it was dark inside and nothing could be seen.And because the entrance of the cave is covered with weeds, it is impossible to see the bottom of the cave without leaning out from the edge of the cave.

There is no way, Ah Jian had to go down to prove his bravery.When everyone had reached the entrance of the cave, one of the children shouted: "Why does it smell bad!" "Yeah, it stinks! It's the smell of something rotten." "Someone must have thrown the dead cat and dog into it!" Everyone was yelling like this, and some timid children were so frightened that they cried.At this time, the wind also stopped, and the stench coming out of the cave became stronger. The more courageous child looked desperately into the cave, and suddenly screamed loudly.It turned out that they saw the reason for the smell inside: there was indeed something inside, but it was not a cat or dog.

Ah Jian was the first to escape, and the rest of the children rushed to the outside of the barbed wire.The rhetoric just now has disappeared. The news that a dead person was found in the cave in the vacant area of ​​Hachichome shocked the parents of these children, and several parents followed the children to the scene.After confirming it, they immediately called the police. The police car from the police station in the jurisdiction arrived at the scene first, and cordoned off the surrounding area to prohibit others from entering.Masao Ushio from the Criminal Division of the Shinjuku Police Station and his colleagues Aoyagi and Koizuka also rushed to the scene.The cave is less than 3 meters deep and has a diameter of 6 meters.Due to the danger of its existence, the district government has repeatedly issued warnings to the owner of the vacant land, but they have been ignored.Why dig this hole?Since the vacant lot has changed hands several times, no one can tell.

The police went down to the bottom of the cave and carefully observed the body.The deceased had been dead for about five or six days, and he was a middle-aged man.The blunt instrument blows to the back of his head and dented skull were the main cause of death. Since this will be the end of June during the rainy season, the corpses are stench, so we can only observe these inside. After the police came up, they tried their best to get the body up from the bottom of the cave, and then checked it carefully. After a brief examination of the body, the police believe that it is unclear whether he was killed here and thrown into the cave, or was transported here and thrown down after being killed elsewhere.

"Anyway, it's 'dark under the lights' here!" Ushio looked at the surrounding super high-rise buildings and murmured.Under such circumstances, this place has become a dead corner of "darkness under the lights".Therefore, although it is very close to the police station, after all, a homicide happened, which is equivalent to happening under the nose. The deceased was wearing a dark suit and a pair of black leather shoes on his feet.On the inside of the suit, there is a name tag with "Tarumi" written on it.His belongings may have been taken by the murderer, and there was nothing left.It seems that this person has a lot of style, but he doesn't even have 10,000 yen on him, so the police speculate that he was also taken away by the murderer.However, it seems that the murderer did not deliberately conceal the identity of the deceased.

"There are blind spots in the city, and Shinjuku is the most typical one. The murderer did it at great risk!" Qingliu said. "The crime was committed in the middle of the night, roughly in Shinjuku. There may be witnesses." "But where did the murderer kill?" Lian Zhong interjected. "It can't be considered that it was killed here. It may also be transported here after being killed elsewhere." Qingliu replied. "If it's a corpse, most people will transport it to a place deep in the mountains or the sea, no matter where it was killed, and then transport it to Shinjuku. Is this not too dangerous?"

"Long-distance transportation has the risk of contact with people, so it's hard to generalize which one is more dangerous. Anyway, the murderer knows that there is a cave in this place." Niu Wei said. "It is speculated that the deceased has been dead for five or six days. If he has not been found after five or six days in the center of such a city, it means that the murderer thinks it is safer than taking the risk to send it far away." Qingliu said . "If it is robbery and murder, generally speaking, it is necessary to transport the body to a farther place, because the murderer should be discovered as late as possible. In other words, the crime scene will not be too far from here." Oxtail followed along thought analysis.

"You mean this is a robbery and murder?" Lianzuka asked. "Of course it's not limited to this, and it's also disguised as robbery and murder. And maybe the dead person was thrown in the downtown center of Shinjuku just for the sake of disguise." Ushio seemed to be saying to himself. The nutritional status of the deceased was good, and it seemed that he was a person who had no worries about food and clothing.Judging by his state of nutrition and clothing, the life of the deceased was rich. After moving the body out of the cave, the police conducted a careful search in the cave, hoping to find evidence left by the deceased or the murderer.And the soil in the cave is also important information.

The body was moved out, but the hole was still full of stench.The police had to wear gas masks to search.The walls of this 3-meter-deep cave are almost vertical, and it is impossible to climb up with one's own strength alone. The edge of the cave is covered with weeds, and it seems that the mouth of the cave is very small, so the sun does not reach the bottom of the cave.The police brought the lighting fixtures, and the lighting was solved, but what they brought was the same steaming heat at the bottom of the cave as in summer. "It's unbearably hot!" "It's literally in hell!" "The decay of the corpse may be faster than our autopsy!" The investigator said while crawling at the bottom of the cave dripping with sweat.At this time, Lian Zhong found something in the soil. "what is this?" Ushio and Qingliu stared at Lianzuka's hand and asked. "It's a tie pin." In Lianzuka's hand was a metal fragment that reflected light under the light.It was in the dirt without rusting. "It looks like this tie clip is very expensive, isn't it platinum?" Uxo took it from Lianzuka's hand and looked at it carefully. "It's still engraved with capital letters!" "There is also a turtle-shaped pattern. Aren't K and A the pinyin prefixes of 'turtle'?" They analyzed clues around the tie clip. "I've seen this turtle-shaped pattern before." Oxtail said. "Look, isn't this the logo of the jewelry store Kinkido in Ginza!" Koizuka said. Jinguido is a famous jewelry store in Ginza. There was a case where gangsters robbed hundreds of millions of yen in jewelry. At that time, all police stations distributed relevant materials. "If it is a product of Jinguitang, you can know who the owner of the tie clip is just by asking." Oxtail suddenly became energetic. So the police immediately contacted Jinguitang.The thread on the tie clip played an important role.After checking the production registration in the store, it was proved that the entrusted producer was Matsuo Yasuko, who lived at No. 5-XX Chengcheng, Setagaya District, and she made it as a wedding present for her fiancé.And now she is married to Keisuke Asai. In this way, the identity of the deceased was found out unexpectedly.Then the Shibuya Police Station issued a notice from the "Housemaid Murder Case Investigation Headquarters" established at that time, requesting to find out whether the deceased was Yoshikatsu Tarumi, the general affairs section chief of Anko Construction Company. According to the Shibuya Department's clues, Tarumi Yoshikatsu is very likely to be related to the murder of the waitress.So they immediately contacted Tarumi Ryokatsu's family and other companies, asking his wife to come and identify the body of the deceased.The identity of the deceased was immediately proved. According to the statement of Anguang Construction Company, the deceased left work around 6 pm on the 17th.But he didn't go home and was absent from work the next day without asking for leave, and his family and company were looking for his whereabouts. The search headquarters of the Shibuya Bureau has been hit hard.Tarumi was killed.Because he was the only clue person that the Shibuya Department found after a lot of hard work.In this way, there will be no clues about any connection with Kiyoko Shimazaki.At that time, the search headquarters' suspicion of Tarumi had reached a very strong level. He is suspected to be the last passenger picked up by Kawagishi's driver three years ago, and he is also a frequent visitor to the Ginza club where Kiyoko works.Among the three people, only Tarumi is the most suspicious.Therefore, the Shibuya Department regrets the murder of Tarumi. The main concern of this search of the headquarters is whether Tarumi was killed because he was related to Kiyoko's killing, or was killed for other reasons. At this time, the police generally tended to the first reason.If the killing of Kiyoko led to the killing of Tarumi this time, then it must have something to do with the killing of Kawagishi.The search headquarters suddenly became tense. The Shinjuku Bureau, which received the notification of the investigation from the Shibuya Bureau, was shocked. The male body they found in a cave in their jurisdiction was Tarumi. So they decided to re-examine Tarumi's interpersonal relationship and living conditions before his death.Thanks to the abundant information provided by the Shibuya Bureau, the work went very smoothly. The police also compared Tarumi's hand shape data with the pinch mark on Qingzi's neck. They are basically the same, but the fingerprints cannot be confirmed to be the same. Tarumi is 48 years old and lives in an apartment in Okuzawa 1-chome, Setagaya District. There are 4 people in his family: his wife, a son who is in college, and a daughter who is in high school. According to Tarumi's wife's explanation, on the morning of the incident, Tarumi told his wife that he would go home a little later today when he left home.But he basically didn't leave the company until after get off work.In other words, after he left the company, he met the murderer, was killed, and was thrown into a cave here in West Shinjuku. The results of the autopsy proved that there was no food in the stomach of the deceased, and residues of Chinese food remained in the duodenum.Therefore, it can be judged that he died 3 to 4 hours after the meal.In this way, after he left the company, he either ate alone, or ate with the murderer. Two years after he entered Anguang Construction Company in February, he served as the company's general affairs section chief, responsible for liaising with political officials.Before he entered the company, his identity was Nagata Kazuki's financial secretary, and he was known for his spicy methods. Judging from his experience, the reason for his killing was mostly related to politics, but because he was involved in the murder of the waitress, his killing was even more complicated. According to an autopsy, the cause of death was a blow to the back of the head with a blunt instrument while he was sitting, which fractured the skull and caused a brain contusion.Other injuries have not yet been identified, but the time of death can be determined to be 3 to 4 days after the autopsy. The age is 40 to 50 years old, the blood type is AB, and there is no trace of drug poisoning. With these materials, Ushio decides to meet Asai.Asai is an employee of a large electronic machinery company. Ushio called Asai at home to ask for a meeting.When the other party heard on the phone that the police were looking for him, he was slightly taken aback, but finally agreed to meet in a tea shop in Akasaka.Asai's workplace is located in Shimbashi. "Mr. Asai, is it inconvenient both at work and at home?" Ushio murmured. "Aren't you an ordinary guest? I think it's more appropriate to meet outside my circle." Generally speaking, anyone who is interviewed by the police will always attract curious eyes from the people around him.If it is not done well, it will cause troubles on your own credit, and even lead to negative effects.Therefore, in order to protect himself, it is not surprising that Asai suggested meeting outside his circle. Ushio and Qingliu came to the tea shop at the appointed time, and Asai arrived early.He held a weekly magazine in his hand, and he looked like a cautious and quick man.The fashionable suit he was wearing was very decent, with a tie that was slightly untied on his chest, and he looked calm; and from the perspective of Uxtail, his eyes were full of vigilance. He has no tie clips on his tie.Recently, it is very popular to wear a tie without a tie clip. "Is that Mr. Asai?" Niu Wei stepped forward to say hello, and it seemed that he had already recognized the identities of the two policemen including Niu Wei. "it's me." He bowed slightly in greeting. "I'm very sorry to ask you to come out in your busy schedule." Oxtail said politely. "Ah, what's the matter? I was really surprised to be called by the police all of a sudden!" Asai stared at the two of Ushio with checking eyes.There must be rapid calculations in his head.He must have thought about it many times in the company just now.While observing the policeman's face, he took the entire store environment into his eyes. "Actually, I just want to see you." Uxo and Aoyagi sat down opposite Asai.Then Oxtail took out the tie clip. "Do you have any impression of this thing?" A vigilant look appeared on Asai's face. "It has the graphic of KA engraved on it. We asked Jinguitang, which produced and sold it, that it was ordered by your wife." Ushio's words made Asai's face react. "Ah, I remembered. This was a gift from my family three years ago, but I lost it somewhere. Where did you find it?" Asai picked up the tie clip and asked while looking at it. "Are you sure this tiepin is yours?" "Certainly. What's the matter?" Suddenly, Asai's eyes became alert. "It was found in a very suspicious place." "Suspicious place?" "Have you been to the Hachichome area in Nishi Shinjuku?" "Hachichome in Nishi-Shinjuku? I have no particular relationship with it." Asai replied cautiously.But Uxtail and the others couldn't see any special expression on him. "There is a fenced-off lot in Hachichome, Nishi-Shinjuku, where there is a cave 3 meters deep, where it fell." Oxtail just didn't say what this tie pin was with. "The cave? What's the matter with the cave?" Asai's face changed slightly. "Do you have any impression?" Oxtail leaned towards him. "It's been so long that I've forgotten it. Once I went to visit a friend who lives in a women's medical university. On the way back, I walked to the Tax Office Street. I walked into the toilet when I was looking for a park toilet. A fork in the road, but because I couldn't hold it anymore, I walked into an open space. When I finished my hand and came back to look for the car, I fell into a hole. It seemed to be more than a foot deep, but I took a lot of trouble. It took a lot of strength to climb up. It probably fell off at that time, and I have never worn a tie pin since then." Qianjing said with a smug mouth. "When did it fall, do you remember?" "My friend was admitted to the hospital in June three years ago, probably around that time?" "June three years ago?" Oxtail and the others are thinking about the meaning of this time. Tarumi was killed on June 17-18 three years later, that is to say, there was a three-year gap between the loss of Asai's tie clip and the death of Tarumi.In this way, although it is with Tarumi's corpse, there is no relationship between the two. Asai's answer was very fluent, he didn't avoid the cave where Tarumi's body was found when he fell into it. "What happened to that hole?" Asai began to ask back.There was no affectation in his expression, as if he really didn't know that the body was found in that cave. "Do you have any impression of Tarumi?" Ushio asked, while his eyes were fixed on Asai's face. "Tarumi? I don't know this person. Who is he?" Asai's face still showed no special reaction. "Didn't you read the latest paper? This man was found the other day in the cave you fell into." "what?!" Asai's expression was horrified. "That's where the tiepin was found. That's why we're here to ask you about the tiepin." "Then it has nothing to do with me. Didn't I just say that I fell into it by accident. At that time, there wasn't even a dead cat inside." It seemed that Asai was trying to shake off his doubts about himself.His expression was shaken, and his words were agitated, as if he was very dissatisfied. "No, we don't suspect you. The corpse was put in a few days ago, but this tie clip was found at the bottom of the cave, so I came to ask you specifically." "Anyway, I'm also 'dipping'! In fact, I've forgotten about the fact that I lost my tie clip." "Then let's ask again, where were you from the 17th to the next day of this month?" "It seems to be asking about my 'alibi'!" Asai's face was somewhat sullen. "We're going to ask everyone involved. Since a tie clip was found in the cave where the body was found, we don't think you have anything to do with it?" "It was three years ago that I fell into that hole, but you just said that the body was found a few days ago!" "We are just conducting a reference survey of relevant personnel, please assist us." "I've been on a business trip since the 17th of this month." "Oh, business trip? Where did you go?" "I went to the United States to establish a software center, and I have been to the United States since the beginning of June. I just came back three days ago, so I didn't read the newspaper! You can ask the company to find out." Asai's words are very positive, and it seems that the company's investigation is also the same.If he is on a business trip abroad, it is a very clear "alibi". "Understood. We asked so many things for the purpose of investigation, please forgive me. But we will store this tie clip for a while." Oxtail waited for this opportunity to say goodbye. "But it's my wedding souvenir, please return it to me after you use it." Asai said reluctantly, then looked at his watch. After breaking up with Asai, Aoyagi asked Ushio: "What do you think of this man?" "This man is innocent." "I thought so too. But did he really fall in it when he pissed?" "Although he said so, it's a troublesome cave. People like Asai can barely crawl out. Old people, children and people with disabilities must become mummies!" Oxtail wrinkled Said with a frown. On June 29, the first joint investigation meeting between Shinjuku Police Station and Shibuya Police Station was held at Shinjuku Police Station, and Tamagawa Police Station also sent Nagai to participate in the meeting.Before the meeting started, the head of the Shinjuku Police Station greeted the participants.Then the Nasu Police Department, who was in charge of the scene, briefly explained the whole process of the case, and then the meeting immediately entered the research stage. "Assuming that the killing of Kawagishi's driver, the killing of waitress Kiyoko Shimazaki, and the Tarumi Yoshikatsu incident are a series of cases, then the whole incident began with Kawagishi's murder three years ago. According to his travel records, the last A passenger's driving route was from the vicinity of Azhi to Ozawa, which happened to be where Tarumi's company and residence were located. Then Kawagishi's car stopped on the Fukasawa road, and of course he himself died there. Finally After one passenger, we believe that Kiyoko and the gangster who robbed the taxi got into the car, but there is no evidence to prove this. The evidence showing that Kiyoko and Kawagishi are connected is that there is a Kawagishi taxi company in Kiyoko's remains Calling a taxi business card, and Kiyoko went to offer incense at Chuan'an's funeral." "Tarumi hadn't entered Anguang Construction Company when Kawagishi was killed, and there was no evidence to prove the relationship between Tarumi, Kawagishi and Kiyoko. The relationship between Kiyoko and Tarumi was after Kiyoko went to the club in Ginza I know it. Therefore, I suggest that we first conduct research on whether these three events are separate events or related events." After Nasu finished introducing the situation, he said again. "Whether Tarumi was the last passenger of Kawagishi is still uncertain. In addition, if there is no relationship between Tarumi and Kiyoko at that time, then you have to think that these three cases have nothing to do with each other. Kiyoko Shimazaki There are pinch marks on the neck of the neck, even if it is close to Tarumi's hand shape, it cannot be concluded that it is Tarumi's work. Because in terms of hand shape alone, there are many people who are roughly the same. Tarumi, who has just known Qingzi for a month, will not be like this The motive for killing will soon arise. Thinking about it this way, do you regard Qingzi's murder as an independent case?" First of all, the Shinjuku Bureau put forward different opinions: "Currently there is only indirect evidence but no physical evidence. However, three months after Qingzi was killed, Tarumi, who was the focus of our work, was killed. This has attracted our attention. This is how we consider it. Is the murderer Threatening Shimazaki and Tarumi at the same time? The reason for threatening them is that Kawagishi was killed. If Kiyoko was an accomplice in Kawagishi's murder, then the murderer would think that Kiyoko's existence was a threat to him. Just like before As mentioned in the information in the paper, Kiyoko sat in the rear-end car and saw the murderer's face clearly, so the threat was established. Also, if Tarumi is the most likely Kawagishi's last passenger, he also contacted the murderer The possibility is also very high. Taking Kawagishi as the axis, isn't the contact between the murderer, Kiyoko and Tarumi Ryokatsu very obvious?" But the Shibuya Bureau also raised objections: "Wait a minute, if Qingzi is in the rear-end car, because she can't drive, the driver is still in the car. Therefore, in this case, it doesn't make sense for the murderer to kill Qingzi alone, right?" The Shinjuku Bureau recalled the opinion of the Shibuya Bureau again. "Then it can only be assumed that Tarumi is in the rear-end car." Nagai from the Tamagawa Bureau also made a statement.The attendees couldn't help being in an uproar.So far, this is a fresh view!All eyes immediately turned to Nagai. "It's not unreasonable to think that Tarumi was in the car that was rear-ended." "But up to now, haven't you discovered the relationship between Kiyoko and Tarumi?" Nasu interjected. "Just because they didn't find out, doesn't mean there is no relationship! Maybe the relationship between them was hidden at the time, and they met again in Ginza three years later?" "So, the last passenger from Azhi to Okuzawa Anira is not Tarumi?" the staff of the Shinjuku Bureau asked. "Isn't there any hindrance from him?" Nagai replied. "So the person who called later to say that something was left in the car wasn't Tarumi?" "Since there is no evidence that the passenger is Tarumi, it doesn't matter if it is him or not." "Who is it if it's not Tarumi?" "It's not clear yet, but it doesn't matter who it is. As the last passenger, he must have left something that cannot be disclosed to the world on Kawagishi's car. And he killed Kawagishi's driver in order to get it, and then Tarumi and Kiyoko Shimazaki's car got into a rear-end accident again." "In this way, there are problems that cannot be understood." "What's the problem?" "If it wasn't Tarumi, how did the murderer know about Shimazaki and Tarumi and their addresses?" "It's very simple! The rear-end car witnessed the murderer! Of course they knew about the murderer, so they were threatened by the murderer." "That's how the tail chaser knew the murderer?" "Of course, maybe the tail chaser knew the murderer before!" "But why did the murderer have to wait three years to kill Shimazaki and Tarumi?" "This is what they endured for three years, and they finally couldn't bear it, right? That's why they were killed." These explanations are really embarrassing for Nagai.However, the idea that Tarumi and Shimazaki's car collided with the murderer at the time of the murder is quite new.Nagai's view also confirms the understanding that "three cases are one case". As a result of the discussion at the joint search meeting, two views were formed on the "serial crimes" of the Shibuya and Tamagawa bureaus and the "independent cases" of the Shinjuku bureau.However, even in the Shinjuku Bureau, it is not that there is no support for "serial crimes". Although Ushio and Aoyanagi belong to the minority opinions, they are also inclined to "serial crimes". There was also a suspicious atmosphere around Tarumi.He navigates the intricacies of the financial world with ease, and there will be resentment against him from any angle.In particular, Ushio insists on the opinion based on the scene where Tarumi's body was found and the condition of the body. "The open space in Shinjuku is indeed a blind spot in the city, but since it is a city with many people, the murderer must have taken great risks. On the day of the crime, Tarumi said that he would go home later, but he It's almost on time to get off work, that is, Tarumi has reserved time for his own work. And no money was found on his body. Although it can be considered that he met the gangster after finishing his own work Attacked and killed, but if the crime was committed on the run, then the murderer should not know that there is a cave where the body can be hidden in the open space. Usually, the purpose of the crime is to rob money, or to flee immediately after the robbery and murder. What about putting the corpse in the cave? If this is the case, then I would think that the murderer's goal is not money. The murderer aimed at Tarumi's life from the beginning. As the Shibuya Bureau said, they were in The killing of the waitress was targeted at Tarumi when he was first targeted, and he was killed again. This matter is not so simple and accidental. Therefore, I think it is very necessary to find out Tarumi, especially Kawagishi and Shimazaki. clues." Oxtail said to Qingliu. Not long after the joint meeting of the three bureaus was held, Junichi Setada, accompanied by Yukiko Kawagishi, came to the Shibuya bureau to look for Sugimoto and Sato.Setada told them about the process of his investigation of Ryoko Kirihara and what they found at the scene of the car accident.At this time, they didn't know that the police were suspecting whether the Kawagishi and Kiyoko incidents were related.Because this is still police information. Sugimoto and Sato were shocked by Jie Tian's report, because these clues have not yet been grasped by the police. "So, you went to the scene of the accident where Ryoko Kirihara died." "Yes, that's what was found at the scene." As he spoke, Setada took out two rusty keys. "But even if it happened on the same night, it can't be said that Ryoko Kirihara's car accident is related to Mr. Kawagishi's case, right?" Sato retorted first. "I really can't say that they are definitely related, but they happened on the same night three years ago! And Ryoko Kirihara lives in Setagaya-ku Tori 7-chome, and it happened to be in Fukasawa where Mr. Kawagishi was discovered. On the way. What I noticed was that the time and place were very close." So both Sugimoto and Sato fell into deep thought.They have no reason to refute.From the perspective of ordinary people, there is indeed a "bystander's clear" judgment.But even if the time and place are close, it does not necessarily mean that the two cases are necessarily connected. As if seeing what Sugimoto and Sato were thinking, Setada said again: "So far, I don't think the police have investigated whether Mr. Kawagishi and Ms. Shimaji were killed. If the investigation is not carried out from this angle, there may be no results. And if the relationship between the three people is found relationship, then Ryoko Kirihara was not in a car accident, but was killed!" Then Yukiko added: "When you go to the scene, you feel that there is no way for a woman to go to that place by herself in the middle of the night. We think she must have been forced to go there by someone." "We also thought the key must have been with Ryoko Kirihara, maybe it belonged to her." Setada added another sentence. "Understood. Indeed, it would be suspicious for a single woman to go to a remote mountain in the middle of the night that has been banned. If she was forced to go, then it can be suspected that it has something to do with Mr. Kawagishi's case. Let's investigate right away!" Sugimoto said. On the same night that Kawagishi was killed, a woman who lived in Tori 7-chome, not far from the scene, died in a car accident in the mountains of Kanagawa Prefecture, and the accident seemed so incredible. The remnants found by Setada and Yukiko at the place where Kirihara Ryoko had a car accident are a great contribution to the police investigation.If Ryoko Kirihara was the owner of the rear-end car, the murderer would never let her live. But where did Shimazaki Kiyoko go then?In other words, her "position" has been arranged.She is very likely to be what was speculated at the beginning, and she and the murderer were accomplices. In this way, Tarumi was put back in the last passenger seat, and if this is the case, it is understandable why the murderer waited It took three years before killing Qingzi and Tarumi.This is because Kiyoko escaped from the murderer's control and saw Tarumi again, which made the murderer move. Due to the appearance of Ryoko Kirihara, the positions of the related parties in the incident returned to their respective positions like jigsaw puzzles, thus solving the original scattered relationship.
