It took Takeshi Qihara nearly a day to go through all the cases from eight or nine years ago, and in the end there was only one suspected case - the Songtang University Injury Incident.

Nine years ago, there was a small animal abuse and killing incident in Hirarano Songtang High School, the rabbit raised in the school was attacked at night and was killed by hanging upside down in front of the cage, which caused public outrage in the school for a while, but killing two rabbits is not a criminal offense, and the reason why the matter rose to a criminal offense is that the students themselves found out the murderer, which caused a wounding incident.

At that time, it was rumored in the school that the person who abused and killed the little rabbit was a sophomore in high school, Xingqian Gong, a boy who had just turned eighteen, but how did the students determine that Xingqian Gong was the murderer, it was not written in the file, but Xingqian Gong was naturally isolated, and everyone felt that he had a psychological problem, and began to alienate him and talk about him behind his back.

He endured it for about half a year, and finally broke out when someone asked him in person, "Xingmae-kun, did you wet the bed today", and it caused a burst of laughter - "bedwetting" is an extension of the line in an American drama in the late seventies, in which it is believed that "perverted serial killers" have the experience of bedwetting, arson, and abusing small animals, which is a rough summary of the early days of the psychological portrait technique of committing reason.

At that time, the American drama became a bit popular after the introduction of the book, and there were similar things around him, so Xingqiangong's classmates began to "joke" with him about "bedwetting", and by the way, they "reminded" each other to be careful not to set fire to the school.

Then Yuzen Bow suddenly broke out, and there was a fierce conflict with the small gang that made fun of him, and he was so angry that he chased them like he lost his mind, and finally caused a boy in the same grade to roll down the stairs and fall into serious injuries, plus several minor injuries, directly turning the "joke" into a criminal case.

However, there is nothing difficult about this case, there were many witnesses during the fight, and Xingqian Gong also directly pleaded guilty, and it took less than three days from reporting to sending it for inspection, and finally Xingqian Gong was identified as having depression, conjecture, mania and anxiety and other mental illnesses, and was exempted from criminal prosecution by the prosecutor and entered a psychological sanatorium for psychological rehabilitation treatment - the so-called psychological sanatorium is actually a mental hospital, but it has a nice name, and I say that I care more about other people's opinions, and often like to name similar institutions.

As for what happened to Xingqian Gong, there is no record in the police file, and the words "exempt from criminal prosecution" were added when the case was closed later, and then all the records and evidence related to the case were ......

In fact, there is no evidence, the photos of the rabbit being killed were taken by students of the school news agency, and the criminal police who handled the case at that time took it back when they understood the reason for the fight, and finally threw it into the box with other files, and directly sealed it into the file, and the case was finished.

Kiyomi Ruri accompanied Nanahara Takeshi to rummage through the box, and by the way, he acted as an "eye", carefully depicted the photo of the "tragic death of the rabbit", and then asked carefully, "How is it?" Do you think he could be the 'Tuesday Night Killer', which seems to be a bit in line with Professor Hirakawa's speculation, at least he has a history of mental illness. ”

She has basically made up the crime in her brain, but fortunately the former bow has a mental illness, and she can't control the torture and killing of the little rabbit, and then she is regarded as an outlier by her classmates, and is further stimulated, and finally completely out of control and embarks on the road of serial killer.

Specializing in killing women, it is very likely that the girls found out that he abused and killed the little rabbit, and they also participated in the daily ridicule of him, and he held a grudge - the private Yuying University also has a small breeding garden, raising sheep, chickens, rabbits and other small animals, basically the girls are in charge, and it should be similar to come to Songtang University.

"Mental illness?" Nanahara Takeshi wasn't as sure as her, but he still nodded, "But it's really suspicious, at least you should ask the sanatorium about his situation." ”

Taiji Okuno and Hidaka were also in high spirits, and felt that Kozen Bow should be checked carefully, so Hidakaji immediately got up and went to make a phone call, while Okuno Taiji and Kiyomi Ruri restored a few rooms to their original state and re-stacked a large number of "file boxes".

Kiyomi Ruri was glad to find the clue, but while she was busy working, she asked Taiji Okuno curiously, "Officer Okuno, didn't anyone pay attention to this case seven years ago?" ”

She felt that this photo of the "tragic death of the rabbit" was an important clue, but it was thrown in the basement for so many years, and no one came to look at it?

Seven years ago, Taiji Okuno didn't become a policeman, so he didn't know what was going on, but after thinking about it, he said helplessly: "Probably this case is too inconspicuous, no one cares about the reason for the fight, in fact, only one student fell and was seriously injured, and no one even died, and it also involved school affairs, the case is still very simple, it should be handled casually in the second division of life safety, and the search department may not know at all, and it is with' Tuesday Night's Killer's crimes were more than two years apart, and it is impossible for anyone to associate the two cases together if they were not specifically searched. ”

After a pause, he went over to look at the label of the file box of "Songtang University Wounding Case", and came back and added, "The person who handled it is a senior named Touchuan, I have never heard of this surname, and I may have retired or transferred away a long time ago, and I may not have participated in the last big search." ”

There are too many possibilities, how can there be nearly a thousand cases of wounding in a year, sometimes a criminal policeman has to deal with two or three similar cases a day, let alone two years, it is possible to forget it after a month, the devil knows what was going on at that time.

As for why the last search headquarters didn't come to turn over the old case like Takeshi Nanahara, it is estimated that there is no brain circuit in him, I didn't expect that the perverted serial killer should have a growth process, after all, Hirano has been there for so many years, and there is this serial killer, everyone has no experience, and they don't know much about serial killers.

The two of them chatted and restored the "archives" to a mess, only to be more chaotic than before, and Hidakaji also ran back at this time, reporting bad news and good news.

The bad news is that the mental health care home called Kinoshima closed down more than five years ago due to poor management, and the patients were transferred to the hospital and triaged, and all the medical staff looked for other jobs.

The good news is that it was easy to find Kozen's parents, and they changed their phone numbers when they moved, but Kozen's father didn't change jobs, and it was still the same as the previous registration, and he called the factory and asked him about his current address.

That's okay, it's so-so, Nanahara Wu smiled: "Then let's work overtime and go to Xingmae's house first." ”

Taiji Okuno had no opinion, but just reminded: "Do you want to inform Miss Nakano and ask her to list Kozen as a suspect and investigate it comprehensively?" ”

Nanahara Takeshi thought for a while and said with a smile: "The situation is still unclear now, it's too early to inform her, just wait!" ”

At present, I really don't know what the situation is, and it is unstable to say, and if it is true, he will also take the credit, so that it is convenient to increase the price next time.

…………

Half an hour later, the four of them appeared in the living room of Kozen's house and met Yuzen's parents.

This is a couple in their fifties, named Yukizen Hiroshi and Yuzen Motoko, the family conditions are okay, barely middle-class, but both of them look a little older than their actual age, and their hair is a little gray.

Taiji Okuno came forward to inquire, and as soon as he sat on the sofa, he asked directly: "Kozen-san, we came this time to find out about your son Kozen Bow, where is he now?" ”

Hiroshi Kozen is a factory production line manager, and he seems to have a somewhat resolute and direct personality, so he immediately asked, "Why do the police want to know about his situation?" ”

Taiji Okuno's expression remained unchanged: "It's just a routine investigation, and I also ask Kozen-san to cooperate, after your son was admitted to the Kinoshima Psychological Sanatorium for treatment, was he discharged or transferred?" Where are the people now? ”

Hiroshi Kozen was silent for a while, and sighed: "He was discharged from the hospital, he was discharged after more than a year of psychological treatment, but after he came back, his mental state was very bad, and he had misanthropic tendencies, and we were very worried, so we sent him to a family in Tokyo again...... The sanatorium went to continue the treatment and is now there. ”

Kiyomi Ruri was surprised: "He's been in Tokyo all these years? "That's over, you should find the wrong person, the murderer is not him, run for nothing.

Yuzen Hiroshi glanced at Ruri Kiyomi and couldn't figure out why she was here, but he didn't care about it, so he just nodded silently.

Taiji Okuno immediately asked, "Which sanatorium is he in Tokyo?" ”

Hiroshi Kozen said the name of a private psychiatric hospital, wrote down a phone number by the way, and sighed: "Although I don't know what you are looking for him for, you can call this number to verify, you can call now, it's okay." ”

Taiji Okuno was really not polite, and immediately borrowed the phone of Kozen's house to dial this number, and the phone was connected after a few "beeps", and a middle-aged woman's voice came from inside: "Hello, please speak." ”

Taiji Okuno didn't report his identity as a policeman, but in case Yuzen was innocent, it was easy to cause trouble to the other party, so he politely asked, "Is it Miya Shiraku Spa?" I would like to know about the situation of Kozen Bow. ”

"Kozen-san's situation?" The voice on the other end of the phone was a little nervous, "Sorry, we can't just reveal patient privacy. ”

"I just want to know if he's been treating you all along?"

"This ...... Yes, he has been recuperating with us for many years. The female voice on the phone replied, and asked carefully, "Who are you?" ”

Yuzen Hiroshi stepped forward to take the phone and began to talk to the other side, and finally said a few words "That's good, that's good, it's really hard for you" before hanging up the phone, turned his head to Okuno Taiji and sighed: "Xiaogong's condition hasn't changed much, and he still needs psychological counseling and medication." ”

"Sorry to interrupt." Taiji Okuno and Hidakaji got up and bowed slightly, ready to say goodbye, which was obviously the wrong person, and Kiyomi Ruri also bent down embarrassedly, and was about to take Takeshi Nanahara's hand and lead him away, but when he stretched out his hand, he was empty.

She quickly turned her head to take a look, and found that Nanahara Wu didn't know when he disappeared, and hurriedly said, "Have you seen Nanahara?" ”

Everyone turned their heads to take a look, only to find that Qiyuan Takeshi was really a blind man, and he was stunned, Nanahara Takeshi walked out of the corridor in the direction of the kitchen with his support for the wall, and said with a shy smile: "I'm sorry, I wanted to go to the bathroom, but I accidentally got lost...... But it seems a little strange, I found a plate next to the rice cooker, there seem to be a few side dishes on it, there is a guest at home, are you going to deliver food to him? ”

Fortunately, Suzi's face turned pale instantly, it was already evening before, she was indeed preparing dinner, and she had prepared more than half of it, just waiting for the meal to be cooked, but the group of people from Nanahara Takeshi came too suddenly, she didn't have any mental preparation, and forgot to hide the delivery plate.
