i'm not a detective

Chapter 223 Just wake up the hero at the critical moment

Before DNA detection technology was widely used in the field of criminal investigation, fingerprints were the well-deserved "top criminal evidence".

Therefore, the Japanese National Police Agency has been trying to establish a nationwide fingerprint database since the beginning of the [-]th century, but this matter is too difficult. Even in Japan, there are some disputes about the privacy rights of ordinary people. Currently, the Japanese National Police Agency Fingerprints can only be collected from criminal offenders.

In other words, the fingerprints of anyone who has committed a crime are in the police fingerprint library, which can be identified by the second-generation "distributed photosensitive fingerprint comparison system in the infrared region".

The current efficiency is a bit low, and it cannot completely get rid of manual work. The system can only pick out similar fingerprints from the fingerprint database by comparing key points in the area. The final step of confirmation still needs to be completed manually.

If we want to improve efficiency, we can only wait for the further development of computer technology. It will probably not be until the beginning of the 21st century, around 2003, when all this work can be done by computers.

But now it’s almost enough. That’s how Kikuma Hisashi was retrieved by comparison. A large number of fingerprints were found in Yukio Sukada’s study, excluding the Sukada family. Among the unfamiliar fingerprints, only Kikuma Hisashi’s fingerprints were identified by comparison— — On a Western clock placed on a desk, the decorative significance is greater than the practical significance.

Wearing white gloves, Qiyuan Wu carefully picked up the western clock and looked at it repeatedly for a while. He found that the small clock was working normally and displayed the current time. Although it looked exquisite and unique, it was a bit old, but it was not an antique. The market price was about [-] yen.

Qing Jian Liuli stood on tiptoe, looked at it for a while, and asked in a low voice, "Is there something wrong?"

Takeshi Qiyuan twisted the spring, opened the back cover of the small western clock, took a look at the mechanical structure inside, shook his head and said, "I don't see any problem, it's just an ordinary ornament."

"Then why is there Kikuma Hisuji's fingerprints on it?" Kiyoshi Ruri said in confusion, "In this room, only the clock has his fingerprints on it. He must have something to do with this clock."

Qiyuan Wu put down the small western clock, looked at the study room, picked up the fingerprint comparison report to look at it, and pondered: "It may not have something to do with this clock."

"Why?" Qingjian Liuli picked up the small clock and began to study, asking.

"The desks and chairs in the study must be wiped frequently. Even if he left fingerprints, they should have been wiped off long ago." Takeshi Qiyuan made a gesture of holding the clock casually. "From the fingerprint comparison report, the fingerprints on the clock are only thumb and The little finger looks more like it is left over after daily wiping, so Kikuma Hisashi may not have only moved this one thing."

Qing Jian Liuli pondered for a while, and felt that what he said was not unreasonable.

It seems that Yukio Sukada often stays in the study, even here is the place where he chats with his friends, like tables and chairs not to say once a day, but every two or three days will definitely be wiped, fingerprints can't be saved, but This clock has a unique shape and is not a particularly important thing. If you wipe it casually, it will leave some fingerprints.

But she thought about it, and asked Qiyuan Wu: "But shouldn't you stay for more than five years?"

Qiyuan Wu nodded: "This is indeed a bit strange, there is a high probability that he has been here recently."

Seeing that Liuli was a little puzzled, Qing murmured: "Could it be that Sister Huili remembered wrongly, he is not dead? But he is still a felony, he should be in prison if he is not dead, why did he come here?"

As soon as she finished speaking, Nakano Eri, who had called to check the situation just now, came back, with a very serious face, and said directly: "I called and asked, five and a half years ago, Hisashi Kikuma did die in the detention center while awaiting trial. Here, the cause of death was also cyanide poisoning, and I have asked people to retrieve the case files from that year to see what happened."

Her memory is fine. Theoretically speaking, Hisashi Kikuma is indeed dead, and there was a lot of trouble back then.

It is not uncommon for prisoners to commit suicide. It is nothing like hanging themselves. There will always be one or two every once in a while, but suicide by taking poison while in custody is a big problem. Nothing was found, and many people were still punished in the detention center.

Now the problem is getting worse, and the dead prisoners reappeared. Could it be that they cheated to escape?
If something like this really happened, it would be impossible to make a big one into a small one, and the police officers in the detention center might end up going to jail because of this.

Qiyuan thought for a while and said, "I'll go see the victim's family first." This case is indeed a bit troublesome, so let's go and see if Hesuda's own family committed the crime first, and then talk about "resurrecting from the dead".

"Okay." Eri Nakano had no objection, "I'll go ask the detention center again to find out about Kikuma Hisashi's situation in the detention center at that time."

Let's ask from the side first, we can't reveal the possibility of Kikuma Hisashi being alive for the time being, so as not to cause other troubles.

If it is true, something big will happen to the Hirano judicial police!
She turned around and left again, while Nanahara Takeshi and Kiyomi Ruri went to the living room of the villa. Sugada Yukio's wife, Sugada Sayoko, servant Mitsuko Asae, and Sukada Yukio's daughter, Sugada Mai, were being asked to temporarily Stay here—with a female police officer accompanying them, or watching them, and the forensics department is still searching around the villa!

Sageko Sugata was in her 40s, she didn't gain weight in middle age, and she maintained a good figure and appearance, but now her face was pale, her eyes were red and swollen from crying, and she was sitting on the sofa in a daze.

Her daughter, Mai Sukada, sits in a wheelchair and sits next to the sofa, holding Sukada Syoko's hand lightly, silently sharing her grief.

The servant Mitsuko Asae looked to be in her 30s, and her face was also pale. She probably didn't expect such a tragedy to happen in the employer's house, her eyes were panicked, and she wrung her hands desperately.

She was the first to notice that Takeshi Qihara was coming, she got up quickly, and reminded: "Madam, Miss Mai, that... Qiyuan-san is here."

Takeshi Qihara is now considered a minor celebrity in Hirano. After all, he and the unscrupulous little reporter Sanae Takura posted soft articles in the newspaper to brag about himself when he was free. Recently, he has become more active. Although splashing dirty water didn't make the mysterious person X become angry and attack him, his reputation has been improved a lot.

Of course, he is not so famous that he can be recognized at a glance on the street. In fact, he is not as good as some wild idols in Hirano. The main reason is that he and Kiyomi Ruri, a pair of high school students, came to the scene of the murder a little strangely. The three of them asked the accompanying female police officer just now and knew that he was a senior consultant of the police station.

Mrs. Sugada and Mai Sugada came back to their senses, and looked at Takeshi Qihara and Kiyomi Ruri together.

Qi Yuanwu said warmly: "Madam, please express my condolences."

Mrs. Sukada's tears flowed down again in an instant, and she was choked up and unable to speak. It seemed that the husband and wife had a good relationship.Mai Sugata sat in a wheelchair, bent slightly, and said for her mother, "Thank you."

Kiyoshi Ruri also bowed slightly to return the salute, looked up and took a closer look at Mai Sugata, and found that she was about thirteen or fourteen years old, with a slender figure, wearing a clean and tidy school uniform, with black and beautiful long hair, bangs It's well groomed.

The skin is very fair and tender, the eyes are big, the eyelashes are very long, I just cried, and now the eye circles are a little red but the water is flowing, and the eyes are slightly downcast, so pitiful, just like a large Japanese doll - if you change Wearing a kimono and not sitting in a wheelchair, Mai Sukata looks like a Japanese doll in terms of appearance and temperament.

Qingjian Liuli just glanced at her, even a girl couldn't help feeling pity in her heart, a little bit of sympathy for her having to sit in a wheelchair at such a young age, and sympathy for her life to be so rough, and to be bereaved at such a young age father's pain.

Takeshi Qihara also glanced at Mai Sugata, gave her a gentle smile, then turned to Madam Sugata and said, "Sorry, ma'am, if it's convenient, I need to ask a few questions."

I have already made a record before, but Sugada Sayoko is the wife of a retired criminal policeman after illness, and he understands that it is normal for him to be questioned repeatedly when encountering a case, so he wiped away his tears and said, "Excuse me."

"You found out that Sugata-san was killed?"

"Yes, Yaguchi-san called to ask..." Mrs. Sukada choked up again when she said this, "Come to ask him if he wants to go fishing together on weekends, so I went to the study to ask him to answer the phone, but as soon as I opened the door, I saw him." When he fell to the ground, I thought he had a heart attack again, so I hurriedly asked Manzi to get some medicine, but when I went over, I found him... Later, I asked Manzi to call the police."

"Have you moved the body?"

"I'm sorry, I moved, but I didn't move too much. I heard him talk about some criminal police cases before. I just made sure that he was... gone, and then I didn't do anything else." Mrs. Sukata started again Wiping away tears, her husband's mouth and nose were bleeding, and the whites of his eyes were also bloodshot, which was nothing like a heart attack. At first glance, he died of poisoning, and there was no need to call an ambulance.

Takeshi Qihara turned his head and looked at Mitsuko Asae, the servant, and asked, "Are you the second to arrive at the crime scene?"

Asaemanko turned even paler, wringing her hands and tremblingly said: "Yes."

"Where were you before?"

"I'm washing the dishes in the kitchen." Mitsuko Asae's voice was still trembling, "I ran up when I heard my wife screaming. As soon as I entered the door, I heard my wife say that the master has been poisoned. Hurry up and call the police. I hurried to call 110. After the call 110 I went back upstairs to accompany Madam."

Takeshi Qihara took a careful look at her face, then turned his head and asked Mai Sugata, "Where was Mr. Sugata at that time?"

Sugata Mai was holding a tissue for Sugada Sakiko, and replied with red eyes: "I was not at home at the time, I was in school all day, and I only found out when I came home after school in the afternoon...that my father is gone. , and have been here with my mother all the time.”

Qiyuan Takeshi also carefully looked at her facial expression, and then asked the servant Mitsuko Asae: "Did you prepare the tea?"

Qianzhi trembled all over his body, and said in a strong nasal voice: "Yes, I prepared it, and the master took it up by himself, but...but I didn't poison it, I really didn't poison it, I have worked here for more than seven years It won’t hurt anyone, please investigate clearly, it’s really not me!”

Mrs. Sukada seemed to have just realized it, and looked blankly at Mitsuko Asae, while Takeshi Qihara nodded and said: "Please rest assured, we will definitely investigate clearly."

Mitsuko Asae took a careful look at Mrs. Sukada, and nodded with a choked voice: "Please, please investigate clearly, I won't harm anyone, I didn't do anything."

She is so scared. Sitting here all afternoon, she has already recalled a series of unjust, false and wrongly decided cases in TV dramas. After all, she really made that cup of tea. She is most like a murderer.

Qi Yuanwu comforted her again, and asked, "Has anyone been here today?"

"No." Mitsuko Asae immediately said, "From the time Mai-san went to school in the morning until the police came, the gate has never been opened."

Takeshi Qihara looked at Mrs. Sukada again, and Mrs. Sukada nodded subconsciously, proving that she was right. No one had entered this small villa before the incident, at least she didn't see or hear anyone. Outsiders have come in.

But now her sadness has receded a bit, and she has come to her senses. At that time, there were only three people in the small villa. Now that her husband is dead, and she didn't do the poisoning, it can only be the servant Mitsuko Asae. but……

But she couldn't figure out why Mitsuko Asae wanted to poison and kill her husband. After all these years together, she understood Mitsuko Asae's character, and she felt that she was not the kind of person with malicious intentions.

There are only two suspects, and there is no one else!
She asked Asae Mitsuko blankly, "Is it really not you, Mitsuko?"

"It's really not me, I won't harm anyone." Mitsuko Asae became more and more frightened, looked at Mrs. Sukada, and said tremblingly, "Isn't it you, madam?"

Eri Nakano and the others will definitely not inform them of the investigation of the case. These two people only know that Yukio Sukada died of poisoning, and they are instinctively suspicious of that cup of tea. I can't guarantee whether Sugata Sayoko added some ingredients while she was not paying attention at that time.

After all, there were only two suspects, if it wasn't her, it must have been Sugata Syoko who murdered her husband.

Mrs. Sukada was stunned for a moment, and said in pain: "How could I do that kind of thing, we have been married for more than ten years..."

Asaeda Manko opened his mouth and was speechless for a moment.

She felt that there was no one else but Sugada Sayoko, but...she couldn't think of why Sayoko poisoned her husband. Usually, the relationship between the two seems to be very good, and Sayoko's character doesn't look like he has the courage to kill someone. .

Mai Sugata sat in the wheelchair, held the hands of the two people respectively, and said with tears, "Mother, Aunt Manko, please don't do this. I believe it's not you, there must be other reasons."

Qiyuan Wu sat aside and looked at the three people, and said softly: "Yes, the facts are not clear now, and there is no point in mutual suspicion. Please trust the police... or me, I will investigate clearly, please don't worry."

Mrs. Sukada and Mitsuko Asae nodded with tears in their eyes, and choked up in unison: "Then please."

Takeshi Qihara asked about Yukio Sugada's daily life, his friendship, and the financial situation of the Sugada family, and Mrs. Sukada and Mitsuko Asae answered honestly.

Yukio Sukada returned from illness, and had heart disease, but he didn’t stay at home anymore. He joined several clubs, participated in various activities, from fishing, growing flowers to playing chess and reading. From time to time, I also do some public welfare activities, and I have a lot of hobbies.

The financial situation of the Sugatian family is also very good. The family has a strong family, no luxury expenses, and no one to gamble or whore. In terms of money, there is not much trouble.

Money is not a big problem, and the family atmosphere will be more harmonious. There will be no conflicts in life, including servants.

Takeshi Qihara asked carefully, but couldn't find any questions. After pondering for a moment, he asked again: "In the past one or two months, who has visited Sugata-san and been received by Sugata-san in the study?"

"Shikatori-san, Shidou-san, Yaguchi-san, Takamiya-san, Ito-san..." Mrs. Sukada immediately reported a list of people. Yukio Sukada has many hobbies and friends, and old colleagues from the past will come to see him occasionally He chatted, "They usually go to the study to chat, sometimes four or five come at a time. There should be some more, but I can't remember the time clearly."

"There are also Ota-san, Seta-san, Yasawa-san, and the police station will occasionally send people to visit..." As a servant, Mitsuko Asae added five or six people, some of whom had eaten at Sugata's house or I stayed overnight.

"Uncle Guba and Uncle Gujia also came here." Daughter Mai Sugatian also helped recall, "Uncle Gujia often came to play chess with Father, and Father Futase of the church also brought people here."

There were quite a few people, Qiyuan Wu turned around and asked someone to bring a pen and paper, and said: "Then trouble the three of you to recall and make a list!"

Whoever poisoned it has not been found out, and the matter of Hisashi Kikuma's "resurrection" has become more and more suspicious. He must have been to Sukada Yukio's study in the near future—fingerprints also have a shelf life, and they will gradually fade away with time. Decomposition is blurred, very much depends on the environment and attached materials.

Under the premise of no harsh objective environment (rainstorm, sun exposure, etc.), man-made damage (erasing, covering, etc.), fingerprints can usually exist naturally for three days to several years depending on the material.

Like pressing on the indoor wall, the fingerprint may be unrecognizable within a day or two;
If materials such as glass and mirrors are changed, the shelf life of fingerprints can be extended for weeks or even months;
If the paper is changed, the time can be longer, it may be half a year to several years, depending on what kind of paper it is - if fingerprints are caught in a book, or a page in a document, or placed in an insurance policy In the cabinet, it is possible to identify it in two or three years.

At the same time, it needs to be divided into people. Some people have sweaty hands or high oil secretion on their hands, and the shelf life of fingerprints will be extended simultaneously.If it is stained with viscous liquid such as blood, it will be safer, and it can still be used to identify identities for several years or even ten years.

The shelf life of fingerprints needs to be analyzed on a case-by-case basis. In this case, the case of the small western clock is made of smooth metal, and it is located in a study room that is not too ventilated. Takeshi Qiyuan estimates that the shelf life of fingerprints should be within two months, so by the way Ask who has been to the study in the past two months, but there is no need to explain in detail.

The three members of Sugata's family had no objection and began to write the list, while he got up and walked to the kitchen of Sugata's house to continue the investigation.

Qingjian Liuli was following behind him, still wondering who had poisoned him. There were only two suspects at the moment, but she listened for a long time and tried her best to observe the situation, but in the end she didn't find anyone who was more suspected.

The servant Mitsuko Asae was very scared, but that kind of fear didn't feel like a guilty conscience, it was more like frightening herself, fearing that she would be wronged.

Although his wife, Sayoko Sugata, was not afraid of being wronged, she seemed too sad to think of it for a while, or she didn't think she had the possibility of being a murderer at all, and she didn't look like poisoning her husband. .

Not to mention her daughter Mai Sugata, she said that she was in school, and a large number of classmates could prove that she couldn't tell such a lie that could be easily exposed, and the case had nothing to do with her.

If an outsider committed the crime, the window of the study room was locked from the inside. Both she and Takeshi Qihara checked and found no problem. The only way to enter and exit was the study door, but the two women were on the first floor, one was in the living room and the other was in the kitchen. It is impossible for them to go from the first floor to the second floor without noticing...

Or it's time to check other rooms on the second floor. Maybe someone sneaked in through the windows of other rooms at the back of the small villa, went straight to the second floor, and entered the study to feed Yukio Sugata poison.

But it's hard to make sense, Sukada Yukio is not a three-year-old child, someone sneaked in to give him poison, or give him a piece of candy, a piece of cake, he can't just eat it without saying a word, right?

Or knock him out and force feed him?But the desk is behind the window and the door is facing. It is impossible for someone to open the door without finding it. Let alone a senior former criminal policeman, it is impossible for ordinary people to be successfully attacked.

Moreover, it can knock people out, and it is completely unreasonable to feed poison. Wouldn't it be good to just stab a few times?
The key lies in how the murderer poisoned it!
Qing Jian Liuli was a bit overwhelmed with thinking, and he didn't think of a possible method, so he could only rely on Qiyuan Wu to figure it out by himself, and he would say a few more words when he had a preliminary idea.

As the heroine, you don't have to do everything yourself, you just need to wake up the hero at critical moments.

Hope he finds something out!
