Conan: Open the Door, I’m a Policeman

It's a new day again, the sky is clear and the air is clear and the wind is gentle, but it's a pity that Shui Jianyue's mood is not very sunny, not only because there is work to do today, but also because he sees people who don't look like he sees.

That's right, Mizumayuki saw Conan at the crime scene again. Well, the Mouri family is here.

The deceased, Shinde Yoshiki, was a doctor who opened a clinic in his own home. Today, Kogoro Mouri seems to be bringing his family to see a doctor. I don't know if I haven't read the medical treatment. Anyway, people were killed by Conanke.

The cause of death was electric shock. At that time, the deceased was taking a bath in the bathtub, and the power went out in the middle. Then, when the call came, the deceased had been found dead in the bathtub. Conan and Mouri Kogoro found a shaver with a charging cable in the bathtub.

Yoshiki Shinide's son was also a doctor, and he performed first aid measures such as cardiac resuscitation for the deceased, but failed to save his father.

Mizumayuki glanced at Conan casually, and then gestured to Mo Lilan with her eyes. In previous cases, Mo Lilan had already taken Conan out at this time with interest.

Putting on gloves, Mizumayuki took the electric razor with a little black mark from the forensic staff, and gently pushed the button of the razor, the razor started to work, and it made a squeaking sound. With a smell of mush, it seems that a short circuit has indeed occurred, and there is a little fault.

"I feel that the sound and electricity are quite strong. Does the deceased really need to use it while charging? Was it electrocuted or killed by a fall?" Mizumayue couldn't help but muttered, the autopsy results have not come out yet, the deceased's head hit the back A pit is not fake, and it is not necessarily a crash.

"The cause of death must be electrocution! You see, there are also electric spots here!" A stinky little devil's voice sounded at the foot of the moon in the water.

Um? Why is Conan still here? Didn't Maurilan take him away? Shui Jianyue was stunned for a moment, and subconsciously glanced at Mao Lilan first.

Unexpectedly, Mao Lilan was staring at the deceased's son, Xinchu Zhiming, and didn't notice it at all.

"You talk too much! Go out and don't make trouble." Before Mizuma Tsuki attacked and threw Conan out in person, Uncle Mouri punched Conan on the head and kicked him out.

"I'm sorry, Officer Shuijian, I usually don't discipline this kid enough, and I'm naughty again." After kicking Conan, Uncle Mori turned around and smirked to smooth things out, and he didn't forget to tell his daughter: "Xiao Lan! Take care of that stinker. boy!"

However, it was Mizumayuki's expressionless face that faced him, "Could you please leave the scene, Mr. Mouri? If we step on the scene, we will be more troubled."

"Uh... well."

After sending the detective away, Mizuma Yue carefully observed the electric spot on the calf of the deceased mentioned by Conan.

The formation of current spot is due to the contact of the charged conductor with the skin. When the current passes through the intact skin, a special skin damage is produced at the contact. To put it bluntly, it is similar to burns, but not the same as burns. Because it reflects the shape of the contact part between the conductor and the human body, it can be used to infer the contact surface of the conductor, that is, the shape of the murder weapon, so Mizuma Tsuki used this to tell the forensics department and the autopsy department.

However, Shui Jianyue vaguely remembers that when the skin is immersed in charged water, due to the small skin resistance, the large contact surface of the conductor and the short contact time, the typical current spot is generally not formed, and only simple skin burns, Changes such as epidermal peeling and subcutaneous hemorrhage, and sometimes there is no change at all. Is it a coincidence or some kind of secret that the electric spots on Shinde Yoshiki's calf are happening? Mizumayue glanced at the door subconsciously, thinking that there must be something hidden in this kid Conan.

Of course, even if there is no current spot, it is easy to determine the cause of death of the deceased through forensic identification: electric shock.

The reason for the formation of the current spot is also easy to explain: it is not easy to form the current spot when the electric shock time is short, but according to Kogoro Mouri, the razor was soaked in the water until they walked into the bathroom and found the deceased, During the period, the deceased has been in the state of electric shock, not to mention the current spot, it is not surprising that it is familiar.

So the circuit needs to install a circuit breaker! Tsukune Mizuma silently criticized in her heart. Last month, the Metropolitan Police Department underwent a major circuit renovation, one of which was to replace the original fuse circuit breaker with an air circuit breaker.

However, although the government has been encouraging citizens to install circuit breakers in their homes, there are still many families without protection measures such as new monks. If circuit breakers are installed on the roads of new monks, perhaps the shock time of new monks will only be momentary. It won't make the rescue ineffective.

Of course, this assumption is only based on accidental electrocution, if someone did it deliberately...

After a while, Mizumayue rubbed his eyebrows, this case was a bit tricky, and he felt at a loss. Ordinarily, I can't see anything at this step in case handling. The next step is to investigate the scene, analyze some suspicious traces, or expand the search scope. There is no point in looking for clues, there is something more important to do. To put it more vividly, Mizumayuki's situation is that it feels boring to handle the case, but there is something that I wanted to do before and I can't get up now.

To get rid of the distracting thoughts in her heart, in order to find something to do for herself, Mizumayue sorted out the relationship between everyone present and the deceased to see if anyone had a motive for committing the crime.

First pick acquaintances, let's start with Maori Kogoro. First of all, he is a senior in the police industry, familiar with the process, and everyone is familiar with it. Maori Kogoro can also clearly explain what he needs to say and give others a good start, which is equivalent to Set an example for those in the back.

It took some time for Mizumayuki to figure out what happened before and after.

The deceased Shinde Yoshiki is the center of the family relationship of the new monk and the master of the family. He has a son, Shinde Chiaki, and both of them are engaged in medical work. It is the school doctor of Tedan High School, but as the first graduate of Tokyo Medical University, being the school doctor should be to prepare for taking over the clinic of Shinzo Yoshiki, but this does not constitute a motive for murder, after all, the clinic is not enough. People can't wait and take risks.

The hostess Yoko Shinide is the stepwife of Yoshiki Shinide, which is the stepmother of Tomoaki Shinide. It is the best friend of Xinchu Zhiming's biological mother Xinchu Qianjing. Qianjing married a new monk not long after his death, but the relationship with Xinchu Zhiming and Xinchu Qianjing's mother Xinchusan is quite harmonious. Yoshiki Shinide lives in a disorderly manner, and has a lot of opinions about maintaining improper relationships with mostly female patients - as long as it is his wife, he will have opinions, and it may not necessarily constitute a motive for murder.

Shinju San, Shinju Qianjing's mother, is not particularly fond of Shinju Yoshiki, and it is not clear whether it constitutes a motive for murder.

Baobenguang, a newly ordained helper, is characterized by clumsiness. If there is any conflict with the deceased, he is often scolded for making mistakes. Today, he is yelled at by the deceased that if he makes any mistakes, he will be kicked out.

Maori Kogoro and his family came to get the diagnosis results. Today was the second time he saw the deceased. He was left to eat because the deceased respected him.

Mizumayuki patted the sorted information on the table, a little bit reluctant to read it, and felt very irritable.

Is it ignored? Or because of something else? If it goes on like this, will the case be solved by that dead kid Conan? Mizumayuki glanced at Conan not far away in depression.

However, it was only after this scan that Conan seemed to be in no mood to solve the case like him, staring at Ma Lilan blankly. .

Mizumayuki has seen this kind of light. When she was in high school, the female classmates in the class saw this kind of light in their eyes when they saw something they liked.

Eh? Is it a complex multi-angle relationship? Mizuma Tsuki remembers that Detective Conan should be a detective story rather than an urban soap opera, right?

Having said that, if there is any complicated relationship between Maorilan and Shinide Tomoaki, Shinide Tomoaki should also be a main character in the original work, right? Will I be irritable about him?

I don't know if it has something to do with psychological effects, but Mizumayue felt less annoyed all of a sudden, picked up the document and looked at it.

After watching it for a while, Suimayue received the news. No valuable clues were identified at the scene of the crime. I wonder if she had a premonition, but Suimayue didn't find it strange at all.

As usual, the order to expand the search range was arranged, and Mizuma asked a few capable leaders to hold a small seminar.

The first step is to sort out "what happened", and Nakamura Kenichi expressed his opinion: "First of all, there was a power outage, during which the deceased's razor fell into the bathtub - in fact, my personal opinion is that maybe it was just an accident , in fact, there is no evidence that this is man-made, is there?"

Noticing Mizumayuki's stern gaze, Nakamura Ken shrank his neck and continued: "After the power outage, the people in the living room are the Maori family, Shinichi Tomoaki, Shinichi Yoko, and they can alibi for each other. Izusan was unable to provide the abnormality certificate upstairs at the time, and Hiroko Baoben went down to check the switch at Yoko Shinichi's request, and after the power supply was restored, Yoko Shinichi and Hiroko Baoben found the deceased in the bathroom together."

Mizumayuki nodded and added: "There are still some details, although Yoko Shinichi and Shinzo San confirmed that the deceased liked to shave in the bath, but the rechargeable shaver is still full of electricity, so the deceased should not have enough electricity. It needs to be charged and used. The route to check the switch does not go through the bathroom, and Yoko Shinide mentioned that it took a long time to check the light.”

"So Ms. Hikaru Homoto is the most suspicious?" asked the silly Takagi Shibu.

"On the contrary, the biggest suspect is Shinichi Yoko." Kawasaki Hideki said.

"Ah?" Takagi was stunned again.

"Because you think Baobenguang's suspicion was guided by Yoko Shinichi's words." Mizumayuki explained slowly: "When the case was in the dark, forging an alibi couldn't be easier. Son's motivation is greatest, and—"

"Her alibi is too obvious, there is a feeling of being prepared." Kawasaki Hideki said.

"Okay, let's first lock the new Yoko and try it according to the pre-guessing deduction method, and solve the first problem, the method of alibi."

"Pre-, pre-guessing deduction?" Takagi is a newcomer, and he has not received much education (roaring) education (roaring) from Mizuma Yue, and he subconsciously repeated the content that he had never heard in the criminal police school.

"Oh, by the way, you came later, and I didn't teach you about this." Mizumayue suddenly realized.

Takagi feels uncomfortable and wants to cry, he has been here for almost a month...

"It's just a review, who will talk about the content of the pre-guessing deduction method?"

"I'm coming!" Fujiwara Sakagi volunteered: "The pre-guessing deduction method means that when there is no evidence with a clear murderer orientation, if the number of suspects is small, you can first assume that a person is a suspect. The method of this person's crime is to figure out the criminal process and find out the possible hidden evidence."

"The summary is very incisive. I'll give you a task to find out why it took so long to turn on the power."

"Me? I'm from the forensics department? Why am I?" Fujiwara Sakagi was a little confused.

"Is it a reason because you talk too much?" Mizumayuki rolled her eyes, "If you can't, I will ask Takagi to be your assistant."

Fujiwara Sakagi collapsed a little. It was Mizumayuki who asked him to talk about the pre-guessing deduction method. How could it be that he talked too much, so he took Takagi to find Hiromoto.

Mizumayuki went to the electric switch in the kitchen to study how the murderer could achieve the blackout at the required time. To be precise, he was studying how the new Yoko achieved the blackout.

Preliminary inspection did not find any obvious traces. Judging from the time, Yoko Shinju should not have time to return to the kitchen to eliminate traces. The testimony of Baobenguang also indicated that he did not notice anything special when he turned on the power.

Soon the people in the forensics class disassembled the electric switch, all of which are normal ordinary lines, full of dust and written on disrepair and not enough hands and feet, so remote power off or timing power off through electronic components is excluded. , that is the timer.

Hideki Kawasaki proposed whether to use dry ice to design the organ, because dry ice sublimates directly into gas without leaving traces, and was rejected by Mizumayuki, on the grounds that dry ice storage is not easy, and the method of new Yoko should be to wait for today at any time This kind of opportunity to have people other than family members as guests can be used as "witnesses", and the agency should choose simple and common things that will not arouse curiosity if they are seen in advance.

"What would that be?" Nakamura Kenichi asked.

"No matter what it is, it is absolutely useless to stand here stupidly," Mizumayue said with a hint of dissatisfaction: "Still here stupid? Call a group of people from the forensics class and focus on searching here first! No matter how subtle the technique is , always leave traces, tell them all to keep snacks, or the same sentence: 'Even if you see a dead cockroach and a dead mouse, ask me if this family was killed by them!'" One sentence compares One sentence was high-pitched, and the last sentence was simply ordering the forensic officers throughout the house.

"Hi!" Nakamura Kenichi, Kawasaki Hideki, Chiba, Shinobu, and the others were startled, and immediately dispersed as birds and beasts to execute the order.

After the others left, Mizuma held her chin and looked at the switch, a simple timing device, the most common thing in the case of Mizuma over the years is candles or ice cubes, but the burning of candles will produce light and candle tears, water after the ice cubes melted The stains did not disappear as easily as the prisoners thought.

This time, however, there were neither water spots nor paraffin vapour deposits found nearby—evidence of burning candles.

Mizuma Yue took a small portable high-power magnifying glass and carefully observed the switch, but still did not see any clues.

In fact, it is not that there is nothing at all. The switch of the new monk is embedded with a small section, so there is a small platform under the switch, only about one centimeter wide.

And on this platform, there are two dotted traces that meet about three centimeters together. It is the only special thing that Mizumayue sees, it's just...

I took a Polaroid camera and took a photo of the two little white dots. Without professionalism, Mizumayuki took off her gloves and tapped it a little further away with her fingernail. Almost, it is simply a trace that is easy to leave on the cement.

Mizumayuki was caught in a war between heaven and man: on the one hand, he felt that this kind of trace was too common, and there was no effective way to identify when it was left, so he wanted to leave it alone; The dark under the lights of self-criticism, even if it is a very common trace, cannot be easily ignored.

But it's one thing to teach others a lesson, but it's another thing if you can do it yourself. After thinking about it, Shui Jianyue is not willing to really ask this family to ask if she knows there are two small points here... ..

Although these small spots can be seen with the naked eye, if they hadn’t been noticed with a magnifying glass before, even Mizumayuki would not have discovered them, not to mention that such traces will disappear without a trace just by wiping them with a hand or something. , I feel like asking about this trace makes me want to ask, "Do you know that these two dusts fell here?" The same.

The inexplicable Mizuma Yue suddenly felt that if it was Conan, she might not hesitate to ask such a "stupid question" by dragging a certain young lady's skirt.

strangeness? why skirt? Mizuki's mind suddenly jumped out of the boundless frontier. It seems that she often saw Conan's behavior in her past life's memory?

On the other side, Fujiwara Sakagi bravely went to find Hiromoto, followed by Takagi Shibu.

Taking a deep breath, Fujiwara Sakagi said: "Miss Baoben, can I ask you a question?" It was just a hesitant look and a hesitant tone that really didn't want to be an inquiry, more like a young man accosting a girl , at least in the eyes of someone who is somewhat disrespectful.

Mouri Kogoro, who was sitting in the living room with the new monks and waiting, joked to Fujiwara Sakagi: "Young man, be careful when you desert at work, the Mizuma Police Department will take care of you!" He remembered that Fujiwara Sakagi was in the forensics department, and he never imagined that Mizuma had a nerve Send him to inquire.

"It's the work problem that doesn't bother Mr. Mori." Fujiwara Sakagi politely responded to Kogoro Mori's joke and asked Hiromoto: "Ms. Baomoto, according to the general opinion of everyone, you went to the kitchen to check the switch than normal. The situation is a lot longer, can you explain why?" After being joked by Kogoro Mouri, it became easier, at least he was able to explain the problem smoothly.

After hearing Fujiwara Sakagi's question, Hikaru Baomoto became even more nervous and hesitantly said, "There's no reason, it's just, it's just a little thing anyway, it wasn't me who killed Mr. Shinichi."

Fujiwara Sakagi said with a wry smile: "No murderer will admit to killing someone at this time. The police can't believe you are innocent just by saying so. Only by clarifying the reason for the delay can we cancel the suspicion of you. "

There is a type of person who likes to use a smiling face to hide his nervousness when he is nervous. Fujiwara Sakagi is such a person.

"It's just a matter of privacy, it really has nothing to do with the case..."

"Miss Baomoto!" Fujiwara Sakagi's "little follower" Takagi finally couldn't bear it any longer, and stood up with a stern face.

————————————————————————

Origami's broken thoughts: It hurts, I really want to write the whole case in one chapter, but it took 5,000 words for some inexplicable water to get half of the content... Could it be that I haven't typed the words for too long?

It hasn't been updated for a month... Surprisingly, not only has the collection not been greatly reduced, but on the evening of the 24th, it has broken through the 10,000 mark. What a wonderful Christmas gift...

I finally finished the exam... But it seems that I still failed. It's still a big failure. I guess the make-up exam can't save me...

The following is the Baidu Encyclopedia handling of the current spot, students who don't like it can skip it.

The current spot, also known as the current imprint, is a special skin damage caused by the Joule heat and electrolysis generated at the contact when the charged conductor is in contact with the skin and the current passes through the intact skin. The thicker parts of the stratum corneum of the skin have high resistance and generate more heat when the current passes through, which is easy to form typical current spots. There are usually one or two current spots, or more than one. In one case of homicide, the deceased suffered more than 50 electric shocks to his head and neck. The common sites are the fingers, palms, forearms, soles, chest, shoulders, side of neck, calves and dorsum of feet. The current spot mostly occurs when the electrode contact surface is small. When the temperature generated by Joule heat is less than 120°C, the current spot formed is the most typical.

The typical current spot is generally round or oval, 5-10mm in diameter, grayish-white or grayish-yellow, hard and dry, concave in the center, slightly uplifted around, bluntly rounded edge, like a shallow volcano, and may have a hyperemia ring around it. The surrounding tissue is clearly demarcated. The bottom is flat or fissures exist, sometimes with deposits of ash and dissolved metal debris. Sometimes tubular pores can be seen, and the surrounding walls are carbonized. Blisters can be seen around some current spots, which are easy to rupture, resulting in epidermis loosening, wrinkling or peeling. Galvanic edema may sometimes occur in the skin around or in other parts of the galvanic spot, and the edema is pale. Sometimes galvanic edema occurs throughout the limb.

The current spot can be as small as a needle, as large as a few centimeters in diameter or more.

The current spot has various shapes, such as furrow shape, strip shape, arc shape or irregular shape. If the long axis of the wire is touched, the current spot is in the shape of a line or groove; when the end of the wire is contacted, the formed current spot is in a small circle, and when the contact time is long, further small holes are formed; the contact with the electrical plug causes paired damage; and The shape left by conductors such as screwdrivers and needles is the electro-branding or electrical imprint, which can often be used to infer electric shock tools. However, if the power is turned on for a long time, the original electrical imprint may become no longer obvious due to the expansion of the damage range~www.NovelMTL.com~ If the contact between the skin and the conductor is incomplete, or the conductor moves on the skin during the electric shock, the current will It is also difficult for the shape of the spot to match the shape of the conductor.

If the contact voltage is low, the environment is humid, sweating at high temperature, or barefoot or barefoot touches the ground or charged objects, or immersed in charged water, due to the small skin resistance, plus the large contact surface of the conductor and the short contact time, it will not form. Typical current spot, only simple skin burns, epidermal exfoliation and subcutaneous hemorrhage, subcutaneous tissue texture hardening and other changes, or even no changes.

Therefore, it must be pointed out that not all electrocution fatalities show significant body surface changes, and sometimes, despite confirmed electrocution deaths, there are no significant galvanic-damaging changes.

The damage principle of the electric baton is the dual effect of high-voltage electric shock force and the thermal effect produced by arc discharge. Due to the small current, it does not form alternating current current spots, nor can it cause human death, but it can sometimes be used as an incentive to induce the onset of potential diseases in the body. to death. After the electric baton touches the skin, the damage pattern corresponds to the contact area of ​​the electric baton, often in pairs, and the distance between the two points is the same as the distance between the contacts of the electric baton. In the early stage of exposure, the skin is ischemic and pale; if the exposure time exceeds 30 seconds, the epidermis is red and swollen, or even necrotic, and the subcutaneous blood vessels dilate, hyperemia, and exudate; if exposed for a long time, the damage will gradually increase, and eventually the skin may appear coke-like. The higher the voltage used by the electric baton, the more serious the skin damage. The contact of the electric baton is close to the skin, and the damage is relatively light; if the contact is kept at a certain distance from the skin, the discharge produces electric sparks, and the skin is severely burned. According to the experimental results of electric baton shocking healthy domestic dogs, electric baton cannot directly cause death, but repeated electric shocks in a short period of time can lead to high excitement and subsequent failure of animals, life dysfunction, and even life-threatening.
