The crime rate in Japan is very low, but the number of missing people is about 85,000 each year.
This is official statistics. Judging from the work ability and efficiency of the Japanese police, the actual number of missing people should be far more than it is, but it is difficult to determine how many people have disappeared.
Two missing persons were killed today, one in the morning and one in the afternoon.
No one fell asleep tonight. The whole building was brightly lit, and police cars kept flashing in and out in red and blue. The search headquarters has been established, and all the elite soldiers and generals from the Hirano search class have been gathered.
Before being scolded as a pig's head, he pulled out the prisoner.
This is different from previous cases. Explosion cases or serial bombs are easy to be on national news, and the nature of killing one or two people is hugely different from ordinary homicide cases.
Nakano Eri is now a "strong general" of the Hirano Police Station. She has three groups of people under her command and was assigned tasks at the search headquarters meeting. She immediately invited the "elite soldier" Qihara Take to help analyze.
For case matters, try to obtain additional insurance.
The safety of staying in the police station is still guaranteed. I think the prisoner is not so crazy that he dares to come to bomb the police station. In addition, there is a consultant fee, so I was very happy to cooperate with Nakano Erika before, so Takeshi Nihara brought Kiyomiya Liuri over.
Make a fuss and just go over the case information to see if you can provide some advice for arresting criminals.
The first incident occurred at 9:32 this morning. A man suddenly rushed out of an alley from a bustling commercial street outside the city center. He was tied to a simple bomb behind him and cried and shouted "Help"
, "Help me", "Please, please cut the blue line for me", etc., holding a pair of scissors, looking for people to help dismantle the bombs, but only scaring the people around me to escape everywhere, and the scene was not dismantled
Issue experts, no one dares or is willing to help.
About five minutes later, there was a huge muffled sound. In the public eye, the man was in a desperate howl, his back exploded, and he flew out, bloody and died on the spot, which affected several people around him, causing three people to
Slight injuries, minor burns in many people's respiratory tract, and causing greater panic and fleeing, causing dozens of people to break their heads, scratch their knees, and twist their ankles.
"The explosives turned out to be ammonium nitrate glycerol. I said why the sound was so strange." Qi Yuanwu looked at the information and thought about the scene at that time, but he solved a little doubt before.
The first case happened early, and the forensic class had completed the on-site investigation and search. It was too miserable to discuss the body of the victim, but the fragments of the simple bomb were found, which probably restored the appearance of the bomb. The explosives
The test was also completed, and it was rare to have higher efficiency once.
"What is ammonium nitrate glycerin?" Qingjian Liuli was watching the police officers in the big office coming and going, showing an elite style, and her beautiful big eyes were full of envy. She wanted to join in and work together. She heard seven times
Yuan Wu came to his senses when he spoke, and he also wrote down the key points of knowledge - when the ammonium nitrate glycerin exploded, it sounded like a super bullshit fart from a distance.
Qi Yuanwu was also interested in this matter, so he went to the forensic class to take a closer look at the photos of the bomb fragments found from the first crime scene, and explained casually: "A explosive that is easy to synthesize and can release toxic gases."
.The disadvantage is that it is relatively small in power and is more dangerous when synthesised by hand. It is easy to kill yourself first, but the advantage is that it is difficult to track the source."
Qing found that Liuli didn't understand and could not understand the string of chemical nouns on the information, and said curiously: "Why is it difficult to track the source?"
"Because all materials can be obtained legally, the main material is fat pork. Even if you buy 100 kilograms at one time, no one will suspect that you want to blow someone else to death, and it is even more impossible to record it."
"Can fat pork be fried to death?" Qingjian Liuli was stunned for a moment, remembering the re-cooked pork. It was the most delicious fat pork she thought, but she never expected that such delicious food could become a weapon.
"Of course, everything in this world can be a weapon. Just refining fat pork oil and adding caustic soda can get soap and glycerin, and then nitric acid and sulfuric acid are in a ratio of 3:3:4..." Qi Yuanwu said halfway through his mouth
Stop talking, "Forget it, I won't tell you in detail, so as not to turn around and blow yourself to death, but all the materials needed for this explosive can be separated or synthesized by home daily necessities by yourself, and you can easily avoid control
.”
After a pause, he added, "If you really can't figure it out, you can understand this explosive formula as Nobel's 'Dinamai formula' back then. Nobel is said to only go to elementary school and has no sense of science.
, it is because of not being afraid of death, and dares to mix nitrifying glycerin with all kinds of things, and finally get rich. The same is true for prisoners today, using an outdated low-power explosive that can be mixed with hand-made materials using civilized methods.
”
Qingjian Liuli actually didn't understand it very much. She didn't know what the Denamai formula was, but in order not to seem too ignorant, she suddenly realized: "So that's it..."
It is difficult to track the explosives, so it seems that they can only find clues from the victims, but she found that Qi Yuanwu was still looking at the fragments of the bomb, and couldn't help but say strangely: "Can clues be found on these fragments?"
Qiyuanwu shook his head: "No, it's all rough handmade products, from the support rod, the fixing bolt to the plug, the medicine pool, the igniter, it looks all homemade, with obvious signs of hand polishing, but combined with the explosives
, can already explain a problem."
“What’s the problem?”
Takeshi Nihara smiled and said, "The prisoner is very likely to be self-taught, or used old-fashioned teaching materials. He is a little crazy and is not afraid of death at all. The production is so rough that he is very likely to blow himself to death or blow up before committing the crime.
Go to the hospital.”
Qingjian Liuli looked at him speechlessly. After a long time of analysis, he found a big fuck. The prisoners were blowing around the city center. Do you think he was in a normal state, so is that possible?
She was speechless for a moment, looked at the recovered bomb picture, and asked strangely: "Okay, we'll be crazy to be a prisoner first, but he also loaded a timer for the bomb and gave it to the victim.
A pair of scissors asked him to go and ask someone to help cut the wire... What is he trying to do? Is there anyone who can help cut the wire? Can the bomb really be removed?"
Shi Yuanwu also looked at the recovery picture about the bomb timer and nodded slightly and said, "Theoretically, if you can cut it right, it will indeed make the bomb invalid. As for what he is looking for..."
Kiyomi Liuri was excited and solved a puzzle that had been puzzled for a long time. He asked excitedly: "Can you really stop? I thought it was made up in movies and TV series."
"Art comes from life, and that part has been adapted, but it is indeed not made up." Qi Yuanwu pointed to the recovery picture of the time bomb and said, "In the simplified way, the timer is a parallel circuit with two branches.
The detonator is placed on one of the branches, and the other branch is a simple wire.
The science textbook explains that if in the parallel structure, one of the two branches has a resistor, that is, the timing detonator, and the other branch has no resistance, the current will all go from the unresisting branch, and the fire generator will not get it.
The current cannot work, and the bomb cannot detonate at this time. It can only wait for the timing to arrive. The mechanical or electronic structure of the detonator takes effect, causing the resistance to disappear and the current flows into this branch to stimulate the igniter. The igniter ignites the medicine pool and causes
A series of explosive reactions.
So if you cut the line, it can theoretically prevent the bomb from detonating.”
Qing Jian Liuli understood and felt that it was not difficult to dismantle the bomb. She immediately said excitedly: "It's that simple? Then can I cut off all the wires? Or just pick out the battery, so that the timer will run out of power.
It won't detonate either!"
Qiyuanwu looked at her and couldn't help but smile and said, "You are such a genius. If the prisoner did not install a set of capacitance circuits to detect voltage, it would be feasible, but the bigger thing is that the prisoner must have installed it and the voltage is instable.
In an instant, you were immediately bombed into the sky.”
Oh, by the way, this guy is talking about the simplified situation. The prisoner must not be that stupid. He will definitely install some other things in a mess. He even designed several sets of current loops to prevent others from cutting wires randomly and smashing and dismantling the timer.
Then, take the bomb out of the human body or just pick up the battery.
But then again, no wonder high school goes beyond the scope of compulsory education, and can be considered higher education. It turns out that as long as you graduate from high school, it is enough to go out and commit a crime!
The things that high school students learn are a bit amazing. If you are not afraid of death, you can make your own time bomb after learning well.
Qingjian Liuli completely understood, gave up the idea of changing jobs as a bomb disposal expert, and prepared to go back and continue to strengthen self-tutoring. You must learn high school knowledge well, otherwise you will be despised even if you are a criminal.
.
She quickly changed the subject and looked at the colorful wire photos and said, "If the bomb really could stop working by cutting the wire, the prisoner gave the victim a scissors and asked him to ask for help. This was what he did. He also deliberately for this.
I used wires of different colors... No, the time bombs in the movie seem to be colorful, why is that?"
"There is no problem with this, because everyone knows that bombs are super dangerous goods, and it is impossible to assemble them in your home or carry them with you every day. That is not a crime, it is a desire to commit suicide, so it is just a temporary assembly when it is used.
If the wire is not divided into lustfulness, the prisoner will use the power supply, the firearm, the spare firearm, the powder chamber, the failed firearm, the trigger and the timer will be connected together, and the wrong wire may be mixed and connected during assembly.
He killed himself."
Qiyuanwu touched his chin and said, "But why the prisoner allowed the victim to ask for help? He even gave him tools. It was really weird. It should have some purpose, but it is difficult to judge what the purpose is for a while."
A black shadow flashed through Qingjian Liuli's mind and said vigilantly: "Is it a mysterious person? He came out to commit crimes again to have fun?"
"Who is the mysterious man X?" Takeshi Qiyuan looked at her in surprise, "Which stupid code name is the character in which junk novel?"
Qingjian Liuli then remembered that the code name was found by herself. She had not told Qi Yuanwu yet, and hurriedly said: "It was the accomplice of the last suicide insurance fraud case. He also sent you something. You didn't say he was a perverted entertainment.
Did you commit it? Could it be that he tied a bomb to the victim this time and wanted to see the victim struggle to have fun?"
"Is he?" Qiyuan Wu also had a deep impression of this person, but he touched his chin and thought for a while, pondering, "Probably not. Last time he induced and assisted others in committing crimes, and personally took action to tie people and bombs... and last time
The characteristics shown are not very consistent and the suspicion is not high."
Qingjian Liuli also touched her chin and thought about it, and felt it made sense. The mysterious person X gave her a feeling of being arrogant and manipulating the fate of others. She went straight to commit the crime and suddenly she got off... Thinking about it this way, it was really not suspicious.
big.
She hurriedly went to find the victim's information and said, "Then let's take a look at the victim's situation. Although it may be a randomly selected victim, the prisoners kidnapped the victim, at least some clues can be left behind.
, you can find clues from here.”
She is very enthusiastic, more enthusiastic than the detectives. She is very active in solving the case, and at least she wants to make contributions. But before she finished speaking, the detectives in the large office suddenly became turbulent. Someone covered the phone and shouted excitedly: "Xiaoli
There was news from the police department, and the prisoner called to make a request!”
