"The ingredients of this colloidal bomb are ******** and explosive gum (the colloids formed by the dissolution of nitrocellulose in ********) as raw materials. The addition of absorbents and other explosives www.biquge.info pen ~ fun ~ pavilion was developed during the Second World War, and it ******** a type of explosive, mainly made of nitroglycerin and absorbents. This kind of explosives have good explosive performance, high detonation sensitivity and good detonation performance, but due to poor production safety and high cost, the production volume is not large, and the market share of explosives is small, and almost all of them are made into specifications of small diameter below 50mm, which are used for underground blasting and underwater blasting in coal mines. According to the different absorbents used, they are mainly divided into ammonium nitrate colloidal explosives (ordinary colloidal explosives) and sodium nitrate colloidal explosives and semi-colloidal explosives (refractory colloidal explosives). Yang Yat-sen is like an encyclopedia, and a series of words keep popping up, which makes people overwhelmed, Zhou Lingwu listened to Yang Yat-sen's explanation and was even more impressed by Yang Zhongshan, it seems that not everyone in the Academy of Sciences can enter.

"I'm talking about industrial explosives, which are all legally permissible." Yang Zhongshan added.

"If that is the case, then we just need to pinpoint the murderer to the person who made the explosion?" The junior group said without thinking.

"No, no, I can't think like that. Although the colloidal explosives mentioned by Yang Zhongshan are commonly used in industry, the realgar explosives found in Li Yu's house are not. I'm sure the killer must be a skilled explosive maker, and the first suspect is a talent in chemistry, and most likely someone from your police force! Director Chu, let's see if there are any clues? Zhou Lingwu immediately stopped Director Chu as soon as he put forward his inference, he is now very suspicious of what this Director Chu relied on to become the director, how can such a simple question be confused?

Director Chu now has complete trust in Zhou Lingwu, after all, he has investigated so many scenes together, and almost every scene is watching Zhou Lingwu alone, how can this not make people inertia?

After thinking about it, Director Chu could only determine one person, and that was the police officer surnamed Wang, who had died, and was one of the victims in this accident.

Among all the police forces, he is the only one who graduated from chemistry, but it doesn't make sense to say so, Wang is now dead, and there are no bones.

“！” As if he had suddenly thought of something, Zhou Lingwu widened his eyes and asked a police officer at the scene, "Who was the first to enter the scene?" ”

Director Chu didn't know what kind of medicine was sold in Zhou Lingwu's gourd, but he knew that Zhou Lingwu couldn't ask for no reason, so Director Chu also hurriedly asked: "You all think about it, it's a big deal!" ”

"Report!" A small police officer said.

"Say!" Director Chu was anxious, and he couldn't help but speak in a louder voice and ordered.

"Yes...... I was the first to come in, please ...... Any questions? The little police officer saw Director Chu yelling at himself, and secretly said in his heart that it was not good, so he had to say it stubbornly.

Hearing this, Zhou Lingwu hurriedly stepped forward and grabbed the officer's shoulder and asked, "From the time you entered this room until the forensic doctor removed the body from the scene, have you seen Officer Wang's body during this time?" Even if it's a broken corpse? ”

The little police officer was dizzy by Zhou Lingwu's shaking, he broke free of Zhou Lingwu's hands to cover his head, and said angrily: "No, I didn't see anything, I knew that it was full of black smoke after entering the house, and the people in the team said that such a big fire king officer designated it was gone." ”

"Oops! You bunch of shit! One pass ten, ten pass a hundred, and you will pass on the truth to me! It means that the body of Lao Wang has not been found until now! When Director Chu heard this, he immediately blew up, and without conclusive evidence, he passed it from one mouth to another, and when he reached his ears, it became the truth! Can such a thing be spread falsely? At that time, if the case cannot be solved and Officer Wang is still missing, then according to Lao Wang's death, whose responsibility is it?

"Chu Bureau, don't worry, we found this." The little police officer was really scared of being scolded by Director Chu, and as soon as Director Chu changed his face, he immediately took out a transparent plastic bag containing the objects at the scene from the backpack he was carrying. Everyone frowned and looked over, they stared at this black thing for a long time and didn't see why, and then asked, "What is this?" ”

"Chu Bureau, this is the mobile phone of Team Wang. If we don't have this thing, can we just talk nonsense? Who's responsible? ”

Since Officer Wang's mobile phone was found at the scene, it proves that Lao Wang was at home at the time of the explosion, even if he can't find Officer Wang's body now, even if Lao Wang is unlucky.

"No, no matter how big the fire is, no matter how strong the impact of the explosion is, there will be no scum left, and Officer Wang's mobile phone was found at the scene, which cannot be used as strong evidence that Officer Wang has died, I think that the murderer is Officer Wang, and the person who imitated the Zodiac serial murder case is Officer Wang!" Zhou Lingwu said categorically.

I am afraid that this is the most confident time since Zhou Lingwu personally came forward to investigate the case, and he has never firmly determined that a person is a murderer before the evidence is conclusive.

Director Chu shook his head when he heard this, and wanted to deny it, but before he could speak, a small police officer who was busy said, "Impossible! Officer Wang is not that kind of person! ”

Zhou Lingwu followed the prestige, and the person who spoke was none other than the policeman who stopped him when he first came to the police station, Li Yu ordered to stop him!

Zhou Lingwu didn't want to waste time arguing with him, so he ignored the little police officer and continued to explain: "I think that the murderer is Officer Wang is justified, not conjecture!" ”

Director Chu didn't refute when he heard this, he motioned for Zhou Lingwu to continue, but the police officer who refuted it just now wanted to say something, but he saw that Director Chu had already agreed, so he didn't want to say anything.

After Zhou Lingwu got the permission of Director Chu, he continued: "I think he is a murderer for a reason. First of all, there are very few people who can know the password of Li Yu's safe, and there are only a few, these people are Li Yu himself, Officer Wang and Li Yu's wife. Li Yudi's wife has died, and Li Yu is now seriously injured and lying in the hospital's intensive care unit. Both of them had ready-made people in the morgue or in the hospital, but Officer Wang was the only one who used a burned cell phone to indicate his situation. ”

"Secondly, when I contacted Officer Wang in the flower shop before, he held a grudge because of his sister's death, and I thought that it was very likely that Officer Wang wanted to kill and take revenge. Who can be unsuspected? Only the dead! So Officer Wang made a desperate bet and wanted to cover up his figure by faking his death. But he was worried that Li Yu had been with him for too long, and he knew his little habits very well, so for the sake of insurance, he didn't even let go of his long-time friend, and killed the killer as well! ”

Zhou Lingwu said.

But Director Chu quickly asked, "How do you know that Lao Wang knows Lao Li's safe password?" ”

"These are my inferences, and when Li Yu wakes up, everything will naturally be known." Zhou Lingwu said.

As soon as the police officers heard that the wonderful inferences that Fang had just said were Zhou Lingwu's wishful thinking, and they were his own guesses, everyone disdainfully "cut", if you want to slander our respected Officer Wang just by relying on one of your "I guess", then I still advise you to come back as soon as possible!

Zhou Lingwu shrugged his shoulders noncommittally when he heard this, no matter what you say, I can't live if your Director Chu leaves me anyway, I can't solve this case if it's gone, and I'll leave if I get in a hurry, see how you beg me to come back at that time. However, this kind of small market mentality Zhou Lingwu only existed for a moment, and in a flash, he soon returned to the original indifferent temperament of no desire and no desire.

Director Chu was a little embarrassed and then teased: "Oops, why can't you stand the joke so much, isn't it just a joke, little brother, what's the matter~"

"The dead are great!" The police officer who refuted Zhou Lingwu said indignantly.

"You!" Director Chu saw that there were still people who didn't know how to lift and didn't have the eyesight to see the top wind, he couldn't help but sink his face and said, "Boy, are you stupid?" ”

"Hey~ Director Chu, don't say such things, I can understand his feelings, but if the matter is what I said, we can wait and see." Zhou Lingwu said with a stitch.

When Director Chu heard this, he pointed at the police officer who was shouting just now, and then turned his head and left.

This time, the clues found in the house of Li Yu and the police officer surnamed Wang were very impressive, Zhou Lingwu originally thought that he would not get any clues, but he didn't expect that even the final suspect in the case (at least Zhou Lingwu thinks so) has been determined after this trip. (To be continued.) )
