After cleaning, the scene must have wanted to cover up some traces, Du Heng immediately asked Zheng Qian to do a luminol light experiment, and as soon as the light was turned off, several people were shocked, and the place that spread outward from the head of the bed was all blue-blue reaction, which proved that a large amount of blood had appeared in this piece.

"It seems that neither of these two has anything to do with this case...... Ding Qi said.

"Issued a notice of assistance in the investigation, and the whole city searched for this Yuan Rui ......"

When they returned to the detachment, Wang Yue came out of the forensic office: "It has been determined that the poison was poisoned, and the poison was a poisonous rat ......."

"It's impossible, it's not that rat poison was banned as early as 91 years ago, and the manufacture and use of it were stopped. Zheng Qian was really surprised when she heard about this medicine for the first time.

"We have also compared the poisons, and have confirmed that the deceased is about 10mg of rat poison inside, this drug is extremely difficult to degrade, for adults, the lethal amount of rat poison is 5-12mg, and it will be poisoned within about ten minutes to half an hour after oral administration, and when the poison occurs, there will be tonic and paroxysmal convulsions, and finally form an angular arch reflex, which is the first strange posture we see him. Wang Yue explained.

"The key is how did this poisonous rat come about, it is forbidden to sell it on the market, could it be that the murderer made a homemade poison?" Zheng Qian asked.

"I probably know ......" Yang Lei walked forward with the computer: "I compared this Yuan Rui with the information in the information database, and came to the conclusion that he was originally from the same school as Yuan Chu's real name was Qian Ying." Qian Di is the physical education teacher of that school, and he was expelled for being suspected of molesting his classmates many times during his school years, and he was also expelled from this Yuan Rui, and the two of them often collaborated to molest girls. Later, they came here, thinking that they were really dedicated to the Buddha, but they didn't expect that they were hiding dirt. This Yuan Rui's family used to make a fortune by buying pesticides and rat poison, and later opened a small supermarket, but his parents went to travel and encountered a tsunami when he was in the first year of junior high school, and then he was raised by this Qian Zhen, who was his uncle......

"As I expected, this Yuan Rui should have been noticed by him when we went yesterday, and then decided to strike first, make Yuan Chu's murder a scene of suicide in fear of crime, and then clean up his house, thinking that he could escape in this way, it is simply foolish. Du Heng said.

"Now I'll help you report it, and there will be news soon. Mai Dong patted him on the shoulder.

"Let's rest tonight, it's going to be harder to wait for someone to catch it. Du Heng said and asked everyone to go back and rest. After a busy day, he ate a bread for dinner, and when he got home, Mai Dong's stomach was growling with hunger. Fortunately, there were dumplings left by my mother in the refrigerator, and the two cooked more than ten of them, and they fell asleep after a full meal.

As soon as Mai Dong's alarm clock rang in the early morning, Du Heng's mobile phone next to him rang, the two colleagues opened their eyes, Mai Dong turned off the alarm clock, Du Heng reached out to pick up the phone, and the voice on the other end of the phone was quite excited: "Team Du...... Yuan Chu caught it!"

When the prisoner was caught, he heard such good news as soon as he opened his eyes, and the two looked at each other with great joy in their eyes.

Du Heng walked in, and Ding Qi just came out of the interrogation room: "This kid is very fine, he planted everything on Qian Yin, saying that Qian Bin did everything, he just helped carry the corpse." Now I probably know that there is no proof of death, and my tone is very tight, and he is also a ruthless character. ”

Wang Yue came out of the forensic office: "No matter how hard he is, it won't help, we found sperm spots on a female corpse, and it was confirmed by comparison that it was not Yuan Chu's, but his. ”

"I'll meet him when I go in. Du Heng went into the interrogation room, Mai Dong watched outside, this person was actually very calm, and it was also magical.

"Do you call you Yuan Rui or call you Wang Rui?" Du Heng flipped through the information in his hand.

"Whatever, it's just a name, comrade policeman, I was really wronged, these things were done by my uncle, he raised me, and I can't be ungrateful, so I helped dispose of the body. Yuan Rui said: "I admit to harboring criminals, so you can say that you will be sentenced to a few years." ”

"That's not all. Du Heng said: "We found a lot of blood stains in your room, and we also found your sperm ......spots on a woman's corpse," Du Heng handed him the test results: "These two alone can completely determine that you and Qian Ying are murdering people." ”

"Impossible...... I'm ...... You are framing me!" Wang Rui was anxious.

"Young people still have to read more, you see that your words expose that you are uneducated. I don't think you know about the luminol glow reaction, I'm going to teach you a lesson today, the luminol glow reaction is designed to identify blood stains that have been scrubbed repeatedly and for a long time, and this detection method is very sensitive, and the content of one millionth of blood can also be detected. Have you ever heard a sentence, Skynet is magnificent, negligent but not leaky. As long as you do something, no matter how much you try to hide it, it will always be there, and it will be turned out one day. Du Heng looked at him calmly.

"I don't believe it...... I don't believe it!" Wang Rui still refused to believe the fact that he had been exposed.

"Then let me tell you how the whole thing happened. You and your uncle Qian Ying came to this temple three years ago, and the temple often has single female pilgrims, and you can use the free Q&A to lure them to the side hall, and Qian Di will either attack them on the spot or wait until night to do so. I've checked, the lighting in the side hall and your dormitory is extremely bad, the dark environment, on the one hand, the girl chooses to swallow her anger for safety, on the other hand, she really can't find your clear characteristics, of course, there are also strong temperaments, so you choose to do it. Since the road in front of you has been cleared, the path behind the mountain has gradually become uninhabited, which makes it more convenient for you to dump the corpse. Yesterday you must have found us walking towards the back mountain, you hid behind and secretly followed, when you found out that we saw the corpse, you were frightened, what scared you even more was that you found out that we were the police, now you are even more panicked, what can you think of, the only thing you think of is to find someone to be a substitute for the dead. You know Qian Di's daily habits very well, so you think that as long as Qian Di dies without proof, plus the evidence in his house, you can escape. You see you've calculated it, and you've worked so hard to prepare, what's the use, before you commit a crime, you should have thought that there would be such an end. Du Heng said that he couldn't help but feel a little regretful, this person was just an adult, and now his whole life has been ruined.

"What do you know, and what qualifications do you have to say about me?" Wang Rui suddenly became excited, he looked at the watch that Du Heng was carrying: "I also bought this watch three years ago, but it never belonged to me!" Wang Rui said and sat down: "You must not have lived such a day, you can't eat enough every day, you only have one piece of clothing in winter, and you have to tell your classmates that this is a kind of exercise." You see that all the people have their parents to pick them up, but all you have is a beating when you go home. You think those girls are pitiful, but what about me, if I don't do those things, he can kill me, what can I do?" Wang Rui said and looked at Du Heng: "Do you want to tell me, what kind of is to call the police." ”

Du Heng looked at him and didn't speak.

"What's the use? I haven't done it, but in the end......" He also tried to call the police, with a body of injury, went to the police station and sat in the cold office waiting, what was the last thing to wait, the man explained: "This child has always been disobedient, his parents died, I am worried that the teaching will not be good, and it is inevitable that he will be more strict on weekdays." So......" The man expertly handed over the cigarette, and finally the policeman took the cigarette and pushed him back to be obedient.

"You definitely haven't had that experience, you feel so much pain that you want to stop breathing, but you still can't die, you feel like you're going to die again and again, and then day after day you wake up again. Wang Rui became more and more calm: "Later, I found out that as long as I follow him, as long as I am obedient, as long as I live like a dog, that life will be much better." Do you know the first girl, I still remember her name, Ma Fangfang, she was only thirteen years old, I was sick 'again' that day, she sent me homework, you say how good people are, God will never favor good people. The man came back, and he was drunk again. I still remember Ma Fangfang begging me, first crying, then whispering again and again, and she asked me to save her...... But do I dare? I don't dare, I'm afraid, as soon as I stand up, I will remember what it feels like to be beaten, I can't help it!" Wang Rui said with tears in his eyes: "If there is the first one, there will be a second ...... There will be an infinite number of them, and I'm in hell anyway, so why let the rest of us live well, or we all die together......"

Du Heng felt that his expression was wrong, and stood up, but Wang Rui put his hand into his mouth, biting his fingers and laughing, Du Heng hurriedly rang the bell: "Quick! Call the doctor." Then he began to induce vomiting on Wang Rui, but Wang Rui gritted his teeth, but after a few minutes he began to convulse and foam, and when the ambulance came, he stopped breathing, and there was a hint of a smile on his lips.

The closing report of the case was written by Ding Qi, Du Heng was temporarily suspended, and the death of the prisoner during the interrogation was not a trivial matter, fortunately, there was monitoring, and Du Heng did not violate the rules for half a day when he interrogated on the same day, but he had to investigate in accordance with the rules. Mai Dong was very happy about this: "You have been busy with the case for many days without resting, and now you finally have a chance to have fun for a few days, isn't it relaxing?"

Du Heng was originally very depressed, but he couldn't cry or laugh when he saw Mai Dong looking like he had picked up a big bargain: "If you are suspended, you will have no salary, and we will probably drink the northwest wind this month." ”

Mai Dong touched his face: "For the sake of seeing you chic and handsome, my sister has wrapped up you, given you money to spend, given you food, and bought you clothes...... Du Heng's face is so smooth, touch it two more.

Du Heng's eyes were dark: "Then what does my sister want me to do?"

"Cooking, laundry, mopping ......" won't work.

"That's not good, I don't sell my body, I don't sell my art. Du Heng didn't agree.

"Be a good law-abiding citizen and never do anything that violates the law and discipline. "Mai Donning is unyielding.

The two laughed, and the meaning of home is about to be able to draw strength to set sail again when you are tired.
