At this time, Tian Zhen reported his examination results to Xing Lao very seriously and said: "Teacher, I found traces of apricot invasion, and I haven't found any obvious resistance injuries yet, but I don't know if I can extract DNA smoothly." I would try to find the killer's dander in the nails of the corpse. ”

Xing Lao nodded, pursed his lips a little angrily and said, "Luo Chuan, I hate these scum who bully the old and young women and children the most!" Such people are often very incompetent losers in society. They can only find their presence if they vent their strength from weaker people. It's up to you to catch him, I'll try to help you find the suspect's DNA. ”

Luo Chuan nodded and said, "Don't worry, I won't let this kind of pervasiveness do whatever I want." Actually, I already know the general situation of the suspect, but he ......"

"It's just that it's weird how he got up the tree, isn't it?" Xing Lao reacted quickly, and immediately knew what Luo Chuan was thinking.

Seeing that Luo Chuan acquiesced, the old man continued: "If you want to know how he got up the tree, you have to start from the tree!" Didn't you say that several truckloads of branches and trunks were brought back? Do your research and you'll find out. We ordinary people often say that people are watching the sky, but in fact, there is more than that! The sky is watching, the victims are watching, and all the grass and trees that witnessed the murder are watching. From them, you can get a lot of information to reconstruct the last scene of the murder. ”

As he spoke, Xing Lao took out the stomach that had just been dissected by the corpse and pointed it to Luo Chuan: "It doesn't seem complicated on my side, the deceased's poisoning came from the mouth." There are slightly broken ulcer-like spots in the mouth, grayish-white mucus in the stomach, and a little burger and wine. If there is no accident, she just ate food containing a large amount of sedative and forbidden drugs, so she became delirious and semi-comatose, giving the murderer a chance. ”

"Will it be a death from drug poisoning?" Luo Chuan asked.

The old man shook his head very affirmatively and said: "In fact, it is not easy to commit suicide by drinking sleeping pills, and the lethal dose of ordinary sedative drugs requires at least 100 tablets, but there have been many precedents that it is still good to eat more than 300 tablets." Not to mention that it was difficult for the murderer to buy hundreds of sedatives, it was an impossible task to say that he had 300 pills sandwiched in a hamburger without being discovered. If you want to make people unconscious instantly, it is not too easy unless it is a special industry such as medical care and police affairs. Ether, sevoflurane, propofol are not easy for ordinary people to get their hands on, and even if they find a way to get their hands on them, they may not be pure enough, and non-professional murderers should not choose this way. Let's talk about using bricks...... It's too violent, and if you don't handle it properly, your brain will burst, which is not conducive to cleaning up the scene. Therefore, tranquilizers with sip wine are the most convenient and worry-free. ”

“…… The killer made the victim eat food containing a small amount of tranquilizer and made the victim drink a little alcohol...... This is really not a person of taste. And what about the ultimate cause of death? Luo Chuan asked.

Xing Lao gestured with a scalpel and said, "A knife is fatal, penetrating the back of the heart." The murder weapon, like a relatively large awl, should be a special tool, not a must-have at home. ”

"Didn't you say two sharp wounds?"

"Yes, one knife is fatal, and after death, another knife is made." Xing Lao spread his hands as a matter of course.

"To vent anger at the corpse of the deceased is to kill excessively. Come on, you're busy! I'm going to study those poplars, and after all the autopsies are completed, you can definitely let Tian Zhen find me as soon as possible. Luo Chuan pleaded sincerely in a little anxious.

The old man waved his hand with his back to Luo Chuan, and began to continue to work on the autopsy. It was obvious that he didn't want to talk anymore and didn't want to be disturbed anymore.

Tian Zhen seriously assured Luo Chuan and said, "Team Luo, you can rest assured!" You and Professor Guan are also tired, let's rest first! As long as the results are out here, I will definitely rush over and tell you the results as soon as possible. You're tired, rest. ”

Luo Chuan believes in Tian Zhen very much, this girl does things differently from ordinary girls. The efficiency of the work can even surpass that of the gay men in the same class. So Luo Chuan didn't say more, thanked him and left the forensic office.

Those poplar branches have been piled up in the evidence room, according to Luo Chuan's meaning, let Guan Shan rest first, and then notify Guan Shan when he has news here. But Guan Shan disagreed, he couldn't help but reject Luo Chuan's suggestion and said: "Don't worry about me, I can still help if I can't keep it on those branches!" Since it was said that one case was solved, then one together. Otherwise, I'll go back to teaching the students. ”

Seeing this, Luo Chuan no longer insisted, and the two tacitly accelerated their pace and walked towards the evidence room.

When I came to the door of the evidence room, I found that the police officers were all standing outside, whispering dejectedly. Luo Chuan walked over and asked very puzzledly, "Why are you outside?" All the evidence inside has been investigated? ”

One of the police officers said with a bitter face and aggrieved: "Now even my desk is piled up with your trees, Team Luo...... You've given too much work this time, right? Even if we wanted to work right away, we wouldn't have anywhere to start! If you go in and take a look, you know that it is the evidence room, and if you don't know, you think this is a nursery! ”

Luo Chuan glared at the police officer who spoke, pushed the door and walked in. However, as soon as I came in, I found that maybe there was some truth in these police officers being "not doing their jobs" outside...... The house was full of poplar trunks, and there was hardly room to put your feet.

The police officer just now pulled his head outside the door and asked, "How is it, Team Luo, I didn't lie to you, right?" You see, it's not going to work......"

Luo Chuan turned around slowly and smiled coldly: "Why can't there be any way, it's very simple!" ”

The police officer was stunned: "Ah......?" Very simple? ”

Luo Chuan said expressionlessly: "Yes, isn't it over if you put all these things at the door in the aisle?" After inspecting a batch, replace a batch. Such a big police station, such a big place inside and outside, can't make this little space? ”

The police officer opened his mouth wide in surprise for a long time before squeezing out a sentence: "This ...... Team Luo...... Isn't that good? We're destroying the environment of the police station and affecting everyone's work......"

Luo Chuan replied without thinking: "It's just a little tree, what can affect their work?" Besides, human life is at stake, is the working environment important, or is the case important? Hurry up, don't be stunned! When someone asks about it, they say I made you do it! Tell them, whoever has an opinion, go directly to Luo Chuan! Now hurry up and test these poplars and sand and garbage for me to test clearly, find the evidence of the crime, and let's get off work together. ”

Luo Chuan said it easily, but the faces of several forensic police officers outside the door turned white. As we all know, Luo Chuan is the master who solves the case and does not take a leave of absence for two or three years. Leave work with him? I'm afraid it's going to be a long way off...... It's really unknown how long this class will last.

Thinking about these problems, the police officers did not dare to delay any longer. After all, you can finish work early before you can get off work early.

Guan Shan also brought gloves to help collect evidence, and at the same time did not forget to smile at Luo Chuan's domineering policy. It's no wonder that the second captain has always disliked Luo Chuan, and now it seems that there is a reason.
