"No, no, if you analyze this disgusting crime scene with the premise of a single person committing the crime...... If you only use one of the four items, you probably won't be able to finish it in one night. ”

"Huh?! I know! ”

Su Kuobei, who had been in a state of anxiety, suddenly interjected, she raised her right hand and shouted loudly like a primary school student who was eager to answer the question, "This guy must have used all four items!" ”

"That's right, that's probably how it should be." Lin Fengmian took out a lollipop from his pocket, handed it to Su Kuobei, whose eyes were shining, and then continued to analyze to everyone.

"According to my reasoning, the murderer should have used these four items separately to complete the whole scene; However, it is necessary to find out exactly which item caused the victim's death...... Then the dagger and the stone didn't run. ”

"Then you mean that Liu Zongwei first killed the victim with a stone, and then bleed him with a dagger to stain the tree?" Li Zhaozhen saw that there was candy to eat when he answered the question correctly, and immediately put on a look of eagerness to try, and without waiting for the leader next to him to ask, he rushed to answer first.

"That's not right." Lin Fengmian shook his head and corrected him, "It's just the opposite of what you said. ”

"On the contrary?" Hearing this, the people were stunned again, and the opposite meaning was to say......

"That's right, Liu Zongwei first killed the deceased with a dagger, and then used stones to create an illusion, oh yes-"

Glancing at Liu Zongwei, Lin Fengmian shrugged.

"Before you used a dagger to kill, you probably used the contents of that little glass bottle first, right?"

"The poison?" Liu Zongwei asked rhetorically.

"That's not right." Lin Fengmian shook his head.

"If tetrodotoxin is mixed with other things, it smells weird, and we can't identify it right away...... And because that thing isn't puffer fish poison at all, I want me to say that this bottle is supposed to be what you use to hold ethanol or something; You control the victim first, and then you do the bottle...... Isn't it really too much trouble? But it doesn't matter, it's this dagger that really killed the victim. ”

Putting on plastic gloves, Lin Fengmian used his index finger and thumb to pick up the bloodstained dagger in the cloth bag and shook it symbolically.

In fact, there is no need to wait for Liu Zongwei to make trouble, and other people around him will also ask questions first, such as ...... If it was a person who was killed with a dagger, why was there no knife on the deceased? Not to mention those places that are easy to kill, Li Zhaozhen and Hou Ange carefully examined the poor girl on the ground, and at this moment, there are almost no traces of damage from sharp daggers in the places on her body that can be observed with the naked eye.

In this case, why is it said that the murder weapon is a dagger?

"It's not hard." Lin Fengmian shook the knife in his hand very casually, carried it to the front and asked Zhang Chaoran and the others, "Have you found anything with this dagger...... Hmm, what's special? ”

Hearing Lin Fengmian say this, everyone gathered their eyes on the dagger again, but they looked at it for a long time...... No one saw any difference in this thing.

"KNOW THE STRIDER MANTRACK 1 BIG? This dagger is based on it. ”

Seeing that a bunch of law enforcement officers didn't know this thing, Lin Fengmian had no choice but to help his forehead and start forcibly popularizing science.

"BIG's prototype blade is 6.5 feet long and about 4/16 foot wide, and was originally designed by cutlery designer Mike Strider according to his own knife habits, and the prototype design was taken from MT; Judging from the traces, this one should have been altered by someone without permission, and the technique is not very professional, and the advantages of the piercing power and cutting force originally brought by the perfect spear-shaped tip have basically been damaged to varying degrees. ”

Lin Fengmian pointed while talking, and explained to Zhang Chaoran and others one by one.

"The original handle of this dagger was so long that if you had seen it, you would have felt out of proportion; However, the center of gravity is at the neck, so that the weight on both sides is very balanced, and the long handle allows the user to use it in any hand shape without discomfort...... In short, this dagger is perfect for people with larger hands or wearing gloves. ”

"And what is the purpose of the round object at the end of the handle? Is it to relieve the impact of the hand during the puncture? Or is it just ...... Ornament? ”

Xiao Du was born in the Military Academy, and he was quite fond of these cold weapons, and he was listening carefully when Lin Fengmian explained the dagger, and he even raised his own questions.

Lin Fengmian smiled and shook his head at Xiao Du, he turned the sharp weapon in his hand and presented the round handle part of the tail in front of everyone.

"This dagger has traces of poor modification in many places, but I'm guessing you've found it too...... Isn't the round handle of the tail wrong no matter how you look at it? ”

After he mentioned it a little, everyone present nodded their heads - especially Xiao Du, when he saw this dagger, he had the feeling of "always feeling that this thing is weird", and now he can be regarded as finding the reason.

"That's right, an absolute weapon that breaks the wind and water, whether it is on the premise of considering the beautiful appearance, or considering the practical range of precision and high speed, the round handle of the tail is extremely unreasonable."

Putting the dagger in his hand and checking it, Lin Fengmian reached out again and took out the stone in the cloth bag.

"Look at it."

As soon as the words fell, he put the stone on the tail of the round handle of the dagger and compared it, and everyone present immediately exclaimed.

"Hara, so that's it!"

"That's right."

Smiling slightly, Lin Fengmian put down his things and took off his gloves, then clapped his hands and explained, "This incompatible tail handle was added by the prisoner himself, it not only destroyed the unique beauty of the cold weapon, but even the speed and power of it were greatly reduced-but even so, the prisoner still chose to do this...... Why? ”

Speaking of this, Lin Fengmian turned his head, stared at Liu Zongwei coldly, and said word by word, "Because you need it, you need this round tail handle that is both ugly and ridiculous, clumsy and pathetic, and you need to use it - to hit the victim's head!" ”

"But...... But didn't you just say that he killed the victim with a dagger and a stone? What about the stones? ”

Zhang Chaoran was stunned while holding the blood cloth bag, they never thought that this Liu Zongwei could be so cumbersome in order to kill someone, it was simply ......

However, Zhang Chaoran remembered that Lin Fengmian had said before that Liu Zongwei used daggers and stones to kill victims, since he used the impact caused by the handle of the dagger, where is the role of the stone?

"The role of the stone is only to mislead."

Shrugging his shoulders, Lin Fengmian explained.

"As you saw just now, one side of the stone is about the size of the round handle at the end of the dagger. In this way, the whole process of the crime is clear and clear - the murderer first controls the deceased, then repeatedly hits the deceased on the head with the handle of the dagger, knocks him alive, and then repeatedly strikes the impact wound with the side similar to the stone. ”

So, no matter how we look at it, we feel like the wound was smashed out of a stone...... Such? ”

"Ah, that's it, the wound on the deceased's head was indeed made of a stone, yes, it's just that it was the dagger handle that killed her."

After reasoning, Lin Fengmian turned his head and glanced at Liu Zongwei; The latter still doesn't seem to give up, and still aggressively asks where the evidence is, why is it the handle of a dagger or something.

"These tricks can only confuse and confuse the people on the scene, and as for the evidence, your provocation is one of them; Second, there is nothing to say about taking these exhibits back to the appraisal department for examination. I don't know what you're working so hard for, but now that you've uncovered the mystery...... Then answer my questions honestly as agreed. ”

The grim smile on Liu Zongwei's face did not change, and at the same time, he said this to Lin Fengmian with a sneer.

"My mission...... It's done too. ”
