These little gangsters, after following the gang, have their own things to do, and when they go back to the village, they usually go back separately, and they usually don't go back collectively. But this time, Luo Feng actually brought all of them back in the village. I grabbed the head of one of the thugs, and I said in a cold voice: "Don't let me ask you to say another word, why did you go back to the village that day, tell me all clearly!" ”

My threats worked, and the ensuing inquiries went very smoothly. They told me that today, they all received news that an old man in the village had died, so they all rushed back to see it. This group of gangsters is fierce to outsiders, but they take good care of the people in their own village.

However, when they arrived in the village, they didn't see the dead old man, so they were stopped and questioned by Luo Feng's men, and finally brought back. I asked Luo Feng if anyone in the village had died today, and Luo Feng's subordinates replied that they had not seen anyone die in the village. I instantly understood that these little thugs had been deliberately led back to the village.

This group of gangsters wanders around all day long, and they can't tell where Lao Jiu was on the day he disappeared, which is very normal, but at the same time, they will be very suspicious. Luo Feng scolded again: "You mean, someone deliberately let us catch them?" ”

I nodded, and asked the gangsters who had given them the news, and they all said that it was Daxi who told them.

", I knew I wouldn't let Daxi go just now!" Luo Feng took a sip.

"Don't worry, you go investigate first, who Daxi has met with in the past two days, maybe you can find out." I said to Luo Feng.

Luo Feng called a few people and sent them out. I glanced at the gangsters, they did have some suspicions, and they were also locals of the village, but after learning that they had returned to the village after receiving the news, I felt that someone was interfering with our investigation again.

Luo Feng locked them all up temporarily, and when he and Luo Feng came out of the amusement hall, it was already evening.

Three days, half a day has passed like this, Luo Feng asked me if I was sure, I thought about it, and replied, since the words have been released, it must be done. Luo Feng asked me where I was going next, and I said I wanted to go to Feiji's house to have a look. After Feiji's death, I didn't observe the crime scene very carefully, and then I wanted to go, but strange things happened frequently, and I didn't do it.

Luo Feng drove the car to the economic villa area where Feiji lived, and after entering the villa area, Luo Feng and I both climbed over the iron gate outside Feiji's house and jumped in. It has been a few days since Feiji died, and with Chen Fan's guidance before, the police investigated very carefully, but unfortunately, they found no traces.

Luo Feng and I are going to go to Feiji's house to take a look, the door has been locked, we can only go to the back door, break the glass of Feiji's house, and then find a way to get in. The case has not been solved yet, so the crime scene has not been cleared, and we arrived at Feiji's bedroom, where there was still a lot of blood on the bed.

After going around and finding nothing, we went to the backyard of Feiji's villa, which was the first scene of Feiji's murder. On that day, some of the overthrown weeds have now returned to their upright state, and that is the place where I speculate that Fatty Ji was killed and fell.

On that day, I made a clear note of the location, and I walked to that one and began to think carefully.

"Fang Han, according to what you said, Fei Ji didn't even struggle, and just fell to the ground and died?" Luo Feng asked me.

I nodded my head to confirm that on that day, there was only one place in the grass that was toppled over, and based on the shape of the dumping, I presumed that it was overwhelmed by the fat base after it fell to the ground. However, other than that, the other weeds, most of which remain upright. Luo Feng also felt a little incredible, he said, although Fei Ji was frightened that day, and he was fat, he was a policeman no matter how he said it, and it was impossible for someone to hold a dagger and cut Fei Ji's throat directly in front of him or behind him.

"No matter what, let's fight." Luo Feng said.

There are very few blood stains on the grass, you only need to use an absorbent mat to pad it in advance, there are no traces in the house, you just need to be careful when the murderer transfers the body, and it is time to clean up the scene, Fei Ji's mouth is stuffed with dark paper, in fact, it is not weird. The case of Fei Ji's throat being cut is actually the most bizarre: why did Fei Ji die without struggling.

In other words, the question is how the fat base died.

Luo Feng's words reminded me. Indeed, if someone is holding a dagger and quietly approaching Feiji, Feiji will definitely find out, in this way, as a policeman, Feiji will definitely fight to the death with the murderer, and if there is a fight, it is bound to trample on more weeds and leave traces.

There are too many weeds in Feiji's backyard, and it stands to reason that a person will not come here at night. However, Fei Ji died here. It is likely that Fei Ji heard something and was led here, but if this is the case, Fei Ji must have been more vigilant at that time, and it is even more impossible for the murderer to kill with a knife.

I narrowed my eyes and asked Luo Feng, "What if, the one who is close to the fat base, is just a knife, and there is no one at all?" ”

Luo Feng was startled, he looked around and asked me: "No one, how could the knife get close to Feiji and kill him." Don't tell me, there are people who are so good at kung fu that they can throw a knife and cut people's throats so precisely. ”

I just smiled slightly, said no more, and stood in the position where the fat base fell. I carefully recalled the direction in which the weeds had dumped that day, and soon I had a rough guess of the position in which he was lying when he fell: he was lying on his side. I looked around, and the backyard was still relatively empty, with nothing but a tree and weeds all over the ground.

The tree, not very tall, I walked to the edge of the tree and looked back at the place where the fat base had fallen. I gestured with my hand, Luo Feng didn't know what I was doing, so he didn't bother me. Finally, I found a guessed direction, and I told Luo Feng that the knife should have flown out of this big tree.

Luo Feng was stunned, he laughed twice: "Fang Han, do you really think that someone threw the knife out to kill someone?" If you say that Fei Ji was hacked to death, I still believe that someone threw a knife out, but it is absolutely impossible to cut his throat. ”

I walked straight forward from the position of the big tree, and when I passed the place where the fat base fell, I stopped and asked Luo Feng to walk forward with me. Luo Feng was inexplicable, but he still did it, and soon, we walked along the straight line to the edge of the brick wall in the courtyard, Luo Feng couldn't help it, and asked me what I was going to do, I asked Luo Feng to observe this wall carefully.

The villa where Feiji lives, although it is economical, is relatively new. The walls are made of bricks and coated with a layer of smooth-looking cement. I searched for a while on the wall, and sure enough, I found the trace I was looking for, I pointed to the wall and asked Luo Feng to take a closer look: there was an irregular pit on the wall.

The crater is small and shallow, but it is already noticeable compared to the smooth walls around it. It looked as if someone had inadvertently hammered the wall with an iron nail, leaving an irregular pit.

"What is this?" Luo Feng asked me.

"When a knife is thrown, the tip of the knife hits the wall, leaving a mark." I said to Luo Feng.

This is a typical tool mark, and I immediately analyzed it through the comparison of models, which is the mark left by the collision between the tip of the knife and the wall. The so-called tool traces generally refer to the plastic deformation left by the contact between the criminal tool and the destroyed physical object. I am already familiar with most of the models of tool marks.

Luo Feng became more and more shocked, and he asked me blankly: "Is there really someone who can throw a knife and cut his throat accurately?" ”

I just laughed: "Who said that knives are thrown by people." What you just said reminded me that if someone is holding a knife close to Feiji, it is impossible for there to be no traces of struggle at all, so the only one who is close to Feiji is this knife. People can't do it, but tools can. ”

The small pit in the wall is the best proof of this. I approached the tree and gestured, speculating on where the knife would fly. That knife must have been thrusted with a very strong force to fly so far, and it still left a small hole in the wall. And this thrust, most likely, is elastic.

I simulated the situation: Hiki heard movement in the backyard, so he slowly walked towards the backyard with trepidation. However, as he passed through the grass, he stepped on some kind of prop switch in the grass, and then the knife from the tree was ejected and exploded towards Feiji's throat, slitting Feiji's throat and leaving a tool mark on the wall.

Luo Feng frowned, he still didn't want to believe it: "What kind of props or traps can cut the throat of the fat base so accurately." Moreover, the backyard is so big, how can the murderer ensure that Feiji will definitely get to the position of the switch and step on the switch? Luo Feng thought about it, and said: "Could it be that there is no switch at all, the murderer has been hiding in the tree, and after Feiji comes, the murderer will find a way to pop out the knife?" ”

I smiled, "It's just speculation, I haven't figured out what props or traps can cut someone's throat so precisely." ”

Luo Feng was stunned: "I'm not sure you're still laughing, it's getting dark, seventy-two hours, and it's about to be twelve hours, aren't you really in a hurry?" ”

I shook my head: "The murderer should be in a more anxious hurry than us, there is always a way to lure him out." ”

At this time, Luo Feng's mobile phone rang, and after listening to the phone, he told me that Daxi met Yungao today.

"It's Yungao again, it must be Yungao who asked Daxi to introduce those little gangsters into the village and interfere with us!" The more Luo Feng spoke, the more angry he became: "Yun Gao himself is not a murderer, and he has no one to protect, why does he keep hindering us!" ”

Luo Feng's words made my eyes widen: "I figured it out." ”
