This inexplicable bullet casing was picked up by Jin Jian from the outside, and it is said that he knows best where he found this thing.

Besides, this Jin Jian and Qiao Dayong are the same kind of people, and they always have a strong ability to identify clues that are accidentally discovered.

It was discovered by Jin Jian, and he carefully sent the thing to Ding Fan's hands, and it was obvious that he already had a little idea of his own.

After all, a person's vision is still limited, and they still need to brainstorm, maybe in the eyes of others, this case is not so complicated.

It was after thinking of this that Ding Fan returned to the office for the first time and called Jin Jian in, just to ask him what he thought about this bullet case.

It's just that after Jin Jian saw this bullet case, he shook his head and said a little embarrassed: "Actually, captain, I don't know if this thing is useful, I didn't think about it so much at the time, I just felt that this bullet case seemed to be similar to the bullet case number we always kept, so I brought it back, and I picked it up at the place where we were assessing." ”

Ding Fan frowned and asked rhetorically, "You mean, near the old building?"

If Ding Fan is not mistaken, the front of the old building seems to be an open space, and if there are bullet casings in that place, it is said that it is not difficult to find.

But when he stepped on the spot to set the position before, Ding Fan walked back and forth there several times, and he didn't find anything on the ground at all, so if he said this, it was impossible for anything to be there.

"Not the main entrance, but in the window position on the side. As soon as he heard Ding Fan talk about the main entrance, Jin Jian hurriedly said: "At that time, the bullet casings in our hands were basically recovered, only Zhou Li's one was less, he said that the last shot was not fired by himself at that time, it was just a moment of nervousness and pulled the trigger, he was hidden in the position of the side window, as soon as the gun rang out, in less than two minutes, he was arrested, and he didn't know where the bullet casings fell for a while, we all helped him find it for a long time, and finally found one more." ”

As he spoke, Jin Jian stretched out his hand and pointed to the bullet casings on the table.

"What do you think?" Ding Fan frowned, thought about it for a long time, and still didn't understand why the warhead appeared here, and the time was still half a year ago.

You must know that at this time, Wang Jianguo has been dead for more than half a year, and his gun is not outside, who will shoot outside?

The most critical point is that Ding Fan had already asked Lu Zhi before, this thing has been kept in the gun hangar, and it was sealed by the leaders with their own eyes, so it is impossible for it to be left outside.

There are more and more mysteries in front of me, and no matter how you think about it, you feel that there is too much fog in this matter.

Since he couldn't figure it out, Ding Fan decided to investigate from another direction first.

"You wait here, I have something to arrange for you. As if he had suddenly thought of something, Ding Fan suddenly stood up, walked outside, and called Chen Siming of the first team in.

"Chen Siming, this is Jin Jian, do you know him?" Ding Fan reached out and took a piece of paper, stretched out his hand to draw on it, and said without raising his head: "Give you a task, you caught Zhou Li yesterday, right? You and Jin Jian were running around the scene, and they were finding the location of the bullet casing, imitating the position and posture of the gunman at that time.

Also, if you look at this room and check it carefully, I think there is something wrong with this song room. ”

Although Chen Siming didn't know anything about the bullet shells, since Ding Fan had already said so, he would just do it directly, anyway, he was used to it, no matter what he said, he just did it, as for the reason, he would naturally know when he came back.

So Chen Siming didn't say anything, reached out and took the location map drawn by Ding Fan, turned around and pulled Jin Jian to set off.

Although for the time being, only a bullet shell was found here, and it was not an important thing, but Ding Fan felt that things were not so simple.

If the shell is just a normal shell, or if it is registered as lost, all this is easy to do.

But the final identification of this bullet is indeed from the police gun, or is it a gun that has been sealed for a long time, what is hidden in it?

Why would anyone use this gun?

What do you do with this gun?

The most important thing is how the gun left the police station, could it be that the gun was not mothballed in the first place?

Ding Fan has already been able to discuss with Lu Zhi, and hopes to communicate with the leaders above if he can open the seal and check if the gun is still there.

In fact, Lu Zhi is more anxious than Ding Fan now, and he has already gone to the leader to ask about this matter, just hoping to get a little news as soon as possible.

Ding Fan waited in the office for more than an hour, fidgeting back and forth, hoping that Jin Jian's side could send news back as soon as possible, or Lu Zhi's side could come down as soon as possible.

Just don't ask Ding Fan to be idle and have nothing to do now, as long as he sits down, Ding Fan's mind will think of this case.

Just when Ding Fan was already a little dizzy from the office, Jin Jian finally came back from outside, and the two of them rushed back from the outside with a sweaty face, and that eager look made his heart lift up as soon as possible.

"Chief, there was a discovery, and sure enough, there was a discovery. Chen Siming hurriedly ran in from outside, and didn't even close the door as soon as he entered, so he hurriedly said to Ding Fan: "Just like you thought, I really found something in the room, you see." ”

As he spoke, Chen Siming took out a small evidence bag from his body, and then said: "This was found on the wall, I carefully buckled it off from it, and I have just asked Section Chief Qin to show it, although I can't be completely sure that it is human blood, but this thing is a piece of blood coagulated and formed, and basically didn't run away." ”

Ding Fan frowned, thought for a long time, slowly sat down, and asked in a low voice, "There are blood stains at the scene, how much?"

Chen Siming scratched his head, glanced at Jin Jian behind him a little embarrassed, and motioned for him to talk.

Jin Jian nodded, walked up to Ding Fan, and said: "Most of the blood is on the wall, the location is on the wall directly opposite the window, there is a little on the ground, it has not been tested for the time being, you must know that the results are estimated to wait for a while." In addition, I found a little drag on the ground and the doorway. ”

Ding Fan squinted his eyes and glanced at Chen Siming who was standing at the door, and suddenly remembered that when Zhou Li was arrested before, he seemed to be trapped as a zongzi, could it be that he caused it at that time?

As soon as Ding Fan's eyes came, Chen Siming immediately seemed to understand,

Hurriedly said: "It's not me, after I caught Zhou Li, I walked through the main entrance, although the window is convenient, but there is a small drainage ditch under the window, and I can't carry people through at all." ”

He nodded and said to Jin Jian, "Go on, what's next?"

"According to my judgment, the victim should have been face to face with the person who used the gun, the distance between them was less than 20 meters, and the blood spots on the wall were in a state of splattering, and it seemed that the location where the victim was shot at that time was probably the chest or something. Jin Jian took a deep breath and said everything he saw, as well as his own judgment.

After finishing speaking, he looked at Ding Fan a little nervously.

And Ding Fan closed his eyes directly after listening to the analysis of all this, and seemed to have begun to sketch the situation at the scene in his mind.

"The distance between the two people, about 20 meters, the height of the victim should be more than 1.75 meters. Ding Fan muttered in a low voice: "Whether you are shot in the front or in the back, it will eventually leave a large area of blood on the wall, and the most dense blood spot should be the location where the victim was shot, how high is that position from the ground?"

Jin Jian looked at Ding Fan in surprise, recalled it for a while, and then said, "It's probably at the position of my chest, that is, about one meter six." ”

"That's right, if there is no trace of blood on the wall, if there is no trace of being scratched by something, the height of the deceased should be around 1.8 meters. Ding Fan glanced at Jin Jian and seemed to see his puzzlement, so he said: "The height of the victim should be a little taller than you, and after the blood is sprayed, it is sprayed out in a parabolic shape, so it is located on your chest, so the wound of the injury may also be at the height of your chin, which means that the victim may be a head taller than you." ”

Jin Jian suddenly realized: "I understand, judging by the height of the deceased, we can still find the position of the deceased after he fell to the ground, reverse comparison, we should be able to find the exact standing point of the gunman at that time, we can look around, maybe there are some clues." ”

Ding Fan nodded, smiled, and said, "Yes, it's very quick to enter the role! But don't forget the scene, since the murderer took away the body, there will definitely be something left at the scene, it depends on whether we can find it." ”

As soon as he said this, Jin Jian immediately felt full of confidence, this was the first case he had experienced, and the degree of seriousness was definitely super high.

"In addition to the bloodstains, there are also the drag marks you mentioned at the scene, which may give us a clue. Ding Fan said as he stood up and said to the two people beside him: "The entire cement factory covers an area of almost eight square kilometers, and if you search thoroughly, it will take a lot of time! ”

Ding Fan was arranging here, and the phone on the table suddenly rang.

He was still wondering who called him at this time, but after hearing the phone, the whole person was stunned.

"You go to the scene first, start the search directly, the director told me to go over, and I will go over when the matter is over. Ding Fan said to the two of them with a slightly unsightly face, turned around and went directly to Lu Zhi's office.

I don't know why, I just listened to Lu Zhi speak, and I always gave Ding Fan a very bad feeling.
