After a day of traveling, when he returned to the station, Ding Fan was almost exhausted.

It seems that he has never been so tired before, maybe it is because of the people he saw outside today, each of them made him rack his brains to deal with it.

The reason why I feel tired is more because of the feeling of tiredness in my brain.

After sleeping backwards for a night, Ding Fan, who got up the next morning and was full of energy, returned to the police station.

And Ding Fan, who was not at the police station all day yesterday, was still thinking in his heart that if he didn't come back yesterday, would he be crazy to find himself here.

After all, everyone still has some things to report on the case, and if they don't make up their minds, and no one calls them, will something happen?

As a result, Ding Fan arrived at the police station and found that he was still thinking a little too much.

Since yesterday's police station went on a mission, not only has nothing happened here, but no one has even returned.

The investigation of the case itself is not so fast, most of the time, it is after doing a lot of investigation before there can be some news, and after the new information is found, it has to go through a lot of verification.

Among the police officers sent out, there were not many people in each group, that is, there were a little more people on Hao Xiang's side, but they were scattered in a relatively large area, and they didn't think they would be able to find the clues back so quickly.

In the entire Second Criminal Investigation Team, only Gu Nian is still in the office, plus two civilian personnel.

To be honest, Ding Fan was a little worried about this case.

After all, the person involved in the back is likely to be Qiao Laosi.

In case of any obstacle they encounter while investigating outside, there is a high chance that something will happen.

"Gu Nian, is there any news from the other groups?"

Ding Fan stood at the door of the office, stopped for a moment, and asked Gu Nian.

And Gu Nian seemed to be busy with the matter at hand at this time, and he was really in no mood to deal with him, so he shook his head without even raising his head, which was an answer to him.

Seeing that Gu Nian was busy now, Ding Fan had nothing to ask, so he had to turn around and go back to the office first.

Who knew that he had just returned to the office, and before he was hot, Gu Nian broke in.

"Boss, I've got a clue here. ”

"Tell me about it. ”

Ding Fan glanced at her, stretched out his hand and motioned for her to sit down first.

"You asked me to check on murderers with similar methods, I contacted several police stations around me yesterday, and even the prison also said hello, and I really found a few people with similar methods. ”

Gu Nian didn't have time to sit down, so he opened the document bag in his hand first, took out all the documents contained in it, and put them on the table one by one.

Ding Fan stretched out his head to take a look, and some of the information even had photos on it.

But in most of the sources, there are no photos attached to it.

After looking at the days, I suddenly understood the reason.

Many cases have occurred for more than ten years, and at that time, the cameras on the forensic side were not fully popularized, and many cases did not leave photos of wounds at all, but the case handlers made a little introduction in the way of verbal description.

"In ten years, there were seven similar cases, and the next four had photographs. ”

Ding Fan stretched out his hand to take these photos in his hand and compared the wounds on Deng Xichao's body one by one.

"Bringing up the files of these people, I will find the people on the medical examiner's side and ask them to come and have a look, hoping to see something. ”

"Boss, in fact, you don't have to go, I've already asked, the photo is not very clear,

After reading it, the forensic doctor said that there was no way to analyze the internal knife wounds, so he could only go back and find the file and look at the previous forensic report. ”

Ding Fan looked at the photo in his hand, and cracked his mouth a little embarrassed.

To be honest, I can't really see anything in these photos in my hand, not only is there no color, but even the images look a little blurry, not clear at all, it's weird that this thing can be seen.

Just when Ding Fan looked at the things in his hand and was a little worried, Gu Nian suddenly smiled and stretched out his hand to push a document in front of him.

"I'm very suspicious of this man now. ”

"Tang Ji?"

Ding Fan reached out and picked up a document on the table, looked at it very suspiciously, and finally turned his eyes to Gu Nian's body.

To be honest, when Ding Fan saw this document, he was really a little curious, after all, the things on it only had a little bit of the prisoner's family background, and a little bit of social relations.

I don't know where Gu Nian saw the problem, anyway, for the time being, Ding Fan can't see that there is any problem on it.

But Gu Nian will not have no basis at all, so he will directly say that this person has a problem, right?

Thinking about Gu Nian's problem of always liking to sell guanzi, Ding Fan was relieved at once.

Eighty percent of this girl is waiting for herself to ask her!

"Say, you must know something, and you can't tell anything from this information. ”

When Gu Nian heard that Ding Fan had already started to ask, it seemed that his vanity had been greatly satisfied, and he immediately laughed.

"At first, I didn't think about this person, or when I asked Mr. Jiang about these photos today, I listened to him. ”

Gu Nian said that at first, she just wanted to find Dr. Jiang in the forensic office to take a look at a few photos in her hand, after all, this thing itself is their specialty.

But from these not very clear photos, it is difficult to see what wounds are on them, and it is even very difficult to distinguish the murder weapon.

So Dr. Jiang tried a way to find out the cases that these people had done before, and used the forensic results of their previous cases to make an analysis.

And the final result turned out to be a person named Tang Ji with the highest ability.

The information shows that this person named Tang Ji used to work in the farm, and the cattle and sheep raised in the factory were all in charge of the slaughter in the end.

He has a nickname, and everyone calls him Tang Yidao.

It is said that with a single knife, he can cut the aorta of these beasts and bleed them, and the score is exactly right, and the movements are fast and accurate.

And the case he committed was twelve years ago, when he was out drinking and playing cards with others, because someone said bad things about his wife, he was angry for a while, had a quarrel with someone, and finally made a move.

Fortunately, a police officer arrived at the scene in time and separated the two, and Tang Ji was only slightly injured.

It is said that this is not a big deal, but the person with an unclean mouth, who didn't know if he drank too much or what, kept provoking, saying that he didn't believe that there was any ability to make a soup and a knife.

In the end, he stretched his neck and said that if Tang Yidao really had this ability, he would give it to himself, and he would not be responsible for nonsense.

The result can be imagined, this soup season was originally angry with him, and in addition to this person's constant provocation, he finally ......

It turns out that Tang Yidao's name was not called in vain, and after a knife, this shouting guy was picked off by Tang Ji and broke the arteries and blood vessels above his neck.

Everyone present at that time was stunned, even Tang Ji himself didn't expect that he was just impulsive for a while, and he actually caused such a result, and looked at his hands in disbelief.

Afterwards, Tang Ji didn't think about running, but obediently followed the police back to the police station, and the case was almost the same time from beginning to end.

And the reason why Dr. Jiang remembers this case so clearly is actually a bit of a coincidence.

Tang Ji's knife, although it seems ordinary, can be miraculous in the eyes of these forensic doctors.

Under the knife, whether it is depth or strength, it is very accurate, and the knife almost does not hurt other blood vessels, except that the aorta is broken, and the wound on the outside is very small, only less than a centimeter in length.

Many forensic doctors can't do this kind of method, even Dr. Jiang, who has been operating for many years, does not have this ability.

For this reason, he also deliberately found this soup season and asked how to practice this skill, and after returning home, he really tried many times, so he remembered this matter very clearly.

Ding Fan heard from the beginning to the end, and finally found that the problem seemed to appear at a point.

"Twelve years ago, this Tang Ji's age seemed to be about thirty-seven years old, and he was sentenced to ten years, which means that he came out two years ago, so this year he is almost fifty. ”

"Boss, do you want to say, after so many years, will the ability of this soup season be wasted?"

Ding Fan nodded, he did have this idea in his heart.

Ding Fan himself has been practicing martial arts all year round, and he knows very well that it is not very difficult to master Tang Ji's skills.

The real rarity is the long hours of practice over the years, which, combined with his work, itself has the opportunity to help him practice his strength and accuracy.

But for ten years, he has been in prison, how much can Tang Ji's kung fu remain?

"Isn't this normal? Tang Ji is old, and his kung fu is a little worse, so this time he left a long knife wound on the deceased's body, which is not a conflict at all!"

"It makes sense, but the motive is that it's for money? Or someone knows his ability, so he wants to ask him to kill people, but his methods themselves are very unique, and after comparing such wounds, we can easily lock on the murderer, is it necessary for him to do this? In fact, if you want to kill someone, you don't have to be so troublesome at all, the deceased has already used chloroform before being killed, and there is no ability to resist before death, if you want to kill, you can do it in any way, why do you want to do this, isn't it better to find someone with a clean foundation?"

Ding Fan's question completely stopped Gu Nian.

After just listening to Dr. Jiang's words before, he used all his doubts on this soup season, and he didn't think about these problems at all.

Now it seems that there are really a lot of irrationalities in the problem.

"Don't be discouraged, what you find is not completely useless. ”

Seeing Gu Nian's lonely face now, Ding Fan suddenly understood her thoughts, poured a glass of water with a smile, and put it in front of her.

"In this case, find out the home address of this Tang Ji, and then call someone from the police station to check on the situation of his home. ”

"Didn't I go to the police station?"

Ding Fan smiled, shook his head at Gu Nian, reached out and took out a piece of paper, wrote something on it and handed it to her.

"You call the prison to check, during Tang Ji's sentence, who walked with him closest, and his age should not be very old, now he is less than thirty years old, his hometown should be local, check if there is such a person." ”

The two were talking about the direction of the investigation behind, and Yu Yang and Zu Zhengwen came in from outside, looking sweaty.

There is no need for them to say anything, just look at the expressions on their faces to know that this day and night is estimated to be in vain.
