In fact, these things can be seen in the on-site simulation.

Ding Fan turned around slowly, glanced at the direction of the toilet, slowly lowered his head, made a gesture of putting down something, suddenly turned around as if he had taken something, rushed to the door of the toilet quickly, raised his foot and kicked over, waved his empty arm, waved it in front of him, and wiped it on his face like a decent one when he was done.

"It's done, from entering the door, to killing people, leaving with money, the whole process should be like this. Ding Fan walked out of the toilet, took a deep breath, and said slowly: "In the process, you all saw something, let's talk about it!"

"Footprints, what are the footprints left behind?" Zhao Wu's eyes lit up, and he suddenly said: "At that time, when I arrived at the end of the field, there was a footprint here. ”

Ding Fan walked over, stretched out his feet and stepped on that position, thought for a while, and said: "Judging from the location of the footprints, the murderer put the box containing the money here at that time, and after the killing, he planned to leave, so he stayed here for a while and left with the box. ”

This case, in fact, in Ding Fan's opinion, is simply simple.

Because the murderer obviously didn't want to kill in the first place, but after entering the door, he seemed to be stimulated by something, most likely because of money, or because of something else.

In the end, he made a temporary decision, killed people, and then planned to leave with money.

It is precisely because of this that he left too many traces at the scene, did it to three people in a row, and finally left too many murder weapons at the scene, and the most ridiculous thing is that he did not take away the three murder weapons and dispose of them, but threw them at the scene.

According to the investigation of Zhao Wu's subordinates, as well as Gu Nian's understanding of Zhang Hanchao's wife, they finally learned the reason why they went home that day.

It's not because Zhang Hanchao has any habits, after taking the money, he has to count it at home, but because he has serious gastrointestinal problems, that morning just because the clock time at home was a little inaccurate, and he didn't have time to take medicine when he went to work, so he went home halfway, planning to go back after taking medicine.

But he never thought that he had only been in the toilet for a while, and two colleagues outside were killed, and even he himself did not escape this catastrophe.

On the night of receiving the report, Ding Fan made a simulation for everyone at the scene, restoring the scene of the previous killing, and at that moment, Ding Fan actually had a certain direction in his heart.

It's just that he didn't say it, there are still two and a half days left, and during this time, Zhao Wu and the others can be given a little chance, maybe they can solve this case by themselves!

However, no one thought that Ding Fan planned to train Zhao Wu, but he didn't realize it himself, so he led people to start an investigation overnight.

Until noon the next day, Zhao Wu did not lock up the suspect, but actually found all the clues and evidence, and the table in the entire conference room was full.

Of course, in this case, there is also a group of big men with panda eyes.

When Ding Fan walked in, Zhao Wu's eyes were already a little dull, if it weren't for the fact that he was holding a chili pepper in his hand and constantly biting to refresh himself, it was estimated that he would have fallen asleep by this time.

"Did you read it last night?" Ding Fan looked at the people sitting on the ground with a smile, and he really didn't know what to say about them.

As soon as Ding Fan spoke, Zhao Wu immediately came to his senses, as if it was more effective than the chili pepper in his hand, and hurriedly got up from the ground and said, "Boss, see what we have found?"

Zhao Wu held a black leather box in his hand, sent it to Ding Fan, and said with a smile: "I have found someone."

It's settled, yesterday Zhang Hanchao used this suitcase to take the money away, and I found it in the grove behind the community. ”

Ding Fan just glanced at this delicate little box, and without even stretching out his hand, he said, "Did the trace examination department say anything?"

Ding Fan asked, Zhao Wu was directly stunned, and finally said a little uninterestingly: "I sent it before, but the trace examination department is now busy and crazy, so I was asked to put it aside first, and I turned around and came back to help me do the test, but time waits for no one!"

The trace examination department here of the Public Security Bureau is already the most well-equipped trace examination center in the entire region, not only to do trace autopsy for the criminal police team, but also to send all the districts and counties below that cannot do trace examination, and the usual work is also very busy, and it is normal that it is too late to do a test for him.

"Then go straight to fingerprinting. Ding Fan frowned, stretched out his hand and pointed to the handle of the box, and then pointed to a very clear fingerprint on the box and said: "If this fingerprint is not left by you, it is very likely that it was left by the murderer. ”

When Zhao Wu heard this, he hurriedly kicked a police officer beside him, reminded the sleepy young man, and gave him the box.

"Yesterday, I asked you about the fingerprints on the door lock, is there any news over there?" If Ding Fan was not wrong, the murderer would have left the fingerprints on his hand when he left.

"I've asked for everything, and I've even left someone at the trace department, and I'll come back as soon as I get the news. When he said this, Zhao Wu was still a little proud, obviously very satisfied with his arrangement.

It's just that Ding Fan didn't feel that he had anything to be proud of in this arrangement, and he dispersed the existing manpower, which was undoubtedly increasing the workload for their current people.

As soon as he talked about this case, Zhao Wu simply threw himself to the ground for Ding Fan's admiration, and after turning around the scene, he could think of the whole process of the murderer's killing, as if he was killing people with his own hands.

But Ding Fan didn't care about what he did at all, but cared more about when Zhao Wu would be able to pay attention to that point.

From the transcript sent before, Ding Fan had already seen a flaw, plus he saw the scene with his own eyes yesterday, in fact, he already had an object of suspicion in his heart, if Zhao Wu hadn't noticed this point all the time, then in the end he would inevitably feel faceless.

"Okay, the investigation on your side continues, physical evidence is very important, don't forget about human witnesses. Ding Fan could only remind him as vaguely as possible, as for whether he could understand it, it could only depend on himself.

After leaving the conference room, Ding Fan was still a little uneasy and went directly to the trace examination department.

When others go to the trace examination department, they are a little evasive, and they are very careful when entering and exiting, for fear that they will touch or mess up the things inside, and cause some trouble to others.

On the contrary, after Ding Fan came, he came in and out very casually, and walked into Qin Lu's office with a familiar car, and asked straight to the point: "Have you seen all the things you sent?"

Qin Lu kept busy with his hands, and asked without raising his head: "What is it?" I haven't finished my hands now, when will you send things again?"

Ding Fan took a deep breath and said, "It's yesterday's case, the fingerprints on the murder weapon should have been extracted, right?

Qin Lu nodded, casually reached out and took a comparison report from the side and handed it to Ding Fan, and said softly: "The expected things, the fingerprints on the murder weapon, and the fingerprints on the door, are all."

It's the same, it should be left when the murderer leaves, when the door is opened, what's the problem?"

Ding Fan held the result of fingerprint comparison in his hand, laughed, and said, "No problem, no problem at all, by the way, help me compare this too." ”

As Ding Fan spoke, he took out a transparent adhesive paper from his body, and a very clear fingerprint stood on it.

"Where did it come from?" Qin Lu stretched out his hand and took the thing in his hand, frowned and asked Ding Fan: "You should know that even if the fingerprint is correct, you must have your own fingerprint as a reference standard, otherwise even if you find the fingerprint, there is still no way to determine the identity of the murderer." ”

Of course Ding Fan knew this, otherwise he wouldn't have extracted this thing.

The things were handed over to Qin Lu, and Ding Fan was relieved, holding the appraisal results in his hand, he turned around and left.

Looking at the back of Ding Fan leaving, Qin Lu could only shake his head helplessly in the end.

For Ding Fan's way of working, she has gradually begun to get used to it.

Seeing that the truth of the case was in front of him, Ding Fan could already feel a little more relieved, returned to the office, and began to study the information in his hand, waiting for news from Zhao Wu's side by the way.

It's just that Ding Fan seems to be born with a hard life, and just after returning to the office, Gu Nian hurriedly ran back from outside, and said with admiration: "Boss, you are really a god, the thing is really there." ”

Ding Fan nodded, glanced outside, and said with a smile: "Have you changed anything?"

Gu Nian said with a sly smile: "The thing has been returned to the original owner, and a bunch of it has been exchanged for him, this is a receipt." ”

As a result, Ding Fan nodded, put the things away, and said with a smile: "Have you checked that thing?"

"I found out, this person has no special background, and this house was temporarily lent to him by the factory, and they didn't say it, as if they were a little evasive. Gu Nian closed the door of the office, sat in front of Ding Fan, lowered his voice and said: "Later, I specially asked someone about it, it seems that some time ago, when he was working in the factory, there was a little accident, and after the factory called someone to investigate, the conclusion given is that the cause of the accident is his own illegal operation, although the factory paid the medical expenses, but he didn't get anything else, and now his matter has become a joke in the factory." ”

After hearing this, Ding Fan thought for a moment, leaned back in his chair, pondered for a while, and asked, "Does this matter have anything to do with Zhang Hanchao?

As soon as she talked about this, Gu Nian, the little girl, suddenly laughed and said to Ding Fan: "Do you know what they call him in the factory? ”

It is said that there is nothing wrong with Zhang Hanchao.

After all, a person who is strict in doing things and absolutely abides by the rules and regulations is not wrong in itself.

Because of this, the director of their factory gave him such an important position in the finance department.

If you are the factory director yourself, you will definitely find such a person to watch the money for yourself.

It's just that I can't turn, and sometimes I don't know how to improvise, and I end up getting into trouble.

"Notify the police station, arrange a few people, and publicize it in the community, the people have been caught, and the blockade can be dismantled in these two days, and then you will have to work hard for two days. Ding Fan said expressionlessly: "If my estimate is not wrong, he should be going to do it tonight." ”
