This night is destined to be a sleepless night.

Many people are busy with this case, especially the three newcomers, this is their first time participating in the investigation of the case, and they all want to leave a perfect mark on their answers.

Ding Fan is no exception, although he doesn't have many clues in his hands, it is also very crucial, but he also has a bit of a headache for these evidences now.

In the past, as long as Yu Xiaobo showed Yu Xiaobo the traces pressed out of this kind of car, he would know the answer he wanted after ten minutes.

But now that Yu Xiaobo is not around, he can only find out a lot of information and compare it little by little.

Yu Xiaobo has seen the photos transmitted remotely, and the general shape of the car can basically be judged through the tire marks on the ground, but there is still no way to completely confirm the specific vehicle model, which requires more intuitive judgment from him.

However, Yu Xiaobo is not a vegetarian, and with this photo, he drew a general range for Ding Fan.

Although I don't know the origin of the wheel, but from the analysis of the tire imprint of the car, this tire should be produced domestically, and it can be concluded that this tire has not been replaced for a long time, and it is a relatively high-end brand in China.

In addition, he also helped Ding Fan investigate the approximate manufacturer of the tire texture, and determined how many car repair shops in Binhai sold this tire.

The results of the investigation before and after were really a bit unexpected by Ding Fan.

Because this kind of tire is not used very much in other cities, that is, it is used in the coastal city is unusually large.

Later, I learned that the manufacturer of this tire itself is near the coast, and it is no wonder that the amount of use was amazing.

It's just that in this way, the difficulty of the investigation is a bit greater, and it may be easier to handle it if there are many people, but now there are only three novices under Ding Fan who can use it.

Now there are no newbies, and they are checking the previous clues outside, and they may not be able to finish it in a short time.

After hanging up Yu Xiaobo's phone, Ding Fan took the opportunity to ask Huang Yao and Fu Lei how they were doing.

These two people went to the telecommunications company to investigate the phone call, and although the workload was a little larger, it was relatively safer.

What really worries Ding Fan is Fu Lei, the person he wants to follow up and investigate, but he is a doctor with psychological problems.

If this person is really the culprit of this case, then Fu Lei will inevitably have a certain degree of danger.

People with this kind of psychological problem have a strong defensive psychology and anti-detection ability, and when they encounter this kind of thing, they will generally react quickly.

And it's the kind of person who would rather kill by mistake than never let go of a dangerous person, these people have blood on their hands, and killing one person is basically no different from killing multiple people.

Although the progress of Huang Yao's investigation is a bit slow, it is relatively smooth, and it is already being carried out in an orderly manner, and it should be almost the same tomorrow morning.

But the problem was on Fu Lei's side, Ding Fan called him several times, but no one answered the phone.

This situation is not a good sign, Ding Fan has told them many times, the phone must be guaranteed to be smooth at any time, so that it is convenient to contact at any time, even if it is a PHS, there is really no money, he has found a way to match them first, who knows that the phone is in hand, and the person is gone in a blink of an eye, and no one has answered the phone.

This can make Ding Fan anxious, if this Fu Lei has some experience in handling cases, he can be more or less relieved.

After all, if an old police officer has a problem with the phone, he knows how to find some other means of contact, so he won't worry so much.

But Fu Lei is just a newcomer after all, he has no experience, and he can't even deal with temporary situations.

In addition, today, Ding Fan had a conflict with that Wu Zhirong, and this person could not guarantee that he would not attack this young man.

Ding Fan didn't tell the other two about this, but directly found Kong Jie and asked him to find a way to find Fu Lei's whereabouts.

However, this matter is really a bit difficult for Kong Jie.

Besides, when Fu Lei left today, he didn't say where he was going, he just reported to him, and he didn't even know as much as Ding Fan about specific things.

At this time, Ding Fan asked him to find a way to find someone, which was simply embarrassing him.

Anyway, Fu Lei's kid is also his subordinate, even if he didn't bring him out today, after all, he is a police officer on their coast, and he has to find a way to look outside after all.

And Ding Fan didn't completely hand over this matter to Kong Jie to investigate, and at the same time he asked the people around him to start all kinds of clues, but this clue is really not easy to find.

I don't know what Fu Lei thinks, there was no call back after leaving, and at this moment, even Yan Liqiu was pulled out by Ding Fan, calling all her eyeliner outside, and starting to look for Fu Lei like crazy in the whole city.

The only clue is now the clue that Fu Lei brought back before, the one named Du Haichao, a doctor from Binhai Central Hospital, if Fu Lei wants to investigate him, Bacheng will also go to the hospital to take a turn, maybe he can do some investigation from this direction.

As for where he was going and what he was going to investigate, I didn't know at all.

This requires a little luck, and all Ding Fanxin can do is wait for news, he can't do anything else.

But an hour passed, and the phone in Ding Fan's hand kept calling, hoping that this kid could respond to him as soon as possible.

However, this hour has passed, Ding Fan's mobile phone has run out of battery, and he has changed several batteries, but he still hasn't made the call, as if this Fu Lei has evaporated in the world.

In an hour, the battery was out of power, and Ding Fan really couldn't wait, after changing the battery, he picked up his clothes and walked outside, telling Yan Liqiu that he would notify himself immediately if there was any news.

Ding Ning has been living here with Ding Fan, and when he saw that he was going out, he secretly sat in the car with him.

Ding Fan glanced at the little girl beside her, thought about it for a while, and didn't say anything, anyway, if she wants to follow, she can follow!

When he was about to go out, Yan Liqiu suddenly ran out of it and hurriedly said to him: "I contacted a classmate of Du Haichao before, he said that a policeman had looked for him today, and after the two chatted for a while in the afternoon, the policeman left in a hurry." ”

Ding Fan sat in the car, his hands tightly grasped the steering wheel, frowned tightly, thought for a while and asked, "Do you know when it is?"

In terms of time, it is the only way that Ding Fan can use.

After all, the time when Fu Lei left the police station today should have been a little more than a little later, and it has been eight hours until now.

For such a long time, it is not easy to judge his range of motion.

And Yan Liqiu had thought about this before, and he asked these details clearly.

"I asked, and I didn't go until about three o'clock in the afternoon, but I didn't see anyone at that time, and they were also working. ”

Later, the policeman deliberately hung up a number outside, just to ask the two about Du Haichao's news, so the doctor was very impressed with him, the time when the two met should have been almost four o'clock, and it was less than half past four when they left. ”

It's more than four o'clock!

While thinking about this timeline, he took out a map from the car.

"Do you know which hospital it is?"

Yan Liqiu looked at his movements, and seemed to have thought of what he was going to do next, glanced at the top of the notebook and said, "Binhai City ENT Hospital, in the north of Tianhong Street in the north of the city. ”

Ding Fan got out of the car directly, opened the map, took out a pen and carefully marked it twice, and used his finger as a ruler to briefly draw on it, and a relatively simple circle was drawn.

At about half past four in the afternoon, someone else had seen Fu Lei, proving that he was still safe during this time period.

But at about seven o'clock in the evening, Ding Fan called him for the first time, but found that the kid's phone was no longer available.

It was about three hours in between, and until now, almost four hours have passed.

According to the speed of the car in the city, four hours is completely enough to drive the car out of the city.

If you want to find someone, I'm afraid it's a bit difficult.

However, in the direction of the north of the city, the best option to leave the city must be the north gate, which is enough for half an hour's drive.

If the other party wants to be unfavorable to him, he will definitely transport the person out of the city as soon as possible.

It's just that after they leave the city, where do they go back?

"Check who Fu Lei's phone last called, and find a way to contact this person. ”

Ding Fan thought about it for a long time, and felt that it was a bit reluctant to find someone in this way.

Only the last contact through the phone, at once to determine his location.

However, the direction of this investigation is a bit worrying about Yan Liqiu, after all, the communication company is off work at this time, she just wants to investigate, I'm afraid it is a little difficult, and it is very likely that things will get bigger.

But looking at Ding Fan's eagerness now, she also knew that it was not appropriate to ask more, so she could only sigh and turn around to go back to investigate the matter.

Ding Fan also had to stop his movements and wait for news from Yan Liqiu's side.

Just when he was extremely nervous, his palms suddenly softened, and a pair of small hands reached into his palms.

Ding Fan turned around and saw that Ding Ning was standing beside him at this moment, holding him tightly with his little hands, with a worried look.

Not to mention, Ding Fan was still a little nervous and restless before, but he was pulled by Ding Ning in the palm of his hand, and he really calmed down a lot.

Soon Yan Liqiu ran out of the room, but at this moment her face became a little nervous, obviously the clues obtained from the investigation were probably not good news.

"The last contact I found was a woman named Jiang Wei. ”

"This Jiang Wei is Du Haichao's ex-girlfriend, when it was almost five o'clock, Fu Lei called her, saying that he wanted to find her about something, but Jiang Wei waited at the door of the hospital for a long time and did not see Fu Lei, and when he called, no one answered on the other side of the phone. ”

"Jiang Wei works in a dental clinic, and the location is also in the north of the city, less than a kilometer away from the ENT Hospital, judging from the time, Fu Lei is very likely to be waiting outside the dental clinic when he called, but when Jiang Wei came out, Fu Lei encountered something wrong, so Jiang Wei did not see anyone. ”

I have to say that Yan Liqiu's speculation is very likely, because Ding Fan also thinks so.

"I can't wait, call the people in the room, except for Ivan who stays with you, the others will go out with me to find them. ”

"Mobilize all your subordinates, find this Du Haichao for me, I want to know where he went after half past four in the afternoon, where was the last place he appeared, find any news, notify me as soon as possible!"
