If Jiang Lin is really a criminal suspect, even if Mu Yuan has a variety of means, without knowing Jiang Lin's exact whereabouts, once he knows that he has been targeted by the police, it will undoubtedly be much more difficult to arrest.

Mu Yuan hadn't been staring at his notebook for too long, and the waiter in the store had already come up with all kinds of seafood delicacies.

"Come on, everyone, eat well! This is the difference between our coastal city and your inland city, and the seafood can be managed. Qian Hongxian said happily.

Mu Yuan naturally wouldn't refute this, because he had already picked up a big crab and fiddled with it......

None of these seafood varieties are expensive, but as Qian Hongxian says, seafood is a big advantage in coastal city dining because it is fresh enough.

"It's a pity that today is a working day, so you can't drink, otherwise you can get some foreign wine with seafood, and it will taste good enough." Chen Jun also said on the side.

"I don't like to drink. Mu Yuan said very straightforwardly.

"Well, it's actually good to have a drink once in a while, it can both set the mood and bring you closer. Qian Hongxian said, "However, working hours are really not suitable for drinking, those of us who handle cases must keep a clear head, and it is easy to make mistakes when drinking." ”

Mu Yuan nodded approvingly, but ...... He still doesn't like to drink.

While nibbling on crabs and prawns, while listening to Fan Yitong and Qian Hongxian chatting nonsense, it was quite pleasant.

I have to say that Fan Yitong is not very old, but his communication skills are very outstanding.

The age gap between him and Qian Hongxian, the deputy captain, is nearly ten years old, and he is just a policeman, and the other party is a leader, but he has no stage fright at all.

With him alone, he can completely hold the audience.

Mu Yuan is also happy to see it, because he is not a person who likes to chat, and he is a person who is easy to talk to death.

At this moment, Mu Yuan is indeed very much like a person who is reincarnated by a starving ghost, who only cares about eating.

Half an hour passed, and the speed of Fan Yitong and the others' meals slowed down significantly, but Mu Yuan was still as fast and steady as ever.

"Xiao Mu, it seems that you like to eat seafood very much. Qian Hongxian's smile is very sincere, after all, the dishes selected by the host can be recognized by the guests, which is also an achievement.

Mu Yuan raised his head, smiled shyly, and said, "Yes! I really like to eat." ”

"If you like it, eat more! We have enough seafood here. Qian Hongxian said.

Mu Yuan then nodded.

Suddenly, he suddenly raised his head, his eyes a little confused, as if he was thinking about something.

"What's wrong?" Qian Hongxian asked in astonishment, could it be that he ate oysters and bit out the pearls?

Mu Yuan said: "Brigade Qian, what is the situation of the face recognition construction on your side? Can you search the movement trajectory of people through faces?"

The Qian Brigade smiled bitterly and said, "This is too difficult, let alone us here, even Kyoto and Shencheng are estimated to not reach this level." In the past, I heard from technicians that the construction of face cameras has high requirements for places, angles, etc., and if the recognition rate is too low, it will not be of much significance. Although we have built a lot of face cameras here in the past two years, it is impossible for everyone to form a trajectory of activities, unless the suspect often goes in and out of crowded places, it is possible that a person will not be able to leave a face for a year and a half. ”

Mu Yuan had to admit that this was a fact, and the situation in Xihua City was similar to that here.

He frowned.

After a while, Fan Yitong suddenly said: "Brother Yuan, in fact, you don't have to worry too much about this matter, if you want to find someone, you don't necessarily need to monitor, isn't this person still using a mobile phone, let's just let the technical investigation department help?"

The Qian Brigade also said: "That's it, they are professional in this area." As long as the general range can be determined, it is completely possible to squat and wait. ”

Mu Yuan nodded, he couldn't think of a better way for the time being.

Just now, he confirmed the time of the last call between Zhang Kaian and Jiang Lin, which was around 7 p.m. two days ago. Zhang Kai'an opened a restaurant, and he should be in his seafood city at that time.

This is also the main reason why he wants to come to Zhang Kai'an's restaurant to eat - I want to listen to what he said on the phone with Jiang Lin by revisiting the picture of Zhang Kai'an on the phone.

So just now, Mu Yuan asked Xiao Mao to sneak into the place where Zhang Kai'an was, and then used the time regression charm to find the place where he was talking to Jiang Lin two days ago, and then eavesdropped on some of the calls.

The chivalrous value of the flower is quite a lot, and it took a full thirteen seconds, and the result is ...... The two sides just said a few nonsense, which was meaningless.

Before that, Mu Yuan had already asked Xiao Mao to go around the big stone road, but he also found nothing.

It is true that the accurate time can be located in the call record, but it is impossible to determine the exact location, after all, the coverage area of the base station is large, and in terms of population density on the side of Haibo City, it is easy for a base station to cover tens of thousands of people.

As for his nose, it is even more useless in this case.

After all, he didn't know the suspect's breath, and without a reference, he couldn't operate it at all.

As for other trace examination techniques and criminal mind profiling techniques, this is not to mention.

It seems that apart from the method Fan Yitong said, there is really no better way to think of - he must also admit that the method Fan Yitong said is the most commonly used method in the process of police arrest.

When the pleasant meal was about to end, Qian Hongxian got up and went to pay the bill, and turned back after a while, looking at Fan Yitong with a pair of eyes with disgust.

"Why did you settle the account? I'll just tell you how you sneaked away just now. ”

Mu Yuan looked at Fan Yitong with a pair of eyes, and was a little puzzled, when did this guy pay the bill?

Fan Yitong said with a smile: "Brother Qian, don't be angry! We don't know how many days we have to work here for a few days in this case, and there will be more places to disturb in the future, and you are afraid that you will not have a chance to treat you! Moreover, we came to your side to handle the case, and you are helping us, so why do we have to invite you for this first meal?"

"I can't say you!" Qian Hongxian muttered, but he didn't argue anymore, after all, the accounts have already been paid, so he can't give the money over by himself, right?

Then, a group of people packed up their things and were about to leave.

When he walked to the door, Mu Yuan suddenly paused at his feet, and said after a while: "Brother Fan, I think this Zhang Kai'an and Jiang Lin have such a good relationship, and the two sides are fellow villagers far away from their homeland, so they must have very close contacts." Instead of going to Jiang Lin through technical means, it is better to guard Zhang Kai'an, I think there will definitely be a time when the two will meet. ”

"This is too unsafe, isn't it? What if they don't see each other for ten days and a half?" Fan Yitong didn't speak, but Qian Hongxian spoke first.

Mu Yuan pursed his lips and said, "I think, it's unlikely." ”

Fan Yitong hesitated for a moment and said, "Why don't you ...... Brother Yuan, you stay here for a while, and I'll contact Brother Qian and them first to see if I can make Jiang Lin's location information. If the conditions are not good, for example, in an area with a large number of personnel, we will squat at Zhang Kai'an first, and if the conditions are good, we will directly start with Jiang Lin. ”

Mu Yuan looked at Fan Yitong and said, "That's fine." ”

"Alright, I'll try to hurry up on my side. After Fan Yitong finished speaking, he and Qian Hongxian left in a hurry.

Mu Yuan shook his head helplessly.

Originally, I wanted to give Fan Yitong a chance to make meritorious contributions for the sake of Fan Yitong helping to pay for the meal, but the result was ...... This guy didn't get it.

Just at the stall where he had just gone out, Mu Yuan found that Zhang Kaian had dialed a phone call through Xiao Mao's field of vision, originally Mu Yuan didn't care much about this matter, but after listening to a few words, he found that the call was actually made to Jiang Lin.

Moreover, the content of the phone call was very gratifying, it turned out that Zhang Kaian invited Jiang Lin to come over for dinner......

It's not like stepping on iron shoes and finding nowhere to find them, so it takes no effort to get them.

It's a pity that Mu Yuan couldn't tell this situation directly, and in the end, he was the only one waiting here.

Fortunately, he is confident in his own strength, even if Jiang Lin is really a suspect, Zhang Kaian has the courage to help his friend attack the police, and Mu Yuan is sure to suppress these two people single-handedly.

It's only 8 o'clock in the evening, and Zhang Kai'an's call just now is about 9:30 in the evening, that is, after the guests in the store have basically left, and the place of dining is in this seafood city, according to Zhang Kai'an, he got a big grouper and asked Jiang Lin to come over to taste it together.

Although Mu Yuan is also quite greedy for groupers, he is even more greedy for Jiang Lin now......

There is still more than an hour, and the waiting process is undoubtedly very long.

The temperature in Haibo City is about the same as that in Xihua City, and at this time of year, the night is not very cold.

However, there is a clear difference between this side and Xihua City, and the wind blowing over always feels like a fishy smell of the sea - mainly because Mu Yuan's nose is too smart.

I stayed bored for a while, and I was really bored to death! This kind of experience was experienced the night I first came to work at the police station, and that time I stayed all night.

"Or ...... Let's try a 10-game draw? After all...... Good luck here. This idea suddenly popped out of Mu Yuan's mind, and it was a little uncontrollable.

I was going to give up Zhang Kai'an's line first, but I could hear the other party calling to invite Jiang Lin to come over for dinner, isn't it luck?

People are sometimes like this, when they want to do something, they can convince themselves by just finding a reason!

Mu Yuan is human, so he is no exception.

He would never think that he was just bored at this time, and wanted to draw cards to pass the time.

At that moment, Mu Yuan directly opened the system interface and directly entered the card drawing bar - for fear that he would change his mind if he moved slowly.

As soon as the thought moved, he pressed it directly on the ten consecutive draws, and then the cards flew all over the sky.

This picture is too familiar to be more familiar, and Mu Yuan has no mood to appreciate it - only when he flops the cards is the most exciting.

The first card was opened, and Mu Yuan's calm heart suddenly boiled.
