While Qin Lei was talking about the existing information that the police had, Jiang Chengyu also added some speculations that were more likely. And try to combine this information to get a more direct guess.

Liu Zigeng sat on the side and listened and ate the fruit plate, he knew that he couldn't help much. Chen Xiaohu and Zhang Junzhe listened to what they said, and nodded thoughtfully.

"Is it necessary to have surveillance in every corner to avoid such cases?" After Zhang Junzhe listened, he also thought that these crimes were too terrible, and the people around him might become victims one day, and said to Zhang Jingwei with a solemn face.

Zhang Jingwei lit a cigarette and said, "Even then, it is impossible to completely avoid it." ”

He can't give a definite answer, because the human heart is inherently complex and changeable, and the modus operandi of crime will change with the times. He has investigated too many cases over the years, all kinds of bizarre ways of death, and all kinds of unexpected criminal motives.

"However, the remaining range is still so large, it is not easy to find a person in this way." Chen Xiaohu looked at the information and gestured on the map and said, "It would be nice if we could narrow down the scope a bit." ”

Jiang Chengyu propped his chin in one hand while looking at the circled marks on the map, "Based on the speed of the prisoner's journey and the time to go to work at nine o'clock, if the prisoner goes to work directly, there will be a minimum speed and minimum stroke." If he had prepared a car in advance, then subtracting the walking distance from the nearby parking place to the scene of the crime, based on the speed at which he was driving, then he would have so much time and too many places to go. ”

When Jiang Chengyu said this, he paused, and without waiting for others to ask, he continued, "Everyone has their own personality characteristics and behavioral rules, and the characteristic of this murderer is punctuality. ”

Zhang Jingwei nodded when he listened, Zhang Junzhe didn't understand it very well, so he asked out loud: "How can you see that he is punctual?" ”

"Just like when you were in school, you must have found some very interesting people, and every time you go to class, you step on the point of the bell to enter the classroom." Jiang Chengyu made an analogy, but whenever Zhang Junzhe understood what the analogy had to do with this case, Chen Xiaohu reacted and said loudly: "I know!" If the prisoner does not show up for work on time, there is no need to drive the car to the parking lot. People who go to work on time every day will become a pattern of behavior. How do you explain the second case? ”

Jiang Chengyu said at this time: "Because the second case does not affect him at all to go home and sleep before going to work, it can also be speculated that his home and his company are nearby, and it is a place where he can quietly return on foot." ”

"Why did he choose to commit the crime so far away the first time, and then choose to commit the crime so close the second time?" Zhang Junzhe continued to ask.

"Although it is only speculation, it can be guessed that the murderer is not satisfied after killing a person, maybe it is for thrill seeking, or maybe the police have never found evidence, and he is not so careful the first time." Jiang Chengyu continued to organize the language, "Although there is no actual evidence to prove this, you see. Jiang Chengyu picked up a marker pen and circled the parking lot on the map.

In this new circle, the red circles that originally came out suddenly became much less. And because the time of death of the victim in the second case was between 2 and 3 o'clock in the morning, because the proofing time of the bar was 2 o'clock in the morning at the latest, and then the scene of the second case was used as the center of the circle, and the half-hour walking distance was used as the radius, a circle was drawn, so that the number of bars was directly reduced to one.

If you connect the bar to the murder scene of the first case, you can reach it on foot in two hours, you can reach it within an hour if you use a shared bicycle, and if you want to hide your tracks, it is not surprising that the murderer walked to that place and saw a car parked in that remote place.

After Jiang Chengyu finished speculating, he held his chin and said, "This is the most likely outcome, if this speculation is true, the focus should be here now." Jiang Chengyu pointed to a red circle on the map, and six words were written in the circle: "Devil's Roaring Bar".

"So what should we do?" Zhang Junzhe asked again.

"It's better for you young people to go, I won't go." Zhang Jingwei had already heard what Jiang Chengyu meant, and if he could find clues here, he would definitely go inside to understand the situation.

Zhang Jingwei had heard of that bar, a unique style of nightclub, which was full of some crazy young people, few people over forty years old went there, and he also liked Qin Lei, a newcomer, and he was very concerned about every case, so it was good for him to exercise. He looked at his son again, he also hoped that his son could be a police officer, but Zhang Junzhe preferred computers.

"Where are you going?" At this time, Liu Zigeng, who was bowing his head and playing with his mobile phone, asked.

"Haha, let's go to dinner first, then go to the bar and have a good time." Zhang Junzhe patted Liu Zigeng, who was sitting next to him, on the shoulder.

Liu Zigeng heard that when he went to the bar, his eyes could glow, from childhood to adulthood, Liu Qingtian did not allow him to go to these entertainment venues, only when the three of them were adults, Zhang Junzhe took them to a nightclub, shocking music, delicious drinks, and beautiful escort maids.

But when he got home, he was scolded by Liu Qingtian, Liu Qingtian's traditional concept is very strong, and he also has some principled prejudices against bars and nightclubs.

"Don't worry, I'll tell your dad that you're helping me solve the case, so let's have fun." Under Zhang Junzhe's gestured eyes, Zhang Jingwei spoke out, reassuring Liu Zigeng.

"Then I'm in for a treat tonight! Celebrate the Boss's victory today! Liu Zigeng said happily, and before Chen Xiaohu had time to cover his mouth, he continued to speak, "The boss played really well today, the martial arts movies I watched just now were not as strong as the boss's last punch!" ”

If you cover his mouth again, you can't hold it back.

Zhang Jingwei also raised his eyebrows and asked, "Where did you go today?" ”

Zhang Junzhe told him about this afternoon, and Zhang Jingwei knew what happened to them that afternoon.

"You played, and you lost?" Zhang Jingwei was a little displeased, he was the first martial arts academy in the police academy back then, and when he was young, he could beat the other side in hand-to-hand training with the special forces of the army.

"Well, the first time I played, I was a little ......nervous," Zhang Junzhe whispered, but there is a wall in his house dedicated to the trophies, medals and award certificates that his father won every time.

"Well, but these competitions are still too dangerous. These are all trivial things, and I'll find someone for you to practice more in the future. Zhang Jingwei said while drinking a cup of coffee, paused, and looked at Zhang Junzhe seriously, "Do you know how much mortgage our family owes?" ”

When Zhang Junzhe heard this, a question mark popped up in his mind, what is the matter with this mortgage? But come to think of it, he really didn't care about his family's finances.

"I don't know ......" Zhang Junzhe replied truthfully, waiting for Zhang Jingwei's next sentence.

"Two million!" Zhang Jingwei suddenly raised his tone, "Basically, everything that can be borrowed will be loaned out to buy you a house." People dare to bet on shares worth more than one billion, which shows that she must be confident that she can win, why not bet more? ”

When Zhang Junzhe heard this, he scratched his head in embarrassment, "Isn't that much money......?"

"I don't have any money to ask for me! He Wu Group wants to send money like this, I can't ask for it because of my identity, and no one can say anything if my son wants it! Zhang Jingwei was really surprised by the nine billion bets.

Every family has a scripture that is difficult to read, and Zhang Jingwei's difficulty is that the mortgage is not endless.

Although he became the captain of the criminal investigation team, he was an honest official, and he did not buy a few more houses before the house price rose, and now it takes more than 5 million to buy a house, and he doesn't know when he will be able to pay off so many mortgages with his salary.

In addition to his passion for his work, he also likes to look at the lottery in the hope that one day he will win the jackpot and not have to take on so many mortgages. He also fantasized about waiting for retirement, with a sum of money that would allow him to travel and walk everywhere. It's just that the mortgage has squeezed his pension, and the children still want to change their mother's car, and they don't have enough budget.

"Who would have thought of it......" Zhang Junzhe continued to be embarrassed, and Qin Lei and the others were already snickering beside him.

"Captain Zhang, these things, there will definitely be a ......continuation of the Wu family in the future," Jiang Chengyu said slowly at this time.

As soon as Zhang Jingwei heard it, he came to his senses: "If it weren't for my identity, I would have wanted to play, Xiao Jiang, just call me Uncle Zhang just like Zigeng and Xiaohu." Junzhe, you have to help me practice him more, it's a shame to be beaten down and lose. ”

"Uncle Zhang, I'll communicate more with Junzhe." Jiang Chengyu also agreed.

"That ......" Zhang Junzhe just wanted to interject and say, that is because others are experienced, and his own level is actually very good, he thinks that if he trains with Jiang Chengyu, it is one thing if he can beat him, and it is embarrassing to be knocked to the ground again.

"Don't say it yet, Xiao Jiang, since he recognized you as the eldest brother, if there is anything that an uncle can help, just ask. At least I can guarantee that the Wu side will not secretly make some small moves. "Although Zhang Jingwei is an upright official, he is not an old-fashioned person, they can prevent some older generations from interfering, but young people's affairs are best solved by young people, and it is impossible to always rely on the older generation to solve such things.

It's just that there are too few people on Liu Zigeng's side, although Liu Zigeng and Chen Xiaohu's families are also well-known figures, but Wu Feng is the same, and there are more people over there. He remembered Lin Xingsheng, the son of Lin Tianzheng of the Lin Group, who he met at the banquet, and it seemed that he hadn't heard the news of him joining any circle, if he could be pulled here, it might be of greater help to these kids.

But he just thinks about it, and it's not good to meddle in the juniors' friendships, and he has a good relationship with Liu Qingtian and Chen Xiaohu's father, Chen Lipeng, and they completely appreciate each other.

Friendship does not mean that the elders name and tell the younger generations who they want to make friends with, they can make friends with whom, that kind of friendship has more interests and less sincerity, and it will never be strong.
