"It's really inconvenient to have no car......" Jiang Chengyu thought in the taxi.

"Don't have a car? Inconvenience? Jiang Chengyu's head suddenly thought of these two words, and recalled the details of the parking lot.

"Master, please go here." Jiang Chengyu opened the map on his mobile phone and entered the location of the parking lot for the taxi master to see.

"Okay, I know the location!" The taxi driver didn't say much, and turned right at the previous intersection to take a shortcut.

At ten o'clock, the number of pedestrians on the road has begun to decrease, and the traffic on the return journey has become more.

Thirty minutes later, Jiang Chengyu came to the edge of the parking lot where the accident happened yesterday, and the parking lot began to reopen after the police left last night. He looked at the location of the surveillance equipment and saw that it was back to normal and could monitor the entire parking lot.

He imagines himself as the murderer at the time, and what he will do in order to get out of the scene as soon as possible. He walked behind the Chevrolet in the accident at the time, through the flower beds that surrounded the parking lot, and onto the empty pedestrian street.

Sure enough, the monitoring here will have some dead spots according to the angle of installation. Go to the left and go to the head, there is no monitoring blind spot here. Then he turned around and walked back, and at the last corner, he saw a man in sportswear, and the man also looked over.

Qin Lei didn't plan to come here again tomorrow to check, because he had a bad premonition and was worried that the murderer would continue to commit crimes, so it was best to find clues as soon as possible. He also discovered Jiang Chengyu, "Why is he here?" Curiously thought.

"Jiang Chengyu? It's been a long time! Qin Lei walked over and said hello to Jiang Chengyu.

"Senior Qin Lei, it's been a long time, what are you doing here?" Jiang Chengyu instantly found the impression of this person in his memory, and said lazily.

"You were also one of the witnesses in yesterday's case, and I believe you already know about it." Qin Lei said with a smile.

"Are you really a cop? Congratulations! Jiang Chengyu knew that Qin Lei had wanted to be a policeman since he was a child.

"Haha, yes, I was admitted to the police academy and the Criminal Investigation Department. By the way, I'm investigating this case, do you have any clues you can provide? Or rather, you found something and came here. Qin Lei raised his police officer card, but he knew this kid's ability, and looked into his eyes and said.

"Your presence here shows that the police have not been able to find out his escape route from the surveillance. In the same way, I was very interested in his escape route and how he escaped. Jiang Chengyu raised his hand and touched his chin and said.

"Did you find anything?" Qin Lei was a little interested, what could Jiang Chengyu guess.

"The murderer is very smart, but the person who does it will always leave useful information. There was also a murder this morning, and there is no surveillance video that can find clues, right? ”

"How do you know?" This made Qin Lei a little surprised.

"Because I was in the car passing by at the time, I took a cursory look, and the deployment and control of the monitoring equipment was similar to that here, and there would be some dead ends. What clues do the police have that you can tell me about? Jiang Chengyu also wanted to know where the police were now.

"There's nothing inconvenient, now the police haven't found any clues, the murderer is neither seeking money nor sex, and no one related to the deceased has a motive for committing the crime, so I am here to find clues." Qin Lei also briefly talked about the case on the side of the road, and took out the photos of the scene to show Jiang Chengyu.

"In the parking lot, have you found the scene of the crime?"

"I found it, next to the Xupu Bridge, on the vacant land on the edge of the Huangpu River, there is no monitoring, and I can't find any clues." Qin Lei also wanted to break his brain in the face of these things.

"That means that the murderer should be very familiar with the surrounding environment, and if the two cases are related, first find a route to monitor the existence of blind spots, and maybe find the destination of the murderer after fleeing the scene."

"Team Zhang said the same thing, so I'm looking for it now."

"I don't think there's any need to look for it, as long as the murderer is out of a certain range of the scene, let's take it here. Out of this pedestrian street, judging from his behavior, it is still very simple to blend into the crowd and go out, and it is impossible for you to compare so many people on the surveillance with any abnormality. Jiang Chengyu walked around the pedestrian street and found that as long as he got out of this area, the probability of finding the murderer in the video was infinitely close to zero.

"There's always a chance you'll find it. You've graduated, what do you do now? Qin Lei said helplessly.

"I work as an office assistant at Sanyang Pharmaceutical." Jiang Chengyu also sighed that if it hadn't happened to him, he might not have been able to get this job. It's no problem to be a bodyguard with his skills, but after all, there is a certain status gap with serious white-collar workers, which is really life-saving.

"That's a well-known pharmaceutical company in the country! Quite a salary, right? Qin Lei leaned over and said.

"Haha, the salary is average." Jiang Chengyu was sloppy and continued: "In this case, we can first look for the old residential buildings that have not been monitored nearby, and the case has not left any clues, and the murderer has not left a murder weapon, indicating that the murder weapon was taken away by the murderer." Looking at the appearance of the wound, the murder weapon should be a short dagger, like the ordinary clothes we wear can't be concealed, and it is impossible to take the subway with the murder weapon, the murderer can only choose to walk or take the bus, and there are only two places left for his destination, one is home, and the other is where he works. ”

After listening to Jiang Chengyu's analysis, Qin Lei also raised a few questions: "He chose the location of the crime when he killed people, if he was ready, then why didn't he throw away the murder weapon, and he couldn't check his fingerprints with gloves, right?" On the surveillance video of the entrance and exit of the parking lot, the top worn by the murderer is also casual sportswear. And, why go to an old residential building that isn't monitored? ”

"If the murder weapon is not thrown away, the first may be because the murder weapon has fingerprints on it, and the second may be that the murder weapon is very special and can leave guiding clues. As for dressing, wrap the murder weapon in a suit, put it under the back seat, and put it on when you go, whether it is put in the inner pocket of the suit or clipped to the belt. If I were a murderer, I wouldn't want my going out and going home to be recorded by the surveillance, because there would always be flaws. Jiang Chengyu explained to him briefly.

"Then you think it's a man in a suit?"

"It doesn't have to be a man, but it's definitely a black suit."

"It's been a day, he should have destroyed them all, right?"

"Well, it depends on whether he needs to keep this. But to know this, you must first find him, or find his hiding place. Jiang Chengyu can't infer whether these still exist or not when the evidence is insufficient.

"Ha, when you think about it, it seems a lot easier. However, for the sake of prudence, it is better to call up the monitoring of each community to take a look. Qin Lei's thinking was much clearer, but he still had questions: "Then what is his motive?" ”

"Well, this random crime, it's not that you want to prove that you're a genius, it's a human being who has been tempted by demons and has fallen." Jiang Chengyu has also learned about many random crime cases in murder cases, all of whom have some psychological defects, or have been harmed by something to take revenge on society, or want to express their dissatisfaction by killing people.

"Hehe, you're still the same, so smart! By the way, you can save my phone first. After Qin Lei finished speaking, he took out his mobile phone and dialed a number.

After a while, Jiang Chengyu's mobile phone rang. Jiang Chengyu understood, this Qin Lei should have read the contact information he left in the case materials.

"I saw it on the case file, and I was quite surprised when I confirmed that it was you, so I saved it, thinking about when I would be able to use it, but I didn't expect it to be so fast. Is that cute girl your girlfriend? Qin Lei inevitably wanted to gossip, after all, Lin Yuchen's appearance was very outstanding.

"That's.,It's just a school girl.,Now I'm working as an assistant.,I happened to meet that day.。 Jiang Chengyu said casually, he didn't want to listen to this person's gossip, according to his curiosity, he would definitely get to the bottom of it, from acquaintance to emotion, how could he know such a beautiful girl.

"Oh? Is it? Qin Lei obviously didn't believe it, he looked at his phone and said, "It's half past ten, do you have a car?" ”

"Not yet, by taxi."

"Then where is your home, I'll send you?" Qin Lei rarely saw his old friend, and although he wanted to have two drinks with him, he also knew that it was too late today.

"Then I'll trouble you, Senior Qin Lei." Jiang Chengyu did not refuse.

"Haha, don't bother, I have a problem here in the future and I want you to help analyze and analyze, I know that you kid has a smart brain." Qin Lei is also very satisfied with today's results, at least he has a direction, so that he will not watch those boring surveillance videos all day long, and he has to talk to Team Zhang about this situation.

The life of Shangdu, in the eyes of some people, has really begun at this time, and this is also a city that never sleeps in the eyes of many people, of course, this city that never sleeps is also a gold cave.

……

"Brother! You're back, where did you go on a date, and when will you bring your sister-in-law back? Lin Yuchen saw Lin Xingping open the door and came back, and joked happily.

"Dad, I'm back. Sister, my brother is not as capable as you, and he doesn't even have a girlfriend yet. Lin Xingping first said hello to Lin Tianhao, and then the corners of his mouth curled up and gave Lin Yuchen back.

"Brother!" Lin Yuchen reacted instantly, and his face was a little hot.

"Xingping, you come with me." Lin Tianhao called Lin Xingping, who had just entered the room, to stop and go to the study together.

"Okay, Dad."

"Really, you're going to whisper again, mysterious." Lin Yuchen grunted.

"Haha, it's a men's topic, do you want to listen to it?" Lin Tianhao touched Lin Yuchen's head and said with a smile.

"No, you go, go." Lin Yuchen was watching the TV series, of course he didn't have time to listen to their men's topic.
