The suspicions of the case were confirmed the next day.

"The murderer is likely to be the same person." As soon as he walked into the office, Jiang Ruiheng first gave a conclusion. He threw several autopsy photos on the table and said, "If you look at the wounds of these two deceased, they have one thing in common, which is that the wound area on the side of the blade is larger than on the back side of the knife, and it is obviously valgus. This wound was caused by the murderer twisting the handle of the knife after stabbing it. ”

"Twist the handle?" Shen Yan raised his eyes, "In order to make the victim lose blood faster?" ”

"It should be." Jiang Ruiheng nodded. "The depth of the wounds of the two deceased is shallower than in ordinary homicide cases, indicating that the murderer's hands are not strong. It was probably because of this that he had to twist the handle of the knife to widen the wound area and speed up the bloodletting to ensure that the victim would die. Therefore, it is very likely that the murderer was a relatively thin man, or the murderer himself was not left-handed, but for some reason he injured his right hand, so he was forced to switch to his left hand. ”

Hearing the last sentence, Shen Yan frowned.

After Jiang Ruiheng finished speaking, he looked at Cheng Jinsong sitting next to him, and asked, "What did you find over there?" ”

"The murderer was very careful, and he wiped all the places without leaving fingerprints. Jiayu found several pieces of dander on the towel where the murderer wiped the bloodstains, and was testing the DNA to see if it was the deceased or the murderer's. But the towel was a public good. Therefore, even if the dander is not the murderer's, it is difficult to guarantee that it is. ”

"Is there blood on anyone's bathrobe?"

"I haven't seen it yet. There are nearly 100 men's public bathrobes at that bathhouse, and it also sells new bathrobes. We saw it yesterday when we collected the bathrobes, and no one had blood splatters on their clothes. Now everyone is testing these bathrobes to see if they can find anything. But I don't think you should get your hopes up. ”

"That's just as well. If it were me, I would have taken the bathrobe with me. Jiang Ruiheng said, "It's too dangerous to stay." ”

"I also don't think a murderer would make that kind of mistake." Shen Yan said. "Now it is almost certain that the two dead were killed by the same murderer, and we can determine the direction of the investigation."

The three of them were talking here, but there was a sudden knock on the door, Cheng Haiyang pushed the door open and greeted eagerly: "Boss, Brother Jin, come out and take a look, Kaizi has a big discovery!" ”

The three of them immediately got up and went to the big office. As soon as Qin Kai saw the three of them coming out, he immediately beckoned: "Boss, come and take a look!" ”

"What did you find?"

"Didn't Rui Heng just say that these two dead people might have been killed by the same person? So I looked up these two people on the Internet, and I found such a piece of news! ”

On the screen was a piece of news from last month, titled "Architecture University Student Hit and Killed, Hit-and-Run Vehicle". Looking down, the first paragraph reads: "At about 22 o'clock on the 16th of this month (December), a male student from the University of Architecture and Construction in our city was hit by a speeding truck at the school gate...... After rescue efforts failed, the student died in the early morning of yesterday (17th). ”

Shen Yan pulled the mouse to look down: "When the reporter rushed to the hospital, the student's parents cried bitterly in the ward. According to the student's classmates and teachers, the deceased Li was from a rural area, his family was poor, and his parents were local farmers. Guo himself is excellent in character and learning, and has won many school scholarships......"

"Boss, look here," Qin Kai pointed to one of the paragraphs, "According to pedestrians near the University of Architecture and Architecture, the street lights on this road in front of the University of Architecture have not been lit, and the whole road is very dark at night. Nearby residents said that the street lights on this section of the road have been off for more than two months, but no one has come to repair them. Some residents have called the urban renewal bureau street lamp to report for repairs, but have never received a reply, and many citizens have said that dark roads are one of the important reasons for the frequent car accidents here......"

As soon as he finished reading this paragraph, Shen Yan already understood what Qin Kai meant. He looked up: "Liyuan, you call the Chengdong Traffic Police Team and ask them how the case is now, and where the deceased's parents are now." ”

Fang Liyuan nodded and went to the table next to him to make a call.

Shen Yan picked up the mouse and continued to browse the webpage. Several photos of the crash were given on another portal, one of which was from the scene of the crime, another close-up of a street lamp and the last one was a photo of the family of the deceased taken in the hospital.

Looking at these photos, Shen Yan frowned.

"What's wrong?" Cheng Jinsong asked.

"I just visited this place a while ago." Shen Yan pointed to the first photo and said.

"Have you been?" Cheng Jinsong was surprised, "When did you go?" ”

"When investigating the planing case. The building materials factory of the third deceased, Zhao Guangjian, was on this road. ”

"Ahh Cheng Haiyang shouted on the side, "Why do I say it looks so familiar!" ”

Cheng Jinsong immediately understood the reason why Shen Yan frowned: "I remember that you told Wang Ju at the beginning that Zhao Guangjian may not have been killed by Li Hongwei, right?" ”

"Yes, Li Hongwei himself didn't admit it, and the target of the murder and the time of the crime didn't match."

"So, do you suspect that Zhao Guangjian's death has nothing to do with the planer, but with this case?"

"I don't dare to say it now, but the last time I went to Zhao Guangjian's wife to find out about the situation, I noticed that Zhao Guangjian's cars from their building materials factory all passed by that road, and the speed was also very fast." Shen Yan pondered and said, "If the accident is really a big truck......

As he was talking, Fang Liyuan had already put down the phone: "The Chengdong Traffic Police Force said that the deceased's name is Guo Xu, 22 years old, a junior at the University of Architecture. His father's name is Guo Zhicheng and his mother's name is Wang Xuemei, and they are farmers in the countryside of the city. It is said that Guo Zhicheng's health is not very good, it seems that he has some lung problems, he can't do heavy work, and his family's income basically depends on his daughter-in-law. Guo Xu's accident hit their husband and wife very hard, and the driver who caused the accident has not been caught so far, Guo Zhicheng and his wife have gone to the traffic team several times to make trouble. ”

Weak and motivated-several people glanced at each other-this Guo Zhicheng sounded really suspicious.

Shen Yan asked: "Do they have any contact information about Guo Zhicheng?" ”

"Yes, the police department gave me a mobile phone number."

"Call him now!"

Fang Liyuan immediately dialed Guo Zhicheng's phone, but what came from there was a system prompt that the mobile phone was shut down in arrears. Shen Yan immediately decided to go to the traffic team of Chengdong District.

Shen Yan was received by Han Xing, the deputy captain of the Chengdong Traffic Team, who introduced the situation while letting everyone into the house: "This Guo Zhicheng has been to our traffic team several times, and every time he is very emotional, and he shouts that our traffic team does not do anything. In fact, we were also very helpless, when the car accident happened, it was already more than ten o'clock in the evening, it was very dark, there were few pedestrians on the road, and there were no street lights, no one could see what kind of car it was. We asked the neighborhood for days, but we couldn't find any witnesses. However, Guo Zhicheng and his family felt that we were inactive, and they even went to the gate of the district government to make trouble, which gave us a special headache...... To be honest, we can also understand the mood of being a parent, it is easy to raise my son so big, and I am about to graduate from college, and this kind of thing happens. But if it happens, we can't help it. ”

"Then Guo Zhicheng has shown dissatisfaction with the city construction?"

Han Xing recalled and nodded: "Guo Zhicheng asked the street lights at the entrance of the school to ask what was not lit. We also explained to him, saying that it was not our responsibility, and that the city construction was responsible for repairing it. As for whether he went to Chengjian to make trouble, we don't know. Actually, I won't tell you anything, don't talk about them, it's quite breathtaking for our traffic team to mention this matter. The place of the University of Architecture is right on the highway crossing, and there are many cars at the door, and there is no light. There had been an accident in that place two years ago, and it was only after that accident that the street lights were installed. As a result, this time they repaired the road, and the underground pipeline was dug up again, and the lights were not lit again. We have already reacted to the urban construction side, but if the urban construction is not repaired, we have no choice...... Every time something happens, the first thing the people to blame must be our traffic police force, but what can we do? We can't send people there 24 hours a day, can we?! Captain Shen, you may not know that our team of more than 100 traffic police officers is responsible for such a large area of traffic in the whole district, and everyone often works overtime, and they can't take two days off a month on average......"

Watching Han Xing vomit bitterness, Shen Yan nodded in understanding, and then interrupted without a trace: "Then Captain Han, do you know where Guo Zhicheng has been recently?" ”

"Lately?" Han Xing recalled and said, "Guo Zhicheng really hasn't been here for a week, and we all thought he had returned to his hometown." What's wrong? ”

"We have a case that may be related to him," Shen Yan briefly introduced the case, and then said, "This person is very qualified in all aspects, so we suspect that he is likely to be the murderer we are looking for." It's just that the mobile phone number you gave us has been shut down in arrears, so we want to ask if you have any other contact information for him, or if you know where he lives. ”

"There should be in this file, you wait!" After Han Xing finished speaking, he ran out quickly. Soon, he walked back with a folder. "There's an address of his house, and a temporary address of his home in the city at the time, and you can go and look it up."

"Okay, thank you!" Shen Yan took it, then remembered something, and asked: "By the way, Captain Han, Guo Xu's case, can you roughly determine what kind of car caused the accident?" ”

"It's supposed to be a sedan."

"Sedans? Shen Yan was a little surprised, "It's not a big truck?" ”

"It's not. The part where the deceased was hit was low, and it certainly could not have been caused by a large truck. What's wrong? ”

"Nothing." Shen Yan shook his head, but there was a trace of doubt in his heart—could it be that he was wrong? ……

After getting the address from the traffic team, Shen Yan immediately took someone to look for it, but when they arrived at the small hotel, everyone learned that Guo Zhicheng and his wife had checked out and left ten days ago. Seeing that it was getting late, Shen Yan asked everyone to close the team and set off for Guo Zhicheng's house tomorrow morning.

Several people dispersed, and Shen Yan was also preparing to go home. Just then, the phone rang.

It's Cheng Jinsong.

Shen Yan picked up the phone: "Hey? ”

"How's it going?" Cheng Jinsong asked.

"I didn't find it, Guo Zhicheng no longer lives in the hotel, I plan to take someone to his hometown tomorrow."

"Hmm. Have you called it a day now? ”

"I'm getting ready to go home. What about you? ”

"I'm already at home and I'm doing my homework."

"Doing homework?" Shen Yan was stunned, "What homework are you writing?" ”

"It's the meeting when I was on a business trip some time ago, and the Wang Bureau said that I couldn't go abroad at public expense in vain, so I had to make a report to the police station to introduce the advanced experience of foreign countries."

Listening to Cheng Jinsong's slightly complaining voice, Shen Yan couldn't help laughing: "It's good." When will it be spoken? ”

"The day after tomorrow, the system has a summary annual meeting, and all departments will send people to it." Cheng Jinsong added, "Maybe you have to go too." ”

"Okay," Shen Yan laughed, "Then I'm going to study hard with Team Leader Cheng." ”

"Well, okay, I've taken your brother anyway, and I'm not missing you. Anyway, one sheep is driven and two sheep are released. Cheng Jinsong replied jokingly, and then he spoke again: "Anyway, it's not too early, you hurry home for dinner, be careful that you have a stomach ache after a while." ”

"Yes, master......" Shen Yan replied in a long voice, with a hint of naughtiness in his smiling voice.

"Haha, good." Cheng Jinsong laughed out loud, "Okay, you're going home soon, I'm going to continue to report it." ”
