After the meeting, Xia Shi put all the work in place, and wanted to have a good chat with Huo Yan about the progress of the investigation of clownfish. As soon as he said a few words, Gu Song suddenly broke into his office in a rage, grabbed his arm and walked outside.

"I'm sorry, Mr. Huo." Gu Song smiled apologetically at Huo Yan, "I have to borrow your boyfriend to use it now." ”

"What boyfriend?" Huo Yan didn't react for a while, looked at the two of them in surprise and asked, "What are you two doing here?" ”

"Go to the hospital, this guy is sick, I have to take him to the doctor."

"You're sick." Xia Shi glared at Gu Song viciously, broke free from his control, and said angrily, "You didn't see that I'm busy now, let's go another day." ”

"No way!" Gu Song categorically refused, "I've made an appointment with a doctor for you, you can go and see if you can die." ”

"But the case ......"

"If you come back from work, you won't be able to delay you for long." Gu Song said, pulled Xia Shi's arm again, thought about it and said to Huo Yan, "Teacher Huo, why don't we go together?" You two can continue to talk on the way. ”

Huo Yan followed the two of them into the car in a daze, and later learned that Xia Shi had stomach problems and was unwell. "You must be too tired from work and have an irregular life for a long time." Huo Yan remembered her time in the United States, and said with empathy, "I remember that when I first arrived in the United States, I was under a lot of pressure to study, my English was not very good, and I could barely cope with lectures and communication, but it was not so easy to read those esoteric books and materials.

"During that time, I stayed up almost every night to read, I had to drink strong coffee every night to refresh myself, and I didn't eat very regularly. Your current situation is similar to me at that time, not that I said you, you are still very young, you really have to take care of your body, otherwise you will regret it in the future. ”

"Alas, I understand what you said......" Xia Shi sighed helplessly, "There are too many cases recently, and I can't help it." If the world is peaceful and the bad guys are honestly staying at home, I don't want to waste all my good youth on those murderers and perverts. Forget it......" Xia Shi changed the topic with a wry smile, "Let's move on to clownfish, have you made any new discoveries in the past few days?" ”

"Hmm...... How to say it......" Faced with this problem, Huo Yan also seemed a little helpless. "In the past few days, I have run a lot of fish shops specializing in marine fish, and I have checked some relevant information, and I am about to become half a fish farming expert. I think it's most likely that the killer raised clownfish himself, so I also followed several forums and exchange groups to find clues. But this method of finding a needle in a haystack is too much work and requires a certain amount of luck. The main thing is ......"

Speaking of this, Huo Yan glanced at Xia Shi with an uneasy expression. The latter, sensing that the atmosphere was not right, asked suspiciously, "What is the main one?" ”

"I said you're going to have a stomachache again." Huo Yan smiled helplessly.

Xia Shi was so keen, and after looking at Huo Yan for a moment, she knew what she wanted to express. "It's okay, you don't have to be afraid of hitting me, I have now practiced the ability to be invincible, and I can accept the slap of fate anytime and anywhere. Moreover, if you want to say something, Gu Song has already said something similar to me this morning, and I am mentally prepared. ”

"Really?" Huo Yan shifted her gaze to Gu Song, who was concentrating on driving in the front row, "Do you also think we should expand our thinking and try to analyze this case from the perspective of serial murder?" ”

"Hey, I just made a small suggestion to Xia Shi and asked him to check if there had been a similar case before. In the unlikely event that a clownfish is truly a unique criminal marker for a serial killer, the direction and focus of our investigation will almost change. Once that situation occurs, re-delineating the scope of the suspect is Mr. Xiaohuo, your strength. Gu Song said and turned around and winked at Huo Yan.

At this moment, Xia Shi's mobile phone suddenly rang, and the car suddenly fell silent. Gu Song observed Xia Shi's reaction to listening to the phone from the rearview mirror in the car, and his heart gradually sank.

"Gu Song, turn around at the intersection in front, let's go back to the city bureau." Hanging up the phone, Xia Shi immediately ordered Gu Songdao.

"What's wrong?" Gu Song hurriedly changed lanes, and said in his heart that he would definitely not be able to go to the hospital today.

"Last night, there was a case in Jinshui County, and Team Zhao asked us to go over and see the situation."

"We're all mud bodhisattvas crossing the river now, and it's hard to protect ourselves, how can we have extra time to help them solve the case?"

"I definitely won't care about ordinary cases, but Team Zhao said that last night's case may be related to the serial murder case in R City, and he is not sure, so he called me over."

"You're saying that the 'Nail Killer' has appeared in Jinshui County?"

"I don't rule out this possibility, after all, Jinshui County is not far from R City, and it is not unusual for the murderer to escape there by any car."

"Who is the victim this time?" Huo Yan asked with concern.

"The victim, a 16-year-old high school student, was attacked by a murderer on his way back to his home from his classmates last night. Luckily, the child is still alive, and we'll find out when we get there. ”

Picking up Forensic Doctor Chen and Qi Ruonan at the gate of the Municipal Bureau, a group of five people drove to Jinshui County, which is more than 60 kilometers away from R City. Except for Huo Yan, the other four people have all cooperated with the local police to handle cases and are very familiar with the situation there.

At about 12 noon, the group arrived at the Jinshui County Criminal Police Brigade, and Captain Zhao Hongshan warmly greeted them. After arranging for everyone to have lunch at the guest house, several people divided up their work and began to work.

Xia Shi and Qi Ruonan followed Zhao Hongshan to the scene of last night's crime to investigate, and Gu Song, Huo Yan and Forensic Doctor Chen went to the County People's Hospital to find out about the situation of the victim and his family.

According to Zhao Hongshan, on October 5, that is, when it was almost 10 o'clock last night, Wu Kaifei, who studied at Jinshui County No. 4 Middle School, was attacked by a man in black on the way back to his home from his classmates, and was stabbed seven times by the murderer all over the body. Because the boy has played football since he was a child, his physical fitness is relatively good, and he resisted very fiercely when he was attacked, so none of the seven knives caused fatal injuries to the boy.

In addition, at the time of the crime, the police on patrol heard the boy's cry for help and arrived at the scene in time to scare away the murderer.

When he first received the report, Zhao Hongshan did not associate it with the case in R City, thinking that the reason for the attack was that the boy had been robbed on a secluded road, but after listening to the boy's description of the situation at the time of the crime, he believed that the murderer's purpose was not to rob, but more like revenge for personal grudges.

"As I was walking down the road, the man suddenly rushed out from behind and stabbed me with a knife. I was so scared that I asked him what he wanted to do, and if he wanted my phone and wallet, I could give them all, but he didn't say a word, just waved the knife in his hand, and wanted to kill me......" The boy woke up after surgery and said to Zhao Hongshan in the hospital room.

After learning about this situation, Zhao Hongshan immediately asked the boy's parents, teachers and classmates to inquire in detail about the boy's study, life and friends, to see if he had caused any enemies outside and was retaliated against.

But this possibility was quickly ruled out. The boy is sensible and obedient on weekdays, has excellent academic performance, never provokes those people in society, and is very simple in terms of feelings, and there is no trouble in love. The boy's parents are also self-conscious people, and they have never had a grudge against anyone, let alone get into trouble.

It is not robbery, it is not revenge injury, how should this case of violence against a minor be characterized?

Zhao Hongshan was a little confused for a while, and he didn't know how to carry out the next investigation. Thinking of the two vicious murder cases that happened in R City not long ago, the murderer's methods of crime were similar, and their county bureau also received a notice of assistance investigation, Zhao Hongshan felt that it was necessary to communicate with the police in R City about the situation, so he called Xia Shi.

The scene of the crime is not far from Wu Kaifei's home, but the location is relatively remote, lacking street lights and monitoring probes, and few people pass by at night. Wu Kaifei likes to take shortcuts from here every day when he comes home from school, and he has walked alone for several years, and he has never encountered hooligans or robbers, so he is naturally less vigilant against danger in his heart.

The path to the accident has been cordoned off by the police, and although the victim was lucky to save his life, the bloodstains left at the scene are still shocking.

"Team Zhao, at the time of the crime, were there any other witnesses besides those two patrol officers?" Xia Shi asked Zhao Hongshan.

Zhao Hongshan shook his head regretfully and said: "Actually, the two patrol officers didn't see anything clearly, when they heard the sound coming, that person had already run away. And the light was too dim at that time, and they only shook a vague figure, and one of the patrolmen chased him for a long time but did not catch up. ”

"Did the victim see what the killer looked like? Didn't the two of them fight in close quarters? ”

"The kid said he couldn't see clearly, and the assailant was wearing a hat and a mask, which was difficult to identify even during the day."

"Why did the murderer target Wu Kaifei?" Qi Ruonan stood at the place where the victim was assassinated, and said suspiciously and angrily, "The victim is just a minor student, how did he provoke the murderer and make the murderer kill him?" ”

"It's a very critical question." Xia Shi seriously recalled the two previous cases that happened in R City, and said thoughtfully, "If the murderer in this case is the same person as the previous murderer, then he must have had close contact with the victim somewhere not long before the crime." We now have to find out where the victim had been, who he had come into contact with, and who the killer might have been hiding among them. ”
