From the third case alone, Zhang Chao and Lin Chang both have certain criminal suspicions, but judging from the two previous murders, neither of them seems to have a reason to kill Li Tianhua and Liu Yiping.

The results of the investigation showed that Zhang Chao and Lin Chang had no relationship with the victims of the previous two cases, except that they were both from the Normal University, their lives had no intersection and they had no motive for committing the crime at all.

Some people questioned it, saying that the third case was likely to be committed by someone who took advantage of the chaos to imitate the crime, and the murderer must be an acquaintance of Xin Yuan's side. Although the police have never released the details of the first two cases, there are always well-informed people who can find out the inside story from various sources and use the same methods to commit crimes.

As a result, the opinions of the members of the task force were divided. In order to make the work fully carried out, Director Xia sent a group of people to focus on investigating Xin Yuan's social relations and finding out the suspects with criminal motives. In addition, they have to carry out a lot of work on the campus, looking for relevant witnesses, and finding out the identity of the suspicious man who followed Xin Yuan as soon as possible.

Whether this case is a continuation of a serial murder case or someone imitates the crime, the murderer has extended the clutches of evil to these energetic college students. While making every effort to solve the case and arrest the murderer, they must strengthen the security of the campus to prevent the murder from happening again.

After the meeting, Director Xia deliberately left Gu Song behind, wanting to ask him what he thought about the three cases.

In fact, after a few days of thinking, coupled with the influence of some rumors, Director Xia has begun to suspect that these cases are not revenge crimes committed by acquaintances, but more inclined to kill the murderer of the three victims is a serial killer with abnormal psychology.

Facing Director Xia's expectant gaze, Gu Song's mind was in chaos. Although the murders happened one after another, he always felt that the key to solving the problem still lay with Li Tianhua. He knew that the opinions he gave would affect Director Xia's judgment to a certain extent, so he didn't dare to say his conclusions before thinking about it clearly.

After being silent for a long time, Gu Song said to Director Xia with a sad face: "I'm sorry, I haven't figured out what the internal connection between these cases is, and I still need to continue to investigate and understand many situations." ”

Director Xia silently took a few puffs of cigarette and sighed helplessly: "The social impact of these cases is really bad. The vice principal, teachers, and students were killed one after another, and what was originally a pure land for children to grow up and receive education turned into a murderer's paradise in just a few days. If the new round of investigation still fails to make effective progress, we can only ask criminal psychology experts from the provincial department to help solve these cases. ”

"Well, it's really desperate...... Gu Song responded to Director Xia's words, but he didn't mean to admit defeat at all.

After ending the short conversation and coming to the corridor, Fan Cong immediately came up and asked teasingly, "Detective Gu, is the director putting pressure on you again?" ”

Gu Song shook his head with a wry smile, didn't answer, glanced at the time and said, "Let's go, let's go have lunch first, I'm so hungry that my stomach hurts." ”

Halfway through, the two met Qi Ruonan, who was about to go to the cafeteria to eat. Gu Song had already put last night's episode behind him, and greeted Ruonan with a smile and said, "Senior sister, let's go to dinner together." ”

Qi Ruonan looked at Gu Song with strange eyes, and then glanced at Fan Cong who was standing next to him, and after a few seconds, he said lukewarmly: "I won't use it as a light bulb for you." ”

"Huh? What are you talking about? Gu Song didn't react for a while, Fan Cong hurriedly explained: "Ruonan, please don't make trouble." It was just a misunderstanding last night, and I was wiping the dirt off his face. ”

"Really?" Qi Ruonan pouted, as if he was still entangled in something. "But I've heard you say that it's not good for me to see anything...... Anyway, you two must be hiding something nasty from me. ”

"This ......" Fan Cong suddenly didn't know how to round this matter, and was thinking about whether to emphasize sex and ignore friends once, when he heard Gu Song say to Ruonan in a surrendering tone: "Okay, since I can't hide it anymore, then I'll tell you the truth." ”

Seeing Gu Song look like he was about to confess his adultery, Fan Cong couldn't help but swallow nervously.

"Ruonan, your birthday is just a week away." Gu Song explained in style, "Fan Cong has carefully prepared a birthday gift for you, and asked me when it would be more appropriate to give it to you." I told him to hide his things and not let them be seen by you in advance, otherwise it would be boring, right? After speaking, he touched Fan Cong with his elbow, and the latter immediately took over the conversation, nodded again and again: "That's right, that's it." ”

The atmosphere was stalemate for a moment, and Qi Ruonan suddenly laughed and said, "Actually, I'm joking with you, but I'm still very happy to know that there are gifts for my birthday." She looked at Fan Cong and said happily and movingly, "Thank you." ”

Fan Cong scratched his hair, and replied embarrassedly, "You're welcome", and said that he had to prepare a generous gift for Ruonan quickly.

At around five o'clock in the afternoon, Fan Cong received a message from Xiao Meng, saying that Qi Ye went to the Affiliated Hospital of R City University of Traditional Chinese Medicine alone, and found that Long Simiao's father had been transferred to that hospital for treatment. After receiving this news, Gu Song immediately put down the work at hand and prepared to go to the hospital to talk to Long Simiao's father about the things of the year.

Through Fan Cong's investigation, Gu Song learned that a lot of "strange things" did happen in the small village where Qiye and Long Simiao lived. In addition to Li Tianhua's sister Li Tianyu's bizarre suicide and Qi Ye's father Qi Tao went crazy to kill, he also found that there was an unsolved murder case in that small village.

On the afternoon of March 24, 2004, a woman in Longjing Village, Guangxi Province, was strangled to death in a rape field, and the killer did not leave any evidence at the crime scene. The police carefully investigated everyone in the village at that time, and conducted investigations from various aspects such as the motive for committing the crime, the time of committing the crime, and the ability to commit the crime, and almost ruled out the suspicion of committing the crime. The case was unsolved, the murderer fled, and twelve years passed in a flash.

The reason why Gu Song was so interested in that murder case was not only because the murderer was not caught, but because the victim of that case was Long Simiao's mother, Qin Liman.

I don't know if it's a coincidence, but three people who are closely related to the serial murder case of the Normal University, Li Tianhua (the victim of the case), Qi Ye (the original suspect), Long Simiao (the suspect's best friend), and everyone's family has had terrible and unfortunate things. From 1991 to 2016, in the past 25 years, five lives have passed away in an abnormal way.

In 1991, Li Tianyu committed suicide by throwing himself into the river.

In 1995, Qi Tao brutally murdered Wang Zhiquan, a man from the same village. In the same year, Qi Tao was sentenced to death for intentional homicide.

In 2004, Qin Liman was killed.

In 2016, Li Tianhua was killed.

Although Gu Song didn't know what the relationship between these families was like, it was conceivable that what happened to them should be inextricably linked. It's just that those long-ago events have anything to do with the serial murder case that happened now at R City Normal University?

In the single ward on the sixth floor of the inpatient department, Qi Ye was sitting in front of the hospital bed chatting with Uncle Long. The transplant is scheduled for the morning after tomorrow, and the patient will need to do some basic physical examinations before the surgery.

When Gu Song knocked on the door and walked into the ward, Qi Ye looked very surprised. Because Xiaolong found a matching kidney source for Uncle Long through unconventional channels, when the police asked him about the whereabouts of Xiaolong and Uncle Long, he didn't dare to tell the police the truth. One is that they are worried that what they do will be prosecuted by the law, and the other is that they are afraid that it will affect the normal operation of the operation.

They finally seized this once-in-a-lifetime opportunity, and if something went wrong in the middle, delaying the operation, or even causing the operation to be canceled, their previous efforts would be in vain.

In order to repay the loan shark, Xiaolong is busy outside all day long in order to raise money. At this time, the only thing he could do was to accompany Uncle Long in the hospital to ensure that the operation could go smoothly as planned.

"Officer Gu......" Qi Ye slowly stood up, looking at Gu Song with a complicated expression, with a hint of pleading in his eyes. Gu Song smiled at him and comforted him, "Don't worry, I don't want to care about what you're doing now." After speaking, he looked at the middle-aged man who was sitting on the hospital bed, "I'm here to find Uncle Long today." ”

"Looking for me?" Uncle Long didn't know that his godson Qiye had been questioned by the police as a key suspect in the murder of Li Tianhua, and he didn't know that Qiye had a friend who was a policeman. He looked at Gu Song in surprise and asked suspiciously, "Are you a policeman?" ”

"Hello, I'm from the Criminal Police Detachment of R City." Gu Song showed his ID to Uncle Long, afraid that the other party would misunderstand his intentions, so he hurriedly explained, "Don't be nervous, I just want to ask you about Longjing Village today." ”

Hearing this, Uncle Long breathed a sigh of relief, smiled bitterly and said, "I thought that I wouldn't be able to do the surgery the day after tomorrow." ”

Gu Song was a little embarrassed, but he had no intention of pursuing their illegal organ trading. Anyway, the people in the F branch are doing their best to track down those black intermediaries and organ traffickers, looking for the murderer of Yu Jianan, just turn around and say hello to Liu Yang.

As a police officer, Gu Song certainly hopes that the illegal trade in organs will be banned. Although many patients prolong their lives in this way, living-donor organ transplants come at the cost of harming another person's health. Thinking about the young people who sold their kidneys for tens of thousands of dollars, they have to endure the pain of deterioration and physical exhaustion in the next life, such behavior is really not worth advocating.

Looking at Uncle Long in front of him, Gu Song didn't know if he hoped that this operation would go smoothly. He hopes that Uncle Long can live well, but he also doesn't want organ donors, especially young and strong young men like Yu Jianan, to sacrifice their health for a lifetime. But......

Gu Song couldn't help but think of Tian Rui a few months ago. If Tian Jiaxuan failed to succeed in matching, Tian Rui's life was in danger, and there was only one road left in front of him, would he still care about his identity and those so-called ethics and morals?

Maybe in order to save the most important person in his life, his choice will be the same as Qi Ye and Uncle Long. Thinking like this, he suddenly felt very conflicted in his heart.
