"Lixia, why are you here?" Qi Ye struggled to get up from the ground, and was about to walk towards Li Xia, when Xiaolong hurriedly stretched out his hand to stop him and asked, "What the hell is going on?" ”

"I called Officer Gu." Li Xia explained to Qi Ye, "Just now in the café, you said that you had guessed the identity of the murderer, and that it was all because of a mistake you made many years ago. You're going to find the killer and put an end to it yourself. I was worried that you would do something dangerous, so after separating from you, I immediately called Officer Gu. After speaking, Li Xia looked at Xiaolong with extremely complicated eyes and asked, "Long Simiao, is it you who killed my father?" ”

Listening to Li Xia's words, Xiaolong suddenly laughed twice and said, "Haha, is the murderer's daughter also qualified to question me this question?" Li Xia, if you hadn't given perjury to your father twelve years ago, the police wouldn't have ruled out Li Tianhua's suspicion of committing the crime so quickly. If they hadn't let Li Tianhua leave Longjing Village so quickly, as long as they had to investigate further, maybe the case would have been solved a long time ago. For so many years, you've been deceived by your dignified father. Do you think he's really a saint? Do you think he donated money to Project Hope and insisted on doing charity for many years because of kindness? I'm telling you, you're wrong. The reason why he lived a thrifty and simple life and sponsored children in poor mountainous areas to study was because he was ashamed of killing people......"

"Little Dragon!" Qiye pulled Xiaolong's arm, trying to stop him from saying continue. Xiaolong shook off Qiye's hand in disgust, and said viciously: "Let go, you bastard who shields criminals." I can see that you have hidden your secrets for so many years all for her. You think you're heroic and great, don't you? If it weren't for the fact that there were several murders in quick succession this time, would you be planning to take this secret to the grave? My dad and I are so blind that we would treat you, an ungrateful white-eyed wolf, as a family. I feel sick when I think about the days when I used to call you brothers. ”

Xiaolong's gaze scanned back and forth between Qiye and Li Xia a few times, and he sneered and said, "The murderer's son and the murderer's daughter, you two are really a perfect match!" ”

"Xiaolong ......" Qiye looked at his former best friend speechlessly, his face full of despair and pain. He knew that the matter had come to this point, and any explanation and apology would be hypocritical and meaningless in the eyes of the other party.

The conversation between several people was cold for a while, and Xiaolong didn't seem to bother to waste words with Qiye and Li Xia again. At this time, Gu Song, who had been standing aside and watching the excitement for a long time, suddenly spoke: "Have you all finished speaking?" Can I say a couple of words? ”

After waiting for a few seconds, seeing that no one responded, Gu Song said to Xiaolong: "Long Simiao, the police suspect that you are related to the recent series of murders that happened at the Normal University in R City, and now please follow me back to the city bureau for investigation." ”

"Investigate what?" Xiaolong's face changed, and he frowned very displeased and said, "Just because these two guys who are full of nonsense and harbor murderers think that I am a murderer, you suspect that I killed people?" ”

"Of course not." Gu Song smiled faintly, "I didn't doubt you because of their words. ”

"What's the reason for that?"

"Because of the motive for killing. You yourself don't deny that you are the person who hates Li Tianhua the most in the world, and you want to kill him to avenge your mother, right? ”

"So what?" Xiaolong shrugged his shoulders disappreciatively, "Officer Gu, don't forget, there have been several serial murders at the Normal University. Even if I have a motive to kill Li Tianhua, the other two victims can't fight me with eight rods, you have no reason to suspect that I am the perverted murderer you are looking for, right? ”

"Of course, how can a sane and sober person like you be a pervert."

"Then you ......"

"Seriously, at first glance, the cases at the Normal University really look a bit like the kind of perverted murder cases that make it difficult to figure out. But that's exactly the trick you use to confuse the police, isn't it? ”

"You, what did you say?" Xiao Long's face became even more ugly, and although the movements were very slight, Gu Song still saw his shoulders shake uncontrollably.

After Lai Tianhua was killed, the police focused their investigation on his relationships and deduced that the murderer's motive was revenge. Because of Qi Ye and Li Xia's lies, the police did not know that the murder case that occurred in Longjing Village in 2004 was related to Li Tianhua, so there was no way to know that you had a motive for the crime. On the surface, you and Li Tianhua are almost no people who have crossed paths in life, so the initial police investigation will definitely not fall on you.

A day and a half later, Liu Yiping, a retired teacher, was killed in her home. Based on the circumstances at the scene of the crime, the police deduced that the two cases were committed by the same murderer, and that the motive for the crime was the same revenge killing, and focused the investigation on the common relationship between the two victims. However, through investigation, the police found that for Mr. Liu, the possibility of revenge killing was almost non-existent, and there was no common connection between the two victims. As a result, the idea of perverted murder began to spread on campus. When the investigation stalled, some police officers began to suspect that the two cases were not committed by acquaintances.

"A few days later, Xin Yuan, a sophomore girl, was killed near the school's stadium, and although the police stepped up their time to investigate Xin Yuan's social connections and try to find a connection between the three victims, or a common feature in some way, the narrative of 'indiscriminate killings' intensified. At this point, the murderer has completely taken the police's investigative attention off the normal track, so that we are almost about to use psychological portraits to profile the characteristics of the suspect.

"However, Qiye's abnormal behavior made me think that there was something wrong with him from the beginning. Through the investigation of his and Li Tianhua's living backgrounds, I found that Longjing Village, where you lived together, does not seem to be a peaceful place. Each of your three families has had people die in an unusual way, and the unsolved case in 2004 in a rape field caught my attention. That day was Li Tianyu's death day, and Li Tianhua just took Li Xia back to Longjing Village to sweep the tomb. If it is not a coincidence that your mother was killed on that day, then her death may have something to do with Li Tianyu.

In 1991, Li Tianyu committed suicide by throwing himself into the river for unknown reasons. There are rumors in Longjing Village that Qiye's father killed Wang Zhiquan for Li Tianyu. Let's say that Li Tianyu was hurt by someone or some people back then, which led to her suicide. Then, the person who caused her suicide is likely to be retaliated against many years later, and perhaps Wang Zhiquan, who was killed by Qiye's father, is one of them. Just imagine, on the day of Li Tianyu's death in 2004, if someone would kill someone for Li Tianyu, it is very likely that this person is Li Tianhua. In other words, Li Tianhua is likely to be the murderer of Huatian's murder.

"Thinking of the delicate relationship between Qiye and Li Tianhua, and the scene when Qiye was sitting on the old locust tree at the entrance of the village at the time of the crime, overlooking the scene of the crime, I suspect that Qiye may have seen things that he shouldn't have seen back then. This can also explain why Qi Ye deliberately alienated Li Tianhua in the following years, why he was unwilling to ask Li Tianhua for help, and the suspicious behavior he showed on the day Li Tianhua was killed, because he didn't want to have contact with the murderer from the bottom of his heart.

"If Li Tianhua is the murderer of your mother, your suspicion of crime immediately rises to the top. The problem is that the police determine that the killer of the three murders at the Normal University is the same person, and you don't know the other two victims. That's when I started to wonder if your motive for killing the second victim was to mislead the police. At the same time, on the morning of Mr. Liu's murder, Qi Ye was detained by us in the criminal police team as a suspect in the murder of Li Tianhua, and the occurrence of the second case directly helped him eliminate the suspicion of committing the crime, which is also one of the purposes for you to kill Mr. Liu, right?

"If the second case was intended to mislead the police, then why did the third victim die? Or is it to mislead the investigation? I guess you're not so ruthless. Sure enough, through the surveillance video, we found that on the morning of Teacher Liu's murder, Xin Yuan accidentally bumped into the suspect near the family area, and may have seen the suspect's face. When the police announce that they are looking for a suspicious man wearing a baseball cap, dark tracksuit, and a school bag on one shoulder near the campus, you realize that the girl's presence is a threat to you, so you kill her in the same way in order to silence her.

"So to sum up, you committed a total of three crimes and killed three people at the Normal University, but the motive for each murder was different. The first case was a revenge killing, the second was a misleading investigation, and the third was a murder. If we keep investigating with vendetta as a motive, it will be fruitless, and shifting the investigative focus to strangers will undoubtedly waste a lot of our time. Long Simiao, you are really cunning, and you have taken great pains to avenge your mother. But Teacher Liu and Xin Yuan are innocent, how can you bear to kill defenseless old men and girls? Do you think you will be forgiven by your mother under the Nine Springs? ”

After listening to Gu Song's explanation, several people stood still like statues, and Xiaolong looked at Gu Song even more dumbfounded, as if he had been immobilized by magic. After a long time, he came to his senses, lit a cigarette with a slightly trembling hand, and said in surprise: "Officer Gu, your imagination is too rich, right?" It's a pity that all this ......."

Before Xiaolong could finish speaking, Gu Song received a call from Fan Cong. "Arrest someone, we found evidence of the crime at Long Simiao's house."
