"That's when you and Qiye met, right?"

"Sort of...... Li Xia still frowned, "Actually, I just said a few words to him at that time." I was a little scared to hear the local villagers mention some terrible things that happened in his house, so I ......"

"Are you afraid that he is also a madman who kills people without blinking?" Gu Song smiled bitterly, feeling aggrieved for Qi Ye in his heart. "As far as I know, your father has always had a good relationship with the Qi family, and I believe that when he went back to his hometown to visit the grave, he also visited Qiye's father by the way, right?"

"In fact, Qiye's father's grave stands right next to my aunt's tombstone. I still remember when I first went to visit the grave, I was very curious to ask my father who that person was, if he was a relative of our family, and jokingly asked him if that person was my uncle. But my father didn't tell me anything, only that the man was an old friend of his. Later, I learned that the tomb was buried with Qiye's father. ”

"They didn't have fate to become husband and wife in their lifetimes, but they can sleep together forever after death, I believe this ending is the best arrangement for them......," Gu Song muttered to himself, and the scene of two young figures chasing and playing in the sea of golden flowers couldn't help but come to mind.

A gentle and kind beautiful girl, a hot-blooded teenager with ideals, they have regarded each other as a lifelong dependence since childhood. Nothing in this world can separate them except life and death, and yet it turns out that even life and death cannot separate them.

Qi Tao followed in the footsteps of Li Tianyu, and the two of them finally fulfilled their original promise in the afterlife.

If Li Tianyu's suicide is related to Wang Zhiquan, Wang Zhiquan's killing by Qitao is related to Li Tianyu's suicide. Then, the case that happened on the day of Li Tianyu's death may be a continuation of those two events. Thinking of this, Gu Song immediately asked Li Xia, "Does the victim of that case have anything to do with your family?" ”

"No, I don't." Li Xia replied suspiciously. After thinking about it, he changed his words again, "Wait, I seem to have heard that the woman who was strangled to death at that time and my aunt were very good friends. There are also superstitious villagers who say that my aunt is too lonely to stay alone in the underworld, and she has to take her best friend down to be her companion. Officer Gu, why are you asking this? Does this have anything to do with the serial murders at the Normal University? ”

Gu Song didn't answer Li Xia's question, staring at the bowl of noodles in front of him that had turned cold. The truth is getting closer and closer, and the so-called "indiscriminate serial killing" is too deceptive. The police were locked in an investigative impasse because they could not find a motive for the crime and a link between the three victims.

In fact, the motive for the crime in each case is so obvious, but in three cases there are three different motives. The murderer went mad in order to achieve his goal. Now that the basic assumptions have been established, the next step is to look for evidence to prove the hypothesis.

Regarding the incident that happened in Longjing Village in 2004, some people are afraid that they lied to the police. Maybe Qiye didn't see anything, but saw something he shouldn't see. And the seemingly innocent girl in front of her also seemed to have deceived the police on something.

"Lixia, have you told me all the truth?" Gu Song stared at Li Xia's eyes seriously and seriously, as if he wanted to see her through.

Li Xia was taken aback by this sudden change, and couldn't help but shrink back. "Officer Gu, what do you mean by that? I've told you everything I can think of. ”

"Are you sure?"

"This ......," Li Xia said embarrassedly, "It's been so long, it's normal to have omissions, right?" ”

"Okay, that's it for now." Gu Song showed an unpredictable smile to Li Xia, "If you can think of anything else later, remember to contact me." After a pause, Gu Song added casually, "Whether you can catch your father's murderer depends on whether you are worthy of cooperating with our work." ”

"Of course I will fully cooperate with you......" Li Xia turned his head to look at the students who passed by from time to time, and more than once he had doubts about something in his heart.

Back at his mother's house, a greedy Jack immediately pounced on his rice bowl to eat. Mother didn't know that Gu Song had already had dinner in the cafeteria, so she specially made braised pork ribs for him. Gu Song didn't want to waste his mother's kindness, so he symbolically ate a few pieces and packed all the remaining ribs into the crisper box.

At eight o'clock in the evening, Gu Song came to the city bureau and found that many people had not returned home from work. He approached two colleagues who had been working in front of the computer to study campus surveillance and asked them if they had made any new discoveries.

Xiao Jia yawned and showed Gu Song a few screenshots of the video, and introduced weakly: "The suspicious man who followed Xin Yuan on campus last night was carrying a dark gray schoolbag on one shoulder, and the outer pocket of the schoolbag was missing a zipper buckle. On the morning of May 24, before and after Teacher Liu Yiping was killed, we also found a suspicious man in the surveillance. The man was dressed in sportswear, wore a baseball cap, and carried an identical bag on one shoulder. Based on the body shape of these two people and the way they walk, it can basically be judged that they are the same person. This person is suspected of committing a major crime, and colleagues in the investigation team continue to collect clues about his identity near the campus. ”

"This person is the suspicious man that Teacher Qin saw near the family area before and had contact with the victim, Teacher Liu, right?"

"Brother Cong has already confirmed with Teacher Qin, the old man is not very sure, but eight or nine is not far from ten, it should be him."

"What about when Li Tianhua was killed?" Gu Song listened with great interest, and dragged a chair to sit with them. "At noon that day, were there any suspects with similar features found near the administrative building?"

"Yes!" Xiao Li stretched his waist, readjusted his sitting posture, and took over the conversation, "Although he dodged the surveillance at the entrance of the administrative building and the elevator, there was a surveillance camera on the road north of the administrative building, and it seemed that it was that guy." The three cases were committed by the same murderer, and there must be no mistake here. ”

"What I want to know is ......," Gu Song continued to ask, "Did the first two victims, especially the third victim, Xin Yuan, also appear at the scene of the crime on the morning of Teacher Liu's murder?" ”

"Don't say it, I really made an unexpected discovery." Xiao Jia clicked on a video with some pride, and dragged the progress bar to a certain position to play it. In the video, Xin Yuan, a sophomore girl, was walking on the road with a few books in her arms, and collided with a suspicious man in a hurry, and the books fell to the ground. The man helped her pick up two of them, and after returning the books, he left without saying a word, keeping his head down and unable to see the facial features clearly during the whole process.

Gu Song noticed that the man had a flipping motion in the process of picking up the book, which seemed to confirm the girl's identity (many students have the habit of writing their class and name on the title page of the textbook).

After playing the video, Xiao Jia explained: "This video was taken by a surveillance probe near the family area. It is understood that Xin Yuan's aunt is a librarian at Normal University, and her family lives in Building No. 7 not far away. Xin Yuan would occasionally go to her aunt's house for dinner and stay overnight. On the morning of May 24, Xin Yuan happened to come out of her aunt's house and was about to go to the study hall to read in the morning, but she bumped into the suspect who had just finished the crime on the road. I guess that's why the killer chose her as his next target. ”

"Well, that's exactly what I want to see." Gu Song smiled and gave Xiao Jia a thumbs up, and the speculation in his heart was a little firmer.

Xiao Jia scratched his hair embarrassedly, feeling that this long and grueling work was quite worthwhile. As soon as the person relaxed, he suddenly felt very hungry, and hurriedly looked at the time and said, "Yo, it's so late, it's time to get some food and come back." ”

"Why, you haven't had dinner yet?" Gu Song asked in surprise.

"No, don't you want to fight for a while and see what other useful clues you can find."

Gu Song patted his head, "Look at my memory." Then he took out the things he had packed from home and put them on the table, and said to them, "These are the braised pork ribs that my mother made, you can try them." ”

A few people chatted while eating, and the atmosphere suddenly became relaxed.

More than 20 hours have passed since the third serial murder case was confirmed at 12 o'clock in the morning, and everyone is nervous, seizing all the time to find clues to solve the case, and there is hardly any rest. Gu Song only lay on the sofa in the office early in the morning and squinted for two hours, and then he has been running around.

Maybe it's because there have been too many things that have happened in the recent period, and Gu Song feels that the days have passed simply unprecedentedly long. Compared with other colleagues in the task force, the burden on his shoulders is not only the serial murder case at the Normal University.

Yu Jiannan is suspected of being involved in illegal organ trading, and is suspected of being killed by organ traffickers and dumping her body in the suburbs; Shen Hang and Miss M set up a game to escape, escaped from R City, and kidnapped Tian Rui as a bargaining chip; Zhong Xin and Xia Shi traveled to Liangshan to find a hiding place for the organization, but have not received positive feedback so far......

All these things are inseparable from him, but he can't spare any extra energy to contribute a meager strength now. The only thing that can be done is to end this serial murder case as soon as possible.

Gu Song clenched his fists, feeling that time was imminent.

"Hey, what kind of takeout did you order, it tastes so good." Fan Cong asked with a sniff as soon as he entered the office. Xiao Li pointed to the lunch box on the table and said, "It's not takeout, it's braised pork ribs made by Aunt Qiao herself, it's delicious." ”

"Really? I'm going to try it too. Fan Cong hurriedly came over, and he didn't know whether he had washed his hands or not, so he picked out a piece of meat from the box with the most.

Gu Song punched him in the chest, "Don't patronize and eat, I'll ask you to help me collect information about the murder case in Longjing Village, do you have any gains?" ”

Fan Cong gave him a blank look, "Damn, I've been busy all day, can you let me take a breath?" ”

Xiao Jia and Xiao Li looked at them inexplicably, feeling that their IQ was a little off. "What Longjing Village? What are you two investigating? ”

"The murderer's motive for killing." Gu Song replied succinctly, as if he didn't want to explain too much. So far, all the conclusions that have stayed in his mind are just his assumptions, and the first thing that aroused his suspicions was the panicked performance of Qi Ye at the scene of the crime when Li Tianhua was killed.

From the very beginning, Gu Song didn't believe that Qi Ye was "innocent". Although he didn't kill anyone, if he hadn't been secretive and hidden something from the police, the case wouldn't have become so complicated at all, and the extra sacrifices might have been avoided.

It's not good, Qiye is now beginning to suspect that the murderer is that person.
