Pushing open an unlocked iron door, the two men went to the roof of the school building. Less than 20 meters to the east is the scene of the crime. At this time, two surveyors were still there to continue to search for valuable traces.

It was there that the fate of the two flower girls changed dramatically in an instant, one died and the other was arrested unjustly. And the real culprit, who carefully planned this case, may be hiding somewhere and secretly peeking at everything, reminiscing about his masterpiece and snickering.

In order to learn more about the case, grasp more clues, and help Mu Zi clear his grievances as soon as possible, while Gu Song was checking the situation around the stairwell and computer room protruding from the roof, Xia Shi immediately walked towards the edge of the rooftop.

Both surveyors were unfamiliar faces. Seeing that someone suddenly broke into the scene of the crime and interfered with their work, one of the bespectacled trace examiners said to Xia Shi very unhappily: "Didn't you see the cordon? A murder has just happened here, and unrelated personnel should leave quickly and do not destroy the traces of the scene. ”

Xia Shiqiang squeezed out a trace of an embarrassed smile, took out his documents and said to the two: "Hello, I am Xia Shi from the Criminal Police Detachment of the Municipal Bureau, and I want to ask you about the situation." ”

The two investigators looked at each other for a moment, and the man with glasses asked suspiciously, "You took over this case?" ”

"That's the case...... Xia Shi explained his intention to the other party, and seeing that the other party still put on an expression that was not willing to cooperate, he specially added that Director Xia personally asked him to come, after all, the case involved the director's son.

After learning about this situation, the other party's attitude obviously improved a lot. Another trace examiner, who was about the same age as Xia Shi, pointed to a place on the edge of the roof and said, "Oh, this is where the victim was attacked by the murderer and fell to his death." The murder weapon was supposed to be this bloody stone. ”

Xia Shi glanced at the stone in the evidence bag, frowned slightly, and asked curiously, "Where did this stone come from?" ”

"Over there." The trace inspector pointed in the direction of the stairwell and said, "There's a pile of rubble like this under the wall over there, probably left over from repairing something." The murderer picked up a piece from it and threw the stone on the edge of the rooftop after committing the crime. ”

"But then it's not the murder of passion that you speculated before." Xia Shi immediately pointed out the suspicion, "You see that the stairwell is at least fifteen meters away from here, if the two people have an argument in the course of talking, and the murderer attacks the victim with a stone and pushes her off the edge of the rooftop, then the murderer does not have time to pick up the stone in the middle of the way." In other words, when the murderer came out of the stairwell, he already had the stone in his hand. So the murderer didn't come to the rooftop to make an appointment at all, but came directly for the purpose of killing. ”

"Even if so, there's nothing unreasonable." The marker wearing glasses said disapprehantly, "It is understood that the suspect Mu Zi has a long-standing grudge with the victim, and he has long had the idea of killing the victim. Tonight's meeting was just a chance for Muzi to kill, so it wasn't surprising that she had been prepared. ”

"Then why didn't she destroy the evidence and leave after she killed someone, why did she call the police?"

"The reason is simple, she regretted it after killing someone. Haven't many murderers shown remorse after committing crimes? ”

"If that's what you said, isn't she calling the police just to turn herself in? Why did she keep saying that she had been framed after the police came? ”

"This ......" summer time problem caught the spectacled trace examiner a little off guard. He pondered for a few seconds, shrugged his shoulders boringly, and said, "I can't fathom the psychology of a murderer. Maybe she's just playing a trick with the police, or maybe she's got some luck......"

Hearing this, Xia Shi glanced at the other party in disgust. With his understanding of Muzi, such a thing was absolutely impossible. Although he wanted to scold and reason with the other party, thinking of his identity, he still tried his best to control the anger in his heart and asked another trace examiner, "Can this stone extract fingerprints?" ”

"It's a little bit difficult." The trace inspector replied truthfully, "The surface of this stone is too rough and the shape is very irregular, so we have to take it back and try it." In addition...... he continued, "we also found the victim's mobile phone on the edge of the rooftop. There are fresh bump marks on the phone, which should have been dropped on the rooftop when the victim was attacked by the murderer. ”

"What else have you discovered?"

"There are also a bunch of cigarette butts that I don't know if they have anything to do with this case." The bespectacled trace examiner was unwilling to be lonely, "I heard that some students sneak up to the rooftop to smoke. According to the victim's good friend, because the study pressure was too high and the parents' expectations were too high, the victim also had the habit of coming to the rooftop to smoke to relieve stress. To be on the safe side, we'll take all of these cigarette butts back and check them out. However, this should have little impact on the outcome of the case. ”

The three of them were chatting, and Gu Song suddenly walked over from the stairwell. Seeing that there was one more "uninvited guest" tonight, the marker wearing glasses couldn't help but muttered in his heart.

Gu Song greeted them with a smile, and before Xia Shi could speak, he said to himself: "The murderer came to the rooftop in advance, hid behind the stairwell, and patiently waited for the victim to appear. While the victim was smoking, the killer attacked the victim with a stone he picked up from the side of the stairwell, and after getting his mobile phone, he pushed him off the roof, killing him. After that, the murderer used the victim's mobile phone to send a text message to Mu Zi, leading Mu Zi to the rooftop, pretending that the two girls were about to meet. Combined with the anonymous letter he received earlier, Mu Zi will definitely come to the appointment. By the time Mu Zi came back to his senses, the murderer's framing had been completed. ”

Xia Shi nodded in agreement. In other words, the murderer knew that Ling Xiang had the habit of smoking on the rooftop at night. He first used the anonymous letter as a foreshadowing, and then used the content of the text message to strengthen the psychological impact of the anonymous letter on Mu Zi, calculated the right time, and skillfully lured Mu Zi to the bait and framed Mu Zi. The reason why he attacked the victim with stones, rather than directly subduing the other party, shows that the murderer may not be a physically strong person and is not sure about his own skills and physical strength. ”

"So the murderer of Ling Xiang should be a relatively thin person. I don't think the possibility that the murderer was a girl can be completely ruled out. As it stands......"

"Wait." Just when Gu Song and Xia Shi were very tacitly restoring the course of the case and speculating on the characteristics of the murderer, the marker wearing glasses suddenly interrupted them and asked, "Listen to what you mean, it seems that the murderer in this case is really someone else." ”

"Not likely." Gu Song immediately corrected. He turned around, looked at the other party seriously and seriously, and said, "I bet with you, the murderer in this case is not Mu Zi 100%. If you are willing to follow my advice, you should investigate the crime scene thoroughly and carefully now, and do not leave any clues behind. Otherwise, when you can't catch the real culprit later and need to revisit the scene, you will definitely regret it. ”

Gu Song's words made the man with glasses a little dissatisfied. If it weren't for Director Xia's face, he wouldn't have bothered to leak the investigation information of the case to unrelated people. He snorted, looked at Gu Song coldly and asked, "Who are you?" Came here to dictate our work. ”

"Oh, I forgot to introduce myself." Gu Song didn't have the same knowledge as the other party, and quickly returned to his usual smiling appearance, took out his ID and said, "My name is Gu Song, and I am from the Criminal Police Detachment of R City." ”

Hearing this name, the glasses man's face showed a slight expression of surprise, "You are Gu Song?" ”

"What, you know me?" Gu Song asked in surprise, but he didn't expect the other party to look at him as if he had changed a person, and looked at him with some admiration and asked, "You are the one who caught Tian Jiaxuan, right?" ”

Gu Song nodded inexplicably, and said in his heart that this was a fan or something. The other party continued: "Such a cunning murderer can be caught by you, it seems that what you said in today's case will not be wrong." ”

"Ah, no......" Gu Song scratched his hair embarrassedly, "We should still look at the problem rationally." For example, there are a lot of doubts in this case......"

Seeing Gu Song explain to the two trace examiners very seriously the reason why the murderer was someone else, Xia Shi's heart suddenly rose with warmth. Originally, tonight's case had nothing to do with Gu Song, he could completely ignore this matter and go home and sleep well. After all, in the period since the "4.7 Homicide", he has been the hardest working person in the entire criminal police team, and he still insists on working with a body of pain.

Thinking of this, Xia Shi felt that his opinion of Gu Song was indeed a bit extreme. In fact, deep down in his heart, he had already decided that Gu Song was a very good partner, and he was willing to believe that as long as the two of them were together, there was no problem that could not be solved. It's just that for the sake of face, Xia Shi has always refused to admit it.

Maybe it's time for those past grievances to be dissipated over time. There is still a long time to come, and as colleagues and partners, they can't always find fun in meaningless quarrels and mutual sarcasm, as they did in school. Even if you can't be friends, try not to think of each other as enemies.

The mobile phone in his pocket rang, and Xia Shi came back to his senses. He walked a little farther away, picked up the phone and asked eagerly, "Jin Yu, how is the situation over there?" ”

"I'm fine, the transcript is done. I'm just worried about Mu Zi......"

Xia Shi finally breathed a sigh of relief and comforted Xia Jinyu and said, "Don't worry, Muzi's affairs are up to us, and we will never let her be unjustly imprisoned." ”

"I believe in you, and I believe in Brother Gu Song. I just regret that at such a time, I can't be by Muzi's side and can't do anything for her. ”

"You have done a good job, I believe Muzi will be able to feel your heart. Let's talk about anything else, I've already said hello to the people from the criminal police team and asked them to take you home. ”

"Brother......" Xia Jinyu paused, as if he had made up his mind. Can you come and pick me up? I want to go to your apartment tonight and I don't want to go home......"

"What's wrong? Afraid that your parents will blame you for your early love? Or do you blame yourself for being nosy? ”

Xia Jinyu did not answer. After being silent for a long time, he said sadly: "Brother, I'm sorry, I always cause trouble for you." If it weren't for me, your family would ......."

"Jin Yu, don't say it!" Xia Shi stopped sharply, "So far, why are you still saying such things." ”

"But I've really caused you a lot of trouble since I was a child."

"Jin Yu, you were brought back by your father, and he treated you as his own son from the moment he decided to adopt you. My dad and I promised you that you would definitely catch that bastard and avenge your biological parents. No matter how long it has passed, we will never break our promise. I hope you can trust us, and I hope you can accept our care and care, because we have never treated you as a problem. ”
