"I'm going to the scene of the crime to find the evidence I saw at the time, and I'm going to ask you police to tell me all the details about the murder. ”

"But we have already identified the murderer, and the evidence is also sufficient, so there is no need to find any more evidence, since you are an eyewitness, then you can make a corroboration, you say, is the murderer her?" Yu Zheng pointed to Professor Lin standing in the corner.

Looking at Professor Lin's graceful figure, Qin Mu shook his head and said, "It's not her, the murderer is someone else." ”

When Yu Zheng heard this, he immediately frowned. "It's not her? Who's that? You're not giving false testimony, are you?"

Qin Mu hurriedly denied it: "No, absolutely not, Professor Lin is really not the murderer, I can find evidence to prove that the murderer is someone else, you let me go into the scene of the crime to find out!"

He needs to explore the scene, only by finding out the real murderer, can he get rid of Professor Lin's suspicion, as soon as he thinks of this, Qin Mu feels a little uncomfortable, generally his tasks are to kill people, fight terrorism, and obtain intelligence, this time is good, not only to be a bodyguard, but also to act as a detective......

Yu Zheng has the dignity of being a policeman, he feels that collecting evidence should be his job, how can he let a witness do it, so he frowned and said: "You directly tell me what the crime is and what the evidence is, our police will find it ourselves, and we don't need you to interfere." ”

"I'm not really sure that the evidence is still at the scene, and if you can't find it, I can't afford to say that I'm talking nonsense and disrupting official business, so I'd better go find it myself. Qin Mu hurriedly thought of a reason, refused to prevaricate, just kidding, I don't know anything now, how can I tell you evidence......

Gu Gongming didn't believe that Professor Lin would be a murderer, but when he heard Qin Mu say that there was a new murderer, he suddenly came to his senses, and hurriedly echoed: "Yes, Captain Yu, you just let Teacher Qin go and find it yourself, he is also in order to prevent the good people from being wronged and the evil criminals from going unpunished! Anyway, the evidence collection work at the crime scene has been completed, and there is no need to worry about causing damage to the scene." ”

Qin Mu said that there was another murderer, and Gu Gongming also tried his best to echo beside him, Yu Zheng had no reason to refuse, so he had to nod and said: "Okay, I'll go in with you, if you have any questions, you can ask me directly." ”

As soon as Yu Zheng's voice fell, a woman behind him said in a strange manner: "I said that you police also have no brains, and if someone comes and says that he is an eyewitness, you will believe it, and the evidence is conclusive that the murderer has been found, and you have to re-investigate, hey." ”

Listening to the voice, Qin Mu saw a middle-aged woman with a wide body and a fat body, and a "hateful" face, she stopped herself from finding the truth, Qin Mu felt that she was just an abomination!

"Although it can be said that the evidence is conclusive, there are still some doubts, and our police have their own code of conduct, so we don't need you to point fingers!"

It seems that he is not alone, he still has allies, at least this Captain Yu is the same as me, and he hates her very much, listening to Yu Zheng's words, Qin Mu is a little relieved.

"Humph!" the woman snorted coldly and stopped talking.

"Come with me. After Yu Zheng finished speaking, he walked into the women's bathroom in the corner, and looking at the direction he left, Qin Mu understood. "The murder took place in the women's bathroom......"

Just as Qin Mu was about to move, Bai Ye suddenly walked over, covered his mouth with his right hand, and whispered to Qin Mu: "Hey, I said, the fiancé who suddenly appeared, didn't you just arrive in Xijing? Why did you lie to the police and say that you were a witness?"

Although the fiancé who suddenly appeared was right, Qin Mu always felt strange when he heard it, and after thinking about it, he didn't seem to refute it, so he had to answer: "If I don't lie to him, how can I have the opportunity to enter the scene?"

"What are you doing in the field?"

"If I don't go to the scene and investigate in person, how can I find out the real murderer, and how can I wash away Professor Lin's suspicion?" Qin Mu held back the last thing he wanted to say in his heart, are you stupid?

"Oh......" As if suddenly remembering something, Bai Ye hurriedly said in surprise: "Hey, aren't you already my sister's fiancé? Why do you still call her Professor Lin? instead of my sister's real name, Lin Yaoyao?"

"This ......" Qin Mu was stunned, and was about to think of something to say, when Yu Zheng's urging voice suddenly came from the bathroom. "Teacher Qin?"

"It's coming, it's coming!" Turning his head to look at Bai Ye, Qin Mu smiled and said, "I'll tell you when this case is over, I'll go first." ”

"Okay, I'll leave my sister's suspicion to you. Getting back to business, Bai Ye looked at Qin Mu with a worried face and said.

"Rest assured. With that, Qin Mu walked away.

Opening the door of the women's bathroom, there were four toilet cubicles directly in front of Qin Mu, and this row of toilet cubicles was parallel to the wall where Qin Mu opened the door.

Qin Mu found that except for the toilet cubicle opposite him when he opened the door, there was no window in the other three toilet cubicles.

Yu Zheng looked at Qin Mu who came in and handed over the photo in his hand. "Yes, this is a photo of the scene, the female corpse has been transported, you can just look at the photo. ”

"Is this toilet cubicle with windows where the deceased was killed?" Qin Mu asked, pointing to the toilet cubicle with blood stains in front of him.

"Yes, the female corpse fell face up in this toilet cubicle, because the doors of these cubicles were pushed inward, so the female corpse that fell to the ground just blocked the wooden door pushed inward, in order not to destroy the scene, we took these photos lying on top of the cubicle. ”

As soon as he finished speaking, Yu Zheng said suspiciously: "There is no other place except for the tree-lined path outside this window where you can see the murder scene, since you are a witness, then you should have seen the murder process from here, why do you ask me? I said that you kid will not be intentional to make trouble, right?"

Qin Mu panicked in his heart, and quickly explained: "Of course I know the location of her death, just to confirm, because I didn't see it very clearly at the time, for the sake of rigor, I still asked clearly." ”

"I hope so......"

Ignoring Yu Zheng no more, Qin Mu looked at the photo in his hand.

In the photo, the female corpse's mouth was wide open, her eyes were bulging, and she was still horrified when she died because of the fright.

On the neck of the corpse, there was a deep purple-red strangulation mark, and in addition, there were eight or nine vertical downward bloody paw prints and strangulation marks on the neck.

It is clear that these paw prints were caused by the deceased's desperate struggle with both hands holding on to the rope when the killer strangled the deceased in the rear.

His gaze continued to move downward, and Qin Mu saw that there was a large amount of blood flowing on the left chest of the corpse, and the white short sleeves of the corpse had been completely dyed red.

Yu Zheng saw Qin Mu seeing this location and explained to him: "After forensic identification, the cause of death of the deceased was a penetrating wound to the left chest, the sharp blade was pierced into the heart, killing with one blow, and the strangulation marks on the neck only suffocated him and fainted, not directly strangulation. ”

"Where's the murder weapon?"

"The short knife that pierced the heart was only found next to the corpse, and the rope that strangled the deceased was not found, you see, this is a picture of the short knife. ”

After taking the photo, Qin Mu wondered in his heart: "Only there is blood on the blade, but there is no blood on the handle, shouldn't it...... There was so much blood from the deceased, and it stands to reason that there would be blood stains on the hilt of the knife, why not?"

Puzzled, Qin Muchao Yu Zheng continued to ask: "Then what is your reasoning now? Why is Professor Lin the most suspicious? Also, Captain Yu, can you tell me who found the body, and what is the whole story of this matter?"

"Good. ”

After Yu Zheng finished speaking, he shouted out of the door: "Xiao Wang, you come in." ”

In a moment, a policeman in a police uniform with a wooden face walked in. "Team Yu, what's the matter?"

"You tell him the whole story of the case. ”

Looking at Qin Mu, the police officer said slowly: "The deceased's name is Zhao Jing, age 31, is a teacher at Xijing Medical University, found that the deceased was a student, after receiving the report, we inspected the scene, and also adjusted the surveillance, we found that the deceased entered the toilet at two o'clock this afternoon, and after her, two more people entered the toilet one after another, these two people have been interrogated, the first person to come in said that she did not find anything abnormal, and did not see the body." ”

The second person who came in also said that she didn't see the body, but one thing she found strange was that she felt that the door was a little difficult to open when she entered, and when she opened the door, she heard a clanging sound from the toilet cubicle where the deceased was! It wasn't until the third person entered the toilet, that is, when the female college student entered the toilet, that she found a lot of blood flowing from the toilet cubicle, and she hurriedly came out of the toilet to call the police, and the time when the student came out of the toilet was 2:20 p.m., which means that the deceased was killed within these 20 minutes. ”

Qin Mu nodded slightly, motioning for him to continue.

"After investigating the scene, we found that the toilet cubicle where the deceased was located had almost become a secret room, because her body blocked the wooden door of the toilet, so unless her killer could move her body through the air and block the wooden door from the inside, the people in the toilet were not suspected of murder. ”

"Well, what does that mean it's almost a secret room?" Qin Mu asked, looking at the toilet cubicle.

"One is because when the body is found, the window of this toilet cubicle can be opened, and the second is because there are openings above and below the toilet, you know, public toilets are generally not sealed, but this opening is useless, because the three people who entered after the deceased could not climb through!"

"Therefore, apart from the possibility that someone from the outside will come in through the window and kill someone, this toilet cubicle is a secret room for those three people!"

"Well, go on. ”

"All the money and belongings of the deceased were taken from her, the windows were wide open, and it was impossible for the people inside the toilet to kill her, so we concluded that this was a case of robbery and murder, and the murderer must have been the one who came in through the window to kill the deceased, and then escaped through the window. ”

Qin Mu disagreed, pointed to the photo and asked: "But the compartment where the deceased is located is not locked from the inside, but her body blocks the wooden door, don't you think it's strange? Why didn't she lock it from the inside when she went to the toilet? Also, since it was a robbery case, what does it have to do with Professor Lin? Professor Lin is worth a lot of money, can he go up and rob him?!"

"There are more people who go to the toilet and don't lock the door, what's so strange about this, as for why Professor Lin is the murderer, it is because we have conclusive evidence, we have seen the monitoring of the tree-lined path behind the window, in the twenty minutes of the crime, only Professor Lin passed by, and no one else appeared, and this is not the most important thing, the most important thing is that we tested the blood of the deceased on Professor Lin, so may I ask, if she is not the murderer, why is there a blood stain of the deceased on her body?"

Qin Mu raised his eyebrows, and suddenly felt that things were tricky......

"I've seen the scene and understood the situation, what about the evidence?" Yu Zheng asked as he looked at Qin Mu.

"I'm almost there, but I still have a question, so I need to meet the three people who have appeared in the past twenty minutes. "After listening to the whole situation of the case, Qin Mu still didn't understand the murderer's murder methods, anyway, seeing the real murderer first, maybe it would help me?

Because the murderer is not Professor Lin, the real murderer must be among those three people, Qin Mu is very sure of this, then the matter is much easier.

“……”

"Trust me Captain Yu, I'll be able to identify the real murderer. ”

"Okay, you and I come out, they're all out there. ”

As soon as Qin Mu took a step, he felt as if he had stepped on something foreign on his right foot, and when he raised his foot, he saw a palm-sized leather ring standing on the ground, picking it up and pulling it, it was quite elastic.

Seeing Qin Mu's move, Yu Zheng said with a little dazed: "It's strange to say, when we arrived here, there were a lot of these holsters on the ground, even the compartment where the deceased was, I don't know where it came from, it's this suspicion, I haven't been able to figure it out, but it's been cleaned up a lot just now, I didn't expect there to be left, I ......"

Yu Zheng didn't listen to a word of Qin Mu's words, because he had already fallen into thought......

"Holster, do you mean ......" Qin Mu raised his eyebrows, then turned around and leaned up towards the top of the compartment.

"Hey, what are you doing Teacher Qin?"

Ignoring Yu Zheng, Qin Mu lay on the top of the wooden door and searched carefully!

"There it is!"

Qin Mu looked at a vertical mark on the wooden door and smiled, along the direction directly opposite the vertical mark, Qin Mu saw the doorknob of the bathroom, it was an "L" shaped handle, the long end was vertically underground, and the short end was fixed on the door......

The more Qin Mu thought about it, the more he understood, and he couldn't help but show a smile on his face. "That's right..."

"Teacher Qin, come down quickly. ”

"Okay, I'll come down now. ”
