The investigation of Liu Jun really surprised everyone.

Previously the so-called best suspect, now looks more like the best back pot man.

However, although Liu Jun has social media chat records as a tool to clear the charges, it does not mean that Liu Jun is not suspected.

Whether Liu Jun’s dictation lied or not is still uncertain, so Gu Chen can’t just believe his one-sided statement.

“Come with us to the technical section of the Municipal Bureau.” “We need your cooperation,” Gu suggested

“But You can. ” Although Liu Jun hesitated, he did not dare to contradict Gu Chen’s serious face and agreed directly.

After several people got on the bus, they went directly to the technical section of the Municipal Bureau.

At this moment, Gao Chuanfeng is testing the objects on the scene, and everyone is waiting patiently outside.

After a comparison, the time soon came to the end of the day.

Many police officers began to leave the office and head for the canteen.

But Gu Chen’s third criminal investigation team is still sitting in the waiting room.

Gao Chuanfeng, wearing a white coat, walked out of the detection room. Seeing that Gu Chen and others were still at the scene, he turned back to the waiting room and said, “haven’t you left yet?”

“Isn’t this waiting for your test report?” Gu Chen directly stood up and came to Gao Chuanfeng and asked him, “where are the things?”

“In such a hurry?” Gao Chuan Feng instinctively backward a contraction, a pair of embarrassed appearance.

“Don’t you tell us that this test is not finished yet?” Lu Weiwei is also closely followed by the killing, a look of questioning.

Gao Chuanfeng said with a smile, “I’ve been a forensic assistant for so long, and I think you’ve always been like a soul chaser every time. I feel like you’ve been treating our technical department as your home.”

“Why do you say so much? Is there anything? ” Officer Wang can’t sit still. The key is that he is hungry.

Get the test report as soon as possible, and kill it to the canteen as soon as possible.

“It’s hard to wait on you ancestors.” Takakawa shrugged his shoulders, put his hands into the pocket of his white coat, turned around and said, “stay here, I’ll get you.”

After a while, Gao Chuanfeng will be a test report form, personally sent to Gu Chen’s hand: “you want things I have been tested with you, the murder weapon, that is, the sting, there is no fingerprint on it.”

“I guess so.” Gu Chen looks at the data on the test form and shares it with Lu Weiwei, who stands on tiptoe.

“But there are fingerprints on the cup.” Gao Chuan Feng continued to add a sentence.

Gu Chen quickly turns to the next page and is surprised to find that there is only one fingerprint, which is completely matched with Liu Jun’s.

Gu Chen can’t help frowning. He looks back at Liu Jun, who is waiting at the corner of the waiting room. He turns to Gao Chuanfeng and asks, “you’re not doing this test.”

“What What? ” Also surprised by Gu Chen’s query, Gao Chuanfeng directly asked with a chuckle: “I said Gu Chen, do you doubt my detection level? Well, I’m a professional. ”

“I know you’re professional. I mean, in normal logic, this cup can’t have just one fingerprint.” Gu Chen also tells Gao Chuanfeng what he wants.

“I don’t understand.” Gao Chuanfeng directly shook his head in response.

At this time, police officer Wang and Yuan Shasha also came to Gu Chen’s side. They looked at Gu Chen in disbelief, as if Gu Chen had found something fishy in it.

“Elder martial brother Gu, do you mean there is something wrong with Liu Jun’s fingerprint left on the paper cup?” Yuan Shasha asked.

Gu Chen shook his head: “Liu Jun’s fingerprints remain on the paper cup. There is no problem in itself. The question is, why is there only his Liu Jun’s fingerprint on the paper cup? Have you ever thought about it? ”

“This one?” Yuan Shasha froze for a moment and asked Gu Chen weakly, “does elder martial brother Gu mean that sun Miao, who brews coffee, should also have fingerprints on it, but not now?”

That’s what it means Gu Chen held his chest in his hands and walked back and forth on the corridor for several times before he said again: “judging from our inspection of the scene, it seems that we experienced a fight in the office.”

“Yes.” Lu Weiwei nodded fiercely and said, “the office is in a mess. It seems that there is something big about the movement and stillness. The spilled coffee and the broken watch of the dead all indicate that the two sides did have a fight at that time.”

Gu Chen shook his head: “I don’t think so.”

“Not necessarily?” Officer Wang frowned and asked Gu Chen, “you mean There’s no fighting in the office? ”

“Senior brother Wang.” Gu Chen looked up at him and asked: “according to the normal situation, including the time point when the deceased and Liu Jun met, it seems that it can be concluded that the last one left the office, and the time when he was killed with the deceased was extremely short.”

“It seems that Liu Jun is most likely to complete the murder of the dead in such a short period of time.”

“But there is a problem, Liu Jun was also called to the scene, let alone the authenticity of this situation, even if it is, is he regarded as being used by others?””If this situation doesn’t exist, the chat records he shows us are just self directing and self acting, which is also a great risk. After all, we can find out the truth through our technical means.”

“If this is the case…” Lu Weiwei frowned and glanced at Gu Chen: “if this is the case, Liu Jun’s crime seems to be too obvious. I feel that if this is the case, the previous preparations are totally unnecessary.”

“Yes.” Yuan Shasha also agreed: “from the perspective of the whole case, it seems that the murderer’s goal is to throw the pot to Liu Jun, so it’s very coincident in time, and seems to know Liu Jun very well.”

“But if you think about it carefully, it is not difficult to see that the person who asked Liu Jun to meet must be the murderer, and he is the writer Liu Jun wants to see.”

“Xiao Yuan, that’s good.” Gu Chen is also admirable, thumbs up.

Yuan Shasha scratched the back of her head shyly and said in a low voice, “I just express my humble opinions on the basis of elder martial brother Gu’s conjecture. There is still a lot to learn from elder martial brother Gu.”

“Very good already.” Gu Chen also nodded slightly, looking at Liu Jun waiting in the room through the glass wall. He also said: “if Liu Jun is really a murderer, there is no need to make all the clues against him so obvious.”

“Besides, if he really wanted to kill the dead, he would never choose to be in such an obvious place as the office.”

“What do you say at that time?” Officer Wang suddenly interrupted and said, “I remember the watch on the dead man’s hand. When it was broken, it was fixed at 3:30.”

“As far as time is concerned, the time for meeting Liu Jun and him is also very short. Is it possible that as soon as Liu Jun leaves, the deceased is murdered?”

“There is only one possibility.” Gu Chen directly interrupted officer Wang’s speech, turned to look at him and said, “that is, the murderer is around.”

“You mean Acquaintances? ” Asked officer Wang.

Gu Chen nodded: “it is undeniable that those who can well coordinate the meeting time between Liu Jun and the dead, and who are very familiar with the deceased’s business negotiations, who will you think of first?”

“Sun Miao?” Police officer Wang was also conditioned to say the name of sun Miao, the assistant of the dead.

Gu Chen slapped a ring finger and said, “it’s sun Miao. It’s completely possible for her to finish the crime within a very short time after Liu Jun left.”

“But Lu Weiwei hesitated for a moment and looked up at Gu Chen: “but younger martial brother Gu, have you ever thought that the body of the dead is also big, and that sun Miao, we have all seen before, is a thin and weak woman.”

“With her bamboo figure, how could she kill the dead in a fight? It seems a little unrealistic, isn’t it? ”

“Yes.” Yuan Shasha, standing on one side, also agreed: “elder martial brother Gu, in terms of figure, sun Miao should not be the opponent of the dead at all. Moreover, it is too far fetched to make such a big noise in the office that after killing his own boss, he can still retreat all over the body.”

Gu Chen smiles, but also knows everyone’s concerns.

Therefore, Gu Chen was not in a hurry, but asked yuan Shasha, “Xiao Yuan, if I told you that the scene was in a mess, it was a false phenomenon deliberately created after the murderer succeeded, how would you judge?”

“A deliberate falsity?” Yuan Shasha was like a primary school monk who was suddenly named, and the whole person froze for a moment.

However, on the basis of the clues provided by Gu Chen, she quickly thought of the main points, and the whole person couldn’t help but wonder: “does elder martial brother Gu mean that sun Miao suddenly attacked the dead without knowing the death by taking advantage of his special relationship as the boss’s assistant?”

“Yes.” Gu Chen snapped his fingers and said, “that’s what I want to say, because from the scene, the dead man fell on his seat, and the sting hit his back and hit his heart.”

“From the point of view of the modus operandi of the crime, the victim was suddenly attacked in the back without the victim’s knowledge, thus leading to the death on the spot.”

There was a brief silence

All the people look at Gu Chen dully, with incredible in their eyes.

Just now, everyone’s ideas were still on the discussion of time, but Gu Chen changed his position and said that everyone’s thinking seemed to jump to another level.

Gao Chuanfeng, a forensic assistant who has been watching the three criminal investigation teams discuss with each other, also broke the scene calm after two seconds: “so the messy scene Gu Chen said was made by the murderer deliberately, in order to confuse you?”

“Yes.” Gu Chen is also a slap in Gaochuan Feng’s shoulder, let Gao Chuanfeng’s body suddenly sink.

“Previously I was not very sure, but now through Gao Chuanfeng’s detection, I found an important doubt, which can also be said to be sun Miao’s own loophole.”

“Leakage Loopholes? ” Yuan Shasha froze for a moment, but also quickly asked Gu Chen: “elder martial brother Gu, what is the loophole you found?”

“That’s it.” Gu Chen directly picked up the test report and said with a smile: “the test report of gaochuanfeng has made it very clear that there are only Gao Chuanfeng’s fingerprints on the paper cup.””So according to this understanding, this paper cup must have been used by Maple takagawa, and contains coffee residues, which have been mentioned in these test reports.”

“But have you ever thought that sun Miao said this when she was in Block B of Chenggong building. She said she was going to make tea for Liu Jun, but Liu Jun refused. He said he wanted coffee.”

“So sun Miao made a cup of coffee for him. After that, Liu Jun left the office and put the cup of coffee on Sun Miao’s desk at will.”

“I remember.” Seeing Gu Chen mention it, Lu Weiwei suddenly realized: “and this sun Miao also said that she threw the paper cup into the garbage can, that is, the paper cup you found.”

“So why didn’t sun Miao’s fingerprints appear?” Gu Chen asked everyone again.

All of a sudden, there was a brief silence at the scene, and everyone seemed to understand it.

Lu Weiwei still clearly remembers that the reporter is sun Miao, the assistant of the deceased.

In the short time from Liu Jun’s departure to the death of the dead, only sun Miao could easily attack from behind.

And from the working habits of the deceased, business negotiations with people must be made in advance, even their own lovers.

According to this understanding, after the meeting of the last Liu Jun, no one else appeared.

The only person who can get in and out of the dead’s office is sun Miao.

“So the watch of the dead can’t be broken in the fight. The time on the watch is just an illusion?” Lu Weiwei thinks carefully and looks at Gu Chen with horror.

Gu Chen nodded slightly and said: “at present, the time on the watch is just an illusion. The chaos and coffee on the scene are also illusory, because there is no fight in fact.”

“In the end, there was only Liu Jun’s fingerprint on the paper cup, but Sun Miao clearly told us that she threw the paper cup into the garbage can by herself, and there should be her fingerprints on the paper cup.”

“So, sun Miao is lying. In fact, she is the murderer.” Officer Wang frowned, and there was no good airway.

Also listen to Gu Chenyi finishing, it seems that the situation on the scene is not without loopholes.

Sun Miao put on his gloves and stabbed the boss to death with poison. Then he forged the scene and tried to frame Liu Jun, but he showed his horse’s foot.

While everyone is still happy to find the loopholes on the scene, Gu Chen directly takes the rolled up test report, knocks his palm, and turns around and walks away.

Lu Weiwei raised her head and asked, “brother Gu, where are you going?”

“Look for sun Miao.” Gu Chen continues to walk forward and raises the test report on his right hand.

……

……

It’s 7:30 p.m.

Gu Chen, Lu Weiwei and police officer Wang, who have just finished dinner, have been waiting for a long time in the second interrogation room of Furong Branch.

Before long, Yuan Shasha took sun Miao to the scene, arranged her to sit on the opposite interrogation chair, and then directly came back to turn on the camera.

After that, he moved a stool and sat quietly beside Gu Chen.

“Sun Miao.” Gu Chen opened the transcript and asked her.

Sun Miao was trembling, but he did not know why: “yes, it was me.”

“Do you know why you were asked to come here?” Gu Chen asked again.

“You You want to know about the boss? ” Sun Miao said weakly.

Gu Chen shakes his head.

“Well Do you want to know who the boss has met with recently

Gu Chen still shakes his head.

Looking at Gu Chen’s sharp eyes, sun Miao suddenly had an ominous premonition, and once again he said in a low tone: “that What do you want me to do

“We want to know, why did you kill your boss?” Gu Chen said.

“Why What? ” On hearing this, sun Miao looked at Gu Chen in a daze and said with a sneer: “police comrade, you Can you make a mistake? I called the police

“I know you called the police and I answered the phone.” Lu Weiwei also has a saying.

“Well What do you mean Sun Miao seems to be greatly aggrieved, the whole person suddenly tears.

Gu Chen opened the drawer directly, took out the paper cup in the transparent forensics bag, and said, “do you remember this paper cup?”

“Remember, isn’t this the paper cup you found in the trash this afternoon?” Sun Miao said.

But when he looked back, he asked, “but what do you want me to do with this?”

“You said that Liu Jun wanted to drink coffee, so you made coffee for him, and then when Liu Jun left, you threw the paper cup into the garbage can, right?” Gu Chen said.

Sun Miao was stunned and his heart was pounding.

She looked at the paper cup in Gu Chen’s hand and sipped the water channel: “I Did I say that? I I don’t remember. ”

“Hehe, don’t you remember?” Officer Wang also shook his head and put the law enforcement recorder in the drawer directly on the table: “we have records of police handling cases, you don’t remember, but the law enforcement recorder does.””Ah? Did I say that? ” Sun Miao is not nervous at the moment, although she still looks calm.

However, for a few experienced interrogators, sun Miao’s various small movements seem to have betrayed her.

Gu Chen turned her right hand and reminded her: “you said Liu Jun was the last one to leave the office. After that, you didn’t know the situation. You also went downstairs to get the express.”

“But the surveillance video sent to us by our colleagues shows that you did go downstairs to pick up the express, but it didn’t take much time. During this time, you can finish the crime.”

“Wait Wait a minute. ” Sun Miao suddenly interrupted Gu Chen and retorted, “what are you talking about? I? How can a weak woman assassinate the boss? He is a big man. ”

“That’s not the point.” Gu Chen directly retorted and went back, saying: “you can take advantage of people’s unprepared and start from behind your boss. Moreover, if you stab your heart, your boss must be killed on the spot.”

“But But even if you’re right, is there still time? Although I returned to the company at that time, it was already over 3:30, but the boss was obviously killed before 3:30, because his watch was fixed at 3:30, and I was not at the scene at that time. ”

Gu Chen waved his left index finger and said, “you just used a cover up, just like you create a messy fighting scene in the office.”

“Just move your hands and feet on the victim’s watch, smash the quartz screen, and adjust the time back to the time when you are not at the scene. This can be done completely. I can hide it for you.”

Speaking of this, Gu Chen took out the broken watch from the drawer again.

Then, using a thin wire, Gu Chen through the broken quartz gap, the watch time will be adjusted at will.

After finishing this series of demonstrations, Gu Chen looked up at Sun Miao and asked her, “what else do you want to say?”
