The investigation into Liu Jun really surprised everyone.
The so-called best suspect before now seems more like the best scapegoat.
However, although Liu Jun has social media chat records as a tool to clear his name, it does not mean that Liu Jun is not suspected.
It is not yet certain whether Liu Jun's oral statement was a lie, so Gu Chen could not just believe his words.
"Come with us to the Technical Section of the Municipal Bureau." Gu Chen suggested: "We need your cooperation."
"But...it's okay." Although Liu Jun hesitated, seeing Gu Chen's serious look on his face, he didn't dare to refute and agreed directly.
After a few people got on the bus, they went directly to the Technical Section of the Municipal Bureau.
At this moment, Gao Chuanfeng was inspecting the objects on site, and everyone was waiting patiently outside.
After some comparisons, it was time to get off work quickly.
Many police officers began to leave the office and headed towards the canteen.
However, Gu Chen's Criminal Investigation Team Three was still sitting in a row in the waiting room.
Gao Chuanfeng, wearing a white coat, walked out of the testing room and saw that Gu Chen and others were still there, so he returned to the waiting room and greeted everyone: "You haven't left yet?"
"Isn't this the test report waiting for you?" Gu Chen stood up directly, came to Gao Chuanfeng, stretched out his hand and asked him: "Where are the things?"
"You shouldn't tell us that this test hasn't been completed yet, right?" Lu Weiwei also followed closely, looking like she was launching an attack to accuse her.
Gao Chuanfeng chuckled and said: "I have been a forensic assistant for so long, and you, Gu Chen, are the only ones who act like a ghost every time. I feel like you almost treat our technical department as your home."
"Why are you talking so much? Do you have anything?" Officer Wang also couldn't sit still. The key is that he was hungry.
If you get the test report early, you can go to the canteen as soon as possible.
"It's really hard to take care of our ancestors when we meet you." Gao Chuanfeng shrugged, put his hands into the pockets of his white coat, turned around coquettishly and said, "Stay here, I'll get it for you."
Not long after, Gao Chuanfeng personally delivered a test report form to Gu Chen: "I have tested everything you want. The murder weapon, the stinger, does not have any fingerprints on it.
."
"I guessed it." Gu Chen looked at the data on the test form and shared it with Lu Weiwei who was standing on tiptoe.
"But there are fingerprints on the paper cup." Gao Chuanfeng continued to add.
Gu Chen quickly turned to the next page and was surprised to find that the test result showed that there was only one fingerprint, which completely matched Liu Jun's fingerprint.
Gu Chen couldn't help but frown, and looked back at Liu Jun, who was waiting in a corner of the waiting room, and then asked Gao Chuanfeng: "Your test is wrong."
"What... what?" Gao Chuanfeng was also shocked by Gu Chen's question. He laughed directly and asked: "Gu Chen, are you doubting my testing level? I'm a professional."
"I know you are a professional. I mean, according to normal logic, there is no way this paper cup has only one fingerprint." Gu Chen also told Gao Chuanfeng what he was thinking.
"I don't understand." Gao Chuanfeng shook his head directly in response.
At this time, Officer Wang and Yuan Shasha also came to Gu Chen's side. They looked at Gu Chen in disbelief, as if Gu Chen had discovered something fishy.
"Senior Brother Gu, do you mean that there is something wrong with Liu Jun's fingerprints remaining 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 Liu Jun's fingerprint on the paper cup? Have you ever thought about this problem?"
"This?" Yuan Shasha was stunned for a moment and asked Gu Chen weakly: "Does Senior Brother Gu mean that Sun Miao, who made the coffee, should also have fingerprints on it, but now there is no fingerprint?"
"Yes, that's what I mean." Gu Chen crossed his arms and walked up and down the aisle a few times before adding: "From what we inspected the scene, it seems that there was a fight in the office."
"Yes." Lu Weiwei nodded fiercely and said: "The office was in a mess, and there seemed to be a lot of movement. The spilled coffee and the deceased's broken watch all showed that the two parties had indeed experienced 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 was no fighting in the office?"
"Senior Brother Wang." Gu Chen looked up at him and asked: "If we follow normal circumstances, including the time when the deceased met Liu Jun, it seems that we can conclude that the time between the last one leaving the office and the death of the deceased was extremely short.
"
"To complete the murder of the deceased in such a short period of time, Liu Jun seems to be the most likely."
"But there is a question. Liu Jun was also called to the scene. Not to mention the authenticity of this situation, even if it is, is he being used by others?"
"If this situation does not exist, and the chat records he showed us were just self-directed and self-acted, the risk would be extremely high. After all, with our technical means, we can also find out the truth."
"If this is the case..." Lu Weiwei frowned slightly and glanced at Gu Chen: "If this is the case, it seems too obvious that Liu Jun committed the crime. I feel that if this is the case, all the previous foreshadowing is completely unnecessary.
."
"Yes." Yuan Shasha also agreed very much: "Judging from the entire case, it seems that the murderer's goal was to pass the blame to Liu Jun. Therefore, the timing was very coincidental and he seemed 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 wanted to meet."
"Xiao Yuan, that's well said." Gu Chen also gave a thumbs up in admiration.
Yuan Shasha scratched the back of her head shyly and said softly: "I am just expressing my own superficial opinions based on Senior Brother Gu's speculation. There are still many things to learn from Senior Brother Gu."

If he 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 deceased, he would never choose to do it in an obvious place like the office."
"What about the time?" Officer Wang suddenly interrupted and said, "I remember that the watch on the deceased's hand was fixed at 3:30 when it broke."
"In terms of time, the time spent meeting Liu Jun and him was also very short. Could it be that the deceased was murdered as soon as Liu Jun left?"
"There is only one possibility." Gu Chen directly interrupted Officer Wang, turned to look at him and said, "That is, the murderer is right next to him."
"You mean...an acquaintance?" Officer Wang asked.
Gu Chen nodded: "It is undeniable that someone who can coordinate the meeting time between Liu Jun and the deceased very well, and is very familiar with the deceased's business negotiations, who will you think of first?"
"Sun Miao?" Officer Wang also reflexively said the name of the deceased's assistant, Sun Miao.
Gu Chen snapped his fingers and said, "It's Sun Miao. It's entirely possible for her to complete the crime in a very short time after Liu Jun left."
"But... Lu Weiwei on the side hesitated for a moment and looked up at Gu Chen: "But Junior Brother Gu, have you ever thought that the deceased was also quite tall, and that Sun Miao, we have all seen him before, that is a
A thin woman."
"With her bamboo body, how could she kill the deceased during a fight? It seems a bit unrealistic, right?"
"Yes." Yuan Shasha, who was standing aside, also agreed: "Brother Gu, in terms of figure, Sun Miao should not be a match for the deceased at all, and after making such a big noise in the office and killing his boss,
It would be too far-fetched to be able to escape unscathed."
Gu Chen smiled, knowing everyone's concerns.
Therefore, Gu Chen was not in a hurry and just asked Yuan Shasha: "Xiao Yuan, if I told you that the mess at the scene was a false phenomenon deliberately created after the murderer succeeded, how would you judge it?"
"Deliberately created false phenomenon?" Yuan Shasha was like a primary school monk who was suddenly called out, and her whole body was stunned for a moment.
However, based on the clues provided by Gu Chen, she quickly thought of the key points, and she couldn't help but be shocked: "Does Senior Brother Gu mean that Sun Miao used his special relationship as the boss's assistant to kill the deceased without his knowledge?
, suddenly launched a surprise attack on him, and killed him with one blow?"
"Yes." Gu Chen snapped his fingers and said, "That's what I want to say, because judging from the scene, the deceased fell on his seat, and the stinger struck from the back, hitting him directly.
heart."
"Judging from the modus operandi of the crime, the victim was suddenly attacked in the back without the deceased's knowledge, which resulted in fatal injuries on the spot."
The scene suddenly fell silent for a short period of time...
Everyone looked at Gu Chen blankly, with disbelief in their eyes.
Just now, everyone's thoughts were still on the discussion of time, but when Gu Chen changed his position, everyone's thoughts seemed to jump to another level.
Forensic assistant Gao Chuanfeng, who had been watching the three criminal investigation teams discussing each other, suddenly broke the calm of the scene after being stunned for two seconds: "So the messy scene Gu Chen mentioned was completely created deliberately by the murderer.
Just to confuse you?"
"Yes." Gu Chen also slapped Gao Chuanfeng on the shoulder, causing Gao Chuanfeng's body to suddenly sink.
"I wasn't very sure before, but now through Gao Chuanfeng's testing, I have discovered an important doubt, which can also be said to be Sun Miao's own loophole."
"Leak... loophole?" Yuan Shasha was stunned for a moment, and then quickly asked Gu Chen: "Senior Brother Gu, what is the loophole you found?"
"That's it." Gu Chen directly picked up the test report and said with a smile: "Gao Chuanfeng's test report has made it very clear that there are only Liu Jun's fingerprints on the paper cup."
"Then according to this understanding, this paper cup must have been used by Liu Jun, and it contains coffee residue, which is mentioned in these test reports."
"But have you ever thought about it. When we were in Building B of Chenggong Building, Sun Miao said this. She said she was going to make tea for Liu Jun, but Liu Jun refused. He said he wanted coffee."
"So Sun Miao personally made him a cup of coffee. Later, when Liu Jun left the office, he randomly placed the paper cup of coffee on Sun Miao's desk."
"I remember." Seeing Gu Chen mention it, Lu Weiwei suddenly realized: "And this Sun Miao also said that she was the one who threw the paper cup into the trash can in the end, which is the paper cup you found."
Suddenly there was another brief moment of silence, and everyone seemed to have understood.
Lu Weiwei still clearly remembers that the person who reported the crime was the deceased's assistant Sun Miao.
Moreover, in the short period of time between Liu Jun's departure and the death of the deceased, only Sun Miao could easily attack from behind quietly.
And judging from the work habits of the deceased, business negotiations with others must be made in advance, even for his lover.
According to this understanding, after the last meeting with Liu Jun, no one else showed up.
The only person who could enter and leave the deceased's office was Sun Miao.
"So the watch of the deceased could not have been broken during the fight. The time on the watch is just an illusion?" Lu Weiwei looked at Gu Chen with great fear.
Gu Chen nodded slightly and said: "That's it for now. The time on the watch is just an illusion. The chaos and coffee at the scene are also an illusion, because there is actually no fighting."
"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 trash can herself, so her fingerprints should be on the paper cup."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "So, Sun Miao is lying. In fact, she is the murderer." Officer Wang frowned, and he felt bad.
After listening to Gu Chen's review, it seemed that the situation at the scene was not without loopholes.
Sun Miao put on gloves and stabbed her boss to death with a poisonous thorn. Then she faked the scene and wanted to frame Liu Jun as the blame, but accidentally exposed the truth.
While everyone was still rejoicing at the discovery of the on-site vulnerability, Gu Chen directly took the rolled-up inspection report, tapped his palm, turned around and left.
Lu Weiwei raised her head and asked, "Junior Brother Gu, where are you going?"
"Look for Sun Miao." Gu Chen continued to walk forward and raised the test report on his right hand.
…
…
7:30pm.
Gu Chen, Lu Weiwei and Officer Wang, who had just finished dinner, had been waiting in the interrogation room No. 2 of Furong Branch for a long time.
Not long after, Yuan Shasha brought Sun Miao to the scene, arranged her to sit on the interrogation chair opposite, and then came back directly to turn on the camera.
Then he obediently moved a stool and quietly sat next to Gu Chen.
"Sun Miao." Gu Chen opened the notebook, raised his head and asked her.
Sun Miao was trembling with fear and didn't know why, "Yes, it's me."
"Do you know why I called you here?" Gu Chen asked again.
"You...you want to know about the boss's situation?" Sun Miao said weakly.
Gu Chen shook his head.
"Then... you want to know who the boss has interacted with recently?"
Gu Chen still shook his head.
Sun Miao looked at Gu Chen's sharp eyes, and suddenly felt an ominous premonition, and said in a low tone again: "Then...then why are you looking for me?"
"We want to know, why did you kill your boss?" Gu Chen said.
"What... what?" When Sun Miao heard this, she looked at Gu Chen dumbfounded and sneered: "Comrade police, are you... are you mistaken? I was the one who called the police!"
"I know it was you who called the police, and it was me who answered the call." Lu Weiwei also had something to say.
"Then... what do you mean?" Sun Miao seemed to have been greatly wronged, and her whole body suddenly burst into tears.
Gu Chen directly opened the drawer, took out the paper cup from the transparent evidence collection bag, and said, "Do you remember this paper cup?"
"Remember, isn't this the paper cup you found in the trash can this afternoon?" Sun Miao said.
But after thinking about it, he asked again: "But why are you asking me this?"
"You said Liu Jun wanted to drink coffee, so you made him coffee, and then when Liu Jun left, you threw the paper cup into the trash can, right?" Gu Chen said.
Sun Miao was stunned, and her heart was pounding.
She looked at the paper cup in Gu Chen's hand, took a sip and said, "I...did I say that? I...I don't remember."
"Haha, don't remember?" Officer Wang also shook his head and put the law enforcement recorder in the drawer directly on the table: "Our police have records when handling cases. You don't remember, but the law enforcement recorder does."
"Ah? Did I say that?" Sun Miao was extremely nervous at the moment, although she still seemed to be pretending to be calm.
But to several people with rich interrogation experience, Sun Miao's various little moves seemed to have betrayed her.
Gu Chen turned the pen with his 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 delivery."
"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. You could have completed the crime during this time."
"Wait...wait a minute." Sun Miao suddenly interrupted Gu Chen's words and retorted: "What on earth are you talking about? Me? How can a weak woman assassinate the boss? He is a big man."
"That's not the point." Gu Chen retorted directly and said, "You can definitely take advantage of someone's unpreparedness and attack your boss from behind. And if you stab him in the heart, your boss will definitely be killed on the spot."
"But...even if you are right, is there still time? Although I returned to the company at that time, it was already past 3:30, but the boss was obviously killed before 3:30, because he
My watch was fixed at 3:30, but I was not there at that time."
Gu Chen waved his left index finger and said: "You just used a blind trick, just like you created a fight scene in the office that was a mess."
"You only need to tamper with the deceased's watch, smash the quartz screen, and set the time back to a time when you were not present. This is completely possible, and I can demonstrate it to you."
Having said this, Gu Chen took out the broken watch from the drawer again.
Then, using a thin wire, Gu Chen adjusted the watch time at will through the cracks in the broken quartz.
After completing this series of demonstration operations, Gu Chen looked up at Sun Miao and asked her: "Is there anything else you want to say?"
