Card Room - 391. Mime private 545

[Chapter 545, the truth]

When Xiao Lou and Tang Ci went out together, Yu Hanjiang was waiting for them in the corridor. The man in the police uniform was leaning against the window with his hands wrapped around his chest, his brows frowned tightly, as if thinking about something.

Looking at Xiaolou’s gaze, Yu Hanjiang immediately took a step forward and said in a low voice: “Let your friend find a good lawyer so soon, are you planning to let this lawyer defend you?”

Xiao Lou’s expression was calm: “After all, I don’t understand the law, and I don’t know what to say and what not to say.”

Tang Ci glanced at the two and said to Xiao Lou: “Professor Xiao, please rest assured, I will definitely pay you back.”

Yu Hanjiang raised his eyebrows and looked at Tang Ci with calm and sharp eyes, obviously not believing what he said.

Tang Ci nodded towards Yu Hanjiang, turned and walked away calmly. Xiao Lou was taken back to cell 1. Yu Hanjiang stood at the door of the cell, looked at him through the bars, and asked, “Did you think of new clues?”

Sitting on the wooden bed, Xiao Lou looked serious: “Team Yu doesn’t think there are many strange things in this case?”

Yu Hanjiang motioned for him to continue.

Xiao Loudao: “The evidence you have, first, is the call record between me and Ning Xue; second, the hairs of Liu Qiao and I were found at the autopsy site, combined with the photo of me in Ning Xue’s mobile phone, and guessed me. The relationship with her…” Xiao Lou paused, and said with a certain tone: “However, these two evidences are not the so-called’iron proof’.”

“Oh? This is all evidence that is very unfavorable to you. Is your explanation still that the phone number and hair were stolen?” Yu Hanjiang said coldly, “But this explanation is not very convincing, neither do you Maybe use this explanation to persuade the judge.”

“Team Yu, where did you find the phone of the deceased Ning Xue?”

“She accidentally left her backpack in the square where the fireworks were set off on New Year’s Eve…” At this point, Yu Hanjiang frowned suddenly and raised his head to meet Shang Xiao Lou’s calm gaze. He suddenly reacted: ” At 9pm on the 31st, Ning Xue answered the phone, then came to the lake and was pushed down the lake. The time we received the alarm was around 9:15pm. Her mobile phone was lost in the square. If, she was then I answered the phone in the square, then she…”

“Then she didn’t have time to rush back to the scene of the crime.” Xiao Lou said calmly, “If it is usual, to come to the Conservatory from the central square, a taxi would be enough for 10 minutes. However, on the evening of December 31st, due to the opening of the square. Fireworks to celebrate the New Year. According to the usual practice in previous years, there will be traffic control around the square, taxis need to detour, and she can’t get a taxi at all.”

“…” Yu Hanjiang’s mind gradually became clearer.

The location of the deceased’s mobile phone did not match the time and place of the crime. This is the first loophole.

The previous reasoning was that Ning Xue picked up Xiaolou’s phone and was killed by Xiaolou at the lake. But on the evening of December 31st, if she really answered the phone, she would pick up the phone at the Fireworks Plaza at 9 o’clock and show up at 9:15. In the Conservatory, it is impossible.

That proved that the 9 o’clock call was definitely not answered by Ning Xue herself, and her mobile phone should have been in another person’s hand at that time.

Since Ning Xue didn’t pick it up, it wouldn’t be Xiao Lou.

The mobile phone is only used as a tool to forge a false certificate of “Xiaolou and Ning Xue talking”.

Seeing Yu Hanjiang’s brows frown, he obviously understood what he meant, Xiao Lou went on to say: “I’ll analyze it for Team Yu. At 9 o’clock, the murderer must have seen me and Liu Qiao at the Conservatory of Music, so he used The 136 mobile phone number prepared in advance was used to call Ning Xue’s number. If the murderer is a person, he will call with his left hand and answer with his right hand. After the incident, he will return to the fireworks square and throw away Ning Xue’s cell phone; if he still has an accomplice, then he His accomplices were probably in the Fireworks Plaza at the time and acted with him in a play.”

Yu Hanjiang nodded: “Ning Xue’s death time is before 9 o’clock.”

Xiao Lou said with satisfaction: “It seems that Team Yu has already noticed the key points of this case. I believe that with your level, the real murderer will definitely be found.”

Yu Hanjiang glanced at him complicatedly, then turned and left.

Xiao Lou breathed a sigh of relief, lying on the wooden bed, staring at the ceiling thoughtfully.

The murderer’s method of planting and framing is indeed very powerful, but unfortunately, the details of the “traffic control” that night were ignored, and the time difference appeared. Furthermore, the whole process of the crime was too idealistic, and it was easy to cause suspicion.

Now that Xiao Lou has pointed out the key doubts, then it will be up to Tang Ci and this “Yu Hanjiang” to do nothing.

***

After leaving the police force, Tang Ci immediately took a taxi and returned to the company.

Liu Qiao stayed in his laboratory, because Liu Qiao is also a wanted criminal and it is not convenient to show his face. The only relatively safe place he can think of is his own smart laboratory.

To prevent the police from supervising Liu Qiao’s communication equipment, Tang Ci did not contact her along the way.

After returning to the laboratory, Tang Ci found that the entire room was empty. Tang Ci was shocked and hurriedly called out, “Liu Qiao?”

“I am here.”

A familiar girl’s voice came from his ear. Tang Ci turned his head in the direction of the voice and found that Liu Qiao had turned himself into the size of a thumb, lying behind the ear of an intelligent robot. Even if a hunter came to her door, it would be difficult to find her for a while.

Looking at the little girl with big fingers, Tang Ci couldn’t help but curl his mouth: “You can hide.”

Liu Qiao leaped lightly and landed on the table in front of him, and said with concern: “How about the meeting with Professor Xiao? Does he tell you about the next step?”

Tang Ci sat down, turned on his laptop, and typed in a series of web addresses.

Liu Qiao lay down and stared at the computer.

She couldn’t understand the large string of garbled codes that appeared on the screen. She only heard the crackling sound of Tang Ci’s fingers tapping the keyboard quickly. She waited patiently for a moment. Suddenly, the screen lit up and dozens of monitors appeared at the same time. Camera.

The densely packed small monitoring windows give the police the posture of handling cases.

Liu Qiao said in surprise: “You hacked the surveillance system? Where is this surveillance?”

The blue light rays of the notebook shone on the man’s white face, making his skin almost transparent.

While typing on the keyboard, he calmly said: “The surveillance in the conservatory and the medical school next door covers most of the school area. We have to check them one by one.”

Liu Qiao immediately cheered up, changed himself back, and sat next to Tang Ci: “It’s too much, let’s check it separately.”

Tang Ci found another computer, divided half of the video to her, and said, “You came to check the medical school. You are more familiar with the medical school environment than I am. The surveillance near the dissection room of the laboratory building must have been destroyed. But the monitoring on the main road is still there. Look for Zhang Hengyu to see if he has ever appeared in the monitoring.”

Liu Qiao nodded, and began to double fast forward, searching one by one.

Tang Ci is in charge of the video recording of the Conservatory of Music. He first checked the video on the lakeside after 8 o’clock last night-the camera on the lakeside was damaged and it was difficult to take pictures of the students who came; and near the gymnasium, several key cameras would also be destroyed. There are many blind spots that cannot be captured by surveillance.

The murderer was very cunning and prepared in advance at the conservatory.

Tang Ci had to continue to expand the scope of the search.

Balloons, Xiao Lou once mentioned this keyword. At that time, when Xiao Lou and Liu Qiao walked out of the backstage, they saw a person in the corridor leaning over to sort out the remaining balloons.

Tang Ci searched for balloons in all the surveillance, and sure enough, in the surveillance of the “Student Activity Center” building, he found a large number of colorful balloons, which should be the same as the balloons arranged on the scene that night.

At 18:30 in the afternoon, several students rode their bicycles, carrying bags of balloons, banners and other props to the direction of the gymnasium. At the fork in the road to the gymnasium, due to the destruction of surveillance, these people lost their tracks, but when you think about it, they must be the staff who arranged the final venue.

Tang Ci zoomed in on the screen——

That night, all the staff wore a blue sign resembling a “volunteer” on their necks, and most of them wore black clothes. There were a total of 5 staff carrying balloons and banners in the picture. , 3 males and 2 females, they talked and laughed all the way, they should all be students of the Conservatory, and they are very familiar with each other.

Tang Ci called out the surveillance at this fork in the road and checked the video after the event ended at 10 o’clock in the evening——

At 10 o’clock in the evening, the singing competition ended, and a large number of spectators poured out from the gymnasium. Within a few minutes after the event, the instantaneous flow of people was too large, and due to the dim light at night, it was difficult to find clues from the surveillance.

Tang Ci had to zoom in on the monitor screen and watch it every second, not letting go of every frame.

I don’t know how long he watched, just when he felt his eyes were about to go blind, he suddenly saw a figure in the crowd——

That person is not much different from the surrounding students. She is quite tall, over 1.7 meters. She is wearing a long black coat with a hat covering her face. In winter, this kind of dress is not unusual, but Tang Ci noticed that she His clothes are a bit familiar, and he is carrying a large schoolbag behind him.

Comparing the five people who took balloons to the event scene before, he found that the similarity of the clothes reached 100%.

In winter, of course, there are students who wear the same coat, but this person’s clothes have a characteristic-a red balloon that leaked accidentally hung on the clothes line in the lower left corner.

She left alone.

The staff should finish the scene with her companions before leaving. Why did she leave early?

She disappeared at the end of the road destroyed by surveillance, not knowing where she went.

During the surveillance after 10 o’clock in the evening, she was wearing a hat and couldn’t see her face. However, at 6:30 in the afternoon, she and her companions took a balloon with them to the venue, but they happened to have a photo of her face!

Comparing clothes, it is easy to identify which of the 5 people she is.

Tang Ci took a screenshot of this face and entered it into the □□ library of the Conservatory of Music for data comparison, and quickly got the result——

“Chen Mengmeng, 20 years old, a junior in the vocal music department, is in the same class as Ning Xue and lives in the same dormitory.”

Hearing this, Liu Qiao immediately leaned over to look at Xiang Tang Ci’s computer: “Is it a suspect to lock her?”

“Look, in this picture, do you feel familiar with the black coat?” Tang Ci asked.

Liu Qiao recalled for a moment: “I seem to have seen it somewhere… By the way, when Professor Xiao and I came out of the backstage last night, I saw a man squatting in the corner to sort the balloons, but I didn’t see the person’s face clearly. But look at this. Body clothes, it should be her!”

“Professor Xiao suspects that someone has been staring at you secretly. When you walked out of the gym, call Ning Xue to make so-called call evidence.” Tang Ci squinted and looked at the magnified photo in the computer. There was a faint mole in the corner. He said, “The person who is watching you is probably Ning Xue’s roommate Chen Mengmeng, who killed Ning Xue.”

Liu Qiao didn’t have much impression of the three words Chen Mengmeng, but after carefully recalling the police meeting records retelled by Xiao Lou, she suddenly remembered some details: “I remember that Professor Xiao was hiding in the police force at the time and eavesdropped on their meetings. The field team It was mentioned that when visiting the roommates of the deceased, one of them was named Chen Mengmeng. He took the initiative to mention that Ning Xue had two boyfriends. The former was entangled with Ning Xue and clearly reported Ning Xue and Zhang Hengyu. The location of the date last night.”

Tang Ci said, “Then the police found Ning Xue’s bag and mobile phone in the square where they were dating.”

Liu Qiao’s eyes lit up: “In other words, this Chen Mengmeng, intentionally or unintentionally, is guiding the police to find evidence?”

Tang Ci also felt that this possibility was very high. He frowned and thought for a while, and said, “Why would Ning Xue go to the lake alone? Unless someone she trusts asks her to go there, and that person still knows. Which tree by the lake is carved with the names of Ning Xue and Zhang Hengyu, on the whole, the roommates are most likely to be. As for why the mobile phone appeared in the square, it is likely that the murderer killed Ning Xue and got her mobile phone forged After completing the call evidence, since you and Professor Xiao had already gone to the lake at that time, the police would also be there soon. She was afraid to put her mobile phone to the lake, so she had to hide it in her backpack and wait until the concert was over. Lost the phone to the central square.”

The more Liu Qiao thinks about it, the more it makes sense, she then analyzes: “Roommate Xu Mingyue went to the library that night, passing by the lake, the bicycle was punctured, and then Professor Xiao and I screamed; Chen Mengmeng was in the same dormitory. People, I must be very aware of Xu Mingyue’s habit of going to the library every night, so I put nails on the road she was passing by in advance?”

Tang Ci said: “Furthermore, Chen Mengmeng is a staff member of the singer contest that night. He is very close to the lake and can clearly grasp the movement of the lake. If she invites Ning Xue to the lake to chat at 8:30 in the evening, she will push Ning Xue. Go to the lake, take Ning Xue’s mobile phone, and then go back to the backstage and ask her to give her an alibi. The police initially thought that Ning Xue died after 9 o’clock, and Chen Mengmeng’s alibi was actually invalid. She was at 8 p.m. At half past o’clock, I must have used the excuse of’going to the toilet’ to go out once.”

Liu Qiao: “…”

Such a girl hidden in the crowd was almost ignored by them.

Liu Qiao said with a calm face, “Where is the murderer who killed Zhang Hengyu?”

Tang Ci said: “In this world, since we have teammates, there will not be only one hunter, she also has accomplices.”

Liu Qiao turned his laptop 90 degrees and pointed it to Tang Ci: “My monitor, I saw Zhang Hengyu leaving the medical school at 4:30 pm, returning at 9 pm, and heading to the laboratory building. Because of the laboratory building. The surrounding cameras were all destroyed, and no other suspicious targets were seen approaching here.” She couldn’t help but wonder: “How did the murderer get in?”

Tang Ci glanced at the surveillance and said calmly: “The murderer didn’t go in, but never came out.”

Liu Qiao quickly reacted: “You mean, the murderer had been waiting for him in the laboratory building?”

Tang Ci said, “The only way to explain it. Otherwise, what would Zhang Hengyu ran to the laboratory building for at night?”

Liu Qiao followed this line of thought and said: “The person who can let Zhang Hengyu enter the laboratory building unsuspectingly must be someone he trusts. And the one who can stay in the laboratory building without attracting attention should be… from the school. teacher?”

Tang Ci said: “If the teacher asked the students to help with the experiment, the students would naturally not doubt it, especially a class leader like Zhang Hengyu who studies more seriously, maybe he would be proud of it. He and Ning Xue made an appointment to go to the square to watch the fireworks that night. , Why did you come back early? It is very likely that the two had to change their plans after receiving news from someone they trust.”

Liu Qiao frowned and thought about it carefully—she was not familiar with the forensic medicine department, but Professor Xiao seemed to have mentioned that he had an assistant professor?

I remember that at that time, in order to concentrate on investigating the case, Professor Xiao also said that he would let the teaching assistants help him in class, and went to the office to send emails to the teaching assistants…

Liu Qiao reacted abruptly: “Assistant! That assistant often helps Professor Xiao to substitute for lessons. It is easy to get close to Professor Xiao, grasp Professor Xiao’s whereabouts, and steal his phone number card!”

The two looked at each other and stood up immediately.

Tang Ci picked up the car key and turned to go out: “Find these two people as soon as possible. If they run away, Xiao Lou will not be able to clean it.”
