Card Room

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 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 my friend find a good lawyer so soon, are you planning to let this lawyer defend you?"

Xiao Lou looked 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 of them 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 his words.

Tang Ci nodded towards Yu Hanjiang, turned and walked away calmly. Xiao Lou was taken back to Cell No. 1, Yu Hanjiang stood at the door of the cell, looked at him through the bars, and asked, "Did you think of new clues?"

Xiao Lou sat on the wooden bed with a serious expression. "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 records 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 phone, it is inferred that I and Ning Xue Her relationship..." Xiao Lou paused and said with a certain tone "However, these two evidences are not 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 convince 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's calm gaze. He suddenly reacted. "31 At 9 o’clock in the evening, Ning Xue answered the phone, and then came to the lake and was pushed down the lake. The time we received the alarm was around 9:15 in the evening. Her mobile phone was lost in the square. If she was The phone call in the square, then she..."

"Then she has no time to rush back to the scene of the crime." Xiao Lou said calmly, "If it is normal, 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 answer 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.

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 frowning, he obviously understood what he meant. Xiao Lou went on to say, "I'll give Team Yu an analysis. At 9 o'clock, the murderer must have seen me and Liu Qiao at the Conservatory of Music, so he used advance Call Ning Xue’s number with the prepared 136 mobile phone 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 accomplices, then his My comrade, it was very likely that he was in the fireworks square at that time, and he acted in a play with him."

Yu Hanjiang nodded, "Ning Xue's death time is before 9 o'clock."

Xiao Lou gratified and said, "It seems that Team Yu has already noticed the key points of this case. I believe that with your level, the real murderer will 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 methods of framing and framing were indeed very powerful, but unfortunately, they ignored the details of “traffic control” that night, and there was a problem with the time difference. 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, the next step is to see if Tang Ci and this "Yu Hanjiang" can't do much.

After leaving the police, 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, he found that the entire room was empty. Tang Ci's heart was shaken and he hurriedly called "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 a thumb the size of himself, 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? Did 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 while. 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 attitude of handling cases.

Liu Qiao was surprised, "You hacked into the surveillance system? Where is this surveillance?"

The blue light from 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 me. The surveillance near the dissection room of the laboratory building must have been destroyed, but The monitoring on the main road is basically 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, looking one by one.

Tang Ci was in charge of the video 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 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 looked for balloons in all the surveillance, and indeed, 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, a few students rode bicycles, carrying bags of balloons, banners and other props, and headed to the gymnasium. At the fork in the road to the gymnasium, due to the destruction of surveillance, these people lost track, 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 5 staff with 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 up the surveillance at this fork in the road and checked the video after the event ended at 10 p.m.——

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, coupled with the dim light at night, it was difficult to find clues from the surveillance.

Tang Ci had to zoom in on the monitoring 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 going to be 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 tall. She is wearing a long black coat with a hat covering her face. In winter, such a dress is not unusual, but Tang Ci noticed that she His clothes are somewhat familiar, and he is carrying a large schoolbag behind him.

Comparing the five people who had seen the balloons to the event site 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-in the lower left corner of the clothes, accidentally hung a leaking red balloon.

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 clearly, but at 6:30 in the afternoon, she and her companions took a balloon 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 photo, 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 a 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 and overhearing their meetings. The field team used to It was mentioned that when visiting the deceased’s roommates, one of them was named Chen Mengmeng. He took the initiative to mention that Ning Xue had two boyfriends. The predecessor was entangled with Ning Xue and clearly reported that Ning Xue and Zhang Hengyu were yesterday. Location for late appointments."

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 guiding the police to find evidence?"

Tang Ci also felt that this possibility was very high. He frowned and thought about it, "Why would Ning Xue go to the lake alone? Unless someone she trusts asks her to go, and that person knows the lake. Which tree next to the tree engraved the names of Ning Xue and Zhang Hengyu, on the whole, the roommates are the most likely. 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 the call evidence, because you and Professor Xiao had already gone to the lake at that time, the police would arrive soon. She didn't dare to put her mobile phone to the lake, so she had to hide it in her backpack and waited for the concert to end. Throw it to the central square."

The more Liu Qiao thought about it, the more it made sense. She then analyzed, "My 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 a person in the same dormitory. , I must be very clear about Xu Mingyue’s habit of going to the library every night, so I put nails on the road she passed 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 to the lake. In the lake, I took Ning Xue’s mobile phone and went back to the backstage and asked 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 o’clock in the evening. Half, 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 calmly said, "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 the laptop 90 degrees and pointed it to Tang Ci, "My monitor, I saw Zhang Hengyu leaving the medical school at 4:30 pm, coming back at 9 pm, and heading to the laboratory building. Because of the surroundings of the laboratory building. All of his cameras were 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 calmly said, "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 rush to the laboratory building to do 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... the school teacher ?"

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

Liu Qiao frowned and thought about it carefully—she is not familiar with the forensic medicine department, but Professor Xiao seems to have mentioned that he has 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 assistants...

Liu Qiao reacted suddenly, "Teacher assistant! That assistant teacher often substitutes for Professor Xiao, so he can easily get close to Professor Xiao, grasp Professor Xiao's whereabouts, and steal his phone number card!"

The two looked at each other and immediately stood up.

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."
