The surveillance footage from the boys' dormitory showed that Yang Biao had left the dormitory at one o'clock in the morning, and returned to the dormitory with a tired look at 4:30 in the morning.
So where did he go during those three and a half hours? What did you do? And this time period is exactly the time when Xu Yuanyuan was killed. What is the relationship between the two
After watching the surveillance video, Yang Biao was dumbfounded on the spot, and muttered to himself, "How is this possible? I slept in the bedroom all night."
Li Meilin stared at Yang Biao with a cold expression, her cold eyes seemed to be able to cut him with a thousand swords at any time, and it seemed that she had already determined that Yang Biao was the murderer.
"Tell me, where did you leave the dormitory in the middle of the night? What did you do during this time?"
Faced with Li Meilin's sharp questioning, Yang Biao shook his head vigorously in denial: "I slept in the dormitory last night and never left!"
Li Meilin sneered, with a little more disdain in her expression: "Is it you who was photographed on the surveillance camera?"
Yang Biao nodded and shook his head: "It's me, but it's not me."
"Yes, yes, no, no, what is yes and no? You are playing with me!" Li Meilin's voice suddenly increased by an octave, obviously very dissatisfied with Yang Biao's answer.
"Although the person in the video looks like me, it's not me. Because I slept in the bedroom last night and never left. If you don't believe me, you can ask my three roommates."
"Xiao Wang, go and call me his three roommates." Li Meilin turned her eyes and ordered a police officer behind her.
Xiao Wang's name is Wang Jun. He is an intern. If he performs well during the internship, he is very likely to stay in the Criminal Investigation Detachment after graduation. In Li Meilin's heart, it was a solid seven-point respect and three-point fear!
"Yes! Team Li." Wang Jun led the way, without any delay in his words and deeds.
Not long after, Yang Biao's three roommates were taken to the surveillance room. Li Meilin first let them watch the surveillance video before asking, "Did any of you three see Yang Biao leave the dormitory last night?"
The three shook their heads and said no.
"The three of you live in the same dormitory as Yang Biao, how could it be possible that no one saw him leave? It's impossible for all three of you to sleep so deeply, right? No one even went in or out of the dormitory. Did you find out alone? Or are you trying to cover up?" At the end of her speech, Li Meilin's tone became more severe, and her eyes became extremely cold.
Facing Li Meilin's aggressive words, one of the dark-skinned boys thought about it and said, "Yang Biao must have been in the dormitory before I fell asleep last night. As for whether he left the dormitory in the middle of the night, I don't know, because I am I slept until you knocked on our bedroom door and woke up."
Li Meilin's lips curled slightly, and her burning eyes turned to the other two boys: "What about you two?"
"Like Li Qiang, we only woke up after you knocked on the door of our dormitory." The two boys said in unison, and looked at each other, as if they were nodding to each other's tacit understanding. awesome.
Li Meilin raised her eyebrows lightly: "That is to say, you only saw Yang Biao in the dormitory before falling asleep. As for whether he left the dormitory in the middle of the night, I don't know?"
"Yes!" The two nodded in agreement.
Seeing his roommate say this, Yang Biao's eyes immediately turned red: "You guys..."
"Shut up!" Li Meilin interrupted him with a loud shout, glaring at him, "What else do you have to say now?"
"I... I... " Yang Biao squeaked and hummed for me for a long time without me coming out with you and me.
Li Meilin's expression was cold, and her eyes were a little more indifferent: "They can't prove that you slept in the dormitory all night, but the surveillance took a picture of you leaving the dormitory in the middle of the night. How do you explain this? You keep saying that in the video The boy is you but not you? Could it be that you are possessed by a ghost? How can you tell a lie with peace of mind?"
"I didn't lie, I really slept in the dormitory all night. As for why the surveillance took a picture of me leaving the dormitory, I don't understand." Yang Biao still firmly denied it, shaking his head with a rattle It seems.
"Can't you understand? Well, I'll help you think about it." Li Meilin stared at Yang Biao coldly, "At one o'clock in the morning, you quietly left the dormitory after your roommates were asleep, and then asked Xu Yuanyuan to go to the roof of their dormitory. On the rooftop, he was brutally murdered on the rooftop."
"No! It's not like that!" Yang Biao was a little mad, glaring at Li Meilin with red eyes, "I didn't kill anyone, the person in the video looks like me but not me. And Xu Yuanyuan is my girlfriend, why should I kill her?"
Li Meilin snorted coldly: "It doesn't matter if you don't admit it. After the DNA test results come out, let's see how you can quibble!"
"If that's the case, why are you still talking nonsense to me here! When you find the evidence, won't you just sentence me to prison?" Yang Biao's face was a bit hideous because of his anger, and his voice was louder than before. .
Standing behind Li Meilin, what I saw in Yang Biao's eyes was pain and anger, I don't think he should lie. If Yang Biao can still perform like this after killing people, then his acting skills can be used as a movie king in the entertainment industry.
Judging from the murderer's method of destroying the corpse and destroying the traces, the other party should be a careful and careful person, and basically no valuable evidence was left at the scene, indicating that the other party's anti-reconnaissance ability is extremely strong.
Then it is such a murderer with superb criminal methods. Leaving semen on the lower body of the deceased seems incompatible with the thinking of destroying corpses and destroying traces.
Furthermore, if the murderer is really Yang Biao, it means that he went to the rooftop of the girls' dormitory to meet Xu Yuanyuan last night. Since he could secretly enter the rooftop of the girls' dormitory, how could he easily reveal his whereabouts in the boys' dormitory
No way to explain this.
There is one thing I don't understand. Even if Yang Biao left the dormitory in the middle of the night, he is still not sure that he is the murderer of Xu Yuanyuan. Why did Li Meilin simply believe that Yang Biao was the murderer of Xu Yuanyuan? Her anomaly really left me a little puzzled.
"Think about it again, what's the difference between the 'you' in the video and you?" I suddenly interrupted and asked Yang Biao.
I think if the person in the video is really Yang Biao, he shouldn't admit it so deadly in front of the facts, there must be something we ignore.
Yang Biao looked at me strangely, then frowned, recalling it carefully.
He suddenly slapped his thigh and said a little excitedly: "I remembered that the clothes 'I' was wearing in the video were the ones Yuanyuan took to their dormitory to wash for me last night."
I asked Zhang Hongwei to replay the surveillance video again, and as a result, I made a new discovery: in the video, the clothes 'Yang Biao' wore when he left were different from the clothes he wore when he came back.
Previously, all of us only noticed that the person in the video was 'Yang Biao', but ignored the clothes he was wearing. After his reminder, I suddenly remembered that the cloth in the ashes was the same color as the clothes 'Yang Biao' wore when he left the dormitory in the video.
Then it can be explained that the 'Yang Biao' who walked out of the dormitory went to meet Xu Yuanyuan, killed her, and returned to the dormitory wearing the clothes of Yang Biao that Xu Yuanyuan took away.
Since 'Yang Biao' in the surveillance video walked out of their dormitory in the middle of the night and finally returned to the dormitory, then excluding the case that Yang Biao was not the murderer, another possibility is that the murderer was actually one of his three roommates. a certain one.
Let's assume that one of Yang Biao's roommates pretended to be Yang Biao, left the dormitory and went to the rooftop of the girls' dormitory, tricked Xu Yuanyuan to the rooftop and wanted to have sex with her or had already had sex. As a result, for some unknown reason, he was found out, and finally he was forced to kill people and destroy the corpses and traces.
But there are a few points that make no sense in this assumption. If the semen in Xu Yuanyuan's body was the murderer's, why didn't he dispose of the semen in the corpse after the corpse was destroyed
Also, if the murderer simply pretended to be Yang Biao to seduce Xu Yuanyuan, then after his identity was revealed, he had no choice but to kill Xu Yuanyuan. Where did the weapon for dismembering his body come from? It can be seen from the video that 'Yang Biao' left the dormitory without a backpack at all.
In other words, the murder of Xu Yuanyuan was actually premeditated. The murder weapon was hidden somewhere in advance, and there was no plan for Xu Yuanyuan to survive from the beginning.
There is another possibility, that is, the murderer killed Xu Yuanyuan, and its ultimate purpose is to put the blame on Yang Biao.
These questions were difficult to understand for a while, so I had to put them aside for the time being, and asked Yang Biao again, "Where are the clothes 'you' wore in the video? And can you show us your cell phone?"
Since the murderer walked out of the bedroom disguised as Yang Biao, he may have used Yang Biao's mobile phone to communicate with Xu Yuanyuan. I think there should be some clues from clothes or mobile phones.
"The clothes were gone when I woke up." Yang Biao touched his pocket again, "The phone is also gone, why don't you wait a moment and I'll go back to the dormitory and look for it?"
Before I could express my opinion, Li Meilin spoke first: "Xiao Wang, follow him to prevent him from fleeing in fear of crime."
Regarding Li Meilin's decision, I have nothing to say. Her concerns are justified. At least all the clues at present point to Yang Biao. Even if he is not the murderer, he is now a criminal suspect.
I reminded again: "You can send someone to visit Xu Yuanyuan's bedroom and see if you can find her mobile phone?"
Li Meilin nodded and instructed Li Shengnan, who called for the surveillance, "Shengnan, please go to Xu Yuanyuan's bedroom."
"Okay, Team Lee."
After Li Shengnan left, in order to ease the stiff atmosphere, I joked: "Why do you think Shengnan's parents gave her such a name? Is it because she gave birth to a daughter and wanted to use her as a boy? I even hope that she is more powerful than the boy, so she is named Shengnan!"
Zhang Hongwei turned his head to look at me, and said with a smile: "Luo Chao, I think your analysis is very reasonable." He glanced at Li Meilin who was beside him, "What do you think, Team Li?"
Li Meilin glared with beautiful eyes, and said in a firm tone: "I think you two are really boring! It seems that the workload is too little!"
Zhang Hongwei shrank his neck in fright, silently turned his head back and stopped talking. Seeing that Li Meilin was so incomprehensible, I simply shut my mouth and stopped talking, so as not to spray me again in a while.
After Wang Jun came back, he shook his head at Li Meilin: "Li team, I didn't find it."
About ten minutes later, Li Shengnan also hurried back, but he found nothing.
The clothes and mobile phone just disappeared, just like the head and ten fingers of the victim who were cut off by the murderer, nowhere to be found.
Although it is not yet completely certain that Yang Biao is the murderer, all the clues that the police have at present point to him, so in the end, the police temporarily detained Yang Biao as a criminal suspect, pending further investigation.
