"Be quiet, comrades. Next, we will conduct a brief case analysis meeting. Lao Song, let's start with you, and introduce the situation of the technical team's on-site inspection to everyone."
"Okay, Team Lee."
Song Zhe got up and walked to the projector screen, operating the computer and speaking to the crowd: "From the results of our technical team's investigation, the roof of the dormitory where the victim was located was the first murder scene. We found it on the roof. The victim's suitcase, the suitcase has been burned by the murderer, and from the ashes we found a piece of cloth with blood, which was tested to match the blood type of the deceased."
Song Zhe pointed to a photo and continued: "We also found traces of climbing in this corner of the rooftop, presumably the murderer climbed up and down the rooftop along the sewer pipe here, but given the surrounding No surveillance was installed, so the killer's climb was not recorded."
"From the surveillance video of the victim Xu Yuanyuan and the criminal suspect Yang Biao, we can judge that the time of the deceased's murder was between 1:33 and 4:30 in the morning. Cloth, we found that the quality of this piece of cloth is the same as the clothes Yang Biao wore before he left the dormitory. It may be the murderer who killed Xu Yuanyuan!"
After Song Zhe finished speaking, Li Meilin turned her eyes to Mao Zheqiang and said, "Forensic doctor Mao, talk about it too!"
Mao Zhuqiang nodded and signaled to the crowd, "After examining the victim's body, it can be determined that the fatal injury of the deceased was caused by the instant cutting off of the head, and the removal of the ten fingers was done after the deceased's death, presumably the deceased's nails. The murderer's skin fibers and other criminal evidence remained in the seam. The milky white liquid extracted from the lower body of the deceased, after DNA testing, was consistent with the DNA of the criminal suspect Yang Biao."
"Because the murderer severely damaged the body of the deceased with knives, and the internal organs were also damaged to varying degrees, it is impossible to accurately determine the time of death of the deceased through liver temperature and corpse temperature. Just now, Section Chief Song has confirmed it through surveillance video. As for the time when the victim Xu Yuanyuan was killed, I don't think it is necessary to do a detailed test for the specific time of death."
Li Meilin nodded, her eyes fell on my face, and she asked, "Do you have anything to say?"
I shook my head: "No!"
Li Meilin retracted her gaze, looked around the crowd, and concluded: "At present, all the clues point to Yang Biao, but we have not found the head of the deceased and the murder weapon. For the next task, we will continue to expand the scope while interrogating Yang Biao. , to search for the victim's head and the murder weapon with all his strength. This short meeting is here, disbanded!"
At noon, I tossed and turned in bed, unable to sleep, thinking about the murder in my head.
Although all the clues point to Yang Biao, in my heart, I don't think he is the murderer of Xu Yuanyuan. There are too many suspicious points in this case.
If the murderer is one of Yang Biao's roommates, then the clothes he wore before committing the crime can be confirmed to have been burned, but why can't the clothes that the murderer wear back after the crime be found? Could it be that the murderer had secretly hid his clothes before we found Yang Biao
I felt like my brain was getting bigger and bigger, and finally I fell into a drowsy sleep. I don't know how long it took, I was woken up again by the ringing of my phone, and I couldn't help but curse in my heart.
"Where are you?" As soon as the phone was connected, Li Meilin asked.
"Bedroom."
"What are you doing in the bedroom?"
"sleep."
The other end of the phone was obviously silent for a while, and then Li Meilin's dissatisfied voice came again: "The head was not found, and the murder weapon was not found. How can you have time to sleep?"
I thought what Li Meilin said was very funny, so I sarcastically went back: "Why can't I have time to sleep? My lord, I don't have much, just a lot of time."
"you… "
"What are you? You're a policeman, but I'm not. It's your duty to handle a case, and I'm not an obligation at best."
"You have kind of..."
"I don't have any seeds, do you have them? It's been a few months? Which man's?"
The call was suddenly interrupted, and the corners of my mouth raised proudly while lying on the bed. Although she couldn't see Li Meilin's violent rage, she could imagine the funny appearance of her holding the phone and trying to keep it from falling.
I had no intention of continuing to sleep, so I decided to go to Yang Biao's bedroom again to see if I could find any new clues.
On the way to Yang Biao's dormitory, when I thought of the unpleasant smell of cigarette smoke mixed with the smell of stinky feet, I had lingering fears, and I couldn't help feeling the urge to strangle myself. I'm not a policeman, isn't this enough to make me feel guilty
But if I don't help the police solve this murder case, how can that sturdy woman Li Meilin let me live in peace in the future
During the repeated struggles in my heart, I came to Yang Biao's bedroom unknowingly. At this time, only Li Qiang was playing games alone in the dormitory, and the other two did not know where they went.
"This police uncle... uh... brother police officer, if you have any questions, just ask me directly. We are a family of police and civilians. If I knew anything, I would definitely tell the truth."
Looking at Li Qiang's serious face in front of me, I explained with a bit of a laugh, "I'm not a policeman."
"What? You're not a policeman?" Li Qiang looked at me in surprise, then asked, "Then who are you?"
I smiled and said, "I'm a detective and I'm currently assisting the police with this murder."
"I'm going! It turns out that you are a detective, so do you know my idols Sherlock Holmes and Conan?" It can be seen that Li Qiang at this time was obviously relieved after knowing that I was not a policeman. joke.
"I don't know them, but I know that in the near future, my name will appear in your idol." I paused for a while, and my expression became serious, "Remember my name, my name is Luo Chao. "
"Hahaha... I give full marks to this pretending!" Li Qiang suddenly burst into laughter, and after laughing, he introduced himself, "My name is Li Qiang, nice to meet you."
I followed with a smile and said, "I know your name is Li Qiang."
"Ah? How did you know?" Li Qiang looked at me in amazement, with a rather comical look of surprise.
"I've said it before, my name will appear in your idols in the near future. If I don't even have the ability to reason, how can I dare to say that out loud?" I grinned at him. , leaked out his mouth full of white teeth, and asked him narrowly, "Do you think so? My future fan classmate."
"I'll go! Isn't it? Is it really that awesome?"
Looking at Li Qiang's confused and funny face, I laughed without saying a word.
In fact, where did I deduce it? This is obviously because Yang Biao's other two roommates mentioned his name in the morning. The truth is that simple.
After chatting for a while with Li Qiang, we got to the point: "I want to know what Xu Yuanyuan did in your dormitory last night?"
Seeing that my expression suddenly became serious, Li Qiang also put aside his playfulness, thought about it and said, "I didn't do anything, just stayed in our dormitory for a few minutes and left. I was still very puzzled at the time, Xu Yuanyuan used to be When you come to our dormitory, you will kiss me with Yang Biao and I will show your affection before leaving."
"When she left, did Xu Yuanyuan take Yang Biao's clothes and said she wanted to help him wash them?"
"I really didn't pay attention to this, but Xu Yuanyuan used to help Yang Biao wash clothes in our dormitory."
According to what Li Qiang said, then the problem arises. In the past, Xu Yuanyuan and Yang Biaoxiu would only leave after a lot of love, but last night, they only stayed for a few minutes and left. Could it be because of the unpleasant smell in the bedroom? Smoked away
Also, Xu Yuanyuan used to help Yang Biao wash his clothes in his dormitory, so why did she take Yang Biao's clothes back to the dormitory to wash them last night
I asked again: "How is the relationship between Yang Biao and Xu Yuanyuan? Have there been any conflicts between the two recently?"
"The relationship between the two of them has always been very good. Xu Yuanyuan has always been a little bird in front of Yang Biao, and although Yang Biao usually has a machismo, he loves Xu Yuanyuan very much..."
From Li Qiang's words, I concluded that Yang Biao and Xu Yuanyuan are a very loving couple. It is not difficult to see that Xu Yuanyuan often does laundry for Yang Biao.
So Xu Yuanyuan used to wash Yang Biao's clothes in his dormitory before, why did she take his clothes back to her dormitory before she was killed? Is this a coincidence
I observed in Yang Biao's bedroom, and then went to the balcony to have a look. There is no sewer pipe on the wall near the balcony, but it is only more than one meter wide from the balcony of the bedroom on the left and right sides. This distance is generally enough for adults to cross.
This time I have new doubts? Could it be that the fake 'Yang Biao' did not belong to this dormitory, but someone else
However, I checked carefully on the balcony and found no traces of overturning. The doubts in my heart became more and more, and this case seemed to be more complicated than I imagined.
When I was about to say goodbye to Li Qiang and leave, Yang Biao's other two roommates came back together. I endured the suffocating discomfort and talked to the two of them, and what they said about the relationship between Yang Biao and Xu Yuanyuan The matter is generally consistent with what Li Qiang said.
"Luo Chao, I don't think Yang Biao could have killed Xu Yuanyuan." The person who spoke was Zhao Jie.
I asked curiously, "Why do you say that?"
"Yang Biao will take Xu Yuanyuan to open a room every Friday. They have had many relationships long ago. There is no need for him to rape and kill her."
Going to an open house every Friday? And Xu Yuanyuan was killed in the early hours of Saturday morning, so if the semen in her body belonged to Yang Biao, it might have been left in her body when the two had a room.
"Don't worry, I'm investigating this matter to reveal the truth. If the murderer is really not Yang Biao, the police will definitely not wrong him, and they will let him back."
After I came out of Yang Biao's bedroom, I took a deep breath in the corridor for the first time. Even though I had practiced holding my breath under deep water, I couldn't bear to stay in such a bad-smelling bedroom for a long time.
Feeling the turbid gas in my lungs swept away, I took a step forward and went to the monitoring room again. If the murderer is one of Yang Biao's roommates, then I'd like to see who left the dormitory before we found Yang Biao.
I carefully checked the surveillance video and found that when the fake 'Yang Biao' returned to the dormitory to find him, no one left at all during this period.
So where did the clothes that the fake 'Yang Biao' wore back go
Could it be that the fake 'Yang Biao' was not someone in their dormitory, but someone else. This person did not leave the slightest trace when he climbed over the balcony, or he cleverly erased the trace left when he climbed over, and deliberately created this fake 'Yang Biao' as an illusion that someone in their dormitory
This possibility also exists.
I retrieved the surveillance footage of Xu Yuanyuan going to Yang Biao to get her clothes and watched it several times, but I didn't find anything unusual. But I always felt that there must be a link that I had overlooked, so I continued to retrieve the previous surveillance footage of Yang Biao for repeated comparisons, and the result really made me see a little tricky.
After leaving the boys' dormitory building, I went to the monitoring room of the girls' dormitory building again. I retrieved and compared the surveillance footage of Xu Yuanyuan in the past two days. As a result, I found important clues again.
It was past six o'clock in the afternoon when I came out of the girls' dormitory building, so I called Li Meilin and asked where she was? She said she was going to get off work and asked me what was the call
I immediately sneered: "The head has not been found, and the murder weapon has not been found. How can you get off work?"
"It's none of your business if I get off work or not!"
Listening to her words with a strong smell of gunpowder, I didn't get angry at all, and said to her, "Yes, yes, it doesn't matter to the young master, the young master will use the weekend break to help you investigate when he is full. Clue. In that case, hang up."
"you dare!"
"Why don't I dare?"
"If you dare, I will go to your dormitory immediately and break your third leg." Li Meilin viciously threatened me.
"Haha... My third leg will definitely not be used by you, sir. You should go buy bananas, eggplants and other things." After that, I hung up the phone.
Li Meilin called me again, and I refused to pick up. She called again, I refused to pick up again, and it went on and on for five times before I connected.
"Where are you now, I'll go look for you." Li Meilin's tone was obviously much gentler.
I held my phone and grinned proudly, with the face of a villain: "I'm having dinner at Shilixiang, are you sure you want to come?"
"Why did you run there to eat? Did you make a fortune?"
"Have you made a fortune? It's because I found a major clue during the afternoon investigation. I'm going to treat myself." I know that Li Meilin understands what I mean, and even if she is upset, she will come to pay for me.
"You wait there, I'll be there in about half an hour."
"That's fine, you also know that I don't like people being late, so you can control the time yourself. If I leave first because of your lateness, don't call me again."
"Why are you talking so much! And I don't know when you got this kind of problem?"
"Hey! Just got it!"
After hanging up the phone, the corners of my mouth almost reached the lobes of my ears, and I hummed proudly: "Master, if I can't even clean up with you, then I'll have an extra leg than a woman for nothing."
