[Not Guilty Defense-08]
The deaths of Xie Xiangqin and Liu Jiajia did not cause much disturbance in the school. The school clearly controlled the spread of public opinion. There was no discussion on the matter on campus, and only 6 girls' dormitories whispered in private.
Qin Miao has heard many people's opinions on this matter. Most of the girls think that Liu Jiajia accidentally drowned in the sea, and Xie Xiangqin was stabbed to death by her roommate Zhu Xiaoting.
Qin Miao also personally contacted several key suspects.
Xu Youyou, who went out to the 811 dormitory in the morning, is very fond of gossip. Whenever anyone asks her what happened in the morning, she is willing to tell her experience vividly: "I got up at 5:30 this morning to go to the toilet, and I heard a voice from downstairs. With a scream, I hurriedly went downstairs to have a look, only to see Xie Xiangqin in dormitory 703 lying in blood, and Zhu Xiaoting with a knife in her hand."
Qin Miao asked her, "Are you familiar with Xie Xiangqin and Zhu Xiaoting?"
Xu Youyou said mysteriously: "I'm familiar with Zhu Xiaoting. I know that she has a crush on their professional junior brother Zou Yijia, but Xie Xiangqin took the initiative to chase after Zou Yijia. Zhu Xiaoting may have done it because of her psychological imbalance. Alas, girls are really jealous. It's terrible, killing a man for a man is really not worth it!"
Qin Miao looked at her expression carefully, Xu Youyou didn't show any guilty conscience, she had a "passers-by gossip" attitude, if she was the murderer, then her acting skills were too good.
Qin Miao asked, "Did you see anyone else in the corridor when you went downstairs this morning?"
Xu Youyou thought for a while and said, "Most people were sleeping at 5:30 in the morning, and there was no one in the corridor. When I ran downstairs, I saw several dormitories on the 7th floor open, and people came out to check the situation. On the 8th floor, You seem to be the only one going down?"
Qin Miao said: "Yes, I was woken up by a scream and went downstairs to see it. Is there anyone above the 8th floor?"
Xu Youyou nodded seriously: "It shouldn't be. But I went down the stairs from the west, I don't know about the east."
After chatting with her, Qin Miao went to find Wang Xiaolu in the 812 dormitory.
Wang Xiaolu was very cold, and when Qin Miao asked her, her attitude was not very friendly, she just said coldly: "I'm sleeping in the dormitory, I don't know what happened in the morning. Xie Xiangqin and Zhu Xiaoting, I'm not familiar with them, you can go find them. Let others ask."
After she said that, she closed the dormitory door directly.
Qin Miao touched her nose, and there was no reason to continue talking to her.
The girls' dormitory building is a long structure with 25 dormitories on each floor. The dormitory is oriented north-south. There are stairs and elevators on the east and west sides. Girls can choose the stairs and elevators that are closer to their dormitory to go up and down the stairs.
Qin Lu drew a map of the dormitory distribution on the paper and sent it to the group: "The dormitory building is a rectangle, with elevators and stairs on both sides of the east and west sides. No. 01-12 dormitories on each floor are closer to the stairs and elevators on the west side. No. 13 Located in the middle, dormitories 14-25 are closer to the east. The deceased, Xie Xiangqin, lives in 703, which is to the west. Suspects Xu Youyou of 811 and Wang Xiaolu of 812 are also closer to the west."
Yue Xingwen looked at the distribution map carefully and said: "So, their dormitory is closer to the west, so when they go downstairs, they will choose the stairs and elevators in the west out of habit?"
Qin Lu said: "Yes. I visited around, and when I heard the movement, the people who went to watch were the people in the dormitory next to 703, and the people on the 8th floor that were closer to them. In the dormitory on the east side, many people did not hear the screams. , and some people didn't join in the fun even if they heard it. There were a total of 5 people who came to the scene in the morning, the witness Mao Yue, me, Xu Youyou from 811, and two girls in the dormitory next to 703. "
Yue Xingwen carefully sorted out the timeline of the dormitory murder case—
"Around 5:20, the murderer stabbed Xie Xiangqin in the 703 dormitory, found Zhu Xiaoting coming downstairs, and used Xie Xiangqin's mobile phone to call Zhu Xiaoting. Through the illusion of words."
"At 5:21, the murderer sent Zhu Xiaoting a WeChat message 'We should have a break', and left a WeChat record on Zhu Xiaoting's mobile phone to further frame the blame."
"At 5:25, Zhu Xiaoting took the elevator upstairs and opened the door to enter the dormitory. At this time, the murderer had already fled, leaving only Xie Xiangqin, who was still breathing in a pool of blood. Zhu Xiaoting went to rescue people in panic and encountered the murder weapon."
"At 5:28, Mao Yue returned to the dormitory and witnessed the scene of Zhu Xiaoting holding a knife, screaming loudly to wake up the others."
"At 5:30, Qin Miao, Xu Youyou and others who heard the screams ran to the door of the 703 dormitory and called the police."
Time is very tight, once the murderer does not run in time, it is easy to hit Zhu Xiaoting who is going upstairs.
The entire corridor of the girls' dormitory is about 50 meters long. Since the 703 dormitory is located at the west end, it is only 6 meters away from the stairs on the west side and 44 meters from the stairs on the east side. She ran halfway, and once Zhu Xiaoting's elevator reached the 7th floor, as soon as the door opened, she would see her hurriedly running away.
This is also the reason why Zhu Xiaoting heard footsteps in the stairwell after taking the elevator to stop on the 7th floor—
At the time, the killer had just escaped from the west stairs.
There are two possibilities for her to run upstairs. One is that her dormitory is upstairs, and it is safe to run back to the dormitory; the other is that she wants to go upstairs to hide first, to create an illusion for Zhu Xiaoting, and then take advantage of the chaos. building.
If the murderer is a medical school girl who lives on the 8th floor, he can fully meet the conditions for committing the crime.
Xu Youyou's gossiping behavior is not like the murderer, but it does not rule out that her acting is top-notch, and she deliberately spreads rumors of Zhu Xiaoting's murder; Wang Xiaolu's attitude is indifferent, she only says that she is sleeping in the dormitory and doesn't know what happened.
Since the monitoring of the corridors of the girls' dormitory happened to be broken these days, the suspicion of both of them could not be ruled out.
It also depends on who has the key to 703.
At this time, Jiang Pingce, Ke Shaobin and Xin Yan had just walked out of the school gate and were investigating the surrounding area.
They found a supermarket at the entrance of the school, bought a bag of tissues, and asked the cashier at the front desk, "Is there a place around where you can get a key? I lost my dormitory key, so I'll go get one with my roommate."
Ke Shaobin has a good attitude and smiles all over his face. The cashier girl quickly pointed to the right: "Go ahead, turn right ten meters, there is a hardware store that can be equipped with keys."
Jiang Pingce asked, "Is this the only store?"
The girl nodded: "This one is near the school!"
Ke Shaobin thanked him, and the three walked around the corner side by side. Sure enough, they saw a hardware store. A middle-aged man was busy in the store. Some students were looking for him to buy nails. a bit.
The boss smiled and seemed to have a good temper. After the two students left, Jiang Pingce took a step forward.
Xin Yan asked, "Boss, can you get a key here?"
Boss: "Okay, what kind of key do you want?"
Xin Yan took out a key from his pocket: "It's this kind of key for the school dormitory. My roommate accidentally lost the key, so I gave him a key." Then he looked at Ke Shaobin.
Ke Shaobin immediately cooperated with him in acting: "Hey, maybe he fell in the gym yesterday while changing clothes. Boss, how much does it cost for a key?"
The boss took the key and glanced at it, and said, "This kind of thing? 10 yuan."
Jiang Pingce suddenly asked in a low voice, "If I used plasticine to get the key mold, can you match it here?"
Ke Shaobin looked at Jiang Pingce in surprise.
The latter looked indifferent and looked at the boss calmly.
The boss smiled and said, "Young man, are you questioning me? Of course you can match it if you have a mold! The key is originally made from a mold. Why, you lost your key too?"
Jiang Pingce said lightly: "It wasn't me, it was my friend who lost the key to the laboratory a few days ago. I was afraid that the teacher would scold him. I plan to use the spare key to get a mold next time I do the experiment. Give it back to the teacher."
The boss said: "No problem, you can bring the mold! Some students have done this before. If there is a mold, I can make it for you in 10 minutes."
Xin Yan and Ke Shaobin: "..."
Ke Shaobin excitedly pulled out a photo from his mobile phone and asked, "Boss, is this classmate who took the mold and the key?"
The boss shook his head: "No."
Ke Shaobin continued to scroll back: "Where's this one?"
The boss continued to shake his head: "No. Alas, you students lose their keys at every turn. There are so many people who come to me with keys. How can I remember them clearly!"
Just when Ke Shaobin turned to the fifth photo, the boss's eyes suddenly lit up: "It seems to be this classmate! Wearing glasses, the gentleman, yes, it's him!"
Ke Shaobin confirmed: "Chen Kaiming from the School of Chemistry?"
The boss laughed: "I don't know what his name is. Anyway, he lost his key and came to me with a mold."
Xin Yan whispered in Ke Shaobin's ear: "Continue to ask about the girl's situation."
Ke Shaobin quickly pulled out the photos of Xu Youyou and Wang Xiaolu from his mobile phone: "Have these two girls asked you for keys?"
"No!" The boss thought about it carefully, then nodded firmly: "I'm sure not."
"What about her?" Jiang Pingce suddenly recalled the photo of the deceased Xie Xiangqin from his mobile phone.
"Hey? This girl seems to be here! She came with her boyfriend. I remember very clearly. She also complained that her boyfriend accidentally lost her keys..." The boss scratched his head, "By the way, you ask these questions. What are you doing?"
"It's nothing, these are my classmates. They introduced you to get the keys here." Jiang Pingce calmly put away his phone.
"Give us one, and get it later." Xin Yan left a key and 10 yuan, and the three turned to leave.
After returning to the dormitory, Jiang Pingce asked in a low voice, "Ke Shaobin, have you recorded it?"
Ke Shaobin took out the small picture from his pocket and said, "The small picture has been recorded!"
After the small picture is upgraded, it can record and video, and monitor a designated area within a certain period of time. Its body grows to the waist of Ke Shaobin, but it can also retract to the original palm size for easy portability, turning it into a mini robot.
During the investigation just now, Ke Shaobin recorded the whole process so that it can be used as evidence in the future.
He uploaded the recording of Xiaotu to his laptop and then to the WeChat group.
After listening to the recording, Yue Xingwen couldn't help but send a thumbs up: "The information from Pingce is very important, someone from the School of Chemistry has assigned the key to the laboratory! This person is probably related to Liu Jiajia's death, he can go to Potassium cyanide was obtained in the laboratory. In addition, Xie Xiangqin once lost the key and went to match with her boyfriend. "
Lan Yarong analyzed: "So, the murderer who killed Xie Xiangqin didn't get a key to the 703 dormitory, but took the key that Xie Xiangqin lost?"
Xie Xiangqin lost the key, this clue is very important!
Lin Manluo followed this line of thought and said, "The boss said that the key was lost by her boyfriend. Could the murderer be related to her boyfriend, or that her boyfriend is actually suspected?!"
Yue Xingwen suddenly said: "Do you think that the murderer who killed Xie Xiangqin must be a girl?"
When people died in the girls' dormitory, everyone's first reaction was that girls did it. After all, boys couldn't get in. But…
Ke Shaobin's mind flashed: "Is there a problem with the access control of the 6 girls' dormitories? Zhu Xiaoting and Mao Yue can go back to the dormitory at 5 in the morning, so is it possible for boys to sneak into the dormitory? The door of the dormitory is not locked? "
Qin Miao replied: "Yes, the access control and monitoring of the 6 dormitories have just broken down in the past two days and are being repaired."
