Escape From the Library

【Innocence Defense-08】

The deaths of Xie Xiangqin and Liu Jiajia did not cause much disturbance in the school. The school obviously controlled the spread of public opinion. There was no discussion about this matter on campus, only the 6 girls' dormitories whispered privately.

Qin Miao listened to many people's opinions on this matter. Most of the girls believed that Liu Jiajia drowned in the sea accidentally, 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 in the 811 dormitory in the morning, is very gossipy. As long as someone asks her what happened in the morning, she is willing to tell her experience vividly: "I got up at 05:30 this morning to go to the toilet. There was a scream, and I hurried downstairs to look, only to see Xie Xiangqin in dormitory 703 lying in blood, and Zhu Xiaoting holding a knife in his hand."

Qin Miao asked her: "Are you familiar with Xie Xiangqin and Zhu Xiaoting?"

Xu Youyou said mysteriously: "I'm close to Zhu Xiaoting. I know that she has a crush on their professional junior brother Zou Yijia. As a result, Xie Xiangqin took the initiative to chase after Zou Yijia. Zhu Xiaoting may have done it because of her mental imbalance. Alas, the jealousy of girls is really true." It's terrible, it's really not worth killing for a man!"

Qin Miao carefully looked at her expression, Xu Youyou didn't show the slightest guilty conscience, she had an attitude of "passers-by gossip". If she is the murderer, then her acting skills are too good.

Qin Miao asked, "When you went downstairs this morning, did you see anyone else in the corridor?"

Xu Youyou thought for a while, and said: "At 05:30 in the morning, most people are sleeping, and there is no one in the corridor. When I ran downstairs, I saw a few dormitories on the 7th floor open, and someone came out to check the situation. On the 8th floor, It seems that you are going down?"

Qin Miao said: "Yeah, I was woken up by screams before I went downstairs to watch. Didn't anyone come down from the 8th floor?"

Xu Youyou nodded seriously: "Probably not. But I went downstairs from the stairs on the west side, I don't know the east side."

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, she was not very friendly. She just said coldly, "I'm sleeping in the dormitory, so I don't know what happened this morning. I don't know Xie Xiangqin and Zhu Xiaoting well. You can find them." Let others inquire."

After she finished speaking, she directly closed the dormitory door.

Qin Miao felt ashamed, and there was no reason to continue to talk to her.

The girls' dormitory building is a long strip structure with 25 dormitories on each floor. The dormitories are oriented north-south, and there are stairs and elevators on the east and west sides. Girls can choose the stairs and elevators closer to their dormitories to go up and down.

Qin Lu drew a dormitory distribution map on paper and sent it to the group: "A rectangular dormitory building, with elevators and stairs on the east and west sides, dormitories 01-12 on each floor are closer to the stairs and elevators on the west side, and No. 13 Located in the middle, dormitories 14-25 are closer to the east. The deceased Xie Xiangqin lives in 703, which is near the west end, and the suspects Xu Youyou from 811 and Wang Xiaolu from 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 side, so when going downstairs, they will choose the stairs and elevators on the west side out of habit?"

Qin Lu said: "Yes. I visited around. At that time, the people who heard the noise and went to watch were the people in the dormitory next door to 703, and those who were closer to them on the 8th floor. In the dormitory near Dongtou, many people did not hear the screams. , Some people didn’t join in the fun even if they heard it. There were 5 people who came to the scene in the morning, the witness Mao Yue, me, Xu Youyou from 811, and two girls from the dormitory next door to 703.”

Yue Xingwen carefully sorted out the timeline of the murder case in the dormitory——

"At about 5:20, the murderer stabbed Xie Xiangqin in the 703 dormitory. When he found that Zhu Xiaoting had come downstairs, he called Zhu Xiaoting on Xie Xiangqin's cell phone. Through the illusion of words."

"At 5:21, the murderer sent Zhu Xiaoting a Wechat message saying 'we should have a breakup', and left a Wechat record on Zhu Xiaoting's mobile phone, further framing 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 lying in a pool of blood and still breathing. Zhu Xiaoting went to rescue people in panic, and came across the murder weapon."

"At 5:28, Mao Yue returned to the dormitory, saw Zhu Xiaoting holding a knife, and woke up the others by screaming loudly."

"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."

The time was very tight, and if the murderer didn't run in time, he could easily bump into Zhu Xiaoting who was going upstairs.

The entire corridor of the female dormitory is about 50 meters long. Since the 703 dormitory is located at the west end, it is only 6 meters away from the west stairs and 44 meters away from the east stairs. She ran halfway, once Zhu Xiaoting's elevator reached the 7th floor, as soon as she opened the door, she would see her running away in a hurry.

This is why Zhu Xiaoting heard footsteps in the stairwell after taking the elevator to the 7th floor——

At that time, the murderer had just escaped from the stairs on the west side.

There are two possibilities for her to run upstairs. One is that her dormitory is upstairs, and it will be safe to run back to the dormitory; building.

If the murderer is a female medical student who lives on the 8th floor, he can fully meet the conditions for committing the crime.

Xu Youyou's gossip everywhere doesn't look like a murderer, but it doesn't rule out that she has top-notch acting skills and deliberately spread rumors about Zhu Xiaoting's murder; Wang Xiaolu was indifferent, only saying that she was sleeping in the dormitory and didn't know what happened.

Since the monitoring system in the corridor of the girls' dormitory happened to be broken in the past few days, the suspicion of both of them cannot be ruled out.

It depends on who has the key to 703.

At this time, Jiang Pingce, Ke Shaobin and Xin Yan had just left the school and were investigating the surrounding areas.

They found a supermarket in front of the school, bought a pack of tissues, and asked the cashier at the front desk: "Where is there a place to get a key around? I lost my dormitory key, and I went to 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 forward and turn right for ten meters. There is a hardware store that can provide keys."

Jiang Pingce asked, "Is this the only store?"

The girl nodded: "This is the one near the school!"

Ke Shaobin thanked him, and the three of them walked around the corner side by side. Sure enough, they saw a hardware store. A middle-aged man was busy in the store. A student was looking for him to buy nails, saying that the air-conditioning line in the dormitory had fallen off and needed to be nailed again. one time.

The boss smiled and seemed to have a good temper. After the two students left, the three of Jiang Pingce took a step forward.

Xin Yan asked, "Boss, can you provide a key here?"

Boss: "Yes, what kind of key do you want?"

Xin Yan took out a key from his pocket: "It's the kind of key in the school dormitory. My roommate accidentally lost the key, so I'll give him one." As he spoke, he looked at Ke Shaobin.

Ke Shaobin immediately cooperated with him in acting: "Oh, maybe it was dropped in the gymnasium while changing clothes yesterday. Boss, how much does it cost to get a key?"

The boss took a look at the key and said, "This kind? 10 yuan."

Jiang Pingce suddenly asked in a low voice: "If I use plasticine to take the mold of the key, can you make it here?"

Ke Shaobin looked at Jiang Pingce in surprise.

The latter looked cold 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 matching is made by taking the mold. Why, you also lost the key?"

Jiang Pingce said lightly: "It's not me, it's my friend who lost the key to the laboratory a few days ago. I'm afraid the teacher will scold him, so I plan to take the spare key to get a mold for the next experiment and come to you to make one. Give it back to the teacher."

The boss said: "No problem, you can bring the mold! There are students who have done this before. If there is a mold, I can make it for you in 10 minutes."

Xin Yan and Ke Shaobin: "..."

The ability of Xueba's cliché is really awesome. Ke Shaobin excitedly pulled out a photo from his mobile phone and asked, "Boss, is this the classmate who took the mold to match the key?"

The boss shook his head: "No."

Ke Shaobin continued to turn back: "Where's this one?"

The boss continued to shake his head: "No. Alas, you students always lose their keys. There are so many people who come to me to get keys, how can I remember them all!"

Just when Ke Shaobin turned to the fifth photo, the boss's eyes suddenly lit up: "It seems to be this classmate! He wears glasses and is gentle. That's right, it's him!"

Ke Shaobin confirmed, "Chen Kaiming from the School of Chemistry?"

The boss laughed: "I don't know his name, 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 girls."

Ke Shaobin quickly found 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 called up the dead Xie Xiangqin's photo from his phone.

"Huh? This girl seems to have been here before! She came with her boyfriend. I remember very clearly that she complained that her boyfriend accidentally lost her key..." The boss scratched his head, "By the way, you ask What are these for?"

"It's nothing, these are my classmates. They are the ones who introduced you to come here to distribute the keys." Jiang Pingce calmly put away the phone.

"Get one for us, and get it later." Xin Yan left a key and 10 yuan, and the three turned and left.

After returning to the dormitory, Jiang Pingce asked in a low voice: "Ke Shaobin, did you record it?"

Ke Shaobin took out Xiaotu from his pocket and said, "Xiaotu has been recording!"

After Xiaotu is upgraded, it can record audio and video, and monitor designated areas within a certain period of time. Its body grows up to Ke Shaobin's waist, but it can also shrink back to the original palm size for easy portability, turning 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 Xiaotu's recording to his laptop, and then to the WeChat group.

After listening to the recording, Yue Xingwen couldn't help sending a thumbs up: "The information obtained by Ping Ce is very critical. 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 The laboratory got potassium cyanide. In addition, Xie Xiangqin also lost the key, and went to match it with her boyfriend."

Lan Yarong analyzed: "So, the murderer who killed Xie Xiangqin didn't get a key to the 703 dormitory, but took away the key that Xie Xiangqin lost?"

Xie Xiangqin lost the key, this clue is very important!

Lin Manluo followed this train of thought: "The boss said that her boyfriend lost the key. Could it be that the murderer has something to do with her boyfriend, or her boyfriend is also suspected?!"

Yue Xingwen suddenly said: "Do you think that the murderer who killed Xie Xiangqin must be a girl?"

Someone died in the girls' dormitory. Everyone's first reaction was that the girls did it. After all, boys can't get in.But……

Ke Shaobin's brain flashed: "Is there a problem with the access control of the girls' dormitory in Building 6? People like Zhu Xiaoting and Mao Yue can return to the dormitory at 5 o'clock 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 just broke down in the past two days and are being repaired."
