Escape From the Library

【Innocence Defense-09】

Most male and female dormitory buildings in schools have access control systems. Students who come home late need to register the reason at the dormitory office, and the dormitory auntie will open the door for you.If a boy wants to enter a female dormitory, he must write clearly which dormitory he will go to and how long he will stay there, so as to ensure the safety of the student dormitory.

However, Beishan University is different this time.Since the dormitory access control system and monitoring system happened to be broken in the past few days, since people like Mao Yue and Zhu Xiaoting were able to return to the dormitory after 5 o'clock in the morning, and they were not stopped by the dormitory auntie, it is possible for the boys to sneak into the girls early in the morning dormitory!

The murderer who killed Xie Xiangqin in the 703 dormitory, in addition to the people who had enemies with her in the girls' dormitory, may also be a boy!

Yue Xingwen hurriedly said, "Qin Miao, please ask the dormitory auntie, did you see any strange people entering the girls' dormitory around 5 o'clock this morning?"

Qin Miao replied: "When the police came to the scene this morning, they asked about it. The dormitory aunt was sleeping at the time. Let alone seeing other people, she didn't even see Zhu Xiaoting and Mao Yue."

Yue Xingwen frowned, and continued to ask: "When you went to investigate Zou Yijia, did you have any doubts?"

Ke Shaobin said: "Zou Yijia is only about 175cm tall, but he is quite handsome. He is the kind of sunny handsome guy. He also has a cheerful personality and is willing to help others. He likes to play games. Last night, he played with his roommate until the early morning At 4 o'clock, several people fell asleep when they were too sleepy, and slept until 11 o'clock in the afternoon."

Yue Xingwen: "That is to say, the four people in their dormitory went to bed at 4 am and woke up at 11 am. Due to staying up late, everyone slept very hard. They are not sure if any roommates have gone out. ,Right?"

Ke Shaobin was taken aback for a moment, and finally noticed the loophole.

All four said "we slept until noon", but in fact, the other three didn't know whether any roommates had gone out during the sleep.

A person who is asleep cannot give other people an alibi!

Jiang Pingce said: "Zou Yijia lives in Building 5, 105. It is very convenient for people in this dormitory to go to Building 6. After going out, go around the woods. It only takes a dozen meters to reach the west door of Building 6."

On the 1st floor, it is really convenient to go out.

Yue Xingwen asked: "What about the surveillance in the boys' dormitory?"

Ke Shaobin said helplessly: "The monitor at the entrance of Building 5 is also broken. The monitors bought by this broken school must be of poor quality. A batch of them broke recently and are being repaired. It happened during the maintenance period. The murderer must not be impulsive. Premeditated?"

Yue Xingwen carefully sorted out the current doubts, and posted his thoughts in the group——

"First, Xu Youyou and Wang Xiaolu, two medical school girls, live in 8 and 811 respectively on the 812th floor. They were in the dormitory last night, so it was convenient for them to go downstairs to commit murder. They understand the structure of the human body and can kill them with one knife. The suspicion cannot be ruled out;

Second, among the girls in dormitory 703, why did Mao Yue come back early in the morning and saw Zhu Xiaoting holding a knife?Could it be that after Mao Yue killed Xie Xiangqin, he planted his roommate, and then deliberately returned to scream?This possibility should also be considered.

Third, there is another roommate in dormitory 703, Li Huijuan from the School of Life Sciences, who has not been seen until now. I don’t know where he went last night. Maybe this person still has clues to be discovered;

Fourth, if it is a boy who kills, the dormitory where the deceased's boyfriend Zou Yijia lives is very suspicious.First of all, Zou Yijia lost the key to the 703 dormitory. This key is very important.It is possible that Zou Yijia hid the key under the pretext of "lost" and killed his girlfriend because of emotional conflicts; or it may be that his roommate stole the key and killed Xie Xiangqin because of love and hatred. "

After a whole day of investigation and sorting out, the idea of ​​the case gradually became clear.

Liu Zhaoqing joked in the group: "The four points listed by Xingwen are all the key points of the exam, so I need to take notes!"

Everyone typed one after another: "I've already taken a screenshot, so I'm going to memorize it now." "It feels so good to take the exam with Xueba. I think we can score more than 90 points in the exam again this time!"

Yue Xingwen sent a smiling face, and then said: "Senior brother Liu, you can check the situation of Xu Youyou and Wang Xiaolu at the hospital. Medical students in their senior year will practice in the hospital, ask about their daily routine. performance, as well as emotional issues and interpersonal relationships.”

Liu Zhaoqing sent an OK expression: "No problem, I will go to the department where they practiced after work tomorrow."

Lan Yarong said: "Xingwen, let's go to the police force tomorrow to meet Zhu Xiaoting. Since she has been secretly in love with Zou Yijia for several years, she must be very clear about Zou Yijia's situation. Besides, she and Liu Jiajia are best friends, so there should be clues. Dig deep."

Zhu Xiaoting is introverted, and Zou Yijia is her junior brother. She likes him, but she has never dared to say it out loud.But she must have known the other party's interests and hobbies, and maybe she also knew the situation of the other party's roommate.

In addition, Li Huijuan, who is Shenyin in dormitory 703, has not appeared so far.

The police may ask her to make a statement, but Xu Yishen's cell division time had already come, and they only had time to listen to the process of the police interrogating Zhu Xiaoting, but they did not hear the police's questioning of other people's information. They still had to find this roommate to continue their investigation.

Jiang Pingce said: "The murder case in the 703 dormitory has a clue now. The beach poisoning case, the suspect has also been locked, right?"

Yue Xingwen nodded and said: "That's right, everyone's progress is still very fast. The key clues from Ping Ce's routine questioning are very important. Chen Kaiming, who is using molds to match keys in the School of Chemistry, needs to be paid attention to."

Qin Lu found out the list of guests who came to the beach barbecue yesterday from her mobile phone, and said, "Chen Kaiming happened to be on the beach yesterday, and he booked a seat in Zone C in advance, for four people."

Zhang Xiaonian popped up and said, "I remember them! They were sitting at table 66 in area C. I delivered food to them at the time, and their relationship should be two couples. Chen Kaiming wears a pair of glasses and looks very gentle. , and served me food, and asked me where the bathroom was. The girl who was with him was small and cute, and offered to help him barbecue."

Two couples?Yue Xingwen said: "Lock these four people, the murderer who killed Liu Jiajia is among them!"

Chen Kaiming from the School of Chemistry assigned a key to the laboratory in private. Either he assigned the key and kept it for himself, or his key was stolen. He and the people around him may get the key to conduct experiments. Potassium cyanide was removed from the chamber.

To be able to get the poison, I happened to be on the beach yesterday, meeting the prerequisites for poisoning Liu Jiajia.

Next, let's see who of these four people has a grudge against Liu Jiajia.

***

Both cases were analyzed clearly, and Yue Xingwen had a good night's sleep.

Early the next morning, he and Lan Yarong set off for the police force, and the two met Zhu Xiaoting again as defense lawyers.

The girl was detained for one night, mentally depressed, and her hair was messed up like a weed.After seeing the two of them, her eyes lit up with obvious joy, and her voice became more energetic: "Lan Lawyer, Yue Lawyer, you are here!"

The girl's trusting and dependent eyes made Lan Yarong's heart soften.Her gaze became softer, and she looked at the girl in front of her and asked, "Xiaoting, do you know Chen Kaiming from the School of Chemistry?"

Zhu Xiaoting froze for a moment, thought carefully for a moment, and then said: "Yes, he is an alumnus of our high school, a science class, and I met him once during the freshman alumni association. This boy is more shy than me, and I haven't said a word to him." .”

Yue Xingwen asked: "High school alumnus, must he know Liu Jiajia?"

Zhu Xiaoting nodded: "Liu Jiajia is our school belle in high school with good grades. There should be no one in high school who doesn't know her. However, Jiajia and I are in the liberal arts class, and Chen Kaiming is in the science class. Our high school is not in the same science class. First floor, Jia Jia probably doesn't know Chen Kaiming, I've never heard Jia Jia mention this person."

A high school alumnus, Chen Kaiming's science class, finally came to Beishan University to study chemistry.Liu Jiajia and Zhu Xiaoting have always been good friends. They are in the liberal arts class. The former entered the law school, and the latter entered the translation school.

Yue Xingwen couldn't help thinking of his high school life.

He is No.1 in the Chinese subject class of No. [-], and Jiang Pingce is the No. [-] in the science class. Although the two did not communicate much in high school, they have always paid attention to each other.

So, is it possible that although Liu Jiajia from the liberal arts class doesn't know Chen Kaiming from the science class, Chen Kaiming has been paying attention to this school belle? !After all, Liu Jiajia is pretty and has good grades. There must have been many boys who had a crush on her in high school.Boys in adolescence are just beginning to fall in love, and it is estimated that many people regard her as a goddess.

The day she drowned in the sea, she was wearing a bright red dress. At dusk, she took a lot of photos with a few girls on the beach. At that time, Chen Kaiming was having a barbecue on the beach in Area C. He must have seen Liu Jiajia taking pictures at the beach with someone. screen.

——If you can’t get her, just destroy her?

This motive for committing the crime is also established.Some people are psychologically distorted, and there are many murderers who love to kill in the depths.

Yue Xingwen took a deep breath and asked, "You and Liu Jiajia are best friends who talk about everything, right? Did she tell you who her suitors are? Or, what is her view on love?" like?"

Zhu Xiaoting said: "Gajia has many suitors. People often send her love letters, but she will reject them very well. Her dream is to be an excellent lawyer. She spends all her time studying and doesn't want to fall in love with others. After she plans to work, she will find a man who is mature, stable and has a common language."

Judging from Zhu Xiaoting's description, this Liu Jiajia is a beautiful, intelligent and sensible girl. She has never been complacent because of her good looks, and she has never played with boys' feelings. She politely rejects those who chase her. .

Even if a normal boy is rejected, it is impossible for such a girl to kill her.

But there are always some psychopaths among human beings!

Yue Xingwen looked at Lan Yarong, and the two exchanged a look.Lan Yarong took out a photo from her mobile phone and asked: "Chen Kaiming and his girlfriend Lin Xuefei were at the beach yesterday, have you seen them?" Zhu Xiaoting was stunned for a moment, then suddenly said: "Ah, this girl……"

Yue Xingwen looked serious: "What's wrong?"

Zhu Xiaoting said: "I remembered. When Jiajia and I were taking pictures at the beach, this girl happened to pass by. I stopped her and asked her to take a few group photos for us. Her photography skills are quite good."

Lan Yarong immediately sat up straight: "And then?"

Zhu Xiaoting thought for a while, and said, "Then she left. She was playing on the beach in Area A. I thought she was from the law school, so I didn't pay attention."

Zhu Xiaoting was not a student of the law school, but participated in this barbecue with her best friend Liu Jiajia. She didn't know most of the law school classmates, so she didn't pay attention to this passer-by girl who "just happened to pass by".

Yue Xingwen then asked, "Have you ever eaten barbecue before?"

Zhu Xiaoting: "Eat it often."

Yue Xingwen: "You will also have diarrhea after eating?"

Zhu Xiaoting froze for a moment, frowned slightly, and said in a low voice, "Diarrhea was not so serious before, and my stomach is okay. Is the food at the seaside not clean because of the sudden diarrhea this time?"

Yue Xingwen said in a low voice: "It's not that the food is not clean, but that someone gave you a laxative—tune the tiger away from the mountain so that you can attack Liu Jiajia."

Zhu Xiaoting: "..."

She had diarrhea all night yesterday, and she couldn't take it anymore early in the morning, so she left the tent and went to school. She planned to go back to the dormitory to rest, and if it didn't work, she would go to the hospital to see a doctor.

Isn't this a coincidence?Not a problem with beach grill food?

Zhu Xiaoting stared blankly at Yue Xingwen, feeling a chill down her spine: "Yes, someone added something to the barbecue I ate, deliberately causing me diarrhea?"

Yue Xingwen nodded: "Yes. The murderer may have no grudge against you, and he didn't intend to plant you on purpose. He just wanted you to leave Liu Jiajia. In this way, Liu Jiajia will be alone, and the murderer will be able to kill you with poison. Her. As for the bottle with only your fingerprints on it, it's because the murderer wore gloves when poisoning."

Disposable plastic gloves are everywhere in barbecue joints.

The murderer didn't deliberately frame Zhu Xiaoting, but put on disposable gloves and poisoned Liu Jiajia's bottle.However, the bottle happened to be given to Liu Jiajia by Zhu Xiaoting, so Zhu Xiaoting's fingerprints were left on it.

This is consistent with Yue Xingwen's initial guess——

The murderer of the beach case didn't have any deep hatred with Zhu Xiaoting, nor did he deliberately frame her. He didn't even know Zhu Xiaoting, but he just took advantage of Zhu Xiaoting's departure.

The murderer of the dormitory case called and sent WeChat again, that is malicious framing!
