[Not Guilty Defense-09]
Most school male and female dormitories have access control systems. Students need to register the reasons at the dormitory office when they return late, and the dormitory aunt will open the door for you. Boys who want to enter the girls' dormitory should also write clearly in which dormitory they are looking for and how long they will stay, so as to ensure the safety of the student dormitory.
However, this time Beishan University is different. Since the access control system and monitoring system of the dormitory have just broken down these days, since Mao Yue and Zhu Xiaoting can return to the dormitory at 5 o'clock in the morning and are not blocked by the dormitory aunt, then it is possible for boys to sneak into girls early in the morning. dormitory!
The murderer who killed Xie Xiangqin in the 703 dormitory, in addition to the people who hated her in the girls' dormitory, may also be a boy!
Yue Xingwen hurriedly said, "Qin Miao, please ask the dormitory aunt, did you see any strange people entering the girls' dormitory around 5 o'clock this morning?"
Qin Miao replied: "The police asked when they came to the scene this morning. The dormitory aunt was sleeping, not to mention seeing other people. She didn't even see Zhu Xiaoting and Mao Yue."
Yue Xingwen frowned and continued to ask, "Did you have any doubts when you went to investigate Zou Yijia?"
Ke Shaobin said: "Zou Yijia is only about 175cm tall, but he is quite handsome. He is the kind of sunny guy with a cheerful personality and is willing to help others. He likes to play games, and he played black games with his roommates until the early morning last night. At 4 o'clock, a few people fell asleep when they were too sleepy, and slept until 11 noon."
Yue Xingwen: "In other words, the four people in their dormitory went to bed at 4 am and woke up at 11 noon. Because of staying up late, everyone slept to death, and they were not sure if any roommates had gone out. ,Right?"
Ke Shaobin was stunned for a moment, and finally noticed the loophole.
All four of them said "We slept until noon", but in fact, the other three did not know whether any roommates had gone out during the sleep.
A person who is asleep cannot be an alibi for others!
Jiang Pingce said: "Zou Yijia lives in Building 5, Room 105. It is very convenient for people in this dormitory to go to Building 6. After going out, go around the woods, and you can reach the door on the west side of Building 6 in just a dozen meters."
On the 1st floor, it is really convenient to go out.
Yue Xingwen asked, "What about the monitoring in the boys' dormitory?"
Ke Shaobin said helplessly: "The monitor at the entrance of Building 5 is also broken. The monitor bought from this school must be of poor quality. A batch of monitors have been broken recently and are being repaired. The accident happened during the repair. 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 811 and 812 on the 8th floor, respectively. They were in the dormitory last night, so it was convenient for them to go downstairs.
Second, among the girls in the 703 dormitory, why did Mao Yue come back early in the morning, just to see the scene of Zhu Xiaoting holding a knife? Could it be that after killing Xie Xiangqin, Mao Yue framed his roommate, and then came back to scream on purpose? This possibility should also be considered.
Third, there is another roommate in the 703 dormitory, Li Huijuan from the Academy of Biological Sciences, who has not appeared until now. I don't know where he went last night. Maybe this person still has clues that need to be excavated;
Fourth, if it was a boy who killed the murder, the dormitory where the deceased's boyfriend Zou Yijia was located was very suspicious. First of all, Zou Yijia lost the key to the 703 dormitory. This key is very important. It may be that Zou Yijia hid the key under the pretext of 'losing' and killed his girlfriend due to emotional conflicts; it may also be that his roommate stole the key and killed Xie Xiangqin because of love and hatred. "
After a whole day of investigation and sorting, the thinking of the case gradually became clear.
Liu Zhaoqing joked in the group: "The four points listed by Xingwen are the key points of the exam, so you need to take notes!"
Everyone typed: "The screenshots have been taken, so let's go to memorize them." "It feels so good to take the exam with Xueba, I think we can take the exam with more than 90 points this time!"
Yue Xingwen smiled and said, "Senior Brother Liu, check the medical students Xu Youyou and Wang Xiaolu at the hospital. Senior medical students will practice in the hospital, so ask them about their daily life. performance, as well as emotional issues, interpersonal relationships.”
Liu Zhaoqing sent an OK expression: "No problem, I will go to the department where they practiced after going to work tomorrow."
Lan Yarong said: "Xingwen, let's go to the police force tomorrow to see Zhu Xiaoting. Since she has had a crush on Zou Yijia for several years, she must be very clear about Zou Yijia's situation. And 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 each other and has never dared to say it. But she must have known each other's interests and hobbies, and maybe she also knew the situation of each other's roommates.
In addition, Li Huijuan, a classmate of Shenyin in the 703 dormitory, has not appeared so far.
The police may have asked her to make a transcript, but the time for Xu Yishen's cell division had already arrived, and they only had time to listen to the process of the police's trial of Zhu Xiaoting, and failed to hear the information the police asked about other people.
Jiang Pingce said: "The murder case in the 703 dormitory has now got a clue. In the case of poisoning on the beach, the suspect is also locked, right?"
Yue Xingwen nodded and said, "Yes, everyone's progress is still quite fast. The key clues from Pingce's cliché are very important. Chen Kaiming, who took the mold to match the key in the School of Chemistry, needs to focus on."
Qin Lu pulled out the list of guests who came to the beach for barbecue yesterday, and said, "Chen Kaiming happened to be at the beach yesterday. He booked a seat in Area C in advance, and he booked a seat for four."
Zhang Xiaonian came out and said: "I remember them! They were sitting at table 66 in Area C. I delivered them meals at the time, and it seems that their relationship should be two couples. Chen Kaiming wears a pair of glasses and looks very gentle. , He also served me the dishes and asked me where the bathroom was. The girl with him was small and cute, and he took the initiative to help him barbecue."
Two couples? Yue Xingwen said: "Lock these four people, and the murderer who killed Liu Jiajia is among them!"
Chen Kaiming from the School of Chemistry has privately assigned the laboratory key. Either he assigned the key and kept it for himself, or his key was stolen. He and the people around him may have obtained the key for experiments. Potassium cyanide was removed from the chamber.
To be able to get the poison, I happened to be at the beach yesterday, meeting the preconditions for poisoning Liu Jiajia.
Next, we will see who of these four people has a grudge against Liu Jiajia.
***
Both cases were clearly analyzed, and Yue Xingwen slept well that night.
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 overnight, lethargic, and her hair was a mess like a weed. After seeing the two of them, her eyes lit up, with obvious joy in her eyes, and her voice became a little more energetic: "Lawyer Lan, Lawyer Yue, you are here!"
The girl's trusting and reliant eyes softened Lan Yarong's heart. Her eyes softened a lot, and she looked at the girl in front of her and asked, "Xiao Ting, do you know Chen Kaiming from the School of Chemistry?"
Zhu Xiaoting was stunned for a moment, and after thinking carefully for a moment, she said: "I know, he is our high school alumnus, from the science class. I met once in the freshman alumni association. This boy is more introverted than me, and I didn't say a word to him. ."
Yue Xingwen asked, "A high school alumnus, so he must know Liu Jiajia?"
Zhu Xiaoting nodded: "Liu Jiajia is the beauty of our high school, and she has good grades. There should be no high school classmates who don't know her. However, Jiajia and I are in the liberal arts class, Chen Kaiming is in the science class, and our high school Chinese science is not the same. Floor, Gaga should not know Chen Kaiming, I have never heard Gaga mention this person."
A high school alumnus, Chen Kaiming, a science class, finally came to Beishan University to major in chemistry. Liu Jiajia and Zhu Xiaoting have always been good girlfriends. The two are in the liberal arts class. The former went to the law school and the latter went to the translation school.
Yue Xingwen couldn't help thinking of his high school life.
He is the No. 1 in the Chinese class and Jiang Pingce is the No. 1 in the science class. Although the two didn't communicate much in high school, they always paid attention to each other.
So, is it possible that although Liu Jiajia from the liberal arts class does not know Chen Kaiming from the science class, Chen Kaiming has been paying attention to this school beauty? ! After all, Liu Jiajia is beautiful and has good grades. There must have been many boys who had a crush on her in high school. Adolescent boys are beginning to fall in love, and it is estimated that many people regard her as a goddess.
She was wearing a bright red dress on the day she drowned in the sea, and took a lot of photos at the beach with a few girls at dusk. At that time, Chen Kaiming was eating barbecue on the beach in Area C. He must have seen Liu Jiajia taking pictures at the beach with others. screen.
- If you can't get her, just destroy her
This motive is also established. Some people are psychologically distorted, and there are many murderers who love to the depths to kill.
Yue Xingwen took a deep breath and asked, "You and Liu Jiajia are best friends who talk about everything, right? Has she told you who her suitors are? Or, what is her view of love? like?"
Zhu Xiaoting said: "Gaga has many suitors. People often send her love letters, but she refuses them with a good temper. Her dream is to be an excellent lawyer. She plans to find a mature, stable man with a common language after her work."
Judging from Zhu Xiaoting's description, this Liu Jiajia is a beautiful, intelligent and very rational girl. She is not complacent just because she is good-looking, and she has never played with boys' feelings. She has politely rejected her followers. .
Even if a normal boy is rejected, it is impossible to kill such a girl.
But there are always some psychopaths in humans!
Yue Xingwen looked at Lan Yarong, and the two exchanged glances. Lan Yarong took out a photo from her phone and asked, "Chen Kaiming, and his girlfriend Lin Xuefei, they 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 remember, when I was taking pictures with Gaga 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: "Then what?"
Zhu Xiaoting thought about it 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 law school student, 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 care about this passerby girl who happened to pass by.
Yue Xingwen then asked, "Have you ever eaten barbecue before?"
Zhu Xiaoting: "I eat it often."
Yue Xingwen: "Do you have diarrhea after eating?"
Zhu Xiaoting was stunned for a moment, frowned slightly, and whispered, "I haven't had diarrhea so bad before, and my stomach is okay. Is the food at the beach unclean this time with diarrhea?"
Yue Xingwen whispered: "It's not that the food is not clean, but that someone gave you laxatives - Tiaohu Lishan, so that it is convenient to do something to Liu Jiajia."
Zhu Xiaoting: "..."
She stretched her stomach all night yesterday, and she couldn't take it anymore. She left the tent and went to school. She planned to go back to the dormitory to rest. If she couldn't, she would go to the hospital to see a doctor.
Isn't this a coincidence? Not a problem with beach BBQ food
Zhu Xiaoting stared blankly at Yue Xingwen with a chill down her spine: "Yes, someone added something to the barbecue I ate to deliberately cause me to have diarrhea?"
Yue Xingwen nodded: "Yes. The murderer may not have any grudge against you, and he didn't want to frame you on purpose, but just wanted you to leave Liu Jiajia. In this way, Liu Jiajia would be singled out, and the murderer would be convenient for poisoning. She. As for only your fingerprints on the bottle, it's because the killer wore gloves when he was poisoning."
Disposable plastic gloves are littered all over the grill.
The murderer did not deliberately frame Zhu Xiaoting, but put on disposable gloves to poison Liu Jiajia's bottle. However, the bottle happened to be given to Liu Jiajia by Zhu Xiaoting, so Zhu Xiaoting's fingerprints were left.
This is consistent with what Yue Xingwen initially guessed—
The murderer of the beach case did not have a deep hatred with Zhu Xiaoting, nor did he deliberately frame it, and he didn't even know Zhu Xiaoting, but he just took action after Zhu Xiaoting left.
The murderer of the dormitory case called and sent WeChat again, that was maliciously framed!
