Chapter 11, Poppy 11
Luo Siwei discovered this clue after a period of reasoning.
First of all, MYD is a little unfamiliar to ordinary people, but in fact, this word is a computer term, which refers to the database information file created by MySQL. The MYD file stores the actual data in the database.
Taking into account the fact that the suspect was able to leave no trace on the Internet and the police had searched for him many times but failed to identify his true identity, Luo Siwei judged that this person must have a high level of computer skills, so he thought of using this word as the prefix of his email address.
The Computer Science Department of Donglan University is very famous. Luo Siwei copied the student lists of the relevant majors in recent years.
Luo Siwei tried to change these letters into the first letters of the name and input them to check. She found a student named Mo Yingdong in the school roster who seemed to be a match.
But Luo Siwei quickly denied it. The murderer would not leave such obvious clues for others to find him, and the puzzle would not be so simple.
Luo Siwei began searching again, searching for various interpretations online and writing them down to check them out one by one.
Weibo name, no.
Fund account, no.
The speakers, the water dispenser... aren't either.
Luo Siwei kept trying and kept denying herself.
She began to profile the murderer in her mind, who was young, arrogant, narcissistic, perverted and pathological.
He was highly educated and spent a lot of time online. He knew everything about Yu Wanying. In his conversation with Ye Ruxi, every move he made was highly purposeful.
He is good at disguising and hiding.
In addition to their superficial meaning, the three letters MYD must have other meanings.
Why did the murderer choose this as his email address? Everyone has a reason for choosing their email address. Some are nice to hear, some are easy to remember, some have special meanings and can express their own ideas, and some people use their own English names.
She remembered that the person who had stalked and harassed Yu Wanying had made some perverted remarks.
Then she thought of the serial killer who named himself BTK. Bend torture kill, bind, torture, kill.
Combined with the characteristics of the murderer.
After several searches, Luo Siwei locked onto a word: make you die.
Let you die.
Luo Siwei felt that at this moment, she resonated with the murderer, and she might have touched the true meaning of this name.
On the surface, it looked like a normal data storage suffix, but behind it lay a deeply perverted core. Others wouldn't be able to discern the true nature of such an email address, yet it satisfied his perverted mind to the utmost. Just typing those three words would excite him.
Luo Siwei thought again, such a murderer is getting close to Yu Wanying in all aspects, so, will he add her as a friend?
From tracking and inquiring to the final killing, there must be another step in between, which is that he has to get to know her.
He wanted to look at her, talk to her, stand opposite the victim, and have a conversation with her online.
The feeling that he is right next to her but she doesn't know his true identity will fascinate the murderer.
Then, this person should be in Yu Wanying’s WeChat list.
After deducing this information, Luo Siwei made another comparison. Yu Wanying didn't know many opposite-sex people, and even fewer who majored in computer science. She quickly identified a name - Cha Junxi.
Also, will he get close to the people around Yu Wanying?
Luo Siwei recalled the testimony of Xue Rong and Ye Ruxi, who said they had asked their computer science seniors for tips on how to log in without leaving any traces online. They provided several names. Luo Siwei carefully compared the list of names of relevant majors and discovered that there were not only seniors but also a junior fellow student, whose name was Cha Junxi.
Maybe these were just coincidences, and there weren't enough clues for her to completely pinpoint this person.
Luo Siwei searched the police information database and found Cha Junxi's frequently used mobile phone number, and further found the English account of Cha Junxi's other email address.
She discovered that all of Cha Junxi's email addresses began with MYD. It was clear that he really liked this abbreviation.
After checking it over and over again and believing that his inference was correct, Luo Siwei raised his head and announced the result to the two team members.
"I've made some new discoveries. I followed the MYD email address and found someone in the student roster of Donglan University. His usual email address prefix is MYD."
Shen Qing looked up excitedly: "Who is it?"
Luo Siwei said, "His name is Cha Junxi. He's a junior in the School of Computer Science. He's among Yu Wanying's WeChat friends. I suspect he's suspect number four. Further investigation is needed to pinpoint his connection to this case."
Fresh from their snack, the detectives were full of energy and quickly found Cha Junxi's information. The real information about Cha Junxi was also added to the whiteboard.
Among them was an enlarged ID photo. The boy in the photo was a little thin and wore a white shirt. He was only in his early twenties, with slightly long hair that covered his eyes. He had an ordinary appearance and did not look very energetic.
Shen Qing said, "I think this person is highly suspicious. If Yu Wanying finds herself in danger, she will be on high alert and won't be alone. At this time, only someone familiar and close to her can let her guard down. This will give the other party an opportunity to take advantage of her."
Compared to those naturally ugly and burly people, or the junior students she knew from the same school, this identity was deceptive. But in fact, it was more dangerous to be around such a person who was madly infatuated with her.
Soon, they discovered more interactions between Cha Junxi and Yu Wanying.
Ni Xiang reported: "On the afternoon of the day Yu Wanying was murdered, Cha Junxi's class did not have classes."
It can be said that this person is the suspect closest to Yu Wanying. He also had sufficient time to commit the crime and has no alibi.
Shen Qing said: "Then I'll make a phone call and ask him over."
It was nine o'clock in the evening, not yet bedtime for an average college student. Shen Qing called Cha Junxi, then shook his head at Luo Siwei: "Cha Junxi's phone is turned off."
Luo Siwei said: "Call his class teacher."
Shen Qing quickly contacted Cha Junxi's homeroom teacher through the school. The teacher said that Cha Junxi had taken sick leave and was not living on campus recently. After the call, Shen Qing looked at Luo Siwei, waiting for her decision.
Luo Siwei stood up and said, "Let's go to Donglan University now."
The city has fallen into darkness, but the university town of Donglan is brightly lit.
Exam week is approaching, and in order to make it easier for students to review, the school library and study rooms have been open all night.
Cha Junxi's dormitory is a male dormitory. Luo Siwei asked Shen Qing to take a police auxiliary to search first, while she and Ni Xiang went to meet Cha Junxi's class teacher.
The female teacher's surname was Lin. She was short and gentle, and wore a pair of glasses.
Ni Xiang felt that Teacher Lin looked very young and not much older than the students.
Teacher Lin walked over and greeted the two female police officers. While talking to them, he was still desperately calling Cha Junxi's cell phone. He called several times but the phone was always turned off.
When asked about specific matters, Teacher Lin looked embarrassed: "Being a class teacher in college is a bit of a figment of the imagination. I'm only responsible for handling leave requests and contact matters."
The call was always unresolved, and Teacher Lin's expression gradually changed: "That's strange. He usually answers the phone on time. Cha Junxi is quite honest. Could something have happened..."
Luo Siwei asked, "Has Cha Junxi always lived off campus?"
"It started this school year," Teacher Lin explained. "Our school is aligned with international standards, and students can live off campus if they apply. Many students from wealthy families choose to live off campus and reserve a bed in the dorms to get enough rest."
The same situation happened to Yu Wanying before. Although this gives her a higher degree of freedom, it also increases the risk.
Luo Siwei asked Teacher Lin again: "When was the last time you saw Cha Junxi?"
"I saw him yesterday. He said he had a headache recently and asked me for two days off with a doctor's note. Final exams are coming up soon and he doesn't have any classes left, so I approved his leave."
Luo Siwei reminded: "Have you contacted Cha Junxi's parents?"
Teacher Lin said, "I just called his father, but he didn't know much about his situation. He wasn't in a hurry at all and hung up the phone in a hurry."
Ni Xiang looked up and asked, "Have you contacted his mother?"
"I hit her, and her mother had no idea what was going on," Teacher Lin explained. "Cha Junxi's family was divorced, and he lived with his father. Later, it seems his father remarried and started a new family. As for Cha Junxi... once I gave him enough money, I didn't pay much attention to him. So every holiday, he would come to me and ask to stay in the dormitory for a while longer. He even didn't go home for Chinese New Year."
Luo Siwei asked a few more questions, and Teacher Lin answered them one by one. She couldn't help but ask, "You police...are you here looking for him so late at night? Is there something wrong?"
The call she received from the school only informed her to contact Cha Junxi as soon as possible and meet with the police to cooperate with the investigation.
Now being questioned by the police, Teacher Lin felt unsure.
Luo Siwei simply answered her, "Our investigation found that Cha Junxi might be related to Yu Wanying's case. The police are still investigating the specific circumstances."
She said it vaguely, saying that the police first needed to confirm Cha Junxi's suspicion. It was too early to designate him as a suspect.
Teacher Lin showed a hint of surprise on her face. She had heard something about the recent events. "Is that the missing girl?"
Luo Siwei nodded: "So please tell us everything about Cha Junxi."
"He...did he do something stupid..." Teacher Lin sighed. She knew the matter was serious, so she lowered her head and thought carefully before explaining in detail, "Cha Junxi is very smart. His scores could have gotten him into a better school, but he ended up at Donglan because of a failed application. He has good grades in all subjects and completes his homework on time. However, he's a quiet and somewhat unsociable student. He never raises his hand to speak in class, doesn't like participating in group activities, and often misses them."
"Also, he loves playing with his phone. He basically never puts it down during every class. I've reprimanded him several times, and other teachers have also reported similar issues to me. But because his grades are decent, many teachers turn a blind eye."
"Cha Junxi's computer skills are very good, even better than those of his classmates. Some students will ask him for help when they have homework problems or problems they don't know how to solve..."
The information Teacher Lin shared made Luo Siwei even more certain of the suspect's suspicious nature. Just like his email address prefix, which appeared to be an ordinary MYD file name, you wouldn't notice it even if it was mixed in with other computer files. But in reality, it held a hidden threat.
At the end of the conversation, Teacher Lin couldn't remember anything else. She continued, "You can ask Jian Wenlu. He was in the same dormitory as Cha Junxi and was the class monitor."
After talking with Teacher Lin, Luo Siwei contacted Shen Qing.
Shen Qing had just finished briefly questioning a few of his roommates and was searching the dormitory.
Luo Siwei said, "Have the students put on their clothes. I'll take Ni Xiang up to take a look."
Cha Junxi's dormitory was on the third floor of the men's dormitory. Luo Siwei took Ni Xiang all the way up. They walked quickly in the corridor. The corridor of the men's dormitory had a special smell. Even during the stressful exam week, the sound of people playing games could be heard coming from the dormitory.
A shirtless boy came out of the dormitory, humming a song. When he saw Luo Siwei and Ni Xiang, he ran back and slammed the door shut. Some other boys peeked in to see what was going on.
Luo Siwei took Ni Xiang and walked through the corridor without looking around, all the way to Cha Junxi's dormitory.
The dormitory door was open. Shen Qing and the auxiliary police officer were looking through the books on the bedside bookshelf one by one. In order to avoid making a mess, they took down a book, flipped through it, and then put it back.
The other three boys in the dormitory were all there. They sat in their chairs, not daring to breathe.
Luo Siwei asked: "Did you find anything?"
Shen Qing said: "They are all normal student supplies. They are cleaned very cleanly. The wardrobe is basically empty. There is nothing special found so far."
Luo Siwei wasn't surprised by this result. Even if Cha Junxi was a suspect, he was still a student, and it was unlikely he would leave any obvious traces in a dorm he didn't live in. However, this was where he had lived for a long time, so if he was acting strangely, he would definitely leave some clues here.
Thinking of this, Luo Siwei walked closer. She touched the items on the table with gloves, and then looked at Cha Junxi's desk carefully.
A thick table mat, some cute mugs, and aromatherapy on the corner of the table...
Luo Siwei found something strange. The desk didn't look like a boy's, but more like a girl's.
Then she suddenly remembered something, and Luo Siwei frowned: "There is something wrong with this arrangement."
Shen Qingzhi stood up and asked, "Where?"
Luo Siwei took out her cell phone and showed them Yu Wanying's Weibo. Some of the photos showed the layout of her dormitory in the corners.
Ni Xiang looked down and discovered the abnormality that Luo Siwei pointed out: "There is something on the table that looks the same!"
"Not only that." Luo Siwei looked up at the bookshelf, "The books are arranged exactly the same..."
Shen Qing looked at the photo and indeed found a clue. The books on Cha Junxi's bookshelf and the books on Yu Wanying's bookshelf were exactly the same in terms of their arrangement.
The books on the bookshelf in front of me are very diverse, including novels, reference books, and some related professional books and reference materials.
Cha Junxi is a computer science student and has no use for these books.
Ni Xiang continued comparing the photos. "These... the table mats, the water cups, the stationery... are all placed in the same place. There's even a piece of clothing hanging by the bed. Is he copying Yu Wanying's dorm layout?"
"You haven't observed it carefully enough." Luo Siwei pointed out a few details to them. "The cup and the clothes are different styles. He bought a men's version. To be more precise, it's Yu Wanying's couple's version."
Ni Xiang's eyes widened in disbelief. She carefully checked the details and found they all matched. She felt sick and cursed, "Pervert..."
