It's a pity that after they found Mo Li, who had just graduated from college and was doing an internship at an e-commerce company, they found that their best friend may not be the one who knows you best.

Mo Li and Wei Zishan are indeed very good, and she herself thinks that she is Zishan's best friend.

"It's really scary for that to happen, if it weren't for ...... We said we would go to college together and work for the same company. Mo Li didn't expect them to come to her to ask her about the case four years ago, "Hasn't the prisoner been caught yet?"

"We are pursuing this case and there are new leads this year. ”

"Do you remember the games that Wei Zishan liked to play at that time, do you have any special friends?"

Mo Li shook his head: "Although we are often together, I am a resident student, she is a day student, she usually plays some games, she told me one or two, but I have never played so I can't remember." It should be the games that were more popular in those two years......"

After chatting for a while, when the two said goodbye to the girl, the girl also specially instructed them, hoping that they could catch the murderer as soon as possible and let their friends go with peace of mind.

"It's a failure!" Luo Yin was disappointed.

"Expected. "Ying Mingyu mends the knife.

"You kid already guessed it?"

Ying Mingyu did not deny it: "Didn't the teacher say it, this Mo Li is a good girl." Wei Zishan is the opposite, naughty and clever. This complementary type of friends, although they can make friends, probably don't have many common hobbies. ”

"So what's next?"

"While it's still early, go and meet the Hanghang you said, the ordinary friends who are crazy to play together, and you may accidentally grasp some clues. ”

Shi Hanghang studied in a junior college, graduated last year, and has been working as a phone bill in the mobile phone business hall for several months.

When they found her, the girl was playing a game on her phone, and when she saw that they didn't even look up, she asked, "How much?"

"Something to ask you. Luo Yin knocked on the workbench and showed his ID to enter the process, but he didn't get a response.

"What's the matter, say. Shi Hanghang did not lift her noble head.

Luo Yin glanced at Ying Mingyu, and the eldest young master took the words and asked directly, and did not insist on identifying himself.

"What games did Wei Zishan like to play four years ago, and did she have any special friends?"

Hearing this question, Shi Hanghang finally put down his mobile phone and raised his head, and after seeing the person clearly, he was stunned for half a second, and then couldn't help but let out a "wow".

"Handsome guy, you look like a character in the game I've been playing recently. ”

Luo Yin turned his head and tried to hold back his laughter, but failed. The current little girl is really too difficult to control, and even the police uncle dares to tease.

Ying Mingyu ignored his teammates who couldn't help him, and showed his ID at this time.

"Zishan...... I told my police uncle before that we were playing XX World, and everyone was playing at that time. Speaking of more special friends, it's a boy I met in an Internet café, it seems to be that kind of gangster, I don't know what his full name is, anyway, Zishan called her Brother Qiang, and I called it that. ”

"You're talking about Chen Tianqiang, why do you think he's special?"

Shi Hanghang flipped the black screen of the mobile phone with one hand: "I don't know if he is interesting to Zishan, once he sat near us, and then they fought together, and then they bought us water and supper or something...... Maybe he's that kind of person. Later, I made an appointment to play games together, but I didn't hear Zishan complain about him, and probably didn't do anything strange, right?"

"I said this four years ago, didn't you look it up?"

"What about other netizens, such as those who haven't met offline? Has Wei Zishan mentioned any screen names or the like, and it's okay if there are not many times?"

Of course, they checked, and according to the information of the old case, Chen Tianqiang's time proved to be unbreakable. Not only was it impossible for him to be present when Wei Zishan was killed, but it was impossible for him to see the deceased even three days before and after. Because of the crowd fighting, just three days before the estimated time of death, Chen Tianqiang was arrested and squatted for seven days before coming out.

An irrebuttable alibi.

Shi Hanghang thought for a while: "I don't remember, didn't you all check it at the time?

"Thank you for your cooperation. ”

After going out, Luo Yin complained: "There is no progress." ”

Except for the impossible Chen Tianqiang, Shi Hanghang did not provide more help.

Ying Mingyu pondered and said: "The friend list may be useful, can the technical department still find out the people at that time?"

"You computer novice, if you didn't check it at the time, how can you check it now? This game has long been outdated. Luo Yin continued to popularize science, "It is estimated that this game development company has already deleted the records of four years ago, and the account will be deleted if it is not played for too long." ”

"......" Ying Mingyu remained silent, he had no idea.

"I remember, there is a list of saved friends in the physical evidence, which can be considered a clue. Luo Yin patted Ying Mingyu's shoulder to comfort him.

Ying Mingyu didn't appreciate it, and he didn't say a word and was ready to go back to the bureau.

It's almost time to go back and sort out everyone's investigation today, maybe the other two deceased people have the same or similar hobbies, and they will soon find a grip.

Bao Zhan and Ding Yuan spent a lot of time reassuring her parents the day before, and after asking Liu Sisi's house about it, they asked them not to touch the things everywhere first, and there would be a trace inspection to check it later.

Because it was only mid-August and the school had not yet opened, they spent a lot of time communicating with the school, found the main teachers of Liu Sisi's major, and contacted them one by one to confirm their whereabouts.

Until last night's meeting, they only saw the teachers of the two main courses, both of whom were female teachers, who expressed their grief over what happened to Liu Sisi and did not provide them with much information.

After dawn today, they continued to visit the teachers who stayed in the local area, and at the same time tried to contact local friends who were in the same major as Liu Sisi.

In the afternoon, after they met a girl named Tan Lin, they made a little discovery.

"Sisi and I are classmates in high school, we applied for this school together, and we chose the same major, but I didn't expect it to be ......" Tan Lin cried as she spoke, wiped her tears and continued, "Sisi has a wide range of knowledge, she likes to read very much, we all love to joke, saying that she is 'Bai Xiaosheng'." ”

"Sisi likes martial arts very much, so I quite like us to call her that. I wanted to choose an English major at the time, and I thought she wouldn't be willing, but I didn't expect her to say yes without saying a word, and told me that she would write martial arts novels in English in the future, so that foreigners could also take a look at our Chinese culture. ”

Bao Zhan and Ding Yuan are very sorry, it sounds like the deceased this time is a learned and ambitious girl, and it is a pity that she is still young.

"Does Lyuss usually play online games?"

Tan Lin nodded: "You must think that professional girls like us are all nerds, right?"

"How could it be. Bao Zhan felt that the girl's mood had improved, and she pursued the victory.

"When we were in high school, we used to play Audition and Flying Cars together, but when we went to college, we didn't play anymore. Sisi seems to have played some other things, I heard her talk to our physical education teacher before, what is it called... Here we ......."

Tan Lin tried hard to think about it for a long time but didn't come up with it, after all, it was very strange to her, and it was a small thing that she remembered because of this.

"Physical Education Teacher...... I don't know which one, but we'll ask him later. Ding Yuan followed suit, he was suspicious of any of the men in the story.

Tan Lin affirmed them: "Teacher Lu, it's our freshman physical education teacher, and the sophomore year is an elective physical education course, I haven't seen it for a long time." ”

"Teacher Lu?" the two of them planned to find out the specific situation.

The PE teachers were a little marginal, and it didn't even occur to them to investigate the kind of teachers who couldn't attend classes twice a semester at first.

Bao Zhan and Ding Yuan then returned to the school to find out the situation of this teacher Lu, and knew that his surname was Lu Mingmin, and he was currently accompanying his wife and mother to travel to other places and did not return.

Hearing that he has no children and no daughters for the time being, the two also specially inquired whether he had any hidden diseases, but the contact person of the academic affairs office said that he had not heard of it.

They immediately reported the news to the people who were checking the information at the hospital, and asked them to pay special attention to the name Xia Lu Min.

It was late these days, so they hurriedly ate something to fill their stomachs, and rushed back to the bureau for a meeting.

"Are you reliable for our suspicions?"

Ding Yuan was silent for a while: "I won't know until I check it." ”

"If we are really lucky enough to fight crookedly, this time we can solve the case before the boss!" Bao Zhan patted his thigh, as if this matter was a foregone conclusion.

Hearing him say this, Ding Yuan couldn't help but hook the corners of his lips, but he held back.

Fang Jinshi and Da Zhuang drove to Meishi City overnight in the evening, and the time happened to be early the next morning, and after discussing the case with the local police, they went to the home of the deceased Ye Xiaojia to understand the situation.

This girl is really too homely, her family can say very few things, and her friends are surprisingly few, but they all say that she is a gentle and good-tempered chronic child, who has never had a grudge against anyone, and has no special hobbies.

"She just plays with the computer and mobile phone all day long, and she doesn't play any games, probably just to play this type of casual game. Even Ye Xiaojia's neighbor didn't say anything more.

"Playing and Lianlian, can you still play against people online?" Da Zhuang was really unfamiliar with this kind of thing, and discussed it with Fang Jinshi after coming out.

"Yes, you can, but it's probably hard to get asociative. ”

They have already taken back the computers and mobile phones that were returned to the Ye family's parents, and the trace inspection will re-investigate the use records, but Fang Jinshi estimates that it is unlikely that they will find it.

The situation on their side was simple, but it was not too late to end, and after returning to the bureau, they contacted the provincial capital and prepared for a video conference.

Fang Jinshi had a gut feeling that this Ye Xiaojia might become a nail to interrupt the clues of the serial case like Chu Jun, the third deceased in the last Jin Yang case.

Sometimes, the simpler the deceased, the fewer social ties, the more detrimental it is to the case. In particular, this kind of serial murder case has greatly increased the obstacles.
