After the two sides got on the phone at the designated time, everyone briefly discussed the situation of today's investigation. Not surprisingly, the only person who could start the investigation was Liu Sisi's physical education teacher.

After searching old case files and gathering information from people who answered calls from police stations in various places, the bureau has found no new suspicious cases that can be merged into the case.

After a day of research and comparison, the forensic doctor confirmed that the sleeping pills left in the bodies of the three deceased cases had the same ingredients. Unfortunately, they were very common prescription drugs and had no investigative value.

The trace inspection side is looking for reference value parts from a large number of on-site photos, but has not yet found any clues that can explain what the vehicle is. Wang Tao agrees with Li Lianbing's view that there is a conflict between the vehicle and the murder weapon.

They suspected that the deceased had a car, but the murder weapon turned out to be a very low-quality and not high-end thing.

Regardless of whether it is a headband bracelet or a woven belt bag, judging from the scars on the deceased's wounds, there are rough edges and uneven edges, and it is by no means an exquisite and high-quality product.

Why do you carry such a crude thing with you even though you have a car? What could be the murder weapon?

They have been struggling for a day.

"Jin Shi, will you come back tomorrow?" There was no one else around, and after finishing the business conversation, Fan Hua asked about something unrelated.

Fang Jinshi glanced at the silent captain, and after thinking about it, he answered: "I will stay here for another day or two to see if there are any other clues on your side that we need to cooperate with the investigation. In addition, I want to wait and see what happens here.

Technical analysis of the deceased's computer and mobile phone may lead to new discoveries."

Ying Mingyu agreed to her decision without saying anything and didn't pay attention to his friend's eyes.

Although there was not much progress in the case that day, the call between the two parties lasted for three hours, and it was late at night when it ended.

The trace examiner and forensic doctor were exhausted and declared dead, so they went back to rest after the meeting. The criminal investigation team began to rotate their duties. Ying Mingyu naturally wanted to stay on the first shift. He was used to it, but this time Bao Zhan volunteered to take the lead.

, let him take a break first and come to hear their good news the next day.

Although he was puzzled, Ying Mingyu didn't refuse. Seeing that it was not early, he thought for a moment and didn't call Qianqian. He went home and took a shower and lay down to sleep.

Ding Yuan probably knows what his partner is thinking. This kind of serial case often depends on luck, especially if you want to solve the case quickly, and he and Bao Zhan seem to have a little luck today. Bao Zhan definitely doesn't want to let this opportunity go.

, want to grab the top spot.

Bao Zhan went to the technical side to follow up on the investigation, and also provided Lu Min's home address. He hoped that they would investigate and verify his home's network address to see if there were any overlaps among the contacts of the deceased.

.

Ding Principle went to accompany Liu Minmin, who was working overtime after taking a break, to look for old case information. Seeing that she was looking seriously, he made a casual conversation.

"Master said he thinks there must be related cases, and I believe him."

After encountering the bad news, Ding Yuan didn't say anything more and started working in silence.

After a busy night, there was nothing new on their side, but there was something new at Bao Zhan's end.

Technology found an account that often took her to play games from the undeleted game records on Wei Zishan's computer, and traced the last login address, which happened to be Lu Min's home address.

This is definitely not a coincidence. This Lu Min is now related to the two deceased people.

As soon as Ying Mingyu arrived the next morning, Bao Zhan took his last breath and proudly reported the matter, while Ding Yuan persisted and listened to the end.

"I know, you have worked hard, go back and rest, we will check next."

Luo Yin laughed softly at the side: "Xiao Yingzi, you can still speak a few words of human language. Is it true that they followed you in vain?"

"Our boss is less verbal and more soft-spoken." Bao Zhan said the last sentence and withdrew with Ding Yuan.

After they left, Luo Yin complained: "Why didn't I see you treat me to a nice meal yesterday?"

"Go check it out as soon as you have time." Ying Mingyu was about to leave when Meili called him while talking.

After hearing from Meili that Liu Minmin was still checking files and refused to go back to rest, he had no choice but to persuade her and told her to go home and rest and come back later.

"Master, I'm fine. I'll just go upstairs and take a nap later."

"Go back to sleep first. Come tonight... discuss it with us and let you go to the front line tomorrow."

"Really Master?!" Liu Minmin raised her face, her face pale with dark circles under her eyes.

Ying Mingyu nodded: "Go back quickly."

Liu Minmin happily put down her work and prepared to go home. She stumbled when she stood up. Ying Mingyu stretched out his hand but did not help her.

After sending the people away, when Ying Mingyu went back to find Luo Yin, he was chatting with Chen Chen who had come to help them solve the case diligently.

"Have you got your 'little lover'?" Chen Chen boldly provoked Ying Mingyu.

"Are you leaving?"

"Come on." Luo Yin smiled and followed Ying Mingyu who ignored Chen Chen.

They went directly to the school's Academic Affairs Office, where the director, who was urged to work overtime from home, received them.

"We would like to know where Teacher Lu Min's ancestral home is? Does his family have anything to do with Meishi City?"

After all, the director had been an old man for many years, so he gave them accurate information after some thought.

"This is about Meishi City. Lu Min's wife seems to be from there. Sometimes during the holidays, I heard that he would take his wife back to visit."

"Do you have the address of his wife's natal home here?"

The director shook his head: "His wife is not from our school and we haven't talked to her before. I don't know. What's wrong with him?"

"It's okay, I just want to find out something from him."

"Okay, I heard them say that they contacted Lu Min yesterday and he should be back in the next two days."

"Thank you for cooperating with our work." Luo Yin was responsible for the polite words.

"It should."

They immediately informed Fang Jinshi of the situation and asked them to come to investigate.

"Xiao Yingzi, do you really think there is something wrong with that physical education teacher?" On the way back to the bureau to see the autopsy and trace examination, Luo Yin said a few words, "The physical education teacher should be in good health. Maybe he doesn't have children.

It’s just that I’m still young and don’t want it.”

Ying Mingyu pondered for a moment: "Let's wait for the news from Sister Fang."

Although Luo Min seemed to be related to the deceased Ye Xiaojia because his wife was from Meishi City, the actual situation is still unknown.

Especially from the video conference last night, it sounds like Ye Xiaojia is a homebody and it is difficult to find common ground with others.

"Xiao Yingzi, you are really cautious. Let's just talk about the case casually. We don't need to be so cautious, right?"

Ying Mingyu sighed lightly: "I also hope we are so lucky, but I'm afraid it won't be that simple."

"No matter what, we will definitely be able to catch that guy's little tail."

"We have to hurry up." Ying Mingyu was worried that the murderer's pace would speed up. There were still about ten days until the end of the summer vacation, and he didn't want to be together again.

The autopsy has been re-examined, and the forensic doctor also wants to restore the instrument that caused the lower body injury. The difficulty is too high, and the disposal is still in the exploratory stage. Moreover, this task is a bit embarrassing for Du Xiuxiu. She should be the one who can provide reference opinions.

In fact she has no experience.

Ying Mingyu felt that this was purely Fan Hua's academic control: "Wait until you have time to study it. This murder weapon has little reference value. Let's focus on finding what the deadly weapon could be first."

Not to mention that investigation can only be carried out unless the instrument used by the murderer is particularly special. The use of instruments only started in this case, and it is difficult to verify and screen independent evidence.

There are countless clues in the trace inspection. The photos and corresponding physical evidence from the two previous cases have been collected and compared together, which is dazzling.

Ying Mingyu and Luo Yin spent time in the same place, hoping to find some clues from the numerous photos.

Fang Jinshi and Da Zhuang went through the local police station and quickly found the home address of Lu Min's wife Yao Yuan, and went to inquire about the situation.

They took the aunt from the local neighborhood committee with them to learn about his family's family relationships on the grounds of selecting a harmonious family.

"I have only one daughter in my family, Yuanyuan. After she married Lu Min two years ago, the two of us went to live in a school in the provincial capital. We come back often, like during the Qingming Festival and May Day holidays, so we are filial..."

The aunt and the aunt of the Yao family got excited talking, and the parents chatted briefly for more than half an hour.

"Your daughter and son-in-law have been married for two years, and they haven't given you any grandchildren?" Fang Jinshi asked.

At this point, Aunt Yao's face showed bitterness: "It's an injustice to say the least. Yuanyuan and Lu Min are both DINKs. They say that if they don't have children, they will live a happier life."

"This is really rare, but young people nowadays have many lifestyles." Fang Jinshi smoothed things over.

"Maybe it's just the mentality of the past two years. The children will naturally get better as they get older." What the neighborhood committee aunt said was obviously more in line with Aunt Yao's thoughts, and the two immediately started talking about having children.

After talking a lot, they also got an unexpected gain.

Lu Min and Yao Yuan went for a physical examination before getting married, and it was confirmed that Lu Min had no male hidden dangers.

After finishing the visit here, Fang Jinshi immediately called Ying Mingyu and informed them that the direction was not correct.

Despite this, they still wanted to meet Lu Min after he came back, maybe he could give some information about Wei Zishan or Liu Sisi.

After hearing this, Luo Yin clicked his tongue several times: "You are really right, you crow's mouth."

"What should we do next? There are bottlenecks everywhere?" Luo Yin was a little at a loss. He didn't expect that the correlation between the three deceased people was so weak.

"Check the files and look for other ways out."

Luo Yin thought for a moment and nodded: "Did you promise a little girl this morning that you would let her go to the front line tomorrow, but you turned back to look for the file? Is this a empty promise?"

"The progress of the case is not under my control." Ying Mingyu didn't really want to deceive Liu Minmin. It was because he had no choice but to move forward now that he had found out.

During the meeting in the evening, Liu Minmin was not unhappy when she heard about this.

"Master, you need to look for the files together. I divided them into categories before, and I will give them to you when the time comes."
