is also a female teacher, surnamed Tong, named Tong Xin. 37 years old, slightly younger than Huang Xueling. Tong Xin is a psychology teacher at the school, who is usually responsible for teaching psychology courses and sitting in the counseling room to provide psychological counseling and counseling to students.

Is Tong Xin's disappearance related to Huang Xueling's death?

It's still uncertain, because Tong Xin didn't die and didn't come back, and no one knows why she can't be contacted.

But if she really has an accident, then it will be too late.

In the same school, accidents occur one after another, and the possibility of combining cases cannot be ruled out.

The reason why Huang Xueling's death was discovered a few days later was because she and her husband did not have a good relationship, and secondly, her working hours were relatively free, with many holidays, and she had a precedent of not coming to work in the past and submitting a leave application later.

If the murderer is sure that Huang Xueling will disappear and no one will find out immediately, then what is the purpose of his attack on Tong Xin?

Tong Xin didn't go home after class that day, and she didn't come back overnight, and her husband called the police the next day.

Would a cautious murderer be so sloppy in the second crime?

Or is it that this murderer has other plans, and what he likes is older women, which is a common trait of these two people. The age is not young anymore, and the children are all there.

But why is it still a teacher in this school, doesn't this attract more attention from the police?

While thinking about it, Lu Cheng rushed to the school again with the team to investigate.

The school's recent surveillance footage has been called up, focusing on whether the two teachers have been in contact with any suspicious people and whether there are any strange vehicles entering the school.

saw Tong Xin on the display screen walking out of the school gate safely at the end of the day. Lu Cheng thought of something, he turned to Xiaomei and said, "Xiaomei, ask Tong Xin's husband, does he know what other places Tong Xin might go after work?" ”

"Except to go home?"

"Yes, except to go home."

Xiaomei immediately took the order and dialed Tong Xin's husband's phone.

Tong Xin didn't have an accident at school, so it must be something outside the school.

I have always focused on the identity of the two teachers as teachers in the same school, and have been looking for their common ground around the school, trying to find their intersection in the school.

However, is it possible that that intersection could be outside of school?

This rhetorical question woke up Lu Cheng.

So he asked Xiaomei to investigate Tong Xin's activities outside the school.

At this time, Lu Cheng received another piece of news.

An off-campus psychological counseling agency called to ask Tong Xin's husband if he was at school, and the person in charge of the institution called Tong Xin's number, but it was not connected.

At this time, her husband remembered that in addition to teaching psychology courses at school, Tong Xin also went to a psychological institution outside the school from time to time to participate in some social psychological counseling, public welfare activities, etc.

With this news, Lu Cheng immediately asked Xiaomei to investigate whether Tong Xin had been to a psychological institution on the night of her disappearance, and whether Huang Xueling had anything to do with this psychological institution.

The answer to both questions is yes.

Huang Xueling has also participated in activities in this organization, and the two of them have also had work exchanges in this area.

This is something Lu Cheng did not expect.

The investigation that followed was like a refueled car, moving forward exceptionally smoothly.

After investigation, on the night of Tong Xin's disappearance, there was indeed a vehicle patrolling near the institution, and then stopped in a relatively remote location, and was not directly captured by the surveillance. But the license plate has clearly flashed on the surveillance video, Yu A3780D, is a foreign license plate. It stopped on the way home for Tong Xin, and after leaving the psychological institution, it went to the north of the city, which was consistent with the direction of the upper reaches of the Lin River, and the driver was dressed tightly and wore sunglasses, which made people unable to distinguish their appearance and had a strong sense of anti-investigation. Based on the above, it was determined that this person was a major suspect.

Based on the license plate number, the investigation team quickly found out the information of the owner.

Li Weiming, male, 27 years old, a migrant worker from other places, has moved bricks at a construction site, has also worked as a second-hand dealer, has resold a lot of things, the truth is mixed, the income is not stable, there is no criminal record that is too bad, he often goes to bars, and has a history of drug abuse.

When the police found him, he was shirtless in his rental house, wearing big pants and holding a bottle of drink, completely unprepared.

If it weren't for Lu Cheng's offer to enter his room to take a look, probably no one would have noticed Li Weiming's abnormality.

He didn't speak at first, and thought for a moment, as if he was a little embarrassed, but he didn't dare to categorically refuse the police.

This strengthened Lu Cheng's determination to go in and see it in person.

Unexpectedly, before he had walked a few steps, he saw a woman in the living room who was also dressed in revealing clothes.

The woman was slumped on the sofa, twisting her waist incessantly, her eyes were not focused, and she did not notice that a stranger had entered, in short, it was very abnormal, and the experienced anti-narcotics police could tell at a glance that she was taking drugs.

The coffee table in front of the sofa was still littered with the remaining white powder.

Li Weiming said that it was his girlfriend Sun Hui, and he did not defend the fact that they were taking drugs.

Lu Cheng also brought Sun Hui into the police station, and he also had something to ask her before handing her over to the anti-narcotics police.

Lu Cheng interrogated the two of them separately.

Lu Cheng first asked Li Mingwei where he went on the night of Tong Xin's disappearance, and at the same time asked where his car was parked, and asked the fat man to take the rest of the investigators to find his car and see what abnormalities and clues were on the car.

"I didn't go anywhere that night," he said, as if he wasn't impressed by the events of the previous night, scratching his hair and saying, "It's with my girlfriend, we're at home." ”

Lu Cheng also asked Xiaomei to check the identity information of Li Weiming's girlfriend, who is also a migrant worker in other places, but her job is relatively stable, and she is currently working as a waiter in a hotel. After dating Li Weiming, he became addicted to drugs.

"That is, your girlfriend is your only witness?"

Li Weiming thought about it and nodded.

"You haven't driven out all night?"

Li Weiming thought about it again and shook his head.

"Do you recognize these two women?"

Lu Cheng showed him the photos of Tong Xin and Huang Xueling and observed his expressions.

He looked at it carefully, but still shook his head.

Li Weiming is the owner of the car, and there is nothing wrong with that, he said that he has been staying at home, and his girlfriend has testified and shown him a photo of the victim, and he has no special expression or reaction.

Either he is telling the truth, or he is a person who is extremely good at lying.

"Is anyone else likely to drive your car?"

He said that he couldn't think of it for the time being, and the car was always driven by himself.

Things did not go as expected, and Li Weiming did not admit his guilt until there was further evidence to prove it.

Or focus on the investigation from two aspects, either to find out some evidence from his car, or to ask something from Sun Hui's mouth. Since Li Weiming is confident that Sun Hui will testify against him, Sun Hui must also be taken into account, and the possibility of a partnership cannot be ruled out.

What makes people's heads big is that after Sun Hui took drugs, the effect of drugs still exists, her spirit has been in a trance, she can't ask anything, and when she is fully sober, it may be more than tonight.

However, Tong Xin is still missing.

Every minute and every second is a passage of life for this missing person whose fate is uncertain.

Lu Cheng, who had always been calm, was also a little anxious at this time, he took out a cigarette and lit it, and took a sharp breath.

Await. What else can you do but wait?

What is important now is not the evidence, but to find the missing Tong Xin as soon as possible, and to find Tong Xin, you need to let the murderer speak. Let the murderer tell where Tong Xin is.

If Li Weiming is the murderer, how can he be made to speak?

Even if he finds evidence and puts it in front of Li Weiming, can he guarantee that he will definitely speak?

If he just looks at us and is anxious, if he is just a calm madman......

Thinking of this layer, Lu Cheng couldn't sit still.

Is there any other way......

He thought of many people, Qin Rongguang, and Xu Guangyuan.

He knew that if he informed Xu Guangyuan of the difficulties he was encountering at this time, Xu Guangyuan would take time out to help him even if he was busy. And Qin Rongguang will think that he is going to the doctor when he is sick.

But now, there was a third person in his mind.

A third person independent of Xu Guangyuan and Qin Rongguang.

They never crossed paths, but his sentence: "The murderer cares about her son. Palace", at this time was haunting Lu Cheng's ears. And his twinkling eyes.

Lu Cheng had never seen such impressive eyes. There was a certainty in those eyes that he had never seen in the eyes of anyone else.

He picked up his phone and found Xu Guangyuan's name in the list of contacts. But moments before dialing the number, he stopped.

He looked through the address book again and found the name of Deputy Director Lu Jiyang.

He knew that Lu Ju had talked to Xu Guangyuan about technical cooperation, and he wanted to know if Xu Guangyuan had mentioned Shen Ran to him, or if he had simply taken Shen Ran to meet Lu Ju.

He wanted to take a gamble.

"Lu Ju, I'm Lu Cheng, now I want to trouble you, I want to ask, do you know Shen Ran?"

When Lu Cheng was making this call, Xiaomei passed by him.

She stopped and listened for a few minutes, and after Lu Cheng hung up the phone, she asked puzzledly: "Team Lu, why did you go around such a big bend to ask Lu Ju, isn't it more direct to ask Professor Xu?" ”

Team Lu spread his hands: "It's very simple, I just want to bypass Xu Guangyuan, as for why I want to bypass Xu Guangyuan...... Go to your own senses. ”

He didn't explain much, turned around and went to his own place, leaving Xiaomei alone to wonder.

"What do you mean? Why is the Lu team mysterious, he wants to find Shen Ran, but he doesn't want Xu Guangyuan to know, what does this mean, does he want to dig the foot of the wall? ”

Xiaomei felt that she had discovered something terrible, and quickly covered her mouth.

Although Lu Cheng didn't treat her as a woman, Xiaomei still has the characteristics common to all girls, gossip.

She is afraid that if she is not careful, she will be heard by others about her "evil thoughts".

"Phew...... What digging into the wall, it's too ugly, it's just a normal meeting, an appointment, yes, it's just a date......" She muttered to herself, and her heart was much more steady.

In fact, the reason why Lu Cheng wanted to contact Shen Ran privately was that it was simple and indeed very simple, that is, when he saw Shen Ran's desire to speak and stop that day, as well as Xu Guangyuan's reaction, it was obvious that Xu Guangyuan wanted to stop him from saying anything.

Why Xu Guangyuan wanted to stop Shen Ran, Lu Cheng didn't know, but he knew that only by letting Shen Ran say those unfinished words could he judge whether Shen Ran was helpful to them or not.

Lu Ju really remembered Shen Ran's phone call.

Lu Cheng called this number, and the phone was connected.

A soft voice came from the earpiece, "Hey." ”

"Hello, I'm Lu Cheng."
