"What's that stranger's name?" Lao Chen asked.

"Anping, thirty years old." Li Ming said.

"Anping?" Lao Chen questioned.

"That's right! He also has another identity, another case Yan An's brother. Li Ming said.

"Immediately investigate Anping's whereabouts on the day of the crime." Lao Chen yelled.

Up to now, through the information he consulted, Lao Chen concluded that this Yan Ping not only has a connection with Yi Shuai's family, but must also have something to do with Aunt Wang.

According to Lao Chen's years of experience in handling cases, the process of the case has probably been clarified, but there is still a lack of evidence.

Without further ado, Lao Chen hurriedly went to the monitoring room of the community to check Yan Ping's recent movements.

Lao Chen had asked other police officers to check and monitor before, but up to now, the police have checked all the surveillance at the entrance of the community and the door of the unit where the crime occurred in the last six hours, and there was no trace of Yan An during this period.

Then I had to continue to investigate the previous surveillance, and at this time Lao Chen already felt very urgent, because the whole case had been linked, and there was almost convincing evidence.

Lao Chen walked out of the monitoring room and looked at his watch, it was already four o'clock in the morning.

This time is the coldest time, and the leather jacket worn by Lao Chen can't stop the wind chill.

While waiting for Li Ming's investigation results, Lao Chen had nothing to do but go back to the car parked in front of the property office building.

After getting into the car, Lao Chen cowered in the cab, at this time Lao Chen seemed to remember something, and when he came here for the first time in the evening, he took Xu Tian and met a guy with high beams on the road.

At that time, although Lao Chen's eyesight was temporarily blind, the person with the car had already been seen clearly by Lao Chen before he turned the corner.

That scene is still vivid, when Lao Chen just hit the steering wheel, about a second later, the opposite car turned on the high beam, the face in the opposite car Lao Chen is very familiar, thinking of this, Lao Chen took out something similar to a mosquito coil from his pocket.

This thing has been half ignited, and there is still some untreated gray matter under the back seat of Lao Chen's car, and at this time in the psychological clinic, Dr. Lin has already shown Xu Tian, and the thing similar to mosquito coil is the medicine that makes Xu Tian hallucinogenic many times.

"You developed this?" Xu Tian asked.

"I don't have that much ability, this is a drug that has not yet been marketed, because its effect is relatively unsuitable for sale, so it has been banned a long time ago, and now it has long been discontinued, and I only have a small part in my hand, and they are all experimental products." Dr. Lim said.

"You dare to use it on me?" Xu Tian felt very angry.

"Don't worry, I am very clear about the dosage of this drug, because I am also one of the developers, and the purpose of this drug was originally to be used for hypnosis to patients, which is equivalent to sleeping aids, but its properties are similar to sleeping pills, so it was banned." Dr. Lim said.

"I'm not interested in this drug." Xu Tian said.

"That'...... What if I told you that Lao Chen had this thing in his car? Are you still interested? ”

"What do you mean? Are you saying that Officer Chen used this thing to calculate me? ”

"That can't be said, we're not calculating you, we're helping you get into a hypnotic state."

"Help me? Didn't you think about feeling guilty when you said this? I don't think it's right for you to do these things on your own. ”

"Are you educating me by that? If you have to understand it that way, then I'll just be the bad guy! ”

"Why did you force Lao Chen's car to stop at night? Don't you know that that's dangerous? Once Lao Chen makes a mistake, overturns the car or hits a pedestrian, how do you want to take this responsibility? ”

"You have occasionally said something that makes me feel inexplicable just now, when did I force Lao Chen to stop driving? Can you make that clearer? ”

"Didn't your assistant do it?" Xu Tian questioned.

"My assistant? She doesn't have time for that kind of boring thing, and I can tell you for sure that what you just said has nothing to do with my assistant. Dr. Lin categorically denied Xu Tian's doubts.

……

At this time, in Lao Chen's car, Lao Chen, who was wearing a fur coat, was very anxious, because Lao Chen felt a little strange, obviously the medicine that Dr. Lin gave him was not ignited, why did he find half of the ignited drug in the car afterwards?

There is also the person who turned on the high beams to force Lao Chen to stop, Lao Chen has never made it clear, because he is afraid that something will happen to that person, because Lao Chen can't tell who he is at all.

Teacher Jin's mocking face was still echoing in Lao Chen's mind, but Lao Chen also knew very well that Teacher Jin himself should not have done such a thing, and Teacher Jin should have been in the psychological clinic when it happened.

Things got very bad, just as Teacher Jin and Doctor Lin had said to Xu Tian before, they had not ruled out their suspicion of Teacher Jin, especially after this matter was discovered by Lao Chen, Teacher Jin's suspicion was already very obvious.

There is also the incident that happened about a month ago when Lao Chen was entrusted by Xu Tian to hide in the office, when Lao Chen heard someone approaching the office, Lao Chen, who was hiding in Xu Tian's room, could clearly judge that the person walking was a man, but when Lao Chen chased him out, the people he saw were indeed Sitong and Siyan, and this matter has been put aside in Lao Chen's heart.

However, that day, Lao Chen kept an eye on it, and before Lao Chen hid in Xu Tian's room, he once clipped a very small pencil lead in the lock at the gate.

When Lao Chen left the office and approached the door, Lao Chen was very sure that the small pencil lead was not broken, which showed that the man who sneaked into Xu Tian's house had not left at that time, and the two sisters, Sitong and Siyan, had never left the office that night.

Lao Chen didn't tell Xu Tian about this matter, the reason was that Lao Chen didn't want to hinder Xu Tian's case at that time, because this matter was very important to Xu Tian, and Lao Chen wanted to find a suitable opportunity to tell Xu Tian about it.

Just thinking about these irritating things, Li Ming finally called.

"Hey! Li Ming, is the investigation clear? ”

"Team leader! I checked the surveillance video of the traffic department again on the day of the crime, and found that no one was found passing through that area near the scene of Yan An's murder, and there was absolutely nothing wrong with this. ”

"Have you checked Yan Ping's traces?"

"It has been found out that Yan Ping did go out that night, and this matter still has something to do with Yan An more or less."

"What's going on?"
