Detective from the future

Chapter 5 Microexpression Analysis

Street Park.

When Han Bin arrived at the scene, a cordon was already set up around him.

There were a lot of people watching the morning exercise outside.

Zeng Ping, Li Hui, and Zhao Ming have already arrived at the scene.

Han Bin looked around: "Team Zeng, what's the situation at the scene?"

"The victim, Zheng Wen, 31 years old, is a teacher. She was jogging in a park in the middle of the street at around 08:30 last night when she was stunned from behind."

"Is this the position?" Han Bin pointed to the marked position.

Zeng Ping nodded: "She was dragged to the path next to the bushes, and then was violated. She woke up at four in the morning and called the police."

"How is the victim?"

"It's okay, I asked Tian Li to take her back to the bureau."

"Did she see the suspect?"

"The suspect should have been hiding beside the bushes at the time. After she ran over, she was controlled and dazed from behind. She didn't see the suspect's appearance."

Han Bin thought for a moment: "Didn't you hear anything unusual?"

"She listens to music with headphones on when she runs at night."

"Has the suspect left any evidence?"

"White genetic material and two unknown hairs were found on the victim's thigh, which have been sent for identification." Zeng Ping said.

"Isn't it enough to live together." Li Hui spread his hands.

"The DNA database can be compared best, but if you can't, you have to find other clues." Zeng Ping instructed: "Li Hui, you can ask the staff of the park and the people of the morning exercise."

"Zhao Ming, look for nearby surveillance cameras to see if there are any suspicious persons."

"Han Bin, check the scene to see if there are any new clues."

"Yes." Everyone agreed.

……

Everyone split up and got busy all morning.

At two o'clock in the afternoon, return to the police office for a meeting.

Zeng Ping sat on the table: "Tell me, I have found something."

"The victim has already asked all the questions, but she is still a little unstable. I asked her to rest in the reception room." Tian Li said.

"There are no obvious footprints at the crime scene, and there are no obvious climbing marks around the park." Han Bin found no clues.

"What about monitoring?"

"There are surveillance cameras at the front and rear gates of the park. There are many people entering and leaving. It is difficult to check the identities one by one. I have copied the surveillance cameras and can check them at any time." Zhao Ming shook the hard drive in his hand.

"Li Hui, how are you over there?"

"Team Zeng, most of the staff in the park are off work at night. There are only two gatekeepers, and they didn't find anything unusual." Li Hui said.

"Does the morning exercise crowd have any clues?"

"The morning exercisers and the night runners are not the same group at all." Li Hui showed a wry smile.

"That means, there are no new clues in the case." Zeng Ping frowned and took out a box of Yuxi to distribute to everyone.

Han Bin lit a cigarette and took a sip: "Is there any news from the trace inspection? There is a result of the DNA comparison, so there is no need to mess around."

"Tian Li, go to the trace examination room and ask."

……

Not long after, Tian Li came back, followed by a man with glasses and a white coat.

"Yo, glasses are rare, finally willing to leave the laboratory." Zeng Ping said with a smile.

The man held up his glasses with his fingers: "Team Zeng, I specially reported the progress of the case to you. If you say so, I can leave."

"Come back, I'm joking with you."

The man nicknamed glasses, Lu Wen, is a technician in the mark inspection room and one of the few nearsighted people in the police station.

"The suspect left little evidence at the scene. He only collected white genetic material and two hairs. The genetic material has been extracted and sent to the DNA database for comparison."

Han Bin flicked the ashtray: "How did the suspect get stunned?"

"Ether."

Zeng Ping frowned: "Ether is controlled, where did he get it?"

"That's your job." Reuven shrugged.

Showing a look that has nothing to do with me.

"Have no valid fingerprints of the suspect been collected?" Han Bin asked.

"No."

"I asked the victim. When she was dazed, she felt that the suspect should be wearing gloves. As for what happened next, she didn't know." Tian Li said.

Zeng Ping handed Lu Wen a cigarette: "How long will it take for the DNA comparison results to come out?"

"It's hard to say, depending on luck, it may not be possible to compare successfully." Lu Wen declined cigarettes: "Thank you, I quit."

"When there is news, notify me as soon as possible." Zeng Ping said.

"Okay." Lu Wen responded and left the office of the second group.

Zeng Ping snuffed out the cigarette butt: "Everyone already knows the progress and clues of the case. If you have any ideas, you can talk about it."

"Ether is a contraband and cannot be bought in general pharmacies. The source of the ether can be used as the direction of investigation." Tian Li suggested.

Zhao Ming went on to say: "You can continue to investigate and monitor. People who appeared during the time period of the crime and those who met the conditions for committing the crime are all suspects."

"Visit the people who are exercising at night to see if there are witnesses and new clues." Li Hui added.

Zeng Ping nodded: "The summary is good. The current investigation direction starts from these three points. If there are no other problems, we will start to assign tasks."

"Well, you are waiting for us here." Li Hui smiled wryly.

"I personally investigate the source of ether." Zeng Ping glanced at the crowd: "You four check the surveillance during the day, and go to Jiexin Park at night to investigate and visit the masses."

Li Hui frowned: "This task is too large, what is the investigation method?"

"The time of committing the crime was around 08:30 last night. After this time period, all men who left the park were suspected of committing the crime and were to be investigated," Zeng Ping said.

"Team Zeng, I want to talk to the victim to see if there are any other clues." Han Bin said.

"can."

Zeng Ping warned: "The victim's emotions have not recovered yet, so let Tian Li accompany him."

"Yes."

……

Qindao branch, reception room.

"Squeak..." A door rang.

Tian Li and Han Bin entered the reception room.

An intellectual woman sat on the sofa, with a dignified appearance and a well-proportioned figure, with tears on her face.

"Mr. Zheng."

Zheng Wen raised her head, looked at Tian Li and Han Bin, and nodded slightly.

"Mr. Zheng, this is Officer Han from the Criminal Investigation Team. He wants to ask you some questions." Tian Li made an introduction.

"what is the problem?"

Han Bin sat across from the sofa: "Mr. Zheng, do you often go to Jiexin Park to exercise?"

"Yes."

"Do you usually go alone, or with friends?"

"not sure."

"Have you been followed or spied on when you ran at night?"

"No."

Han Bin continued to ask: "Do you think about it if there are any other clues?"

"No, there are no other clues." Zheng Wen shook her head.

According to microexpression analysis, blunt repetitive questions are typical of lying.

Han Bin frowned, if the victim concealed the clues, it would be very detrimental to the investigation.

"Mr. Zheng, do you have any new clues that you didn't tell the police?"

"I've told the police everything I know." Zheng Wen leaned back and folded her arms.

This is a typical defense and resistance mentality. Han Bin is more certain, and Zheng Wen has concealed the clues.

"I know this matter hurts you a lot, maybe you don't want to recall it, but if you hide the clues, you can't catch the suspect, and he will hurt other people."

Zheng Wen closed her eyes, her expression changed and changed: "He stole my underwear."
