Five Micro-Expression 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.

"Team Zeng, what's the situation?" Han Bin asked.

"The victim Zheng Wen, 31 years old, is a teacher. Last night, around 8:30 p.m., she was running at night in the park in the middle of the street. She was stunned from behind and violated."

"Is this the location?" Han Bin asked.

Zeng Ping nodded: "After being dazed, he dragged him to the path beside the bushes, and committed the assault. He 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."

"Didn't hear anything unusual?" Han Bin asked.

"When she ran at night, she listened to music with headphones on."

"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 this all alive." Li Hui said.

"The DNA database can be compared best, but if it can't be compared, we 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 surveillance cameras nearby 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 and said, "Let's talk about it, you have found something."

"On the victim's side, I have asked all the questions that should be asked, 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 said.

"What about monitoring?" Zeng Ping asked.

"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 said.

"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.

"Morning exercise crowd, do you have any clues?"

"The morning exercisers and the night runners are not the same group at all." Li Hui spread his hands.

"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, took a sip and asked, "Is there any news from the trace inspection? The DNA comparison results, so there's 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." Zeng Ping said.

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," Lu Wen said.

"How did the suspect get dazed?" Han Bin asked.

"Ether."

"Ether is controlled, where did he get it?" Zeng Ping said.

"That's your job." Reuven shrugged.

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

"No." Lu Wen said.

"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.

"How long will it take for the DNA comparison to come out?" Zeng Ping asked.

"It's hard to say, depending on luck, it may not be possible to compare successfully." Lu Wen said.

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

"Yes." Lu Wen responded and left.

"Everyone has already understood the progress and clues of the case. If you have any ideas, you can talk about it." Zeng Ping said.

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

"You can continue to investigate and monitor. People who appeared during the time period of the crime and those who meet the conditions for committing the crime are all suspected." Li Hui said.

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

Zeng Ping nodded: "It's a good summary. The current investigation direction really 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 will investigate the source of the ether myself." Zeng Ping glanced at the crowd and continued, "The four of you will check the surveillance during the day, and go to Jiexin Park at night to investigate and visit the masses."

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

"The time of committing the crime was around 8:30 last night. After this time period, all men who leave the park are suspected of committing crimes and must be listed as the target of investigation." Zeng Ping said.

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

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

"Yes. "

...

Qindao branch, reception room.

"Squeak..." A muffled sound.

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 introduced.

"What's the problem?" Zheng Wen asked.

Han Bin sat opposite and said, "Mr. Zheng, do you often go to Jiexin Park to exercise?"

"Yes."

"Do you usually go alone or with friends?" Han Bin asked.

"not sure."

"Have you been followed or spied on when you ran last night?" Han Bin asked.

"No."

"If you think about it, are there any other clues?"

"No, there are no other clues." Zheng Wen said.

Stiff, repetitive questions are typical lying, according to microexpression analysis

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?" Han Bin asked.

"I know, I've told the police." 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 that this matter has hurt you a lot. Maybe you don't want to recall it, but if you hide the clues, you won't be able to catch the suspect, and he will hurt other people." Han Bin said.

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