Micro-Expression Analysis

Jiexin Center Park.

When Han Bin arrived at the scene, a cordon had been drawn around.

There were a lot of people doing morning exercises outside.

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

"Chief Zeng, what's the situation?" Han Bin said.

"Victim Zheng Wen, 31, is a teacher. She came in the night at Jiexin Park around 8:30 last night and got hit on the head and fainted."

"Is this the position?" Han Bin asked.

Zeng Ping nodded: "After being fainted, she was dragged to the side next to the bushes and committed a violation. She woke up at four in the morning and called the police."

"How is the victim?"

"Alright, I let Tian Li take her back to the station."

"Did she see the suspect?"

"At the time, the suspect was hiding by the bushes. After she ran over, she was restrained from the back and was confused. She did not see the appearance of the suspect.

"Did she hear anything unusual?" Han Bin asked.

"When she runs at night, she listens to music with headphones."

"Did the suspect leave any evidence?"

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

"Isn't it all alive?" Li Hui said.

"The DNA database, if results are found its best. If you can't compare, you have to find other clues." Zeng Ping ordered: "Li Hui, you enquire the park employees and the morning exercise crowd."

"Zhao Ming, you look for nearby surveillance and there are no suspicious people."

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

"Yes." The crowd affirmed.

...

The crowd broke up and worked all morning.

At 2 p.m., they retreated to the police office for a meeting.

Zeng Ping sat at the table and said, "Tell me what you found."

"The victim's side, all the questions should be asked, but the mood is still unstable, I let her rest in the reception room." Tian Li said.

"There is no obvious footprint at the crime scene, and there are no signs of climbing around the park." Han Bin said.

"What about monitoring?" Zeng Ping asked.

"The front and back doors of the park are monitored, and many people are entering and leaving. It is difficult to check the identity one by one. I have copied the monitoring and can check it at any time." Zhao Ming said.

"Li Hui, how are you over there?"

"Zeng team, the staff of the park at night, most of them are off work, there are only two janitors, they did not find anything abnormal." Li Hui said.

"Are there any clues, from morning exercises crowd?"

"The crowd that comes at night and morning are different." Li Hui spread his hands.

"That said, there is no new clue in the case." Zeng Ping frowned and took out a box of Yuxi cigarettes to distribute to the crowd.

Han Bin lit a cigarette and took a puff, and asked, "Is there any news from the forensic department? The DNA comparison will have results, so there is no need to mess about."

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

...

Not long after, Tian Li returned, followed by a man wearing glasses and a white coat.

"Well, glass-eyes, its rare to see you, finally willing to leave the laboratory." Zeng Ping laughed.

The man put his finger on his glasses and pushed them back: "Zeng chief, I specifically report to you the progress of the case. If you don't want to hear, I will leave."

"Come back, I just joked with you." Zeng Ping Road.

The man nicknamed glass-eyes, Lu Wen, is a technician in the forensic examination room and one of the few short-sighted eyes in the police station.

"The suspect left little evidence at the scene, only white genetic material and two hairs were collected, of which genetic material samples have been extracted and sent to a DNA database for comparison." Lu Wen said.

"How did the suspect faint?" Han Bin asked.

"Chloroform."

"Chloroform is regulated. Where did he get it?" Zeng Ping said.

"That's your job to find." Lu Wen shrugged.

"Did you not find any valid fingerprint?" Han Bin asked.

"No," Lu Wen said.

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

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

"This is hard to say. Depending on luck, it may not be compared successfully." Lu Wen said.

"When I have the news, notify me immediately." Zeng Ping said.

"Yes," Ruben responded and then left.

"Everyone has understood the progress and clues of the case. Any thoughts can be said."

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

"We can continue to investigate and monitor. People who appear during the time of the crime and those who meet the conditions of the crime have certain suspicions." Li Hui said.

"Visit the masses who exercise 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 starts from these three points. If there are no other problems, we will start to arrange the task."

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

"I investigate the involvement where the ether originated." Zeng Ping glanced at the crowd and continued: "The four of you check and monitor the footage during the day, went to Jiexin Park to investigate and visit the crowd at night."

"That's a lot of work. How can I investigate?" Li Hui frowned.

"The crime time was about 8:30 last night. After this period, men who left the park were suspected of committing crimes and should be listed as investigation objects." Zeng Ping said.

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

"Yes," Zeng Ping nodded and advised: "The victim's emotions have not been restored yet. Let Tian Li accompany him."

"Yes."

...

Qindao branch office, 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-shaped figure, with tear marks on her face.

"Ms. Zheng."

Zheng Wen looked up, looking like Tian Li and Han Bin, nodding slightly.

"Mr. Zheng, this is the Korean police officer of the Criminal Investigation Team. He wants to ask you some questions," Tian Li introduced.

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

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

"Yes."

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

"not sure."

"Have you been tracked or peeped when you ran the night before?" Han Bin said.

"No."

"Think about it, are there any other clues?"

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

According to the micro-expression analysis, the stiff repetition problem is typical of lying

Han Bin frowned. If the victim concealed the clues, it would be very unfavorable to the investigation.

"Ms. Zheng, do you still have new clues not reporting to the police?" Han Bin said.

"I told police everything i remember." Zheng Wen leaned back, holding her arms at the chest.

This is a typical defensive mentality. Han Bin was more certain, Zheng Wen is hiding the clue.

"I know that this incident hurts you a lot, and you may not want to remember it again, but if you hide the clue, we cannot catch the suspect and he will hurt others." Han Bin said.

Zheng Wen closed her eyes, her gaze intensified and said, "He snatched away my underwear."
