D F T F Chapter 5: Micro expression analysis.

When Han Bin rushed to the scene, specifically to Street Center Park, a cordon had been put in place around the park, and the many early morning sports practitioners were outside the park and turned into onlookers, Zhang Ping, Li Hui, and Zhao Ming have already arrived at the scene.

"Captain Zhang, what's the situation?" Han Bin said.

"The victim, Zheng Wen, is a 31-year-old teacher. She ran at night in Street Center Park around 8:30 am last night. Someone has knocked her out from behind and violently assaulted her."

“Is this the place of aggression?” Han Bin asked.

Zhang Ping nodded: "After knocking her out, he dragged her away from the small road next to the bushes, and there he committed the rape. She woke up shortly after four in the morning and used her phone to call the police."

"How is the victim?"

"She is fine, I asked Tian Li to take her back to the station."

"Has she seen the suspect?" "

“The suspect should have been hiding near the bushes. When she was running she was controlled and dizzy from behind. She did not see the appearance of the suspect."

"Didn't she hear any unusual movement?" Han Bin asked.

"When she was running at night, she wore headphones to listen to songs."

"Did the suspect leave any clues?"

"White genetic fluid and two unknown hairs were found on the victim's thigh and were sent to the lab for identification." Zhang Ping said.

"That's all for the moment." Li Hui said.

"The DNA database is the best to compare. If we can't compare, we have to find other clues." Zhang Ping said and then added: "Li Hui, you can question the park employees and morning sports exercisers."

"Zhao Ming, you look at the surveillance cameras nearby and see if there is a suspicious person. Han Bin, look at the scene to see if there are any new clues."

Everyone answered: "Yes, Captain." 

And then they parted ways and worked all morning.

At two in the afternoon, they returned to the police station for a meeting. Zhang Ping sat down at the table and said: "Let's talk about it, what you have found?"

"On the victim's side, all questions should be postponed, as she is still a little unstable. I let her rest in the reception hall." Tian Li said.

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

“What about monitoring?” Zhang Ping asked.

"The front and back gates of the park are monitored, and there are a lot of people coming in and out. It is very difficult to verify identities one by one. I have copied the recordings from the surveillance cameras and can verify them at any time." Zhao Ming said.

"Li Hui, how are you on your side?"

“Captain Zhang, most of the park workers were off work at night. There was only one guard at each gate, and neither of them noticed anything unusual.” Li Hui said.

"Did the morning sports practitioners notice anything?"

"This is not a group of people doing morning exercises and night running." Li Hui spread his hands.

"That is to say, there are no new clues in the case." Zhang Ping frowned, took out a box of Yuxi cigarettes, and distributed one cigarette to everyone.

Han Bin lit the cigarette, took a puff, and asked, "Is there any news from the lab with the inspection of the samples? Does the DNA comparison have a result?"

“There is no need to disturb us. Tian Li has gone to the lab to inspect the results and request the report."

Soon after Tian Li's return and the meeting started, a man wearing glasses and in a white coat followed.

"Yeah, finally, the Glasses, is ready to leave the lab." Zhang Ping said with a smile.

The man put his finger on his glasses and said: "Captain Zhang, I am specifically reporting the progress of the case to you. If you mean that, I will leave."

"Come back, I'm kidding with you." Zhang Ping said.

The man nicknamed the Glasses, Lu Wen, is a lab technician and one of the few short-sighted people in the police station.

"The suspect left little evidence at the scene, only white genetic fluid and two hairs were collected, from which genetic fluid was extracted and sent to the DNA database for comparison." Lu Wen said.

"How did the suspect knock out the victim?" Han Bin asked.

"Using diethyl ether."

"Diethyl ether is regulated, where did he get it?" Zhang Ping said.

"It's your job." Lu Wen shrugged.

"No valid fingerprint was collected?" Han Bin asked.

"No." Lu Wen said.

"I asked the victim what she remembers before passing out, and she replied that she thought the suspect was wearing gloves. As for the rest, she didn't know." Tian Li said.

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

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

"As soon as you have news, let me know as soon as possible." Zhang Ping said.

"Yes." Lu Wen replied, and then left.

"Everyone has already figured out the progress in the clues of the case. If you have any ideas, you can talk about it." Zhang Ping said.

"Diethyl ether is smuggled, and it is not available in regular drugstores. We can use the source of the diethyl ether as a direction for investigation." Tian Li said.

"You can continue to investigate and monitor. People who appeared at the time of the crime and those who qualified to commit the crime are all under suspicion." Li Hui said.

“Visit the people who exercised at night to see if there are any witnesses and new clues.” Li Hui said.

Zhang Ping nodded: "This is a good summary. The current direction of the investigation really starts from these three points. If there are no other problems, we will start to distribute the tasks."

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

"I will personally investigate the line where the diethyl ether comes from." Zhang Ping glanced at the crowd and continued, "You four check the record of surveillance cameras during the day, and go to Street Center Park to investigate and visit the crowd who played sports at night."

"This task is too heavy, what is the method of proceeding?" Li Hui frowned.

"The time of the crime was around 8:30 Am last night. After that time, all of the men who left the park are suspected of having committed the crime, and they are all listed as targets of investigation." Zhang Ping said.

“Captain Zhang, I want to talk to the victim and see if there are any other clues.” Han Bin said.

At the Qingdao branch, at the reception hall, there was a muffled sound "Crack..." this is the sound of the door handle when it is opened by Tian Li and she entered with Han Bin into the reception room.

Han Bin saw an intellectual woman with a dignified appearance and a well-proportioned figure, with tears still on her face while sitting on the sofa.

"Mrs. Zheng."

Zheng Wen lifted his head, looked at Tian Li and Han Bin, and nodded slightly.

"Mrs. Zheng, this is the Korean police officer of the Second Group of the Third Criminal Investigation Team. He wants to ask you a few questions." introduced Tian Li.

"What is the problem?" Zheng Wen said.

Han Bin sat across from her and said, "Ms. Zheng, do you often go to Street Park to exercise?"

"Yes."

“Do you usually go there alone or with your friends?” Han Bin said.

"Sometimes alone and sometimes with friends"

"Were you followed or spied on when you ran the night before?" Han Bin said.

"No."

"Think about it, is there something else you haven't said?"

“No, there are no other clues,” Zheng Wen said.

Strict and direct responses are typical of lying, according to the analysis of subtle expressions.

Han Bin frowned. If the victim hid clues, it would be very detrimental to the investigation.

"Mrs. Zheng, do you have any new clues that you haven't told the police?" Han Bin said.

"I know, I told the police everything." Zheng Wen leaned back and crossed his arms in front of his chest.

This is a typical defensive resistance mentality, and Han Bin is even more certain, Zheng Wen is hiding something.

"I know this incident hurt you a lot, maybe you don't want to remember it anymore, but if you hide the clues we won't be able to catch the suspect, and he will continue to rape other women." Han Bin mentioned.

Zheng Wen closed her eyes, her expression changed again and again, and said: "He took my inner clothes with him."
