Huang Wei sighed as if he didn't want to remember.
Han Bin had been observing the man. His expression was normal, but when Han Bin asked, "Did you notice the three cars parked about ten meters away from the body?", the man was stunned.
Huang Wei hesitated for a moment, then shook his head and answered, "I have some impression of them."
Shaking one's head usually meant denial, but having some impression of them was a definite answer.
Inconsistency between body language and body language was also a sign of lying.
In other words, the sentence "have some impression of them" was not credible.
China's culture was broad and profound. There were two opposite meanings of "have some impression of them." One was that one had no impression of them, and the other was that one had a deep impression of them.
If Huang Wei had no impression of them, Han Bin felt that there was no need for him to lie. He could have just said that he had no impression of them.
Therefore, Han Bin was more inclined to believe that Huang Wei had a deep impression of the three cars.
Then, Han Bin asked again, "Did you see a Mercedes-Benz?"
Huang Wei answered, "I didn't see it carefully. I was scared out of my wits."
When he said this, his expression did not show any obvious abnormality.
However, Han Bin felt that this should be a lie as well. If Huang Wei had noticed the three cars, the Mercedes-Benz would have been the most obvious.
This also showed that micro-expression was a very complicated subject. It was a battle between consciousness and instinct. Not every lie could be seen through, and not every lie would have obvious characteristics.
The signs that represented lying might not be completely credible. Sometimes, it could be a nervous or habitual action of the other party.
There must be a specific case and a specific analysis. If they wanted to use it in a case, it could only be used as a direction for investigation. They still had to rely on concrete evidence.
If Huang Wei showed signs of lying, Han Bin would investigate.
"Huang Wei, did you notice that the victim was holding something in his hand?" Han Bin asked.
Huang Wei took a deep breath and sighed. "I was too nervous. I can't remember clearly."
"It's okay. Relax. I was not much better than you when I saw a dead person for the first time." Han Bin comforted him and said to Li Hui, "Get a cup and pour some water for Huang Wei."
"Got it." Li Hui responded and poured a cup of warm water for Huang Wei.
"Thank you." Huang Wei nodded and took the cup with both hands.
"Huang Wei, you didn't stay at the scene after you reported the case. Where did you go?" Han Bin continued to ask.
"At that time, I didn't dare to stay at the scene, nor did I dare to go home, so I went to a nearby shopping mall. I wanted to find a place with many people to stay and get rid of the bad luck," Huang Wei said.
"Pfft …" Li Hui couldn't help but laugh. "This is the first time I've heard of such a method to get rid of bad luck."
"I feel more at ease when I go to a crowded place," Huang Wei said.
"Don't be a busybody here. Go check your surveillance." Han Bin pushed Li Hui.
Han Bin and Li Hui had known each other for many years. They often hung out together when they were in university. There was a tacit understanding between the two people.
Li Hui returned to his desk and turned on his computer screen to check the surveillance of the auxiliary road outside Jing 'an Alley. At 6: 46, he saw a man wearing glasses walking on the auxiliary road. It was Huang Wei, who was taking notes on the road.
Li Hui held a cup of tea and looked like he was going to pour some water. He walked behind Huang Wei and gave Han Bin an OK hand gesture.
Han Bin stood up and shook hands with Huang Wei. "Mr. Huang, thank you for cooperating with our work."
"It's my duty. Can I go now?" Huang Wei asked.
"Yes."
Han Bin answered and picked up a business card from the table. He handed it to Huang Wei. "This is my business card. If you remember anything after you go back, you can give me a call."
"Sure." Huang Wei answered and got up to leave the office.
Li Hui sent the other party to the door and then closed the office door. "I checked the CCTV. He left Jing 'an Alley at around 6: 46 pm and followed the auxiliary road to the vicinity of the mall. The one who drove the Mercedes-Benz was not him."
"Let Tian Li investigate the whereabouts of the Mercedes-Benz. You should check the surveillance video at the time of the crime last night to see if there were any suspicious people," Han Bin said.
“OK。”
Han Bin found a map of Jing 'an Alley on the Internet. There were old buildings on both sides of Jing' an Alley. The map showed that there were more than 40 buildings. Each building had three to five units and four to six stories high. The environment was relatively complicated.
Fortunately, the buildings were built in a regular square. They were surrounded by two auxiliary roads and two main streets. They were Jing 'an South Road, Jing' an North Road, Tan Gu West Street, and Jianming Street.
There were 11 forks in Jing 'an Alley, but Han Bin studied them carefully. All the forks would converge into these four streets. Although the terrain was relatively complicated, as long as there was enough time to investigate, there was still a chance to find the suspect's tracks.
Han Bin studied the map and had another layer of worry because the situation in Jing 'an Alley was relatively complicated. It was like a large community. There was basically no public surveillance inside. If the suspect ran to the roof, corridor, or hid in the residents' homes, then the surveillance of the four streets would be difficult to take effect.
The best way was to carry out a thorough investigation of the buildings around Jing 'an Alley. However, it was not enough to rely on the few people in the crime squad. More police forces were needed to complete the investigation in a short time. The crime squad was not familiar with the situation there. The best way was to let the Anping Police Station assist in the investigation.
However, this was not something that Han Bin could decide. It still needed the coordination of the higher-ups. Han Bin went to Zheng Kaixuan's office and proposed his idea in person.
Zheng Kaixuan also agreed with Han Bin's suggestion, but he could not make the decision. The police station director's rank was higher than his. If he made a request for assistance in the investigation and Superintendent Wei was not willing to cooperate, it would be awkward for everyone.
Therefore, Zheng Kaixuan could only report to Dai Minghan. Han Bin could only go back and wait for the news …
Han Bin had just returned to the office door when he heard voices inside. When he opened the door, Zhao Ming and Sun Xiaopeng had returned.
"Brother Bin."
"Team Leader." The two of them greeted.
"How's the investigation at the communication company?" Han Bin asked.
"The victim's phone has been turned off. We asked the communication company for the victim's recent call records. At the same time, we also found the victim's wife. We have contacted her to come identify the body."
"Check Fan Zhenye's recent contacts and see if there are any suspicious people," Han Bin ordered.
"Yes."
Knock, knock … At that moment, there was a series of knocks on the door.
"Please come in."
Creak … Medical Examiner Wu Xia pushed the door open and walked in.
"Team Leader Han, the autopsy report is out."
"Medical Examiner Wu, please take a seat." Han Bin made an inviting gesture and had someone pour a cup of water for Wu Xia.
"Thank you." Medical Examiner Wu accepted the disposable paper cup and drank a mouthful of water to moisten her throat. "Do you want to read the autopsy report yourself or listen to my summary?"
"Please tell us the main points. This thing is a bit difficult to read," Han Bin said with a smile.
Wu Xia raised a finger. "First, the victim's exact time of death was around 9 pm last night."
Han Bin nodded. This was consistent with the time they saw from the surveillance camera that the victim entered Jing 'an Alley.
"Second, the murder weapon used to kill Fan Zhenye was a short and sharp dagger. The blade was about 12 centimeters long and the widest part was about 2 centimeters. The blade of the dagger had a certain curve, and it was a bit like a willow leaf."
Han Bin wrote it down in his notebook. This was very important.
"Third, I extracted some dandruff tissue from the victim's fingernails."
"Is it a suspect's dandruff?" Li Hui asked.
"I can't be sure about this. You will need to investigate it yourself." Wu Xia shrugged.
Han Bin thought for a moment and pointed at Li Hui. "Send the glass cup used by Huang Wei to the forensics team for examination."
Li Hui made an OK gesture. "Understood."
