When the operation began, Zhou Xun led people to the door of Huang Zhiqiang's room and knocked on the door. He pretended to be the owner downstairs and forced the door to be opened on the grounds of water leakage.Among the five people present, a blond-haired man was spotted sneaking away, and Zhou Xun followed him all the way.Guan Hongfeng was telling Han Bin downstairs that there were too many doubts about his brother's case, when he suddenly heard something unusual in the stairwell.Seeing the fleeing person, Guan Hongfeng rushed from the door to trap the person. The person pushed him away hard, causing Guan Hongfeng to be hit in the leg. Fortunately, Zhao Xincheng appeared in time to arrest the person.

Five people were taken into the interrogation room, and none of them let go.Zhao Qian searched Huang Zhiqiang's home and found that the cash serial number matched Cao Yanru's money.The witnesses and physical evidence are all in place, but the only thing missing is information about the killer.They found a message from an anonymous person on Huang Zhiqiang's mobile phone, asking Huang Zhiqiang for the reward for killing.Zhou Xun called an anonymous person and the other person asked for 200,000.Zhou Xun, as Huang Zhiqiang's younger brother, agreed to do the transaction near the trash can in Xiangyang Community, and then put the cash in the trash can.

The police observed that a rented Chery had been wandering near the trash can. After investigating the rental car information, they confirmed the name of the murderer, and Zhou Xun arrested him on the spot.

Zhou Xun asked Haigang District not to inform the outside world of the case-solving information for the time being, while Guan Hongfeng wanted to invite the major media in Tianjin and Hong Kong to cooperate with them and let them spread some false news to the murderer so that he could relax psychologically.

The Physical Evidence Identification Center has achieved preliminary results in processing the video imaging of the Jetta. Guan Hongyu felt that he would not watch it if there was no significant progress, so he asked them to send the video directly.However, he suddenly asked Zhao Qian, if the scope of monitoring was continuously expanded, couldn't the Jetta's entire route that night be restored?Zhao Qian replied that as the search scope continued to expand, the workload would increase exponentially. She felt it was a bit strange for Guan Hongfeng to ask such an idiotic question.When Guan Hongyu asked how many years the surveillance video would be kept, Zhao Qian became even more suspicious. Guan Hongfeng had told her personally that the period of five years was five years.Guan Hongyu looked embarrassed, laughed and said that his memory was not good and left.Then, in the name of Guan Hongfeng, he asked the Traffic Management Bureau to obtain the surveillance video of the community on the night of the murder case.

Han Bin discovered that the murderer did not change his technique between the first and last crimes, which logically should not be the case.Guan Hongfeng also raised questions, and Zhao Xincheng speculated whether the murderer had committed other types of crimes before, but did not hurt anyone, so he was not screened out.Han Bin knew that the initial screening scope was limited to heavy rain, late at night, and trysts with men and women, and concluded that there must be a screening error, so the murderer's first case was not among these four cases, and they should re-screen.

The Physical Evidence Identification Center urged people to watch the Jetta video again. Zhao Qian asked if she could send it via email. Zhou Shutong told her that doing so would violate confidentiality regulations.Guan Hongfeng made mistakes in small things one after another today, which made Zhao Qian more suspicious.

Wang Zhige received Guan Hongfeng and Han Bin, but the highly sharpened video still looked blurry.Wang Zhige asked if the murderer had been arrested, and Han Bin replied that he had indeed been arrested. This time he came to confirm the specific details.During this period, Han Bin noticed that Wang Zhige washed his hands with laundry detergent after shaking hands with Guan Hongfeng. When they left, Wang Zhige stuffed his hands into his pockets and refused to stretch them out to shake hands and say goodbye. Moreover, everyone's desk in the office was meticulously organized, almostTo the point of obsessive-compulsive disorder, Han Bin suddenly became suspicious of Wang Zhige.

On the way back, Han Bin asked about Guan Hongfeng's initiative to talk about Guan Hongyu's case that day. Guan Hongfeng admitted that it was because he thought Han Bin could help them.When Han Bin asked him about the scars on his face, Guan Hongfeng slowly told him.

Two years ago, when he was the captain of the criminal investigation detachment, he led Zhou Xun and Wu Lingling on a mission to arrest arms smugglers.The bandit leader that time was a woman known as Sister Xia. She was ruthless and well-known on the road.At that time, Sister Xia seemed to know that the police were coming, so she sped up the transfer. In order to prevent them from running away before police reinforcements, Guan Hongfeng interfered with them with only three people.However, Sister Xia had a large number of people and sufficient weapons and equipment, so the three of them could only focus on escaping.When Guan Hongfeng hid in a container, he was discovered by two of Sister Xia's men. One of the men trapped Guan Hongfeng and slashed his face with a knife. Only then did he have the look on the right half of his face.The scar looked ferocious, but fortunately Guan Hongfeng picked up the gangster's gun and killed the man.

Guan Hongfeng closed his eyes tightly, as if he didn't want to think about that painful night again.Han Bin saw that he didn't look good, so he asked, had the case been solved?Guan Hongfeng only remembered that after he shot the subordinate, his gun was picked up by someone unknown. When he found someone outside, he shot out of the container, but it was his colleague Wu Lingling who was shot.At that time, Wu Lingling was not dead after being shot, but then Sister Xia drove her car directly and ran over Wu Lingling's body, and Wu Lingling died immediately.From then on, he developed a phobia of the dark and kept seeing Wu Lingling in hallucinations.He didn't tell Han Bin any of this.He replied calmly, broken.

Han Bin suddenly said that maybe the murder case was not aimed at Guan Hongyu, but the implication was that it was aimed at Guan Hongfeng.Guan Hongfeng might have thought of this a long time ago, so he didn't have much reaction when Han Bin said this. Han Bin saw that he didn't want to answer and had no choice but to leave it alone.

During the re-screening, a case from five years ago was discovered. The location was not in the car, and there was no characteristic of a man and a woman in a late night rainstorm, but the scene was equally clean.The victim, Lu Siping, was killed at the Express Hotel, where he had checked into a room with a woman that day.The murderer tidied the room before leaving. The house was clean and tidy, except that Lu Siping died tragically, and the whereabouts of the woman who rented the room remained unknown.Guan Hongfeng confirmed that this case was the first of Li Dishen's cases.

Police investigation revealed that Lu Siping had been detained by Xicheng District for extortion. At that time, he had an accomplice named Gao Liang, who was serving his sentence in Jinggang Prison.Zhou Xun, Guan Hongfeng and Han Bin went to visit the prison. Gao Liang revealed that he and Lu Siping were detained because they pretended to be joint defense to catch the field artillery.However, he never succeeded, but Lu Siping succeeded once, and the man who shot the field gun was a university teacher. Lu Siping asked the man for money several times after that.More importantly, Gao Liang recalled that the university teacher drove a Jetta.
