When Guan Hongyu came to the bar, Liu Yin directly called him Guan Hongyu, and Guan Hongyu was shocked.Liu Yin confessed that she already knew the secrets of Guan Hongfeng and Guan Hongyu. She stated that she believed that Guan Hongyu would not kill anyone.Guan Hongyu saw that he was so frank, so he had nothing to hide.It happened to be very cloudy, so Guan Hongfeng sent a text message to Guan Hongyu asking him to find a place to hand over in advance.Guan Hongyu decisively replied that he was at the Yinsu Bar, and Guan Hongfeng rushed to the bar to meet him.Liu Yin brought Guan Hongfeng a blanket for the night, and Guan Hongyu told his brother that she already knew that the two had handed over the case. Guan Hongfeng didn't see anything strange about Liu Yin, so he agreed to rest here.Dong Han's editor-in-chief went to bail with the district chief's documents, and Liu Changyong released him.

As soon as Dong Han left, news about the case spread overwhelmingly on the Internet. Even the fact that Guan Hongfeng was Guan Hongyu's brother and that he resigned and came back to handle the case was also widely spread. The 2.13 tragedy was also brought up to talk about.For a time, there was an endless stream of reporters coming to the police station for interviews.Guan Hongfeng withdrew early today, and he did not participate in the evidence extraction. In order to prevent Guan Hongyu from having nothing to say about the case and arousing Zhou Xun's suspicion, Guan Hongfeng placed a micro bug in Guan Hongyu's ear.During the process of sorting out the case, Guan Hongfeng listened carefully to the various clues coming from the bug, and he guided Guan Hongyu's speech and behavior one by one.There was too little evidence at the scene. The cell phone was knocked over under the car, and the video only recorded the murderer tidying up at the scene for twelve minutes after the murder.Within these twelve minutes, the murderer restored the seats and arranged the victim's clothes.

Neither Li Dican nor Chang Aai's jewelry and wallets were lost, and Chang Aai showed no signs of being violated.This behavior of seeking neither wealth nor sex left everyone confused.Guan Hongfeng left Zhou Xun behind after sorting out the case. According to Guan Hongyu, the murderer had a certain degree of obsessive-compulsive disorder. Heavy rain, late at night, and trysts were characteristics of the crime. The clues that the murderer skillfully cleaned up the scene showed that he wasA habitual offender, but there have been no such cases in Changfeng District in recent years.Zhou Xun decided to go to the city bureau to mobilize the police force and check whether there were similar but unsolved cases in the entire city within five years.At this time, Director Gu of the police station suddenly visited and Zhou Xun was called away.The Municipal Bureau already knew through the news that Guan Hongfeng was back to investigate the case. The Municipal Bureau asked Bureau Gu to give an explanation, and Bureau Gu had no choice but to come to the detachment.

Director Gu ordered him to patrol around the city to solve the case, blocking the public in the city bureau.Time is running out, Zhou Xun can only increase the police force, and all employees work overtime to investigate previous case files.That night, three identical cases were discovered across the city, one in Xiangyang District and two in Haigang District.There were four murders in four years, which constituted a serial murder case.After Zhou Xun reported the case, the Municipal Bureau set up a task force, with the Haigang detachment assisting the Changfeng detachment in handling the case.Haigang District sent deputy detachment leader Zhao Xincheng, who had been with Zhou Xun for one term and had similar abilities to Zhou Xun.Zhao Xincheng also brought a consultant, Han Bin, who is the son of the famous criminal profiling expert Han Songge.Han Bin discovered that it took an hour to sort out the corpses in the first case, but it only took twelve minutes this time.

Guan Hongfeng only realized after his reminder that the murderer was indeed not very skilled the first time.The two cooperated very well and listed the characteristics of the murderer one by one: male, 1.8 meters tall, with a self-driving vehicle. On the day of the crime, he most likely used a modified window breaker to open the rear window and use it to kill... The two were extremelyThe tacit analysis impressed Zhou Xun and Zhao Xincheng who were present.The vehicle was discovered on the crime scene surveillance. Zhou Xun and Zhao Xincheng went to see the surveillance. Guan Hongfeng took Han Bin to the forensic room to see the body. However, no major breakthroughs were found.Before leaving, Gao Yanan gave Guan Hongfeng a file bag, which contained Li Di Shen's autopsy summary and a pregnancy test report, which showed that Gao Yanan was pregnant!

When Guan Hongfeng saw it, he immediately tore up the paper and flushed it into the toilet. He had no intention of telling Guan Hongyu about it because now was not the time.There were seventeen cars passing through the intersection at the crime scene, and Zhao Xincheng went to visit them with a checklist.Guan Hongfeng suspected that the murderer probably started tracking Li Dishen at his last destination, the Fire Palace Club, and as long as he found the victim's driving route, the matter would be simple.
