Under the Skin 猎罪图鉴 Episode 19

The Criminal Police Team of the City Bureau once received an audio file, which contained a recording of the call between M and Du Cheng before his death. In the recording, Du Cheng threatened to kill M and avenge Lei Yifei. With the help of Tongcheng Company, the surveillance video of the Whig Hotel on the night of the crime was enhanced, and Du Cheng appeared in the video. Lu Haizhou handed over these two pieces of evidence to his superiors, and Director Zhang decided to suspend Du Cheng temporarily.

Du Cheng, who was framed, voluntarily handed over his work certificate. Then Director Zhang announced at the meeting that Lu Haizhou would take over the case. Shen Yi questioned Lu Haizhou’s purpose of coming to Beijiang Branch. Lu Haizhou told the truth and invited Shen Yi to the city bureau. At work, Shen Yi declined Lu Haizhou's invitation.

Shen Yi asked Du Cheng to tell himself in detail the trajectory of his actions on the night of the crime, and then Shen Yi drew the scene of the night of the crime overnight, and told everyone what happened the next day.

On the night of the crime, when Du Cheng came to the Whig Hotel and went up to the fourth floor, he saw M's fall. He looked up and found the murderer on the fifth floor. Du Cheng wanted to intercept the murderer from the fire corridor on the fourth floor. After the two fought, Du Cheng was kicked down the steps. Du Cheng got up and chased after him, and the two fought fiercely on the second floor platform again. At that time, the camera should be able to record the figures of the two, but the video sent to the police station only showed Du Cheng's blurred figure. Tampered. The result of the fight between the two was that Du Cheng was pushed down the stairs by the murderer, and the mirror of Du Cheng's watch was damaged in the process. Du Cheng fell into a coma after landing, but when he woke up, he found that the murderer was the same person as the photo M gave him--the murderer of Lei Yifei--Zhou Jun.

Shen Yi's analysis made everyone very convinced. Everyone didn't believe that Du Cheng would kill M, so Lu Haizhou had to send Jiang Feng to lead someone to control Zhou Jun first.

Lu Haizhou interrogated Du Cheng, and Du Cheng told Lu Haizhou a story against the guest. The man behind the scenes set up a human trafficking organization, but unexpectedly, the police officer Lei Yifei caught the evidence, which forced the man behind the scenes to disband the organization. However, M, the key figure in the organization, betrayed at this time and took away important documents. After finding M, the man behind the scenes found that M was in contact with the police Du Cheng. In order to avoid future troubles, the man behind the scenes sent Zhou Jun to kill M and put the blame on the police Du Cheng.

Lu Haizhou understood what Du Cheng meant, and then received news of Zhou Jun's death, and Zhou Jun destroyed the important documents obtained from M before his death. He Rongyue checked and found that Zhou Jun's death was caused by light source-induced epilepsy. Shen Yi checked the files recovered by Li Han from Zhou Jun's computer and found a virus file that could make the screen emit a specific flash.

According to M's description of Du Cheng, although she has not seen the leader of the human trafficking organization, she has heard this voice, and this voice recently appeared when Chen Zhou, the CEO of Tongcheng Company, gave a speech. Zhou Jun's computer once kept photos of human trafficking, and his computer was also installed with the Silver Eagle security system. Whig's surveillance is supported by Tongcheng Company, so only Tongcheng Company can tamper with the video, so Chen Zhou of Tongcheng Company enters the police's sight. Because there was no search warrant, everyone didn't know how to enter the Tongcheng for investigation. Shen Yi proposed to force Chen Zhou to reveal himself.

Du Qing brought Shen Yi to Tongcheng Company in the name of discussing cooperation. While Chen Zhou, the boss of Tongcheng, was away, the two carefully learned about the network security system of Tongcheng Company. Shen Yi focused his attention on Chen Zhou's office. Shen Yi carefully observed the fingerprint lock at Chen Zhou's office door. At this moment, Chen Zhou suddenly appeared. Fortunately, Du Qing came forward in time to help Shen Yi.

Chen Zhou invited Du Qing and Shen Yi into the office to chat, and Shen Yi took the opportunity to extract Chen Zhou's fingerprints from the chess pieces. Chen Zhou offered to learn chess skills with Shen Yi, and Du Qing left first. Chen Zhou's chess style is very aggressive, while Shen Yi is playing chess, he will tell Chen Zhou about the human trafficking case and the murder case of Lei Yifei and M. Shen Yi's move is to stimulate Chen Zhou to act, In this way, they can find Chen Zhou's weakness.
