After taking it for two days, he didn't come to the door with the police, and Chen Yongxin thought it was fine. But what I never expected was that it was early in the morning. A group of police officers descended from the sky and came to her house and pinned her in her room. Jiang Chonglang investigated Chen Yongxin's colleagues again, and the colleagues could prove that Chen Yongxin had been working with them all afternoon on the day of the crime, so he had no time to commit the crime, and Chen Yongxin's suspicion could therefore be ruled out.

Now the biggest suspect is Qian Xiaotong, because she did not have complete alibi evidence at the time of the crime, but the autopsy report given by Zhang Lanshan pointed out that the fatal injuries caused to Xu Bingyan are not like Qian Xiaotong's causes.

And even now, it is not known who destroyed the hotel's surveillance system at that time. The case has reached an impasse, and the pressure of public opinion from outside is also increasing. Some people have made all kinds of tirades on Xu Bingyan's death on the Internet, and even cult and alien versions have been made up. Jiang Chonglang saw all kinds of so-called "Exploration of the Truth of Xu Bingyan's Death" on the Internet, and he almost wanted to reach out of the computer and sew all the mouths of these people on the other side of the computer.

Now the only way to block the mouth of Youyou on the Internet is to solve the case as soon as possible, and Director Cui also issued an order to solve the case within a time limit. Jiang Chonglang and they were all very anxious and exhausted. Han Yuchao suggested that when there were no clues, it would be better for us to go to the scene of the crime again. Maybe something new will come to discover. Jiang Chonglang nodded, too, go and take a look, maybe there will be new discoveries.

Room 3435 has been sealed for a long time, and people have died, so this place has become a murderous mansion. Not to mention this room, the entire 34th floor, and even the entire Haoxing Hotel's business was seriously damaged. Therefore, the chairman of Haoxing Hotel almost begged Jiang Chonglang and them, "Please solve the case quickly." ”

Entering the room, the scene of the crime is still so messy, and no one has lived in it since Xu Bingyan's death. You can see it. Xu Bingyan had a fierce conflict with others before she died, and after watching the video of the conflict between Qian Xiaotong and Xu Bingyan, it can be judged that in addition to Qian Xiaotong. There should have been other people who had been to the scene of the crime.

Several team members were carpeting over and over again. Suddenly, Han Yuchao pointed to the bottom of the bed and said, "Brother Chong, look." There are blood stains on the carpet of this place. ”

Everyone gathered around to take a look, and sure enough, it was not true. The beds in the hotel rooms have a carpet on each side. Last time, the members of the serious crime team only found that there were more blood stains on the carpet on the side where Xu Bingyan's body was headed, and they did not find that there was also a small amount of blood on the carpet under the bed on the side where Xu Bingyan's corpse's feet were facing. Jiang Chonglang was about to call Zhang Lanshan and ask her to come over for a test, but he didn't expect Zhang Lanshan to dial the phone first, and he spoke in a very excited tone: "Captain Jiang, where are you." I have made a new discovery, Qian Xiaotong should not be a murderer. ”

Zhang Lanshan soon came to the scene of the crime and conducted a hidden blood experiment on the carpet under the bed, and sure enough, there were indeed blood stains on this piece of carpet.

When Jiang Chonglang sent someone to take the carpet for testing, Zhang Lanshan said to Jiang Chonglang and them: "Last time, we didn't watch the video left by Qian Xiaotong, but when I watched it for the second time, I made a new discovery. The last time the video was played, when Qian Xiaotong took the camera out of the air conditioner, and the picture became pitch black, the big guy thought that he had finished watching it, and there were no clues behind. But I pulled the progress bar of the video all the way to the end, and you see. With that, Zhang Lanshan turned on the computer.

The video was put on the last time Xu Bingyan and Qian Xiaotong scolded each other, the two scuffled next to the air conditioner, and Qian Xiaotong faked a fall. I took the opportunity to unplug the camera in the air conditioner, and the picture went black. I can only hear the sound, but I can't see the picture. The last time Jiang Chonglang saw this, Zhang Lanshan dragged the progress bar back with the mouse, and there was a picture on the computer again.

It turned out that after Qian Xiaotong left Xu Bingyan's room, she took out the camera again, only to see her face first, and said with a smug face: "Xu Bingyan, I see how long you can be proud, and it won't be long before you will be ruined." Then, holding the camera again, he shook it twice towards Xu Bingyan's room before leaving.

Jiang Chonglang seemed to see something, and everyone else saw it too. Just when Qian Xiaotong was holding the camera to herself, there was a man faintly tiptoeing forward, and when she turned around and shook the camera towards Xu Bingyan's room, the man was originally walking forward, but when he saw Qian Xiaotong turn around, he quickly turned around and walked backwards. Although I couldn't see the appearance of this man clearly, I could clearly see that he was wearing a black suit, short and fat, and bald head, so he should be a hotel staff member, and he should also be a high-status manager.

Having found a major clue, Jiang Chonglang seemed very excited. As a hotel staff, you have access to the hotel's internal monitoring system, and if you want to turn it off, it's not too much effort. And this person's body characteristics are too obvious, and they can be found as soon as they are checked.

After investigation, the person quickly came into the police's sight. He is the general manager of Haoxing Hotel-Xiao Bing, who manages the floor where Xu Bingyan lives. According to the hotel staff, after the incident, Xiao Bingsheng became ill, so he asked for leave to go home. And at that time, someone also saw that his head was bleeding, and he himself said that it was because he accidentally hit the wall, so he took leave to go home to recuperate, and according to the hotel security guard who was on duty in the CCTV monitoring room that day, on the day of the incident, Xiao Bing once came to the hotel's CCTV monitoring room, and there was something wrong with the interface, so he was sent out.

Jiang Chonglang and his men's search for Xiao Bing was neither too smooth nor too difficult, and according to Xiao Bing's neighbors, Xiao Bing had been away from home for several days. However, now that science and technology are developed, the real-name system for train tickets, and a person's travel record can be found by checking the Internet, Jiang Chonglang quickly discovered Xiao Bing's footprints. A few days later, Xiao Bing was found in another city not far from Yangcheng.

Like Chen Yongxin, Xiao Bing didn't expect the police to fall from the sky so soon and come to his home. The Xiao Bing in front of him is the same as what Jiang Chonglang saw in the video, short and fat, bald, looking at people, especially young beauties, all of them are lustful. The image of a typical lewd middle-aged and elderly nouveau riche.

After searching, the ashtray in Xu Bingyan's room was found in Xiao Bing's residence, Zhang Lanshan did a occult blood analysis of this ashtray with tetramethylbenzidine, and sure enough, it was found that there were blood stains on it, and the blood stains were the same as the DNA composition of the blood stains on Xu Bingyan's carpet, and they all belonged to one person. That's right, it's Xiao Bing's. However, on the top of the ashtray, Xu Bingyan's bloodstain DNA could not be detected.

After the interrogation of Xiao Bing, there was good news and bad news. The good news is that Xiao Bing admitted that he had been to Xu Bingyan's room and witnessed Qian Xiaotong's departure, so that Qian Xiaotong's suspicion could be ruled out; But the bad news is that Xiao Bing never admitted that he killed Xu Bingyan.

Xiao Bing said that he had taken advantage of his position. Often to the beautiful female staff in the hotel, basically the new female staff have been eaten by him, but the big guys dare not speak. On this day, Xu Bingyan stayed at Haoxing Hotel, this was the first time Xiao Bing had seen a female star with his own eyes, so he had the idea of wanting to kiss Fangze.

On the day of the incident, Xiao Bing, who couldn't hold back his lust, first came to the CCTV monitoring room and opened the security guards inside. Then he secretly turned off the hotel's surveillance. To be honest, Xiao Bing himself was a little worried about this hunt, so he drank a few glasses of wine to strengthen his courage. At this time, it was about two o'clock in the afternoon, and at this time, Xu Bingyan and Qian Ruifeng were in the room full of passion, and they were happy. Qian Xiaotong on the other side recorded all this truthfully through a miniature camera. Of course, none of this is known to these people.

At about 2:50, Qian Ruifeng finally left Xu Bingyan's room. Xiao Bing, who had been waiting for a long time, finally had the opportunity to go in and have a look, but at this time, the chairman of the hotel asked him to go to the office. When he came out of the chairman's office and went to the 34th floor, when he wanted to go to Xu Bingyan's room, he suddenly saw Qian Xiaotong come to Xu Bingyan's room, and heard the sound of two people scuffling together. He wanted to rush in and have a look, but he gave up because he was too cautious.

Xiao Bing tiptoed outside for about ten minutes, and finally saw Qian Xiaotong leave Xu Bingyan's room. He took a few breaths, and when he was about to go in to have a look, he saw Qian Xiaotong turn his head and face Xu Bingyan's room with something, so frightened that he quickly turned around and walked back.

After Xiao Bing officially confirmed that Qian Xiaotong had completely left the floor, he mustered up the courage to knock on Xu Bingyan's door. Xu Bingyan asked him who he was, he said that he was a hotel waiter, Xu Bingyan's assistant had something to give him, and Xu Bingyan opened the door unguarded. After entering the door, Xiao Bing said that he was the general manager of this hotel, and he was also a super fan of Xu Bingyan, and he had always admired Xu Bingyan in his heart, and he had always wanted to have close contact with Xu Bingyan.

Xiao Bing's move made Xu Bingyan angry, and she had just quarreled with Qian Xiaotong and was angry. While scolding Xiao Bing for "hooligans, perverts, and toads who want to eat swan meat", he picked up the ashtray on the bedside table and smashed Xiao Bing's head with a bang, smashing Xiao Bing's head to blood. This also woke up Xiao Bing's smashed wine, and the lust and gall naturally withered.
