Back to the criminal police team, He Mingyuan took Qin Daming and his team straight to the Xilai Hotel in K County.

"Lock off the scene immediately! No one who has anything to do with it is not allowed to enter! The car had not yet stopped, and He Mingyuan quickly made a deployment.

An hour later, Qin Daming reported to He Mingyuan, "Captain, according to the forensic examination, Yan Mingshan died of drowning, and the time of death was around zero morning. ”

"What does the hotel say?"

The hotel owner and waiter said that Yan Mingshan was their regular visitor, and there was a beautiful girl named Liu Qing by his side recently, either eating or dancing, and the relationship was very close. This time, Yan Mingshan came with this girl, and the time was about ten o'clock in the evening. ”

"Liu Qing? Beautiful girl? Eleven o'clock in the evening? He Mingyuan faintly felt that this was another strange case, and it was another hard bone that was difficult to gnaw.

"Are they eating or dancing this time?"

"Eat, among thousands of purples and reds."

"Is there any surveillance video?"

"Yes."

"Put it all over again."

"Yes!"

Sun Lili replayed the surveillance video in the room.

"Didn't you mean two people? Who is that bearded man? He Mingyuan asked while watching.

Qian Gang said, "According to the hotel owner and waiter, the bearded man is a foreign businessman, surnamed Kong, called Kong Liang." He came to the hotel at ten o'clock in the evening and asked for a big set, saying that there would be guests to come later. The waiter arranged Kong Liang to the Thousand Purple Thousand Red Room. At eleven o'clock, Yan Mingshan and Liu Qing came to eat, Liu Qing also wanted a thousand purples, the waiter said that there were already people there, but Liu Qing refused, he had to ask for that room, and pulled Yan Mingshan into it. The waiter was worried that they would fight, so he followed behind and prepared to persuade them, but who knew that not only did the three not fight, but they were very hot, as if they were friends who had not seen each other for many years. They pushed the cup and changed the lamp, drank a lot of wine, and in the end, Yan Mingshan got drunk, and Kong Liang helped him to the room. ”

After He Mingyuan heard this, he felt that things were getting more and more weird, and got up and said, "Let's go to the room and have a look." ”

Qin Daming, Qian Gang and Sun Lili accompanied He Mingyuan upstairs and entered the room of 808 Kong Liang first. Qin Daming said, "This Kong Liang is the most suspicious, if Yan Mingshan did not die normally, Kong Liang would be the murderer." ”

"Why?"

"Kong Liang's ID card, home address, and work unit are all fake, and his face is probably also fake, especially the long beard on his chin, which is very eye-catching, and must have been glued on. In addition, he left the hotel before dawn and his current whereabouts are unknown. ”

Room 808 was very clean, not a single hair was left, let alone other clues to the crime. In fact, He Mingyuan didn't expect anything to gain, but by the way, what he paid the most attention to was Yan Mingshan's room, and I believe that there would be clues there.

After entering room 809, He Mingyuan really found a few suspicious places. The first thing that catches your eye is Yan Mingshan's costumes, which are scattered in one place. Under normal circumstances, when a person is drunk, he should fall asleep when he returns to the room, even if there is help from outsiders, it is to help him take off his shoes and socks to cover the quilt, and still run directly to the bathroom without taking off the toilet. Looking at the bathroom again, more than ten hours have passed since Yan Mingshan entered, and the water traces on the ground are still clearly visible; Yan Mingshan's body had no external injuries, it was indeed drowned, if it wasn't killed by him, there was only one possibility, that is, cardiac arrest while bathing or a sudden loss of consciousness in the brain. Yan Mingshan is over fifty years old, and he spends money like running water, either soaking on the wine table or soaking in the women's pile, he has already been hollowed out, and it is reasonable for him to die accidentally. However, under normal circumstances, sudden death caused by cardiovascular and cerebrovascular diseases should be quietly died, without struggle or choking; Judging from Yan Mingshan's corpse, there was a struggle, and there was choking, which was very suspicious.

After on-site investigation and autopsy, Yan Mingshan did not die of cardiovascular and cerebrovascular diseases. His lips were blue and there was a large amount of fluid in his lungs, and he probably died of suffocation under the action of external forces. Judging from the clues that have been obtained, the murderer is either Kong Liang or Liu Qing, or Kong Liang and Liu Qing collaborated to commit the crime. In addition, there is also a possibility that the murderer lurked in the guest room in advance, and after Kong Liang left, he dragged Yan Mingshan to the bathtub and choked to death. Although there are many possibilities for the murderer, the most suspicious is naturally Kong Liang.

Judging from the surveillance video, Kong Liang is sturdy and agile, and he helped Yan Mingshan into room 809, and he has the best chance to commit a crime. If Kong Liang makes a move, Yan Mingshan will definitely die. Judging from the causes and consequences of the incident, Kong Liang also has the most doubts. He came to the hotel alone for dinner and asked for a big set, saying that there were still guests coming, but the guests did not show up from beginning to end. When Liu Qing dragged Yan Mingshan into Kong Liang's private room, Kong Liang not only did not object, but agreed to share a table with them, which seemed to make no sense. They ate and drank until midnight, although Kong Liang was not drunk, he was not much better than Yan Mingshan, if it wasn't for the ghost in his heart, he should have slept until most of the night after returning to the room, and he would never go quietly before dawn. In the end, all his documents were forged, which created many obstacles for the police to detect, indicating that he was a veteran and had strong anti-reconnaissance capabilities.

In addition to Kong Liang, Liu Qing also has a lot of suspicions. First of all, Liu Qing's appearance was a bit abrupt. Liu Qing, a native of Heilongjiang, came to K County two months ago and worked as a waiter in the dance hall of the Xilai Hotel. Since climbing the big tree of Yan Mingshan, Liu Qing has given up his work in the song and dance hall, and has circled around Yan Mingshan in front of and behind him. In the eyes of outsiders, Liu Qing is Yan Mingshan's little lover, who spends a lot of money and is glamorous. That night, Liu Qing followed Yan Mingshan to the Xilai Hotel and asked for a red private room by name; The waiter told her that there were already guests there, but she was arrogant and pulled Yan Mingshan to break in. A weak woman, relying on Yan Mingshan's money, in front of the hotel owner and waiter, she was coquettish and unrestrained, and she would never be uncomfortable with strangers. Yan Mingshan is rich, but his body is thin, and once he starts to move, he will definitely be beaten and lose his armor. Liu Qing goes in and out of Fengyue Field, is well-informed, and will not do stupid things that humiliate himself. There is only one explanation for Liu Qing's fearlessness, that is, she knew in advance who the guests in the red envelope room were, and reached some tacit understanding with that person. What Liu Qing has to do may be to bring Yan Mingshan there and then get him drunk. In terms of room arrangement, Liu Qing also used a lot of brains. The waiter originally arranged for Liu Qing and Yan Mingshan to live in the same room, but Liu Qing did not agree and wanted to live alone. Of course, this makes sense, because any girl will take care of her face in public, and Liu Qing's expenses are all borne by Yan Mingshan, so there is no need to consider the issue of saving or not. The waiter arranged for Liu Qing to live in Yan Mingshan's opposite for the second time, so that they could take care of each other, but Liu Qing still disagreed and asked for an upstairs room, the reason was "stay away from those two stinky men", which was obviously a strong word. This shows that she knew in advance that something would happen in room 809, and the farther away she was, the easier it was to get rid of the relationship. If these inferences are true, then Liu Qing must be Kong Liang's partner, and he is the accomplice and promoter of the murder of Yan Mingshan.

"Smack!" He Mingyuan pondered for a long time, and finally sorted out some clues, and issued an order to the serious crime team, "Call up all the surveillance videos of the Xilai Hotel, and check who Liu Qing has dealings with besides Yan Mingshan." ”

"Understood!" Qin Daming immediately dispatched manpower and acted separately, focusing on restaurants, dance halls, and swimming pools to conduct a comprehensive investigation.

After a busy afternoon, I finally found out Liu Qing's activity trajectory. During this period of time, in addition to frequent visits to the dance hall of the restaurant of the Xilai Hotel with Yan Mingshan, Liu Qing also had dinner with another man, danced and swam and swimming. That man was Leng Qinghe, the deputy mine manager of Dayaogou Coal Mine. After comparing the video screenshots, the bearded Kong Liang's figure is very similar to Leng Qinghe's figure, and it can even be identified as the same person.
