After forensic identification, the murder weapon used by the murderer to stab Wu Kaifei is very similar to the murder weapon in the "9.16 Case" and the "9.29 Case", and the possibility that the same murderer committed the crime cannot be ruled out. In order to get a more definite answer, Zhao Hongshan took Xia Shi to find a small inn opened by Wu Kaifei's fellow student to further verify the identity of the mysterious tenant.

Walking through the dark and narrow stairs to the front desk on the second floor, Zhao Hongshan took out his police ID card and said straight to the point to the proprietress who was playing with her mobile phone to fight the landlord: "Hello, do me a favor, we want to verify the identity information of the guests staying in room 206." ”

"Yo, what's wrong?" The proprietress put down her phone, looked at Zhao Hongshan in surprise and asked, "Is that man a fugitive?" I'll just say, when he moved in, he was secretive, mysterious, and didn't look like a good person. ”

Zhao Hongshan smiled bitterly, and said in his heart, why don't you call the police if you don't look like a good person? Now that something has happened, what's the point of saying these afterwords. "Eh, you show us his registered identity information."

"Okay, you guys wait a minute." The proprietress was very active, quickly flipped through the notebook for recording, pointed to one of the messages and said, "Oh, this is the person you are looking for." ”

Xia Shi took the notebook, looked at the information on it, and muttered: "Sun Ping, check in at 20:18 on October 3, ID number 510781...... Oh, that's not right. He put down the notebook, turned his head to look at Zhao Hongshan and said, "This is not the same person we are looking for." ”

"Maybe it's a fake identity." Zhao Hongshan reminded. Then, he took out a photo and handed it to the proprietress and said, "Take a closer look, is it this man who lives in room 206?" ”

"Hmm...... Like him......" The proprietress frowned, as if she wasn't quite sure of the answer. "As I said, he's been secretive and wears a hat, and I'm not sure he's the one you're looking for."

"Don't you have surveillance here?" Zhao Hongshan pointed to the camera installed in the corner, "Call it up and show us." ”

The proprietress obediently did so and adjusted the surveillance video to the night of October 3, the time when the man checked in. "See for yourselves, this is the one who lives in room 206. Strange to say, this person paid for the house for a total of three days, and originally planned to stay until today. But last night he packed up his things and left, and cleaned the room very clean. ”

"When did he leave?" Xia Shi asked as he checked the surveillance.

"It was past 11 o'clock, at that time, I was sitting here watching a TV series on my mobile phone, and I glanced at him, as if I was carrying a duffel bag. I haven't seen him this morning, and when it was almost noon, he didn't come to check out, and I wanted to ask him if he continued to live, but no one answered after knocking on the door for a long time. I wondered if he hadn't come back since he had left last night, and when I opened the door with the spare key, I found that the room had been cleaned up very clean. ”

Taking advantage of the boss's wife's time to explain the situation, Xia Shi had already taken out a picture from the surveillance video that could barely see the suspect's facial features, and said to Zhao Hongshan with great confidence: "Team Zhao, this person is Dong Wei who escaped from R City a few days ago, I think we should be looking for the right person this time." ”

Zhao Hongshan was overjoyed, and hurriedly asked the proprietress , "After this person left, have you touched the room where he lives?" ”

"I just changed the sheets and duvet covers."

"Have you washed the sheets?"

"Not yet, it's in the utility room inside."

"Okay, then please cooperate. I'm going to call someone from the technical team to come here and do the survey, and you can give us all the bedding that the guest used. In addition, you and your family must be more careful recently, try not to go out too late, once you find that there are suspicious people around you, call the police immediately, do you understand? ”

The proprietress nodded as if she didn't understand, and asked with an uneasy expression, "Captain Zhao, what's going on?" Is the tenant you're looking for really a fugitive? ”

Zhao Hongshan replied solemnly: "You just need to know that he is a very dangerous person, don't inquire about anything else." ”

Through the processing of the technical team, the images in the surveillance video have become much clearer, and it can be determined that the tenant who stayed in room 206 on the night of October 3 is He Yao's neighbor Dong Wei.

Although the police have not yet grasped the evidence of Dong Wei's murder, after he left R City and came to Jinshui County, a violent wounding case soon occurred here, and the victim had close contact with Dong Wei not long before the crime.

The entrance monitoring shows that at 21:41 on the evening of October 5, shortly after Wu Kaifei left the hotel, Dong Wei also left for a short period of time, and did not return until 22:33, and Wu Kaifei was attacked by the murderer during the period when Dong Wei left, and Dong Wei was suspected of committing a major crime.

At 23:38, Dong Wei left the hotel again with the dark blue travel bag he brought with him when he checked in, and has not appeared since.

What people can't figure out is still Dong Wei's motive for committing the crime. Suppose that Dong Wei killed He Yao and Xu Zilin because there were some minor contradictions or conflicts with the victims, but Wu Kaifei's actions were unreasonable and would lead to death. Could it be that just because he was lying at the door and eavesdropping on the movement in the room, he unfortunately became the third victim after He Yao and Xu Zilin?

"Maybe our previous thoughts weren't accurate...... Huo Yan reorganized the case and couldn't wait to say her opinion. The murderer sealed the victim's mouth with a steel nail, not necessarily because the victim said something nasty to him that irritated him. Perhaps, he was just afraid that his secrets would be leaked by his victims, so he had to kill them to save himself. ”

"I see what you mean." Gu Song tacitly followed Huo Yan's words very tacitly, "Dong Wei's true identity is still a mystery, and his reason for concealing his identity may involve a very terrible secret. Wu Kaifei's eavesdropping behavior has seriously violated his privacy in his opinion, so he will take the risk to commit the crime, the purpose is to kill people and kill people. It's just that he didn't expect that Wu Kaifei seemed to be a very good high school student, but in fact he had extraordinary motor nerves, and at the time of the crime, there happened to be police patrolling nearby, and he was interrupted halfway through the case. ”

"Then according to what you say, if the murderer knew that Wu Kaifei was not dead, wouldn't he have to kill him again?" Xia Shi said worriedly.

"I can't rule it out." Huo Yan agreed with Xia Shi's opinion.

"Wait." Zhao Hongshan couldn't keep up with the train of thought of several young people, and asked puzzledly, "Didn't Wu Kaifei hear or see anything, why did the murderer have to put him to death?" ”

"Team Zhao, the problem is that the murderer thinks differently from us." Gu Song explained to Zhao Hongshan, "According to our previous analysis, there must be an abnormality in the murderer's psychological condition, and we speculate that he may be suffering from some kind of paranoid delusion. So, as long as he thinks the victim is a threat to him, whether the real situation is or not what he thinks, he must kill the victim, and let the victim die thoroughly, and complete the ritual he thinks is necessary, which is to seal the victim's mouth with four nails. Only in this way did he feel that his situation was absolutely safe. ”

"Isn't this a fucking psychopath?" Zhao Hongshan was very stunned by this, and even more angry.

"You can understand it that way." Huo Yan and Gu Song glanced at each other, and said with a wry smile, "The murderer's crimes are becoming more and more frequent, and his behavior is becoming more and more impulsive, I am worried that it will be difficult for him to control himself now, and it will not be long before he kills again." ”

"Do you want to release the news and use Wu Kaifei to lure the murderer to the bait?" Xia Shi suggested.

"Is that okay? The victim was a child. Zhao Hongshan expressed concern about this proposal, "Moreover, the murderer should be a very cunning guy, I don't think he will be easily fooled by us." ”

Huo Yan said: "Whether he will be fooled or not depends on how 'sick' he is." I believe that for a paranoid person who will not give up until he has achieved his goal, the feeling of allowing a person who is a threat to him to continue to live in the world is like a sharp fishbone stuck in his throat, which will make him sleep and suffer. Once he knew that Wu Kaifei was not dead, in order to protect himself, it was very likely that he would do it again. ”

"Even so, he wouldn't be stupid enough to go to the hospital and kill people, right?"

"It's really hard to say, the murderer's psychology is pathological and distorted, and his behavior is far beyond the understanding of normal people." Huo Yan said, "Or let's take a gamble and let the media release the latest information about the victims, lay traps inside and outside the ward, and wait for the prey to fall into the net." ”

"I think so." Xia Shi was the first to agree, "Anyway, our bait must be transferred, Wu Kaifei will not take any risks, even if he fails, there is no loss." Either way, we have to catch the killer as soon as possible, and we can't let him hurt more people. After Xia Shi finished speaking, he looked at Zhao Hongshan with expectant eyes, although his position was higher than Zhao Hongshan, but this was not his territory after all, and he had to respect the other party's opinion.

Zhao Hongshan thought seriously for a moment and said, "Okay, then do as you say." If the entrapment fails, we'll think of something else. Anyway, Jinshui County is such a big place, I don't believe he can fly with wings. I'll go back and choose a young man with athletic skills to use as bait. ”

"Team Zhao, who are you going to choose when you go back?" Xia Shi raised his eyebrows at Gu Song as he spoke, "Don't we have a ready-made candidate here?" ”
