Hearing the answer, the Chang team was slightly disappointed.

"We didn't consider Dai Yubin before, but now that it has been confirmed that he did not go to sea on December 31, will Li Lanke's death be related to him?"

"When you say this, it is indeed full of suspicions, if Dai Yubin is not the murderer of Li Lanke, could it be that we have investigated the wrong direction from beginning to end in this case?"

Dai Yubin obviously does not meet this point.

However, these doubts are still very reasonable, and they are really unreasonable, especially as a normal man, he can better understand that when they analyzed this point before, the psychological profile of the murderer was inclined to a woman, or an abnormal man with a disease.

"Ahem. Team Chang coughed lightly, although he was discussing the case, but the words were still a little awkward in his ears.

Even if Dai Yubin really hated Li Lanke as much as Liang Yunyue because she was a junior, and hated her so much that he slashed her with a hundred and eight knives, but this didn't prevent him from reacting to the fruit of a mature woman, right?

Although Li Lanke is older than Dai Yubin, he is only in his twenties, and it is the time when he is mature and charming, otherwise it would not have been possible to attract Dai Lumao and hang him for so long.

"In addition, from Dai Yubin's rape and murder of Dong Yatong, it can be seen that he is a normal man, or a man who is full of lust, such a young man with strong blood, in the face of Li Lanke's fruit, he actually used 'props'?"

It's not because of the experience of killing people, so the second time is calm, right? It's only two or three hours apart.

Li Lanke's corpse, as well as the scene environment, all told her that the murderer of her was delicate and had a very strong psychological quality, but in Dong Yatong's image memory, Dai Yubin obviously did not have such mental quality.

Another point, in the image memory that Dong Yatong passed on to her, she clearly saw that Dai Yubin was very frightened and flustered after killing people, and obviously did not have the psychological construction of premeditated murder.

Team Chang obviously didn't understand what Ye Fan meant, she shook her head and explained: "I mean, if it's really as you deduced, why is he in such a hurry, even if he has planned to kill Li Lanke, why does ......he have to rush at that point in time? It's like a rush. ”

Judging from the location and time of the two killed, after killing Dong Yatong and then killing Li Lanke, although the time is compact, it is not impossible to complete, in this time period, Dai Yubin can completely go from Jingtai Mountain to his home, and then to Li Lanke's apartment.

"Indeed, but from Dong Yatong's 'confession', it is obvious that her killing was Dai Yubin's temporary uprising, not a premeditated killing, it was an accident, so she was not in the plan. "The team didn't hear anything wrong for a while.

"Judging from the map route, from Jingtai Mountain to the villa area in the city center, the fastest time is also one and a half hours, plus it was at the peak of traffic flow at that time, how could it take nearly two hours, and then from the villa area to Li Lanke's apartment community, and then sneak into the community to kill, this time is too tight. ”

According to Dong Yatong...... said, she was killed at about seven o'clock in the evening on December 31, two or three hours different from Li Lanke's death time, Dai Yubin killed her and put her in the trunk and transported it home......" Ye Fan said, took out his mobile phone to open the map APP, and entered the distance between Jingtai Mountain and the villa area where Dai's family is located.

Ye Fan inferred according to what the Chang team said, and this possibility could not be ruled out, and some problems that could not be figured out before could be explained, but there were still a few problems that did not make sense.

After killing someone, he rushed to the dock and went to sea with the team, so that the people who really knew the time when they went to sea followed him on the sea, and when the police investigated, he naturally had alibi evidence, and Liang Yunyue did not have the conditions to kill in person due to physical factors, so he could eliminate suspicion, so they completely removed their mother and son. ”

"Could it be, his original plan was to deliberately say that he would go to sea in the afternoon, and the rest of the club thought that he had already gone to sea with the players in the afternoon, but in fact, he asked the players to wait for him at the dock, and he cooperated with Liang Yunyue to torture and kill Li Lanke. ”

The more the Chang team thought about it, the more he felt that it was possible, sat up straight, and speculated: "When we investigated, the confession of the person in charge of the BGR climbing club mentioned that the members of Dai Yubin's team went to sea on the afternoon of December 31, but in fact, after the noon dinner, the other members went to the dock, but Dai Yubin drove Dong Yatong to the top of Jingtai Mountain, and he did not go to sea in the afternoon as planned. ”

"Will going to sea be a pre-set bureau to eliminate his suspicion?"

Dai Yubin is a champion in a rock climbing competition, climbing those floors is trivial to him, and Li Lanke is the third party of his parents' marriage contract, which makes her mother sad, and he can also hate her to the core, and then maybe he inherited Liang Yunyue's violent factor in his genes, and when he kills people, he carries out inhumane torture and killing.

What if she set up a murder scheme, put mud and sand in the bathroom window on the afternoon of December 28 under the pretext of getting back the recording backup, and then let her son Dai Yubin sneak into the apartment bathroom with a climbing rope and brutally kill people on the night of December 31?

Liang Yunyue loves her children so much, and she has an unusually controllable desire, and Dai Yubin called her as soon as he killed her, instead of Dai Lumao, which shows his dependence on his mother.

But what if she had a helper?

Liang Yunyue overturned the police's accusation of torturing and killing Li Lanke with a fear of heights, and it can be seen from her physical report that with her physical fitness, she really can't do extreme sports like rock climbing.

The Chang team's eyes widened, and after he finished speaking, he shook his head and said: "Impossible, that life-saving knife is consistent with the knife edge on Li Lanke's body, and there are climbing shoes with the Y mark, all kinds of traces point to the Dai family." ”

"There are suspicions, and there are also physical evidence, and now everything will be clear only when Sister Han Han brings Dai Yubin back. Ye Fan can't say for sure now whether Dai Yubin and Li Lanke's death have anything to do with it.
