Although it is not possible to judge men and women, it is also an important inferential argument.

Even if the shoes are smaller than the usual ones, it can at least be inferred that the murderer is either a woman with relatively large feet or a man with a smaller size, because it is impossible for a man wearing a size 40 to wear a size 36 or 38 climbing shoes, and a woman with a size small is even more impossible.

In addition to these two pieces of physical evidence, the technical team also examined other suspicious physical evidence in the bathroom, and there were no pointing clues to the murderer, in addition to finding the fingerprints and DNA of the deceased Li Lanke, there was only another set of fingerprints and DNA.

This set of fingerprints and DNA that did not belong to the deceased are the same as those on another set of washing utensils in the bathroom, and they all belong to the deceased's secret boyfriend, Dai Lumao.

In the whole apartment, only the fingerprint DNA of the two of them was found, and of course, there were several sets of messy finger marks at the door, all of which were left by the property office when they broke into the door.

The murderer did not leave a single piece of evidence in the bathroom during the whole crime, and even if he did, it was washed away by the current.

Summarizing the current clues, the only physical evidence that can be pointed at present is only climbing shoes and climbing ropes.

"One more point. Ye Fan's fingers tapped his knee, and his eyebrows and eyes were calm: "Nothing was found between the fingernails of my deceased. ”

"Didn't find anything, what's the problem?" Qian Qian asked suspiciously, and the others first asked for a moment, showing thoughtful expressions.

As a senior forensic doctor, Xia Dong immediately reacted, stroked his palms and said: "There is a problem, a big problem, no wonder you examined the deceased's fingernails and toenails so carefully during the autopsy." "After so many years of forensic medicine, he actually committed this forensic doctor.

It is precisely because of many years of forensic medicine that the autopsy has become an instinctive work, forming a set of fixed inspection procedures to determine the time of death of the deceased, the wounds on the body, the cause of death and injury, and the evidence clues left on the body, and the thinking has actually been internalized.

At the time of the autopsy at the scene, no tissue left by the murderer was found in the fingernails of the deceased's body, so he did not pay attention to it, but if he was willing to think deeper, this was precisely the biggest problem.

Because the deceased was not fatally killed by a knife, there was no chance of resistance at all, but was tortured and killed alive, in the whole process of torture, she was awake, and there was no trace of being tied up on her body.

Even if it is a person who is paralyzed, under this kind of inhumane torture, maybe he will burst out of his potential and struggle slightly, but Li Lanke does not.

The reason for this possibility can only be that Li Lanke had lost the ability to resist at that time. Xia Dong clapped his hands and said with sparkling eyes.

When the others heard this, their eyes lit up, but they ......

"There are no traces of being tied up on the deceased's body, I have tested the blood of the deceased, and no residual substances such as drugs have been detected, what method did the murderer use to make Li Lanke lose the ability to resist?"

As a hot-blooded martial arts fan, Qian Qian's brain twitched and made an unreliable speculation: "Could it be that he was pointed?"

Hey, a pair of eyes cast a death gaze, even Ye Fan looked at him speechlessly, but it was not impossible, if the murderer was a cultivator......

But the acupuncture point is not a simple kung fu, low-level cultivators can't reach this level, if a master, if you want to kill an ordinary person, why bother?

"Hehe, I'm just joking. Qian Qian was sweating when everyone saw it.

Although Qian Qian's words are unreliable, he is neither tied up nor used with psychedelics, what is the murderer's method to make Li Lanke lose the ability to resist?

Also, how did the murderer sneak into the bathroom with the bathroom window closed? This question still makes Ye Fan puzzled.

As for the reason why the deceased did not resist, Ye Fan thought about it and asked: "Is there a psychedelic drug that paralyzes the nerves after being hit, but it can't be detected from the blood and organs?"

In terms of pharmacology, she has not studied it carefully, and she knows very little about this kind of psychedelic drug, that is, the common tranquilizers on the market, anesthetics, if the murderer used these, it would have been detected through the blood.

He Pingfei knew more about the things of the three religions and nine streams, he thought for a while, and said: "I haven't heard of this kind of thing yet, it may be a new variety, or it may be something else." ”

The Chang team noted this time on the whiteboard again, and then looked at everyone and asked, "Do you have any other inferences?"

And the eyes of others were also looking at her.

Ye Fan smiled bitterly and shook his head: "...... "Don't you think too much of her?" It makes her so stressed that she can't help but want to use her brains to deduce new clues.

However, the case is not a figment of imagination, and all inferences and suspicions are based on reasonable assumptions based on evidence.

According to the evidence currently available to the police, it has basically been said just now, and further inferences will have to be inferred in depth before a new conclusion can be reached.

"Okay, since you don't have anything to say, let's reschedule the next task. Team Chang clapped his hands, and the black oil-based pen in his hand dotted on the names of Dai Lumao and his wife.

"Pingfei, according to what I just said, tomorrow you lead the team to Dai's house, check the couple carefully, and in addition, ask from the side whether they are rock climbing enthusiasts and whether there are relevant equipment at home. ”

After a pause, he moved the oil-based pen to the words of the new psychedelic drug Liu, and said: "You have a better way to check these things, let the informant check whether there is anything new on the market, even if it is just an experimental product, you must find out, if there is not enough manpower, I will apply to the director to see if the anti-narcotics department can send two people to help." ”

"Good. He Pingfei took the notebook and wrote them down one by one.

"Han Han, you go and investigate the money for climbing shoes and climbing ropes, and also, investigate the climbing clubs in Lucheng. The Chang team assigned Han Han again: "Focus on this investigation, and you will take over the investigation of Hong Yi from now on." ”

He Pingfei's investigation task was relatively heavy, so the Chang team handed over Hong Yi's matter to Han Han.

"No problem. Han Han nodded, although He Pingfei was in charge before, it was not a problem for her to take over now.

"Qian Qian, your technical team continues to step up inspections. ”

Next, the forensic team is idle, the autopsy that should be done has already been done, and no autopsy will be applied for unless a new major problem is found.

After the small meeting, everyone received new tasks and left in a hurry.

Ye Fan did not leave immediately, but stayed in the office, carefully looked at all the information of the current case, including the investigation materials, the autopsy report and the technical inspection report, and the two gates of the community that night, the hall downstairs of the apartment where the crime occurred, and the door of Li Lanke's house, the surveillance video of these places were carefully and carefully re-watched.
