Rebirth of the open female forensic doctor

Chapter 683 Lost resistance

Although it cannot judge men and women, it is also an important inferential argument.

Even if the shoes are smaller than usual, at least it can be inferred that the murderer is either a woman with larger feet or a man with smaller feet, because it is impossible for a man who wears more than 40 to wear them. It is even more impossible to enter rock climbing shoes of size 36 and 38, and it is even more impossible for women with small sizes.

In addition to these two physical evidences, the technical team also checked other suspicious physical evidences in the bathroom, and found no directional clues to the murderer. On these physical evidences, apart from the fingerprints and DNA of the deceased Li Lanke, there was only another set of fingerprints and DNA.

This set of fingerprints and DNA, which did not belong to the deceased, was identical to the fingerprints and DNA on another set of washing utensils in the bathroom, and belonged to the deceased's secret boyfriend, Dai Lumao.

In the entire apartment, only the fingerprint DNA of the two of them was found. Of course, there were several sets of messy fingerprints at the gate, all of which were left by the property management office breaking in.

The murderer did not leave any evidence in the bathroom during the entire crime process, and even if there was, it was washed away by the current.

Summarizing the current clues, the only directional physical evidence is rock climbing shoes and rock climbing ropes.

"One more thing." Ye Fan tapped his knees with his fingers, and said calmly, "I didn't find anything between my dead man's nails."

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

As a senior forensic doctor, Xia Dong immediately reacted, and said with a palm: "There is a problem, a big problem, no wonder you examined the fingernails and toenails of the deceased so carefully during the autopsy." Having been a forensic doctor for so many years, he actually Made this mistake too.

Precisely because of working as a forensic doctor for many years, autopsy has become an instinctive job, and a fixed inspection process has been formed to determine the time of death, wounds on the body, the cause of death and injury, and the evidence clues left on the body. has been entrenched.

During the autopsy at the scene, no tissue left by the murderer was found under the nails on the deceased's body, so he didn't pay attention any more, but if he was willing to think a little deeper, this was precisely the biggest problem.

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

Even a person who is completely paralyzed, under such brutal and inhumane killing, might still have his potential to explode and struggle a little, but Li Lanke didn't.

"The possible reason for this could 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 it, their eyes lit up, but...

"There was no sign of being tied up on the deceased. I have tested the blood of the deceased, but there is no residual substance such as drug poisoning. What method did the murderer use to make Li Lanke lose his ability to resist?"

As a passionate martial arts fan, Qian Qian's brain twitched, and he made an unreliable guess: "Could it be that he was acupunctured?"

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

But acupressure is not a simple skill, and low-level practitioners can't reach this level. If it is a master, why is it so troublesome to kill an ordinary person?

"Hehe, I was just joking." Qian Qian's brow was sweating as everyone watched.

Although Qian Qian's words were unreliable, there was no bondage or hallucinogenic drugs. How did the murderer make Li Lanke lose his ability to resist?

Also, how on earth did the murderer sneak into the bathroom with the bathroom window closed?This question still confuses Ye Fan.

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

In terms of pharmacology, she has not studied carefully, and she knows very little about this kind of psychedelic drugs, that is, the common sedatives and anesthesia on the market. If the murderer used these, they would have been detected through blood .

He Pingfei is quite clear about the three-educated stuff, he thought for a while, and said: "I haven't heard of this kind of thing so far, it may be a new breed, or it may be something else."

Team Chang marked this time on the whiteboard again, then looked at everyone and asked, "Do you have any other inferences?" He said he was asking everyone, but he looked at Ye Fan.

And the eyes of the others were also looking at her.

Ye Fan smiled wryly and shook his head: "..." Do you think highly of her too much?It made her really stressed, and she couldn't help but rack her brains to deduce new clues.

But handling a case is not based on imagination, and all inferences and suspicions are based on reasonable assumptions based on evidence.

According to the evidence currently in possession of the police, it has basically been said just now, and further inferences can only be drawn after in-depth investigation.

"Okay, since everyone has nothing to say, let's reschedule the next task." Chang Dui clapped his hands, and tapped the names of Dai Lumao and his wife with the black oil-based pen in their hands.

"Pingfei, according to what I just said, you will take a team to Dai's house tomorrow to check the couple thoroughly. In addition, ask from the side whether they are rock climbing enthusiasts and whether they have relevant equipment at home."

After a pause, he moved the oil-based pen to the words Liu, a new type of psychedelic drug, and said, "You have more connections with these things. Let the informant check to see if there are new things on the market, even if they are just experiments. 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."

"Okay." He Pingfei took a notebook and wrote down one by one.

"Han Han, go and investigate the money for rock climbing shoes and climbing ropes, and also, investigate the rock climbing clubs in Lucheng." You take over."

He Pingfei's investigation task is 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 is 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, and all autopsies that should be done have been done. Unless new major problems are found, no more autopsies will be applied.

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

Ye Fan did not leave immediately, but continued to stay in the office, carefully looking at all the materials of the current case, including investigation materials, autopsy reports and technical inspection reports. In the lobby downstairs and in front of Li Lanke's house, the surveillance videos of these places were carefully re-read.
