Murong Fei was in a daze, he thought that if Chen Chen disguised the scene, Chen Chen would most likely go outside and find a random hair, even if the police could detect the DNA of the hair, the police would never be able to find the owner of the hair, thus bringing this case into the abyss and becoming a cold case that could not be solved. Pen, fun, and www.biquge.info

Now that the owner of this hair has appeared in his field of vision in this way, can his previous bold idea be valid?

Murong Fei suddenly thought that there must be a difference between the microscopic shape of the hair that generally falls out naturally and the hair that is grabbed on the head, and his own electron microscope can just come in handy?

Thinking of this, he immediately ran to the DNA laboratory on the third floor, and he called Si Ling on the walkie-talkie.

Si Ling walked out of the laboratory and said with a smile: "Murong, didn't you tell you all the results?" ”

"It was a surprise, but now I have a new idea."

"Tell me about it?"

"That hair wasn't cut, was it?"

"Of course not, I just used a cell trap to capture the cells and make sure they are undamaged."

"That's great, I'm worried you're going to cut your hair off and get your DNA tested."

"Now that we're all advanced, not as rough as you think, do you want hair useful?"

"Yes, it works." Murong Fei hadn't recovered yet, "I also need this hair for an experiment." ”

"Then return it to its rightful owner."

"I'm going to observe the shape of this hair."

Si Ling went to the laboratory to take out the sample bag containing the hair, returned it to Murong Fei, and said, "Murong, except for the hair follicles at the root of the hair last time, nothing else has moved, and it won't affect your observation." ”

Murong Fei squeezed the bag of sample materials, and saw that the hair inside was almost the same length as before, and his heart relaxed for a while: "Sister Si Ling, I am saved now." ”

"Is it that serious?"

"Seriously, just wait and see, I feel like I'm facing a big gamble."

Murong Fei trotted all the way to the electron microscope laboratory on the first floor with the sample bag, and he couldn't wait to take the material from his hair and put it into the electron microscope observation table to observe.

Murong Fei observed that the overall structure of this hair was no different from normal, that is, it did not look like it had been acted upon by an external force at all.

Murong Fei was a little excited in his heart, but he thought about it, it was better to do a small experiment by himself, he reached out and plucked a hair from his head, and then took a small pair of scissors to cut a hair from his head, he thought, if the hair obtained by these two different methods was compared under the electron microscope, the difference in results would be obvious.

After a period of operation, Murong Fei obtained a satisfactory result, the hair he pulled out could be seen in the field of view of the microscope, the epidermal keratinocytes and keratin were obviously deformed, but the one cut by the scissors was exactly the same as the hair just checked, and the hair structure was not damaged at all.

Murong Fei knew it in his heart, he now felt that he was getting more and more confident, and he could prove that this hair had not been pulled hard, that is to say, this hair did not support that it was grabbed from the murderer's head when the murder occurred. If the cells that Si Ling captured from this hair through the cell trap could prove that Chen Chen had touched this hair, then the whole chain of evidence would be logical.

When Murong Fei was meditating, his mobile phone suddenly rang, he looked at the phone, it turned out to be Wu Long, he expected that Wu Long had already learned the news at this time and wanted to discuss with him.

"Murong, are you free? If you have time, come to my Crime Squad and ask some questions. ”

"Where you dare to be, I'll come right away."

Murong Fei went downstairs and was about to get into the car, when Su Yi shouted again: "Murong, Murong, tell you good news." ”

Murong Fei turned around, frowned, and said, "It's a matter of DNA, right?" ”

"Hmm."

"I already know, no, Wulong came to me to discuss."

"It's really a god, so this nameless corpse is the murderer?"

Murong Fei said, "You all think so? ”

"Is there any other possibility?"

"I can't say right now."

Murong Fei climbed into the car, drove the accelerator, and ran towards the serious crime team.

In fact, after Wu Long called Murong Fei, he didn't stop thinking, after Si Ling called him, he was really shocked, he immediately contacted the leader of the second group, and there was more than one data from the second group, and the blood of the deceased sent by the second group for poison testing has been detected with a highly toxic rat poison, so it seems that the cause of death of this nameless corpse can be determined, rat poisoning death.

Wu Long straightened the timeline, the deceased's hair was grabbed by Chenchen's mother, and two days later he was poisoned and died by the canal in the wilderness, isn't this a typical suicide in fear of sin?

The case is almost solved, and the next thing that needs to be determined is the true identity of the deceased, what is the relationship between him and Chenchen's mother? And because of what motive did he kill people? Wu Long felt that these questions were not the key, and he could figure them out sooner or later, thinking of this, he took a long breath and felt that the pressure suddenly weakened.

Wu Long's main purpose in looking for Murong Fei was to make him think more about how to find out the true identity of the nameless corpse more quickly through technology, otherwise the case would still not be closed.

But this is not what Murong Fei thought, Murong Fei just walked into Wu Long's office and said, "But ......"

"But what? As if you're going to oppose me? ”

"Yes, I oppose your existing idea, although the owner of the hair has been found, but I feel that this is not the real murderer, his hair was used by Chen Chen."

"You're still holding on to that little idea? Now that the cause of death of the nameless corpse has been clarified, it was rat poisoning, isn't this an obvious suicide of fear of sin? ”

"I've heard about this on the road, but poisoning doesn't mean that you take poison, it may also be poisoning."

"So your little idea has expanded."

"I can say that, because I think my previous judgment was wrong, and now it seems that the hair on Chenchen's stepmother's nails was artificially placed, and it was not dragged down by Chenchen's stepmother."

"Oh?"

"I've observed it with an electron microscope, and it can fully explain this, don't believe it."

Murong Fei took out a few photos he had just printed and showed them to Wu Long with his finger: "Look here, this structure is completely different. ”

Wu Long frowned and looked at the photo and said, "It seems to have that meaning, but I can't be sure, can you be sure?" ”

"Yes, I can be sure that this hair has not been forced, and it should have fallen out naturally, so I now suspect that Chen Chen did it on purpose."

"Even if it's what you say, it can't be related to Chenchen."

"The work is already being done, just waiting for the results of Si Ling, she has obtained an epithelial cell adhered to this hair, if it can be proved to be Chen Chen's cell, then I think this scene is already perfect, whether Chen Chen wants to admit it or not, it depends on your level of investigation."

"Don't worry, if you really give me these results, then I can't let Chen Chen speak, and you underestimate me too much."
