When Murong Fei received Si Ling's call, he had already finished dissecting Huang Dagui's body, left the autopsy room, and returned to his own office. Pen, fun, and www.biquge.info

He looked at the time at two o'clock in the morning, thinking that Si Ling's DNA test results were really timely, and he wanted to call her himself, but he was afraid that Si Ling was sleeping in the laboratory, and he felt that it was always bad to disturb her in the middle of the night.

"Murong, I'm sorry to disturb you." Si Ling's voice was not exhausting.

"Si Ling, how can it be? I've just finished dissecting and haven't slept yet. ”

"Well, that's hard."

"The same goes for you."

"Want to hear the results?"

"Of course."

"Everything went as you wanted, and it all turned out better."

"That's great."

"Especially that half of the tooth, after treatment, the effect is quite good, the DNA information is not bad at all, it can be confirmed that it is Pan Qiaoyun's tooth."

"Right? In fact, I was also more worried, only half of the tooth remained, and it passed through the digestive tract of the little Pomeranian, and the tooth found from the dung heap was also examined by you, which is really a great miracle. ”

"What? You say the tooth was found in a dung heap? ”

"yes, the person who sent it for inspection didn't tell you? That's right, the people at the police station don't know either. ”

"My God, you really know how to find a way, even the poop of the puppy, and oh, the blood on the iron cage fence and the dog's hair is Huang Dagui."

"This is also our speculation, we suspect that the Tibetan mastiff bit Huang Dagui to death, there is just a lack of evidence in this regard, you have made up for it for us now, now we can boldly say it."

"Is it a Tibetan mastiff?"

"Yes, it's a big one, it's black, and when I saw it, it had a fierce look in its eyes, and if you saw it, it would be very scared."

"I'm most afraid of dogs, children have been arguing for many years, I want to raise a puppy, but I just can't make up my mind."

"You can raise a teddy dog, it's more docile, it's still good to have a puppy, and children will become more loving."

"When it comes to raising dogs, let me think about it again, the last sample is the wipes in Huang Dagui's nails."

Murong Fei originally didn't have much suspense about this sample, according to his speculation, this should be Pan Qiaoyun's bloodstains, because in his system, it was Huang Dagui who killed Pan Qiaoyun, he said, "Hmm." ”

"This swab detected mixed DNA, which is the mixed DNA of Pan Qiaoyun and Qi Yipei."

After Murong Fei heard this, his heart tightened, and he asked, "It can't be mistaken, right?" ”

"How could it be, the one you sent over was just a swab, I did a pre-experiment, and I determined that it was bloodstains, and then I did the DNA, the whole process is very standardized, and it must not be wrong."

Murong Fei couldn't figure out how Huang Dagui's nails could have Qi Yipei's DNA, and he asked, "Si Ling, so the wipes in this nail, Qi Yipei must have left blood stains?" ”

"That's not necessarily, although there is a bloodstain reaction, I can't tell whose blood it is, maybe it's Pan Qiaoyun's blood, maybe it's Qi Yipei's blood, anyway, as long as one party's blood exists, the experiment will be positive, and the other party may be left with other tissues, of course, it may also be blood."

"For example?"

"It's very simple, for example, Huang Dagui's nails scratched Qi Yipei at the beginning, and it is possible to leave some epithelial cells in Qi Yipei's skin epidermis on the nails, right?"

Murong Fei was reminded by Si Ling, and he suddenly became enlightened, and said, "You say, Qi Yipei may have been arrested by Huang Dagui?" ”

"yes, I'm just giving you an example."

Murong Fei said: "This example is very good, I happened to have something wrong here, the investigation found that Qi Yipei lied, she said that she went back to school from the farm last night, but after verification, it was found that she did not go back to school, and now you have detected her DNA in Huang Dagui's fingernails, I suspect that what happened in the farm yesterday may not be as simple as I originally imagined." ”

"I don't know much about the things on the scene, anyway, that's how I inspected, you can do it yourself."

"Si Ling, thank you, it's not early, go to bed early."

Murong Fei said good night to Si Ling, but his mood could no longer calm down, he was recalling the work of the day, especially about Qi Yipei, it was Qi Yipei who opened the big iron door early in the morning, and she called the police, she didn't go back to school at night, but lied that she was back at school, and now Huang Dagui's nails have her DNA again.

Murong Fei thought that if it was analyzed based on the current situation, Qi Yipei was likely to have physical contact with Huang Dagui, specifically, Huang Dagui might really be like Si Ling said, he grabbed Qi Yipei, so he left Qi Yipei's skin epithelial cells on his nails.

So under what circumstances did Huang Dagui and Qi Yipei have physical contact? Murong Fei secretly thought that it was when there was a tearing and scuffling between them that Qi Yipei finally chose to let the dog bite people?

Murong Fei had such a picture in his mind, Qi Yipei suddenly returned to the farm at night for some reason, at this time she witnessed the process of Huang Dagui's murder and broken corpse, and when she was about to leave, Huang Dagui found her, so the two scuffled, Huang Dagui's nails caught Qi Yipei's skin, and when he was in a hurry, Qi Yipei chose to let the dog bite people, but Huang Dagui was bitten to death by the Tibetan mastiff on the spot, and Qi Yipei finally left the farm again.

Murong Fei sat on the chair, he shook his head, which was still active in the middle of the night, and thought, if this is really the process, then, Qi Yipei may choose to disguise herself the next day, lie that she has no time to commit the crime, and leave herself alone, and she knows that Pan Qiaoyun was not killed by her in the first place, and the police can't hook her up from there, Huang Dagui was bitten to death by a dog, and the police will not contact her at the scene, the only thing she needs to worry about may be her own classmate Qu Wenhan, as long as Qu Wenhan doesn't know about it, Then all this became seamless, and he suddenly thought, could it be that everything Qu Wenhan said was not true? He hid everything for his classmate Qi Yipei?

Murong Fei thought, it seems that Wu Long's sensitivity is not unreasonable, although he suspects whoever he sees, when suspicion meets evidence, then this suspicion becomes a fact.

After sorting out the photos and information on the computer, Murong Fei saw that the time was almost three o'clock, his hands left the mouse and keyboard, rubbed each other, stretched, and tiredness had begun to hit him.

He decided to rest first, and he felt that telling Wu Long these thoughts at this time would not make him sleep at any other practical point than to keep him awake at night.
