After committing a thousand perfect crimes, he joined criminal investigation

Chapter 46 DNA comparison results (please read it)

Based on experience, Gao Yi initially judged that the white spots were probably sperm spots.

But whether it is true or not remains to be determined after testing.

Ever since, Gao Yi quickly collected samples and then left 302.

Twenty minutes later, Gao Yi brought the samples to forensic doctor Chen Huimin~
  "Sister Chen, please do a DNA comparison on these."

Gao Yi handed over the collected hair and suspected sperm spots to Chen Huimin.

"it is good."

Chen Huimin was currently piecing together the body parts. Hearing this, she pointed to the tray beside her: "Just put it on that."

"Put it here, Sister Chen." Gao Yi put the things down as instructed, then came behind Chen Huimin and looked at the mutilated body on the medical bed.

The human skeleton is basically put together, and there are indeed no traces of violent hacking.

The body parts were placed on both sides of the skeleton. They were mostly small square pieces, not all the same size, but very regular.

Like cuts of meat cut by a chef.

"Sister Chen, can you test whether the victim was violated before she was alive?"

After reading it briefly, Gao Yi asked.

"No."

Chen Huimin shook her head: "No trace of semen was detected in the victim's body, but the victim should have had sexual experience before his death."

"Ah."

Gao Yi nodded.

During the day, Diao Aiqing's father, Diao Weiye, came to identify the body. He once said that Diao Aiqing had no love experience in high school.

Diao was under the eyes of his parents at that time, so Diao's father's words should be credible.

Moreover, everyone questioned confirmed that Diao Aiqing is an introverted and conservative girl who rarely interacts with others.

In other words, he probably had a boyfriend in college and had sex with her.

"Could it be that writer?"

Gao Yi murmured in his mouth. Chen Huimin didn't hear it clearly, but seeing Gao Yi's frown, she felt distressed:
  "Having been a forensic doctor for eight years, this is the first time I have seen such a cruel case!"

Saying that, Chen Huimin patted Gao Yi on the shoulder:

“It’s amazing that we can make such great progress so quickly.”

"Ah."

Gao Yi hummed, but did not forget to remind: "I'll trouble Sister Chen about the DNA comparison."

"Okay, I'll give you the results as soon as possible."

Chen Huimin said cheerfully.

Gao Yi thanked him again and then came to the team office.

Just at this time, Sun Youmeng also came back.

"How are you doing there? Do you have any clues?"

The moment he saw Gao Yi, Sun Youmeng immediately asked.

"Not ideal."

Gao Yi shook his head: "The room is very clean, and there are no traces of dismemberment."

After speaking, Gao Yi asked: "Where are you?"

"Quite normal."

Sun Youmeng smacked his lips, came to the chair, sat down, and said again: "He is gentle and well-spoken, and he is also very professional in the rental business."

Having said this, Sun Youmeng looked at Gao Yi: "Is it possible that we are overthinking?"

Is Li Ruizhen really okay?

"Let's wait and see."

Gao Yi didn't have enough evidence at the moment and couldn't make a conclusion.

"It can only be this way."

Sun Youmeng sighed.

Combined with the profile of the murderer in the corpse dismemberment case, she didn't think there was anything wrong with Li Rui.

Moreover, in the communication with the other party just now, I didn't find anything unusual about Li Ruizhen.

Professional and positive throughout.

Thinking of this, Sun Youmeng couldn't help but shook his head and began to focus on Diao Aiqing: "I don't know what's going on with Old Tang~"

Tang Zhengyang didn't go anywhere that day. He stayed in the multimedia room and checked the surveillance video transferred from Huainan University.

It’s not out yet!

Gao Yi shook his head and looked at the information about Li Ruizhen in his hand without saying anything.

Now that the autopsy has been completed, no other findings have been found except to determine the time of death of the victim and the discovery of cat hair in the body.

So if you want to find a breakthrough on the corpse, it seems that you don't have this condition at the moment.

On the other side, the team led by Wu Wenhua was conducting a blanket investigation around Hengqiao Road and the murderer's profile.    This is like looking for a needle in a haystack. Whether the suspect can be found is all a matter of probability.

Therefore, in Gao Yi's view, if you want to find the murderer, you must focus on Diao Aiqing.

The two days between the night of June 6 and the dismemberment of Diao Aiqing on the 26th were the most critical.

Where did Diao Aiqing go when he left school on the night of the 26th?

What has she done in the past two days or so?
  Once these are found out, the murderer will no longer be able to hide.

"I heard that you went to investigate one of Diao Aiqing's fellow villagers. How was it? Are there any results?"

Just as Gao Yi was silent, a voice interrupted his thoughts.

Gao Yi looked up and saw Peng Jun walking over with a smile on his face.

"Team Leader Peng."

Gao Yi said hello, and after finishing his words, Sun Youmeng replied:

"Forget it, that Li Ruizhen has nothing to do with the characteristics of the murderer!"

"fine."

Seeing Sun Youmeng's angry and regretful look, Peng Jun comforted him with a smile, and then handed over a document:
  "This is what happened a few days before Diao Aiqing disappeared. See if you can find anything~"

"it is good!"

Sun Youmeng took the document and handed part of it to Gao Yi.

Next, the two read each other's information, and Gao Yi gradually understood the situation before Diao Aiqing's disappearance——

On the morning of June 6, Diao Aiqing returned to school and had classes as usual.

On June 6, Diao Wei went to class. According to the counselor's inquiry afterwards, Diao said that he went out to play with fellow villagers from home.

But Diao did not say who the fellow was.

However, according to the surveillance obtained by Tang Zhengyang, it was found that Diao was behaving intimately with a man in the playground. When they were spotted again, it was fifteen minutes later downstairs at the computer.

After that, the two disappeared from the surveillance camera.

The information is accompanied by surveillance screenshots from the time.

When Gao Yi saw the screenshot, he discovered that the man next to Diao Aiqing was Li Ruizhen.

[Looks like I have to talk to Li Ruizhen! 】

Gao Yi thought to himself and continued to look down——

On June 6, which was the time of bed check, Diao Aiqing applied to the counselor to move out of the dormitory that day.

Finally, on June 6, Diao Aiqing left school at 26pm and never came back.

"In addition, Team Wu has just received news that their personnel responsible for visiting Daxue Lane found traces of Diao Aiqing in a supermarket around 26pm on the th. He bought ballpoint pens and sanitary napkins."

After Gao Yi and the others finished reading, Peng Jun added the latest news.

“I bought sanitary napkins, but I didn’t go back to the dormitory~”

Gao Yi immediately grasped the key information.

In other words, Diao Aiqing has a place to live outside.

Otherwise, it would be impossible for her to buy sanitary napkins and not go back to the dormitory.

"It seems that where Diao went after ten o'clock is the key to this case."

Sun Youmeng also noticed this and mentioned it immediately.

Peng Jun nodded and said:

"We have applied for another batch of police forces from Team Wei, and we will focus on investigating Diao Aiqing's whereabouts after ten o'clock on the 26th!"

After saying that, he gestured to the two of them: "You digest it first."

"Sister Meng, do you want to print a copy of this information?"

Watching Peng Jun leave, Gao Yi took the information and asked Sun Youmeng.

"Thanks."

Sun Youmeng heard this and thanked him.

Afterwards, the two took the printed information and left the office.

……

After a night of silence, Gao Yi finished breakfast in the cafeteria as usual and brought another portion to Wei Qiang and the others.

However, as soon as Gao Yi walked to the door of the office, Chen Huimin, a forensic doctor, suddenly ran over from the side.

Before Gao Yi could react, a document was thrown into his arms:
  "Sister Chen, what is this?"

Gao Yi looked at Chen Huimin in confusion.

"The DNA you want!" Seeing that Gao Yi didn't react, Chen Huimin rolled her eyes, and the next second she showed a surprised expression:

"Where did you find your kid's sperm spots? How could Diao Aiqing's DNA be detected?"

　Thank you readers for your generous monthly ticket recommendations, and I take a bow!
