Xie Jingchen picked up the phone, and as soon as he picked it up, Cao Tingyang's voice came from inside.

The voice is loud, but also a little excited and impatient.

"Old thank you! You're right! Lin Ruirui and Pei Chengjing do have a relationship! ”

When Xie Jingchen heard this, he handed over the verification work to the other police officers, walked to the corner of the side, and contacted Cao Tingyang in a quieter place.

"How?"

Cao Tingyang held several appraisal records in his hands, and while watching, he was selling with Xie Jingchen.

"You guessed very right last time, you said let me check if Professor Pei is Lin Ruirui's anonymous sponsor, I went to check, yo, it's true.

Not only that, Professor Pei is indeed a good person, he has been helping children in poor areas or children who have lost their parents to study, and he has anonymously sponsored thousands of children.

In addition to that, I found other things, do you want to guess what I found? ”

Xie Jingchen secretly said "sure enough", and then guessed according to Cao Tingyang's words, guessing whether it was unreliable, even if it was a joke with Cao Tingyang.

"How can I guess what you found? It can't be that Professor Pei is Lin Ruirui's father, right? ”

Xie Jingchen remembered that although Lin Ruirui's parents died early, she did have registered biological parents.

When Xie Jingchen said this guess, he laughed, who knew that Cao Tingyang over there suddenly "slumped", and then sighed extremely incrediblely: "Isn't it?!" Can you guess that?! ”

This time, Xie Jingchen felt incredible.

No way?! Professor Pei is really Lin Ruirui's father?!

Cao Tingyang looked at the words on the appraisal report in his hand, muttered, "The blind cat meets the dead mouse", and then read the words on the report to Xie Jingchen.

"In the blood relationship identification report, the DNA similarity between the appraiser Pei Chengjing and Lin Ruirui is higher than 99%.

This certificate of kinship was issued by the affiliated appraisal agency of the Pharmaceutical University of K, and the file records were kept there.

We also found that in addition to anonymous funding, Professor Pei Chengjing would send 30,000 yuan into Lin Ruirui's account every month three months after her freshman year. ”

If An Ruqiao heard Cao Tingyang's words, she would have corresponded to the time when Professor Pei Chengjing gave Lin Ruirui money to the time of "setting up a project team" in Zhou Yang's story.

At this time, Xie Jingchen and Cao Tingyang both had a guess that Professor Pei Chengjing should have suspected that she was his daughter after Lin Ruirui went to college and met, and the facts were confirmed by DNA identification, so he began to give her money.

The problem is that when the K City police investigated Professor Pei Chengjing's family situation, they did not find any emotional problems with Professor Pei, nor did they find that Professor Pei had a second marriage, but such an illegitimate daughter came out.

And the two of them died together.

The father and the illegitimate daughter who had been exiled died one after the other. No, maybe he died in about time.

Xie Jingchen unconsciously moved the suspicion closer to Professor Pei's family. Especially his wife who has been married for many years and has no children, Feng Guanghua.

The possibility of love murder was exponentially magnified after Cao Tingyang saw this blood relationship identification report.

"Are you going to conduct a joint investigation with K City?" Xie Jingchen asked Cao Tingyang.

"That's for sure. Moreover, no clues have been found on the K side of the city, and this report on my side is heavyweight, and we will definitely be the main ones in the joint handling of the case at that time. Haha, I've been suppressed by K City for so long, and I finally turned over. ”

There are important clues in the case, and Cao Tingyang, who has been investigating the case for a long time and is about to be depressed, finally has a smile after handling the case for several days.

It is always a pleasant thing to be able to clear the innocence of the deceased.

Fang Ling, Li/Peng, and An Ruqiao all made notes, but none of them left until the evening, and did not follow the police back to the police station until the evening.

Both Li/Peng and Fang Ling will be investigated as suspects and will be temporarily detained in a police station for one day.

An Ruqiao is purely self-motivated and doesn't want to go. Zhou Yang was just about to give her a clue before he died, but as soon as he said the beginning, the person died, making her uncomfortable.

This kind of talk is half-talked, and it's too annoying. However, Zhou Yang didn't mean it, but the person died, and there was no way, so An Ruqiao couldn't take this anger out on his head, so he secretly recorded the account on the murderer.

In addition, some clues and speculations from Zhou Yang's story, she wanted to keep exchanging information with Xie Jingchen.

After a half-day search at the scene, the police recorded two important suspicions.

First, there is the question of where the murderer will go after killing people.

After searching the scene, the police walked several times along the color steel plate separation wall, and found no tools that could be used to climb the wall with the help of the wall, either inside or outside the wall. So, in the afternoon, this lakeside park resort, which was closely guarded and did not see any suspicious people entering or leaving, was like a large secret room.

Second, there is the question of how the murderer went downstairs after he fell from the upper floor and killed people by falling from a steel bar.

The murderer's footprints are only those who go upstairs, and there are no those who go downstairs, unless the murderer walks backwards when he goes downstairs, and according to the route of going upstairs, every step coincides with the footprints when going upstairs.

But it's too slow to walk like that, and I'm sure I'll meet An Ruqiao who went upstairs to check.

Regarding this suspicion, Xie Jingchen faintly guessed, and felt that the murderer should have used scaffolding to quickly go downstairs, but it has not yet been verified.

At night, it is inconvenient to handle the case, and the police also need a certain amount of rest, so most of the police go back to rest, leaving some to guard the crime scene.

Before leaving, the police also installed monitoring instruments that can be taken at night every 10 meters around the color steel plate separation wall to prevent suspicious people from entering and leaving.

There is no way, the area is too large, and it is not realistic to rely on manpower to guard it.

An Ruqiao waited until it was dark, that is, around six o'clock, when the police officers took Fang Ling and Li/Peng back to the police station, and was sent back to the homestay by Wang Zixian.

After returning to the B&B, An Ruqiao sent Wang Zixian away, and then went to the outside of Fang Ling's beauty shop to find the mobile phone she threw down.

With her eyesight and memory, she can remember the exact location of the phone after it was dropped, and it was easy to touch it in the dark, but it turned out to be empty.

Tsk, lost my phone.

At that time, he dropped his mobile phone, mainly because he didn't want Xie Jingchen to use his mobile phone to locate or monitor.

The man was able to install surveillance in her house, and An Ruqiao wasn't sure if he would do it again. After all, when she took a shower last night, her phone was left in the living room outside.

Although she wants to cooperate, she still wants to keep some hole cards.

It's a pity, she originally wanted to send a message to Xie Jingchen and invite him to "spend a good night together".
