The on-site collection work was done very meticulously.

The first is the body fluids lying on the ground. After testing, it can be determined that there is only one person's DNA information, which belongs to Zhao Guangming.

Sweat was extracted from the metal ring of the gantry, and skin flakes were extracted from the red rope.

The DNA information on the metal ring and the rope were the same and belonged to a woman.

The DNA information of some saliva components extracted from Zhao Guangming's chest is the same as the DNA information extracted from the metal ring of the gantry.

And the pair of Balenciaga stockings that cost Zhao Guangming his life.

On-site investigators found skin flakes on the stockings.

The DNA information obtained is the same as the DNA information on Zhao Guangming's chest.

It can be determined that the stockings hanging from Zhao Guangming's neck belong to the woman on the gantry.

At the same time, detectives extracted mixed DNA material from Zhao Guangming's lower body.

One of them belongs to Zhao Guangming, and the other is consistent with the DNA information on the gantry.

Through the extraction of DNA information from these parts, it can be determined that Zhao Guangming should have been exercising before his death.

Moreover, when Zhao Ming died, some parts of his body were congested and swollen.

Although the eyes were bulging on his face, there was a strange smile of satisfaction on the corner of his mouth.

Judging from these circumstances, Zhao Guangming should have used too much force at the moment of venting, causing the limp stool legs that had been touched by his hands and feet to break.

Then the stockings tightened around her neck and she suffocated to death.

As for the third piece of DNA information, it was found on white cartoon underwear.

This is very strange.

The white cartoon underwear found at the scene was made of pure cotton and the pattern on it was a little white rabbit.

Testers found mixed DNA material on it.

One of them belongs to Zhao Guangming.

However, another piece of DNA information was inconsistent with the DNA information previously detected on the gantry hoops, ropes, and stockings.

What does this mean?

This shows that the underwear hanging on Zhao Guangming's body does not belong to the woman on the gantry.

This is so weird.

Were there two women at the scene?

But, this isn't right.

If there were two women, why did the other woman leave nothing behind except a piece of underwear?

No fingerprints, no body fluid residue, nothing.

This is unscientific.

"Have you found the owner of these two pieces of DNA information?"

Wu Zhiguo shook his head.

"It is being compared in the DNA information database, but there is no news yet."

"Collect the DNA information of the fitness coach who reported the case, as well as the DNA information of Zhao Guangming's wife."

“Then compare!”

"yes!"

…

After leaving the conference room, Chen Yan came to the monitoring room.

In interrogation room No. 1, Zhao Guangming's wife is being questioned.

"Ms. Tian, ​​did you see your husband Zhao Guangming last night?"

In the surveillance footage, there is a woman who looks to be in her thirties.

Women should be very beautiful and elegant, and should be dressed luxuriously and appropriately.

It's just that his expression is a bit serious and his face is not particularly pretty.

The whole person looked a little haggard.

Tian Min, Zhao Guangming’s wife, 43 years old.

Zhao Guangming and Tian Min got married 20 years ago and have a son and a daughter.

"Never seen it."

"Yesterday morning, after Guangming had breakfast at home, he went to work at the company. He called me at noon and told me that he would not come back because he had some entertainment in the evening and would stay at the company."

"Does Zhao Guangming not go home often?"

"No, although Guangming is very busy with his business, he is very caring about his family."

"Except for Mondays and Wednesdays every week, I work out in the gym, and rarely socialize at other times."

"We will all have dinner at home."

"However, because our company is engaged in ocean shipping, and there is a time difference with other countries, Guangming often has to go to the company for video meetings in the middle of the night."

"He is out there...does he have other women?"

"this……"

"Probably not. Guangming is very good to me, and our relationship is very stable. When Guangming holds a video conference at the company, I will personally deliver breakfast to him the next morning."

In the monitoring room, Chen Yan crossed his arms and frowned.

This Tian Min...

Obviously, his understanding of his husband, Zhao Guangming, is not deep enough.

If Tian Min saw Zhao Guangming's death scene, she would definitely not think that Zhao Guangming's relationship with her was stable.

Of course, this does not rule out that Tian Min did not tell the truth.

She knew that Zhao Guangming had been doing mischief outside.

But he kept it secret.

Instead, he did it in secret.

For example, who tampered with the slumped stool legs?

Tian Min has a motive.

Because, the biggest beneficiary of Zhao Guangming's death was Tian Min.

Another interrogation room.

The fitness coach who reported the case is also taking notes.

"Ms. Zhang, do you usually go to the gym so early?"

The fitness coach who discovered Zhao Guangming's body was named Zhang Zimeng.

Zhang Zimeng shook his head.

"I usually go to the gym very early, but not as early as today. I went so early today because I left my phone in the gym."

"Why, you won't doubt that I have anything to do with Boss Zhao's death, right?"

"Of course not, Miss Zhang, don't get me wrong, we are just making inquiries."

Zhang Zimeng’s performance...

Nothing special.

However, as the person who reported the crime, he must be considered within the scope of suspicion.

An hour later.

Wu Zhiguo returned to the monitoring room.

"The DNA comparison results are out."

oh?

Chen Yan took the report and read it carefully.

The two women's DNA information found at the crime scene and the DNA information of the reporter Zhang Zimeng and Zhao Guangming's wife Tian Min were not successfully compared.

From this point of view, we can basically rule out the possibility that Zhang Zimeng and Tian Min were at the scene last night.

Chen Yan shook his head.

As the person who reported the crime, Zhang Zimeng was naturally included in Chen Yan's scope of suspicion.

However, since there has been no successful comparison with the DNA information found at the scene, Zhang Zimeng's suspicion is very low.
To be continued...
