Bai Yaqing waited for the worker named Lao Wang to leave, and then walked over to ask the person just now.

"Eh, hello."

"Who are you?"

"I want to ask, did you just say that Lao Wang built the wall in the middle of the night, is it the project to build a house for a man named Ah Cai?" Bai Yaqing asked.

"yes, why are you asking this?"

"No, I'm just curious......"

"It's a lot of fun."

Bai Yaqing has now confirmed that there must be something wrong with this person building a wall in the middle of the night.

According to the conversation they just had, it should be that when they were resting after work, this worker named Lao Wang built the wall in the middle of the night, so it aroused the curiosity of others.

"Hey! Lao Wang! Bai Yaqing screamed, and when the worker turned his head, she took the opportunity to rip off his hair.

As soon as he turned his head, he saw Bai Yaqing standing behind him.

"Who are you? What's the matter with me? ”

"No, I recognized the wrong person." Bai Yaqing put her hands behind her back and said.

“……”

Bai Yaqing got his hair, just go back and test his DNA.

Because Liu Liqiong was raped and killed, the DNA tissue of the murderer was left in her body, as long as this hair was taken back for examination and compared with the DNA.

………………

Police Identification Bureau.

“Anita。”

"Yo, why is Team Leader Bai so free?"

"That's right, I just got a hair, and I suspect that I am the murderer of this case, so please help me check it."

"Hair? How many? ”

"I don't know, here." Bai Yaqing took out a small transparent bag with a few hairs in it.

"Okay, I'll have someone send it to you when it comes out later."

"Thank you!"

Bai Yaqing returned to the office of the first group of serious cases and waited anxiously.

Seeing that she was slowly approaching the truth and was able to find out the murderer, she was very excited......

[I don't know what to be excited about]

"Xiaoqing, don't worry, the inspection at the forensic department also takes time." Zhang Zijun poured her a glass of water and said.

"Of course I know......" Of course Bai Yaqing knew, but he was in a hurry......

But no matter how anxious Bai Yaqing was, the DNA comparison report was delivered an hour later.

The report clearly states that the two sets of DNA are identical and belong to the same person.

"That's right! Sure enough, the murderer was found! After reading it, Bai Yaqing said excitedly.

"Then let's go!"

Bai Yaqing and Zhang Zijun drove directly to the construction site, but when they arrived, they learned that the worker named Lao Wang was ...... Let's go......

"Are you looking for Lao Wang? He's gone. ”

"What!? Let's go!? Bai Yaqing and Zhang Zijun said in unison.

I was very surprised, I didn't expect to run so fast......

But she didn't reveal her identity today! Who the hell said that......

"Where did he go?"

"He said he was going home, I don't know the specifics."

“……”

Got home...... It must be absconding in fear of crime!!

Bai Yaqing immediately got the personal information of this old Wang from the contractor, and immediately sent out a wanted message.

The first thing is to let Sha Sha check where Lao Wang is now.

About half an hour later......

"Team leader, I checked and took a long-distance bus."

"Shasha, book a ticket now, we're going to City C."

"Okay."

But Bai Yaqing didn't expect that Lao Wang to be so cunning.

Although he said that he was going home by car, he couldn't find anyone in City C......
