Advocate for the deceased

Chapter 636 Discovery in Tears
The next day, Zhou Hai rushed to the center early in the morning, went up to the third floor without stopping, knocked on the door and came to Sister Zeng's office.

Sister Zeng was printing data when she heard the sound of the door opening, so she turned her head to the door.

"Oh, it's early enough, it's just in time, the test of the three tears has come out, I'm doing a comparison!"

Zhou Hai paused, and hurried to Sister Zeng's side.

"Did DNA be extracted from tears?"

Big Sister Zeng gave him a white look, "I keep urging him every day, how can I make such an expression?"

Zhou Hai smiled embarrassingly, "Didn't you try a few times before without any results, why did you get it done this time?"

Sister Zeng sighed and pointed to a piece of floor standing on the table next to her.

"I extracted the floor that Fatty dismantled seven times, but I couldn't find DNA. Later, I had no choice but to chip off the wood surface at those three locations, let alone find any."

"Did the DNA match?"

Sister Zeng nodded, "It's exactly the same as the one on the glove, and I analyzed this sample with the DNA extracted from Wang Chunyan's clothes. Before, I only suspected the possibility of father and son or brothers.

This time I feel suspicious and sure, the two DNAs are not the same person. "

Zhou Hai was a little surprised by Sister Zeng's answer, and hurriedly lowered his head and leaned in front of the analysis report.

"Sure?"

"Well, sure, it's not a feeling, but the result obtained from the analysis of the gene chain. With age, DNA will age, and the performance of aging lies in the decrease of DNA telomeres.

Although the relationship between telomere reduction has not been used as a standard for forensic judgment, this is all my personal experience and can only be used as a reference.

Analyzing the DNA extracted from Wang Chunyan's clothes and the DNA extracted from the 1.12 case, I think they are similar in age. "

Zhou Hai instantly understood what Sister Zeng meant. In a case almost 20 years apart, the murderer who was originally thought to be the same person had a similar age, which further proved his judgment.

Zhou Hai said excitedly:

"Great. Although the two cases have been merged, I always feel that the murderer is not the same person. It's just that there is no relevant evidence to prove it. Yours is the best proof!"

Sister Zeng patted the report in Zhou Hai's arms, raised her hand and waved it.

"Take your report and leave quickly. I need to sleep for a while. I didn't go back at all last night. Every time you accept a case, it is so difficult. It really damages my brain cells. No, I need to sleep for a while."

"Then Sister Zeng, rest well, I'm leaving first!"

Holding the report in his arms, Zhou Hai quickly went downstairs. As soon as he opened the door of the office, he saw the fat man answering the phone.

"...Okay, I see, my name is Haizi, let's go and have a look now!"

The fat man hung up the phone and looked at Zhou Hai.

"Just now, Team Huang called. They called you but you didn't answer. They have gone through the list of people on the list and found two people who are related to those five people."

Zhou Hai's eyes lit up, "Let's go and have a look!"

After speaking, he turned and walked towards the door. The fat man became anxious when he saw it, grabbed his coat and suitcase, and quickly chased him out.

"Haizi, wait for me~!"

Four or ten minutes later, the two came to the DC District Detachment. As soon as they went upstairs, they saw Da Zhao standing in the corridor, with his arms folded and a smile on his face. The fat man gave him a white look.

"Okay, stop wandering here, have they started yet?"

Da Zhao bared his teeth and pushed open a door, "I'll be waiting for you!"

Zhou Hai walked in quickly, Huang Zhongsheng was sitting in the room, and the big cat was interrogating next door through the glass, and several people walked over quickly.

"What did Team Yellow find?"

Team Huang had a smile on his face, and handed Zhou Hai the list that Zhou Hai had crossed yesterday.

"There are some gains. Two of these people are really connected. The person in the room next door is Jiang Jianguo. He is the eldest son of Jiang Junxing. He used to work in Haier, and later he applied for Mitsubishi after-sales service. He has been working here for three years now. .

There is also Chen Xingyu, the second child of Chen Yushan's family in the lounge. He has a good personal relationship with Jiang Jianguo and has similar work experience. He followed Jiang Jianguo to work at Mitsubishi.

The interrogation has just started, and no problems have been found on January 1th.

However, according to the two of them, Mitsubishi's management is very strict, and their work clothes are damaged and need to be turned in before they can receive new clothes. "

Zhou Hai turned around and glanced at the fat man, "You go and take samples from the two people, and then send them for inspection for comparison. The comparison is very fast."

The fat man had no objection, picked up the suitcase and followed Da Zhao, and entered the interrogation room next door for a while. When Jiang Jianguo saw another policeman coming in, he stopped talking and kept staring at the two with a slightly nervous expression.

The big cat raised his hand and knocked on the table, "Jiang Jianguo, don't worry, we're just taking blood for you to compare!"

Jiang Jianguo rolled up his sleeves very cooperatively, and the fat man drew blood skillfully. He took a look at Jiang Jianguo's hands. He was tall and middle-aged, with blackened nails and rough palm lines. He looked like someone who worked all year round. .

On the thumb of his left hand, there is a dirty band-aid wrapped around it, and the edges are a little curled up.

After the fat man drew the blood, he helped Jiang Jianguo pull off his sleeve, and asked inadvertently:
"Why did you hurt your hand?"

Jiang Jianguo snorted, tugged at the skirt of his clothes and pointed.

"Oh, bumps and bumps are common in this job. A few days ago, a piece of skin was scraped off by an iron wire. It wasn't until it touched my body that I realized I was injured."

The fat man found a clean band-aid from the bottom of the exploration box, and smiled at Jiang Jianguo.

"You are already too dirty. If you contaminate the wound, you will get infected. I happen to have a Band-Aid here. Can I change it for you?"

Jiang Jianguo giggled twice, "That's a good relationship!"

Immediately, he raised his hand and tore off the Band-Aid. The upper fingertip of his left thumb lost a piece of flesh, and the wound was very deep.

The fat man knew at a glance that it was not a burn mark, but he hurriedly changed it for Jiang Jianguo, and then followed Da Zhao to another lounge, and returned to the room where Zhou Hai and the others were in after a while.

"The blood has been drawn. Jiang Jianguo has a cut on his hand, but it was indeed a scrape. A long strip of skin is notched. The wound is deep and fresh."

Zhou Hai nodded, he had seen Fatty's movements just now.

"You go and submit it for inspection. Let Sister Zeng compare with the DNA of the 1.12 case and the Wang Chunyan case, and just send the results to me."

Fatty left, and Big Cat's inquiries continued.

"Okay, let's continue with the previous question, how many blue jumpsuits do you have?"

"Two bodies!

The company basically has one person and two suits, and one set cannot be changed and washed. The material is super thick, and we work in sky ladders all day long. If we get dirty, we will be deducted money. "

The big cat nodded and looked at his height. He remembered that Zhou Hai said that the suspect was right-handed and between 180 and 185 in height, but this Jiang Jianguo was of average height and less than 175. He had a big belly and no limbs. How burly he is, it can be seen that there is still a big difference between him and the suspect's figure.

"Is it possible that others can get your work clothes?"
