Xiao Qu's shout made Zhou Ning turn around abruptly. If the comparison was unsuccessful, Xiao Qu would definitely not shout like that. It seems that among the known relevant personnel, someone is indeed the murderer.

"Several people?"

"One person, all fingerprints belong to one person. I just asked Sister Cui. In addition to these few fingerprints, she also found more than 20 fingerprints of latex gloves.

I asked Sister Cui if there was anything special about the latex glove marks, such as clubbing fingers. She said that there were a few latex glove fingerprints on the plastic sheet that Yu Guangyao and Zhang Qiujian were laying on. Got it, it's clubbing. "

Da Zhao slapped Xiao Qu on the back, and moved directly to the screen.

"You said you were lonely, and asked whose fingerprints belong to you? Whose?"

Xiao Qu smiled awkwardly, scratched her head and said:
"I forgot excitedly that the fingerprints belonged to Li Hua, and I observed the location of the fingerprint distribution. They were all inside the plastic sheet. We didn't pay attention at that time. The plastic sheet is double-layered and cylindrical. It is a kind of material to buckle the plastic greenhouse."

Zhou Ning was a little surprised by this discovery. He hoped to see physical evidence, but Bai Hua sent him to the city bureau without seeing it at all. Thanks to Sister Cui's ability, she also found the problem, but why did the fingerprints appear in the interlayer?

Liu Yongxin approached, and the expression on Zhou Ning's face obviously didn't understand. He asked Da Zhao to help, picked up a disposable surgical gown, folded it in half, and said to Zhou Ning:

"Look clearly, when cutting and folding this barrel-shaped plastic film, fingers will be inserted into it, and it is unrealistic to twist it with gloves on, just like the action of turning a book, you need to dip some saliva, and then twist it like this , It’s a pity that it’s too old, if the DNA test was done at that time, maybe the murderer’s DNA could be found.”

Zhou Ning suddenly realized that he had figured it out. If he cut the two layers together, it would be easy to delaminate, which would reduce the toughness of the plastic sheet with water in the middle. On the top floor, the plastic sheeting is the wrapping all the way to prevent blood from being left on the road.

It needs to be folded to an appropriate size. If you wear latex gloves on site, no one will see it. You can buy plastic cloth to wear gloves, and you will probably be discovered immediately.

Taking out his mobile phone, Zhou Ning directly dialed Xu Dayuan's mobile phone, and Xu Dayuan came to the forensic anatomy room not long after.

"Xu Bureau, look here. Sister Cui used a special method to find Li Hua's fingerprints on the plastic sheeting. On the plastic sheeting of the second and third deceased, the imprint of clubbing fingers was also found. I think Li Hua can be interrogated. The murder weapon It has already been found. Whether you can find anything after sending it for inspection depends on your luck.

The other is Ai Qingsong's latex glove fingerprints with clubbed fingers. This can be compared with his finger shape. Although it cannot be regarded as a definitive proof, there are very few people with such characteristics. A person who is seriously ill and has only a few months to live, maybe Will tell the truth. "

Zhou Ning pointed to the picture on Xiaoqu's computer, and continued:

"One more thing, we found a sign, and after processing the image, we found that it was the sign of No. 29 Hongqi Road. Forensic doctor Bai consulted her father. This place is within the scope of demolition, next to the Hongqi Road community, and the property rights belong to Haichanglong. I think I can go here and have a look."

Xu Dayuan patted his head.

"It's no wonder that Zhenshan and the others did a blanket search, but they didn't find anything special. It seems that the location of our analysis is slightly off. If it's okay, I'll arrange to arrest people. I'll investigate the scene tomorrow. As for Ai Qingsong, I'll contact Lao Huang now. , see if we can get people back."

Liu Yufei raised her hand.

"Leader, I want to go to Shanghai to meet Ai Qingsong. How do you contact me here? If your health permits, we will bring people back for investigation. If your health does not permit, I will interrogate you on the spot, and then video-connect with you. what do you think?"

Xu Dayuan thought for a while, then nodded.

"Ask Xiao Zeng to cooperate with you, and then bring two more people with you, and ask the hospital to cooperate. I will ask Li Chunbo to issue a co-investigation letter, and the arrest warrant will be passed to you later. However, he is in such a physical condition that it is impossible to detain him. After this I will report."

Liu Yufei nodded, dialed Xiao Zeng's phone, and walked out while talking, while Xiao Bai scratched his head.

"Why won't the leader let me follow?"

"What are you going to do? Are you making trouble? Are you able to interrogate, or can you cooperate with Yu Fei's actions? Don't be in a daze and hurry up and send the things that Director Zhou is going to send to the inspection department. On the way, make contact with them first, and do your best. All you can do is help, you know?"

Xiaobai nodded, not daring to talk nonsense, he knew that he was not capable enough, and he was always doing more harm than good, so he quickly shut up.

Da Zhao and Yang Xuetong have already packed all the murder weapons and various things that need to be submitted for inspection. Of course, the plastic sheet that wrapped the murder weapon is not missing, they are all carefully packed, and the contents that need to be inspected are written.

Sun Gaotie and Zhu Xingxing helped and sent the things out together. There were not many people left in the room. Xu Dayuan glanced at the house number and frowned.

"I was surprised to find Li Hua's fingerprints. She didn't attract my attention much, but Zhu Yufen felt that when talking about Zhu Kelin, she seemed a little abnormal. How should I put it, it seemed that there was hatred in her bones. "

Liu Yongxin nodded.

"I feel the same way. Zhu Kelin took the child back and took blood for comparison."

Hearing this sentence, Zhou Ning was taken aback for a moment, and Liu Yongxin pushed Zhou Ning when he saw this.

"What's wrong with you, apprentice? Did you think of something?"

Zhou Ning pursed his lips, and Xu Dayuan said first:
"It's been investigated to this extent, you can just say what comes to mind, we are not in a meeting, we need to talk about evidence, tell me what you think, can't I judge?"

"I remember Zhu Yufen said that after she was picked up by her aunt, her aunt didn't treat her very well, just like a nanny, but changed her surname to become the adopted daughter of Zhu's family, and then her cousin died and her aunt committed suicide, Zhu Kelin went crazy to her, Drinking talisman water and other messy operations have been tossing for half a year.

Then she brought back a child who was less than one year old. Zhu Yufen talked about it calmly, but I felt that she was full of hatred, not at the beginning, but when she said that her aunt was not good to her.

I always feel that this child has something to do with Zhu Yufen, but this seems absurd, and there is no evidence, but her eyes are full of hatred. "

Liu Yongxin widened his eyes, approached Zhou Ning and said in a voice that the three of them could hear:
"Wait, you're saying that Zhu Kelin messed around with Zhu Yufen, so her aunt treated her badly, but she dared not speak out, and she didn't want to bear it when her son died, so she chose to commit suicide, and Zhu Kelin felt that it was because she didn't money, so let the son die and the wife commits suicide.

Because of this, he started to do whatever he could to get the Haichanglong Company and so on. Then the child he brought in later may belong to Zhu Yufen?It's a bit messy and I'm running out of brains. "

Zhou Ning rubbed his nose. In fact, he just had an idea, and Liu Yongxin didn't have so many bloody plots in his brain. children.

Xu Dayuan raised his hand.

"It's a bit messy. Let me explain. Zhu Kelin's son and Zhu Yufen, a high school kid, may have been born to both of them. Do you suspect that Zhu Yufen was also involved?"

Zhou Ning helped his forehead, this brain supplement is already a little too much.

"I don't know, I just suspect that Zhu Yufen is not ignorant. She may not be involved in the death of the three people and Hai Changlong's matter, but she must know about the murderer's matter and even help them."

Xu Dayuan nodded.

"No nonsense, I'll send someone to get blood from these two boys. Did the few people who came before all have blood samples?"

Zhou Ning hummed.

"I kept it, but how can we compare it without Zhu Kelin's DNA?"

Xu Dayuan smiled.

"Not to mention, this really happened. When Li Libo came here before, he said that they had dealt with a traffic accident, and Zhu Kelin was one of the injured. Their company sued the driver who caused the accident, saying that the other party did not call the police to rescue him, and fled the scene directly.

The other party applied for it and did a DNA comparison. The driver of the other party had Zhu Kelin’s blood on him. The case happened in June 2011. I asked Cui Lili to retrieve the archives and compare them later. You asked Zhu Xingxing and Sun Gaotie to follow. , Let's go to collect blood and send it for inspection. "

Zhou Ning hurriedly called to order, and just hung up the phone, Da Zhao ran back with a grin.

"Does this still need to be sent for inspection? Do I need to call Xiaobai back?"

Liu Yongxin waved his hand.

"Don't talk sarcastic here. Xiaobai is in a hurry to send for inspection. He wants to check the DNA and the traces left on it, and it's too old. I don't know if we can extract effective information. Come out, let them go for a while."

Zhou Ning looked at Xu Dayuan. Zhu Yufen's child was originally named Fang Yunhai, but later changed his surname to Zhu Yunhai. He lives in No. 92 Middle School and lives in the second year of high school. This kid is easy to find. Zhu Kelin's son was brought back in 1991, and his birth date is In 1992 or 20, the age was between 21 and [-], and I was probably in college at this age.

"Xiao Qu, look up the identity information of Zhu Kelin's son, and then see where he studies?"

Xiao Qu hurriedly operated and searched. He was a little surprised when he saw the address, so he quickly turned the computer over.

"I found it. His name is Zhu Yunping. He was born on February 1992, 2. He is a student at Qin University. He is a junior student in the Department of Computer Science. Do you need a phone number?"

Big Zhao burst out laughing.

"I'm going to find someone to find my lair, isn't it this person?"

Xiao Qu hurriedly introduced it, and Da Zhao was stunned for a while, with a gossip on his face, but seeing that the three of them had no intention of speaking, they poked Zhou Ning's arm.

"Let Teacher Xia get in touch. She's not taking care of students recently, so it's easy to find an excuse to draw some blood."

Both Xu Dayuan and Liu Yongxin looked at Zhou Ning. Zhou Ning took out his mobile phone and called Dr. Lu. He didn't want Xia Momo to do such a thing.

I explained my meaning to Dr. Lu, and the other party readily agreed. As for the excuse that Dr. Lu had already thought up for Zhou Ning, Dr. Lu even took responsibility for the examination, and hung up the phone after speaking.

Liu Yongxin patted Zhou Ning on the shoulder.

"You kid is worried about Mr. Xia, afraid of being retaliated by others in the future?"

Da Zhao leaned over, squeezed between Zhou Ning and Liu Yongxin, grinned and said:

"Uncle Liu is envious. Let me tell you something serious. I won't wait for tomorrow. I will take someone to see No. 29 Hongqi Road now."
