Chapter 310 No. 29 Hongqi Road

Zhou Ning opened his eyes and subconsciously spoke.

"No, the order is wrong."

Liu Yongxin turned his head to look at Zhou Ning. He knew that Zhou Ning was used to deducing all the traces in his mind, but he was confused about what was wrong.

"What order is wrong?"

"I have always believed that the deceased was acquainted with the murderer, was suddenly attacked while talking or getting together, and then died of suffocation or drowning.

If you are attacked while standing or sitting, even if there is no resistance, during the fall process, the other side that was attacked will fall due to the impact force, resulting in a hedge fracture. You can see that the temporal part on the other side of the deceased is intact, which is the same as Our analysis does not match.

Then, judging from the wound site of the attack, the deceased Zheng Chuguang may have been attacked and fainted while lying on his side, and then he was strangled and suffocated to death, his neck was cut off to let blood, and finally he was cleaned up and put on clothes. "

Having said that, Zhou Ning paused, looked at Zhu Xingxing to the side, and waved at her.

"Zhu Xingxing went to check the three autopsy reports to see if there were blood stains on the clothes, especially the rubbing marks on the inside."

Zhu Xingxing jumped out, and everyone was stunned. They were confused by Zhu Xingxing's reaction. They didn't know why the girl ran away. After all, all the reports were stored in Xiaoqu's computer. Before Zhou Ning could say more, Zhu Xingxing had already returned with the whiteboard.

Da Zhao twitched his cheeks, suppressed a smile, and hurried over to help.

Panting, Zhu Xingxing adjusted the direction of the whiteboard, pointed to several places and said:

"The clothes of the three deceased were intact, and no large amount of blood spatter was found, but on the innermost layer of clothing, there were rubbish-like blood stains.

In addition, from the time photos, it can be seen that the sleeves of the shirt of the deceased No. [-] were hoarded at the elbow. I remember that the forensic doctor Bai said that the clothing and related evidence of the deceased were kept in the evidence room here. "

After saying this, Zhu Xingxing saw Zhou Ning looking at her, she was very smart this time, so she quickly raised her hand.

"I'll go to Forensic Doctor Bai and get the physical evidence. We mentioned before that we need the physical evidence of this serial murder case, but after we got it, we were busy with other things at the time, so we put it down."

As he said that, Zhu Xingxing had already gone out to make a phone call. After a while, Bai Hua walked over with a box in his arms, followed by two criminal policemen. Bai Hua put down the things and introduced to Zhou Ning.

"The last meeting said that the physical evidence needs to be sorted out. I have found them separately. The physical evidence found at the three scenes is here. All of them have been re-photographed. The plastic cloth inside and the suspected blood on the clothes have been sampled.

As for the plastic cloth, I have sent someone to the laboratory to see if we can use the latest method to extract fingerprints. After all, the technology back then was limited. If you are in a hurry, Director Zhou, I can contact Section Chief Cui now. "

Zhou Ning shook his head. It seemed that Bai Hua was also paying attention. She was busy here and didn't pay too much attention to her. She was able to keep up with their progress and had already been sent for inspection. This ability is remarkable.

"Thank you, Da Zhao and Yang Xuetong checked the clothes of the deceased, starting with Zheng Chuguang."

The two started to move, Liu Yongxin had already dialed Cui Lili's mobile phone and asked in a low voice, Cui Lili on the other side was very polite, so Liu Yongxin hung up the phone.

"The inspection report has been sent to the mailbox. Xiaoqu opened it and took a look. In addition, Cui Lili used many methods to try to extract the fingerprints on the plastic cloth. Finally, he found a few with the 8-hydroxyquinoline method and sent them together. It is complete, and it is no problem for comparison."

Zhou Ning breathed a sigh of relief. Sister Cui is always timely. It is not easy to extract old fingerprints. Every deceased person is covered with plastic sheets. Zhou Ning does not know the reason. After all, this thing is not heavy-duty. Blood on the murderer?

Can't figure it out, Zhou Ning didn't think about it either, Xiao Qu had already printed out the report, Sun Gaotie ran to pick it up and handed it to Zhou Ning.

Zhou Ning glanced at the shirts or vests of the three deceased with blood stains, all of which belonged to him, and there were few scratches on the trousers and coats. Looking at the photos of the clothes again, Zhou Ning became more firm in his judgment. He was put on clothes after being beheaded and bled.

Turning to the end, several fingerprints are indeed incomplete, with different shapes and black and white edges, but the middle 70% can still be compared. As Cui Lili said, it is not enough to search for suspects with it, but the comparison is still more than enough .

"Compare Xiaoqu, Li Hua, Zhu Yufen, Ai Qingsong, Fang Guoying, Li Hua's husband Chen Guoqing, the three classmates who came here before, and Zhu Yufen's ex-husband, you need to search for this information, I don't know Zhu Yufen Ex-husband's name."

Xiao Qu gave an OK gesture, and then started to get busy.

Zhou Ning checked the skulls of the remaining two deceased. Like Zheng Chuguang's skull, there was no hedging fracture. The only difference was that Yu Guangyao's injury was on the occipital, and this time the force was too great, and the occipital bones had broken .

Zhou Ning picked up the fragments and compared them. They can be put together completely. However, the wound was not caused by the blade of the axe. It was caused by hitting directly with the side of the square head. There is still no hedging fracture on the forehead.

It's a pity that there is only a skull. If there is brain tissue, it will be easier to observe the extent of the damage.

Da Zhao had finished his work at the moment, and had already placed the selected items on the table. Zhou Ning took a look, except for three axes, green nylon rope, which was made of the same material as binding the three people, and a wooden sign .

The material and style of the ax are basically the same, but the size is slightly different. There are blood stains on the square blade and the handle, and what is surprising is that the ax is wrapped in plastic cloth. Da Zhao wants to sweep the soil on it. They were all stopped by Zhou Ning.

"Don't open it, just send it to Sister Cui together with the box. Although it was buried in the soil, it was wrapped in plastic sheeting. It's still an environment where the temperature and humidity don't change much. Maybe something can be extracted from it.

The dead were all beaten into unconsciousness, and then killed and beheaded. Have you ever thought about why this is? "

Da Zhao blinked.

"I don't even need to think about it, torture, isn't this revenge for Cui Yushang?"

Liu Yongxin rolled his eyes and pushed Da Zhao away.

"It's so stupid, let you use your brain to think about it, why don't you know how to use your brain more? According to the previous analysis, the murder and dumping of the body was done by at least two people, and it took 19 years, just because you bullied a big fool? How much can they do for this stupid big man?"

Such rhetoric stunned the people present, Zhou Ning looked at Liu Yongxin with a smile, the master is the master, and ordinary people can't keep up with this kind of thinking.

"Uncle Liu and the boss mean that the murderer deliberately led us to investigate in this direction?"

After hearing Zhu Xingxing's words, Zhou Ning nodded.

"Not accurate, but it does have this effect. Childhood bullying can have a profound impact on a person, but the premise is that the master of hatred is alive. If Cui Yushang is not dead, then in today's case, we may list Cui Yushang as a suspects.

Whether it is a relative or a friend, they will forget all the hurts as time goes by, so I think among these people, there must be someone who has been hurt by these three people, and maybe this kind of hurt has lasted for many years.

Wait for Bureau Xu's investigation, I think the first scene will be found soon, and I have another doubt, but this still needs to wait for Bureau Xu's results. "

Da Zhao scratched his head.

"You're ruthless, you're a trickster!"

"That's not true. Bureau Xu and Tao Da analyzed the center point of the corpse dumping site before, and found that this location happened to be the location of the Hongqi Road community back then. This place has been designated for demolition, and it has been tossing for several years, because the nail house has been vacant all the time. , this is very likely to be the first scene."

"Why didn't you tell us to follow?"

"No hurry, let them go through it first."

Zhou Ning picked up the wooden sign and looked at it. It seemed that there were words on it. Da Zhao swept it with a brush, and the floating dirt was gone. There were some remaining paint marks in the middle of the wooden sign. Moved a little farther, Da Zhao yelled:
"I said why it looks so familiar. This is the house number. The house numbers in the 80s are all wooden signs like this. The street and number are painted on it, but the paint is all gone."

Xiaoqu raised his hand.

"Show me the wooden sign. I'll take a picture and use software to scan and sharpen it."

Da Zhao quickly sent the wooden sign over.

"Fingerprint comparison failed?"

Seeing Zhou Ning's puzzled face, Xiao Qu quickly pointed to another computer.

"Analyzing. After all, the fingerprints are not clear. I just finished processing the pictures of these fingerprints. It will be over in 10 minutes."

Zhou Ning walked over, Xiao Qu analyzed and processed the scanned pictures, and then flicked his fingers on the keyboard. The picture of the wooden sign turned black and red for a while, and finally some handwriting appeared under the strong contrasting light.

"No. 29, Hongqi Road? What is this place?"

Xiaoqu hurriedly searched the map of the 90s, and found the location of No. 29 Hongqi Road, which happened to be a courtyard at the south gate of the Hongqi Road community, but the map did not mark where it was.

Bai Hua came over to take a look, and everyone gave way to her. After all, she is a local. After thinking about it, Bai Hua suddenly realized:

"Let's think about it. I walked here before. It seems to be some kind of factory, but the door is closed. I don't know if it is the tertiary industry of the old state-owned enterprise or somewhere, but the door is still intact. Let me ask my dad, my dad It was retired from the Construction Bureau."

Bai Hua hurriedly dialed the phone, asked some questions, and quickly raised her head to repeat.

"My dad said that this was originally the site of a printing factory. When the Hongqi Road community was built, it was re-planned. Inside was a concave-shaped office building. It was the office area of ​​Haichanglong at that time, but later around 1990, Haichanglong moved to Their building is gone, and the place is idle, and has not been resold."

"Don't hang up, ask your dad, this Hongqi Road community has been demolished for several years. Is this a project undertaken by Haichanglong Real Estate?"

Bai Hua nodded after asking.

"Yes."

Everything seemed to be getting clearer and clearer. At this moment, the computer next to Xiao Qu beeped twice. Xiao Qu glanced at it and shouted excitedly:

"Director Zhou, look, the fingerprints have been compared!"
