Xu Dayuan nodded.

"It's not a loss. Liu Yufei just called and the bodies of the three deceased were not preserved and had been cremated. This has increased the difficulty for us. Let's go and see how Zhou Xiaozhou is doing. Didn't he even come out to eat lunch?"

Da Zhao shook his head.

"I didn't even dare to send the lunch box in, so I put it at the door. I just asked Xiaoqu to take a look. I took the lunch box in and ate it, but the person didn't come out. Xiaoqu looked at the door for a while and said that it was written on the whiteboard, and I guess he was analyzing the commonalities of the three dead."

Xu Dayuan had already grabbed the door handle of Zhou Ning's office, but he stopped and tilted his head to look at Da Zhao.

"You can't help Zhou Xiaozhou, and you didn't follow the investigation. You haven't been to the interrogation yet. What did you do just now?"

Da Zhao was stunned, thorning his neck, looking innocent.

"I said to the leader, you and I are not idle. Isn't this what kind of Haichanglong Group followed Xiao Qu to check out the Haichanglong Group? This group is quite interesting. After Zhu Klin took over, the original industrial industry was sold and the entrusted management was entrusted management. Now there are only two parts left, one is real estate and the other is trading company.

According to Li Fang's sister Li Hua, when Hai Changlong was obtained by Zhu Klin, he was obtained in the name of insolvency. We studied it and found that after Hai Changlong was insolvent in 1994, Zhu Klin, who owned 13% of the shares, applied for bankruptcy reorganization.

Then Hai Changlong began to inject more than 40 million yuan, and even purchased a lot of land and entered the real estate industry. Moreover, the Liuyuan community where the deceased No. 3 participated was developed by Hai Changlong, and municipal projects were even more involved in road construction, bridge building, and old house renovation.

By the way, the municipal project that Yu Guangyao, the second deceased, was involved in, was part of the project subcontracted by their group. However, even if Yu Guangyao was killed and was suspected of bribery, Hai Changlong was not affected."

Xu Dayuan stopped moving, but he didn't expect Da Zhao and the others to make such a discovery.

Just as he was about to speak, the door was opened, and Zhou Ning walked out.

"Zhou Xiaozhou, have you had lunch?"

Da Zhao grinned and hit Zhou Ning's shoulder.

"Our leader's concern is a little bit weak. The inquiry here is over. How are you doing here?"

Zhou Ning let the door open, Xu Dayuan and the others walked into the room, and the three of them walked to the whiteboard together. Zhou Ning took a sip of water before saying.

"I compared the causes of death of the three deceased, the scene of the body being thrown, the characteristics of the crime scene, and the status of the head being cut off one by one, and found some problems.

Look, there are plastic cloths under the bodies of the three deceased. There is dew and rain on the plastic cloth, but there is not much blood stain. This means that the three of them have their heads cut off and blood was removed and transferred to the scene of the body throwing. Moreover, no blood was found on the clothes of the three of them.

Although there is pulmonary edema, I think the deceased No. 1 died of mechanical asphyxiation, while the deceased No. 2 drowned. As for the cause of death of deceased No. 3, I tend to overdose insulin. When I looked at Baihua's autopsy, I found that there was a pinhole on the outer side of the upper arm of the deceased.

At that time, the place was not sliced ​​and performed local drug examination and analysis. However, the deceased's blood sugar was 2.7. I don't think it was caused by hunger, because excessive starvation will cause blood sugar to rise, which is clinically called the Somogyi phenomenon."

Xu Dayuan had a meal.

"You mean, Zhang Qiujian, the third deceased, died because he was injected with excessive insulin?"

Zhou Ning nodded.

"I remember that Li Fang's sister Li Hua is an emergency department nurse. Did she and Zhu Yufen come in the afternoon?"

"Before you arrived, Xiaobai picked up Li Hua, went along the way to pick up Zhu Yufen, and rushed over later, and you will continue to talk about your discovery."

Zhou Ning nodded and pointed to the place where the three of them threw the body.

"Along with the place where the body was thrown, Zheng Chuguang, the deceased No. 1, was placed on the opposite side of the bridge where Li Fang fell to his death. The deceased had no scratches on his body, there were indentations on his left and right armpits, and the patterns were unclear. However, the threads could be seen. I think this was caused by using a rope to lower the deceased's bottom of the bridge.

The murderer had a transport vehicle, and he tied a rope to fix it with a car, and put the deceased and the murderer down from the edge of the embankment. The murderer then placed the deceased's posture and came up along the rope. The deceased was found raining the day before, so the traces on the ground were not retained.

As for Yu Guangyao, the second deceased, he was placed in the back seat of the car. The car was parked in the backyard of the Cultural Palace. Although there was a hotel on the north side of this place, there was no surveillance and no guard. However, I saw the photos of the deceased's vehicle. Director Xu, you see the driver's seat, which is obviously ahead of the passenger seat.

With the deceased's height of 185 and his weight of 178, this space is definitely not enough for him to use. According to the distance reflected on the scale, the front of the seat is almost vertically fitted. Da Zhao once said that Zhu Xingxing's driving habits, I think many women like to adjust this way, right?"

Da Zhao leaned closer and looked at it, then kept nodding.

"At this distance, Zhou Xiaozhou couldn't even stretch his legs. I think the person who drove the vehicle in the end was similar to Zhu Xingxing's height and body shape. He was less than 162 and weighed less than 90 kilograms, and there was still a possibility."

Da Zhao suddenly stopped and looked at the two of them.

"There is another possibility, when the murderer deliberately left, he adjusted the seat to confuse the police. Let us focus our search attention on women, but wasn't the inside of the vehicle inspected? I didn't see the survey report, and mentioned that the fingerprint of the second person was found in the car?"

Zhou Ning frowned and nodded.

"What Da Zhao said is not ruled out. I looked at the survey report carefully. The vehicle survey was conducted six times, and the fingerprints were checked where the hand could touch. The vehicle was carefully cleaned up, and the bottom of the seat was clean. Only the fingerprints of the deceased and some glove fingerprints were found."

Xu Dayuan rubbed his chin and said:

"You mean, the murderer was able to get close to Yu Guangyao's vehicle. Before Yu Guangyao died, he specially cleaned and scrubbed the car carefully. When he sent the deceased to the backyard of the Cultural Palace, he also wore gloves, so he did not leave any fingerprints."

Zhou Ning nodded. Da Zhao had already taken off the photo and looked at his hand in the scale. This size was thicker than his fingertips, corresponding to the distribution of finger prints. Da Zhao looked surprised.

"Although it is a glove fingerprint, it can be distinguished. This is the characteristic of male fingers. Even if my hands are big, this person's hands are bigger than mine and their fingers are thicker."

Liu Yongxin walked in at some point, took the photo from Da Zhao's hand, looked carefully, took the pen from Zhou Ning's hand, pointed to a few gloves and fingerprints and said:

"Do you see what's wrong with this fingerprint? There are spaces for pressure on the focus area of ​​the finger belly and the second section, and the finger belly is thicker and rounder than the second section, and deeper nail marks can be seen at the tip."

With Liu Yongxin's prompt, Zhou Ning carefully observed the photos, then raised his hand and bent the first section of his finger slightly. Zhou Ning paused and raised his head and said in surprise:

"Parse-shaped fingers, Master, are you saying, this person is club-shaped fingers?"

Liu Yongxin nodded.

"The clarity of the photo is not high, but it can be judged by these fingerprints that this person is clubbing. I had a case before, and the murderer left such fingerprints. I consulted with experts from the First Affiliated Hospital of Qindao at that time, and finally checked the person and found that he had early lung cancer."

Xu Dayuan was also a little surprised. This discovery was also a kind of discovery. However, after recalling it, he seemed that he did not find someone with such fingers. He quickly approached and asked:

"What you mean is that at least the murderer who left traces in the car of the second deceased may be a male. This person is clubbing, and may be an early stage patient with lung cancer?

Yu Guangyao's case happened in 2000. Twelve years have passed. It's so difficult for the early stage of lung cancer to survive to this time, right?"

Zhou Ning shook his head.

"The clubbing finger is not necessarily caused by lung cancer, heart disease, respiratory disease, digestive system disease, chronic poisoning, etc., but the clubbing finger is one of the most common extrapulmonary signs in lung cancer.

Moreover, clubbing fingers generally do not suddenly form in a short time. If clubbing fingers appear on one side limbs or a single finger, it is usually related to the nearby vascular lesions. However, judging from the distribution of this fingerprint, all fingers of this person have this characteristic."

Xu Dayuan smiled.

"No matter what else, now I have at least one of the characteristics of the murderer, who has clubbing fingers."

Several people nodded, and Zhou Ning continued:

"Then I will continue to say that Zhang Qiujian, the deceased No. 3, was found on the roof of Building 7 in Liuyuan Community. I will not talk about the same place as the previous two deceased. I studied the survey report and said that to reach the roof of Building 7, you need to go up from the skylight on the top of Unit 3.

The skylight is 3.3 meters away from the top floor slab. The abdomen of the deceased No. 3 is three feet and four feet apart. The skylight is 70*70 cm in size and cannot be pulled up to the top floor by someone carrying it. Corresponding to the autopsy report, I also found a thread mark under Zhang Qiujian's armpit, which is also very shallow.

There is also no mark of a ladder under the skylight, and there are gripping fingers on the walls and metal handrails. Look at this finger mark, it is exactly the same size as the car left by Yu Guangyao, the second deceased.

Zhang Qiujian's body was discovered on March 15, 2006. People who do not work outdoors do not wear many, but people who work outdoors still wear down jackets. I think this is how Zhang Qiujian's respiratory down came from.

Let’s look back at the deceased No. 1, Zheng Chuguang, who died of mechanical asphyxiation, Yu Guangyao, who died of No. 2, and Zhang Qiujian, who died of mechanical asphyxiation, will not struggle without any struggle, but their lack of resistance to injuries. Does that mean that they have lost consciousness before they are dying?"

Liu Yongxin narrowed his eyes slightly.

"You think they were drugged or fainted, and there was no abnormality in the toxic substance detection."

Zhou Ning shook his head.

"It was because no abnormality was found in the poison detection, and I ruled out this. After all, the operation of ether covering his face would not make Yu Guangyao and Zhang Qiujian, the weight of people, suddenly fainted.
Chapter completed!
