Xu Dayuan nodded.

"It's not that it's not a no-gain, just now Liu Yufei called, the bodies of the three deceased have not been preserved, and they have all been cremated, which makes it more difficult for us, let's go and see how Zhou Xiaozhou is going, didn't he come out to eat lunch?"

Da Zhao shook his head.

"I didn't dare to send the lunch in, I put it at the door, I just let Xiaoqu take a look, and I took the lunch in to eat, but the person didn't come out, Xiaoqu looked at the door for a while, saying that it was densely written on the whiteboard, and it was estimated that he was analyzing the commonality of the three deceased."

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

"You can't help Zhou Xiaozhou here, you didn't follow the investigation, and you haven't gone to the interrogation, what did you do just now?"

Da Zhao was stunned for a moment, stalking his neck, looking innocent.

"I said leader, you and I are not idle, isn't this following Xiaoqu to inquire about that Haichanglong Group? This group is very interesting, since Zhu Kelin took over, the original industrial industry was sold, entrusted management and entrusted management, and now there are two parts left, one is real estate and the other is a trading company.

According to Li Fang's sister Li Hua, Hai Changlong was obtained by Zhu Kelin in the name of insolvency, and we studied it and found that Hai Changlong was Zhu Kelin, who owned 13% of the shares, after 94 years of insolvency, and Zhu Kelin, who filed for bankruptcy reorganization.

Then Haichanglong began to be injected with more than 40 million yuan, and even purchased a lot of land plots and entered real estate, and the Liuyuan community in which the No. 3 deceased participated was developed by Haichanglong, and he participated in a lot of municipal projects, building roads, building bridges, and renovating old houses.

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

Xu Dayuan paused, he didn't expect Da Zhao and them 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 bumped Zhou Ning on the shoulder.

"Our leader's concern is a little bit empty, the inquiry here is over, what's wrong with you here?"

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

"I compared the cause of death of the three deceased, the condition of the scene where the bodies were dumped, the features, the location of the eucalyptus, and the state of the severed head, and found some problems.

You see, plastic sheets were laid under the bodies of the three deceased, and there was dew and rain on the plastic sheets, but there were not many blood stains, which means that the three people were cut off and bloodied, and then transferred to the scene of the dumping of the bodies, and there were no blood splatters found on the clothes of the three people.

Although there was pulmonary edema, I think that the first deceased died of mechanical asphyxiation, and the second deceased died of drowning, as for the cause of death of the third deceased, I was inclined to insulin overdose, and when I looked at the white birch autopsy here, it was found that the deceased had a pinhole on the outside of his upper arm.

At that time, the area was not sliced and analyzed by local drug tests, but the deceased's blood sugar was 2.7, and I don't think it was caused by starvation, because excessive starvation will cause blood sugar to rise, which is clinically called the somogyi phenomenon. ”

Xu Dayuan was stunned.

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

Zhou Ning nodded.

"I remember, Li Fang's sister Li Hua is a nurse in the emergency department, did she and that Zhu Yufen come over in the afternoon?"

"It's not here yet, Xiaobai has picked up Li Hua, go to pick up Zhu Yufen by the way, and come over later, you continue to talk about your discovery."

Zhou Ning snorted and pointed to the place where the three of them threw their bodies.

"Speaking of the place where the body was dumped, the No. 1 deceased Zheng Chuguang was placed on the opposite bank of the bridge where Li Fang fell to his death, the deceased had no abrasions on his body, there were indentations on the left and right armpits, and the pattern was not clear, but the threads could be seen, I think this was caused by the deceased being lowered from the bottom of the bridge with a rope.

The murderer had a transport vehicle, and it was fixed with a rope tied to the car, and the deceased and the murderer were lowered from the edge of the embankment, and then the murderer put the deceased in a posture and came up along the rope, and the deceased was found to have rained the day before, so there were no traces on the ground.

As for the second deceased Yu Guangyao, he was placed in the back seat of the car, and the car was parked in the backyard of the Cultural Palace, although the north side of this is a hotel, there is no surveillance, and there is no doorman, but I looked at the photos of the deceased's vehicle, Xu Ju, you look at the driver's chair, which is obviously closer to the co-pilot's chair.

With the height of the deceased of 185, plus the weight of 178, this space is definitely not enough for him to use, according to the distance reflected in the scale, the front of the seat fits almost vertically, Da Zhao once said that Zhu Xingxing's habit of driving, I think many women like to adjust it like this, right? ”

Da Zhao took a closer look, and then kept nodding.

"At this distance, Zhou Xiaozhou's legs can't reach in, I think the last person to drive the vehicle is similar in height and posture to Zhu Xingxing, with a height of less than 162 and a weight of less than 90 pounds, and so on There is still a possibility."

Da Zhao suddenly paused and looked at the two.

"There is also a possibility that when the murderer deliberately left, the seat was adjusted to confuse the police and let us focus on the woman, but the inside of the vehicle was not investigated? I didn't see the investigation report mentioning that the fingerprints of the second person were found in the car? ”

Zhou Ning frowned, but still nodded.

"Da Zhao said, do not rule out this, I carefully read the survey report, the vehicle survey was carried out six times, fingerprints were checked everywhere that could be touched by hands, the vehicle was carefully cleaned, the undercarriage was clean, only the fingerprints of the deceased and some glove fingerprints were found."

Xu Dayuan rubbed his chin and said:

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

Zhou Ning nodded, Da Zhao had already taken the photo, and looked at his hand against 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, you can tell that this is a characteristic of male fingers, even if my hand is large, this person's hand is bigger than mine, and the fingers are thicker."

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

"Do you see what's wrong with this fingerprint? There is a gap between the finger and the second segment, and the abdomen of the finger is thicker and more rounded than the second segment, and deeper nail marks can be clearly seen at the tip. ”

With Liu Yongxin's prompt, Zhou Ning carefully observed the photo, then raised his hand and slightly bent the first section of his fingers, Zhou Ning paused, raised his head and said with a surprised face:

"Clubbing, Master, are you saying that this person is clubbing?"

Liu Yongxin nodded.

"The clarity of the photo is not high, but it can be judged through these fingerprints, this person is clubbing, I have done a eucalyptus before, the murderer left such fingerprints, I asked the expert of the First Affiliated Hospital of Qindao at that time to consult, and finally examined the person and found that he was early lung cancer."

Both Android and Apple are available. 】

Xu Dayuan was also a little surprised, this discovery can be regarded as a kind of discovery, but after recalling it, it seems that he didn't find anyone with such fingers, so he hurriedly asked:

"You mean, at least the murderer who left the marks in the car of the second deceased may be a male, this person is clubbing, and he may be an early patient with lung cancer?

The eucalyptus of Yu Guangyao happened in 2000, and it has been 12 years, and the early stage of lung cancer is enough to live to this time, right? ”

Zhou Ning shook his head.

"Clubbing is not necessarily lung cancer, heart disease, respiratory disease, digestive system disease, chronic poisoning, etc.

Moreover, clubbing is generally not formed suddenly in a short period of time, if it is a clubbing of a unilateral limb, or a single finger, it is generally related to a nearby vascular lesion, but looking at the distribution of this fingerprint, all the fingers of the person have this characteristic. ”

Xu Dayuan smiled.

"Nothing else, at least one of the killer's characteristics has been found now, and this person has clubbing."

Several people nodded their heads, and Zhou Ning continued:

"Then I'll go on, the third deceased Zhang Qiujian was found on the roof of Building No. 7 in Liuyuan Community, I won't say anything about the same place as the first two deceased, I studied the survey report, which said that to reach the roof of Building No. 7, you need to go up from the skylight on the top of Unit 3.

The height of the skylight from the top floor slab is 3.3 meters, the abdominal circumference of the third deceased is 3 feet 4, the size of the skylight is 70*70 cm, and it cannot be dragged up to the top floor on the back.

And under the skylight, there is no ladder mark, and on the wall and metal handrail, there is a finger overprint, you see, this finger imprint is exactly the same size as the one left on the car of the second deceased, Yu Guangyao.

Zhang Qiujian's body was found on March 15, 2006, and people who don't work outdoors don't wear a lot, but people who work outdoors still wear down jackets.

We look back at the first deceased Zheng Chuguang died of mechanical suffocation, the No. 2 deceased Yu Guangyao drowned, and the No. 3 deceased Zhang Qiujian died of mechanical suffocation, whether it was suffocation or drowning, they would not struggle without struggle, but they did not have resistance injuries on their bodies, does that mean that they had lost consciousness before their near-death? ”

Liu Yongxin narrowed his eyes slightly.

"You think they're drugged or stunned, but the poison test doesn't show anything unusual."

Zhou Ning shook his head.

"It's because the poison test didn't find anything abnormal, I ruled out this, after all, the operation of ether covering the face is impossible to make Yu Guangyao and Zhang Qiujian, people of this weight, faint suddenly.

Then their hands will also subconsciously scratch and there will be residues, or clean up the remaining marks, I think they get a hard blow to the head, or they get an electric shock in the head. ”
