Zhou Ning nodded.

"The autopsy and the on-site investigation report show that there are no traces of drag around the No. 1 deceased Zheng Chuguang, except for the plastic sheeting on the ground, no blood stains were found on the ground around him, and the deceased's head was beheaded.

It's really impossible for one person to do this, but it is impossible to judge whether the murderer is two men or a man and a woman, but the first scene of the death of the second deceased Yu Guangyao must be a woman, has his social relationship been checked? ”

Bai Hua turned around and rummaged through the file, took out a few records, and handed them to Zhou Ning.

"Yu Guangyao's social relationship is very complicated, his construction company owes a lot of money, all of which are triangular debts, Yu Guangyao had an accident, and after the construction of the substandard road section was compensated, his assets were also repaid, and his wife went to the city government many times to find it, and the punishment was not reduced.

It is said that in the end, the remaining more than 200,000 yuan was repaid after the court auctioned off a property of Yu Guangyao, in fact, Yu Guangyao has a lot of assets, and his family will not be unable to survive. ”

Zhou Ning exhaled, the three deceased were not kind, the first two deceased died too early, but the last deceased Bai Hua followed the investigation, she could know more.

Thinking of this, Zhou Ning asked:

"The first two deceased people will be put first, after all, the time is long, the last deceased Zhang Qiujian, do you have any opinion? I'm referring to your suspicions, not what is reflected in the autopsy report. ”

Bai Hua was silent for a moment, and when he looked up, his gaze was much firmer.

"Zhang Qiujian's death, involved a lot of things, Zhang Da followed the investigation of this eucalyptus, I followed the personnel of the Municipal Bureau Forensic Office, participated in the on-site inquest and autopsy, when the deceased was found, I felt that the deceased's posture seemed to be kneeling and begging for forgiveness, just because of the rain, the body leaned forward.

I don't know if you have visited Yue Fei Temple, although there is no head, but that posture is like the posture of Qin Hui in front of Yue Fei Temple, especially after investigating and dealing with the evidence of Zhang Qiujian's bribery, I feel that the murderer is punishing evil and promoting good, of course, I shouldn't say this, but Zhang Qiujian really deserves to die. ”

Zhou Ning followed Bai Hua's explanation and looked at the photos of Zhang Qiujian's killing.

It is true that Zhang Qiujian's state looks like he is kneeling, but his upper body is naked, and the bottom is covered with plastic sheeting, and with the effect of rain, it is easy to change his posture, but seeing the blood sugar value, Zhou Ning frowned slightly.

"Zhang Qiujian's previous physical examination report, have you checked it? This glycemic index does not match his posture, according to his posture, his limbs are slender and his belly is big, blood sugar, blood pressure and blood lipids will not be very low, does he keep taking insulin? ”

Shirakaba shook his head.

"I didn't get his physical examination report, Zhang Da sent someone to ask Zhang Qiujian's family, and his daughter-in-law said that Zhang Qiujian's blood pressure was only slightly higher than 140/90, and everything else was normal, especially blood sugar, I think the deceased may have been starved for a long time, so the blood sugar dropped to the limit, after all, the stomach was already completely emptied at the time of the autopsy, and there was no residue in the intestines."

Zhou Ning hummed, dialed Xu Dayuan's mobile phone, and the second bell rang and the other party connected the phone.

"When the Xu Bureau investigates the three deceased, can you check their physical examination records, I remember that this will be kept in the physical examination center for 30 years, and you can check it."

"Okay."

......

March 12th, 2012 at 10:22

In the conference room, Xu Dayuan looked around.

"Zheng Chuguang, Yu Guangyao, and Zhang Qiujian's social relations from primary school to university have been sorted out, and Xiaoqu will tell you the results of the data comparison after statistics."

"Okay, let me introduce, after two days of investigation, the three from primary school to university, transfer and transfer are counted, the same class of 321, 337, 386 people, a total of 1044 people, of which there are 7 people who have studied in the same class with the three people.

Of course, if they are released to the same grade, there are 174 people who have been in contact with the three people, and the three deceased were in the same Hai'an City Experimental Primary School when they were in elementary school, but they were in different classes.

Yu Guangyao and Zhang Qiujian lived in the Hongqi Road community together, and after investigation, Zheng Chuguang's grandfather's house was also in the Hongqi Road community, so I will live in this community together, and the people who studied in Hai'an Experimental Primary School like the three people also did a check, including six of the seven people. ”

As he spoke, Xiaoqu clicked on a table, which was a list of seven people, but the last one was lighter in color, and it was obvious that the six people in front of him were people from the same school and community as the three deceased.

Xu Dayuan stared at the list and waved his hand.

"Then you say, are these six people in contact, where are they? When can I come and assist with the investigation? ”

Tao Zhenshan hurriedly said:

"We received the news of Xiaoqu, began to contact these six people, through the household registration system inquiry, found five people, one phone has not been contacted, two of the five people are in the field, three people notified the afternoon to come to assist in the investigation, as for the content of the investigation did not say.

Two people from other places, one can rush back tomorrow, we made an appointment to go to the criminal police team in the morning to cooperate with the investigation, as for the other in Shanghai for medical treatment, advanced liver cancer, waiting for surgery, I don't know what to do, or I contact my counterparts in Shanghai, go over to help inquire? ”

Xu Dayuan looked at the time and waved his hand at Tao Zhenshan.

"Give me the phone number, call me now, Zhou Ning, do you have any questions that you have to ask?"

Zhou Ning thought for a moment.

"I want to know, when they were in primary school, did anything special happen in their experimental primary school and Hongqi Road community, did the three deceased people participate, or did they do anything bullying?"

Xu Dayuan nodded, dialed the phone directly, and the other party only answered the phone after a minute of ringing, and fed weakly.

"Hello?"

"Are you Ai Qingsong?"

"I am, who are you?"

"I'm Xu Dayuan from the Qindao Criminal Police Detachment, I just inquired, you and Zheng Chuguang, Yu Guangyao, and Zhang Qiujian used to be classmates, and you used to live together in the Hongqi Road community, we know that it is inconvenient for you to come to the scene when you are hospitalized in Shanghai, I want to ask you some questions, do you think it is okay now?"

The other party was stunned, as if he was recalling, and was also surprised that the police knew his current state, and then hurriedly said:

"It's convenient, anyway, I'm waiting for surgery in the hospital, I don't have anything special."

A woman's voice came from the other end of the phone, with a hint of dissatisfaction.

"Who is looking for you, doesn't this stop in the hospital? They've all fired you, and if there's anything else to hand over over and over again, let them contact me. ”

】

"Don't get involved, it's not the unit's business, the police are investigating a few of my classmates, you close the door first. Excuse me, officer, but go on, I'm here for my convenience. ”

In the end, there was obviously some asthma, Zhou Ning raised his eyebrows, the advanced stage of liver cancer is now obviously asthmatic, this is a manifestation of heart failure, it seems that this person's time is short, and the surgical effect in this state will not be very good.

"I think you know that all three were killed."

"Well, I've seen it on the news."

"In elementary school, you were all in the same grade, I wondered, was there anything special that happened with these three deceased people, or did they do something bullying?"

Ai Qingsong hummed twice.

"The elementary school thing is long enough, I only remember that when I was in the fifth grade, a classmate in my class died, he was hit by a train and died, that person was Cui Yushang, he didn't like to talk stupidly, and his academic performance was not good, he was a big and tall man of 1.75 meters.

I don't remember the specific day, I only remember that it was late autumn, and many boys made an appointment to go to the gourd bay diagonally opposite the school on Saturday to touch the fish, there was a spring in the bay, and the water was not frozen in winter, and there were a lot of small fish in it.

This Cui Yushang rode his father's 28 bars, when crossing the train track, he needed to carry the car across four or five train lines, I didn't see it when I went into the water by the bay, but I heard that he broke his foot, the bicycle was stuck on the train track, many people called him, he was like a demon, and he didn't let go.

But the train behind has turned a corner, many people watched him be hit by the train, it is said that the body was directly torn apart, the legs hung on the locomotive, and kept twitching, the person died at that time, to be precise, it was torn apart, but we didn't dare to look, all the children scattered and fled.

In the second week of class, the door of our class was blown open suddenly, and some male students were naughty, I don't know who shouted that Cui Yushang was back, and many girls were scared to cry at that time, and the teacher repeatedly ordered us not to mention this matter again, but the more so the students were more afraid.

However, our friends who went to play together said that Cui Yushang didn't want to care about the bicycle when he fell, and it was Zheng Chuguang, Yu Guangyao and Zhang Qiujian who shouted in the back, Cui Yushang, if your bicycle breaks your father, you can break your legs.

As soon as he shouted like this, Cui Yushang was persistent, his brain was not enough, and his father used a belt to whip him when he was fine, once the parent-teacher meeting was not over, and he was chased and pumped all over the yard at school, so Cui Yushang was frightened and naturally didn't dare to let go.

A month later, Cui Yushang's mother ran away, he was beaten by his father and couldn't stand running away from home, his father died in a drunk car accident, his grandmother went crazy, came to school every day to pick up Cui Yushang, fell into the ditch and drowned, only his sister was the most pitiful, was sent to live at his aunt's house, I heard that it was not good, but we never saw that sister again. ”

The people in the conference room were recording quickly, and Xiaoqu searched for Cui Yushang's information, but he didn't find this person's information, thinking about it, he was also a fifth-grade child, and at that time, he had not yet applied for an ID card, and all household registrations were recorded manually, and there was no network.

He hurriedly typed a few words and showed Xu Dayuan, Xu Dayuan nodded slightly, and continued to ask:

"What is the name of Cui Yushang's sister, do you remember?"

"It seems to be Cui Yufen, I don't remember exactly, but when we were in the fifth grade, this sister was in the fourth grade, and she should be two years younger than us and started school early."
