Chapter 309
After Zhu Yufen left, Xu Dayuan came to the observation room next door, looked at Zhou Ning and sighed.

"This person is miserable enough. The whole family ran away from home, some ran away from home, some died, and they were clean enough."

Liu Yongxin crossed his arms, wondering what he was thinking, seeing Xu Dayuan looking at him, he opened his mouth and said:
"Aunt Zhu Yufen's son died of leukemia in [-], and she committed suicide on New Year's Day in [-]. Not long after, Zhu Kelin brought back a son who was less than one year old. Let someone verify the date of birth.

How do I feel that this son came at the right time, nine months pregnant and less than one year old, didn't he have an affair when Zhu Kelin's son discovered leukemia? "

Xu Dayuan nodded, took out his mobile phone, and just about to dial, a call came in, it was a number in Shanghai, and he quickly connected it.

"Old Huang, have you checked for me?"

"You boy, you still have such a temper. Wait for the picture to be sent to you later. What I want to tell you is that you asked me to check this person. I asked the doctor casually. His physical condition is very bad. He said it was liver cancer, but Further examination revealed that there was also a tumor in the lung."

"Transfer?"

"Wait, let me read the diagnosis to you. Patient Ai Qingsong's right lung adenocarcinoma is stage IV, with multiple metastases throughout the body, pericardial effusion, superior vena cava syndrome pleural effusion, multiple liver lesions, portal vein thrombosis, Consistent with liver Ca manifestations, some portal vein Ca thrombus formation may be large.

The doctor said that Ai Qingsong actively cooperated with the treatment and hoped to have surgery, but after their analysis, the indications for surgery were insufficient, and it would be very difficult to get off the job. If treated conservatively, the survival period is about 0.5-1 year.

Anyway, from what I heard, it means that Ai Qingsong was originally planned to have surgery, but after consultation, the surgery plan was canceled, and he is discussing with him to carry out chemotherapy and radiofrequency ablation to improve the quality of life in the final survival period, basically It's a death sentence. "

Xu Dayuan connected through hands-free, while Zhou Ning and Liu Yongxin were listening on the side. Zhou Ning had heard Ai Qingsong's voice during the previous call. Although he was weak, he was still very active in the treatment.

"I see. Are his fingers clubbed? Did you ask his doctor when you took the picture?"

"Well, I asked the doctor that Ai Qingsong's right hand except for the thumb, the remaining four fingers are standard clubbing. He asked me why I should ask this carefully, but I was prevaricated. I said this person is not a suspect, right? "

Xu Dayuan coughed.

"It's really a suspect, but there is no further investigation. Lao Huang, help me send someone to watch Ai Qingsong. The plainclothes will follow. Ask the doctor for some blood samples. Send me the DNA test results. I need someone to compare. right.

When my person arrives, he will take over the job, but during this period of time, don't let him leave the hospital or contact the outside world, the doctor will explain. "

"There is only so much suspicion. This is a lack of evidence. What case is it convenient to say?"

"I'll send you a letter of investigation later. A serial murder case that lasted 19 years. We only found fingerprints of clubbed gloves in two of the scenes. The others are still under investigation."

The other party didn't say anything else. Everyone in the industry knows how difficult it is to span such a long period of time.

"Sure, I'll send someone to watch it first, and then explain to the doctor, I'll call you if I don't leave, or I'll have to make a second trip."

"Don't talk nonsense, when you explain things, I will do my best to help, right? Since you went to the hospital and talked with the doctor, you always know whether Ai Qingsong has family members to take care of you?"

The person on the opposite side said to wait a moment, and then there was a sound of footsteps and knocking on the door, he went directly to the attending doctor, and asked the doctor Xu Dayuan's question.

"He came to see the doctor alone. He was not accompanied by his family members. He was taken care of by a nurse. He introduced all the diagnoses and films very clearly, so we did not hide his condition. The cost is also very high.

He took the initiative to say that there is no need to save him financially. He has money. We didn’t ask about other things. There is usually a nurse to take care of him. He also mentioned that he doesn’t sleep well and hopes to live in a single room. "

After thanking him, Xu Dayuan hung up the phone and called Tao Zhenshan to give instructions.

After finishing the order here, Zhou Ning's cell phone rang.

"Hey Big Zhao."

Zhao Xinli's excited voice rang from the phone.

"Zhou Xiaozhou, we found the skull. Go back now, and we will be there in about 20 minutes. You can wait for me in the forensic room."

After he hung up the phone, Xu Dayuan rubbed his nose and laughed.

"Has this kid been kicked out by a dog? He was in a hurry, and hung up the phone after yelling, and he didn't know what to say."

Liu Yongxin glanced at Xu Dayuan, moved his lips, and swallowed back what he was about to say, Zhou Ning almost didn't laugh out of that look, he quickly lowered his head, and was chased by the dog, it's not like you're urging him every day.

"The skull was found so quickly. Don't think too much, it must have been found in front of Cui Yushang's grave. It seems that our previous analysis is correct, but we will scan the skull later and compare the photos of the three deceased to confirm the identity of the three. "

Xu Dayuan hummed and scratched his hair.

"My mind is a little confused now. According to the clubbing finger you mentioned, Ai Qingsong is the most suspect. It depends on who he has contact with. But the current investigation on Li Hua and Zhu Yufen is limited to their narration. It seems These two want to find out who has intersected with Ai Qingsong?"

Liu Yongxin didn't speak, and looked at Xu Dayuan with folded arms.

"This is your business. My apprentice and I are just waiting for the skull to come back."

Zhou Ning sighed.

"Let me lend you Xiaoqu and let him cooperate with your investigation. As for the homes of Li Hua and Zhu Yufen, can you apply for a search?"

17:44
The forensic room of the Criminal Police Team of Hai'an City.

Dazhao Zhangluo said, and asked people to put several sorting boxes on the dissecting table. Yang Xuetong opened the first box, then held up the camera to show the photos on it, and said:

"When we arrived at the scene, the local investigators called people from the village committee. After identification, we found Cui Yushang's grave. The tombstone is very simple, just these words, the tomb of the eldest son Cui Yushang, October 1979, 10."

Zhu Xingxing was at the side and searched for the date on Baidu.

"October 1979, 10 was a Saturday, which is consistent with what Ai Qingsong said earlier."

"Where was the skull found?"

Da Zhao has already walked to Zhou Ning's side, pointing at Yang Xuetong's camera, they took a panoramic picture, and gestured around the tombstone.

"We dug a circle around the cover of the grave, and the three skulls were neatly arranged behind the tombstone. We didn't dig very deep. Each skull was packed in a wooden box. The size, style, and newness of the boxes were different. It was done in three installments."

Zhou Ning nodded, and looked up at several sorting boxes. There were wooden boxes inside the boxes, but there was still a lot of soil around them, which made Zhou Ning a little puzzled.

"Hurry up and finish what you find. Is there anything else in the soil?"

Da Zhao bared his teeth and grinned, bumping into Yang Xuetong.

"What did I say? Zhou Xiaozhou is now infected by Bureau Xu, and he is also impatient. Don't worry, I'm not talking about it. We found three wooden boxes, so we expanded the excavation area and found them in a deeper place under the boxes. Something, three axes.

However, the sky was a little dark, so I was afraid that I might miss something, so I hurriedly asked someone to dig out all the soil near the axe, thinking about coming back and sifting it carefully. After killing them, the heads of the three people were also sacrificed. Why did they keep the axe? "

Liu Yongxin came over, took a look and said:

"I took over a case back then. The murderer also buried the murder weapon and the deceased in his father's grave. The murdered person killed his father back then. This is a special kind of revenge mentality."

Zhou Ning nodded. He had seen similar cases in the book written by Li Chengbin, where some of the deceased's stumps and murder weapons were placed in the cemetery that needed to be sacrificed.

"Okay, it's useless to analyze too much, quickly take out the three wooden boxes first, then extract the fingerprints or residues on the surface of the boxes, and finally collect the DNA on the skull, Xiao Qu went to cooperate with Xu Bureau's investigation, the skull scan Zhu Xingxing Do it, can you?"

Zhu Xingxing nodded.

"I'm with the high-speed rail, we have seen it many times, and the scan is absolutely fine."

After speaking, several people started to move.

Da Zhao and Yang Xuetong started to sieve the soil. Three axes were placed on one side, and the broken stones and some rope ends were sifted out from the remaining soil.

As for the wooden boxes inside the three sorting boxes, they were carried out by Zhu Xingxing and Sun Gaotie and placed on the dissection table. Afterwards, they began to take pictures and samples. As the boxes were disassembled and the scans were completed, Zhou Ning walked up to them.

The skulls in the three wooden boxes have collapses and defects on the top of the head, temporal part, and occipital part respectively. The shape of the cut and bruise is very clear, which completely conforms to the shape of the ax blade and the square beating surface.

Zhou Ning and Liu Yongxin checked it again. The thyroid cartilage and hyoid bone of the three skulls were well preserved, and the hair was also at the bottom of the wooden box. The more Zhou Ning looked at him, the more puzzled he was. Zheng Chuguang and Zhou Ning had always suspected that he died of suffocation. Zhou Ning has no objection.

Yu Guangyao drowned in the bathtub, Zhang Qiujian was probably mechanically suffocated by the down jacket, but was the slash on the head to vent his anger after death, or knocked the dead unconscious to prepare for the next murder?
For a while, Zhou Ning was also a little confused. When he looked up, he found that Xiao Qu had returned at some time, and had already started the software comparison. He turned his head to look at the big screen.

Above are the photos of the three deceased, of course, they are all photos near the time of death. As the comparison frame flickers, there are reconstruction pictures of several skulls corresponding to the photos of the three of them in a moment.

Da Zhao quickly put labels on the wooden boxes and pallets under the skulls.

"Okay, it's finally time to figure out who is who."

Zhou Ning walked up to Zheng Chuguang's skull, took it out carefully, and examined the bottom carefully. The hyoid bone was broken, but the thyroid cartilage was not found. However, the deceased had been dead for 19 years, which is not surprising.

Seeing this, Zhou Ning closed his eyes. The deceased seemed to be standing in front of Zhou Ning. At first, the murderer hit his temple with an ax while standing. The deceased fell to the ground and hit the back of his head heavily. Zhou Ning shook his head.

wrong.
