The autopsy continued. Except for this piece of leather-like substance, nothing else was found in the intestinal tract, but several pieces of coagulated and shriveled blood clots were found. When it was opened, the intestinal tract was obviously damaged.

All this shows that the deceased had been starving for a long time, causing erosive damage to the gastrointestinal tract, and even bleeding. As for the piece of leather-like substance, it was mainly too large to bite into, so it got stuck in the duodenal bulb, where it was supposed to be. There are ulcers, and they remain there until death.

Shaking his head, the rectum of the deceased has been checked at this time. There are many strips of damage here, but it is different from the ulcer erosion in the stomach and small intestine. It seems to be a scratch. The scratch is irregular and very slender, not caused by nails. .

Thinking of those leather-like substances, Zhou Ning didn't pay much attention to them. It's not surprising that such hard things will cause damage to the intestines, especially the rectum, which needs excretion and peristalsis. If there are hard horns, it is easy to cause scratches.

After finishing the dissection of the chest and abdomen, Zhou Ning shook his sore neck and waved his hand directly to signal Zhu Xingxing to go over.

"Get ready, you continue to do the craniotomy, avoiding the fractures of the deceased, and show me after opening, if there is any concussion injury."

Zhu Xingxing held back his excitement and dragged the two interns to prepare things.

In fact, after more than two months of training, these two people are not a little bit more capable than the interns in other groups. There is no panic or tension. They are calm, calm, and methodical. They have learned the essence of Zhou Ning.

Liu Yongxin glanced at it and nodded in satisfaction, not to mention that his apprentice is really good at teaching students.

Zhou Ning walked to the left side of the deceased at this time. Liu Xiangrui, the first deceased, had a defect in his right hand. It seemed that the damage was caused by animal bites, and there was no corruption. not long ago.

Pulling a chair with wheels over, Zhou Ning sat down, pulled over the LED magnifying glass, and carefully observed the nails on the left hand of deceased No. [-]. The left hand of the deceased was not like other parts of the body. I guess it has something to do with the action.

The fingers and nails of the deceased were dark brown. There was a broken mark on the nail of the little finger, and there was a defect on the nail bed. The edge of the broken mark was irregular, and there was a blood scab on the nail bed.

Zhou Ning blinked. Usually, when he grabbed something or accidentally broke his nails, they would usually be broken neatly. Even if they were not neatly, they would be broken along the edge of the nail. It was rare for him to break it obliquely in the middle.

Flipping his fingers, he found that the pulp of the little finger seemed to be a little swollen, and it vaguely felt that there seemed to be an E-shaped mark lying down. This discovery moved Zhou Ning's heart.

He hurriedly dragged the magnifying glass closer, but the more he magnified, the more he couldn't tell whether it was tooth marks or not. However, Zhou Ning directly asked for pliers and a sampling knife, and cut across the nail bed to separate and remove the nails.

Seeing this, Da Zhao shivered, but he gritted his teeth and didn't make a sound.

Zhou Ning glanced at him, Da Zhao pretended to be okay and avoided his eyes, Zhou Ning glanced at Zhu Xingxing's side, they were all over, Sun Gaotie had come back at this time, he waved at Sun Gaotie.

Sun Gaotie didn't know why, so he ran to Zhou Ning excitedly.

"What's wrong?"

"Come on, you take over the sampling from me, take off all the nails of the deceased, mark which hand is clear, and prepare to send it for inspection."

"Oh ah?"

Sun Gaotie was shocked, he looked at Zhou Ning and then at the dissecting table, Liu Yongxin looked at Sun Gaotie, and glanced at the two interns beside Zhu Xingxing, Sun Gaotie swallowed all the words he was about to rush out, and hurriedly Putting on the gloves, he stood at the position where Zhou Ning had just stood, and began to tremblingly handle his nails.

Zhou Ning's mind is in a mess now, because all the existing discoveries are showing that the deceased died of long-term starvation, except for the fracture of the head. Only one was caused when the deceased was on the verge of death.

Then, why was a person who was starved for five days and immediately lost his breath, being hit on the head one after another?
Putting away the thoughts in his mind, Zhou Ning walked in front of Zhu Xingxing, where the craniotomy had been completed, and the two interns were cooperating with Zhu Xingxing to lift the skull of the deceased. The two looked clumsy, and they were about to kneel at this time , sweat all over his face.

In fact, Zhou Ning did it on purpose. They have seen dismembered corpses before, or the dismembered corpses in the high-rotten state of the giant view, and the bones salvaged from the septic tank. With such a high-density stimulation, you won't feel overly stimulated by any dissection afterwards.

Zhu Xingxing cut off the connecting part, and the two were relieved. They lifted the tray and quickly made room for Zhou Ning.

Glancing at the inside of the skull, the brain tissue was curled up into a ball, with clear folds on it, and there was no bloody staining on the forehead, skull base, sphenoid sinus and other parts, let alone contusion injuries.

Gently separate the mass of brain tissue, Zhou Ning lifted it up, and observed it around. Only the brain tissue corresponding to the top of the skull had traces of bloody secretions, but the amount was very small, just a plaque the size of a soybean. is also like this.

Zhou Ning let out a long breath, put the brain tissue back, and waved at Zhu Xingxing.

"Let's sew it up, reorganize the various samples, and send them all for inspection."

Zhu Xingxing turned off the video and hurriedly stopped Zhou Ning.

"Boss, tell us quickly. The deceased's intracranial injury is not serious. Except for the palm, there is no fatal trauma on his body. The hyoid bone and thyroid cartilage are intact. Dried foam from drowning.

The lungs are also in a normal and dry state. The heart, liver, spleen, kidneys, bladder, all the organs we can check are checked again. Except for some ulcers and erosions in the digestive tract, there is nothing useful to find at all. What is the cause of this person's death? What? "

Everyone looked at Zhou Ning. Zhou Ning pulled off his mask and glanced at the film of the deceased on the big screen.

"That's right, he didn't have any disease, the wounds from four blows on the top of his head were either in a near-death state, or the injuries caused by the blows after death. As for the fatal injuries, I think it was starvation, and this person died of starvation.

In the late stage of long-term starvation, energy intake is insufficient, autologous fat and protein metabolites accumulate in the body, azotemia and acid-base balance disorder occur, and vital organs that maintain normal life activities malfunction, resulting in death.

Of course, the deceased also showed signs of severe dehydration, that is to say, he was not only starved, but also starved in a place without water. This reminded me of the people trapped after the earthquake, but their activities were limited, and he There are no restraints on my body, which I can't understand. "

After Zhou Ning finished speaking, everyone in the autopsy room was silent, not because it was obscure, but because he felt that the death of the number one deceased was too miserable, he was starved to death, and was beaten on the head when he was about to die. The exposed corpse in the wilderness turned into a mummy in the end, what kind of grudge is this?
In silence, the door of the dissection room was opened.

Xu Dayuan and Liu Yufei walked in, seeing the serious expressions on their faces, Xu Dayuan hurried to Zhou Ning's side.

"Why, didn't the autopsy go well?"

Zhou Ning shook his head.

"On the contrary, the autopsy went smoothly, and the cause of death has been found, but the test needs to wait for the final result."

Having said that, Xu Dayuan was even more puzzled, glanced at the dissecting table that was being sorted out, and hurriedly asked:
"What was the cause of death?"

"To be precise, Liu Xiangrui, the first deceased, died of starvation. As for the blow injury to the head, it was caused after death, perhaps out of venting anger. They waited quietly to starve to death, and did not resist or struggle."

As he spoke, Zhou Ning showed Xu Dayuan the details, and repeated what he said just now. After hearing all this, Xu Dayuan was also stunned.

Liu Yufei leaned over and glanced at the deceased.

"The names of these two dead people are so auspicious and have meanings. I didn't expect that they died so badly."

Zhou Ning nodded, motioned Zou Jialong to send the corpse away quickly, took Xu Dayuan and the others back to the office directly, Zhu Xingxing had already started sorting out the findings in the autopsy, writing quickly on the other side of the whiteboard, Zhou Ning glanced, sat In front of Xu Dayuan.

Before Zhou Ning could speak, Xiao Qu's computer beeped, Zhou Ning got up and walked over, took a closer look, and the printer next to him was also busy.

After reading the content, Zhou Ning's brows did not stretch too much.

"The report of the second deceased, Zhang Wannian, came out. An unknown male's DNA was found on his coat and dagger, but no match was found in the database. It was found in various organ samples that Zhang Wannian's liver cancer had metastasized to the lungs."

Liu Yongxin leaned over with a look of difference.

"So accurate, the part of the lung that was sent for examination is the cancer focus?"

Zhou Ning nodded.

"It was quite lucky, but there was another unexpected situation. The new analyst did an extra test and found that Zhang Wannian was actually an HIV carrier."

"AIDS?"

Shocked, Xu Dayuan looked sideways at Liu Yufei.

"You went to the hospital to check Zhang Wannian's medical records, have you seen the doctor?"

Liu Yufei nodded, and took out a large stack of photocopies, and at a glance, she knew it was the medical records of hospitalization for surgery.

"I checked, but I couldn't understand it, so I brought it here to show Director Zhou, but I didn't hear the doctor say that Zhang Wannian is an AIDS patient?

I introduced his liver cancer and postoperative chemotherapy. I also went to the central hospital to find Dr. Chen and asked him to take a look. He said that the recovery of this man was not good.

The last examination was on September 9, and he was asked to do further examinations, but there was no follow-up information. I checked all the major hospitals in Qindao, but I couldn't find Zhang Wannian's medical records. "

Da Zhao coughed, as if he heard that Liu Yufei was looking for Dr. Chen to find out the situation, with a gossip look on his face.

Zhou Ning glanced at him sideways, he suddenly got stuck, but seeing that everyone was looking at him because of the cough just now, he blinked and changed the subject quickly.

"Then Bureau Xu, I just want to ask, does Dayao City need me to contact you?"
