Chapter 18: One-third Palm Print
"Come on, get to work."
Zhou Ning's resistance was futile. He sighed, suppressed his nausea, and began to clean up.
In fact, as long as you get started, the cleaning process is very fast. It was completed in just over ten minutes. Zhou Ning put the lid on the glass jar and threw it on the lower level of the stainless steel cart next to him. He felt a little more comfortable.
This time, Forensic Doctor Liu did not let Zhou Ning do it, but started the autopsy himself. He knelt on a chair with his leg in a cast and quickly performed the autopsy according to the steps. At the same time, he kept asking Zhou Ning to record the relevant autopsy content and take samples.
The deceased, Li Delin, had seven stab wounds on his body. The stab wound on his neck cut his carotid artery, but the cut was not big. The five stab wounds in his lower abdomen did not damage any important organs. The stab wound in his back directly pierced his heart, which was a fatal injury.
After removing the white glove-like skin from both hands, multiple cuts can be seen, and the index finger of the right hand is almost completely broken, which is obviously a resistance injury.
The murder weapon was an ordinary stainless steel pointed machete, the brand was Zhang Xiaochu, it had no guard and the handle was also made of stainless steel.
Zhou Ning measured it and found that the tip angle of the knife was 75°, the total length of the blade was 26 cm, and the blade was 14.5 cm long. A piece of dried cucumber slice was stuck to the very end of the handle. Although it was only the size of a grain of rice, it was recognizable. It was obviously made from local materials.
Li Delin's stomach was also empty, Zhou Ning quickly said:
"When the deceased was found, there was vomit next to the pool of blood. I estimated that it was about 500ml. I have already taken a sample."
Forensic Doctor Liu nodded with satisfaction.
"Well done, did you measure the size of the little maggots and pupae at that time?"
"Yes, based on this, I inferred the time of death. Oh, by the way, I found a shopping receipt from Liqun Supermarket in the pocket of the deceased's pants. There was a complete range of meat, eggs and vegetables in it, and the quantity was not small. The date was October 18th.
However, the refrigerator in the home of the deceased female, Zhu Meifeng, was empty, and no packaging bags or anything like that were found in the trash can. "
Forensic Doctor Liu raised his head and glanced at Zhou Ning.
"Show me the vomit sample and the photo of the receipt."
Zhou Ning tore off a layer of latex gloves, found the photo on the camera, and held it in front of Forensic Doctor Liu, who tilted his head back.
"Kid, don't you know that people get blurry-eyed when they get old? What can I see when I'm so close? Oh, the things you bought are all high-end goods, such as Tomahawk steak and avocado. Are you going to eat Western food?"
Zhou Ning nodded, and he agreed with this judgment.
"Yeah, I think so too. I can't tell the difference between vomit and vomit. It's all dried up after all."
Forensic Doctor Liu glanced at the sample, shook his head and continued:
"Looking at the presence of carrots and meat, we can tell by sending it for inspection. Okay, the autopsy is complete. Mark it. The fetus of the deceased female will be compared with the DNA of the deceased male."
Zhou Ning paused.
"Master, do you suspect that Zhu Meifeng's child is Li Delin's?"
Forensic Doctor Liu nodded, but did not stop suturing until he tied the last knot.
"Well, to use the words of you young people, this is called the sixth sense. It's right to do one more test. We can't do the DNA test here. We have to send it to the city's testing center. The speed is very slow. Let Xu Da rush it. The earliest result will be available tomorrow afternoon.
The knife handle will be fingerprinted first, and then sent for inspection. This will be marked to check whether the substance collected from the knife is consistent with the stomach contents of the male deceased. In this way, it can be determined that the knife was obtained by the murderer at the deceased's home."
Hearing this, Zhou Ning was numb.
Subconsciously, I glanced at the large transparent screen. The countdown had jumped to 59:49. Twelve hours had passed before they completed the autopsy. The test results would be out as early as tomorrow afternoon. Wouldn't there be even less time left?
The second question of the intermediate task is to find the murderer and all the evidence.
What we need is all the evidence. Isn't this going to be a disaster?
Forensic Doctor Liu sat on a chair and kicked Zhou Ning's shoes with his uninjured foot.
"What are you thinking? Are you starving? Hurry up and ask someone to collect the body. Do you think the stench is not strong enough?"
Zhou Ning said "oh" and quickly ran to the door and kicked it open. Zhao Xinli and the others who were squatting in the corridor quickly stood up.
"Is it over?"
"The autopsy is over. Hurry up and call a few guys to help take the body to the morgue."
Zhao Xinli brought people in, and everyone, except for forensic doctor Liu, helped to move the body onto a flatbed cart and send it away.
Zhou Ning returned to the workbench and collected fingerprints on the knife handle. After a long time, he extracted two complete fingerprints. Most of them were fingerprints from the thread gloves, but next to the traces of the thread gloves, there was also a third of a palm print.
This discovery made Zhou Ning pause and he looked up at Forensic Doctor Liu.
"Master, we found two fingerprints and a palm print on the knife, and more traces of glove marks. You said there was no hand guard on the knife handle. The victim had resistance wounds despite such a violent stabbing. Does that mean the murderer's hand might have been injured as well?"
Forensic Doctor Liu had already taken off his heavy isolation suit, his hair completely stuck to his forehead, and he smiled while wiping the sweat off his face.
"No wonder Xu Da likes you. It's rare to have such a keen mind. Your analysis is very reliable. The murderer's right hand may be injured. Let's wait for the final test results. If we are lucky, we can extract the murderer's blood from the knife."
Zhou Ning knew that if he could find the murderer's blood, it would be no different from winning five million.
But it's good that there is a wound, at least it can narrow the search range for the suspect.
"Don't just stand there, call Xu Da, he's waiting for the autopsy results."
Zhou Ning dialed Xu Dayuan's cell phone. After one ring, the call was connected.
"Is the autopsy finished?"
"Well, Mr. Xu, shall we report the autopsy results to you now?"
The countdown was urging him, and he was more anxious than Xu Dayuan and the others. There was no need to hide it at the moment, so Zhou Ning expressed his thoughts eagerly.
"Ha, you are even more impatient. Let Zhao Xinli and the others take you back. We are in the team."
Forensic Doctor Liu washed his hands, wiped the sweat from his face, and waved at Zhou Ning.
"Bring the autopsy records with you. Just listen to the special case meeting. Bring the samples and the murder weapon with you. When you get there, tell me about sending them for inspection first. This can't wait. I'm going back now. I've been standing for nine hours and my legs are numb."
Zhou Ning did not try to persuade him to stay. He was already very grateful to Forensic Doctor Liu for coming along today and taking the initiative to examine this highly decomposed corpse. It was a rare master who was considering newcomers so much, as he was a man who had retired in half a year.
"Thank you, Master. I will go with them now, but how are you going to get back?"
Forensic Doctor Liu waved his hand.
"Just take a taxi and leave. Don't worry about these trivial matters. Let's go quickly. Xu is impatient. If you get married one day and want to be a father the next day, you should keep up with his pace to avoid being scolded, okay?"
"Well, I'm leaving now!"
Zhou Ning cleaned himself up quickly, packed all the evidence bags into boxes, took the two autopsy records and the camera, and walked out the door.
Zhao Xinli answered the phone at the door and saw Zhou Ning waving his hand.
"...Okay, boss, don't worry, we will rush back to the team immediately."
Several people got in the car and drove towards the criminal police team.
Forensic Doctor Liu limped out of the autopsy room. The old man from the morgue came over, took the pack of cigarettes handed to him by Forensic Doctor Liu, took out one, and put the rest in his pocket very naturally. The two of them lit up and started chatting while puffing smoke.
"This young man looks good, but your leg is fine now, why is it in a cast again?"
Forensic Doctor Liu glared.
"If you don't whip me, or put on a cast, I'll have to go to the scene with you today. How can I train him that way? The difference between learning in theory and actually doing it is huge. The apprentice I had before was also very capable, but he ran away in less than two months, so I'm going to use some tricks this time."
Old man Cui smiled, shook his head, and walked towards the morgue humming a Mao tune.
…
October 27, 21:37
Qidong County Criminal Police Team Conference Room.
As soon as Zhou Ning opened the door, Xu Dayuan and the others looked over, and when they saw the box in Zhou Ning's hand, they quickly waved their hands.
"Chun Yang, quickly send someone to deliver the samples to the city's forensic laboratory. I called and they kept someone to work overtime for us."
Zhou Ning let out a breath, put a list he had written on the way on the box, and handed them to He Chunyang.
"Captain He, this is the detailed list of what needs to be tested, corresponding to the sample number. There is one that requires DNA comparison, which needs to be done first. It is best to keep someone waiting for the test results and email it to me as soon as possible."
He Chunyang smiled and nodded, took the box and arranged it. Xu Dayuan waved his hand and motioned Zhou Ning to sit down.
"Sit down and tell me the results of your autopsy. There is no change in the estimated time of death of the deceased, right?"
