Chapter 4: Big Brother, guess the riddle?
Oh my god, am I so lucky?
Zhou Ning bent down excitedly and got closer to observe the school badge carefully.
There were bloodstains on the badge, but the four words "Qidong Medical School" were particularly eye-catching.
After finding this, the identity of the deceased would be easy to check. Zhou Ning quickly wiped the blood and took a close-up of the school badge and the deceased's face.
He turned around and knocked on the door, and the auxiliary police officer Xiao Liu who was waiting outside poked his head in.
"What's wrong, Xiao Forensic Doctor Zhou?"
"Xiao Liu, do you have a police pass? I need to send the photo of the deceased to Xu Da."
Xiao Liu nodded quickly and took out a very advanced-looking mobile phone from his pocket.
Zhou Ning took it without further ado, walked to the old computer in the autopsy room, turned the photo over, searched for Xu Da directly on it, and clicked send.
Then he dialed Xu Da's cell phone number. After it rang, the other party picked up immediately.
"Did Xiao Zhou, the forensic doctor, find anything?"
Zhou Ning swallowed his saliva, suppressed his excitement, and tried to speak calmly:
"Master Xu, I borrowed Xiao Liu's police communication system and sent you two photos. One is the face of the deceased, and the other is the school badge found on the deceased. I suspect the deceased is a student of Qidong Medical School. Use the photos to try to find him."
Xu Dayuan laughed twice.
"Haha, fine, I'll go find the school right away to identify it."
After hanging up the phone, Zhou Ning breathed a sigh of relief and returned the police communication card to Xiao Liu. The boy ran out without saying a word. Seeing his cowardly look, Zhou Ning suddenly felt that he was not bad.
After hanging up the phone, Zhou Ning put on a disposable isolation suit, a hat, a mask and latex gloves. Zhou Ning picked up the splint with a printed picture of the autopsy record on it.
At this time, the deceased's information had not been confirmed yet, so Zhou Ning did not rush to move. He just held the splint and closed his eyes slightly.
I just said I received a reward, but my mind is full of the framework of forensic evidence, such as blood drop identification, injury object inference, electronic evidence investigation, forensic scene analysis and reconstruction, on-site inspection of arson cases, dismemberment cases and unidentified corpse cases.
All kinds of detailed knowledge, even various on-site pictures, appeared in Zhou Ning's mind all at once, flashing like a movie. The knowledge was very detailed, and there were targeted explanations of the case, as if it had originally belonged to his memory.
I didn't have a splitting headache this time. I guess it's because it's not a cramming-style indoctrination, so it won't give me a headache.
Zhou Ning browsed through it carefully, and this time it was clearer than when he just got the forensic on-site training.
After an unknown amount of time, Zhou Ning opened his eyes and pushed up his glasses.
The image of the corpse and the various known information next to it remained unchanged, except for one more sentence next to the corpse's portrait.
Suspicion: Is the deceased a student of Qidong Medical School?
As for the system, it was also quite quiet, with no prompts for new tasks. It seemed that when he made some discoveries during the autopsy, the system summarized them, and he needed to make these discoveries on his own. If he stagnated, the system prompts would not be triggered.
Just like in the Novice Village, you can’t leave the Novice Village at all unless you find the NPC at the entrance of the village to trigger the task.
After figuring this out, Zhou Ning no longer acted like a headless fly. Since he was waiting for a call, he might as well just sit there and wait.
After finding the ink, Zhou Ning began to collect fingerprints, then measured the rectal temperature and asked Xiao Liu to find someone to take an X-ray of the deceased. This equipment was available in the autopsy room, but he did not know how to use it.
After half an hour of hard work, Zhou Ning recorded the rigor mortis of the deceased's joints, held up the splint to record all the data, and called forensic doctor Liu again.
"Master, let me report to you. I measured the deceased's rectal temperature and it was 32.1 degrees. According to the formula 37 degrees - corpse rectal temperature / 0.83 * coefficient, I inferred that the deceased's time of death [1] was 8.27 hours ago.
The time I measured was 10:50 in the morning, which means the deceased died at 2:23 in the morning. Only the small joints of the jaw and fingers showed rigor mortis, which is consistent with the rectal temperature. Master, how should I write this death time report?"
Forensic Doctor Liu on the opposite side hissed, and it was not known whether he had touched the wound.
"Xiao Zhou, your calculation is correct. The temperature here is high, so we should use the summer coefficient. However, we only need a range for the time of death of Xu Da and his men. We can report to Xu Da that the time of death is between 2:00 and 3:00 on September 27. Have you found the identity of the deceased?"
"I didn't find it, but I found the medical school badge on the body of the deceased. Xu Da and his team have already checked it out."
"Then there's no need to rush. You've done a very detailed job. Wait a moment. I'll finish the IV and go to the autopsy room to take a look."
After hearing what Forensic Doctor Liu said, Zhou Ning felt relieved and hung up the phone.
As soon as he hung up, Xu Dayuan's number flashed on his phone and Zhou Ning quickly answered it.
"Xiao Zhou, forensic doctor, please stay in the autopsy room. I will take the family of the deceased to identify the body. Please prepare the autopsy consent form."
"OK."
In the huge autopsy room, Zhou Ning rummaged on the table next to the computer and finally found a consent form. Just as he was getting ready, the door of the autopsy room was pushed open.
Xu Dayuan walked in with a man and a woman, followed by a female police officer of aunt level. Looking at the nervous expressions of the two, one could tell that they were direct relatives.
In fact, you can determine whether it is the deceased through the photo, and taking a look is also to end the last thought.
After all, as the old saying goes, if someone is alive, I want to see him/her, and if he/she is dead, I want to see his/her body.
Xiao Liu closed the door, stopped the two and distributed masks to them. Zhou Ning went over with the consent form and stood between the dissection table and the family members.
Xu Dayuan nodded to Zhou Ning and tried to make his voice gentler.
"Come closer and take a look. Is it your Xiao Maner?"
The two men took a closer look. The man was fine, but the woman's legs went weak and she collapsed to the ground. Her crying and screaming filled the autopsy room.
Xu Dayuan breathed a sigh of relief. This expression was self-evident, but the necessary procedures had to be followed.
"You two should control your emotions. We still have a lot of things to discuss with you. The child is gone, we can't just leave it like that. Finding the murderer is the most important thing. Come and sign the consent form first, and we'll go out and talk in detail."
As he spoke, he raised his chin towards the policewoman, who helped the woman out. The man took the tissue Zhou Ning handed over and wiped his tears, then looked at the autopsy consent form Zhou Ning gave him.
Obviously, the man paused.
Xu Dayuan seemed to be very familiar with this situation and said to himself:
"In fact, according to the procedure, for criminal cases, we can directly perform an autopsy without the family's consent. However, because the identity of the deceased is unknown, we still want to wait for you to take a look before doing it. It will take time, and the longer the delay, the smaller the chance of catching the murderer, right?"
The man nodded, and without further ado from Xu Dayuan, he took the autopsy consent form from Zhou Ning and signed it directly. Then he looked at Zhou Ning and Xu Dayuan and bowed 90 degrees.
"My little Man'er passed away so suddenly. I beg Officer Xu to do his best to solve the case and catch the murderer as soon as possible."
Xu Dayuan nodded, patted the man's shoulder, pointed at Zhou Ning and said:
"Brother, everyone of us has children at our age. I understand how you feel. I hate to see a murderer like this go unpunished. See ? This is our new top student. He was the one who found out your little Man'er's identity. We have professionals who will do their best to solve the case. Come on and talk to our police officers and provide some information."
As he said that, Xu Dayuan took the man out. Zhou Ning blinked. He never expected that he would be promoted as a celebrity one day.
After a while, Xu Dayuan came back quickly.
The look in Zhou Ning's eyes was completely different. He took off his hat and wiped the sweat off his forehead.
"Xiao Zhou is great. He is very observant. I thought it would take some effort to check the identity, but I didn't expect that you could find it anywhere. Please record it here as well."
As he spoke, he handed Zhou Ning a piece of paper with a photo of a girl on it. She had a bright smile, long flowing hair, and a light yellow dress, all of which exuded a youthful vibe. He knew that this was a photo of the deceased. In fact, it was difficult to connect them together, after all, the deceased's face had been deformed.
"The deceased is Su Manli, 17 years old, a third-year student of the 3+4 nursing program. She is not a good student and is a bit rebellious. She lives in an apartment near the school. Her father runs a Volkswagen 4S store and does not live in the city to take care of the business.
The school visited her and learned that she changed boyfriends frequently. She was either skipping classes or going out singing and drinking with guys outside the school. She was criticized every now and then, but the teacher always said good things about her. It seemed that she was spoiled by her father.
All along the way, his father kept saying that he suspected someone was taking revenge on him and harmed the child, and asked us to quickly investigate his competitors. Okay, now that I've explained the general situation, do you understand what more should be investigated during the autopsy?"
Zhou Ning was stunned. Is elder brother guessing a riddle?
I'm such a simple person, how do I know what you want to express? Can't you just say it directly?
…
PS:
【1】Calculation of time of death: According to a domestic corpse temperature research report, within 4-5 hours after death, the body's heat generation has not completely stopped, and the body temperature drops by an average of 0.58 degrees per hour; 5-16 hours after death, heat generation completely stops, and the body temperature drops by an average of 0.97 degrees per hour; 16-24 hours after death, the temperature difference between the body and the environment decreases, and the body temperature drops more slowly, dropping by an average of 0.54 degrees per hour. This study established a formula for calculating the time of death, and after practical application and improvement, the following simple formula was obtained:
Time since death (hours) = 37 degrees - rectal temperature of corpse / 0.83 * coefficient
(The multiplication factor is 1 in spring and autumn, 1.4 in summer, and 0.7 in winter.)
