Chapter 4 Where is the big brother guessing the riddle?

Let me go, are you so lucky?

Zhou Ning bent down excitedly and looked closely at the school badge.

There are blood stains on the badge, but the words Qidong Medical School are particularly conspicuous.

After finding this, it was easy to check the identity of the deceased. Zhou Ning quickly wiped the blood stains clean and took a close-up of the school badge and the face of the deceased.

Turning around and knocking on the door, Xiao Liu, the assistant policeman waiting outside, poked his head in.

"What's wrong, forensic doctor Xiao 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 didn't waste any time. He took it and walked to the old computer in the anatomy room. He turned the photo upside down, searched for Xu Da directly on it, and clicked send.

Then I dialed Xu Da's mobile phone number, it rang once, and the person on the other end answered the call instantly.

"Did forensic doctor Xiao Zhou find anything?"

Zhou Ning swallowed, suppressed his excitement, and tried to say calmly:

"Xu Da, I borrowed Xiao Liu's police pass to send you two photos. One is a photo of the face of the deceased, and the other is the school badge found on the deceased. I suspect that the deceased is a student of Qidong Medical School. Use

Try looking for photos."

Xu Dayuan laughed twice.

"Haha, okay, I'll go find the school to identify it."

After hanging up the phone, Zhou Ning breathed a sigh of relief and returned the police pass to Xiao Liu. The boy ran out without saying a word. Seeing his cowardice, Zhou Ning suddenly felt that he was not bad.

Putting down the phone, Zhou Ning put on a disposable isolation gown, 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 yet been determined, so Zhou Ning did not move in a hurry. He just held the splint and closed his eyes slightly.

I just said that I had received a reward, but my mind was filled with the framework of forensic evidence, such as blood drop identification, injury inference, electronic evidence investigation, forensic scene analysis and reconstruction, on-site inspection of arson cases, dismemberment cases and

On-site investigation of the unknown corpse case.

All kinds of detailed knowledge, and even various on-site pictures, all appeared in Zhou Ning's mind, and the scenes flashed like a movie. The knowledge was very detailed, and there were targeted explanations of the case, as if they originally belonged to his memory.

I don’t have a splitting headache this time. I guess it’s not the kind of cramming, so I won’t have a headache.

Zhou Ning browsed through it carefully. This time it was a little clearer than when he had just received this forensic on-site lesson.

After an unknown amount of time, Zhou Ning opened his eyes and pushed up his glasses.

The picture of the corpse and the various known information next to it remained unchanged, except for an additional sentence next to the corpse's avatar.

Suspect: The deceased was a student of Qidong Health School?

As for the system, it was quite quiet and did not prompt any new tasks. It seemed that during the autopsy, he made some discoveries and summarized them in the system. He needed to obtain these discoveries by himself. If he was stagnant, he would not be able to trigger the system prompts.

Just like in Novice Village, if you don't find the NPC at the entrance of the village to trigger the task, you can't get out of Novice Village at all.

After understanding this, Zhou Ning is no longer like a headless fly. Since he is waiting for a call, don't wait like this.

After finding the ink, Zhou Ning began to collect fingerprints, then measured the rectal temperature, and asked Xiao Liu to find someone to take X-rays of the deceased. This equipment was available in the autopsy room, but he did not know how to use it.

After struggling for half an hour, Zhou Ning recorded the rigor mortis state of various joints of the deceased, held up a 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 to be 32.1 degrees. According to the formula 37 degrees - corpse rectal temperature/0.83* coefficient, I inferred that the deceased's death time [1] was 8.27 hours ago.

The time I measured was 10:50 a.m., which means that the deceased’s time of death was 2:23 in the morning. The deceased only had rigor mortis in small joints such as the mandibular fingers and other small joints, which is consistent with the inference of the rectal temperature. Master, how should I report the time of death?

Write?"

Forensic Doctor Liu opposite him hissed, wondering if he had touched an injury.

"Xiao Zhou, your algorithm is correct. The temperature here is high, so we will calculate it according to the summer coefficient. However, we only need a range for Xu Da and their death time. Just follow Xu Da Bao's inference that the death time is September 27, 2

Between :00 and 3:00, was the identity of the deceased found?"

"I didn't find it, but I found the medical school badge on the deceased. Xu University and the others have already gone to check."

"Then there's no rush. You've done your work very carefully. Just wait a moment. I'll finish the IV and go to the anatomy room for a look."

Hearing what Forensic Doctor Liu said, Zhou Ning felt relieved and immediately hung up the phone.

Just as he hung up, Xu Dayuan's number flashed on his phone, and Zhou Ning quickly connected.

"Forensic Doctor Xiao Zhou, you should be in the autopsy room. I will take the family members of the deceased over to identify him. You should prepare the autopsy consent form."

"OK."

In the huge dissecting room, Zhou Ning rummaged around on the table next to the computer and finally found a consent form. Just as he was getting ready, the door of the dissecting room was pushed open.

Xu Dayuan walked in with a man and a woman, followed by an aunt-level policewoman. Looking at the nervous expressions of the two, you knew that they were immediate family members.

In fact, you can determine whether it is the deceased through photos. Coming to take a look is also to say goodbye to your last thoughts.

After all, as the old saying goes, it’s better to see a person alive than to see a corpse dead.

Xiao Liu closed the door, stopped the two of them, and distributed masks to them. Zhou Ning went over with the consent form and stood between the autopsy table and the family members.

Xu Dayuan nodded towards Zhou Ning, tried to make his voice gentler and said:

"Come closer and see if it's your little Man'er."

The two of them took a closer look and found that the man was okay, but the woman's feet gave way and she collapsed on the ground. The overwhelming sound of crying filled the autopsy room.

Xu Dayuan exhaled. This performance is self-evident, but the procedures that need to be followed still need to be followed.

"Both of you, please control your emotions. We still have many issues to discuss with you. The child is gone, so we can't be so unclear about it, right? The most important thing is that we find the murderer. Come and sign the consent form first, and we'll go out and talk in detail.

.”

He raised his chin at the policewoman, who helped the woman out. The man took the tissue handed by Zhou Ning and wiped his tears before looking at the autopsy consent form Zhou Ning gave him.

It was obvious that the man's movements paused.

Xu Dayuan seemed to understand this situation very well and said to himself:

"Actually, according to the procedure, when it comes to criminal cases, we can do an autopsy directly without the consent of the family. However, because the identity of the deceased is unknown, we still want to wait for you to take a look before doing it. It is already a waste of time. Please delay more time to catch the murderer.

The probability is a little smaller, right?"

The man nodded, and without Xu Dayuan's nonsense, he took the autopsy consent form from Zhou Ning's hand, signed it directly, then looked at Zhou Ning and Xu Dayuan, and bowed ninety degrees.

"My little Man'er's death happened too suddenly. Please ask Officer Xu to do his best to solve the case and catch the murderer as soon as possible."

Xu Dayuan nodded, patted the man on the shoulder, pointed at Zhou Ning and said:

"Brother, everyone at our age has children. I understand how I feel. I hate to see such a murderer go unpunished. Did you see that this is our new top student? He is the one who found out the identity of your little Man'er.

We have professionals and we will do our best to solve the case. Let’s go and talk to our police officers first and provide some information.”

With that said, Xu Dayuan took the man out, and Zhou Ning blinked. He never expected that someone like him could one day be promoted as a brand.

After a while, Xu Dayuan came back quickly.

The look in Zhou Ning's eyes was different. He took off his hat and wiped the sweat from his forehead.

"Xiao Zhou is good. He observed very carefully. I thought it would take some effort to check the identity. I didn't expect that I found it everywhere. You can also record it here."

As he said this, he handed Zhou Ning a piece of paper. There was a picture of a girl on it, with a bright smile, flowing long hair, and a light yellow dress, all showing the atmosphere of youth. He knew that this was a picture of the deceased. In fact, it was a picture of the deceased.

It is difficult to connect them because the deceased's face has been deformed.

"The deceased's name is Su Manli. She was 17 years old. She was in the third year of the 3+4 nursing major. She did not study well and was a bit rebellious. She lived in an apartment next to the school. Her father opened a Volkswagen 4S store. In order to take care of business, he usually did not live in the city.

A visit to the school revealed that her boyfriend changed frequently. He either skipped school all day long or went singing and drinking with boys from outside the school. He was criticized every now and then. The teacher always said good things, and it seemed that her father had made him mature.

Along the way, his father kept saying that he suspected that someone was retaliating against him and harming the child, so we should quickly investigate his competitors. Okay, that's the general situation. Do you understand what more should be checked during the autopsy?

"

Zhou Ning was stunned, where is the elder brother guessing the riddle?

How do I, a simple person like me, know what you want to express? You just say no?

PS:

[1] Calculation of estimated time of death: According to domestic corpse temperature research reports, within 4 to 5 hours after death, the heat production in the body has not completely stopped, and the corpse temperature dropped by an average of 0.58 degrees per hour; 5 to 16 hours after death, the body temperature

When the heat completely stops, the corpse temperature drops by an average of 0.97 degrees per hour; 16 to 24 hours after death, because the temperature difference between the corpse and the environment shrinks, the corpse temperature drops slower, with an average drop of 0.54 degrees per hour. This study established

The formula for calculating the time of death, after practical application and improvement, is the following simple formula:

Time elapsed after death (hours) = 37 degrees - corpse rectal temperature / 0.83* coefficient

(The multiplication coefficients are: 1 in spring and autumn, 1.4 in summer, and 0.7 in winter.)
