Chapter 4, is the elder brother guessing riddles?
Zhou Ning bent down excitedly, leaning closer to the school emblem to observe it carefully
Uncertain how much time had passed, Zhou Ning opened his eyes and adjusted his glasses
Throughout the journey, his father kept saying that he suspected someone was retaliating against him, harming the child, and urged us to quickly investigate his competitors. Alright, I have outlined the general situation; do you understand what else should be examined during the autopsy?
Xu Dayuan laughed twice with a hearty laugh
The badge bore traces of blood, yet the four characters "Qidong Medical School" stood out prominently
Just hung up, Xu Dayuan's number flashed on the phone, and Zhou Ning quickly answered the call
Zhou Ning carefully reviewed it once again; this time, it was clearer than when he first received this forensic scene study.
Xu Dayuan nodded slightly at Zhou Ning, making an effort to soften his voice as he said
The female police officer tilted her chin slightly as she spoke, guiding the woman outside. The man took the tissue that Zhou Ning handed him to wipe away his tears, and only then did he look at the autopsy consent form that Zhou Ning had given him
Did forensic expert Xiao Zhou make any discoveries
Xiao Zhou is quite impressive, observing very carefully. I thought it would take some effort to check identities, but I really didn't expect to find it wherever I went. Please make a note of it here as well
"Dr. Zhou, are you in the autopsy room? I am bringing the deceased's family over for identification. Please prepare the consent form for the autopsy."
Xiao Zhou, your algorithm is correct. The temperature here is high, so we will calculate it using the summer coefficient. However, for Xu Da and the others, we only need a range for the time of death. Just like Xu Da reported, the estimated time of death is between 2:00 and 3:00 on September 27. Have we identified the deceased?
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 is available in the autopsy room, but he does not know how to use it
Xu Da, I borrowed Xiao Liu's police communication device to send you two photos. One is a facial photo of the deceased, and the other is the school badge found on the deceased. I suspect that the deceased is a student of Qidong Vocational School. Please try to identify them using the photos.
[1] Estimation of Time of Death: According to domestic research reports on corpse temperature, within 4 to 5 hours after death, the internal heat production has not completely ceased, and the average decrease in corpse temperature is 0.58 degrees per hour; from 5 to 16 hours after death, heat production completely stops, and the average decrease in corpse temperature is 0.97 degrees per hour; from 16 to 24 hours after death, due to the reduction in temperature difference between the corpse and the environment, the decrease in corpse temperature slows down, averaging a decline of 0.54 degrees per hour. This research established a formula for calculating the time of death, and through practical application and refinement, the following simplified formula was derived: from 5 to 16 hours after death, heat production completely stops, and the average decrease in corpse temperature is 0.97 degrees per hour; from 16 to 24 hours after death, due to the reduction in temperature difference between the corpse and the environment, the decrease in corpse temperature slows down, averaging a decline of 0.54 degrees per hour. This research established a formula for calculating the time of death, and through practical application and refinement, the following simplified formula was derived
This time there is no splitting headache, probably because it is not the kind of rote memorization, so there will be no headache
After hanging up the phone, Zhou Ning let out a sigh of relief and returned the police communication device to Xiao Liu. That kid dashed out without uttering another word. Seeing his cowardly demeanor, Zhou Ning suddenly felt that he was not so bad after all
PS:
I just mentioned receiving an award, but my mind is filled with concepts from forensic evidence science, such as blood drop identification, injury object inference, electronic evidence investigation, forensic scene analysis and reconstruction, on-site investigation of arson cases, and the examination of dismemberment cases and unidentified corpses.
Master, I would like to report to you that I measured the rectal temperature of the deceased to be 32.1 degrees. According to the formula 37 degrees minus the rectal temperature of the corpse divided by 0.83 multiplied by the coefficient, I deduce that the time of death is approximately 8.27 hours ago
Having understood these matters, Zhou Ning no longer feels like a headless fly. Since he is waiting for a call, he should not just wait idly.
At this moment, the identity of the deceased had not yet been confirmed, and Zhou Ning did not rush to act; instead, he held the splint and gently closed his eyes.
As he spoke, Xu Dayuan took the man outside. Zhou Ning blinked, realizing that he never expected to be promoted as a signboard one day, just like this
Time after death (hours) = 37 degrees - rectal temperature of the corpse / 0.83 * coefficient
Putting down the phone, Zhou Ning put on a disposable isolation suit, donned a hat, mask, and latex gloves. Zhou Ning picked up the clipboard, which had the printed records of the autopsy.
Xu Dayuan nodded slightly, patted the man's shoulder, and pointed at Zhou Ning, saying
In fact, it is possible to determine whether it is the deceased through photographs; coming to take a look is also to put an end to the final lingering thoughts.
Haha, very well, I will go to the school to identify it now
It was evident that the person's movements came to a halt
The man nodded, not engaging in much conversation like Xu Dayuan, took the autopsy consent form from Zhou Ning, signed it directly, and then glanced at Zhou Ning and Xu Dayuan before bowing at a ninety-degree angle.
Xu Dayuan seemed to be very familiar with such a situation, speaking to himself:
Then there is no need to rush, your work is very meticulous, just wait a moment, I will finish the IV drip and take a look in the dissection room.
Come closer and take a look, is it your little Man'er
I did not find it, but I discovered the nursing school badge on the deceased. Xu Da and the others have already gone to investigate.
Suspected: The deceased was a student of Qidong Vocational School?
Am I so lucky?
A wealth of detailed knowledge, even various现场 images, surged into Zhou Ning's mind, flashing like scenes from a movie. This knowledge was extremely comprehensive, accompanied by targeted case explanations, as if it were memories that inherently belonged to him
In the spacious dissection room, Zhou Ning rummaged through the desk beside the computer and finally found a consent form. Just as he was about to prepare it, the door of the dissection room was pushed open
As such a naive person, how can I know what you are trying to express? Can't you just say it directly
Just like in the novice village, if you do not find the NPC at the village entrance to trigger the quest, you simply cannot leave the novice village
During the school visit, it was learned that her boyfriend frequently changes, often skipping classes or going out with guys to sing and drink. He is criticized every few days, yet the teachers consistently speak well of him, seemingly having been well-trained by her father
After half an hour of effort, Zhou Ning recorded the rigor mortis state of the deceased's joints, held up the splint, and documented all the data before dialing Dr. Liu's number again
Xiao Liu closed the door, blocking the two individuals, and distributed masks to them. Zhou Ning took the consent form and went over, placing it between the autopsy table and the family members.
Alright
After all, as the old saying goes, one must see the living and the dead must be seen.
Xu Dayuan let out a sigh, and this expression was self-evident; however, the necessary procedures still had to be followed
Finding this will make it easier to identify the deceased. Zhou Ning quickly wiped the bloodstains clean and took close-up shots of the school badge and the deceased's face
Brother, at our age, every family has children. I understand your feelings. I cannot stand seeing such a murderer go unpunished. Look, this is our new talented recruit; he is the one who uncovered your daughter Xiaoman's identity. We have professionals who will spare no effort in solving this case. Come, let's talk with our officers first and provide some information.
Zhou Ning swallowed hard, suppressing his excitement, and said with an effort to appear calm:
Xiao Liu quickly nodded and took out a seemingly advanced mobile phone from his pocket
Turning around to close the door, the auxiliary police officer Xiao Liu, who was waiting outside, peeked in
The two leaned in for a closer look; the man was fine, but the woman immediately weakened in her legs and collapsed to the ground, her cries filling the autopsy room.
My little Man'er passed away too suddenly. I implore Officer Xu to do everything possible to solve the case and catch the murderer as soon as possible
The image of the corpse, along with the various known information beside it, remains unchanged; only an additional sentence has appeared next to the corpse's head
Zhou Ning did not waste any words, took the device and walked to the old computer in the dissection room, transferred the photos, directly searched for Xu Da on it, and clicked send
He handed Zhou Ning a piece of paper, which had a photo of a girl on it, with a radiant smile, flowing long hair, and a light yellow long dress, all of which exuded the essence of youth. He knew this was a photo of the deceased, and it was actually quite difficult to connect them, after all, the deceased's face had already become distorted.
The deceased is Su Manli, aged 17, a third-year nursing student in the 3 + 4 program, who struggles academically and exhibits a bit of rebellious behavior. She lived in an apartment next to the school, while her father operates a Volkswagen dealership and usually does not reside in the city to take care of the business
In a moment, Xu Dayuan returned quickly.
... ...
( The coefficients are: 1 for spring and autumn, 1.4 for summer, and 0.7 for winter )
Upon hearing what Medical Examiner Liu said, Zhou Ning also felt relieved and promptly hung up the phone
Xiao Liu, do you have the police communication device on you? I need to send the deceased's photo to Xu Da
What happened, Dr. Zhou?
Subsequently, I dialed Xu Da's mobile number, and after a single ring, the call was answered immediately on the other end
The time I measured was 10:50 AM, which indicates that the time of death was at 2:23 AM. The deceased only exhibited rigor mortis in the small joints such as the fingers and jaw, which is consistent with the inference from the rectal temperature. Master, how should I write this report on the time of death?
Zhou Ning was taken aback, is elder brother guessing a riddle
You two should control your emotions; we have many issues to discuss with you. The child is gone, and it cannot remain so unclear. Finding the murderer is the most important matter. First, please sign the consent form, and then we can discuss the details outside.
Look at Zhou Ning's gaze. It is completely different now, as he takes off his hat and wipes the sweat from his forehead
The forensic expert Liu on the opposite side let out a hiss, unsure if he had hit a painful spot
Xu Dayuan entered with a man and a woman, followed by a female police officer of a certain seniority. Looking at the nervous expressions of the two, it was clear that they were direct relatives
In fact, according to the procedure, in cases involving criminal offenses, we can conduct an autopsy directly without the consent of the family. However, since the identity of the deceased is unknown, we would like to wait for you to take a look before proceeding. Although this has already caused a delay, taking a little more time may slightly increase the chances of capturing the perpetrator
As for the system, it is quite silent, not providing any prompts for new tasks. It seems that during the autopsy, there are some discoveries that are summarized within the system, but he needs to rely on himself to obtain these findings. Without making progress, he cannot trigger the system prompts.
