Kang Zhichao picked up the photo handed over by Jiang Yuan and read it carefully.
After watching for a while, he took out his laptop from under his seat, went on the intranet, and looked through the previous autopsy reports and photos.
Feng Qiong waited for him for almost ten minutes.
During this period, no one spoke in the conference room.
The answer Jiang Yuan gave has too great an impact.
The identification of the time of death is not only extremely important in forensic medicine, but also in criminal investigation practice.
For example, half of the famous "Perfect Murder" in mystery novels uses "alibi", that is, the use of the time of death. The murderer used a refrigerator, an air conditioner, and a meter adjuster.
road...
Most of the murderers here encountered mediocre forensic doctors who were too responsible. So much so that they always gave an accurate time of death to facilitate misjudgment by the police.
In fact, it is basically impossible for a normal forensic doctor to accurately determine the time of death to the hour. For a death within 24 hours, a figure of 8 to 10 hours, or 3 to 5 hours is already very reluctant. After all, there are
Data such as liver temperature provide support.
Once the death exceeds 24 hours, it will be difficult to give a more accurate value. It is not completely impossible, but the technology used is no longer within the grasp of ordinary forensic doctors.
As for cases where the death lasts longer, the more precise the requirements, the higher the difficulty.
The information that forensic doctors can rely on is basically non-standard. Such as liver temperature, insect species and generational relationships, rigor mortis and cadaveric plaques, changes in microbial communities, the degree of ATP degradation in red blood cells, and even the condition of postmortem skin.
Infrared Fourier transform can be used to identify the time of death.
But look at this problem from another perspective: If there is a technology that can simply and crudely identify the time of death of a corpse, are these scientists so brain-burned that they use various methods to identify it?
As the saying goes, good students have more stationery than bad students. The more technologies and methods are developed to calculate a numerical value, it means that it is difficult to calculate this numerical value accurately.
As for the 503 case, if the first victim is a policeman with a gun, then the case is most likely that the two criminals stole the gun or grabbed the gun, then killed the victim and took the gun with them to try more and more efficiently
of robbery.
At this time, if we want to detect the case positively, we must consider the first victim more. It can basically be determined that the criminal went for the gun.
Because if you want to murder someone, you can choose a time when the policeman is not holding a gun, and there is no need to carry out multiple subsequent robberies.
There are many similar cases, such as the famous gangster Bai Baoshan, who started his robbery by attacking a sentry to seize a gun.
Then, following the idea of killing by gun and robbery as the direction of criminal investigation, it is natural to consider the disposal of property, the murderer's familiarity with armed police officers, the planning of the robbery route, the planning of the robbery method, and the follow-up
The planning of the robbery plan, etc.
However, if the first person killed by the murderer is actually victim number two, the situation will be reversed instantly.
Killing Victim No. 2 first and then Victim No. 1 means that the murderer’s original target was probably Victim No. 2, and Victim No. 1, as a policeman with a gun returning home from get off work, is more likely to have bumped into him. The murderer was killed in a conflict.
As a result, the direction of criminal investigation based on the idea of killing people is tantamount to a total waste. The investigation of victim No. 2 must be rethought from the perspective of murder or wealth.
Various emotions, various thoughts, and various realities flowed in the conference room.
Feng Qiong couldn't wait any longer and turned to ask Kang Zhichao: "How is it?"
"Are you asking me?" Kang Zhichao was still looking at the photos in his notebook carefully.
"That's right. What else?" Feng Qiong knew that his colleague was a bit stupid, but there was nothing he could do about it. Even in ministries, you couldn't expect your colleagues to have good skills, good personalities, stable emotions, be good-looking, be indifferent and clear-minded, and endure hardships.
Hard work, the so-called impossible hexagon.
Kang Zhichao looked up and found that everyone was looking at him, so he said, "I'm asking people too."
"Ask who?"
"Old Tao." Kang Zhichao paused and then said: "I'm a half-baked forensic doctor. I just learned it later. Let Lao Tao take a look."
Feng Qiong had no choice but to take a breath and asked: "What did Lao Tao say?"
"Old Tao." Kang Zhichao glanced at the laptop and said, "I'll paraphrase his original words, just one sentence: So awesome? A question."
"Then what?"
"Gone."
The two people spoke in front of everyone, and the content was not concealed. A group of county police officers looked at each other. How dare the leaders from the ministries and commissions, the case cannot be carried out, and the action of blaming the blame was like this?
"Have a cigarette."
The director handed Feng Qiong a cigarette, and he was in a good mood.
If this case goes as planned by Jiang Yuan, then Feng Qiong and others should return to Anhai City and use the manpower of the Anhai City Bureau to investigate and collect evidence in Anhai.
For the Miaohe County Bureau, it is true that there are fewer opportunities to make meritorious services, but one thing is, can the small Miaohe County Bureau grasp the opportunity given to such an unsolved case?
It's really better to get out early.
Director Guan Xingfu unconsciously glanced at Jiang Yuan and thought: In comparison, finding a dog for Jiang Yuan might be more reliable.
Woohoo...
Kang Zhichao's cell phone vibrated.
He picked it up, looked at it, and said, "Old Tao's."
"Let's turn on speakerphone." Feng Qiong rubbed his eyes and stopped pretending.
This case has now reached a fork in the road. If it is proven that Jiang Yuan is talking nonsense, then they can clearly take the photos and continue the investigation in Miaohe County. If it is proven that Jiang Yuan is not talking nonsense, then they should leave Miaohe County.
, at this moment, it is meaningless to pay attention to image, majesty and so on.
Kang Zhichao answered the phone and said: "Old Tao, turn on the speakerphone. We are having a meeting. Next to us are Feng Qiong, several leaders from the Miaohe County Bureau, and relevant police officers."
"There are a lot of people." Old Tao shouted and asked, "Um, is the forensic doctor Jiang I just mentioned here?"
"Next to me." Feng Qiong said directly: "Old Tao, just give your conclusion, don't worry."
Lao Tao said "Ah" and said: "I have no conclusion. You want to ask me whether I can see the time difference between the two. In the photo, I really can't be sure. But, you ask me to deny this judgment.
I can’t do it either. I know I said something like a wheel, I’m only one, but..."
Lao Tao paused for a moment and said: "Relatively speaking, I am more inclined to conclude that victim No. 2 died first. However, I think this specific judgment, especially the time of death, should be discussed with Medical Examiner Jiang.
Forensic Doctor Jiang?”
"I'm here." Jiang Yuan responded and said: "From the photos, the death time of the two is indeed relatively similar, only about an hour apart. I think the specific time can be compared through the cornea of the eye.
.”
"I saw the two photos you sent. As for the corneas... I don't see much difference..." Lao Tao was obviously looking at the photos on the other end of the phone, but his voice was uncertain.
Jiang Yuandao: "The condition of the cornea is close, which is actually the problem. If you look at other photos, the policeman with the gun had his eyes open after death, and the deceased No. 2 had his eyes closed after death. In addition, after the death of No. 2, his eyes were closed.
It should have been put into the trunk. In a relatively anaerobic environment, excessive lactic acid produced by the corneal epithelium will cause swelling and turbidity of the corneal stroma. The environment in the trunk is airtight, and corneal turbidity will appear relatively quickly.
In addition, when No. 1 keeps his eyes open, the water in the cornea will evaporate faster, and the corneal turbidity will appear slower. Here, the degree of corneal turbidity has changed. You need to compare it..."
He knew Lao Tao's pain points. Although forensic medicine is very practical, when it comes to such details, it is still academic in the final analysis.
At this time, Jiang Yuan, with his LV6 time-of-death identification skills, naturally knew the difficulties of identification for lower-level forensic doctors. It was like a great teacher teaching a class and knowing the pain points of his students.
The old man on the other end of the phone suddenly said "oh" and then fell silent for a long time.
Feng Qiong waited for a few minutes and then said helplessly: "Why are you technical people talking and not saying anything?"
Lao Tao hissed, as if he had woken up, and said, "Lao Kang, what did you say?"
Kang Zhichao, who was asked, did not answer and said: "I do the trace inspection, you have the final say."
Lao Tao did his part, laughed twice, and said: "Then I will follow Feng Chu's request just now and give the conclusion first. Awesome!"
