"I received the news at one o'clock, arrived before 2 o'clock, and then took the rectal temperature. It was 34.5 degrees."
Ye Tianhe didn't hesitate and directly took out the future tense measurement data.
To identify the time of death, it is relatively easy to draw a rough conclusion, but it is extremely difficult to draw an accurate conclusion, especially a more precise conclusion.
Just the rectal temperature alone has very complicated content.
In 1984, the ministry organized a corpse temperature research team to study the relationship between death time and the rectal temperature data of 581 corpses at 0 to 30 degrees Celsius, and finally derived 27 ternary regression equations.
Many subsequent corpse temperature studies in the country are actually based on this time, because it is too difficult for later people to obtain 500 corpses. If there are so many corpses, it is equivalent to using them for rectal temperature research.
Sun Wukong immobilized the seven fairies and ran to steal a peach.
After all, not many people can really remember the 27 three-variable regression equations. Everyone just checks them when they are used.
Furthermore, most forensic scientists actually use a simplified version of the regression equation. Some don't even bother to use the regression equation, and just use it based on experience, such as reducing it by one degree per hour, or by 0.8 degrees. If you are more particular, divide it further.
The ambient temperature is about the same.
Therefore, when Ye Tianhe found that Jiang Yuan was very serious and confident, he stopped arguing and gave the data directly. If you can calculate it, then you can do it.
However, Jiang Yuan just said "en" and said: "Anal temperature is not decisive."
Only then did Ye Tianhe remember that Jiang Yuan came in without even taking his rectal temperature.
You haven’t measured your rectal temperature, so you want to play with me about the precise time of death?
Ye Tianhe just thought of Yu Wenshu and didn't want to be the man who stretched his legs.
But Ye Tianhe also had a temper, and said directly: "Let's measure the liver temperature."
Liver temperature is much more accurate than rectal temperature, but liver temperature is destructive. An incision has to be made at the waist, and the body surface will not be so complete. According to domestic customs, in this case, it is often necessary to explain to the family members.
In addition, forensic doctors tend to do this kind of invasive operation after returning to the dissecting room. As a result, the timeliness is not as good as that of rectal temperature.
Therefore, when it is not necessary, everyone tends to measure the rectal temperature. Generally speaking, it is enough.
As for now, there was a time difference, so Ye Tianhe didn't hesitate and directly asked to take the liver temperature.
Wan Baoming was a little confused. He coughed twice and said, "Then I'll discuss it with Captain Ma."
Captain Ma is the captain of the Second Brigade of the Criminal Police Detachment. After confirming that it was a murder, Captain Ma rushed over immediately. However, because the husband of the deceased was the biggest suspect, Captain Ma did not show up immediately. Everyone still followed the murderer's script.
, pretending to be a suicide case for examination.
This is where Wanbaoming struggled. If he asked his husband to take the liver temperature, it would easily alert him. This decision had to be made by the Ma brigade in charge of the scene.
Wan Baoming called, and within two minutes, Ma Jiyang came in, having changed his clothes.
"I heard that there is a difference in time?" Ma Jiyang is a somewhat sturdy man with long legs and clean police pants. This means that the family members of the victims of bullying do not understand. Otherwise, you can tell at a glance that he is in a family-owned state.
A good wife, or the type who is a good wife herself, is very unlike a grassroots police officer.
Wan Baoming rushed to say: "The time difference is not much, that is, one hour, but Jiang Yuan's judgment means that the victim's husband has been ruled out."
"That's not necessarily ruled out." Ma Jiyang thought carefully and quickly, and asked: "The husband of the deceased came back around 11 o'clock or 12 o'clock, and the elevator camera took it. Jiang Yuan, what time did you estimate the death time?
"
"A quarter past ten," Jiang Yuandao said.
"So accurate?" Ma Jiyang looked at Jiang Yuan. His Second Criminal Police Brigade often handled murder cases. In fact, he had handled the backlog of murder cases that Jiang Yuan had done before.
The current case that he had not been able to solve back then was solved by Jiang Yuan despite the backlog of cases, and the case was solved very beautifully. Ma Jiyang could be said to be extremely impressed.
Therefore, when he met Jiang Yuan this time, Ma Jiyang instinctively gave him more trust bonus.
But Jiang Yuan directly reported an accurate number, which still made Ma Jiyang a little confused.
Jiang Yuan said "En". What can I say? Anyway, LV6 is so awesome. For such murders within 6 hours, he can directly give the accurate time of death.
Ma Jiyang didn't wait for the explanation. Then he thought, come on, what will happen if I hear the explanation?
Out of politeness, Ma Jiyang looked at Ye Tianhe and said a little warmly: "Forensic doctor Ye, you are here to analyze."
"11 o'clock to 12 o'clock." Ye Tianhe stopped saying a quarter past ten. The rectal temperature he measured was left there, and the state of rigor mortis also met the time limit. A normal forensic doctor should come to the same conclusion.
.
Ma Jiyang said "Oh" and said: "That's actually only 45 minutes. As for whether the husband of the deceased has an alibi because of this... The elevator queue came back after 11 o'clock, but we can't deny that he came back at 10 o'clock, or 11 o'clock.
Click to come back..."
Wan Baoming reminded: "You can ask more carefully about the time when the deceased's husband left the unit."
"Well, if it's really a lie, the unit's check-in time can also be faked." Ma Jiyang said, his expression still much heavier.
After a blink of an eye, Ma Jiyang smiled again and said: "By the way, you said you want to measure the liver temperature?"
"Let's take a liver temperature test to make sure." Wanbaoming explained on his behalf.
Ma Jiyang said "Yes": "Let's take a test, it's all here."
"Do you want to tell the husband of the deceased?"
"Don't say it. You can just test it directly. This body must be brought back, so there is no need to add any complications."
Ma Jiyang made a decision, so Ye Tianhe and others didn't have to worry so much. He took out the liver temperature needle, poked it in and took a test.
"32 degrees 1." Ye Tianhe read the number and calculated silently. He was sure that it supported his judgment, so he asked Jiang Yuan: "Forensic Doctor Jiang, can you test it?"
"No, this shows that the temperature of the corpse is generally disordered." Jiang Yuan gave some explanation.
Ye Tianhe was speechless and said: "You can't say that the liver temperature is not as expected, just say that the temperature of the corpse is disordered. This... you have to talk about the evidence."
"The temperature of the corpse is only one of the criteria for judging the time of death. In fact, it is also the most susceptible to interference." Jiang Yuan said calmly, and then said: "The super-reaction of the corpse, such as the super-reaction of the muscles, and the cornea.
Changes, rigor mortis, pay attention to the shrinkage of the lips..."
When Jiang Yuan said this, he paused and then said: "When we go back to do the dissection, we will check the digestion of the stomach contents and do a toxicology..."
Some drugs will affect changes in body temperature, such as antipyretics.
Seeing Jiang Yuan's certainty, Ye Tianhe had to readjust his mood and said, "Okay, let's take a look during the autopsy."
Jiang Yuan's purpose was not to convince him, so he stopped talking and just stood up and observed the scene.
Ma Jiyang asked: "What are you looking for?"
Jiang Yuandao: "Actually, there is such a big difference in the time of death based on corpse temperature, which is a bit problematic."
"How to say?"
"There are many reasons that determine the temperature of a corpse. But generally speaking, the main ones are the ambient temperature, clothing or coverings, the carrier of the corpse, the ventilation of the environment, humidity, gender, age, body shape, cause of death, drugs..." Jiang Yuanyi
He named 10 kinds in one tone, and then said: "Among them, the latter ones are not easy to change, and the ones that are easy to change are the first ones..."
Ma Jiyang closed his eyes as he listened and felt the environment of the crime scene.
Jiang Yuan pondered and said: "If we think about the changes, the humidity in the bathroom is relatively high, there is an exhaust fan for ventilation, there is a fresh air system here, and the body is hung..."
Ma Jiyang opened his eyes, and the pressure returned instantly, and said: "The relationship between the deceased and her husband was not very good, and they had a quarrel recently. In addition, the financial problems between the two were also prominent, and the deceased still had insurance... I will go and make sure this
Guy’s itinerary.”
Psychologically, Ma Jiyang still felt that her husband was the most suspicious.
However, Jiang Yuan's performance these days still made him willing to investigate more.
