Chapter 305 Temperature
"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 bother, and directly took out the data measured in the future.

For the identification of the time of death, it is relatively easy to draw a general conclusion, but it is extremely difficult to draw an accurate conclusion, especially a more precise conclusion.

There are very complicated contents in the item of rectal temperature alone.

In 84, the ministries and commissions once organized a corpse temperature research team to study the relationship between death time and the rectal temperature data of 0 corpses at 30 to 581 degrees Celsius, and finally deduced 27 ternary regression equations.

Many follow-up studies on body temperature in China are actually based on this time, because it is too difficult for the people behind to get 500 corpses.There are really so many corpses for rectal temperature research, which is equivalent to Monkey King catching the Seven Fairies and stealing a peach.

After all, there are not many people who can really remember the 27 ternary regression equations.Everyone will check again when they use it.

Furthermore, most forensics use a simplified version of the regression equation.Some don't even bother to use the regression equation, and just follow the experience, such as dropping one degree per hour, or 0.8 degrees, and if you pay more attention to the ambient temperature, it's almost the same.

Therefore, when Ye Tianhe found out that Jiang Yuan was very serious and confident, he didn't argue, and directly gave the data, if you can figure it out, you can just count it.

However, Jiang Yuan just said "En", and said: "Anal temperature is not decisive."

Ye Tianhe only remembered at this time that Jiang Yuan came in without even measuring his rectal temperature.

I didn't measure the rectal temperature, so just play with me with this precise time of death?
Ye Tianhe just thought of Yu Wenshu, and didn't want to be that man who stretched his feet.

But Ye Tianhe also has a temper, and said directly: "Then 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 watch is not so complete.According to the domestic custom, this kind of situation often needs to be explained to the family members.

In addition, forensic doctors tend to go back to the dissection room for this kind of invasive operation, so the immediacy is not as good as rectal temperature.

Therefore, when it is not necessary, everyone tends to measure the rectal temperature. Generally speaking, it is enough.

As for now, if there is a time difference, Ye Tianhe doesn't get entangled, and directly asks for a liver temperature test.

On the contrary, Wan Baoming got a little tangled up, coughed twice, and said, "Then I'll discuss it with Team Ma."

Team Ma is the captain of the Second Brigade of the Criminal Police Detachment. After confirming that it was a murder case, Captain Ma rushed over immediately.However, since the husband of the deceased was the biggest suspect, Team Ma did not show up immediately. Everyone still followed the murderer's script and pretended it was a suicide case for investigation.

This is where Wan Baoming struggled. If he asked his husband to measure his liver temperature, it would be easy for him to wake up.This decision has to be made by the Ma brigade in charge of the scene.

Wan Baoming made a phone call, and within 2 minutes, Ma Jiyang came in after changing clothes.

"I heard there is a difference in time?" Ma Jiyang is a somewhat burly man with long legs and clean police trousers, that is, the family members of the bullying victim don't understand, otherwise, it can be seen at a glance that his condition is family owned. A virtuous wife, or the type of a virtuous wife herself, is not like a grassroots policeman.

Wan Baoming hurriedly said: "There is not much time difference, that is, one hour, but according to Jiang Yuan's judgment, the victim's husband was excluded."

"That may not necessarily be ruled out." Ma Jiyang thought carefully and quickly, and asked: "The husband of the deceased came back around 11:12 or [-]:[-], and the elevator camera took it. Jiang Yuan, what time did you judge the death time? "

"A quarter past ten." Jiang Yuan said.

"So accurate?" Ma Jiyang looked at Jiang Yuan.His Second Brigade of Criminal Police often handles murder cases. In fact, he has handled Jiang Yuan's previous homicide cases.

The current case that he failed to solve back then was solved by Jiang Yuan in the state of accumulated cases, and the detection was very beautiful, Ma Jiyang can be said to be in admiration.

Therefore, seeing 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 to say, anyway, LV6 is so awesome, this kind of homicide within 6 hours, he can directly give the exact time of death.

Ma Jiyang didn't wait for an explanation, so he thought about it, come on, what can I do if I hear the explanation?

Out of politeness, Ma Jiyang looked at Ye Tianhe, but said a little warmly: "Ye Fayi, you are analyzing it."

"11:12 to [-]:[-]." Ye Tianhe stopped talking about a quarter past ten.The rectal temperature he measured was placed there, and the rigor state also met the time limit. If a normal forensic doctor came over, it should be the same conclusion.

Ma Jiyang let out an "oh" and said, "That's actually 45 minutes away. As for whether the husband of the deceased has an alibi because of this... the elevator lined up to come back after 11 o'clock, and it cannot be denied that he will come back at 10 o'clock, or 11 o'clock." Come back later..."

Wan Baoming reminded: "When the husband of the deceased left the unit, you can ask more carefully."

"Well, if it's really a fake, the clock-in time of the unit can also be fake." After Ma Jiyang said it, his expression was still a lot heavier.

In 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." Wan Baoming explained on his behalf.

Ma Jiyang said "En", "Test it, it's all here."

"Do you want to tell the husband of the deceased?"

"Don't talk about it. You can just measure it directly. This corpse will definitely be brought back, so there is no need to make extra troubles."

Ma Jiyang has made a decision, so Ye Tianhe and the others don't have to be so entangled.Take out the liver temperature needle, poke it in and measure it.

"32 degrees 1." Ye Tianhe read the number, calculated silently, and was sure that his judgment was supported, so he asked Jiang Yuan: "Jiang Forensic Doctor, can you measure it?"

"No, this shows that the temperature of the body is disordered as a whole." Jiang Yuan gave an explanation.

Ye Tianhe was speechless, and said: "You can't say that the liver temperature does not meet expectations, but say that the temperature of the body is disordered. This... must be based on 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 easily disturbed." Jiang Yuan said in a calm manner, and then said: "The supernatural reaction of the corpse, such as the supernatural reaction of the muscle, and the cornea. Changes, and rigor, pay attention to the shrinking of the lips..."

When Jiang Yuan said this, he paused for a moment, and said again: "When you go back to do the autopsy, look at the digestion of the stomach contents, and do a toxicology..."

Some drugs will affect the temperature of the corpse, such as antipyretics.

Seeing that Jiang Yuan was so sure, 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 persuade him, so he didn't talk too much, he just stood up and observed the scene.

Ma Jiyang asked: "What are you looking for?"

Jiang Yuandao: "Actually, the time of death based on the body temperature has such a large gap, which is still a bit of a problem."

"How to say?"

"There are many factors 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, and drugs..." Jiang Yuanyi He said 10 kinds in one breath, and then said: "Among them, the latter ones are not easy to change, and the ones that are easy to change are the first few..."

Ma Jiyang closed his eyes and felt the environment of the crime scene.

Jiang Yuan thought about it, and said: "If you want to consider the change, the humidity in the bathroom is relatively high, there is an exhaust fan for ventilation, and there is a fresh air system here, and the corpse is hoisted..."

Ma Jiyang opened his eyes, and the pressure returned in an instant, and said: "The relationship between the deceased and her husband is not very good, and there have been quarrels recently. In addition, the financial problems of the two are also prominent, and the deceased still has insurance... I will make sure about 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.
