National Forensic Doctor

"I received the news at one o'clock, arrived before 2 o'clock, and then took the rectal temperature. It was 5 degrees."

Ye Tianhe didn't hesitate and directly took out the future time measurement data.

To identify the time of death, it is relatively easy to draw a rough conclusion, but it is very 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 were actually based on this time, because it was too difficult for subsequent people to obtain 500 corpses. If there are really so many corpses used for rectal temperature research, it is equivalent to Monkey King immobilizing the Seven Fairies and running away to steal a peach.

After all, few people can really remember the 27 three-variable regression equations. Everyone will check again after using it.

Furthermore, what most forensic scientists use is actually a simplified version of the regression equation. Some people don't even bother to use regression equations, and just rely on experience, such as reducing the temperature by one degree per hour, or by 8 degrees. If you're more particular, you can divide the ambient temperature, and that's about it.

Therefore, when Ye Tianhe discovered that Jiang Yuan was very serious and confident, he stopped arguing and gave him the data directly. If you can figure it out, then just 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.

I didn’t measure my rectal temperature, so you’re just trying to play with me about the exact 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: "Then let's measure the liver temperature."

Liver temperature is much more accurate than rectal temperature, but liver temperature is destructive. A hole has to be made in the waist, and the body surface will not be so complete.

According to domestic custom, 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 autopsy room. As a result, the timeliness is not as good as the 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 case, Captain Ma rushed over immediately. But since the deceased's husband was the biggest suspect, the Ma brigade did not show up immediately. Everyone still followed the murderer's script and pretended to be a suicide case for inspection. This is where Wanbaoming struggles. If he asks his husband to measure his liver temperature, it will easily alert him. This decision must be made by the Ma brigade responsible for the scene.

Wan Baoming made a call, and in less than two minutes, Ma Jiyang, who had changed his clothes, came in.

"I heard that there is a difference in time?" Ma Jiyang is a sturdy man with long legs and clean police pants. This means that the family members of the victims of bullying do not understand. Otherwise, it can be seen at a glance that he is a family member. 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 according to Jiang Yuan's judgment, 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 handles murder cases. In fact, he has handled some of Jiang Yuan's previous backlog of murder cases.

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 detection was very beautiful. Ma Jiyang could say that he was 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 "Yes". What can I say? Anyway, LV6 is so awesome. He can directly give the accurate time of death for this kind of murder within 6 hours.

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 warmly: "Forensic Doctor Ye, you are here to analyze."

"11 to 12 o'clock." Ye Tianhe stopped saying a quarter past ten.

The rectal temperature he measured was left there, and the rigor mortis condition met the time limit. A normal forensic doctor would have come to a similar 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 it cannot be denied that he came back at 10 o'clock, or 11 Click 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 check the liver temperature 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, and Ye Tianhe and others didn't have to worry so much. Take out the liver temperature needle, poke it in and take a test.

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

"No, this shows that the body temperature 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 body temperature 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, the changes in the cornea, and 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 still 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 Yuan named 10 types in one breath, and then said: "Among them, the latter ones are not easy to change. What Rong Nan changed was the first ones." Ma Jiyang closed his eyes after listening, feeling Crime scene environment.”

Jiang Yuan thought about it 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 heavy 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. The deceased still had insurance... I will go and confirm this.

Guy's trip. "

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.
