The first two priorities of homicide detection are to confirm the identity of the deceased and the cause of death.

Qin Lin saw that the fat man was not good in the small courtyard full of water and rubble, so he asked his soldiers to pull a white sheet, put the charred corpse on it, and carried it to a clean place outside the courtyard to put it down.

Poor Zhang Xiaoyang vomited twice, his stomach vomited so much that only sour water remained, he was hiding on the side to rest, and caught up with Qin Lin and asked his own soldiers to carry the scorched corpse out, and once again bluffed him into straight eyes.

"Our family, our family is going to relieve our hands, Zeng Shilang, Chief Qin, see you later," Zhang Xiaoyang had a white face, and quickly urinated.

Just now, Zhao Shichen had been blocked by Qin Lin from entering the courtyard, and he had a grudge in his heart, and when he heard Qin Lin say that he had to verify the cause and identity of the deceased, he couldn't help but sneer: "The deceased is in the courtyard where Master Liu lives, and his body length can be closed, could it be someone else?" Moreover, this person was burned to death, we can see it for all to see, could Qin Qincha still think that he drowned? ”

After speaking, Zhao Shichen thought he was proud, and he had to laugh twice in the jackal's voice.

Qin Lin didn't speak for a long time, staring at Zhao Shichen with a smile, and the two cold eyes stared at him so much that his heart was furious, and finally he said slowly: "Who said that the charred corpse found in the fire must have been burned to death, maybe it was burned after death?" As for the identity of this person, it is better to confirm it, otherwise even if Mr. Zhao is not worried, Governor Yang will inevitably be worried. ”

Yang Zhao and Zhao Shichen were stabbed severely, as the saying goes, being a thief has a weak heart, so they were a little uncomfortable, and laughed dryly, but they couldn't find anything to refute.

Although the analysis of the case and the length of the deceased are consistent with Liu Liangfu, Qin Lin has always been rigorous and pragmatic in the process of investigation, and will never use indirect inferences if there is direct physical evidence, and must be verified and implemented before it can be accepted in any case.

Zeng Xingwu looked at the scorched corpse and frowned: "Not only have the facial features been damaged, but even if there are any black moles and scars on the body surface, you can't see it, how can you verify whether it is Liu Liangfu?" ”

There are so many ways to verify it!

In the past, Qin Lin had at least seven or eight ways to verify this kind of charred corpse, such as checking the deceased's dentist records, comparing the teeth in the corpse's mouth, and taking human tissue that had not been burned deep in the corpse to verify the DNA...... But now he can't have professional dentist records, let alone DNA testing equipment, how can he find out the identity of the deceased?

Qin Lin has a simpler and smarter way.

"Fatty, cut open the stomach of the charred corpse and look at the stomach contents," Qin Lin ordered straightforwardly.

Lu Yuanzhi has been accustomed to seeing his father kill pigs since he was a child, and he has been accustomed to following Qin Lin in the past two years, and immediately obeyed the order to cut open the stomach of the charred corpse with a knife and cut open the stomach pouch for examination.

When the charred corpse moved out, people who were a little less timid ran away, such as Zhang Xiaoyang; Qi Jiguang and Qi Jin have seen a lot of bloodshed and murder on the battlefield, of course they are not afraid, but when they saw the scene of Lu Fatzi dissecting the stomach pouch of the corpse and examining the food inside, they couldn't help but feel nauseous.

Qin Lin and his subordinates are all ruthless characters who are bold and hairy!

The fat man looked at it and immediately reported loudly: "Brother Qin, the stomach contents of the corpse include moldy dried vegetables, moldy tofu and other things, the food is basically in the stomach, and the intestines are empty." ”

"Sure enough, it's Liu Liangfu," Xu Wenchang nodded: "The Shaoxing moldy dried vegetables and moldy tofu that the old man invited him to eat, these things are not sold in Miyun." ”

Qin Lin not only confirmed the identity of the deceased, but also knew the time of death.

The digestive juices secreted by the human body dissolve the food, and the peristalsis of the gastrointestinal tract transports the food downward, and both digestive functions will stop immediately after death, so the degree of digestion of the stomach contents and the entry into the intestines can determine how long the deceased died until his last meal.

Combined with Liu Liangfu's age and physical condition, his digestive function before his death was probably average, if the rice, vegetables and meat fiber found in the stomach were relatively intact, and a small amount of food entered the duodenum, it can be determined that one or two were killed after eating; If the food has been digested into chyle, the food has entered the large intestine, or even the stomach has been largely emptied, the time of death can be assumed to be four to six hours after the meal.

As for the charred corpse dissected by Lu Yuanzhi, the stomach contents were clear and complete, basically did not become chyle, and there was no food in the duodenum, so it can be determined that he was killed about half an hour after eating.

Calculate that Xu Wenchang said goodbye and left after eating, and went to this courtyard to light a fire, almost half an hour apart, then it can be concluded that Liu Liangfu died before and after the fire.

After Qin Lin finished talking about this, Zeng Xingwu and Qi Jiguang listened very attentively, Yang Zhao and Zhao Shichen disagreed on their faces, but they were secretly afraid in their hearts, they really didn't expect Qin Lin to solve the case so powerfully, they looked at each other, and there was some hidden fear in their eyes...... "Since it is true that he died before and after the fire, can it be concluded that he really died by fire?" Zeng Xingwu asked humbly.

Qin Lin smiled: "Since the corpse is here, let's let it speak for itself and tell us the truth!" ”

Let the corpse speak?

Although it was daylight, the north wind blew people all over the body, looking at this charred black carbonized body, open black hole hole, extremely terrifying charred corpse, people couldn't help but drum in their hearts.

The victim's dying grievances seemed to be sealed in the corpse, and only Qin Lin could break the gap between yin and yang and listen to their complaints.

He ordered Fat Lu to cut open the chest cavity of the charred corpse, and immediately the lungs and respiratory tract were exposed.

The deceased's respiratory tract was filled with black toner, which is direct evidence of burning to death before death, and the alveoli were swollen and ruptured, showing an obvious "respiratory fever syndrome" - the phenomenon of respiratory burns caused by inhaling hot gases before death.

So far, the identity of the deceased, the cause of death, and the time of death have been revealed to the world, and the facts of the case have been further clarified: Liu Liangfu burned alive in the courtyard of the courtyard where he lived about half an hour after having dinner with Xu Wenchang.

Yang Zhao and Zhao Shichen originally thought that Qin Lin was going to say something earth-shattering, but they were greatly relieved when they heard this, it seemed that the progress of the matter was completely within their control.

Zhao Shichen sneered: "Hahaha, what Qin Qincha said, it is all a well-known thing, at the beginning of finding the scorched corpse, did someone say that it was not Liu Liangfu?" Seeing the flames soaring into the sky, who denies that he was burned alive? ”

Yes, Zeng Xingwu also looked at Qin Lin in confusion, and at present, it seems that what he has done is not very helpful to the investigation of the case.

Isn't it really big?

Qin Lin smiled slightly: "Since we are sure that Liu Liangfu was burned alive, rather than being killed first and then cremated, then this is the first scene of his death, and from the fire to his death, there must be a time interval, Liu Liangfu, who knows that he will definitely die, will it ......?"

"Leave us a message of death!" Zeng Xingwu, Qi Jiguang, and Lu Fatzi slapped their thighs at the same time, and suddenly realized.

Yang Zhao and Zhao Shichen glanced at each other, their hearts were pounding, and their expressions changed a few times.

Zhao Shichen thought for a while, leaned over, and lowered his voice: "Impossible, there is no paper and pen in the room - some of them have been burned to ashes with the bottom account, and Liu Liangfu has been tied to his hands and feet with silk ribbons that are easy to burn, what words can he leave behind?" ”

Yang Zhao nodded, and settled down a little, it was indeed as Zhao Shichen said, their arrangement was quite thorough, how could it be possible for Qin Lin to easily find the problem?

Like Qin Lin earlier, when he checked the identity, time of death, and cause of death of the deceased, although his methods were extremely exquisite, it was not that he did not find any evidence? Until now, it can only be proved that Liu Liangfu was burned to death!

"Let him check, the old man forgives him for not finding anything, hum ......" Yang Zhao had a gloomy face, and said: "The old man is a heavy border defense officer, and he is a member of the imperial court, and he can't find any evidence, so dare he slander the old man?" ”

Lu Fatzi was very excited, thinking that the dawn of solving the case was just around the corner, but when he saw the pile of burned rubble, he couldn't help but scratch his head: "Brother Qin, even if Liu Liangfu left any death information, it would have been burned to ashes long ago, how can we get it." ”

"Bold, careful, rigorous and thorough, there is no clever way to handle the case, it's just these eight words," Qin Lin said, slowly looking at the pile of rubble.

Liu Liangfu is certainly not as cruel and vicious as Zhao Shichen, but he is also an extremely cunning Shaoxing master, if he knew that he would die, would he be willing to go on the road?

It stands to reason that he will definitely find a way to leave something of value behind to help the detectives avenge himself.

Qin Lin thought for a while, and ordered the captains of the pro-soldier school to clean up the rubble, and leave the roof bricks and tiles that were smashed down, and move them to the side and pile them up, but the various furnishings in the room should not be moved, and they should be put in their place.

At this time, the stagnant water also flowed away, and the clean-up work was easier, and the captains carefully carried various things with their hands and cleaned up the scene according to Qin Lin's command.

It didn't take long for the scene to be cleared out, and the bricks and tiles were removed, leaving only the remnants and fragments of tables, chairs, cages, cups and plates, washbasins, etc., placed on the ground according to their original positions.

Qin Lin asked the captain who found the corpse again, and combined with his own memory, he took out lime from the forensic kit and sprinkled it on the ground.

What is this for, take lime to reduce the corpse poison?

Of course not, the lime flowed out of Qin Lin's fingers, and when it was sprinkled on the ground, it became the outline of the human body, and after a while, a person curled up on the ground with his hands and feet on his side appeared, and the head, hands and feet and other parts were clearly distinguishable.

"It's exactly the same, that's what the corpse looks like when you find it!" The pro-soldier lieutenant shouted.

It turned out that Qin Lin used lime to draw the posture of Liu Liangfu's corpse, and combined with the remnants and fragments of various indoor furnishings on the ground, he restored the situation in the house before the fire.

Everyone looked at it, and saw that the table was stacked with fragments of wine glasses and rice bowls, which meant that there was a plate that was originally placed on the table and fell on the ground next to it, very close to the head of Liu Liangfu's body, and the washbasin was overlapped on the ashes of the wooden shelf, of course, it was originally resting on the shelf...... Qin Lin asked Xu Wenchang to think carefully about what was different from when he and Liu Liangfu were drinking and eating.

"Like, nothing has changed?" Xu Wenchang grabbed his gray hair: "Except for the broken plate......"
