The rate of decay of a corpse is greatly affected by the ambient temperature, the cause of death, and the individual's constitution. In the human body, because the ileocecal part is prone to stagnation of feces, the decay occurs earlier after death, and more hydrogen sulfide is produced, so the corpse green first appears in the right lower abdomen. Corpse green usually begins to appear at the end of the first day and night, and then gradually expands, spreading to the entire abdomen and then to the whole body. Generally speaking, corpses decompose most rapidly in summer, and corpse green begins to appear in the right lower abdomen, more than 24 hours after death. If the corpse is a giant, it has been dead for more than 3 days.

At this time, the weather was hot and dry, Li You's body had been slightly decomposed, and his whole body had already appeared corpse green, and the whole body began to swell and swell, making it difficult to identify his appearance before his death. This phenomenon is known as the corrupt giant view. Wearing rubber gloves, everyone worked together to put Li You's body into a body bag and put it in the car, and Shao Dong drove Wu Wei back in order to conduct further autopsy on the body.

When I went out, I saw that the crowd of onlookers had almost dispersed, and Lu Zhiyong didn't leave, just sat on the grass next to the road, and saw everyone coming out, Lu Zhiyong got up and walked over.

Li Tie helped carry the corpse to the car, and said to Lu Zhiyong: "Secretary Lu, it just so happens that you haven't left, and I want to trouble you, arrange for the village cadres to guard the scene 24 hours a day, our investigation is not over yet, I will find you to understand the situation later." ”

Lu Zhiyong said politely: "Okay, Officer Li, I'll arrange people, you guys are busy first, I'll wait for you at home, I'll live in front of the first one to turn left." I've got a meal at home, and you'll come and eat later. ”

Li Tie took Wang Bo to carefully search the dirt ground around the courtyard, because there were traces of climbing on the courtyard wall, the focus of the two was set here, and then expanded the scope of the search outside the courtyard.

There are a lot of onlookers, and there are a lot of messy footprints left on the road outside the house, after careful comparison, the two of them found a lot of corrugated footprints on the dirt road outside the courtyard, although they are incomplete, but they are basically the same as the complete three-dimensional footprints in the courtyard.

Wang Bo analyzed: "Master, you see that these footprints are messy, and it is difficult to distinguish whether they are left by the crowd of onlookers at the scene or by the suspects. ”

Li Tie said: "The footprints are relatively clear, and I think it is very likely that they were left by the onlookers at the scene, that is, the murderer is likely to be among the onlookers at the scene." ”

"Let's compare them one by one?" Wang Bo asked.

"The murderer is a person from the village, we have to hurry up, go, now go to Secretary Lu's house, and let Secretary Lu take us to investigate. Li Tie said.

The two came to Lu Zhiyong's house, Lu Zhiyong sat and waited in front of the door, Lu Zhiyong's home is an ordinary brick house with a single courtyard, and there is no fence, but simply a fence around the house with tree branches.

Seeing the two coming, Lu Zhiyong said politely: "Hurry up and enter the house, I haven't eaten for a day, I asked my daughter-in-law to make some homely meals, and the two police officers can eat as much as they want." ”

Li Tie said: "Then thank you, Secretary Lu." ”

Lu Zhiyong let the two into the house, and after sitting down, "Two police officers, drink some water first." I asked my daughter-in-law to serve the food. Lu Zhiyong poured two glasses of water and greeted warmly.

"That's the case, Secretary Lu, there are a lot of onlookers at the scene today, can you take us to visit door to door, especially the young adults who are watching at the scene in the afternoon, we have to investigate. Li Tie said.

"Okay, after dinner, I'll take you there. Lu Zhiyong said.

As he spoke, the dishes were served on the table, all of which were specialties of the countryside, a pot of roasted chicken, a pot of braised pork, and two cold dishes. Lu Zhiyong also took out a bottle of liquor.

Li Tie said: "I won't drink the wine, we still have work to do." ”

"Okay, then you eat more, the chickens and pork are all raised by yourself, they are all green food, and the vegetables are also grown in the ground, without chemical fertilizer. Lu Zhiyong greeted.

Li Tie was not polite, and motioned to Wang Bo to eat, he hadn't eaten for a day, and this kind of domestic chicken was indeed very fragrant, and both of them had eaten a lot.

Lu Zhiyong was very happy, and kept being polite and asked the two to eat more.

After eating, Li Tie took out 100 yuan from his pocket and put it on the table, Lu Zhiyong was stunned, got up and said angrily: "Officer Li, what are you doing here?"

Li Tie smiled and said: "Sit down, you sit down first and listen to me, we police have a system, you must accept this money, otherwise we will violate discipline." ”

"Aren't you scolding me? Eat some homely food, can I still charge you money?" Lu Zhiyong said anxiously.

"Secretary Lu, you have to understand us, we can't do anything that violates discipline. You're welcome, we're pressed for time, so you can take us to visit the crowd quickly. Li Tie said.

"Oh well. Lu Zhiyong said helplessly.

Lu Zhiyong pointed the way, and the three of them went door-to-door to visit and investigate, the focus of the visit was what Li You did before he died, who he met, whether he had been in love or who he had a conflict with, etc., the focus of the investigation was on the households with young adults at home, and the young and middle-aged men between the ages of 20 and 45 were compared one by one, mainly comparing the shoes on the feet and the shoes worn at home.

In this almost isolated village, the people are relatively simple, and the occurrence of such a case makes the residents of the whole village feel uneasy, so most of the residents do not sleep, and most of the villagers are visiting the door, talking about the murder case and their own conjectures.

Lu Zhiyong is the secretary of the village, in the eyes of the villagers is a great official, Lu Zhiyong took the lead in knocking on the door, introduced, with the cooperation of Lu Zhiyong, the investigation and visit was very smooth, basically every family can cooperate well.

In the investigation, it was found that this corrugated footprint, from the military liberation shoes that have been distributed by the army, was very popular in the early days of China's liberation, and the factory that produced the liberation shoes has been selling to the public, this kind of shoes in today's county, few people have worn them, because in the eyes of the people in the city, this kind of shoes has become outdated, and very old-fashioned.

But in Dawang Village, many people still wear this kind of shoes, because this kind of rubber-soled canvas shoes are cheap and durable, and they can be worn in the other three seasons except for the very cold winter.

The 42-yard liberation shoes belong to the public size, there are many villagers who are 42-yard shoes, and most of the sources of the liberation shoes in the village are bought at the temple fair in the neighboring village, 12 yuan a pair, it is reported that there are three shops selling this kind of shoes at the temple fair. It is obviously very difficult to check from the footprints of the site.

After a visit in the middle of the night, there are several clues that Li Tie has paid attention to, according to the neighbors who know Li You, Li You is more attentive, usually only when he harvests wheat and goes home during the New Year, but because he earns some money by working outside, and Li You is handsome and chic, so the young women in the village appreciate him more, in the past few years, Li You has talked about four or five girlfriends, all of whom are girls in the village.

In the past two years, Li You has had an affair with a woman named Huahua, and Huahua's nominal boyfriend is called Qian Binbin.

In Dawang Village, where the people are simple, Huahua's behavior is despised by the elderly people in the village, so many people in the village regard these things as after-dinner conversations.

I learned from the mouths of various villagers: Huahua's boyfriend Qian Binbin's family situation is very poor, there is only one elderly father in the family who is bedridden, Qian Binbin gave up his job outside and took care of his father at home, and his father took medicine all the year round.

And Li You's family are all working outside, with a good income, and they usually maintain an underground relationship with Huahua, which can meet Huahua's expenses and daily expenses.

Through these circumstances, Li Tie analyzed that the motive for the murder may be jealousy, and the direction of the investigation should be mainly love killing and vendetta killing, supplemented by financial killing.

After the first round of key visits, Lu Zhiyong strongly asked Li Tie and Wang Bo to rest at their homes, Li Tie thought about it and agreed.

When he got up early the next morning, Li Tie left 100 yuan at the head of the bed, and had a simple meal at Lu Zhiyong's house, and Shao Dong called. Inform me that you have returned to Dawang Village.

After the three met, Wu Wei's phone also called.

"Team Li, the autopsy results are out, and the situation is consistent with what we expected, Li You's death was a death from hemorrhagic shock caused by the complete severance of the left common carotid artery and the left internal jugular vein. Judging by the contents of the deceased's stomach, the time of death was on the night of the 26th, and I analyzed the road with Dongzi, and Dongzi said that he would go home at night and make a summary, and let him tell you about it later. ”

"Well, martial arts scholar, you have worked hard. ”

"You're kind to Team Li, that's it, I'll contact you again if you have something. ”

Shao Dong took out a notebook from his arms and said: " Judging from the knife on the quilt in the bedroom, the deceased should have been attacked in a sound sleep or completely defenseless situation, and was stabbed three times in the neck, and there were two murderers, and one of them had a pre-wrapped cloth or socks on his feet, and the two murderers climbed over the wall to the courtyard, and then entered the bedroom through the window, and killed the suspect, which was premeditated, and had a certain psychological quality and anti-reconnaissance experience, and the deceased did not die immediately after being stabbed three times in his body, but got out of bed, did not have time to put on shoes, and chased the murderer barefootThe murderer pulled out the bolt from the gate, and then walked away, and the deceased chased him to the courtyard, where he fell to the ground and died due to excessive blood loss and physical exhaustion. ”

Li Tie listened and pondered, and said: "We worked for most of the night last night, and got a few clues, looking for the suspect from the footprints, obviously it doesn't work, this corrugated footprint comes from liberation shoes, because hundreds of young and middle-aged men in the village wear this kind of liberation shoes, and many of them have size 42 feet." ”

Wang Bo added: "We got clues, Li Goudan has a lover named Huahua, Huahua has a boyfriend named Qian Binbin, this Qian Binbin's father is bedridden all the year round, and Qian Binbin gave up his job in order to take care of his father, so the family conditions are very poor, and he usually relies on Huahua to help, and Li Goudan has a lot of savings, and he usually spends money less, so my master plans to start from this aspect." ”

"Yes, now we will go to Qian Binbin's residence to find him. Li Tie said.
