In the morgue, Xu Lang saw Shen Jun's body, which had no other external injuries except for his head.

The head of the corpse has been smashed with a blunt object, in a common saying, that is, his own mother who beat him doesn't know it, the head of the corpse has been hit many times, resulting in skull deformation, craniocerebral injury, brain hemorrhage to death, the human head is the hardest place in the human body, and the bone density is also the largest place, but the back of Shen Jun's head is deep, the scalp is falling off, and the face is even more smashed flesh and blood.

Xu Lang has seen Shen Jun's files, which clearly record Shen Jun's past in the past few decades, Shen Jun has been detained three or four times before and after, and fined more than a dozen times, which can be said to be a frequent visitor to the police station.

Xu Lang has also seen Shen Jun's photos, people look very ordinary, pointy-eared monkey gills, small eyes, small noses, thin lips, in the photo, Shen Jun's small eyes are shining, exuding a shrewd light, although Shen Jun is a small mistake, but he has not made any big mistakes, at most he likes to do some things like stealing, but such a person, why would anyone put him to death?

Could it really be that someone is interested in getting rich? But at the scene of the death, the police searched a wallet from Shen Jun, which contained more than 2,000 yuan in cash, as well as a mobile phone, and the mobile phone still had electricity. What's more, since Shen Jun has a mobile phone on him, why didn't he take out his mobile phone to make a call when he was locked up with Zhu Hongfang and Yang Xuewen? Is it because there is no signal? Impossible, the abandoned factory is not built in the wilderness, but in the city, although it is close to the suburbs, but the mobile phone cannot have no signal, is it because the mobile phone is in arrears? It is also impossible, when the police investigated Shen Jun, they went to the communication company to investigate the phone card in Shen Jun's name, and the data showed that the mobile phone card in Shen Jun's mobile phone still cost more than 100 yuan, and it was only recharged for a short time, so it is impossible for the mobile phone to be down and in arrears, so why didn't Shen Jun take out his mobile phone to call the police or call relatives and friends for help?

Could it be that he killed someone out of love? This is also impossible, in the investigation of Shen Jun, it was found that although Shen Jun usually has the habit of petty theft, and occasionally goes to some red light districts, but he has not had a close relationship with other women except for his wife, of course, this is not that Shen Jun does not want to, men, who doesn't want to be at home is the red flag does not fall, and the colorful flags are fluttering outside, but, if a man wants to do this, he must have capital, money and power, a house and a car, Shen Jun has a house, but it is an old house, and now with the rapid development of the economy, it is no longer worth anything, rich? Shen Jun's monthly salary is more than 2,000 points, if you want to get more, you have to work overtime, but Shen Jun is a person who is not very able to bear hardships and stand hard work, if he can bear hardships and stand hard work, then he will not steal chickens and dogs, powerful? Think about it and think it's impossible, have a car? Shen Jun has no other means of transportation except an old motorcycle, and this motorcycle is still second-hand, so it is even less valuable, no money and no power, there is a house and no car, which woman can look up to this man in his forties?

Is it a vendetta killing? This point is not sure for the time being, Shen Jun's misbehavior on weekdays naturally aroused the dissatisfaction of some people, and the leaders and colleagues of his company are not used to seeing it on weekdays, but if any of them have a holiday with him, there must be a lot, but if any of these people kill people because of this holiday, it is not enough, but in addition to leading colleagues, Shen Jun actually has no friends, and he can't kill people for such a thief.

Since it is not a vendetta, nor a love killing, nor is it a murder for money, will it be a murder of passion? If it is a murder of passion, then Zhu Hongfang and Yang Xuewen are much more suspicious, and there are several possibilities.

First, they all came for those boxes of highly home-brewed liquor, the goods are just a little, everyone wants to buy some, could it be because when buying liquor, the three of them had a conflict and killed Shen Jun after a mistake?

Second, the three of them didn't know each other at first, they came to the abandoned factory and were stunned and locked in the warehouse, so could it be that after they woke up, they found themselves locked inside, suspicious of each other, blamed each other, and then escalated into a physical altercation, inadvertently killing Shen Jun?

Third, that is, one of the two people, Zhu Hongfang and Yang Xuewen, is lying, and one of the two of them knows Shen Jun, but for some reason, they pretend not to know each other in the warehouse, but they have a direct contradiction, so Zhu Hongfang or Yang Xuewen killed Shen Jun while Shen Jun and one of them were asleep?

With these three guesses, then it needs to be verified one by one, first of all, the first guess, if it is said that it is because of the high degree of home-brewed liquor, since it is because of the high degree of liquor, then in addition to Shen Jun and the three of them in the warehouse, there should be a fourth person present, and this person is selling wine, but the scene did not find the fourth person to exist, if there is no fourth person, then could it be that one of the three of them is selling wine? And Shen Jun happens to be the one who sells wine?

If you think so, it is also very possible, because Zhu Hongfang and Yang Xuewen both received the note, although the note was not found, but according to the police investigation, there is indeed the existence of this note, and Shen Jun's body did not have the note, and there was no trace of the note burned at the scene, and no note was found at the scene, if this is the case, then Shen Jun is likely to be the one who sent the note to Zhu Hongfang and Yang Xuewen, and Shen Jun is the one who sells wine.

Could it be that when the three of them were trading, they had a conflict because of the uneven buying and selling and killed Shen Jun by mistake? After they found out that Shen Jun was dead, they were afraid of being punished by the law, so they smashed Shen Jun's face with bricks, hoping that no one would be able to recognize Shen Jun after the police found the body.

If this is really the case, then there is a lack of evidence, that is, Zhu Hongfang and Yang Xuewen's mouths of the boxes of high-height home liquor, when the police investigated the scene of the crime, they searched the abandoned factory back and forth, up and down, inside and out, and went to the homes of Zhu Hongfang, Yang Xuewen and the deceased Shen Jun, but did not find those boxes of liquor.

No liquor was found, so the possibility of killing a person by mistake because of a few cases of liquor needs to be discussed.

After thinking about the first possibility, Xu Lang went to deliberate on the second possibility, will there be a contradiction caused by mutual accusations and mutual suspicion, Zhu Hongfang and Yang Xuewen accidentally killed Shen Jun when the conflict occurred? This possibility is very high, because of suspicion and accusation and anger murder is not unheard of in criminal cases, although this kind of case occurs, but it is also a minority, but, the question is, which of the two people, Zhu Hongfang and Yang Xuewen, accidentally killed Shen Jun? It's not certain.

As for the third possibility, Xu Lang did not verify it again, because these three possibilities were established under the premise that there was no fourth person present, and Shen Jun was killed by Zhu Hongfang and Yang Xuewen, if the fourth one was present, or Shen Jun was not killed by the two of them, then these three possibilities are not valid, if you want to verify these guesses, then the easiest way is to meet the two suspects, Zhu Hongfang and Yang Xuewen.

After thinking about this, Xu Lang was about to leave the morgue, and at this moment, Ye Xuefei stopped Xu Lang and told Xu Lang a piece of news, that is, when she was doing an autopsy on Shen Jun's body, she found that there was chloroform in the deceased's body.

Hearing the name chloroform, Xu Lang's heart moved, and he remembered one thing, that is, whether it was when Ning Yanran went to Xu Lang's house to find Xu Lang and narrated the case to Xu Lang, or when Xu Lang came to the Public Security Bureau to check the file, he found a detail, that is, whether it was Zhu Hongfang or Yang Xuewen, when they entered the abandoned factory, they were attacked from behind, covered their mouths and noses with towels and other things, and then fell into a coma, and after they woke up in the warehouse, It didn't take long for him to smell a strange smell again, and then he passed out again.

Xu Lang couldn't figure out how Zhu Hongfang and the three of them were easily subdued, and now that he heard that the existence of chloroform was found in the body of the deceased, many questions could be explained.

The scientific name of chloroform, also known as chloroform, is a colorless and transparent liquid with a special odor and volatile. Sweet, heavy, high refraction, non-combustible, with anesthetic effect, this kind of thing, as long as a person inhales a little, it is easy to be unconscious, with this kind of thing, then it means that whether it is Zhu Hongfang, or Yang Xuewen, and the deceased Shen Jun are all stunned by people with this kind of thing, which can prove one thing, if Zhu Hongfang and Yang Xuewen did not lie, then there must be a fourth existence at the scene, and this person is the murderer of Shen Jun.

Because of the appearance of chloroform, it proves that there is a fourth person at the scene, but how did this fourth person kill Shen Jun?

If it is just a one-way secret room, then after the fourth person stunned Zhu Hong and released the three of them for the second time, he could open the door from the outside, enter the warehouse, kill Shen Jun, and then walk out of the scene, lock the door of the warehouse from the outside, and then leave, but, according to Zhu Hongfang and Yang Xuewen's explanation, after they woke up for the second time, they found that the door of the warehouse was locked from the outside, and they were worried that they would not be able to stay up and fall asleep in the warehouse, so they locked the door from the inside of the warehouse, so The original one-way secret room has become a two-way secret room, if the fourth person is outside, then he can only open the lock outside, or can't get in, since he can't get in, it is impossible to kill Shen Jun, if the fourth person is in the warehouse, then how did he leave the warehouse after killing Shen Jun? Can this person still pass through the wall? No, how could anyone be able to get out of a two-way chamber?

Another point is that if there is a fourth person at the scene, then why did Liu Maocai and Zhu Hongfang's wife Qin Yumei only find the deceased Shen Jun, as well as Zhu Hongfang and Yang Xuewen after they arrived at the scene? Moreover, when Zhu Hongfang and Yang Xuewen were brought to the Public Security Bureau for interrogation, they insisted that there were only the two of them and the deceased Shen Jun in the warehouse at the scene, and there was no fourth person in the total of three people.

Could it be that the two of them were deliberately trying to cover for the fourth person? This is impossible, this is not ancient, for the sake of a righteous word to take the blame for others, there is only one life, ants are still greedy for life, let alone people? Murder is not a trivial crime, although the state is cautious about the death penalty, if they really admit that they killed Shen Jun, even if they will not be sentenced to death, they will be sentenced to life imprisonment, and the minimum is 18 years in prison.

Zhu Hongfang and Yang Xuewen are both almost fifty people this year, as the so-called fifty knows the destiny of heaven, at this age, they have already experienced too many winds and waves, what kind of scene have they never seen, they naturally know the priority of the matter, they have no need to admit to killing for an irrelevant person, not to mention, they did not admit that they killed someone, but identified the other party as a murderer.

If the mystery of this two-way closed room murder case cannot be solved, then the case cannot be solved, so Xu Lang decided to meet Zhu Hongfang and Yang Xuewen in person for a while.

Under Ning Yanran's arrangement, Zhu Hongfang was interrogated again, Xu Lang was in charge of the interrogation, and Ning Yanran was in charge of recording.

Xu Lang sat behind the interrogation table in the No. 1 interrogation room, in this not very large room, Xu Lang didn't know how many prisoners he had interrogated and how many major and important cases he had solved, but none of them would be as incomprehensible as this case.

Zhu Hongfang is forty-eight years old this year, Zhu Hongfang is one meter seventy-two tall, belongs to the kind of medium height, Zhu Hongfang's body is slightly fat, because he works in a mechanical processing factory, although he has not been exposed to the sun all year round, but Zhu Hongfang's skin is still relatively dark, unlike other people who work in the factory, the skin shows a sickly paleness, and when Zhu Hongfang was brought into the No. 1 interrogation room, Xu Lang smelled a faint smell of engine oil, although the taste was relatively light, but in this small interrogation room, It's still easy to smell.

This kind of smell is the kind of perennial machine tool operation in the workshop, dealing with steel and oil, lubricating oil and the like every day, after a long time, there is naturally this smell on the body, and Zhu Hongfang is still an old worker in the machinery processing factory, he has been working in the factory for more than 20 years, and the smell on his body is naturally heavier, which is the same as people who like to smoke, the kind of old smoking gun in the general countryside who likes to smoke dry cigarettes, when dealing with this kind of person, only close to them, can smell the smell of smoke on their bodies.

After Zhu Hongfang was brought in, Xu Lang didn't talk nonsense with him, and asked directly to the point: "Did you kill Shen Jun?" ”

As soon as Xu Lang's words came out, Zhu Hongfang had a bitter face, and shouted injustice: "Two police officers, two police uncles, and police aunts, I really didn't kill Shen Jun, it was Yang Xuewen who killed him, and it has nothing to do with me." ”

"You said that Shen Jun was not killed by you, but by Yang Xuewen? Then what evidence do you have to prove that Shen Jun was not killed by you, and what evidence do you have to prove that Shen Jun was killed by Yang Xuewen? Xu Lang looked at Zhu Hong and asked expressionlessly.

Zhu Hongfang, who was already crying and mourning, after listening to Xu Lang's question, his face became more and more difficult to look at, he looked at Xu Lang, sighed, and said slowly: "Uncle police officer, I have no evidence to prove that I didn't kill the person, but I really didn't kill anyone, but I know that the person must have been killed by Yang Xuewen." ”

Xu Lang and Ning Yanran glanced at each other, and then, Xu Lang continued to ask, "Then what evidence do you have to prove that Yang Xuewen killed the person?" ”

"At that time, the door of the warehouse was locked from the outside, and there were only three of us in the warehouse, and now that Shen Jun is dead, I am sure that I didn't kill anyone, so who else can kill him except Yang Xuewen killed Shen Jun? It can't be a ghost, right? ”

When Zhu Hongfang said this, his tone was very firm, obviously in his heart, the scene was a two-way secret room, three people, Shen Jun died, he didn't kill anyone, and outsiders couldn't enter, so the one who could kill Shen Jun must be Yang Xuewen.

After listening to Zhu Hongfang say this, Xu Lang can be sure that Zhu Hongfang said that he did not kill anyone, this, Xu Lang believes, of course, this is just Xu Lang's conclusion based on his years of experience in solving cases from the police, although Xu Lang believes that Zhu Hongfang did not kill anyone, but this is only Xu Lang's belief, and it cannot be used as evidence to prove that Zhu Hongfang did not kill anyone, so after Xu Lang pondered, he said to Zhu Hongfang: "You tell the events of the day again." ”

"Okay, okay, okay, I said, I said, this police uncle, you want to return my innocence."

Looking at a person who can be his father calling his uncle, Xu Lang felt uncomfortable and uncomfortable.

The next time passed minute by minute in Zhu Hongfang's narration.

Zhu Hongfang put himself after work, how he saw the note at the door of his house, how he went home and told his wife Qin Yumei, how he went to the abandoned factory, how he was attacked from behind and stunned, how he woke up in the warehouse, how he fell asleep again, how he was rescued from the warehouse, and how he came to the Public Security Bureau, 1510, the original explanation.

After listening to Zhu Hongfang's story, Xu Lang fell into deep thought, because what Zhu Hongfang said in front of him now was not much different from the dossier he had read before, so it can be seen that if Zhu Hongfang is not a person with outstanding acting skills, then what he said must be the truth.

After Xu Lang muttered for a while, he whispered a few words to Ning Yanran, and then the two of them walked out of the interrogation room and left Zhu Hong alone in the interrogation room.
