July has passed, August is coming, the hottest time of the year has arrived, many companies have successively released high temperature holidays, and the police responsible for investigating the murder of Chen Qiumin are still investigating in an orderly manner.

The day after Xu Lang returned from Chenjiahe, Xu Lang gave Fan Yang a few days off, asking her to hand over the trace inspection work to others and let her go back to her hometown, that is, Changyang City.

At this time, Fan Yang was given a holiday, naturally not to let him go back to play or travel, but to let him go back to Changyang City, investigate the case of Chen Qiumin's parents being killed three years ago, and retrieve relevant files to see if Chen Jianjun and his wife died accidentally, and Chen Wang, who followed Chen Jianjun and his wife to Changyang City to work, to see what kind of work they were engaged in in Changyang City.

Since it is not possible to get useful clues from Hengtong County for the time being, it is necessary to investigate in a different direction.

When investigating the murder of Chen Qiumin, Chen Wang and others were discovered, and when the police were preparing to investigate Chen Wang, Chen Wang was also killed.

The next day, Ding Haoqiong went to the department that mainly investigates the smuggling and trafficking of wild animals, and asked the relevant departments to assist in the investigation, mainly to investigate the cases of wildlife smuggling and trafficking in and around S City in the past three years, and see if there are any clues that can be found in these case files, which are related to Chen Wang or Hengtong County.

As for Luo Jiayan, she is still responsible for visiting and investigating the information of Chen Zhen and others, mainly focusing on Chen Zhen, in addition, Xu Lang asked Luo Jiayan to contact Situ Yinuo's parents in Zhouhua City, and asked where Situ Yinuo is now, if she really studied abroad, see if she can contact the other party, if she did not study abroad, ask where she is now? Can you meet and ask about Chen Zhen?

Qin Mingyue and assistant Ren Xue are still dissecting and analyzing the bodies of Chen Wang and Chen Qiumin, while Lu Xing is providing technical support at any time, as for Xu Lang himself, he really wants to go back to Hengtong County to understand the situation, but, according to the information currently held by the police, Hengtong County and Chen Jiahe are not as simple as the police knew before, if Chen Guodong and others are really involved in the smuggling and trafficking of wild animals, then, Xu Lang will go again at this time, it is undoubtedly a surprise, he needs to find a way to open a new breakthrough from other places.

When a person disappears or disappears, it is actually difficult to find the other person by relying on the strength of the individual, but it is much easier to find a person in front of the state machine.

In the next few days, the investigation of Chen Qiumin and others gradually summed up.

First of all, the autopsy results on Qin Mingyue's side came out.

According to the autopsy, Chen Wang was attacked from behind and hit the back of his head with a blunt object, resulting in cranial hemorrhage and death.

There is an obvious dent mark on the back of Chen Wang's head, and part of the scalp and hair at the wound have been torn and peeled off, in the wound, Qin Mingyue found some rocks and sand, and compared and analyzed the corpse and sand collected by Fan Yang from the scene, the material structure of the two is the same, and the wound is irregular in shape, so it is judged that the deceased Chen Wang was stoned to death with a blunt instrument such as a stone.

Although the cause of Chen Wang's death was determined, however, no bloody stones or other items were found at the scene, and the comrades of the Chengnan Police Station and the Chengnan Criminal Investigation Detachment conducted a detailed search near the scene when they sealed and locked the scene, and even dispatched police dogs, but the murder weapon was still not found.

Fortunately, the weather has been hot recently, there has been no rain, and the sea is also calm, after the frogman continued to dive work, finally found a few similar stones on the bottom of the sea not far from the pier, and after these stones were salvaged, they were immediately sent to CSY, handed over to Qin Mingyue, Qin Mingyue compared the shape of the stone with the wound of the deceased, and found that one of the stones was very consistent with the wound of the deceased, which shows that the murder weapon was found.

Although the murder weapon was found, the blood stains of the deceased on the stone were long gone under the washing of the seawater, and a group of fingerprints were found on the stone, but the fingerprints were very vague and did not have much comparison value, which means that although the murder weapon was found, it was still not feasible to find the suspect from the murder weapon.

In addition to the fatal wound on the back of the head of the deceased Chen Wang, there was also a knife wound on his back, according to the autopsy results, this knife wound was caused by the deceased before his death, the wound was very deep, according to the shape of the wound should be a fruit knife or a dagger and other controlled knives, however, this wound is not a fatal injury, the perpetrator obviously does not know much about the human body structure, this knife did not pierce the heart of the deceased, but pierced the lung lobe of the deceased, this kind of wound, as long as the rescue is timely, the deceased may survive.

No knives were also found at the scene, and the frogman was salvaging in the sea near the pier and did not find the murder weapon, so it is likely that the murder weapon was taken away by the murderer.

According to Qin Mingyue's autopsy results, the knife wound on the deceased's back should have occurred before the head wound, however, according to the deceased's wound

Judging from the shape and physiological reaction, the time of formation of the two wounds is very close, and someone should have attacked Chen Wang from behind with a knife, but because the knife did not stab the deceased's heart, Chen Wang did not die on the spot, and the murderer took materials on the spot, picked up a stone, and smashed it on the deceased's head, with great force, directly smashed the back of the deceased's head into the depression, causing Chen Wang to die directly.

Qin Mingyue analyzed the two wounds and found that there should be two perpetrators, one of whom was not tall and lacked strength, it could be a short and thin man, or it could be a woman, the latter was more likely, and this short man was the one who stabbed the deceased in the back with a knife, and the other person should be about the same height as the deceased, judging from the wound on the back of the deceased's head, the perpetrator must be a man with great strength.

The time of death of the deceased was the evening of July 31, to be precise, around 4 o'clock in the morning of August 1, and on July 31, Xu Lang and Luo Jiayan were investigating Chen Qiumin's past in Hengtong County.

The cause of death has been determined, and the time of death has been determined, but what is the murderer's motive for committing the crime?

At the scene of the crime, in addition to the body of the deceased, only the bloody banknotes, the mobile phone carried by the deceased were missing, and although the deceased's wallet was still there, and some of the cash placed in it was still there, but the bank cards and ID cards in the wallet and other documents that could prove the identity of the deceased were all gone, and it should be that the murderer was taken away by the murderer after committing the crime.

Previously, Xu Lang and their analysis that Chen Wang may have learned the news of Chen Qiumin's murder and was ready to sneak in advance and abscond, if this is the case, the deceased should have brought some luggage when he absconded, and the luggage may not be much, but some necessary things will still be brought, such as a change of clothes and the like, but the scene has not been found.

The police officers who were responsible for searching the scene found the ashes left after the burning of an object about 800 meters away from the crime scene, collected the ashes, and brought them back for technical analysis and testing, and found that these ashes were traces left after some clothes were burned, and among the ashes, the police found metal zippers, and a small part of the clothes that were not completely burned, and on the clothes, the police found some biological samples, after technical comparison, It was found that these biological samples matched the DNA of the deceased Chen Wang, that is, the clothes were actually Chen Wang's own.

At this point in the investigation of the case, the fact that Chen Wang was killed has been undoubtedly determined, but it is not clear who killed him and why he killed him.

However, judging from the posture of the deceased at the scene of the crime, as well as the time when the deceased was killed, it is likely that someone killed someone, or killed someone because of the passion caused by the dispute, whether it was premeditated murder or improvised, in short, the murderer was two people, and they knew the deceased, which is certain.

After Xu Lang got these information and clues, he had a new question in his heart.

Chen Wang's murder, whether it was a premeditated murder or an impromptu intention, since they chose to kill someone, and, after killing someone, they also took away the deceased's ID card and bank card and other documents that could prove the identity of the deceased, threw the murder weapon into the sea, and in addition, burned the luggage of the deceased, since they had time to do this, why didn't they just throw the body into the sea after killing someone? In this way, it is likely that the body of the deceased will not be found near the pier, and will definitely be washed away by the sea to other places, and in this way, the body will certainly not be found by the police so quickly, and the identity of the deceased will not be found all at once.

Taking away the deceased's ID card, bank card and other items was to prevent the police from immediately identifying the deceased, burning the deceased's luggage and clothes, and also for this purpose, throwing the murder weapon into the sea and taking away the bloodstained knives, so as not to let the police find them according to these murder weapons.

This is what Xu Lang can't figure out the most in the murder case of Chen Wang.

Could it be that he was so nervous about killing someone that he forgot to dispose of the body?

Xu Lang felt that it was unlikely, since the murderer could still think of taking away the deceased's identity certificate after killing someone, this shows that the murderer has a certain sense of anti-reconnaissance, in addition, judging from the photos taken at the scene of the crime, the body of the deceased Chen Wang was lying on the dock, and not far from his corpse, he could directly kick his body into the sea.

Isn't this a temporary murder of passion, but a premeditated murder?

If that's the case, then after killing someone, disposing of the corpse is the most important thing.

Thinking of this, Xu Lang felt that there might be another situation.

Regardless of whether the murderer was improvised or premeditated murder, in short, after killing Chen Wang, they took away the ID card and other items from him, and then took the deceased's luggage and took it to a place far away from the body to be incinerated, and after they did this, they must have wanted to dispose of the corpse after dealing with these things, but when they were about to dispose of the corpse, something happened, so they did not have time to dispose of the corpse and left in a hurry

This doubt can be explained.

If Xu Lang's assumption is true, then, after Chen Wang was killed, something must have happened at the scene, for example, when they burned Chen Wang's clothes, they were discovered, in order not to expose themselves, they had to choose to flee the scene, or it could be that they received a temporary call after finishing the case, asking them to hurry up and leave, or it could be that they really forgot to dispose of the body, in short, according to this suspicion, an investigation can be conducted.

So, Xu Lang found Lai Pi and asked him to go to the south of the city to conduct a detailed visit and investigation, especially to those wanderers and scavengers who have lived near the dock for a long time, to see if they saw anything on the night of the crime, and if they really saw something, perhaps, this question can be solved.

After the investigation of Chen Wang's murder case progressed, news also came from Luo Jiayan, who was in charge of investigating Chen Zhen.

According to them, after Situ Yinuo graduated from university, they did send her to study abroad for the sake of their daughter's future, and she has been abroad all these years and has never returned.

When Luo Jiayan asked them how long Situ Yinuo hadn't contacted them, they reflected a very important situation, that is, Situ Yinuo had never contacted them by phone since he studied abroad, and occasionally the contact was through email or text message, which made them feel very strange, but Situ Yinuo's parents were usually very busy with work and had no time to think about this.

According to them, Situ Yinuo is their only child, because they are only daughters, they have been doting on Situ Yinuo since they were children, as long as their daughter wants, they will try to satisfy it, and they are usually very busy with work and have no time to take care of their daughter, resulting in the relationship between Situ Yinuo and them, in fact, it is very tense, especially when Situ Yinuo was in college, his father was exposed to raising his lover outside, which led to a family war, although the matter was finally resolved, and his parents did not divorce, but, Situ Yinuo has always been obsessed with this matter, and his relationship with his parents is even worse, and he is almost unwilling to communicate with them, and they have no good way to do this, after all, Situ Yinuo has grown up, and many things have their own ideas, and they are not good at intervening too much.

Situ Yinuo studied abroad two years ago, and there is still a year before she can return to China, and her parents want to wait for Situ Yinuo to return to China, and then arrange for him to enter his own company and start to take over the company's affairs, of course, if Situ Yinuo is unwilling to take over the company's industry and wants to start his own business, they also support it, and after they received Luo Jiayan's call, they felt very puzzled, thinking that something happened to Situ Yinuo.

When Luo Jiayan reported the situation to Xu Lang, Xu Lang immediately sensed that something was wrong, and immediately asked Luo Jiayan to contact Situ Yinuo's school abroad, however, the results given by the school surprised Xu Lang and them.

According to the school, there is no international student named Situ Yinuo from Huaxia in their school, although there are many international students from Huaxia in their school, but there is indeed no one named Situ Yinuo.

In other words, after Situ Yinuo graduated, her parents arranged for her to study abroad, but Situ Yinuo did not go.

In order to determine the authenticity of this situation, Luo Jiayan contacted the exit department again and retrieved Situ Yinuo's exit record, however, the result was that two years ago, that is, Situ Yinuo did go through the procedures for studying abroad, and she did go abroad, but less than a week after she went abroad, she returned to Huaxia again, and then, there was no record of going abroad.

According to the identity information provided by her parents, the police investigated that after Situ Yinuo returned from abroad, she did not stay in Zhouhua City, but came to S City again, and lived in a three-star hotel in S City for half a month, after that, she chose to check out, and after that, where she went, it was impossible to investigate, in short, Situ Yinuo's last place was not abroad, but in a three-star hotel in S City, after that, she disappeared and her whereabouts have been unknown since then.

Situ Yinuo is missing, so, what kind of work is she doing in S City, or has she changed her identity and continued to live, or has she been killed?

Whatever the possibility, the first thing to figure out is that Situ Yinuo did not study abroad, but what was the purpose of coming to S City?

When Luo Jiayan investigated here, she immediately thought of Chen Zhen, because Situ Yinuo's university was studying at S University, if it was possible to make Situ Yinuo give up his good future and come to S City desperately, there may be no other reason except for his beloved.

If it is a person who has already entered the society and started to work, he may not do this, after all, they already have a certain amount of social experience, but Situ Yinuo is just a fledgling who has just graduated from college and has no social experience, and at Situ Yinuo's age, she often cares about love very much, and it is understandable that she does this.

Since she had this guess, Luo Jiayan got Situ Yinuo's social account from Situ Yinuo's parents and handed it to Lu Xing to crack it to see if she could find some clues from her social account.
