Chen Shi walked into the office and began to report on the results of the investigation into the identity of the deceased.

Xu Lei, male, 19 years old, from Xiacheng District, Baiyin City, his mother died of hemorrhage when he was born.

His father was a gang member in Xiacheng District, and when Xu Lei was ten years old, he died in a fight due to conflicts with other gangs.

Xu Lei has lived with his grandmother since he was a child, and he was finally admitted to high school, but during school, because of his pursuit of a female classmate, he had a conflict with another suitor, and he accidentally injured him, and Xu Lei was expelled.

Since then, he has been wandering in the lower town.

More than a month ago.

His grandmother, who had been raising him, died, and Room 601 was the only inheritance his grandmother left him.

According to the interview, since the death of his grandmother, Xu Lei has returned home and rarely goes out, except for the boss he followed who recently contacted him, few people have seen him.

After reporting the basic information, Chen Shi saw that Fang Mu and Liu Tao did not speak, so he continued to report the cause of death of the deceased and the results of the on-site investigation.

"The time of death of the deceased was around 1:30 to 2:30 a.m. on April 4, and the cause of death was blunt force blows to the back of the head and intracranial hemorrhage."

"The deceased was killed by one blow, there were no resistance injuries on his body, but there were restraint injuries, there were wires wrapped around his neck, there were obvious strangulation marks, and after a forensic autopsy, the restraint injuries were caused by the deceased after his death, the purpose was to keep the deceased's body upright by the window, what the murderer's purpose was in doing this, it is not clear for the time being."

"The wire that bound the neck of the deceased was a three-meter-long charging cable, which was the deceased's own thing."

"The murder weapon was a common tool hammer, which was abandoned by the killer in the grass behind the residential building."

"We found biological samples such as blood stains and hair of the deceased on the murder weapon, and determined that the tool hammer was the murder weapon that killed Xu Lei."

"In addition, we also found half a bloody fingerprint on the handle of the murder weapon, and through blood test comparison, the blood stains did not belong to the deceased Xu Lei, but from another deceased Chen Xuefeng, and the fingerprint comparison results have not yet come out."

"After comparing the murder weapons, the murder weapon that killed Xu Lei and the murder weapon that killed Chen Xuefeng are not the same, but whether it is the model, or the degree of new and old, it is basically the same."

"Also, the scene is messy, but there are traces of being cleaned, and we haven't been able to find any traces related to the murderer at the scene."

"At the moment, that's basically all we have."

After listening to Chen Shi's report, Fang Mu and Liu Tao frowned, and their expressions were extremely heavy.

According to the existing clues, it all shows that Xu Lei's death is directly related to the 404 case.

After a long silence, in the end, it was Liu Tao who took the lead to speak.

"From this point of view, Xu Lei's death is likely to be the murderer of the 404 case."

Regarding Liu Tao's opinion, Fang Mu neither objected nor agreed.

"Why did the murderer kill Xu Lei? What is the motivation? What is the purpose? ”

When Liu Tao heard this, he thought about it and said: "It may be that Xu Lei witnessed the whole process of the 404 case and was discovered by the murderer, so he killed him." ”

"Since Xu Lei witnessed the murder, why didn't he call the police as soon as possible?"

Liu Tao didn't think about it: "Because he is a gang member, you also know that those people in Xiacheng District don't trust our police, not to mention, they are still the target of our attack." ”

Fang Mu glanced at Liu Tao, then turned his head to look at Chen Shi and asked, "Is Xu Lei a gang member?" ”

Chen Shi shook his head and said: "It's barely true, but, according to the gang members themselves, Xu Lei didn't join them and has been wandering around the gang." ”

Fang Mu asked again: "Did Xu Lei call anyone else before he was killed?" ”

Chen Shi flipped through the information in his hand, shook his head, and said, "No, we retrieved Xu Lei's call records, and the last call was at ten o'clock in the evening on the 3rd, and it was a takeaway call." ”

Fang Mu nodded, turned his head to look at Liu Tao and said, "I didn't call the police, nor did I call others, this is obviously not like the reaction after witnessing the murder." ”

"Maybe it's because I'm afraid to forget?" Chen Shi said tentatively.

When Fang Mu and Liu Tao heard this, they shook their heads.

What Chen Shi said may not be nothing, but it is small.

Chen Shi also realized this, frowned and said: "In this way, Xu Lei probably didn't see anything, but in this way, why did the murderer kill him?" Could it be that the 404 murderer found someone in room 601 and thought that Xu Lei might have seen him, so he went to kill for the sake of caution? ”

Liu Tao was flipping through the on-site report and the surrounding investigations, and when he heard this, he shook his head and said: "Although there is such a possibility, it is not established. ”

"Why?"

Liu Tao raised the information in his hand and said: "In the residential building near the scene of the 404 crime, there are three or four residents, but they are all elderly, if the murderer really killed for this purpose, killing one is also killing, why don't he kill everyone, anyway, there are not many people." ”

When Chen Shi heard this, he subconsciously wanted to refute it, thinking that this was impossible, and the murderer could not be so perverted.

But he immediately thought of the tragic deaths of Chen Xuefeng and Shen Jiayi.

Chen Xuefeng and Shen Jiayi suffered inhuman torture before they died, and it lasted for a long time, which shows that the murderer is a pervert and has no humanity.

If the murderer really wants to kill people, it is not impossible to kill all the residents of the residential building, and it is very likely.

"Is it because Xu Lei is a young man?"

Liu Tao rolled his eyes and said angrily: "How does the murderer know if Xu Lei is a young man or an old man?" Could it be that the murderer went to step on it before committing the crime? ”

Chen Shi's eyes lit up and said, "Step on the point? That's right, the murderer will definitely step on the spot before committing the crime. ”

“……”

As soon as these words came out, Liu Tao was speechless in an instant.

Glancing at Chen Shi, he turned his head to look at Fang Mu, and complained, "This is the first graduate in the grade?" It's better than the assistant police at the police station. ”

Fang Mu was also very helpless, but seeing Chen Shi's blank expression, he still said patiently: "I have time to read more of the report of the visit and investigation." ”

"There are very few residents in the residential buildings near the crime scene, there is only one entrance and exit, if there are strangers entering and exiting, they will definitely be seen, but when we visited and investigated, they didn't see it, so we ......."

After Fang Mu's reminder, Chen Shi hurriedly picked up the information and looked at it, but he didn't see that there were strangers coming in and out recently.

However, Chen Shi's words reminded Fang Mu.

"The murderer chose to commit the crime on Xiacheng Street, it must have been planned in advance, and the case a month ago also happened on Xiacheng Street, which shows that the murderer is very familiar with Xiacheng Street."
