Qin Kai and Xia Hongyun came to the security room at the entrance of the community, saying that they wanted to take a look at last night's surveillance video, but the security guard pressed the boot button of the computer but there was no response, checked the power supply and wiring, and muttered: "Strange, the computer is broken?"

Qin Kai went over to pick up the main machine, and found that it was fluttering, and the screws in the back had been unscrewed. When I opened the case, there was nothing inside, and the motherboard and hard disk had all been removed.

The security guard was shocked: "How could this happen, there was obviously someone on duty last night!"

Xia Hongyun frowned and said, "Why does the murderer always think of us? ”

Qin Kai said lightly: "There is a surveillance video in this community, as long as it is a normal person, they will think of destroying evidence." ”

The murderer should have investigated the situation in this community, judging from the surveillance video footage, the cameras are installed in remote corners, if you are not familiar with the layout of the community, familiar with these cameras, it is impossible to accurately destroy the evidence.

Qin Kai looked at the duty schedule on the wall and asked, "When did you and that security guard take over?"

The security guard replied, "It's five o'clock this morning." ”

Qin Kai continued to ask, "Did you see him with your own eyes?"

The security guard scratched his cheeks and said, "See, we talked about football for a while." ”

Qin Kai smiled coldly: "You are lying, you are wearing socks of different colors on your feet, which means that you are in a hurry when you get up, you are late in the morning, and you have not worked with him at all." After a pause, I added, "Your colleague may have committed suicide!"

Hearing Qin Kai say this, the security guard admitted with a panicked face that he was indeed late in the morning, and he thought that his colleague Xiao Liu had already left, so he didn't think much about it.

"Do you know that there was a big murder here, but you deliberately lied, and I will ask my colleague to take you to make a detailed transcript. Xia Hongyun took out her documents, unfolded them in front of the security guard, and said coldly.

The security guard knelt on the ground in fright and pleaded: "Officer, I was really wrong, but I was afraid that the owner would know that I was late, so I lied." I didn't even know that there was a huge murder here! I didn't dare to hide it from the murderer. ”

Xia Hongyun sneered, in addition to trusting Qin Kai now, she used a suspicious gaze and attitude towards everyone, no matter how sincere the security guard said, she also subconsciously regarded him as a murder suspect.

"Whether you are hiding it for the murderer, we will investigate it. Xia Hongyun said coldly.

Qin Kai said: "Captain Xia, let him go, he can't be the murderer, and he won't know who the murderer is, and if you ask, it's in vain." ”

Xia Hongyun snorted and didn't speak, accepting Qin Kai's suggestion.

Qin Kai used his "ice eye" to take a look, there were not many clues in the house, and when he walked outside, he found that a security guard's glove had fallen from the grass on the side of the road, and another glove was thrown a little farther away.

"Captain Xia, come and take a look. Qin Kai took the Ice Eye Pupil Technique and called Xia Hongyun over.

"What did you find?" Xia Hongyun was overjoyed, jumped out of the window, squatted beside Qin Kai and asked.

Qin Kai pointed to the two gloves and said, "This glove is the same as the glove of the security guard just now, and it is likely that it was left by the previous security guard." Judging by the distance of the gloves, he left here on his own initiative. ”

"Why did he leave this place?" Xia Hongyun asked strangely.

"Wouldn't you know if you went and took a look?" Qin Kai said.

Qin Kai chased in this direction, Xia Hongyun followed behind Qin Kai, this was Qin Kai's request, they were facing a terrible murderous weapon, with Xia Hongyun's skills, he was not the opponent of the murderous weapon at all, Qin Kai had to protect Xia Hongyun.

The two walked for a while, and finally Qin Kai and Xia Hongyun came to a construction site.

But the two didn't find anything, Qin Kai didn't give up, and asked Xia Hongyun to call the other policemen. Xia Hongyun took out the walkie-talkie, explained her location clearly, and asked the criminal police of a detachment to come over.

Soon, a detachment of criminal police rushed over and alarmed the workers who were working on the construction.

The person in charge of the construction site saw a large group of policemen coming in and came over to ask what was going on, Qin Kai said: "There may have been a person in a security uniform who walked in last night, are you on duty here?"

The person in charge was about to contact the person on duty last night, when suddenly a worker exclaimed: "There is a person in the mixer!"

Qin Kai and Xia Hongyun looked over and saw that there was a person wrapped in a pile of cement slurry, and they could vaguely see the security uniform on his body, the workers didn't know it at first, they poured stones and cement into it, and suddenly got stuck after stirring for a while, only to find out.

"Protect the scene!" Xia Hongyun immediately ordered to go down, let the police block the scene, and sent someone to notify Mo Wenya to come over for an autopsy, and at the same time, let people check the surveillance video of the construction site, control the person in charge of the construction site and the people on duty last night, and ask them to be detailed in their confessions.

Mo Wenya came over, and after taking a look at the corpse, she said to Xia Hongyun: "I still have to get the corpse out." ”

Xia Hongyun nodded and called a few policemen to get the body out.

It saved a lot of effort to get the corpse out, the corpse had been stirred up beyond recognition, and many workers were frightened, especially the worker just now, who was even more frightened and pale, trembling all over, and didn't know what to do. Qin Kai comforted him and said, "Don't be afraid, you didn't kill people! ”

The worker nodded in panic, seeing that Qin Kai was also on the police's side, his heart was a little calm, even the police thought that he didn't kill the person, so this person's death really had nothing to do with him.

The current situation did not allow Qin Kai and them to carry each corpse back for careful examination, and there was no need for this. So Qin Kai and Mo Wenya connected a water hose together, washed the corpse, and then stepped forward to inspect it, and found that he had died by cutting his throat with a sharp stone chip.

Judging from the turbidity of the pupils, the time of death was less than six hours, Mo Wenya performed an autopsy and analysis of the corpse according to the routine, while Qin Kai stared at the corpse in a daze, Xia Hongyun came over and asked, "Qin Kai, is there anything suspicious about this corpse?"

Qin Kai frowned and said, "I feel a little strange, just now, I saw a bed in the security room, the quilt was spread out, the deceased slept all night last night. Moreover, in the drawer of the table, I found a bottle of liquor and peanuts, and judging from the corpse, there was a trace of alcohol on him, indicating that he had drunk last night and drank a lot. ”。

Xia Hongyun shook her head, saying that she didn't understand, what does this have to do with the death of the security guard? Could it be that the security guard did not do his duty, and the murderer killed him when he didn't like him?

What exactly did the murderer mean by doing this, and for what purpose?
