Hattori Heiji looked around at everyone's expressions, and then explained proudly.
"The heart stops beating after death, and even if the arteries are cut, the amount of bleeding will be limited. Therefore, such a large amount of bleeding at the scene was caused by the deceased before death. But now, judging from the blood coagulation condition of the deceased at the scene, the time of death of the deceased is not far from now.
Not far away. When I entered the store, I found that there was surveillance at the entrance. The murderer leaving the scene in such a short time would have been too conspicuous, so in order not to be suspected, the murderer must still be hiding among you guys at the scene!"
"But the murderer doesn't have to go through the front door when he comes in or leaves."
Gao Yuan was speechless.
"But Mingzhi, you have to know that in addition to the front door of our store, the back door is always locked from the inside. If the murderer doesn't take the front door, there will be no other way out."
Store manager Kinoshita Kawashi explained.
"That's right. When I first came here, I took a look at the back of the store and found that the door was indeed locked from the inside. If the murderer really left from there, it could only be that the murderer had an accomplice who was still in the store.
But no matter what, you guys at the scene are all suspects, either the real culprits or accomplices!"
Hattori Heiji said excitedly, especially after hearing Takato's narration just now, he seemed even more proud.
Gao Yuan sighed, "There was actually something strange about the scene. There was so much blood, but the murderer didn't step on it and leave any footprints. As you said, such a large amount of blood was left by the deceased before he died.
.Considering the cause of death of the deceased, the murderer must still be at the scene before the death of the deceased, so it is strange that the murderer did not step on the scene when he left the scene that was already full of blood."
"What's the matter? The murderer just needs to pay more attention. You see, Officer Otaki didn't step on him when he entered."
Hattori Heiji said nonchalantly, "And when the murderer left, the blood might not have spread like this."
Gao Yuan knew that he had missed the point, so he continued to explain.
"Don't you think the murderer would look suspicious if he left the box carefully through the door? What would you do if you were the murderer and wanted to leave the scene and didn't want to be discovered?"
"Needless to say, of course I have to make sure that no one is in the corridor anymore..."
Hattori Heiji said, suddenly realizing what Takato wanted to say.
If the murderer leaves the box through the door, then in order to ensure that he will not be discovered, it is best to confirm that there is no one in the corridor. But once he does this, he must get close to the door to listen to what is going on outside, or it is best to see it with his own eyes.
Look at the situation outside the door, but there is only so much space in the entire box. To do this, you must get close to the door. At that time, the blood stains in the box should have spread to the door. In this case, the murderer would have to confirm that no one was outside the door.
It's too difficult. Unless the murderer doesn't confirm at all and just opens the door and leaves. But is the murderer really so bold and not afraid of being seen?
Looking at Takato, Hattori Heiji understood that Takato had already thought of this before he said what he said before, but if so, how did the murderer leave?
Looking at the situation inside the box again, Hattori Heiji noticed the vent on the roof.
"You mean, the murderer entered the scene through the ventilation duct? Impossible, this vent is fixed and sealed with screws. Even if the murderer enters the scene through it, the screws must be removed.
It’s impossible that the deceased wouldn’t notice such a movement! Unless the murderer knew the deceased and was not surprised by the murderer’s appearance... But that’s not right, the murderer should obviously have a big grudge against the deceased!”
After thinking for a long time, Hattori Heiji felt that his head was a little big, and he felt that he was being taken in.
"It may not be as complicated as you think, but the truth depends on the condition of the vents. Officer Otaki, please go up and have a look to see if there is any glue or other things left on the edges of the vents."
Gao Yuan said.
"Do you suspect that the vent was removed from the beginning and then fixed with glue or something, and that the murderer only had to push hard when he came in? Then he used screws to fix it when he left, so that he would not be discovered?"
Hearing the word "glue" in Takato's words, Hattori Heiji understood it.
Takato responded with "Yeah", which made Hattori Heiji feel that he had underestimated this young man who claimed to be a detective.
Of course, it is not a great thing to be able to think of this, but because a similar technique had appeared in the Lavender Villa incident before, so when Gao Yuan thought that the murderer might come and go through the vents, he naturally aroused this suspicion.
Officer Otaki immediately took action, stepped on the table, reached out to the edge of the vent and touched it carefully. Sure enough, he felt some sticky touch, and gave an affirmative answer.
"If this is the case, the murderer obviously came to this box in advance to do some tricks, but how could the murderer be sure that the deceased would come to this box?"
Hattori Heiji said in confusion.
"Before that, I have a question."
Gao Yuan looked at the employee who had just returned from the front desk with registration materials.
"Did the network problems in our store occur after the deceased came to the store?"
When asked, the employee suddenly seemed to remember something, "It seems like this. I remember that the deceased came to our store to access the Internet for the first time that day. Soon after, we received complaints from customers that the network in the store was poor, and the deceased
It was a rare customer who did not come to complain that day, so I have some impressions."
After hearing this, store manager Kinoshita Kawashi looked at Gao Yuan and seemed to understand something.
"Akechi, what do you mean by asking?"
"Well, I have been managing the store's network these days and found that the culprit of network fluctuations comes from the store. It seems that someone came to the store to surf the Internet and installed malware on the store's computers, thus affecting the entire store's network. And the deceased has been using it every day.
Come here, I can't help but be a little suspicious."
The store manager asked questions as if seeking confirmation and received a positive answer from Gao Yuan.
"But why would he do this?"
Kinoshita Kawashi wondered, while Hattori Heiji on the side heard the unexpected clue and pricked up his ears to listen.
Gao Yuan really hadn't thought about this problem in detail. He thought about it briefly, and suddenly, Gao Yuan asked: "Did the network problem only occur after the employee asked for leave?"
After Gao Yuan asked this question, the employees in the store suddenly understood and said that it was indeed the case.
Hattori Heiji, who listened to their remarks, also said: "Speaking of the fact that the murderer this time wanted to do something in the store in advance, it shows that he knows the structure of this Internet cafe very well. In other words, the employee who asked for leave you mentioned is very
It’s suspicious!”
At this time, the siren sounded outside the door, and the police who had just received the alarm came to the scene. However, the people who came seemed to be Officer Otaki's subordinates. The deployment of the scene was quickly arranged by Officer Otaki. In addition to the on-site protection and evidence collection
In addition, they also specially sent police officers to investigate the ventilation ducts, and then taking into account what Hattori Heiji said just now, they planned to go to the home of the employee who was on leave to investigate.
"How about it? Do you want to go to the home of the employee who is on leave?"
Hattori Heiji extended an invitation to Takato.
Just when Gao Yuan was about to agree happily, an employee ran over in a panic and said to Kinoshita Kawashi: "Store manager! Something's wrong! The server in the store..."
Hearing this, Gao Yuan's expression changed slightly and he ran towards the main computer that manages the server in the store. The store manager and Hattori Heiji also followed him. Seeing Hattori in such a hurry, Kazuha and Officer Otaki also hurriedly followed.
.
When I came to the main computer, I saw that all the data in the server was being deleted by an unknown program!
A virus program bypassed the firewall I wrote! And the emergency program was not triggered!
Gao Yuan made several emergency operations but was unable to save his life!
